Energy Conservation Program: Test Procedures for Residential 
Dishwashers, Dehumidifiers, and Conventional Cooking Products

AGENCY: Office of Energy Efficiency and Renewable Energy, Department of 
Energy.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The U.S. Department of Energy (DOE) establishes new test 
procedures for residential dishwashers and dehumidifiers, and amends 
the currently applicable test procedure for conventional cooking 
products under the Energy Policy and Conservation Act. The new test 
procedures include provisions for measuring standby mode and off mode 
energy consumption, and update the provisions for measuring active mode 
energy consumption and, for dishwashers, water consumption. This final 
rule also amends the certification, compliance, and enforcement 
requirements for dishwashers, dehumidifiers and conventional cooking 
products, amends certain provisions in the currently applicable 
dishwasher test procedure, and eliminates an obsolete energy efficiency 
metric in the dishwasher test procedure and provisions in the cooking 
products test procedure that have become obsolete due to the 
elimination of standing pilot lights.

DATES: Effective date: The effective date of this rule is December 17, 
2012.
    Compliance Dates: The new test procedures for dishwashers and 
dehumidifiers and the final rule changes to the currently applicable 
test procedure for conventional cooking products will be mandatory to 
demonstrate compliance with the applicable energy conservation 
standards starting on the compliance date of any amended standards for 
dishwashers, dehumidifiers, and conventional cooking products. For 
dishwashers, this date will be May 30, 2013, the compliance date of the 
direct final rule published on May 30, 2012, unless the direct final 
rule is withdrawn as a result of adverse comment. Use of the 
replacement items for obsolete dishware, flatware, and food items in 
the currently applicable dishwasher test procedure will be required on 
December 17, 2012. Voluntary early use of the new dishwasher and 
dehumidifier test procedures and the final rule changes to the 
currently applicable test procedure for conventional cooking products 
to demonstrate compliance with applicable energy conservation standards 
or for representations of energy use (including the new standby mode 
and off mode provisions) is permissible on or after December 17, 2012.
    The incorporation by reference of certain publications listed in 
this rulemaking is approved by the Director of the Office of the 
Federal Register as of December 17, 2012.

I. Authority and Background

    Title III of the Energy Policy and Conservation Act (42 U.S.C. 
6291, et seq.; ``EPCA'' or, ``the Act'') sets forth a variety of 
provisions designed to improve energy efficiency. (All references to 
EPCA refer to the statute as amended through the Energy Independence 
and Security Act of 2007 (EISA 2007), Public Law 110-140 (Dec. 19, 
2007)). Part B of title III, which for editorial reasons was 
redesignated as Part A upon incorporation into the U.S. Code (42 U.S.C. 
6291-6309), establishes the ``Energy Conservation Program for Consumer 
Products Other Than Automobiles.'' These include residential 
dishwashers, dehumidifiers, and conventional cooking products,\1\ the 
subject of today's final rule. (42 U.S.C. 6292(a)(6) and (10); 
6295(cc))
---------------------------------------------------------------------------

    \1\ The term ``conventional cooking products,'' as used in this 
notice, refers to residential electric and gas kitchen ovens, 
ranges, and cooktops (other than microwave ovens).
---------------------------------------------------------------------------

    Under EPCA, this program consists essentially of four parts: (1) 
Testing, (2) labeling, (3) Federal energy conservation standards, and 
(4) certification and enforcement procedures. The testing requirements 
consist of test procedures that manufacturers of covered products must 
use as the basis for certifying to DOE that their products comply with 
the applicable energy conservation standards adopted under EPCA, and 
for making representations about the efficiency of those products. 
Similarly, DOE must use these test requirements to determine whether 
the products comply with any relevant standards promulgated under EPCA.

A. General Test Procedure Rulemaking Process

    Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures 
DOE must follow when prescribing or amending test procedures for 
covered products. EPCA provides that any test procedures prescribed or 
amended under this section shall be reasonably designed to produce test 
results which measure energy efficiency, energy use or estimated annual 
operating cost of a covered product during a representative average use 
cycle or period of use and shall not be unduly burdensome to conduct. 
(42 U.S.C. 6293(b)(3))
    In addition, if DOE determines that a test procedure amendment is 
warranted, it must publish proposed test procedures and offer the 
public an opportunity to present oral and written comments on them. (42 
U.S.C. 6293(b)(2)) Finally, in any rulemaking to amend a test 
procedure, DOE must determine to what extent, if any, the proposed test 
procedure would alter the measured energy efficiency of any covered 
product as determined under the existing test procedure. (42 U.S.C. 
6293(e))
    EPCA, in relevant part, requires DOE to amend the test procedures 
for all residential covered products to include measures of standby 
mode and off mode energy consumption. Specifically, EPCA provides 
definitions of ``standby mode'' and ``off mode'' (42 U.S.C. 
6295(gg)(1)(A)) and permits DOE to amend these definitions in the 
context of a given product (42 U.S.C. 6295(gg)(1)(B)). The statute 
requires integration of such energy consumption into the overall energy 
efficiency, energy consumption, or other energy descriptor for each 
covered product, unless the Secretary determines that--
    (i) The current test procedures for a covered product already fully 
account for and incorporate the standby mode and off mode energy 
consumption of the covered product; or
    (ii) such an integrated test procedure is technically infeasible 
for a particular covered product, in which case the Secretary shall 
prescribe a separate standby mode and off mode energy use test 
procedure for the covered product, if technically feasible. (42 U.S.C. 
6295(gg)(2)(A))
    Any such amendment must consider the most current versions of IEC 
Standard 62301, ``Household electrical appliances--Measurement of 
standby power,'' and IEC Standard 62087, ``Methods of measurement for 
the power consumption of audio, video, and related equipment.'' \2\ Id.
---------------------------------------------------------------------------

    \2\ DOE also considered IEC Standard 62087, which addresses the 
methods of measuring the power consumption of audio, video, and 
related equipment and is therefore not applicable to the products at 
issue in this rulemaking.
---------------------------------------------------------------------------

B. Summary of Current Test Procedures

1. Dishwashers
    DOE's test procedure for dishwashers is found in the Code of 
Federal Regulations (CFR) at 10 CFR part 430, subpart B, appendix C. 
DOE originally established its test procedure for dishwashers in 1977. 
42 FR 39964 (Aug. 8, 1977). Since that time, the dishwasher test 
procedure has undergone a number of amendments, as discussed below. In 
1983, DOE amended the test procedure to revise the representative 
average-use cycles to more accurately reflect consumer use and to 
address dishwashers that use 120 degrees Fahrenheit ([deg]F) inlet 
water. 48 FR 9202 (Mar. 3, 1983). DOE amended the test procedure again 
in 1984 to redefine the term ``water heating dishwasher.'' 49 FR 46533 
(Nov. 27, 1984). In 1987, DOE amended the test procedure to address 
models that use 50[emsp14][deg]F inlet water. 52 FR 47549 (Dec. 15, 
1987). In 2001, DOE revised the test procedure's testing specifications 
to improve testing repeatability, changed the definitions of ``compact 
dishwasher'' and ``standard dishwasher,'' and reduced the average 
number of use cycles per year from 322 to 264. 66 FR 65091, 65095-97 
(Dec. 18, 2001). In 2003, DOE again revised the test procedure to more 
accurately measure dishwasher efficiency, energy use, and water use. 
The 2003 dishwasher test procedure amendments included the following 
revisions: (1) The addition of a method to rate the efficiency of soil-
sensing products; (2) the addition of a method to measure standby 
power; and (3) a reduction in the average-use cycles per year from 264 
to 215. 68 FR 51887, 51899-903 (Aug. 29, 2003). The current version of 
the test procedure includes provisions for determining estimated annual 
energy use (EAEU), estimated annual operating cost (EAOC), energy 
factor (EF) expressed in cycles per kilowatt-hour (kWh), and water 
consumption expressed in gallons per cycle. 10 CFR 430.23(c).
2. Dehumidifiers
    The DOE test procedure for dehumidifiers is found at 10 CFR part 
430, subpart B, appendix X. EPCA specifies that the dehumidifier test 
procedure must be based on the U.S.

[[Page 65944]]

Environmental Protection Agency's (EPA) test criteria used under the 
ENERGY STAR \3\ program unless revised by DOE. (42 U.S.C. 6293(b)(13)) 
The ENERGY STAR test criteria effective in January 2001 require that 
American National Standards Institute (ANSI)/Association of Home 
Appliance Manufacturers (AHAM) Standard DH-1, ``Dehumidifiers,'' be 
used to measure capacity and that the Canadian Standards Association 
(CAN/CSA) standard CAN/CSA-C749-1994 (R2005), ``Performance of 
Dehumidifiers,'' be used to calculate EF. DOE adopted those test 
criteria, along with related definitions and tolerances, as its test 
procedure for dehumidifiers. 71 FR 71340, 71347, 71366-68 (Dec. 8, 
2006). The DOE test procedure provides methods for determining the EF 
for dehumidifiers, which is expressed in liters (l) of water condensed 
per kWh.
---------------------------------------------------------------------------

    \3\ For more information on the ENERGY STAR program, see: 
www.energystar.gov.
---------------------------------------------------------------------------

3. Conventional Cooking Products
    DOE's test procedures for conventional ranges, cooktops, and ovens 
(including microwave ovens) are found at 10 CFR 430, subpart B, 
appendix I. DOE first established the test procedures included in 
appendix I in a final rule published in the Federal Register on May 10, 
1978. 43 FR 20108, 20120-28. DOE revised its test procedure for cooking 
products to more accurately measure their efficiency and energy use, 
and published the revisions as a final rule in 1997. 62 FR 51976 (Oct. 
3, 1997). These test procedure amendments included: (1) A reduction in 
the annual useful cooking energy; (2) a reduction in the number of 
self-cleaning oven cycles per year; and (3) incorporation of portions 
of IEC Standard 705-1988, ``Methods for measuring the performance of 
microwave ovens for household and similar purposes,'' and Amendment 2-
1993 for the testing of microwave ovens. Id. The test procedure for 
conventional cooking products establishes provisions for determining 
EAOC, cooking efficiency (defined as the ratio of cooking energy output 
to cooking energy input), and EF (defined as the ratio of annual useful 
cooking energy output to total annual energy input). 10 CFR 430.23(i); 
10 CFR 430 subpart B, appendix I. There is currently no EnergyGuide \4\ 
labeling program for cooking products.
---------------------------------------------------------------------------

    \4\ For more information on the EnergyGuide labeling program, 
see: www.access.gpo.gov/nara/cfr/waisidx_00/16cfr305_00.html.
---------------------------------------------------------------------------

    With respect to today's rulemaking, DOE issues a final rule 
amending its cooking products test procedure for conventional cooking 
products without addressing power consumption for microwave ovens. DOE 
is considering establishing a test procedure for active mode microwave 
oven energy use. (77 FR 33106 (June 5, 2012)) \5\ DOE has also 
initiated a separate test procedure rulemaking to address standby mode 
and off mode power consumption for microwave ovens. See 73 FR 62134 
(Oct. 17, 2008); 75 FR 42612 (July 22, 2010); 76 FR 12825 (March 9, 
2011) (hereafter referred to as the March 2011 Interim Final Rule). 76 
FR 72332 (Nov. 23, 2011); 77 FR 28805 (May 16, 2012).
---------------------------------------------------------------------------

    \5\ DOE repealed its previous test procedure to measure the 
active mode energy use for microwave ovens after determining that 
the procedure did not procedure accurate and repeatable results. 75 
FR 42579 (July 22, 2010).
---------------------------------------------------------------------------

C. Summary of the Current Rulemaking

1. The December 2010 NOPR
    On December 2, 2010, DOE published a Notice of Proposed Rulemaking 
(NOPR) (hereafter referred to as the December 2010 NOPR) in which it 
proposed to incorporate by reference into the test procedures for 
dishwashers, dehumidifiers, and conventional cooking products specific 
provisions from IEC Standard 62301 ``Household electrical appliances--
Measurement of standby power,'' First Edition 2005-06 (IEC Standard 
62301 (First Edition) or ``First Edition'') regarding test conditions 
and test procedures for measuring standby mode and off mode power 
consumption. 75 FR 75290, 75295-97. DOE also proposed to incorporate 
into each test procedure definitions of ``active mode,'' ``standby 
mode,'' and ``off mode'' based on the definitions for those terms 
provided in the most current draft of an updated version of IEC 
Standard 62301. Id. at 75297-300. Further, DOE proposed to include in 
each test procedure additional language that would clarify the 
application of clauses from IEC Standard 62301 (First Edition) for 
measuring standby mode and off mode power consumption.\6\ Id. at 75300-
04. DOE held a public meeting on December 17, 2010 (hereafter referred 
to as the NOPR Public Meeting) to receive comments on the December 2010 
NOPR, and accepted written comments, data, and information until 
February 15, 2011. Commenters to the December 2010 NOPR suggested that 
the draft updated version of IEC Standard 62301 would provide practical 
improvement to the mode definitions and testing methodology for the 
test procedures that are the subject of this rulemaking.
---------------------------------------------------------------------------

    \6\ EISA 2007 directs DOE to also consider IEC Standard 62087 
when amending its test procedure to include standby mode and off 
mode energy consumption. See 42 U.S.C. 6295(gg)(2)(A). DOE 
considered IEC Standard 62087 and determined that the standard 
addresses the methods of measuring the power consumption of audio, 
video, and related equipment and is therefore not applicable to the 
products addressed in today's proposal.
---------------------------------------------------------------------------

2. The September 2011 Supplemental Notice of Proposed Rulemaking 
(SNOPR)
    The IEC adopted and published IEC Standard 62301, ``Household 
electrical appliances--Measurement of standby power,'' Edition 2.0 
2011-01 (IEC Standard 62301 (Second Edition) or ``Second Edition'') on 
January 27, 2011. DOE reviewed this latest version of the IEC standard 
and determined that it improves some measurements of standby mode and 
off mode energy use. Accordingly, DOE proposed in an SNOPR published in 
the Federal Register on September 20, 2011 (76 FR 58346) (hereafter 
referred to as the September 2011 SNOPR), to incorporate certain 
provisions of the IEC Standard 62301 (Second Edition), along with 
clarifying language, into the DOE test procedures for residential 
dishwashers, dehumidifiers, and conventional cooking products. Other 
than the specific amendments proposed in the September 2011 SNOPR, the 
test procedure amendments in the December 2010 NOPR were not affected.
3. The May 2012 SNOPR
    In response to comments received on the September 2011 SNOPR, DOE 
published an SNOPR on May 25, 2012 (77 FR 31444) (hereafter referred to 
as the May 2012 SNOPR). DOE proposed to amend the dishwasher test 
procedure to remove an obsolete efficiency metric and to include 
measures of energy consumption in fan-only mode, measures of energy and 
water consumption due to periodic water softener regeneration, and 
clarified specifications for the normal cycle, power supply, energy 
test cycle, detergent dosing, and test load requirements. DOE also 
proposed amendments to the cooking products test procedure to measure 
energy consumption in conventional oven fan-only mode and remove 
obsolete provisions for gas pilot lights in the cooking products test 
procedure. For dehumidifiers, DOE proposed to update the industry test 
method specified in the test procedure. These proposals addressed 
comments received from interested parties in response to the December 
2010 NOPR and September 2011 NOPR, and incorporated methods provided in 
test procedure waivers granted by DOE for certain water-softening 
dishwashers. (See 75 FR

[[Page 65945]]

62127 (Oct. 7, 2010) and 77 FR 33450 (June 6, 2012))
4. The August 2012 SNOPR
    In response to comments received on the May 2012 SNOPR and during a 
public meeting held June 1, 2012 (hereafter referred to as the 2012 
Public Meeting), DOE published an SNOPR on August 15, 2012 (77 FR 
49064) (hereafter referred to as the August 2012 SNOPR) proposing to 
update certain obsolete dishware, flatware and food items used in the 
dishwasher test procedure; \7\ amend the definition of the normal 
cycle, update the ambient temperature and preconditioning requirements; 
and update the referenced industry test method in the dishwasher test 
procedure. DOE also proposed to add water pressure, drain height, rack 
position, loading, rinse aid container, and soil preparation 
specifications to the dishwasher test procedure. DOE additionally 
proposed, for both dishwashers and cooking products, a revised test 
procedure to measure energy use in fan-only mode based on DOE analysis 
and comments received on the May 2012 SNOPR.
---------------------------------------------------------------------------

    \7\ The terms ``obsolete'' or ``nearly obsolete'' used in this 
context mean that the test load item, food item, or detergent is 
unavailable on the market or is available in such limited supply 
that it is not sufficiently available for testing purposes.
---------------------------------------------------------------------------

II. Summary of the Final Rule

    In this final rule, DOE establishes new test procedures for 
residential dishwashers and dehumidifiers, and amends the test 
procedures for conventional cooking products, to incorporate by 
reference provisions from IEC Standard 62301 (Second Edition) for the 
measurement of energy use in standby mode and off mode, and, for 
dishwashers and conventional cooking products, methodology for the 
measurement of fan-only mode energy use, in the energy efficiency 
metrics.
    In the new dishwasher test procedure established in today's final 
rule, DOE also: (1) Adds a measure of the annual energy and water use 
associated with periodic water softener system regeneration for those 
dishwashers equipped with such systems; and (2) incorporates by 
reference the updated industry test standard AHAM DW-1-2009, which upon 
acceptance by ANSI was designated as ANSI/AHAM DW-1-2010, American 
National Standard, ``Household Electric Dishwashers.''
    The final rule also clarifies in the new dishwasher test procedure: 
(1) The definitions of normal cycle, soil-sensing dishwasher, and non-
soil-sensing dishwasher; (2) power supply requirements during testing; 
(3) energy test cycle requirements for soil-sensing dishwashers; (4) 
test load specifications and soiling requirements; (5) detergent dosing 
specifications; (6) rinse aid dosing specifications; and (7) length of 
time soils may sit before they are applied to dishware.
    The final rule also amends the testing conditions in the new 
dishwasher test procedure by: (1) Specifying the use of two pre-
conditioning cycles to ensure the turbidity sensor is calibrated, (2) 
establishing maximum allowable time for the water pressure to reach the 
specified test conditions for improved repeatability and 
reproducibility, and (3) specifying drain height and rack position in 
the absence of manufacturer's instructions to improve reproducibility.
    In today's final rule, DOE also amends the current dishwasher test 
procedure to replace the obsolete flatware, dishware, and food items 
specified in the current test procedure with those proposed in Table 1 
of the August 2012 SNOPR, except that the current cup and saucer and 
alternate fruit bowl specifications are retained and the product 
numbers are updated. The same replacement items are specified in the 
new dishwasher test procedure.
    The final rule also updates the industry test method specified in 
the new dehumidifier test procedure. As noted above, EPCA specifies 
that the dehumidifier test procedure must be based on EPA's test 
criteria used under the ENERGY STAR program unless revised by DOE. (42 
U.S.C. 6293(b)(13)) The ENERGY STAR test criteria effective in January 
2001 require that ANSI/AHAM Standard DH-1, ``Dehumidifiers,'' be used 
to measure energy use. DOE incorporates the most current version of the 
DH-1 standard (DH-1-2008) into the new test procedure for 
dehumidifiers.
    Finally, today's final rule eliminates an obsolete metric from the 
dishwasher test procedure and provisions in the cooking products test 
procedure that have become obsolete due to the elimination of standing 
pilot lights. For cooking products, DOE eliminates measures of pilot 
light energy consumption from the test procedure. In a final rule 
published April 8, 2009, DOE established standards that prohibit 
constant-burning pilot lights in gas cooking products manufactured on 
or after April 9, 2012. 74 FR 16040. For dishwashers, DOE removes the 
calculation of EF from the dishwasher test procedure because the 
current dishwasher energy conservation standards no longer require it 
for compliance or representations.

III. Discussion

A. Products Covered by the Proposed Test Procedure Amendments

    The amendments adopted in today's final rule to the DOE test 
procedures cover dishwashers, which DOE currently defines as follows:

    Dishwasher means a cabinet-like appliance which with the aid of 
water and detergent, washes, rinses, and dries (when a drying 
process is included) dishware, glassware, eating utensils, and most 
cooking utensils by chemical, mechanical and/or electrical means and 
discharges to the plumbing drainage system. (10 CFR 430.2)

    Today's amendments to the DOE test procedures also cover 
dehumidifiers, which DOE currently defines as follows:

    Dehumidifier means a self-contained, electrically operated, and 
mechanically refrigerated encased assembly consisting of--
    (1) A refrigerated surface (evaporator) that condenses moisture 
from the atmosphere;
    (2) A refrigerating system, including an electric motor;
    (3) An air-circulating fan; and
    (4) Means for collecting or disposing of the condensate. Id.

    Finally, today's amendments to the DOE test procedures also cover 
cooking products, specifically conventional cooking products, which are 
currently defined as:

    Cooking products means consumer products that are used as the 
major household cooking appliances. They are designed to cook or 
heat different types of food by one or more of the following sources 
of heat: Gas, electricity, or microwave energy. Each product may 
consist of a horizontal cooking top containing one or more surface 
units and/or one or more heating compartments. They must be one of 
the following classes: conventional ranges, conventional cooking 
tops, conventional ovens, microwave ovens, microwave/conventional 
ranges and other cooking products.\8\
---------------------------------------------------------------------------

    \8\ As stated in Section I, DOE is addressing test procedures 
for microwaves in separate rulemaking proceedings.
---------------------------------------------------------------------------

    Conventional cooking top means a class of kitchen ranges and 
ovens which is a household cooking appliance consisting of a 
horizontal surface containing one or more surface units which 
include either a gas flame or electric resistance heating.
    Conventional oven means a class of kitchen ranges and ovens 
which is a household cooking appliance consisting of one or more 
compartments intended for the cooking or heating of food by means of 
either a gas flame or electric resistance heating. It does not 
include portable or countertop ovens which use electric resistance 
heating for the cooking or heating of food and are designed for an 
electrical supply of approximately 120 volts.
    Conventional range means a class of kitchen ranges and ovens 
which is a household cooking appliance consisting of a

[[Page 65946]]

conventional cooking top and one or more conventional ovens. Id.

    DOE did not propose any amendments to these definitions in the 
December 2010 NOPR, the September 2011 SNOPR, the May 2012 SNOPR, or 
the August 2012 SNOPR.
    Whirlpool Corporation (Whirlpool) commented that the definitions of 
conventional cooking top, conventional oven, and conventional range 
should include electromagnetic induction as a means of cooking or 
heating, so that induction cooking products would be covered. 
(Whirlpool, No. 12 at p. 2) \9\ DOE may consider amendments to its 
cooking products test procedure to address active, standby, and off 
mode energy use of induction cooking products in a separate rulemaking.

appears on page 2 of document number 12.
---------------------------------------------------------------------------

    BSH Home Appliances (BSH) asked how double ovens, microwave ovens, 
combination microwave ovens, and other combination products would be 
treated under this test procedure. (BSH, NOPR Public Meeting 
Transcript, No. 10 at pp. 21-22) \10\ DOE proposed in the December 2010 
SNOPR that the integrated energy factor of combinations of ovens and 
cooktops other than a kitchen range (i.e., a cooktop and oven 
combined), which would include products with two conventional ovens, 
would be the sum of the annual useful cooking energy output of each 
component divided by the sum of the total integrated annual energy 
consumption of each component, according to calculations newly provided 
in the test procedure. 75 FR 75290, 75333 (Dec. 2, 2010). DOE did not 
receive further comments or information regarding combination 
conventional cooking products, and this proposal was not affected by 
the subsequent SNOPRs. As discussed in Section I, DOE is addressing 
microwave ovens, including combination microwave ovens, in a separate 
rulemaking.

Transcript, No. 10 at pp. 21-22'' identifies an oral comment that 
DOE received during the December 17, 2010, NOPR public meeting, was

residential dishwasher, dehumidifier, and conventional cooking 
products test procedures rulemaking (Docket No. EERE-2010-BT-TP-
0039), and is available for review at www.regulations.gov. This 
particular notation refers to a comment (1) made by BSH Home 
Appliances during the public meeting; (2) recorded in document

which appears on pages 21-22 of document number 10.
---------------------------------------------------------------------------

    In the absence of additional comments or input, DOE does not amend 
its current definitions of dishwasher, dehumidifier, conventional 
cooking product, conventional cooking top, conventional oven, or 
conventional range in today's final rule.

B. Compliance Date

    In the December 2010 NOPR, DOE proposed that the amended test 
procedures for residential dishwashers, dehumidifiers, and conventional 
cooking products would become effective 30 days after the test 
procedure final rule is published in the Federal Register. Any added 
procedures and calculations for standby mode and off mode energy 
consumption resulting from implementation of EISA 2007, however, would 
not need to be performed to determine compliance with the current 
energy conservation standards. Manufacturers would be required to use 
the standby mode and off mode provisions to demonstrate compliance with 
DOE's energy conservation standards on the mandatory compliance date of 
a final rule establishing amended energy conservation standards for 
dishwashers, dehumidifiers, and conventional cooking products that 
address standby mode and off mode energy consumption. As of 180 days 
after publication of a test procedure final rule, any representations 
related to the standby mode and off mode energy consumption of these 
products would be required to be based upon results generated under the 
applicable provision of these test procedures, in accordance with 42 
U.S.C. 6293(c)(2). 75 FR 75290, 75294-95 (Dec. 2, 2010).
    In the May 2012 SNOPR, DOE proposed amendments clarifying the 
dishwasher test procedure that would apply on the effective date of the 
amended dishwasher test procedure (i.e., 30 days after the date of 
publication of the test procedure final rule in the Federal Register). 
77 FR 31444, 31450-52 (May 25, 2012). DOE also proposed methods by 
which the energy and water use of dishwasher water softener 
regeneration would be measured, as well as provisions to measure 
dishwasher and conventional cooking products fan-only mode energy 
consumption that would be required to be included in the energy 
efficiency metrics upon the compliance date of any updated dishwasher 
and conventional cooking product energy conservation standards 
addressing standby mode and off mode energy use. 77 FR 31444, 31451 
(May 25, 2012). In the August 2012 SNOPR, DOE proposed additional 
amendments to specify test load and soil items in place of obsolete or 
potentially obsolete items in the dishwasher test procedure that would 
be required 30 days after publication of the test procedure final rule 
in the Federal Register, and sought comment on whether the specified 
items could be procured in 30 days. (77 FR 49064, 49065 (Aug, 15, 
2012)).
    AHAM, BSH, Samsung Electronics America, Inc. (Samsung), and 
Whirlpool commented that DOE should clarify when the dishwasher test 
procedure amendments that could impact measured energy use, 
particularly the fan-only mode and water softener regeneration energy 
measurements, would be required for compliance with dishwasher energy 
conservation standards. These commenters stated that energy consumption 
in these modes should be included in the final metric to determine 
compliance with a future standard that has not yet been proposed, and 
not for compliance with the standard in the recent direct final rule. 
However, if these modes are included in the metric used to determine 
compliance with the standards in the direct final rule, the commenters 
stated that DOE must ensure that the stringency of the standards does 
not change. (AHAM, No. 20 at p. 3; AHAM, No. 27 at pp. 2-3; AHAM, No. 
35 at p. 2; BSH, No. 28 at p. 1; Samsung, No. 33 at p. 1; Whirlpool, 
No. 26 at pp. 1-2) According to BSH, adequate time will be needed to 
test all the different base models using the amended dishwasher test 
procedure and to determine whether sensor decisions need to be changed, 
which may include adjusting software and conducting additional tests. 
BSH also stated that time should be allowed to use any parts in the 
supply chain before manufacturers are required to use the new test 
procedure. In addition, BSH stated that past accepted test data that 
were based on the previous test procedure should continue to be 
accepted until production ceases. (BSH, No. 36 at pp. 1-2)
    The energy use of dishwasher water softener regeneration must be 
measured to demonstrate compliance with current energy conservation 
standards for dishwashers. In the test procedure waivers granted for 
water softening dishwashers, DOE has required that such models meet the 
current energy conservation standards with the additional energy and 
water use associated with water softener regeneration included in the 
annual

[[Page 65947]]

energy use and per-cycle water consumption metrics. (75 FR 62127 (Oct. 
7, 2010) and 77 FR 33450 (June 5, 2012)). In accordance with the 
approach specified in these waivers, DOE determines that the energy and 
water use must be included in the metrics used to demonstrate 
compliance with any amended dishwasher energy conservation standards, 
including those in the direct final rule. Compliance with the direct 
final rule will be required on May 30, 2013 unless the direct final 
rule is withdrawn as a result of adverse comment. 77 FR 31918 (May 30, 
2012).
    DOE has determined that use of the test procedures to measure the 
energy use in fan-only mode on the compliance date of any amended 
standards is appropriate. Compliance with the dishwasher standards 
published on May 30, 2012 will be required on May 30, 2013 unless DOE 
withdraws the direct final rule. The energy use in these modes is 
estimated to be less than 5 percent of the total energy use of standard 
dishwashers. Given that 65 percent of all standard dishwashers 
currently on the market meet or exceed the minimum energy conservation 
standards established in the direct final rule, inclusion of this small 
amount of energy use would not impact compliance with the revised 
standard. 77 FR 31918, 31948-31949. Therefore, DOE has determined that 
the energy use in fan-only mode is de minimus and insufficient to alter 
in a material manner the measured energy use of dishwashers. Therefore, 
DOE is not considering amending the standards set forth in the direct 
final rule.
    DOE is requiring that the clarifications to the dishwasher test 
procedure described in the May 2012 SNOPR, which include the definition 
of the normal cycle, energy test cycle selection, power supply 
requirements, test load specifications and soiling requirements (except 
for the specification of replacement items for some obsolete dishware 
and flatware) and detergent dosing specifications, be used on the 
compliance date of any amended standards for dishwashers (May 30, 2013 
unless the direct final rule is withdrawn). While DOE had earlier 
proposed that these requirements be mandatory 30 days after publication 
of the test procedure final rule in the Federal Register, DOE is 
adopting, as discussed below, amendments to the existing test procedure 
that specify replacement items for obsolete test load and soil items 
and technical corrections that will be required for use on or after 45 
days after publication of the test procedure final rule in the Federal 
Register. The remaining clarifications to the dishwasher test 
procedure, as well as the same specifications for replacement items, 
are provided in a new test procedure that will be required to be used 
on the compliance date of any amended standards for dishwashers (May 
30, 2013 unless the direct final rule is withdrawn).
    For the replacement of obsolete items, DOE did not receive any 
comments regarding the proposed requirement for the use of certain test 
load and soil items in place of obsolete or potentially obsolete items 
in the dishwasher test procedure 30 days after publication of the test 
procedure final rule in the Federal Register, nor did it receive 
comment on whether the specified items could be procured in 30 days. 
Because certain test load items may require purchase outside of the 
United States, however, 30 days may not allow sufficient time for 
acquisition. DOE concludes, therefore, that requiring the use of 
replacement test load and soil items 45 days after the publication of 
the final rule best weighs the need for manufacturers and test 
laboratories to utilize comparable testing items against the timeframe 
potentially required for obtaining the items.
    In sum, with the exception of requirements for the use of 
replacement items for obsolete dishware, flatware, and food items 
specified as amendments to the current dishwasher test procedure, the 
final rule changes will be mandatory to demonstrate compliance with the 
applicable energy conservation standard starting on the compliance date 
of any amended standards for dehumidifiers, dishwashers, and cooking 
products, as required under 42 U.S.C. 6295(s). For the amendments to 
the current dishwasher test procedure related to obsolete dishware, 
flatware, and food items, DOE has determined that use of these amended 
test procedure provisions would not alter a dishwasher's measured 
energy efficiency or measured energy use pursuant to 42 U.S.C. 
6293(e)(1). DOE has concluded that today's final rule accords 
manufacturers with sufficient time to implement the test procedure 
changes contained herein.
    In summary, DOE establishes a new dishwasher test procedure at 10 
CFR part 430, subpart B, appendix C1 that incorporates these final rule 
changes, including the use of replacement items. By amending the 
current test procedure to also include the use of replacement items, 
appendix C may continue to be used until the compliance date of amended 
dishwasher energy conservation standards. Similarly, DOE establishes a 
new dehumidifier test procedure at 10 CFR part 430, subpart B, appendix 
X1, but allows for the use of the current dehumidifier test procedure 
until the compliance date of amended dehumidifier energy conservation 
standards. Because the current energy conservation standards for 
conventional cooking products consist of a prescriptive design 
requirement prohibiting the use of constant-burning pilot lights, which 
do not require the use of the DOE test procedure to demonstrate 
compliance, DOE incorporates the final rule changes as amendments to 
the existing conventional cooking products test procedure codified at 
10 CFR part 430, subpart B, appendix I.
    For dishwashers, the date upon which the use of new appendix C1 
will be required will be May 30, 2013, the compliance date of the 
direct final rule published on May 30, 2012, unless the direct final 
rule is withdrawn. Until that date, manufacturers may continue to use 
appendix C to certify compliance with the current dishwasher energy 
conservation standards. Any products manufactured on or after that date 
must be certified to demonstrate compliance with the amended energy 
conservation standards using appendix C1. However, use of the 
replacement items for obsolete dishware, flatware, and food items in 
the amendments to the currently applicable dishwasher test procedure 
will be required on December 17, 2012.
    Today's final rule also clarifies that as of April 29, 2013, any 
representations related to the standby mode and off mode energy 
consumption of these products must be based upon results generated 
under the applicable provisions of appendix C1, appendix I, and 
appendix X1. Manufacturers may use the new dishwasher and dehumidifier 
test procedures and amended conventional cooking products test 
procedure prior to this date consistent with DOE guidance available at: 
http://www1.eere.energy.gov/buildings/appliance_standards/pdfs/tp_faq_2012-06-29.pdf.

C. Incorporation of IEC Standard 62301 (Second Edition) for Measuring 
Standby Mode and Off Mode Power Consumption

    The December 2010 NOPR proposed to incorporate in the test 
procedures for dishwashers, dehumidifiers, and conventional cooking 
products relevant provisions from IEC Standard 62301 (First Edition) 
for measuring standby mode and off mode power. The amended test 
procedures would use these measured wattages in calculations to 
incorporate standby mode and off

[[Page 65948]]

mode energy consumption into the test procedures. DOE reviewed the IEC 
Standard 62301 (First Edition) and tentatively concluded that it would 
be generally applicable to dishwashers, dehumidifiers, and conventional 
cooking products, although some clarification would be needed. 
Specifically, DOE proposed in the December 2010 NOPR for standby mode 
and off mode power measurements to provide a stabilization period of at 
least 30 minutes followed by an energy use measurement period of not 
less than 10 minutes for each of the covered products. 75 FR 75290, 
75295-300 (Dec. 2, 2010). Additionally, for conventional cooking 
products, DOE proposed a specific standby mode power measurement 
methodology for units in which power varies as a function of displayed 
time. 75 FR 75290, 75302-04 (Dec. 2, 2010). With these clarifications, 
the December 2010 NOPR proposed to reference IEC Standard 62301 (First 
Edition) for the standby mode and off mode wattage measurements. DOE 
also proposed in the December 2010 NOPR to amend the dishwasher, 
dehumidifier, and conventional cooking products test procedures to 
include new definitions of ``standby mode,'' ``off mode,'' and ``active 
mode'' based on the most current draft version of the Second Edition at 
that time (IEC Standard 62301 (FDIS)). 75 FR 75290, 75296-97 (Dec. 2, 
2010).
    In response to comments on the December 2010 NOPR, and because IEC 
Standard 62301 (Second Edition) was issued on January 27, 2011, DOE 
evaluated in the September 2011 SNOPR the applicability of the Second 
Edition for measuring standby mode and off mode energy use in the 
dishwasher, dehumidifier, and conventional cooking products test 
procedures. Commenters noted that IEC Standard 62301 (Second Edition) 
is an internationally-accepted test procedure for measuring standby 
power in residential appliances, and stated that they supported 
harmonizing the mode definitions with those in IEC Standard 62301 
(FDIS), which are substantively the same as those in IEC Standard 62301 
(Second Edition). 76 FR 58346, 58350 (Sep. 20, 2011). DOE thus 
maintained in the September 2011 SNOPR the definitions for active mode, 
standby mode, and off mode that it had proposed in the December 2010 
NOPR for dishwashers and dehumidifiers.
    The definitions for standby mode and off mode energy use for 
cooking products, as well as a slightly modified definition of active 
mode, were established in the cooking products test procedure by the 
March 2011 Interim Final Rule for microwave ovens. The definition of 
active mode established by the March 2011 Interim Final Rule includes 
the statement that delay start mode is a one-off, user-initiated, 
short-duration function that is associated with an active mode.\11\ The 
May 2012 SNOPR added reference to fan-only mode functions in active 
mode for dishwashers and cooking products. Detailed discussion of each 
of these mode definitions, including comments from interested parties, 
is presented in section III.D.
---------------------------------------------------------------------------

    \11\ Because DOE accepted comments on the March 2011 Interim 
Final Rule until shortly before publication of the September 2011 
SNOPR, DOE continued to include the cooking products mode 
definitions in this proposal.
---------------------------------------------------------------------------

    DOE determined that the updated version of IEC Standard 62301 
provides clarification to certain sections as compared to the First 
Edition. In particular, DOE proposed to incorporate by reference in the 
dishwasher, dehumidifier, and conventional cooking products test 
procedures the following provisions from IEC Standard 62301 (Second 
Edition): (1) The room ambient air temperature requirements in section 
4, paragraph 4.2; (2) the electrical supply voltage requirements in 
section 4, paragraph 4.3.2; (3) the power equipment specifications in 
section 4, paragraph 4.4; (4) the instructions for allowing the product 
to enter a lower power state prior to the test measurement in section 
5, paragraph 5.1, note 1; and (5) portions of the installation and 
setup procedures in section 5, paragraph 5.2. DOE also proposed that 
the measurement of standby mode and off mode power be made according to 
section 5, paragraph 5.3.2 in each of the test procedures, except in 
the case of conventional cooking products in which power varies as a 
function of the clock time displayed in standby mode. For such 
products, DOE tentatively concluded that the application of the test 
methodology from the Second Edition would cause manufacturers to incur 
significant burden that would not be warranted by any potential 
improved accuracy of the test measurement. Thus, DOE maintained its 
original proposal from the December 2010 NOPR for 10-minute and 12-hour 
test methods for these products in the conventional cooking products 
test procedure, in which case testers would be allowed to choose 
measuring standby power by means of either of the following methods:
(a) 10-Minute Test
    (1) Allow the product to stabilize according to section 5, 
paragraph 5.3 of IEC Standard 62301 (First Edition), which requires a 
minimum of 5 minutes;
    (2) Set the clock time to 3:23;
    (3) Allow another stabilization period until the clock time reaches 
3:33;
    (4) Use the average power approach in section 5, paragraph 5.3.2(a) 
to measure standby mode power for a period of 10 minutes +0/-2 seconds; 
or
(b) 12-Hour Test
    (1) At any clock time, allow the product to stabilize according to 
section 5, paragraph 5.3 of IEC Standard 62301 (First Edition), which 
requires a minimum of 5 minutes;
    (2) Use the average power approach in section 5, paragraph 5.3.2(a) 
to measure standby mode power for a period of 12 hours +0/-30 seconds.
    According to the proposal, manufacturers could elect to conduct 
either a 10-minute test, a 12-hour test, or both. Based on DOE testing, 
use of the 10-minute test period produced results that were within 
2 percent of the results for the full 12-hour test. 
Therefore, DOE proposed that, for verification and enforcement 
purposes, results of the 10-minute test that are within 2 
percent of the results for the 12-hour test would be deemed to be 
representative of average energy use. 75 FR 75290, 75302-304 (Dec. 2, 
2010); 76 FR 58346, 58349-53 (Sep. 20, 2011).
    The Appliance Standards Awareness Project (ASAP), American Council 
for an Energy Efficient Economy (ACEEE), and National Consumer Law 
Center (NCLC), jointly (hereafter referred to as the ``SNOPR Joint 
Comment''), AHAM, and Whirlpool support the incorporation by reference 
of IEC Standard 62301 (Second Edition). AHAM stated that the Second 
Edition contains important clarifications and would reduce test burden, 
while Whirlpool commented that the Second Edition provides more 
complete mode definitions and more robust measurements. AHAM and the 
SNOPR Joint Comment stated that the Second Edition would allow for 
international harmonization. (AHAM, No. 20 at pp. 1-2; SNOPR Joint 
Comment, No. 22 at p. 1; Whirlpool, No. 21 at p. 2)
    DOE acknowledges the clarity and improvement in the measurement of 
standby mode and off mode power consumption through the use of IEC 
Standard 62301 (Second Edition), as well as the benefits of 
harmonization with international testing methods and the associated 
reduction in test burden for those manufacturers that sell products 
internationally by not requiring multiple standby power tests to be 
conducted according to different testing methods in different 
countries.

[[Page 65949]]

For these reasons, in today's final rule, DOE incorporates by reference 
into the new dishwasher and dehumidifier and amended conventional 
cooking products test procedures the previously noted provisions from 
IEC Standard 62301 (Second Edition), including mode definitions, 
qualified as discussed in section 0 for the specific products, testing 
conditions, equipment, and methodology.
    DOE did not receive comments objecting to the proposed 
incorporation by reference of provisions from IEC Standard 62301 (First 
Edition) for standby mode power measurement for conventional cooking 
products with power consumption that varies as a function of the time 
displayed. DOE determines that the lower test burden for manufacturers 
is not warranted by any potential improved accuracy of the test 
measurement if the Second Edition were to be used. Therefore, DOE 
adopts in today's final rule the average power method from IEC Standard 
62301 (First Edition) for these products.

D. Determination and Classification of Operational Modes

1. Active Mode, Standby Mode, and Off Mode
    As noted previously, EPCA provides definitions of ``active mode,'' 
``standby mode,'' and ``off mode'' (42 U.S.C. 6295(gg)(1)(A)) and 
permits DOE to amend these definitions in the context of a given 
product (42 U.S.C. 6295(gg)(1)(B)).
    EPCA defines ``active mode'' as the condition in which an energy-
using product:
     Is connected to a main power source;
     Has been activated; and
     Provides one or more main functions.

(42 U.S.C. 6295(gg)(1)(A)(i)).
    EPCA defines ``standby mode'' as the condition in which an energy-
using product:
     Is connected to a main power source; and
     Offers one or more of the following user-oriented or 
protective functions:
    [cir] To facilitate the activation or deactivation of other 
functions (including active mode) by remote switch (including remote 
control), internal sensor, or timer;
    [cir] Continuous functions, including information or status 
displays (including clocks) or sensor-based functions.

(42 U.S.C. 6295(gg)(1)(A)(iii)).
    This definition of ``standby mode'' differs from the one provided 
in IEC Standard 62301 (First Edition) by permitting the inclusion of 
multiple standby modes.
    EPCA defines ``off mode'' as the condition in which an energy-using 
product:
     Is connected to a main power source; and
     Is not providing any standby mode or active mode function.

(42 U.S.C. 6295(gg)(1)(A)(ii)).
    In the December 2010 NOPR, DOE discussed that the statutory 
definitions for ``active mode,'' ``standby mode,'' and ``off mode'' 
were developed to be broadly applicable for many energy-using products. 
For specific products with multiple functions, these broad definitions 
could lead to multiple interpretations. Therefore, DOE proposed to 
amend the test procedures to include definitions for these modes based 
on the definitions provided in IEC Standard 62301 (FDIS), with added 
provisions specific to dishwashers, dehumidifiers, and conventional 
cooking products.
a. Active Mode
    In the December 2010 NOPR, DOE proposed the following 
clarifications for the range of main functions that would be classified 
as active mode for each product:
    Dishwashers--``Active mode'' means a mode in which the dishwasher 
is connected to a mains power source, has been activated, and is 
performing the one of the main functions of washing, rinsing, or drying 
(when a drying process is included) dishware, glassware, eating 
utensils, and most cooking utensils by chemical, mechanical and/or 
electrical means, or is involved in functions necessary for these main 
functions, such as admitting water into the dishwasher or pumping water 
out of the dishwasher.
    Conventional Cooking Products--``Active mode'' means a mode in 
which a conventional cooking top, conventional oven, or conventional 
range is connected to a mains power source, has been activated, and is 
performing the main function of producing heat \12\ by means of either 
a gas flame or electric resistance heating.
---------------------------------------------------------------------------

    \12\ In the preamble to the December 2010 NOPR, DOE discussed 
that the main function of producing heat may be used for cooking, 
heating, proofing, or holding the cooking load. Such specificity was 
not included in the proposed regulatory text in appendix I.
---------------------------------------------------------------------------

    Dehumidifiers--``Active mode'' means a mode in which a dehumidifier 
is performing the main functions of removing moisture from ambient air 
by drawing moist air over a refrigerated coil using a fan, circulating 
air through activation of the fan without activation of the 
refrigeration system, or defrosting the refrigerant coil. 75 FR 75290, 
75297-98 (Dec. 2, 2010).
    For the September 2011 SNOPR, DOE's proposal included a revised 
version of the active mode definition in the cooking products test 
procedure, based upon updates adopted by the March 2011 Interim Final 
Rule. Although that rulemaking addressed microwave ovens, the mode 
definitions in the test procedure at appendix I cover all cooking 
products, including microwave ovens and conventional cooking products. 
Therefore, in the September 2011 SNOPR, DOE proposed for cooking 
products that ``active mode means a mode in which the product is 
connected to a mains power source, has been activated, and is 
performing the main function of producing heat by means of a gas flame, 
electric resistance heating, or microwave energy. Delay start mode is a 
one-off, user-initiated, short-duration function that is associated 
with an active mode.'' 76 FR 58346, 58363 (Sep. 20, 2011).
    Northwest Energy Efficiency Alliance (NEEA) agreed with DOE's 
proposed definitions of active mode for each product. (NEEA, No. 11 at 
p. 2) Whirlpool also agreed with DOE's proposed definition of active 
mode for dehumidifiers and conventional cooking products, provided that 
delay start is part of active mode. Whirlpool also agreed with DOE's 
proposed definition of active mode for dishwashers as long as cycle 
finished mode is a part of active mode. (Whirlpool, No. 12 at p. 2) DOE 
evaluates delay start mode and cycle finished mode in the product-
specific discussions in section III.D.2, and notes that the amendments 
adopted in today's final rule provide for measurement of all active 
mode, standby mode, and off mode energy use, including delay start mode 
and cycle finished mode, in the dishwasher, dehumidifier, and 
conventional cooking products test procedures.
    As discussed in sections III.F.2 and III.F.3, DOE further proposed 
in the May 2012 SNOPR that active mode for dishwashers would 
additionally include the functions of circulating air (fan-only mode) 
and regenerating a built-in water softening system. Therefore, DOE 
proposed a revised definition of active mode in the dishwasher test 
procedure that would include these functions. For cooking products, DOE 
proposed that circulating air in fan-only mode would be an active mode 
function, and accordingly proposed to add air circulation to the active 
mode functions. 77 FR 31444, 31447-49, 31462 (May 25, 2012).

[[Page 65950]]

    DOE did not receive comments objecting to the definitions of active 
mode for each of the covered products that were proposed in the May 
2012 SNOPR, Thus, in today's final rule, DOE incoporates in the new 
dishwasher and dehumidifier test procedures and the amendments to the 
conventional cooking product test procedure the definition of active 
mode as proposed in the May 2012 SNOPR.
b. Standby Mode
    DOE also proposed in the December 2010 NOPR to define ``standby 
mode'' for dishwashers, dehumidifiers, and conventional cooking 
products as any mode in which the product is connected to a mains power 
source and offers one or more of the following user-oriented or 
protective functions which may persist for an indefinite time:
     To facilitate the activation of other modes (including 
activation or deactivation of active mode) by remote switch (including 
remote control), internal sensor, or timer;
     Continuous functions, including information or status 
displays (including clocks) or sensor-based functions. 75 FR 75290, 
75290 (Dec. 2, 2010).
    In the December 2010 NOPR, DOE also proposed the additional 
clarification that a timer is a continuous clock function (which may or 
may not be associated with a display) that provides regular scheduled 
tasks (e.g., switching) and that operates on a continuous basis. Id.
    AHAM stated that it supported the standby mode definition based on 
IEC Standard 62301 (FDIS), although IEC Standard 62301 (Second Edition) 
should be the basis for the definition once the Second Edition was 
issued. AHAM and Whirlpool also requested that DOE require that all 
products default to the standby mode, as delivered from the factory. 
(AHAM, No. 14 at p. 3; AHAM, NOPR Public Meeting Transcript, No. 10 at 
p. 36; Whirlpool, No. 12 at pp. 2, 4) DOE notes that its test 
procedures are used to measure the energy consumption of covered 
products in active, standby, and off modes, and do not prescribe 
specific operational characteristics for those products.
    DOE proposed in the December 2010 NOPR to amend the ``standby 
mode'' definition in the dishwasher test procedure based on the 
definition provided in IEC Standard 62301 (FDIS), but also proposed to 
retain and redesignate the current DOE definition of standby mode for 
dishwashers as a ``simplified standby mode'' to allow manufacturers to 
continue to use the existing standby mode provisions to determine 
compliance with the current dishwasher energy conservation standards 
until the compliance date of amended standards that address standby 
mode and off mode energy use. Id.
    Whirlpool commented that the retention of a simplified standby mode 
as a bridging step from the current DOE dishwasher test procedure is 
unnecessary. (Whirlpool, No. 12 at p. 2) In this final rule, DOE is 
retaining the existing methodology for measuring energy use in this 
``simplified standby mode'' in appendix C. Use of the new standby mode 
provisions in appendix C1 will be required on May 30, 2013, unless the 
direct final rule published on May 30, 2012 is withdrawn.
    In the December 2010 NOPR, DOE proposed to define ``inactive mode'' 
for dishwashers, dehumidifiers, and conventional cooking products as a 
standby mode that facilitates the activation of active mode by remote 
switch (including remote control), internal sensor, or timer, or that 
provides continuous status display. Id.
    AHAM and NEEA supported DOE's proposed definition of inactive mode. 
(AHAM, No. 14 at p. 4; NEEA, No. 11 at p. 3) For the December 2010 
NOPR, DOE derived the proposed mode definitions from IEC Standard 62301 
(FDIS), which were retained for IEC Standard 62301 (Second Edition). 
DOE retains this definition of inactive mode in this final rule.
c. Off Mode
    In the December 2010 NOPR, DOE also proposed to amend the test 
procedures for residential dishwashers, dehumidifiers, and conventional 
cooking products to define ``off mode'' as a mode in which the product 
is connected to a mains power source and is not providing any active 
mode or standby mode function, and where the mode may persist for an 
indefinite time. An indicator that shows the user only that the product 
is in the off positions would be included within the classification of 
off mode. This definition of ``off mode'' was based on the definitions 
provided in IEC Standard 62301 (FDIS), and DOE stated that it would be 
useful in terms of expanding the scope of the EPCA mode definitions to 
clarify which functions are associated with off mode. 75 FR 75290, 
75299 (Dec. 2, 2010).
    Under these proposed definitions, a dishwasher, dehumidifier, or 
conventional cooking product equipped with a mechanical on/off switch 
that can disconnect power to the display and/or control components 
would be considered as operating in the off mode when the switch is in 
the ``off'' position, provided that no other standby mode or active 
mode functions are energized. An energized light-emitting diode (LED) 
or other indication that shows the user only that the product is in the 
off position would be considered part of off mode under the proposed 
definition, again provided that no other standby mode or active mode 
functions are energized. However, if any energy is consumed by the 
appliance in the presence of a one-way remote control, the unit would 
be considered to be operating in standby mode because the remote 
control would be used to activate or deactivate other mode(s). 
Electrical leakage and any energy consumed for electrical noise 
reduction, which are not specifically categorized as standby power 
functions, would be considered part of off mode. Id.
    NEEA supports the proposed definition of off mode for dishwashers, 
dehumidifiers, and conventional cooking products, to the extent that it 
is consistent with IEC Standard 62301. (NEEA, No. 11 at pp. 4-5) 
Whirlpool stated that the EPCA definition of off mode is adequate for 
each of these products. (AHAM, No. 12 at pp. 2-3) DOE determined that 
the definition of off mode that is consistent with the definition in 
IEC Standard 62301 (Second Edition) is an important expansion to the 
EPCA definition that provides clarity for testing, and adopts in 
today's final rule the proposed definition of off mode for the new 
dishwasher and dehumidifier test procedures and the amended 
conventional cooking products test procedure.
    AHAM and Whirlpool do not support classifying the energy use of a 
one-way remote control as part of standby mode, even though the EPCA 
definition of standby mode includes activation by means of remote 
control. According to these commenters, a standard remote that powers a 
product ``off'' actually powers the unit down, such that it can be 
turned on again through the use of the remote. A one-way remote does 
not put the product in standby mode; it only allows the product to be 
turned off. AHAM commented that there are few, if any, one-way remotes 
in the United States. AHAM believes that including one-way remotes in 
off mode instead of standby mode will encourage manufacturers to design 
products with one-way remotes, which could decrease energy use. (AHAM, 
No. 14 at p. 4; Whirlpool, No. 12 at p. 3) DOE agrees that once the 
one-way remote turns the product off, such that there is no standby 
function present and the unit cannot be returned to either active or 
standby mode by means of the remote,

[[Page 65951]]

the unit would be considered to be operating in off mode. However, if 
the product is consuming energy without being in active mode while 
waiting for a signal from the one-way remote, the product would be 
classified as operating in standby mode because the remote would be 
available for deactivation of the main unit, regardless of whether 
other standby functions were present. Therefore, DOE clarifies that if 
energy is consumed by the appliance in the presence of a one-way remote 
control prior to turning the unit off from a non-active mode, the unit 
would be considered to be operating in standby mode because the remote 
control would be used to deactivate other mode(s). Once the product is 
turned off by the one-way remote, it would be deemed to be operating in 
either standby mode or off mode, depending on the functions present in 
the appliance other than the remote control function, because the one-
way remote would not be able to activate or deactivate other mode(s) at 
that point.
2. Additional Product-Specific Modes
    In addition to the general mode definitions, DOE discussed in the 
December 2010 NOPR its analysis of various product-specific modes for 
dishwashers, dehumidifiers, and conventional cooking products to 
determine whether they would be properly characterized as active mode, 
standby mode, or off mode functions, as follows:
a. Dishwashers
    In the December 2010 NOPR, DOE stated that it is aware of two 
additional relevant modes for dishwashers: (1) Delay start mode; and 
(2) cycle finished mode. ``Delay start mode'' would be defined as a 
mode in which activation of an active mode is facilitated by a timer. 
``Cycle finished mode'' would be defined as a mode that provides 
continuous status display following operation in active mode.
    As discussed earlier, because delay start mode is not a mode that 
may persist for an indefinite time, delay start mode would not be 
considered part of standby mode, but instead would be a form of active 
mode. DOE did not propose amendments to the dishwasher test procedure 
to define ``delay start mode'' or to measure power consumption in this 
mode. DOE stated that it may consider amendments addressing delay start 
mode issues in a future dishwasher test procedure rulemaking. 75 FR 
75290, 75298 (Dec. 2, 2010).
    Based on the ``standby mode'' definition proposed in the December 
2010 NOPR, cycle finished mode, which provides a continuous status 
display and may persist for an indefinite time, would be considered as 
part of a standby mode. Therefore, DOE proposed in the December 2010 
NOPR to define cycle finished mode for dishwashers as ``a mode which 
provides continuous status display following operation in active 
mode.'' Id. For the May 2012 SNOPR, DOE also identified fan-only mode 
for dishwashers (77 FR 31444, 31447-49 (May 25, 2012)), which is 
discussed separately in section III.F.2 of this notice, as well as 
dishwasher water softener regeneration (77 FR 31444, 31449-50 (May 25, 
2012)), which is discussed in section III.F.3 of this notice.
    ASAP, ACEEE, NCLC, and Natural Resources Defense Council (NRDC), 
jointly (hereafter referred to as the ``NOPR/SNOPR2 Joint Comment''), 
Southern California Edison, Southern California Gas Company, and San 
Diego Gas and Electric Company, jointly (hereafter the ``California 
Utilities''), AHAM, NEEA, Pacific Gas and Electric Company (PG&E), and 
Whirlpool agree with DOE's proposal that delay start mode should be 
classified as a form of active mode. AHAM supported DOE's decision not 
to propose amendments to the dishwasher test procedure to measure 
energy use in delay start mode, while the California Utilities, the 
NOPR/SNOPR2 Joint Comment, and PG&E stated that DOE should include 
measures of delay start mode energy use in the dishwasher test 
procedure. The NOPR/SNOPR2 Joint Comment believes that if energy 
consumption in delay start mode is not measured, manufacturers will 
have no incentive to reduce it. (AHAM, No. 14 at p. 5; AHAM, NOPR 
Public Meeting Transcript, No. 10 at p. 41; California Utilities, No. 
16 at p. 2; NEEA, No. 11 at p. 2; NOPR/SNOPR2 Joint Comment, No. 13 at 
pp. 2-3; PG&E, No. 17 at p. 2; Whirlpool, No. 12 at p. 2) DOE retains 
the classification of delay start mode as part of active mode for 
dishwashers in today's final rule. Although DOE is not adopting 
specific provisions to measure energy use in delay start mode alone, 
DOE is including provisions in the dishwasher test procedure at 
appendix C1 to measure the energy use in all low-power modes combined, 
which includes modes other than the active washing and drying cycle, 
fan-only mode, and water softener regeneration. (See section III.F.1).
    AHAM and Whirlpool disagree with DOE's proposal to classify cycle 
finished mode for dishwashers as a standby mode. According to 
Whirlpool, any function begun by the user when initiating the active 
mode includes all power consumed until the full conclusion of that 
operation. Whirlpool stated that cycle-finished mode actions include 
vent opening/closing, a signal to the consumer that the dishes are 
clean, or other modest users of energy. Whirlpool believes that 
establishing a separate cycle finished mode adds complications and cost 
to the dishwasher test procedure without any corresponding improvement 
in energy consumption or value to the consumer. (AHAM, No. 14 at p. 5; 
AHAM, NOPR Public Meeting Transcript, No. 10 at pp. 41-42; Whirlpool, 
No. 12 at p. 2) NEEA stated that DOE should define cycle finished mode 
as the portion of the active mode between the end of the active washing 
mode and the beginning of the inactive mode. However, NEEA interpreted 
cycle finished mode to mean the period in which a fan operates after 
the end of the active washing and drying cycle. NEEA noted that after 
the fan run time, the dishwasher reverts to a status display (inactive) 
mode that will persist indefinitely until the user opens the door. NEEA 
believes that the status display (inactive) mode is a standby mode. 
NEEA further commented that if DOE defines such a status display mode 
as ``cycle finished mode,'' that the cycle finished period of some 
specified average duration should be added to the active mode test 
procedure. (NEEA, No. 11 at pp. 2-3)
    DOE notes that in its proposals, it narrowly defined cycle finished 
mode for dishwashers as providing continuous status display following 
operation in active mode. Because the function specified in this 
definition is a status display that may persist for an indefinite time 
until the user opens the door, cycle finished mode for dishwashers 
would be classified as a standby mode under the general definition of 
``standby mode'' adopted in today's final rule for the new dishwasher 
test procedure. DOE has also determined that any period of fan 
operation after the end of the active washing and drying cycle would be 
classified as a ``fan-only mode'' that is part of active mode. As 
discussed in section III.F.2 of today's final rule, DOE includes in the 
new dishwasher test procedure provisions to measure the energy use in 
fan-only mode if the dishwasher is capable of such operation. In 
today's final rule, DOE also adds definitions of cycle finished mode 
and fan-only mode to the dishwasher test procedure to aid the tester in 
differentiating these modes and to clarify that the energy use in cycle 
finished mode is included in the

[[Page 65952]]

combined low-power energy use measurement, as discussed in section 
III.F.1 of this notice.
b. Dehumidifiers
    In the December 2010 NOPR, DOE stated that it is aware of three 
additional relevant modes for dehumidifiers: (1) Delay start mode; (2) 
off-cycle mode; and (3) bucket full/removed mode. DOE proposed that the 
definition for ``delay start mode'' for dehumidifiers would be the same 
as that for dishwashers. ``Off-cycle mode'' would be defined as a mode 
in which a dehumidifier has cycled off its main function by humidistat 
or humidity sensor, does not have its fan or blower operating, and will 
reactivate the main function according to the humidistat or humidity 
sensor signal. ``Bucket full/removed mode'' would be defined as a mode 
in which the dehumidifier has automatically powered off its main 
function by detecting when the water collection bucket is full or has 
been removed.
    For the same reasons discussed earlier for dishwashers, delay start 
mode would not be considered a standby mode, but instead would be a 
form of active mode. DOE did not propose in the December 2010 NOPR 
amendments to define or to measure power consumption in delay start 
mode. DOE stated that it may consider amendments addressing delay start 
mode issues in a future dehumidifier test procedure rulemaking. 75 FR 
75290, 75298 (Dec. 2, 2010).
    DOE discussed in the December 2010 NOPR that off-cycle mode and 
bucket full/removed mode are modes that may persist for an indefinite 
time and, under the proposed definition, would be considered as part of 
standby mode. DOE proposed amending its dehumidifier test procedure to 
include definitions of ``off-cycle mode'' and ``bucket full/removed 
mode.'' 75290, 75298-99 (Dec. 2, 2010).
    The NOPR/SNOPR2 Joint Comment, the California Utilities, AHAM, 
NEEA, PG&E, and Whirlpool agree with DOE's proposal that delay start 
mode should be classified as a form of active mode for dehumidifiers. 
AHAM supported DOE's decision not to propose amendments to the 
dehumidifier test procedure to measure energy use in delay start mode. 
The California Utilities, the NOPR/SNOPR2 Joint Comment, and PG&E 
stated that DOE should include measures of delay start mode energy use 
in the dehumidifier test procedure. The NOPR/SNOPR2 Joint Comment 
stated that if energy consumption in delay start mode is not measured, 
manufacturers will have no incentive to reduce it. (AHAM, No. 14 at p. 
5; AHAM, NOPR Public Meeting Transcript, No. 10 at p. 45; California 
Utilities, No. 16 at p. 2; NEEA, No. 11 at p. 2; NOPR/SNOPR2 Joint 
Comment, No. 13 at pp. 2-3; PG&E, No. 17 at p. 2; Whirlpool, No. 12 at 
p. 2) DOE maintains this determination that delay start mode is part of 
active mode for dehumidifiers in today's final rule. DOE includes 
provisions in the new dehumidifier test procedure to measure the energy 
use in all low-power modes combined, which includes all modes other 
than active dehumidification mode (i.e., delay start mode, bucket full/
removed mode, inactive mode, off-cycle mode, and off mode.) (See 
section III.F.1).
    Several commenters objected to DOE's proposed classification of 
bucket full/removed mode as a standby mode. GE Consumer & Industrial 
(GE) and NEEA consider bucket full/removed mode as a cycle finished 
mode, and while it may persist for an indefinite period of time, it is 
associated with the active mode cycle, much like the dishwasher cycle 
finished mode. NEEA further stated that DOE should consider bucket 
full/removed mode as the portion of the active mode between the end of 
the active cycle and the beginning of the inactive mode when the user 
empties and/or replaces the bucket. (GE, NOPR Public Meeting 
Transcript, No. 10 at p. 45; NEEA, No. 11 at pp. 3-4) Whirlpool and 
AHAM also consider bucket full/removed mode to be part of active mode. 
(Whirlpool, No. 12 at p. 2; AHAM, No. 14 at p. 5) However, in the event 
that DOE retains bucket full/removed mode as a standby mode, AHAM 
suggested that the definition of bucket full/removed mode should 
clarify that the dehumidifier has automatically powered off its main 
function by detecting when the water bucket is full or has been 
removed, and does not have its fan or blower operating. (AHAM, No. 14 
at p. 5)
    DOE agrees that the bucket full/removed mode can be associated with 
the active mode function in which moisture is removed from the air and 
collected in the bucket. However, bucket full/removed mode can also 
occur when the bucket is removed, regardless of whether the 
dehumidifier was actively removing moisture or circulating air at the 
time the bucket was removed. For example, the bucket may be removed 
during off-cycle mode, which is a standby mode. In addition, bucket 
full/removed mode may persist indefinitely with a continuous status 
display and no main function, which would meet the definition of a 
standby mode. DOE maintains its determination that bucket full/removed 
mode is a standby mode for today's final rule. DOE agrees that the fan 
or blower shall not be operating during bucket full/removed mode, 
because such operation would result in the dehumidifier circulating air 
as part of active mode, but does not adopt a definition of bucket full/
removed mode in the new dehumidifier test procedure because bucket 
full/removed mode energy use is included in the combined measurement of 
all low-power mode energy use.
    Whirlpool agreed with DOE's proposal to classify off-cycle mode as 
a standby mode. (Whirlpool, No. 12 at p. 2) In today's final rule, DOE 
includes the proposed definition of off-cycle mode in appendix X1, and 
includes off-cycle mode in the measurement of energy use in the 
combined low-power modes.
c. Conventional Cooking Products
    DOE stated in the December 2010 NOPR that it is aware of three 
additional relevant modes for conventional cooking products: (1) Delay 
start mode; (2) cycle finished mode; and (3) Sabbath mode. ``Delay 
start mode'' and ``cycle finished mode'' would be the same as defined 
for dishwashers. ``Sabbath mode'' would be defined as a mode in which 
the automatic shutoff is overridden to allow for warming of pre-cooked 
foods during such periods as the Jewish Sabbath.
    For the same reasons as discussed for dishwashers and 
dehumidifiers, delay start mode would not be considered a standby mode, 
but instead would be a form of active mode. In addition, the Sabbath 
mode function of warming food would also be considered part of the 
active mode. DOE did not propose in the December 2010 NOPR amendments 
to define or to measure power consumption in ``delay start mode'' or 
``Sabbath mode.'' DOE stated that it may consider amendments addressing 
delay start mode and Sabbath mode issues in a future cooking products 
test procedure rulemaking 75 FR 75290, 75299 (Dec. 2, 2010).
    DOE discussed in the December 2010 NOPR that cycle finished mode is 
a mode that may persist for an indefinite time and, under the proposed 
definition, would be considered as part of standby mode. DOE proposed 
to amend its conventional cooking products test procedure to include a 
definition of ``cycle finished mode.'' 75 FR 75290, 75299 (Dec. 2, 
2010). For the May 2012 SNOPR, DOE also identified fan-only mode for 
conventional cooking products, which is discussed in section III.F.2 of 
this notice.
    The NOPR/SNOPR2 Joint Comment, the California Utilities, AHAM, 
NEEA, PG&E, and Whirlpool commented that

[[Page 65953]]

delay start mode should be considered part of active mode for 
conventional cooking products. The California Utilities, the NOPR/
SNOPR2 Joint Comment, and PG&E stated that DOE should include measures 
of delay start mode energy use in the test procedure. The NOPR/SNOPR2 
Joint Comment believes that if energy consumption in delay start mode 
is not measured, manufacturers will have no incentive to reduce it. 
(AHAM, No. 14 at p. 5; AHAM, NOPR Public Meeting Transcript, No. 10 at 
p. 46; California Utilities, No. 16 at p. 2; NEEA, No. 11 at p. 2, 
NOPR/SNOPR2 Joint Comment, No. 13 at pp. 2-3; PG&E, No. 17 at p. 2; 
Whirlpool, No. 12 at p. 2) NEEA and Whirlpool also agree with DOE that 
Sabbath mode is part of active mode. (NEEA, No. 11 at p. 4; Whirlpool, 
No. 12 at p. 3)
    For the reasons discussed in section III.F.1 of this notice, DOE 
amends the cooking products test procedure to add provisions for 
measuring the combined low-power energy use, which will account for all 
energy use outside of the active cooking cycle \13\ and fan-only mode.
---------------------------------------------------------------------------

    \13\ In the December 2010, DOE proposed to allocate the 8.9 
estimated annual Sabbath mode hours to the active cooking mode. 75 
FR 75290, 75309-10 (Dec. 2, 2010).
---------------------------------------------------------------------------

    AHAM and Whirlpool disagree with DOE's proposal to classify cycle 
finished mode for conventional cooking products as a standby mode. 
According to Whirlpool, any function begun by the user when initiating 
the active mode includes all power consumed until the full conclusion 
of that operation. Whirlpool believes that establishing a separate 
cycle finished mode adds complications and cost to the conventional 
cooking products test procedure without any corresponding improvement 
in energy consumption or value to the consumer. (AHAM, No. 14 at p. 5; 
AHAM, NOPR Public Meeting Transcript, No. 10 at pp. 46-47; Whirlpool, 
No. 12 at pp. 2-3) NEEA stated that operation of the cooling fan that 
protects the electronic controls comprises cycle finished mode, with 
its duration being directly related to the temperature at which the 
active cooking function was conducted. According to NEEA, DOE should 
define cycle finished mode as the portion of the active mode between 
the end of the active cooking mode and the beginning of the inactive 
mode, when the cooling fan stops. (NEEA, No. 11 at pp. 2-4)
    As with dishwashers, DOE's proposals narrowly defined cycle 
finished mode for conventional cooking products as providing continuous 
status display following operation in active mode. Because the function 
specified in this definition is a status display that may persist for 
an indefinite time until the user takes action, cycle finished mode for 
conventional cooking products would be classified as a standby mode 
under the general definition of ``standby mode'' adopted in today's 
final rule for the conventional cooking products test procedure. DOE 
has also determined that any period of fan operation after the end of 
the active cooking cycle would be classified as a ``fan-only mode'' 
that is part of active mode. As discussed in section III.F.2 of today's 
final rule, DOE includes in its amendments to the cooking products test 
procedure provisions to measure the energy use in fan-only mode if the 
conventional cooking product is capable of such operation. In today's 
final rule, DOE also adds definitions of cycle finished mode and fan-
only mode to the cooking products test procedure.
3. Network Mode
    Section 3.7 of IEC Standard 62301 (FDIS) defines ``network mode'' 
as a mode category that includes ``any product modes where the energy 
using product is connected to a mains power source and at least one 
network function is activated (such as reactivation via network command 
or network integrity communication) but where the primary function is 
not active.'' Section 3.7 of IEC Standard 62301 (FDIS) also provides a 
note, stating that ``[w]here a network function is provided but is not 
active and/or not connected to a network, then this mode is not 
applicable. A network function could become active intermittently 
according to a fixed schedule or in response to a network requirement. 
A `network' in this context includes communication between two or more 
separately independently powered devices or products. A network does 
not include one or more controls which are dedicated to a single 
product. Network mode may include one or more standby functions.''
    DOE acknowledged in the December 2010 NOPR that in the future, 
products that are the subject of this rulemaking could incorporate a 
network mode for either communication with technicians for repair and 
performance monitoring, or for interaction with the electric grid. At 
the time of the December 2010 NOPR, however, DOE was unaware of any 
data that would enable it to determine appropriate testing procedures 
and mode definitions for incorporation into test procedures for network 
mode in dishwashers, dehumidifiers, and conventional cooking products. 
As a result, DOE could not evaluate networked units, even in terms of 
categorizing network mode as a standby mode or off mode function. In 
particular, DOE was unaware of methods for appropriately configuring 
networks or methods for collecting data about the energy use of 
appropriately configured networks. DOE also had no information as to 
whether network connection speed or the number and type of network 
connections affect power consumption for these products. DOE also had 
no information as to whether wireless network devices in such products 
would have different levels of power consumption when a device is 
establishing a connection versus when the network connection is 
established. DOE stated in the December 2010 NOPR that it was also 
unaware of how the energy consumption for dishwashers, dehumidifiers, 
and conventional cooking products in a network environment may be 
affected by their product design and user interaction, as well as 
network interaction. These effects would need to be measured if the 
network function could become active intermittently according to a 
fixed schedule or in response to a network requirement. For these 
reasons, the amendments proposed in the December 2010 NOPR did not 
include provisions for testing network mode energy consumption in 
dishwashers, dehumidifiers, and conventional cooking products. DOE 
noted that provisions for testing power consumption in network mode 
could be incorporated into the test procedure through future amendments 
once the appropriate data and testing methodologies become available. 
75 FR 75290, 75299 (Dec. 2, 2010).
    AHAM and Whirlpool agreed with DOE that there are no dishwashers, 
dehumidifiers, or conventional cooking products on the market currently 
that are capable of operation in network mode, and that there is no way 
for DOE to gather data on this mode. Thus, these commenters agreed with 
DOE's proposal not to address network mode until such time that 
sufficient data are available. AHAM and Whirlpool also stated that 
network mode would be distinct from standby or off mode. (AHAM, No. 14 
at p. 6; AHAM, NOPR Public Meeting Transcript, No. 10 at pp. 48, 50; 
Whirlpool, No. 12 at p. 4)
    The NOPR/SNOPR2 Joint Comment, the California Utilities, ASAP, 
NEEA, and PG&E urged DOE to develop test methodology for network mode. 
According to these commenters, a number of major manufacturers are 
developing network-enabled

[[Page 65954]]

dishwashers and cooking products, and these products are expected to be 
available on the market when the amended test procedures become 
effective. Further, these commenters stated that products with network 
capability may consume significant energy in network mode. ASAP and the 
NOPR/SNOPR2 Joint Comment stated that the energy use in network mode 
should be captured regardless of whether the product is actually 
connected to a network. NEEA noted that IEC Standard 62301 defines 
network mode as part of inactive mode, and that DOE should adopt a 
definition of network mode consistent with the one in IEC Standard 
62301, along with methodology to measure network mode energy use during 
inactive mode testing. The SNOPR Joint Comment stated that the 
definition of standby mode is sufficiently broad to encompass energy 
use in network mode. (ASAP, NOPR Public Meeting Transcript, No. 10 at 
pp. 49-50; California Utilities, No. 16 at p. 3; NOPR/SNOPR2 Joint 
Comment, No. 13 at pp. 3-4; SNOPR Joint Comment, No. 22 at p. 1; NEEA, 
No. 11 at pp. 4-5; PG&E, No. 17 at p. 3)
    In response to these comments, DOE observes that it is still not 
aware of any network-equipped dishwashers, dehumidifiers, and 
conventional cooking products that could allow sufficient analysis on 
which to categorize the functionality of network mode in these 
products, nor did commenters provide information or data on which to 
develop test methodology for measuring energy use in a network mode. 
Therefore, for the same reasons that DOE did not address network mode 
in the December 2010 NOPR, DOE is not adopting a definition or testing 
methodology for network mode in the dishwasher, dehumidifier, or 
conventional cooking products test procedures in today's final rule. 
DOE reiterates, however, that it may consider amending these test 
procedures in a separate rulemaking in the future should network-
equipped products and data on their functionality become available.
4. Disconnected Mode
    DOE also noted in the December 2010 NOPR that section 3.9 of IEC 
Standard 62301 (FDIS) provides a definition for ``disconnected mode,'' 
which is ``the state where all connections to mains power sources of 
the energy using product are removed or interrupted.'' IEC Standard 
62301 (FDIS) also adds a note that common terms such as ``unplugged'' 
or ``cut off from mains'' also describe this mode and that this mode is 
not part of off mode, standby mode, or network mode. DOE stated in the 
December 2010 NOPR that there would be no energy use in a disconnected 
mode and agreed that it would not be part of off mode, standby mode, or 
network mode. Therefore, DOE did not propose a definition or testing 
method for disconnected mode in the test procedures for residential 
dishwashers, dehumidifiers, or conventional cooking products. 75 FR 
75290, 75299-300 (Dec. 2, 2010).
    AHAM agreed that there would be no energy use in disconnected mode, 
and supported DOE's decision not to amend the test procedures 
accordingly. (AHAM, No. 14 at p. 4) In consideration of this support 
and for the reasons discussed above, DOE does not amend the dishwasher, 
dehumidifier, and conventional cooking products test procedures to 
define or add testing provisions for disconnected mode in today's final 
rule.

E. Specifications for the Test Methods and Measurements for Standby 
Mode and Off Mode Testing

    As discussed in section III.C of this notice, DOE proposed in the 
December 2010 NOPR to specify testing equipment and conditions for 
measuring standby mode and off mode energy use in the dishwasher, 
dehumidifier, and conventional cooking products test procedures, based 
on provisions in IEC Standard 62301 (First Edition). 75 FR 75290, 
75300-04 (Dec. 2, 2010). In September 2011 SNOPR, it proposed to 
incorporate by reference in the dishwasher, dehumidifier, and 
conventional cooking products test procedures the following provisions 
from IEC Standard 62301 (Second Edition) for testing equipment and 
conditions: (1) The room ambient air temperature requirements in 
section 4, paragraph 4.2; (2) the electrical supply voltage 
requirements in section 4, paragraph 4.3.2; (3) the power equipment 
specifications in section 4, paragraph 4.4; (4) the instructions for 
allowing the product to enter a lower power state prior to the test 
measurement in section 5, paragraph 5.1, note 1; and (5) portions of 
the installation and setup procedures in section 5, paragraph 5.2. 76 
FR 58436, 58349-54 (Sep. 20, 2011).
1. Ambient Conditions, Including for Active Mode
    In the December 2010 NOPR, DOE proposed that test room ambient 
temperatures for standby mode and off mode testing be specified for all 
dishwashers, dehumidifiers, and conventional cooking products according 
to section 4, paragraph 4.2 of IEC Standard 62301 (First Edition). 75 
FR 75290, 75301-02 (Dec. 2, 2010). The First Edition specified a 
temperature range of 73.4  9[emsp14][deg]F. Section 4, 
paragraph 4.2 of IEC Standard 62301 (Second Edition) contains an 
identical requirement for the test room ambient temperature, which DOE 
proposed to reference for standby mode and off mode testing in the 
September 2011 SNOPR. In the December 2010 NOPR, DOE also compared the 
IEC Standard 62301 (First Edition) ambient temperature ranges to those 
specified in the current DOE dishwasher, dehumidifier, and conventional 
cooking products test procedures for active mode testing as follows. 
Because the same IEC ambient temperatures were specified in the Second 
Edition, DOE drew the same tentative conclusions in the September 2011 
SNOPR.
    DOE noted in the December 2010 NOPR that the current DOE test 
procedure for dishwashers includes a test room ambient air temperature 
requirement of 75  5 [deg]F, which helps ensure consistent 
and repeatable test results for active mode measurements in which heat 
losses could affect energy consumption. Because energy use in standby 
mode or off mode is less affected by ambient temperature than active 
mode energy use, DOE proposed to allow manufacturers of dishwashers to 
use the less stringent ambient temperature range in IEC Standard 62301 
(First Edition) for standby mode and off mode power consumption 
measurement. DOE further stated that manufacturers could choose to use 
the ambient temperature range in the current DOE test procedure if 
tests of active mode efficiency performance and standby mode and off 
mode power consumption are conducted simultaneously in the same room on 
multiple dishwashers. 75 FR 75290, 75301 (Dec. 2, 2010).
    For dehumidifiers, the current DOE test procedure specifies a test 
room ambient temperature of 80  2 [deg]F. As with 
dishwashers, DOE's proposal in the December 2010 NOPR would allow 
manufacturers of dehumidifiers to conduct active mode efficiency 
performance testing and standby mode and off mode power consumption 
testing simultaneously in the same room on multiple dehumidifiers, as 
long as the temperature requirements for both tests are met. 
Alternatively, the proposed temperature specifications taken from IEC 
Standard 62301 (First Edition) would allow a manufacturer that opts to 
conduct standby mode and off mode testing separately from performance 
testing to use the ambient

[[Page 65955]]

temperature requirement of 73.4  9 [deg]F. 75 FR 75290, 
75301 (Dec. 2, 2010).
    The current DOE test procedure for conventional cooking products 
includes a test room ambient air temperature specification of 77  9 [deg]F, which varies slightly from the range specified by IEC 
Standard 62301 of 73.4  9 [deg]F. DOE stated in the 
December 2010 NOPR that the higher temperatures allowed for active mode 
energy testing could be representative of ambient temperatures during a 
cooking process, but that maintaining lower allowable temperatures for 
standby mode and off mode power consumption measurements would be more 
representative of ambient conditions during those operating modes. The 
proposed test procedure would allow manufacturers of conventional 
cooking products to measure active mode performance and standby and off 
mode power simultaneously in the same room on multiple units, provided 
that the room ambient temperature falls within the range allowed by 
both ambient temperature requirements (i.e., any temperature between 68 
and 82.4 [deg]F). Alternatively, the proposal would allow a 
manufacturer to conduct standby mode and off mode testing separately 
from performance testing within an ambient temperature range of 73.4 
 9 [deg]F. 75 FR 75290, 75301-02 (Dec. 2, 2010).
    AHAM stated that DOE should use the ambient temperature 
requirements in its current dishwasher, dehumidifier, and conventional 
cooking products test procedures for standby mode and off mode energy 
use measurements, which AHAM stated would produce accurate, repeatable, 
and reproducible results. AHAM and Whirlpool noted that the DOE 
temperature requirements are more stringent for dishwashers and 
dehumidifiers, and that DOE's ambient temperature requirements in the 
cooking products test procedure substantially overlaps with the IEC 
temperature range. For the same reasons as AHAM outlined, BSH commented 
that the more stringent DOE ambient temperature requirements in the 
dishwasher test procedure should apply for standby mode and off mode 
testing. (AHAM, No. 14 at pp. 7-8; AHAM, No. 27 at p. 12; AHAM, NOPR 
Public Meeting Transcript, No. 10 at p. 63; BSH, No. 28 at pp. 9-10; 
Whirlpool, No. 26 at p. 1) AHAM, BSH, and Whirlpool suggested a single 
temperature range would reduce inadvertent testing error. Whirlpool 
recommended more stringent ambient room temperatures for the dishwasher 
and conventional cooking products test procedures for all testing--75 
 2 [deg]F for dishwashers and 75  5 [deg]F for 
conventional cooking products--and supported conducting all 
dehumidifier testing under the current DOE active mode test conditions 
of 80  2 [deg]F. According to Whirlpool, a 1 [deg]F 
difference in ambient temperature can cause a 1.5 kWh change in the 
measurement of dishwasher annual energy use. AHAM stated that not every 
laboratory could achieve a tolerance tighter than  5 [deg]F 
for dishwasher testing. (AHAM, No. 14 at pp. 7-8; AHAM, No. 27 at p. 
12; AHAM, 2012 Public Meeting Transcript, No. 38 at pp. 152-153; BSH, 
No. 28 at pp. 9-10; Whirlpool, No. 12 at pp. 4-5; Whirlpool, No. 21 at 
p. 3; Whirlpool, No. 26 at pp. 1, 5) AHAM, BSH, and Whirlpool also 
stated that the dishwasher test procedure should clarify that the 
tolerances specified indicate the allowable limits of variation in 
temperature, but do not permit the deliberate variation with those 
limits. (AHAM, No. 27 at p. 12; AHAM, 2012 Public Meeting Transcript, 
No. 38 at p. 151; BSH, No. 28 at p. 10; Whirlpool, No. 26 at p. 1; 
Whirlpool, 2012 Public Meeting Transcript, No. 38 at pp. 153-154) 
Intertek noted that it understood that the intent of the dishwasher 
test procedure is to target 75 [deg]F, and they aim to maintain this 
ambient temperature. According to Intertek, it is also important to 
maintain this temperature prior to conducting the test when the soils 
are drying on the test load. (Intertek, 2012 Public Meeting Transcript, 
No. 38 at pp. 154-155)
    In the August 2012 SNOPR, DOE maintained its proposals that the 
standby mode and off mode testing for dishwashers, dehumidifiers, and 
conventional cooking products be allowed to be conducted under either 
the ambient temperature range specified in IEC Standard 62301 (Second 
Edition) or the ambient temperature range specified in the DOE test 
procedure where the DOE active mode temperature range overlaps the IEC 
temperature range. DOE re-examined this issue in light of the comments 
received. DOE confirmed its proposed approach to not require that 
standby mode and off mode testing be conducted under the same ambient 
temperature as active mode testing because no data were available to 
suggest that the standby mode and off mode power of residential 
dishwashers varies significantly within the allowable ambient 
temperature range of IEC Standard 62301 (Second Edition), and because 
this approach would increase the burden for those manufacturers or 
laboratories that choose to conduct standby mode and off mode testing 
separately from active mode testing. 77 FR 49064, 49066 (Aug. 15, 2012)
    In the August 2012 SNOPR, DOE also responded to comments on the 
intent of the ambient temperature range in the dishwasher test 
procedure by noting that the tolerances specified in the DOE test 
procedures provide a range of temperatures under which the test results 
are considered valid, regardless of the reasons for why a particular 
temperature within the range was selected or achieved. Therefore, DOE 
did not alter its proposal to state that the dishwasher test should be 
conducted at the nominal center of the ambient temperature range. DOE 
stated that it recognized the impact of ambient temperature on the 
active mode measurement, however, and as an alternative to the 5 [deg]F tolerance in the current test procedure for active mode 
testing, DOE proposed to tighten the tolerance on the test room ambient 
temperature in the dishwasher test procedure to 2 [deg]F 
for active mode testing. Id.
    DOE did not receive comments in response to the August 2012 SNOPR 
on the proposal that the standby mode and off mode testing for 
dishwashers, dehumidifiers, and conventional cooking products may be 
conducted within the range of ambient temperatures where the specified 
temperature ranges of IEC Standard 62301 (Second Edition) and the DOE 
test procedure overlap if the testing laboratory chooses to conduct 
standby mode and off mode testing in the same facility as for active 
mode testing. DOE acknowledges the previous comments which identify the 
potential for inadvertent testing error if the standby mode and off 
mode testing is conducted under different ambient temperatures than 
active mode testing, but determined that the potential for such error 
is outweighed by the flexibility provided to manufacturers and testing 
laboratories to conduct standby mode and off mode testing separately 
from active mode testing. In addition, commenters did not provide 
information that would suggest that the more stringent ambient 
temperature requirements currently specified in the DOE dishwasher, 
dehumidifier, and conventional cooking product test procedures would 
reduce variability in the standby mode and off mode energy use 
measurement. For these reasons, today's final rule incorporates by 
reference in the new dishwasher and dehumidifier test procedures and 
amended conventional cooking products test procedure the ambient 
temperature requirements specified in section 4 of IEC Standard 62301 
(Second

[[Page 65956]]

Edition) for measuring standby mode and off mode power consumption.
    In response to the August 2012 SNOPR, AHAM, BSH, Samsung, and 
Whirlpool continued to suggest that the dishwasher active mode test 
should be conducted at the nominal center of the ambient temperature 
range, but acknowledged that a tighter tolerance would also help 
minimize test-to-test variation. Whirlpool supported the proposal to 
tighten the tolerance to 2 [deg]F, and stated that any 
additional burden associated with this requirement is small. Whirlpool 
commented that it will be able to meet the proposed tighter ambient 
temperature tolerance. None of the commenters provided information on 
whether all laboratories are capable of achieving a 2 
[deg]F temperature range, but AHAM, BSH, and Samsung believe that some 
laboratories would need to make significant investments to meet this 
requirement. BSH added that at certain times of the year its 
laboratories would not be able to meet the 75 2 [deg]F 
temperature range, requiring costly modifications to achieve consistent 
performance. BSH noted that it also conducts dishwasher testing 
according to the IEC dishwasher test procedure that requires an ambient 
temperature range of 64.4 to 71.6 [deg]F. The current DOE active mode 
temperature specification provides an overlap between the lower end of 
the DOE temperature range and the upper end of the IEC range, allowing 
BSH to conduct both tests in the same laboratory at the same time. 
DOE's proposal for 75 2 [deg]F would not allow this 
overlap, and could potentially require BSH to have separate 
laboratories for DOE and IEC testing. (AHAM, No. 35 at p. 7; BSH, No. 
36 at p. 3; Samsung, No. 33 at p. 1; Whirlpool, No. 32 at p. 1; 
Whirlpool, No. 34 at p. 2)
    DOE carefully considered these comments and whether the potential 
improvement in the test procedure results by requiring a tighter 
ambient temperature tolerance for dishwasher active mode testing would 
warrant the significant costs that could potentially be incurred by at 
least some test laboratories and manufacturers. Although it does not 
have information on the number of affected laboratories, DOE observes 
that at least one manufacturer would need to upgrade its facilities, 
and would incur additional cost by not being able to conduct all its 
active mode testing, i.e., testing both for demonstrating compliance 
with DOE energy conservation standards and for evaluating consumer 
utility associated with cleaning performance, in a single laboratory. 
Although test repeatability and reproducibility would be improved by 
specifying a more stringent ambient temperature tolerance, DOE 
determined that the significant potential costs do not warrant the 
benefits of such a specification. As a result, DOE is not changing the 
required range in ambient temperatures for active mode testing in the 
dishwasher test procedure. In addition, for the reasons stated in the 
August 2012 SNOPR, DOE is not amending the dishwasher test procedure to 
require that the active mode test be conducted at the nominal center of 
the ambient temperature range.
    AHAM and GE stated that the test room humidity should be specified 
for dehumidifier standby mode and off mode testing to prevent the unit 
from inadvertently cycling on. (AHAM, No. 14 at p. 7; GE, NOPR Public 
Meeting Transcript, No. 10 at p. 64) Neither commenter provided 
information on an appropriate ambient humidity level for this testing, 
and no such requirement is contained within IEC Standard 62301 (Second 
Edition). Therefore, DOE is not adopting an ambient humidity 
requirement in today's final rule for standby mode and off mode testing 
in the new dehumidifier test procedure. DOE does, however, clarify in 
section 4.2 of appendix X1 that standby mode and off mode testing 
should be conducted while ensuring that the dehumidifier does not enter 
active mode during the test.
2. Installation and Power Supply Requirements
    AHAM and Whirlpool supported the requirement to conduct standby 
mode and off mode testing at the factory or default setting, or where 
there are no indications of those settings, in the as-shipped 
condition, in accordance with section 5.2 of IEC Standard 62301 (Second 
Edition). According to these commenters, this requirement would provide 
clarity, ensure repeatability, and reduce testing burden. (AHAM, No. 14 
at pp. 3-4, 6; Whirlpool, No. 12 at pp. 2, 4; Whirlpool, NOPR Public 
Meeting Transcript, No. 10 at p. 58) AHAM also stated that it supports 
the power supply requirements proposed to be referenced from IEC 
Standard 62301 (Second Edition). (AHAM, No. 14 at pp. 7-8) DOE adopts 
in today's new dishwasher and dehumidifier test procedures and amended 
conventional cooking products test procedure references to the 
electrical supply voltage requirements in section 4, paragraph 4.3.2 
and portions of the installation and setup procedures in section 5, 
paragraph 5.2 of IEC Standard 62301 (Second Edition).
3. Standby Mode and Off Mode Testing Methodology
    In the December 2010 NOPR, DOE also proposed for all covered 
products to require measurement of standby mode and off mode power 
using section 5, paragraph 5.3 of IEC Standard 62301 (First Edition), 
clarified by requiring the product to stabilize for at least 30 minutes 
and using an energy use measurement period of not less than 10 minutes. 
Further, for any dishwasher or dehumidifier in which the power varies 
over a cycle, as described in section 5, paragraph 5.3.2 of IEC 
Standard 62301 (First Edition), the December 2010 NOPR proposed to 
require the use of the average power approach in section 5, paragraph 
5.3.2(a), with the same 30-minute minimum stabilization and 10-minute 
minimum measurement periods, as long as the measurement period 
comprises one or more complete cycles. 75 FR 75290, 75300-01 (Dec. 2, 
2010) DOE additionally proposed specific methodology for conventional 
cooking products in which power varies as a function of the time 
displayed. In that case, testers would be allowed to choose measuring 
standby power by means of either the 10-minute test or the 12-hour 
test, as described in section III.C of today's notice. According to the 
proposal, manufacturers could elect to conduct either a 10-minute test 
or a 12-hour test, or both, and results of the 10-minute test that are 
within 2 percent of the results for the 12-hour test would 
be deemed to be representative of average energy use. Id. at 75302-04, 
75328.
    In the September 2011 SNOPR, DOE updated its proposal to reference 
testing methodology from IEC Standard 62301 (Second Edition). DOE 
tentatively concluded that the application of the provisions of the 
Second Edition to all power measurements in standby mode and off mode 
for dishwashers and dehumidifiers would be appropriate, and proposed 
incorporation by reference of the relevant paragraphs of section 5.3 of 
IEC Standard 62301 (Second Edition) in the test procedures for these 
products. Further, DOE noted in the September 2011 SNOPR that although 
the Second Edition allows the choice of multiple test methods for both 
stable and unstable non-cyclic power consumption, the IEC preferred 
sampling method provides for a test duration that is approximately the 
same or shorter than the allowable IEC alternative methods and does not 
require classification of the nature of the power consumption (e.g., 
stable or unstable, non-cyclic) in advance of the test. By monitoring 
the variation in power consumption during the test, the

[[Page 65957]]

test operator could determine whether it is stable or unstable, and, 
thus, the required duration of the sampling periods. For cyclic power 
consumption, the Second Edition requires the use of the sampling 
method. Thus, DOE proposed in the September 2011 SNOPR to specify the 
use of the sampling method in section 5.3.2 of IEC Standard 62301 
(Second Edition) for all measures of standby mode and off mode power 
consumption for residential dishwashers and dehumidifiers. 76 FR 58346, 
58351-53 (Sep. 20, 2011).
    DOE did not receive comments in response to the proposed standby 
mode and off mode power consumption measurement methods for dishwashers 
and dehumidifiers, and for the reasons discussed, adopts such 
amendments in the new dishwasher and dehumidifier test procedures in 
today's final rule.
    For conventional cooking products, DOE tentatively concluded in the 
September 2011 SNOPR that section 5.3 of IEC Standard 62301 (Second 
Edition) includes provisions that are appropriate for measuring off 
mode and standby modes, except in the case of a unit's clock whose 
power consumption varies by the time displayed, and that the sampling 
method in section 5.3.2 of IEC Standard 62301 (Second Edition) would 
also provide for measurements with minimal test burden. Thus, DOE 
proposed in the September 2011 SNOPR for conventional cooking products 
to require the use of the sampling method in section 5.3.2 of IEC 
Standard 62301 (Second Edition), except as follows. In the narrow case 
of cooking products with power consumption that varies as a function of 
the time displayed, DOE determined that the application of the test 
methodology from IEC Standard 62301 (Second Edition) would cause 
manufacturers to incur significant burden that would not be warranted 
by any potential improved accuracy of the test measurement. For this 
reason, DOE continued to propose in the September 2011 SNOPR the 10-
minute and 12-hour test methods for these products in the conventional 
cooking products test procedure, based upon the average power method 
from IEC Standard 62301 (First Edition). The September 2011 SNOPR also 
proposed to amend the reference in 10 CFR 430.3 to add a reference to 
IEC Standard 62301 (Second Edition). DOE's proposal for conventional 
cooking products, based on relevant sections of IEC Standard 62301 
(Second Edition) would neither be affected by, nor impact, the testing 
procedures for microwave ovens other than section renumbering as 
appropriate. 76 FR 58346, 58351-53. (Sep. 20, 2011).
    AHAM and Whirlpool supported the 10-minute testing methodology for 
conventional cooking products with power consumption that varies as a 
function of the time displayed, but stated that the time that a product 
takes to return to the lowest power consumption state after setting the 
clock may vary and that this stabilization period may be shorter or 
longer than 10 minutes. They commented that DOE should require the 
clock to be set to a time of 3:33 minus the number of minutes of the 
stabilization period. According to AHAM, each manufacturer will know 
the length of the stabilization period for its products. AHAM also 
suggested that DOE could require manufacturers to submit in their 
certification report to DOE the length of the stabilization period, 
which should not be made public since it is confidential business 
information. (AHAM, No. 14 at p. 8; AHAM, No. 20 at pp. 2-3; AHAM, NOPR 
Public Meeting Transcript, No. 10 at pp. 73, 77; Whirlpool, No. 12 at 
p. 5; Whirlpool, No. 21 at p. 2) Whirlpool stated that the 12-hour test 
would place significant burden on manufacturers, and that the 10-minute 
test has been demonstrated to yield representative results. (Whirlpool, 
No. 21 at p. 2)
    ASAP commented that the proposed approach for allowing either a 10-
minute or 12-hour test was a reasonable balance between manufacturer 
test burden and enforcement. (ASAP, NOPR Public Meeting Transcript, No. 
10 at pp. 76-77) AHAM and Whirlpool questioned whether a model that met 
an energy conservation standard when tested by the manufacturer using 
the 10-minute method but that did not meet the standard when tested by 
DOE using the 12-hour method would be deemed compliant if the results 
between the two tests were within the 2-percent variation. Whirlpool 
believes that the option of two test methods is unnecessary. (AHAM, No. 
14 at p. 9; AHAM, No. 20 at p. 3; AHAM, NOPR Public Meeting Transcript, 
No. 10 at pp. 73-75; Whirlpool, No. 12 at p. 5; Whirlpool, No. 21 at p. 
2)
    Upon review of comments from interested parties, DOE concludes that 
a 12-hour test requirement would represent a significant burden to 
manufacturers, and that the alternative 10-minute method would minimize 
additional test burden. DOE agrees that the time required by certain 
products may be different than the 10-minute stabilization period 
provided in the 10-minute test method. DOE does not believe, however, 
that allowing the manufacturers to individually determine the 
stabilization period would optimize the accuracy and repeatability of 
the test procedure, particularly when the method is used at testing 
laboratories other than that of the manufacturer. Based on its testing, 
DOE determined that a requirement to set the display time to 3:23 and 
allowing a 10-minute stabilization period prior to a 10-minute 
measurement period would best balance the need for reproducibility of 
the test procedure with the burden placed on manufacturers. Therefore, 
DOE adopts in today's final rule the proposed standby mode and off mode 
testing methodology for conventional cooking products, but eliminating 
the 12-hour testing option for conventional cooking products with power 
consumption that varies as a function of the time displayed.
    DOE notes that the conventional cooking products test procedure is 
designed to provide an energy efficiency measurement consistent with 
representative average consumer use of these products, even if the test 
conditions and/or procedures may not themselves all be representative 
of average consumer use (e.g., testing with a display of only 3:33 to 
3:42). DOE's amendments reflect the statutory requirement, and the 
Department's longstanding view, that the overall objective of the test 
procedure is to measure the product's energy consumption during a 
representative average use cycle or period of use. (42 U.S.C. 
6293(b)(3)) Further, the test procedure requires specific conditions 
during testing that are designed to ensure repeatability while avoiding 
excessive testing burdens. Although certain test conditions specified 
in the test procedure may deviate from representative use, such 
deviations are carefully designed and circumscribed in order to attain 
an overall calculated measurement of the energy consumption during 
representative use. Thus, it is--and has always been--DOE's view that 
products should not be designed such that the energy consumption drops 
during test condition settings in ways that would bias the overall 
measurement, thereby making it unrepresentative of average consumer 
use. If a manufacturer incorporates a power-saving mode as part of the 
appliance's routine operation, DOE's test procedure would produce a 
representative measure of average consumer use if the unit powered down 
during the 10-minute test period for the same percentage of time that 
such powering down would be expected to occur during a typical 12-hour 
period, and thus, such operation would be permissible. It has been the

[[Page 65958]]

Department's long-held interpretation that the purpose of the test 
procedure is to measure representative use. Ultimately, if DOE 
identifies a broad pattern of behavior which has the effect of 
circumventing its test procedure provisions, the Department may 
consider reopening the conventional cooking products test procedure for 
further rulemaking.

F. Calculation of Energy Use Associated With Operational Modes

1. Standby Mode and Off Mode
    In the December 2010 NOPR, DOE proposed a methodology for measuring 
energy consumption in modes other than active washing mode for 
dishwashers and active cooking mode for conventional cooking products; 
i.e., inactive (standby) mode and off mode, as well as delay start mode 
and cycle finished mode. These modes are collectively referred to as 
low-power modes. DOE also raised the possibility of using a similar 
methodology for measuring low-power modes for dehumidifiers, including 
inactive (standby) mode, off mode, off-cycle mode, and bucket full/
removed mode. DOE proposed in the December 2010 NOPR to allocate 
specific annual hours to each of the active, standby, and off modes. 
Using this approach, the annual energy use associated with the low-
power modes would be calculated by: (1) Calculating the product of 
wattage and allocated hours for all possible low-power modes; (2) 
summing the results; and (3) dividing the sum by 1,000 to convert from 
Wh to kWh. For each product, DOE estimated the hours allocated to each 
mode, and for those products with both electronic controls and a 
mechanical on/off switch, DOE proposed to evenly split the hours 
between inactive mode and off mode. For the per-cycle energy use 
metrics for dishwashers and conventional cooking products, this value 
would be divided by the proposed annual active use cycles per year. For 
dehumidifiers, which measure energy use over a 24-hour period, the 
annual energy use in the low-power mode would be divided by the active 
mode hours per year and multiplied by 24 hours. 75 FR 75290, 75306, 
75310-15 (Dec. 2, 2010).
    As an alternate approach for dishwashers and conventional cooking 
products, DOE also proposed measuring power consumption for only off 
and inactive modes for the purpose of calculating the total energy 
consumed in all low-power modes. Using this approach, energy use in 
delay start and cycle finished mode would be accounted for by 
allocating all the hours not associated with active washing or cooking 
mode to the inactive (standby) and off modes and then measuring standby 
or off mode power. For dehumidifiers, DOE considered the possibility of 
a similar alternative approach in which energy use in which all hours 
other than active dehumidification mode would be allocated to inactive 
mode, off-cycle mode, and off mode. DOE observed that dehumidifiers are 
generally capable of either off mode or inactive mode, depending on the 
type of controls, when the unit is plugged in but not turned on. Each 
type of dehumidifier would operate in off-cycle mode when the unit is 
powered on and the relative humidity level in the room is below the 
dehumidifier humidity set point. 75 FR 75290, 75306, 76308, 75310-13 
(Dec. 2, 2010). DOE retained these proposals in the September 2011 
SNOPR and received comments in support of the alternate approach. As a 
result, DOE proposed the alternate approach for dishwashers and 
conventional cooking products in the May 2012 SNOPR. 77 FR 31444, 31451 
(May 25, 2012).
    AHAM, BSH, the California Utilities, PG&E, and Whirlpool opposed 
the allocation of annual hours to different modes proposed for the 
dishwasher, dehumidifier, and conventional cooking products test 
procedures, commenting that DOE did not base the proposals on 
sufficient U.S. consumer use data. AHAM, BSH, and Whirlpool further 
commented that if DOE moves forward with its proposal, the alternative 
approach is preferable. (AHAM, No. 14 at pp. 9-14; AHAM, No. 27 at p. 
13; AHAM, NOPR Public Meeting Transcript, No. 10 at pp. 85, 97-98, 109; 
BSH, No. 28 at p. 11; California Utilities, No. 16 at p. 3; PG&E, No. 
17 at p. 3; Whirlpool, No. 12 at p. 6; Whirlpool, No. 26 at pp. 1, 3) 
The California Utilities and PG&E commented that delay start mode 
should be measured as part of active mode, but supported including 
delay start energy use in standby mode energy use as a temporary 
measure. ASAP, the California Utilities, and PG&E questioned DOE's 
estimates of the annual hours spent in cycle finished mode, while GE 
stated that DOE's estimates for dehumidifier bucket full/removed mode 
are too high. (ASAP, NOPR Public Meeting Transcript, No. 10 at pp. 109-
110; California Utilities, No. 16 at pp. 2, 4; PG&E, No. 17 at pp. 2,4; 
Whirlpool, NOPR Public Meeting Transcript, No. 10 at pp. 94-95)
    ASAP, the California Utilities, the NOPR/SNOPR2 Joint Comment, and 
PG&E stated that DOE should specify the placement of the mechanical on/
off switch so that consumers would turn the product off, thereby 
justifying the proposed split between inactive mode and off mode hours. 
AHAM (ASAP, NOPR Public Meeting Transcript, No. 10 at pp. 87, 109; 
California Utilities, No. 16 at p. 4; NOPR/SNOPR2 Joint Comment, No. 13 
at p. 6; PG&E, No. 17 at p. 4) AHAM commented that DOE should require 
that mechanical on/off switch be accessible to the consumer, but should 
not specify product design. (AHAM, No. 14 at p. 12)
    In today's final rule, DOE maintains its determination from the May 
2012 SNOPR for both dishwashers and conventional cooking products, and, 
as contemplated in the December 2010 NOPR, makes a similar 
determination for dehumidifiers, that the power consumption in each of 
the low-power modes is similar, and that in such a case, measuring 
power consumption of each mode separately would introduce significant 
test burden without a corresponding improvement in a representative 
measure of annual energy use. In consideration of support from 
interested parties for the alternate calculation method and the lack of 
additional consumer use data that would improve the original proposal, 
DOE establishes in the new dishwasher and amended conventional cooking 
products test procedures provisions to account for standby mode and off 
mode energy use by measuring inactive mode and off mode power 
consumption only, and allocating that power consumption to all hours 
spent in the low-power modes combined.
    The same alternative calculation of combined low-power mode energy 
use is adopted in today's final rule in the new dehumidifier test 
procedure. The provisions require that dehumidifiers with off mode 
capability (i.e., those units with electronic controls that may be shut 
off with a mechanical switch or with mechanical controls) shall be 
measured in off mode and off-cycle mode. For dehumidifiers not capable 
of operation in off mode (i.e., units with electronic controls that may 
not be shut off with a mechanical switch), inactive mode and off-cycle 
mode shall be measured. The annual hours for all low-power modes 
combined shall be split evenly between off-cycle mode and either 
inactive mode and off mode, depending on the unit's capability. 
Although DOE did not previously propose this specific alternative 
methodology for dehumidifiers, it suggested that such an approach could 
be adopted in the final rule. DOE is adopting this approach today after 
noting the preponderance of supporting comments for the alternative 
approach, and weighing carefully the benefits of

[[Page 65959]]

reduced testing burden of this approach against the minor improvements 
in accuracy of the standby mode and off mode energy use obtained by 
measuring each low-power mode separately.
2. Fan-Only Mode
    In the May 2012 SNOPR, DOE proposed to define fan-only mode in the 
test procedures for dishwashers and conventional cooking products as an 
active mode in which a fan circulates air for a finite period of time 
after the end of the dishwasher cycle or conventional cooking product 
heating function, as indicated to the consumer. DOE also proposed 
provisions to measure energy use in fan-only mode, in which the power 
consumption and duration of fan-only mode would be measured at the end 
of each active mode cycle required by the test procedure, and the 
resulting energy consumption would be included in the energy efficiency 
metrics for that product. 77 FR 31444, 31451 (May 25, 2012).
    In response to the May 2012 SNOPR, the NOPR/SNOPR2 Joint Comment 
stated that it supports incorporating measurement of fan-only mode 
energy use in the dishwasher and conventional cooking products test 
procedures, as this would provide an incentive to manufacturers to 
reduce fan-only mode energy consumption. (NOPR/SNOPR2 Joint Comment, 
No. 29 at p. 1) AHAM, BSH, and Whirlpool stated they would not oppose 
the measurement of fan-only mode energy use for dishwashers or 
conventional cooking products, as long as fan-only mode is not a user-
selectable option. Whirlpool commented that classifying fan-only mode 
as part of active mode would be consistent with a determination that 
active mode persists until the end of the operating cycle. However, 
AHAM, BSH, and Whirlpool stated that measuring energy consumption in 
this mode according to the proposed method would represent a 
significant burden due to the increased length of each test. AHAM, BSH, 
and Whirlpool recommended that DOE allow as an option a one-time 
measurement or sampling approach to measure fan-only mode energy use 
over a brief time period combined with a calculation to properly 
account for its contribution to annual energy use in the test 
procedures for dishwashers and conventional cooking products. (AHAM, 
No. 27 at pp. 2-3; BSH, No. 28 at p. 2; Whirlpool, No. 26 at pp. 1-2)
    Whirlpool further commented that DOE's estimate that a dishwasher 
fan could run for 4 hours after each cycle, consuming 17 kWh per year 
or 4.7 percent of the current maximum energy consumption, was 
incorrect. Whirlpool stated that fan operation is a function of the 
residual heat remaining in the unit after completion of the wash cycle 
and the degree of drying selected, and thus, the fan will not operate 
for this length of time on every cycle. Whirlpool similarly commented 
that DOE's estimate that a conventional cooking product fan could run 
for 3.5 hours after each cycle, consuming as much as 38 kWh per year, 
was incorrect because fan operation is a function of the residual heat 
remaining in the unit after completion of the cooking cycle and of the 
ambient temperature. (Whirlpool, No. 26 at p. 2)
    As part of the calculation in the May 2012 SNOPR, DOE provided a 
range of the annual impacts of fan-only energy consumption in 
residential dishwashers and conventional cooking products. While DOE 
agrees that most dishwashers and conventional cooking products will not 
operate in fan-only mode for 4 hours or 3.5 hours, respectively, DOE is 
aware of products capable of these durations, and therefore concludes 
that the values in the May 2012 SNOPR are appropriate estimates of the 
maximum amount of energy consumed in this mode. However, the proposal 
for dishwasher and conventional cooking product test methods for 
measuring energy use in fan-only mode in the May 2012 SNOPR would be 
based on the actual length of fan-only mode for the product under test.
    For the August 2012 SNOPR, DOE continued to propose the methodology 
first proposed in the May 2012 SNOPR, and also provided an alternative 
methodology to reduce test burden in which, if fan-only mode is not a 
user-selectable option, the power consumption would be measured for a 
brief time period, such as 10 minutes, and then extrapolated over the 
length of the entire fan-only mode cycle. DOE sought representative 
data on the length of the fan-only mode cycle for dishwashers and 
conventional cooking products. 77 FR 49064, 49067 (Aug. 15, 2012).
    AHAM, BSH, Samsung, and Whirlpool support the alternative approach 
under which the energy use of fan-only mode would be measured only if 
is not a user-selectable option, although they noted this approach 
could produce non-representative results if the energy use during fan-
only mode is not constant. These commenters cited an example in which 
the fan could stop and start over the course of the fan-only mode, or 
it could operate at a different wattage at times other than during the 
sampling period. Therefore, AHAM, BSH, Samsung, and Whirlpool suggest 
that DOE include language to require that the measured time period of 
10 minutes be representative of average energy usage. If the 
measurement period is not representative, the full fan-only mode should 
be measured. (AHAM, No. 35 at pp. 9-10; BSH, No. 36 at p. 3; Samsung, 
No. 33 at p. 1; Whirlpool, No. 32 at p. 1) ASAP, NCLC, and NRDC, 
jointly (hereafter the ``SNOPR3 Joint Comment'') support measuring fan-
only mode energy use for the duration of fan-only mode, as originally 
proposed in the May 2012 SNOPR. These commenters stated they are not 
aware of available data on the representative cycle times of fan-only 
mode for dishwashers or conventional cooking products, and that given 
the wide variations in fan-only cycle times observed in the products, 
any assumed cycle time would result in significantly over-estimating or 
under-estimating the actual energy consumption in fan-only mode for a 
majority of products. (SNOPR3 Joint Comment, No. 37 at pp. 1-2)
    Measuring fan-only mode energy use over the full duration of fan-
only mode may provide slightly more accuracy in the results, but such 
an approach can represent significant testing burden in the event that 
the duration of fan-only mode extends to several hours. Additionally, 
DOE agrees with the SNOPR3 Joint Comment that any single value for a 
representative duration of fan-only mode for a dishwasher or 
conventional cooking product that DOE may prescribe in its test 
procedures would likely not result in representative energy use for a 
number of such products. To use the alternate method and extrapolate 
the results over the duration of fan-only mode, manufacturers must know 
and use the length of the fan-only mode operation. Use of the 
alternative approach would substantially reduce testing burden while 
resulting in representative energy use for this mode. Therefore, in 
today's final rule, DOE adopts provisions in the new dishwasher test 
procedure and amends the current conventional cooking products test 
procedure to include the methodology proposed in the May 2012 SNOPR for 
measuring energy use over the full duration of fan-only mode, but also 
allow the choice of the alternative method, using a testing duration of 
10 minutes, where the duration of fan-only mode is known and the 
resulting energy use extrapolated over the entire fan-only mode will be 
representative. For conventional cooking products, DOE's proposed 
amendments for measuring fan-only mode energy use are corrected in 
today's final rule so that the energy use

[[Page 65960]]

is determined in kilowatt-hours rather than hours.
    AHAM and Whirlpool also commented that DOE should clarify what ``as 
indicated to the consumer'' means in the fan-only mode definition. 
According to AHAM, this could refer to the end of the heating function 
for a cooking product or dishwasher cycle, or when the consumer is 
notified of the end of the heating function or dishwasher cycle and the 
fan is running, or something else. (AHAM, No. 27 at p. 2; Whirlpool, 
No. 26 at p. 1) In today's final rule, DOE provides further 
clarification in the definition of fan-only mode that indication to the 
consumer of the end of the cycle is by means of a display, indicator 
light, or audible signal.
3. Dishwasher Water Softener Regeneration
    In the May 2012 SNOPR, DOE proposed a method for measuring the 
energy consumed during regeneration cycles for water softeners built 
into certain residential dishwashers. The proposed test procedure would 
measure the machine electrical energy consumption and the water 
consumption of a water softener regeneration cycle. DOE considered 
information submitted by manufacturers in petitions for waiver from the 
DOE test procedure to determine an appropriate method for incorporating 
water softener regeneration energy and water consumption into the 
overall metrics. 77 FR 31444, 31449-52 (May 25, 2012).
    The NOPR/SNOPR2 Joint Comment supported the proposed water softener 
regeneration test procedure, and noted that the test procedure would 
eliminate the need for additional test procedure waivers. (NOPR/SNOPR2 
Joint Comment, No. 29 at p. 1) AHAM, BSH, and Whirlpool opposed the 
proposed test method because it would be burdensome and result in only 
a small amount of additional measured energy and water consumption. 
Whirlpool commented that it submitted detailed data on the frequency, 
energy use, and water use of water softeners in its petition for 
wavier, and in granting the waiver, DOE agreed to add constant values 
of 4 kWh and 23 gallons per year to the results calculated under the 
test procedure. According to Whirlpool, these represent a very modest 
amount of annual energy and water consumption. (AHAM, No. 27 at pp. 3-
4; BSH, No. 28 at p. 2; BSH, No. 36 at p. 2; Whirlpool, No. 26 at pp. 
1-3; Whirlpool, No. 34 at p. 2)
    AHAM, BSH, and Whirlpool noted that the proposed test method is not 
consistent with the approach taken by the European standards EN 50242/
EN 60436 and the IEC Standard 60436, which disregard energy and water 
consumption during water softener regeneration, and that the lack of 
harmonization increases test burden. These commenters also stated that 
if the water softener does not operate as part of the ``normal'' energy 
cycle and is user selectable, it should be treated like other options 
in the test procedure and should not be measured. (AHAM, No. 27 at p. 
4; BSH, No. 28 at pp. 2-3; BSH, No. 36 at p. 2; Whirlpool, No. 26 at 
pp. 1-3; Whirlpool, No. 34 at p. 2)
    AHAM, BSH, and Whirlpool further stated that DOE overestimated the 
energy use associated with water softener regeneration cycles because 
it did not account for households with hard water that use home water 
softening systems. According to BSH, dishwashers with built-in water 
softening systems are the most costly units, and homes that can afford 
these high-end dishwashers and have water hardness above 180 parts per 
million (ppm) (the maximum water hardness for which modern phosphate-
free detergents are effective) are more likely to have home water 
softening systems, although BSH did not provide supporting data. BSH 
stated that it produces about 50,000 units per year with built-in water 
softening systems, totaling a small amount of energy consumption for 
water softener regeneration according to the current waiver calculation 
methods. (AHAM, No. 27 at p. 4; BSH, No. 28 at p. 2; BSH, No. 36 at p. 
2; Whirlpool, No. 26 at p. 1) The NOPR/SNOPR2 Joint Comment stated that 
in the absence of data regarding the percentage of households with hard 
water that have their entire water supply softened, DOE's assumption 
that all dishwashers with built-in water softeners perform the periodic 
regeneration is reasonable. (NOPR/SNOPR2 Joint Comment, No. 29 at pp. 
1-2)
    Whirlpool also commented that specifying an exact test water 
hardness of 217 mg/L (12.7 grains) would not be practical, and a 
tolerance would be required, such as 9 to 14 grains, allowing 
laboratories to use existing water supplies and reduce the additional 
test burden of special mixing of water for this test. (Whirlpool, No. 
26 at p. 3)
    AHAM, BSH, and Whirlpool commented that if DOE includes water 
softener regeneration in the test procedure, DOE should adopt a method 
of adding constant values for the water and energy use, similar to the 
method DOE agreed to in the test procedure waivers, which would be 
provided by the manufacturer and would account for regeneration 
frequency, water use, and energy use. (AHAM, No. 27 at p. 4; BSH, No. 
28 at p. 3; BSH, No. 36 at p. 2; Whirlpool, No. 26 at pp. 1, 3; 
Whirlpool, No. 34 at p. 2)
    In the waivers granted to manufacturers for water softening 
dishwashers, DOE has already determined that the energy and water use 
for water softener regeneration, although small in comparison to the 
overall energy and water use of the dishwasher, must be included to 
accurately represent true energy and water consumption characteristics. 
DOE recognizes that the proposed methodology to measure water softener 
regeneration would result in a significant increase in testing burden, 
by requiring up to 10 additional testing cycles to determine the energy 
and water use associated with that process. The waivers granted to 
manufacturers of different water softening dishwashers demonstrate that 
the values for the additional water and energy consumption necessary 
for water softener regeneration, as well as the frequency of the 
regeneration process, will vary depending on the specific model of 
dishwasher. For that reason, DOE cannot adopt fixed values for these 
parameters in the dishwasher test procedure. As an alternative approach 
that will minimize significantly the testing burden for including water 
softener regeneration in the dishwasher test procedure, DOE adopts in 
appendix C1 measures of energy and water consumption for water softener 
regeneration using manufacturer-reported values for the energy and 
water use for each regeneration cycle and the number of annual 
regeneration cycles. In today's final rule, DOE also amends 10 CFR 
429.19 to require manufacturers to certify and submit to DOE the fixed 
values, along with data and calculations by which they are derived, for 
each basic dishwasher model equipped with a built-in water softener 
system.
    DOE does not have data available at this time to determine the 
percentage of households with hard water that have their entire water 
supply softened, and for that reason does not provide an adjustment 
factor to the energy and water use calculations adopted in today's 
final rule. Because DOE is not adopting methodology for conducting 
water softener regeneration testing, but instead is incorporating 
energy and water use measures by means of fixed values, DOE is not 
adding any specification in the new dishwasher test procedure for the 
supply water hardness.

[[Page 65961]]

G. Measures of Energy Consumption

    For the December 2010 NOPR, DOE analyzed whether it is technically 
feasible, as required by EPCA, to combine the existing measures of 
energy consumption for dishwashers, dehumidifiers, and conventional 
cooking products with standby mode and off mode energy use to form a 
single metric. DOE's tentative conclusions at that time are discussed 
as follows.
1. Dishwashers
    Because the dishwasher test procedure already combines measures of 
active mode energy consumption and a simplified measure of standby mode 
energy use to derive EAEU, the current energy use metric for standards, 
it is technically feasible to incorporate standby mode and off mode 
energy consumption into the overall energy efficiency descriptor. 
Furthermore, DOE noted in the December 2010 NOPR that its analysis of 
overall energy use for dishwashers shows that the standby mode and off 
mode energy use is of a magnitude that it would materially affect that 
standard-setting process without overwhelming the effects of differing 
levels of active mode energy use . Therefore, a combined measure of 
energy efficiency for dishwashers is a meaningful measure. DOE proposed 
to amend the calculation of EAEU to incorporate the revised measures of 
standby mode and off mode energy consumption, and the revised EAEU 
metric would satisfy the EPCA requirement to integrate standby mode and 
off mode energy consumption into the overall energy consumption metric. 
75 FR 75290, 75314 (Dec. 2, 2010).
    EPCA requires that DOE must determine to what extent, if any, a 
proposed test procedure would alter the measured energy efficiency of 
any covered product as determined under the existing test procedure. 
(42 U.S.C. 6293(e)(1)) The current DOE dishwasher test procedure 
defines ``standby mode'' as the lowest power consumption mode which 
cannot be switched off or influenced by the user. DOE proposed in the 
December 2010 NOPR to measure an additional standby mode (i.e., cycle 
finished mode). However, the proposed amendments clarified that the 
provisions related to the new measures of energy consumption in standby 
mode and off mode would not be required to be used by manufacturers 
until the compliance date of any amended dishwasher standards 
addressing standby mode and off mode energy use. Therefore, the 
proposed amendments to the dishwasher test procedure regarding standby 
mode and off mode would not alter the measured efficiency of any 
covered product under the existing test procedure. 75 FR 75290, 75314 
(Dec. 2, 2010).
    Because the current dishwasher test procedure already incorporates 
standby energy use in the EAOC, it is technically feasible to 
incorporate both standby mode and off mode energy use into the EAOC. 
Therefore, DOE proposed in the December 2010 NOPR to amend the EAOC 
calculation to incorporate the revised measures of standby mode and off 
mode energy consumption. Id.
    The dishwasher test procedure currently provides instructions for 
rounding EAOC to the nearest dollar per year. 10 CFR 430.23(c)(1). 
However, no instructions are provided for rounding the final values of 
EAEU or water consumption per cycle (the metrics for the current 
dishwasher energy conservation standards), nor the contributory 
measurements and interim calculations. This lack of specificity for 
rounding may lead to uncertainty in the reported metrics or to 
discrepancies among test laboratories for the same product, resulting 
in difficulty for regulated entities to ascertain, certify, and report 
compliance with the existing standards. Therefore, DOE proposed in the 
December 2010 NOPR to add instructions to 10 CFR 430.23(c) requiring 
that water consumption be rounded to one decimal place, and EAEU be 
rounded to the nearest whole kWh/year. DOE also proposed at that time 
to provide rounding instructions for EF, but as discussed in section 
III.J, is removing provisions for determining EF because it is 
obsolete. 75 FR 75290, 75314 (Dec. 2, 2010).
    AHAM commented that is did not oppose modifying the existing EAEU 
metric for dishwashers as proposed, and supported the rounding 
instructions proposed. (AHAM, No. 14 at p. 12) Whirlpool stated that, 
although it is technically feasible to create an integrated metric for 
dishwashers, delay start mode and cycle finished mode represent de-
minimus contributors to EAEU and EAOC. According to Whirlpool, the 
annual cost of energy consumed in inactive/off mode would range from $0 
to $0.65. Whirlpool stated that measurement of these modes adds cost 
and complication to the test procedure with no corresponding value, and 
should not be included in the test procedure. (Whirlpool, No. 12 at p. 
6) Because integrated dishwasher energy use metrics are technically 
feasible, DOE revises in today's final rule the EAEU and EAOC metrics 
in the new dishwasher test procedure to incorporate measures of standby 
mode and off mode energy use, as required by 42 U.S.C. 6295(gg). DOE 
also adopts in 10 CFR 430.23(c) the rounding instructions for EAEU and 
water consumption that were proposed in the December 2010 NOPR.
2. Dehumidifiers
    The DOE test procedure for dehumidifiers currently only 
incorporates energy consumption in the form of EF (see 10 CFR part 430, 
subpart B, appendix X for details). EF, defined as liters of water 
removed from the air per kWh, is the metric for the current energy 
conservation standards for dehumidifiers. (10 CFR 430.32(v)) The 
current DOE test procedure for dehumidifiers does not account for 
standby mode and off mode energy use.
    In the December 2010 NOPR, DOE noted that its analysis of overall 
energy use for dehumidifiers indicates the standby mode and off mode 
energy use is of a magnitude that it would materially affect that 
standard-setting process without overwhelming the effects of differing 
levels of active mode energy use. Therefore, DOE stated that a combined 
measure of energy efficiency for dehumidifiers is a meaningful measure. 
75 FR 75290, 75314-15 (Dec. 2, 2010).
    DOE proposed in the December 2010 NOPR to establish an integrated 
energy factor (IEF) measure to account for the product's energy use in 
standby mode and off mode, as well as the energy use of the product's 
main functions. DOE noted that the calculation of EF represents the 
liters of water removed from the air per kWh of energy consumed over a 
given period of time, such as the number of active mode hours per year. 
If the ratio of the annual standby mode and off mode hours to the 
annual active mode hours is used to apportion standby mode and off mode 
power consumption over the active mode test period of one day, it is 
possible to calculate an IEF that incorporates both the efficiency of 
water removal from the air and the standby mode and off mode energy 
consumption. DOE proposed to calculate IEF using the following 
calculation: (The liters of water removed over the active mode test 
cycle)/((the active mode energy consumption over the active mode test 
cycle) + ((the standby mode and off mode annual energy consumption \14\ 
x 24 hours)/(the active mode hours per year))). 75 FR 75290, 75315 
(Dec. 2, 2010).
---------------------------------------------------------------------------

    \14\ The standby mode and off mode annual energy consumption is 
equivalent to the average standby mode and off mode power multiplied 
by the number of standby mode and off mode hours per year.

---------------------------------------------------------------------------

[[Page 65962]]

    Section 3 of the current dehumidifier test procedure provides 
instructions for rounding EF to two decimal places. DOE proposed in the 
December 2010 NOPR to round the IEF value to two decimal places as 
well. Id.
    AHAM stated that is did not oppose the proposed integrated metric 
for dehumidifiers, and supports the rounding instructions proposed. 
(AHAM, No. 14 at p. 12) Whirlpool stated that, although it is 
technically feasible to create an integrated metric for dehumidifiers, 
delay start mode and bucket full/removed mode represent de-minimus 
contributors to annual energy consumption and operating cost. According 
to Whirlpool, the annual cost of energy consumed in off-cycle and 
inactive modes would range from $0 to $0.36. Whirlpool stated that 
measurement of these modes adds cost and complication to the test 
procedure with no corresponding value, and should not be included in 
the test procedure. (Whirlpool, No. 12 at p. 6) Because an integrated 
dehumidifier energy use metric is technically feasible, DOE adopts in 
today's final rule the new IEF metric in the new dehumidifier test 
procedure to incorporate measures of standby mode and off mode energy 
use, as required by 42 U.S.C. 6295(gg). DOE also adopts the rounding 
instructions for IEF that were proposed in the December 2010 NOPR.
3. Conventional Cooking Products
    The DOE test procedures for conventional cooking tops, ovens, and 
ranges currently incorporate various measures of energy consumption. 
These include test energy consumption, annual cooking energy 
consumption, annual energy consumption of any continuously-burning 
pilot lights, annual self-cleaning energy consumption, annual clock 
energy consumption, total annual energy consumption, and cooking 
efficiency. (See 10 CFR part 430, subpart B, appendix I.) The test 
procedure also provides a calculation for EF \15\ and EAOC. Although 
there are no current energy conservation standards based on performance 
for conventional cooking products (see 10 CFR 430.32(j)), historically, 
DOE's rulemaking analyses when considering standards have used EF as 
the energy conservation metric for conventional cooking products.
---------------------------------------------------------------------------

    \15\ ``Energy factor'' is defined as the ratio of the annual 
useful energy output to the total annual energy input.
---------------------------------------------------------------------------

    In the December 2010 NOPR, DOE noted that the conventional cooking 
products test procedure currently combines measures of energy 
consumption and narrow forms of standby energy use, including 
continuously-operating clock and gas standing pilot light energy 
consumption, to derive an overall ``energy efficiency measure.'' 
Therefore, a combined measure of energy efficiency for conventional 
cooking products has already been demonstrated to be a workable and 
meaningful measure. For this reason, DOE tentatively concluded that it 
would be technically feasible to incorporate standby mode and off mode 
energy consumption into the overall energy efficiency descriptor (i.e., 
EF). In the December 2010 NOPR, DOE proposed to establish, for 
conventional electric ovens, the ``integrated annual energy 
consumption,'' defined as the sum of the annual standby mode and off 
mode energy consumption, annual primary cooking energy consumption, and 
annual primary self-cleaning energy consumption, expressed in kWh. For 
conventional gas ovens that use electrical energy, the ``integrated 
annual electrical energy consumption'' would be defined as the sum of 
the annual standby mode and off mode energy consumption, annual 
secondary cooking energy consumption,\16\ and annual secondary self-
cleaning energy consumption, expressed in kWh. For conventional 
electric ovens, IEF would be defined as the (annual useful cooking 
energy output)/(integrated annual energy consumption). For conventional 
gas ovens, IEF would be defined as the (annual useful cooking energy 
output)/(annual gas energy consumption + integrated annual electrical 
energy consumption). DOE also proposed similar integrated annual energy 
consumption and IEF metrics for multiple conventional ovens (i.e., 
cooking appliances that include more than one conventional oven). 75 FR 
75290, 75315 (Dec. 2, 2010).
---------------------------------------------------------------------------

    \16\ ``Secondary cooking energy consumption'' includes any 
electrical energy consumption of a conventional gas cooking product 
during active mode operation.
---------------------------------------------------------------------------

    Also in the December 2010 NOPR, DOE proposed to establish measures 
integrating the product's energy use in standby mode and off mode with 
energy use during the main functions of the products. For conventional 
electric cooktops, the ``integrated annual energy consumption'' would 
be defined as the (annual standby mode and off mode energy consumption) 
+ (annual useful cooking energy output/conventional cooktop cooking 
efficiency), expressed in kWh. For conventional gas cooktops, the 
``integrated annual electrical energy consumption'' would be defined as 
the sum of the annual standby mode and off mode energy consumption, 
annual energy consumption for cooking, and annual energy consumption of 
the gas standing pilot light, expressed in kWh. For conventional 
electric cooktops, IEF would be defined as the annual useful cooking 
energy output divided by the electric cooktop integrated annual energy 
consumption. For conventional gas cooktops, IEF would be defined as the 
annual useful cooking energy output divided by the gas cooktop 
integrated annual energy consumption. Id.
    DOE proposed in the December 2010 NOPR to establish the following 
measures of energy consumption for conventional kitchen ranges (i.e., a 
cooktop and oven combined). ``Integrated annual energy consumption'' 
would be the sum of the annual cooking energy consumption of each of 
its components plus the conventional range annual standby mode and off 
mode energy consumption.\17\ The IEF of a kitchen range would be the 
sum of the annual useful cooking energy output of each component 
divided by the sum of the integrated annual energy consumption of each 
component. 75 FR 75290, 75315-16 (Dec. 2, 2010).
---------------------------------------------------------------------------

    \17\ DOE proposes to measure the standby mode and off mode 
energy consumption for a conventional range as a single product and 
to add the standby mode and off mode energy consumption separately 
in the calculation of the integrated annual energy consumption. It 
proposes this so that the standby mode and off mode power 
consumption is not measured separately for each component (i.e., 
cooktop and oven) and then summed with the cooking annual energy 
consumption, which would effectively double count the contribution 
of standby mode and off mode energy consumption.
---------------------------------------------------------------------------

    DOE is also proposed in the December 2010 NOPR to amend the 
estimated annual energy cost calculations in 10 CFR 430.23(i) to 
include the cost of energy consumed in standby mode and off mode for 
conventional cooking products. 75 FR 75290, 75316 (Dec. 2, 2010). The 
cooking products test procedure currently provides instructions for 
rounding EAOC to the nearest dollar per year, and the cooking 
efficiency and energy factor to three significant digits. 10 CFR 
430.23(i)(1), (2), (4). DOE proposed in the December 2010 NOPR to amend 
the test procedure to provide similar instructions requiring that EAOC 
based on total integrated annual electrical energy consumption be 
rounded to the nearest dollar per year and IEF to three significant 
digits. 75 FR 75290, 75316 (Dec. 2, 2010).
    AHAM commented that is did not oppose the proposed integrated 
metrics for conventional cooking products, and supports the rounding 
instructions

[[Page 65963]]

proposed. (AHAM, No. 14 at p. 12) Whirlpool stated that, although it is 
technically feasible to create an integrated metric for conventional 
cooking products, delay start mode, cycle finished mode, and Sabbath 
mode represent de-minimus contributors to annual energy consumption and 
operating cost. Whirlpool stated that measurement of these modes adds 
cost and complication to the test procedure with no corresponding 
value, and should not be included in the test procedure. (Whirlpool, 
No. 12 at p. 6) ASAP stated that an integrated metric for conventional 
cooking products could preclude the possibility of a future standard 
for standby energy use for conventional cooking products, as is being 
considered for microwave ovens. (ASAP, NOPR Public Meeting Transcript, 
No. 10 at p. 120.
    Because integrated energy use metrics for conventional cooking 
products are technically feasible, DOE adopts in today's final rule new 
IEF and integrated annual energy consumption metrics in the cooking 
products test procedure as described to incorporate measures of standby 
mode and off mode energy use, as required by 42 U.S.C. 6295(gg). The 
cooking products test procedure amendments also include separate 
measures of standby mode and off mode energy use that feed into the 
calculation of IEF. Should DOE in the future consider new energy 
efficiency standards for conventional cooking products, DOE will take 
appropriate action consistent with 42 U.S.C. 6295(gg). DOE also amends 
in 10 CFR 430.23(i) the estimated annual energy cost calculations to 
include the cost of energy consumed in standby mode and off mode for 
conventional cooking products, as well as to provide rounding 
instructions for EAOC and IEF as proposed in the December 2010 NOPR.

H. Dishwasher Test Procedure Clarifications

1. Energy Test Cycle Selection and Normal Cycle Definition
    DOE proposed in the May 2012 SNOPR that soil-sensing dishwashers be 
tested on the normal cycle under section 2.6.3 of appendix C if soil-
sensing is available as an option in the normal cycle. If soil-sensing 
is not available for the normal cycle, DOE proposed that the dishwasher 
be tested by selecting the cycle type that uses the soil-sensing 
system, and contains all the elements of a normal cycle including the 
power-dry feature (if such a feature is provided). 77 FR 31444, 31452-
53 (May 25, 2010). DOE continued to propose this clarification in the 
August 2012 SNOPR and further proposed that, for units with multiple 
temperature options, the unit shall be tested at the manufacturer-
recommended setting, or absent a manufacturer recommendation, at the 
highest temperature setting. 77 FR 49064, 49065-66 (Aug. 15, 2012).
    AHAM, BSH, and Whirlpool opposed the proposals in the May 2012 
SNOPR and the August 2012 SNOPR, stating that it contradicts the 
definition of normal cycle, may not represent typical consumer usage, 
and creates confusion for the tester and consumer. These commenters 
stated that the ``normal cycle'' is the appropriate energy test cycle, 
and manufacturers must assume the consumer will use the manufacturer-
recommended cycle even if that cycle is non-soil-sensing on a 
dishwasher capable of soil-sensing. The commenters further stated that 
manufacturers may do this in order to provide soil-sensing only on a 
specialty cycle(s), such as the cycle intended for washing pots and 
pans, and then recommend the non-soil-sensing normal cycle to 
completely wash a full load of normally soiled dishes. Additionally, 
AHAM, BSH, and Whirlpool noted that it is difficult to determine which 
cycles use the soil sensor. (AHAM, No. 27 at pp. 4-6; BSH, No 28. at 
pp. 3-4; Whirlpool, No. 26 at p. 1; Whirlpool, 2012 Public Meeting 
Transcript, No. 38 at pp. 88-89) AHAM commented that DOE issued 
guidance in 2010 stating that a soil-sensing cycle is to be used, even 
if the normal cycle is fixed. AHAM stated that to some, this guidance 
changed the interpretation of the test procedure. (AHAM, 2012 Public 
Meeting Transcript, No. 38 at pp. 85-86)
    Additionally, AHAM, BSH, Samsung, and Whirlpool pointed out that a 
manufacturer may make multiple recommendations for cycles that would 
completely wash a full load of normally soiled dishes, which could 
invite manufacturer recommendation of alternative cycles or option 
combinations that could be interpreted by consumers to be alternatives 
to the ``normal cycle''. These commenters stated it is therefore 
logical that the energy test cycle and ``normal cycle'' should be the 
cycle most commonly used by consumers on an everyday basis. 
Accordingly, AHAM, BSH, and Whirlpool suggested that the definition of 
``normal cycle'' be revised to clarify that intent, and to encourage 
manufacturers to recommend cycles to the consumer that are consistent 
with the energy and water use measured by the test procedure. In 
response to the May 2012 SNOPR, they proposed the following definition 
for normal cycle: ``normal cycle means the cycle type recommended by 
the manufacturer for daily, regular, or typical use to completely wash 
a full load of normally soiled dishes, including the power-dry feature. 
If multiple cycles are recommended by the manufacturer for daily, 
regular, or typical use to completely wash a full load of normally 
soiled dishes, the most energy intensive of those recommended cycles 
shall be considered the normal cycle for the purposes of this test 
procedure.'' AHAM and Whirlpool opposed the specification of 
temperature options in the normal cycle definition, but commented that 
if DOE adds temperature options to that definition, DOE should require 
selection of the highest temperature settings in the absence of 
manufacturer recommendations. BSH also supported a requirement to 
select the highest temperature settings in the absence of manufacturer 
recommendations. AHAM and Whirlpool stated that, in the absence of data 
indicating which temperature settings are most representative of actual 
consumer use, consumers could select the highest temperature settings. 
(AHAM, No. 27 at pp. 5-6; AHAM, No. 35 at p. 6; BSH, No. 28 at pp. 3-4; 
BSH, No. 36 at p. 2; Samsung, No. 33 at p. 1; Whirlpool, No. 26 at pp. 
1, 4; Whirlpool, No. 32 at p. 1)
    In response to DOE's updated proposal for the definition of 
``normal cycle'' in the August 2012 SNOPR, AHAM, BSH, Samsung, and 
Whirlpool submitted a revised definition which would state that the 
``[n]ormal cycle means the cycle type recommended in the manufacturer's 
instructions for daily, regular, or typical use to completely wash a 
full load of normally soiled dishes, including the power-dry feature. 
If no cycle or more than one cycle is recommended in the manufacturer's 
instructions for daily, regular, or typical use to completely wash a 
full load of normally soiled dishes, the most energy intensive of these 
cycles shall be considered the normal cycle for purposes of this test 
procedure.'' (AHAM, No. 35 at p. 6; BSH, No. 36 at pp. 2-3; Samsung, 
No. 33 at p. 1; Whirlpool, No. 32 at p. 1)
    Whirlpool commented that DOE should include a ``statement of 
intent'' in the dishwasher test procedure to clarify the test procedure 
for new technology developments, and to prevent manufacturers from 
creating a specifically designed test cycle that fails to perform the 
functions desired by the consumer, similar to a recent refrigerator 
rulemaking. (Whirlpool, No. 26 at pp. 3-4; Whirlpool, No. 32 at pp. 1-
2) Samsung also requested that DOE add a statement of intent to help

[[Page 65964]]

manufacturers, certification bodies, and consumers understand that the 
intent of the energy test cycle selection is to reflect the 
representativeness of the test procedure to consumer use conditions. 
(Samsung, No. 33 at p. 1) According to BSH, however, any additional 
statements of intent and/or additional wording seeking to further 
clarify the definition may, in some cases, result in confusion as to 
what cycle should be selected for testing. (BSH, No. 36 at p. 2)
    Under EPCA, any test procedure for consumer products that DOE 
prescribes or amends shall be reasonably designed to produce test 
results which measure energy consumption or energy efficiency of these 
products during a representative average use cycle or period of use. 
(42 U.S.C. 6293(b)(3)) DOE is aware of products available on the market 
that have multiple cycles recommended by the manufacturer for washing a 
full load of normally soiled dishes, and that for soil-sensing 
dishwasher these cycles may be soil-sensing or non-soil sensing. Upon 
consideration of the arguments put forth by commenters that consumers 
are most likely to select cycles that are recommended by the 
manufacturer when washing a full load of normally soiled dishes, DOE 
determines that it would be contrary to the EPCA requirements if DOE 
were to require the preferential selection of a soil-sensing cycle for 
a soil-sensing dishwasher, regardless of the manufacturer's 
instructions to the consumer. Therefore, DOE agrees with the 
stakeholder recommendation for the definition of normal cycle, 
including the requirement to test on the most energy-intensive of 
multiple recommended cycles or, in the absence of a manufacturer 
recommendation, the most energy-intensive of all cycles. Because the 
most energy-intensive cycle would include the highest energy 
consumption temperature options for washing and drying, DOE includes 
such a clarification in the definition of the normal cycle in appendix 
C1, which would be required to be used on the compliance date of any 
final amended standards for dishwashers (i.e., May 30, 2013 unless the 
direct final rule issued on May 30, 2012 is withdrawn). On that 
compliance date, the definition of normal cycle that DOE adopts in 
today's final rule supersedes the 2010 guidance. For the reasons 
discussed above, DOE withdraws the guidance effective May 30, 2013 
(unless the direct final rule issued on May 30, 2012 is withdrawn, in 
which case the guidance will remain in effect). DOE also clarifies in 
appendix C1 that ``non-soil-sensing dishwasher'' refers to a dishwasher 
that does not have the ability to adjust automatically any energy 
consuming aspect of the normal cycle based on the soil load of the 
dishes, and that a ``soil-sensing-dishwasher'' does have the ability to 
adjust automatically any energy consuming aspect of the normal cycle 
based on the soil load of the dishes. In addition, DOE clarifies that 
soil-sensing dishwashers shall be tested on the normal cycle. 
Furthermore, DOE has not included a statement of intent in the 
amendments to the dishwasher test procedure adopted in today's final 
rule. EPCA's requirement that test procedures measure energy 
efficiency, energy use or water use during a representative average use 
cycle obviates the need for specific clarification of that purpose in 
the residential dishwasher test procedure in the absence of any 
indication that manufacturers are designing products that test under 
conditions different than those used by the consumer.
    AHAM, BSH, and Whirlpool recommend that manufacturers be required 
to submit with their certification reports: (1) Whether the unit is 
soil-sensing; (2) the cycle selected for the energy test; and (3) the 
options selected for the energy test. AHAM also recommended 
manufacturers certify in the report whether the test cycle is soil-
sensing. AHAM, BSH, and Whirlpool suggested that manufacturers include 
a clear recommendation for the cycle setting and options in their use 
and care guides, or on the product controls. (AHAM, No. 27 at p. 6; 
AHAM, 2012 Public Meeting Transcript, No. 38 at p. 87; BSH, No. 28 at 
pp. 4-5; BSH, 2012 Public Meeting Transcript, No. 38 at pp. 91-92; 
Whirlpool, No. 26 at p. 1) Intertek commented that currently, the only 
way for laboratories to know if a unit has a soil sensor is to 
reference the use and care manual. (Intertek, 2012 Public Meeting 
Transcript, No. 38 at p. 91) BSH and Whirlpool indicated that their 
user manuals likely indicate whether a unit has a soil sensor, while GE 
noted their manuals do not necessarily indicate which cycles are soil-
sensing, and which are fixed. (BSH, 2012 Public Meeting Transcript, No. 
38 at p. 92; Whirlpool, 2012 Public Meeting Transcript, No. 38 at p. 
92; GE, 2012 Public Meeting Transcript, No. 38 at p. 98)
    DOE notes that the certification requirements for dishwashers 
included in 10 CFR part 429.19 require manufacturers to report the 
following information for each certified basic model: the capacity in 
number of place settings as specified in ANSI/AHAM DW-1, presence of a 
soil sensor (if yes, the number of cycles required to reach 
calibration), and the water inlet temperature used for testing in 
[deg]F. In today's final rule, DOE determined, for reproducibility of 
the test procedure, to additionally require that manufacturers submit 
the cycle used for energy testing, whether that cycle is soil-sensing, 
and the options selected for that cycle during energy testing.
2. Preconditioning
    In the May 2012 SNOPR, DOE proposed that, for soil-sensing 
dishwashers, the cycle setting for the active mode cycle (in which the 
soil sensor is active) be selected for the preconditioning cycle. 77 FR 
31444, 31452 (May 25, 2012). In the August 2012 SNOPR, DOE additionally 
proposed requiring two preconditioning cycles to ensure the soil sensor 
is properly calibrated, and to clean any debris out of the dishwasher 
prior to testing. 77 FR 49064, 49066 (Aug. 15, 2012).
    AHAM, BSH, Samsung, and Whirlpool agreed with using the test cycle 
for preconditioning, but also commented that the definition of 
preconditioning is vague and not adequate for the way some products 
operate today. They commented that the proposed language may be 
confusing, and recommended that the cycle used for preconditioning be 
the same as the cycles used for the test. (AHAM, No. 27 at p. 9; AHAM, 
No. 35 at p. 7; AHAM, 2012 Public Meeting Transcript, No. 38 at pp. 
107-108; BSH, No. 36 at p. 3; BSH, No. 28 at p. 7; Samsung, No. 33 at 
p. 1; Whirlpool, No. 26 at p. 1; Whirlpool, No. 32 at p. 1) AHAM, BSH, 
Samsung, and Whirlpool also support the requirement for two 
preconditioning cycles. (AHAM, No. 35 at p. 7; BSH, No. 36 at p. 3; 
Samsung, No. 33 at p. 1; Whirlpool, No. 32 at p. 1) Whirlpool and BSH 
commented that some laboratories perform more than one preconditioning 
cycle to ensure that the machine is cleaned out and water usage is 
quantified, although Whirlpool's products are designed so that the 
sensor calibrates in one cycle. Whirlpool acknowledged, however, that 
if its dishwasher does not calibrate in the first cycle, then it uses 
the next cycle as well, and will keep trying on subsequent cycles if 
there is still an error. BSH commented that the action taken if the 
sensor fails to calibrate on the first cycle varies from manufacturer 
to manufacturer. Whirlpool and BSH stated that they have equipment in 
their own laboratories that can determine whether the sensor has 
calibrated, but

[[Page 65965]]

they further noted that there is not a clear way for a third-party 
laboratory to determine whether the sensor had calibrated, because the 
energy and water use that would indicate a calibration process are 
model-specific and the sensor responses are complex. According to BSH, 
sensor responses may include changes in motor speed and water 
temperatures, as well as water consumption. Whirlpool and BSH added 
that their sensors are designed to calibrate with clean water, rather 
than with a soiled load. (BSH, 2012 Public Meeting Transcript, No. 38 
at pp. 111-113, 115-116, 118; Whirlpool, 2012 Public Meeting 
Transcript, No. 38 at pp. 109-115, 117, 119-120) Viking Range 
Corporation (Viking) commented that user manuals typically contain 
energy use information for cycles that would provide an indication to a 
laboratory as to whether a calibration occurred. (Viking, 2012 Public 
Meeting Transcript, No. 38 at pp. 120-121) BSH stated that it provides 
a minimum and maximum water consumption, but water use above the 
maximum is not necessarily indicative of a problem with calibration. 
(BSH, 2012 Public Meeting Transcript, No. 38 at p. 122) UL stated that 
it performs one preconditioning cycle because that is the 
recommendation in ANSI/AHAM DW-1. (UL, 2012 Public Meeting Transcript, 
No. 38 at p. 123)
    DOE has determined that specifying the energy test cycle would 
provide clarity and the most accurate possible water usage measurement 
for calculation of detergent dosing. Thus, in appendix C1 established 
by today's final rule, DOE includes the requirement that the 
preconditioning cycle be conducted using the same cycle setting as the 
energy test cycle, as proposed in the May 2012 SNOPR and August 2012 
SNOPR. DOE has added further clarification by revising the definition 
for ``preconditioning cycle'' to state that it is a normal cycle run 
with no test load to ensure that the water lines and sump area of the 
pump are primed. DOE also determines that there would be a slight 
additional test burden of conducting two preconditioning cycles, but 
that this increase is warranted by the improvement in test measurements 
by ensuring sensor calibration and cleaning out the machine and is not 
unduly burdensome to conduct, as discussed in section III.K. In 
addition, specifying two preconditioning cycles would eliminate the 
need for laboratories to interpret testing data to determine whether 
sensor calibration occurred successfully after the first 
preconditioning, thus improving reproducibility of the test procedure. 
For these reasons, DOE is requiring the use of two preconditioning 
cycles in the dishwasher test procedure established at appendix C1.
3. Detergent
    In the May 2012 SNOPR, DOE proposed determining detergent dosing 
using the pre-wash and main wash fill volumes during the 
preconditioning cycle, and outlined the calculations for the proper 
dosing. Additionally, the proposal updated the type of detergent to the 
currently-available ``Cascade with the Grease Fighting Power of Dawn'' 
powder detergent. 77 FR 31444, 31453 (May 25, 2012). In the August 2012 
SNOPR, DOE continued to propose detergent dosing as outlined in the May 
2012 SNOPR, with the clarification that the pre-wash and main wash fill 
volumes be recorded during the second proposed preconditioning cycle. 
77 FR 49064, 49066 (Aug. 15, 2012).
    AHAM commented that the proposed detergent dosage calculation 
leaves room for interpretation. (AHAM, 2012 Public Meeting Transcript, 
No. 38 at p. 93) AHAM, BSH, and Whirlpool commented that the 
concentration approach for detergent dosing may no longer be 
representative of actual consumer use because consumers are more likely 
to use a monodose detergent. AHAM, BSH, and Whirlpool recommended that 
DOE should base the decision about whether to specify a certain amount 
of powder detergent or a unitized dose such as a tablet on consumer 
usage data, and cited an AC Nielson Homescan Panel study which found a 
trend towards monodose detergents from 2000 to 2011. According to these 
commenters, the study showed that dishwasher detergent usage was 14.5 
percent monodose, 39 percent gel, and 46.5 percent powder in 2000, 
which shifted to 53.5 percent monodose, 28.5 percent gel, and 18 
percent powder in 2011. AHAM, BSH, and Whirlpool stated that a fixed 
detergent dose in the dishwasher test procedure would be more 
representative of consumer usage, less burdensome, and more accurate 
than the powder detergent dosage currently required, which can vary 
from test to test due to its complexity. AHAM and Whirlpool further 
commented that DOE may also consider consumer use of monodose tablets 
including rinse aid. (AHAM, No. 27 at pp. 10-11; BSH, No. 28 at pp. 7-
8; Whirlpool, 2012 Public Meeting Transcript, No. 38 at pp. 94, 96-97; 
Whirlpool, No. 26 at p. 1)
    AHAM, BSH, and Whirlpool commented that DOE should consider whether 
the detergent should be a laboratory formulation or a formulation 
available on the market. (AHAM, No. 27 at p. 10; BSH, No. 28 at pp. 7-
8; Whirlpool, No. 26 at p. 1) BSH proposed that DOE consider an IEC 
test detergent to eliminate variation due to manufacturing tolerances 
and formulation changes. (BSH, No. 28 at p. 8) In the interim, however, 
without a consumer use study, AHAM, BSH, and Whirlpool support DOE's 
proposal to update the detergent requirement to the ``Cascade with the 
Grease Fighting Power of Dawn'' formulation powder detergent. AHAM and 
BSH commented, though, that DOE would need to consider how a phosphate-
free detergent would affect energy and water use results. (AHAM, No. 27 
at p. 10; AHAM, 2012 Public Meeting Transcript, No. 38 at pp. 93-94; 
BSH, No. 28 at p. 8; Whirlpool, No. 26 at p. 1)
    BSH noted that detergent dosing based on the preconditioning cycle 
with a clean load may not reflect the amount of water that would be 
used during a test cycle with a soiled load, and that the food load and 
soil sensors will affect each other. BSH also commented that the 
detergent can influence the sensor decision. (BSH, 2012 Public Meeting 
Transcript, No. 38 at pp. 94-96, 99)
    DOE has determined to adopt the concentration specification for 
``Cascade with the Grease Fighting Power of Dawn'' rather than the 
other detergent dosing methods. A monodose detergent would result in 
the same amount of detergent being dispensed for every dishwasher, 
regardless of water consumption. This may skew test results for 
dishwashers with either high or low water consumption due to the 
changes in detergent concentration that could impact how easily soils 
are removed from the test load. A concentration-based detergent dosing 
ensures that the detergent concentration is similar from unit-to-unit.
    Additionally, DOE does not have any information indicating that 
this phosphate-free detergent would have any impact on energy and water 
use results. DOE notes that the detergent specified in ANSI/AHAM DW-1-
1992 has been unavailable for a number of years. DOE understands that 
manufacturers and third-party test laboratories have used ``Cascade 
with the Grease Fighting Power of Dawn'' in its absence, with no 
apparent impact in the resulting energy and water consumption results.
    DOE acknowledges that the water consumption in the second 
preconditioning cycle with no soil load may be different from the water 
consumed during the test cycle. However, running a soiled load with no 
detergent to determine water consumption may also yield water

[[Page 65966]]

consumptions different from the test cycle due to the lack of detergent 
and less-effective removal of soils from the test load. The method of 
basing detergent dosing on the preconditioning water consumptions helps 
to limit test burden for manufacturers and third-party test 
laboratories. Additionally, the requirement to run the preconditioning 
cycle on the same setting as the test cycles would likely lead to 
similar water consumptions for both preconditioning and testing.
    Therefore, DOE continues to include the concentration-based 
detergent calculation using the pre-wash and main wash water 
consumptions as measured during the second preconditioning cycle, and 
to update the detergent specification to ``Cascade with the Grease 
Fighting Power of Dawn'' for appendix C1 in today's final rule. DOE 
also amends appendix C to specify the detergent as ``Cascade with the 
Grease Fighting Power of Dawn'' because the currently specified 
detergent is no longer available, thereby making such specification 
obsolete.
4. Power Supply Requirements
    In the May 2012 SNOPR, DOE proposed that power be continuously 
supplied to the unit during testing, including after the 
preconditioning cycle and between all test cycles. 77 FR 31444, 31452 
(May 25, 2012). The August 2012 SNOPR updated the proposed continuous 
power supply requirement to also cover the second preconditioning test 
cycle proposed to ensure sensor calibration. 77 FR 49064, 49066 (Aug. 
15, 2012).
    AHAM, BSH, and Whirlpool commented that the requirement to maintain 
the power supply throughout testing would add test burden for 
manufacturers who know that their soil sensors do not lose calibration 
with an interruption in the power supply. The commenters suggested DOE 
add a note to the test procedure that some soil sensors may lose 
calibration, so that third-party test laboratories would be aware of 
this behavior, without including the requirement to maintain the power 
supply. This would allow manufacturers to avoid unnecessary test 
burden. (AHAM, No. 27 at p. 7; BSH, No. 28 at p. 5; Whirlpool, No. 26 
at p. 1)
    DOE understands that maintaining the power supply represents an 
increase in test burden for manufacturers of units whose soil sensors 
do not lose calibration. However, given the difficulty in determining 
whether a soil sensor is calibrated, DOE includes the continuous power 
supply requirement in appendix C1 to ensure consistent testing by 
either a manufacturer or a third-party laboratory.
5. Updated Industry Standard
    In response to the May 2012 SNOPR, AHAM, BSH, and Whirlpool 
commented that DOE should incorporate by reference the most recent 
versions of external test procedures, including ANSI/AHAM DW-1-2009 (or 
the latest version of DW-1 at the time DOE updates its incorporation by 
reference). These commenters stated that DOE would need to determine 
whether this change would result in changes to measured energy 
(resulting from a change in dishware, for example). AHAM and Whirlpool 
also noted that there are differences in the food soils specified, 
although Whirlpool characterized them as ``fairly subtle.'' (AHAM, No. 
27 at pp. 12-13; AHAM, 2012 Public Meeting Transcript, No. 38 at pp. 
155-156; BSH, No. 28 at p. 10; BSH, 2012 Public Meeting Transcript, No. 
38 at p. 156; Whirlpool, No. 26 at pp. 1, 5; Whirlpool, 2012 Public 
Meeting Transcript, No. 38 at p. 156)
    In response to these comments, for the August 2012 SNOPR, DOE 
proposed to update the industry standard test reference in appendix C 
from ANSI/AHAM DW-1-1992 to DW-1-2010. 77 FR 49064, 49066 (Aug. 15, 
2012).
    AHAM, BSH, Samsung, and Whirlpool support the proposal to update 
the industry standard reference to ANSI/AHAM DW-1-2010, but noted they 
do not currently have data on the effect on energy use of changing to 
the updated version of the standard. These commenters stated that DOE 
must determine whether there would be changes to the measured energy 
use. (AHAM, No. 35 at pp. 7-8; BSH, No. 36 at p. 3, Samsung, No. 33 at 
p. 1; Whirlpool, No. 32 at p. 1)
    The DOE dishwasher test procedure references certain sections of 
ANSI/AHAM DW-1 related to soil preparation and application. Differences 
in other provisions such as the dishware specifications would not 
impact the measurement of energy and water use under the DOE test. When 
DOE compared the relevant sections of 1992 and 2010 versions of the 
standard, it identified the following differences:
     The brand and product description for the coffee and 
preserves;
     The preparation method for the eggs and cream corn;
     The amount of reconstituted milk used in the potato 
mixture;
     The grinding specifications for the ground beef; and
     The order of soil application.
    DOE has not been presented with any data or information that would 
show that these differences would impact the results from the DOE 
dishwasher test procedure for specific dishwasher models. DOE also 
notes the uniform support from commenters to reference the most recent 
version of industry standards in its test procedures and observes that 
some test laboratories are already conducting dishwasher testing 
according to ANSI/AHAM DW-1-2010. Further, these amendments will not be 
required until the compliance date of new standards, which will be May 
30, 2013, unless the direct final rule is withdrawn. If manufacturers 
determine that the new DOE test procedure does not measure energy and 
water use that is representative for their products, they may submit to 
DOE a petition for waiver from the DOE test procedure to determine an 
appropriate method. For the reasons discussed above, DOE has decided to 
update the reference in its dishwasher test procedure at appendix C1 to 
ANSI/AHAM DW-1-2010 in today's final rule.
6. Water Pressure
    As noted in the August 2012 SNOPR, DOE received comments in 
response to the May 2012 SNOPR regarding transient water pressure drop 
when the water supply valve first opens. AHAM, BSH, and Whirlpool 
commented that laboratories interpret differently how and where the 
water pressure is measured and controlled. These commenters recommended 
that, for repeatability and reproducibility, DOE should specify that 
the water pressure drops to the required 35 pounds per square inch 
gauge (psig)  2.5 psig in no more than 2 seconds after the 
valve opens. According to AHAM, its members and independent 
laboratories indicated that this is the minimum length of time that 
they are capable of achieving. (AHAM, No. 27 at p. 12; AHAM, 2012 
Public Meeting Transcript, No. 38 at p. 137; BSH, No. 28 at p. 9; BSH, 
2012 Public Meeting Transcript, No. 38 at p. 158; Whirlpool, No. 26 at 
p. 1) Samsung noted that the time for the transient pressure drop 
should be minimized so that it does not affect a water fill, since the 
fill time can be approximately 1 minute. (Samsung, 2012 Public Meeting 
Transcript, No. 38 at pp. 139-140) According to Whirlpool, the height 
at which the pressure measurement is made affects the measurement, 
although not significantly. (Whirlpool, 2012 Public Meeting Transcript, 
No. 38 at p. 137)
    In the August 2012 SNOPR, DOE acknowledged that transient pressure 
variations should be minimized for reasons of test stability and 
reproducibility, and, based on

[[Page 65967]]

commenters' indication of laboratory capabilities, proposed that the 
specified pressure be achieved within 2 seconds. 77 FR 49064, 49066 
(Aug. 15, 2012). AHAM, BSH, Samsung, and Whirlpool supported this 
proposal, reiterating that the duration of the pressure drop should be 
limited to ensure that water is flowing into the dishwasher at the 
proper pressure and that AHAM's members indicated that 2 seconds is the 
minimum length of time their laboratories can achieve. (AHAM, No. 35 at 
p. 8; BSH, No. 36 at p. 3, Samsung, No. 33 at p. 1; Whirlpool, No. 32 
at p. 1)
    In consideration of these comments and for the reasons already 
noted, DOE adopts in today's final rule the requirement in the new 
dishwasher test procedure that the water pressure shall be achieved 
within 2 seconds of opening the water supply valve. DOE is not 
requiring the pressure to be measured at a particular location because 
DOE did not receive sufficient information regarding a representative 
position or the impact of pressure measurement position on the energy 
and water use results.
7. Water Hardness
    DOE received comments in response to the May 2012 SNOPR and the 
August 2012 SNOPR that DOE should add a water hardness specification to 
the dishwasher test procedure. AHAM, BSH, Samsung and Whirlpool 
commented that DOE should reference the water hardness specification in 
ANSI/AHAM DW-1-2010 of 0 to 5 grains, or 0 to 85 ppm, to reduce test 
variation. (AHAM, No. 27 at p. 11; AHAM, No. 35 at p. 10; BSH, No. 28 
at p. 9; Samsung, No. 33 at p. 1; Whirlpool, No. 26 at pp. 1, 5) AHAM 
and Whirlpool further clarified that the American Water Works 
Association found this to be the normal range occurring in municipal 
water supplies, and Whirlpool stated that the water hardness 
specification was intended to reduce lab-to-lab test variation. (AHAM, 
No. 27 at p. 11; Whirlpool, No. 26 at p. 1; Whirlpool, 2012 Public 
Meeting Transcript, No. 38 at pp. 148-150) Whirlpool later changed its 
recommendation for a water hardness requirement to a range of 0 to 2 
grains, or 0 to 34 ppm, based on total hardness and not just calcium 
carbonate, to account for magnesium as well. According to Whirlpool, 
laboratories can control water hardness to this range with water 
softening systems. (Whirlpool, No. 34 at p. 2) UL commented that 
varying between soft and hard water could potentially impact test 
results. (UL, 2012 Public Meeting Transcript, No. 38 at p. 151) AHAM 
noted that in the process of developing an ENERGY STAR test method for 
dishwasher cleaning performance, DOE proposed to adopt the water 
hardness requirement in ANSI/AHAM DW-1-1992. (AHAM, 2012 Public Meeting 
Transcript, No. 38 at pp. 146-147)
    DOE proposed a water hardness requirement as part of the ENERGY 
STAR test method for evaluating dishwasher cleaning performance because 
it may have an impact on cleaning performance. However, DOE is not 
aware of data indicating how variations in water hardness may impact 
energy and water consumption under the DOE test procedure, and, 
therefore, is not adopting a water hardness requirement in the test 
procedure at this time. DOE may consider this topic in a future 
rulemaking if such data become available.
8. Drain Height
    AHAM noted at the 2012 Public Meeting that the height of the 
dishwasher drain is not currently specified in the DOE test procedure, 
and that such a specification should be added to reduce testing 
variability. AHAM, BSH, and Whirlpool subsequently proposed in their 
comments on the May 2012 SNOPR that the drain height should be 
specified per the manufacturer installation instructions. In the 
absence of such instructions, these commenters recommended a drain 
height of 20 inches. (AHAM, No. 27 at p. 11; AHAM, 2012 Public Meeting 
Transcript, No. 38 at p. 141; BSH, No. 28 at pp. 8-9; Whirlpool, No. 26 
at p. 1)
    In the August 2012 SNOPR, DOE agreed that the use of manufacturer's 
instructions for drain height, or a standard height in the absence of 
such information, would improve reproducibility of the test and 
proposed corresponding amendments to the dishwasher test procedure, 
including a standard drain height of 20 inches. 77 FR 49064, 49066 
(Aug. 15, 2012).
    AHAM, BSH, Samsung, and Whirlpool supported the proposed approach 
to require installation of the dishwasher with a drain height as 
specified in the manufacturer's instructions, and that in the absence 
of such instructions, the drain height should be a standard level of 20 
inches. (AHAM, No. 35 at p. 8; BSH, No. 36 at p. 3; Samsung, No. 33 at 
p. 1; Whirlpool, No. 32 at p. 1) For reasons of test reproducibility 
and in the absence of comments objecting to this approach, DOE includes 
the drain height requirements in the new dishwasher test procedure in 
today's final rule according to the proposal in the August 2012 SNOPR.
9. Test Load Specifications and Soiling Requirements, Including 
Obsolete Dishware and Food Items
    In the May 2012 SNOPR, DOE observed that the requirement for soil-
sensing dishwashers in the current DOE test procedure to soil a certain 
number of place settings, while leaving the remaining place settings, 
serving pieces, and all flatware in the test load unsoiled could be 
ambiguous because the test procedure does not define which items a 
``place setting'' comprises. Therefore, DOE proposed to amend section 
2.7 of appendix C to specify the individual items in a place setting 
and to identify the serving pieces, as well as to clarify in section 
2.6.3 of appendix C that the flatware that is part of a soiled place 
setting is to remain unsoiled. 77 FR 31444, 31453 (May 25, 2012). DOE 
maintained this proposal for the August 2012 SNOPR. AHAM, BSH, and 
Whirlpool commented that the test procedure was already clear in 
requiring that the flatware is not to be soiled, but did not object to 
the proposed clarification. (AHAM, No. 27 at pp. 7-8; BSH, No. 28 at p. 
6; Whirlpool, No. 26 at p. 1) DOE has therefore included these 
amendments to section 2.7 and 2.63 of the new dishwasher test procedure 
at appendix C1 in today's final rule.
    In the May 2012 SNOPR, DOE also identified a number of test items, 
including the cup and saucer, salad fork, serving fork, and serving 
spoon, which are no longer available, thereby making such 
specifications obsolete. DOE noted that AHAM had submitted information 
providing alternative specifications for all flatware and serving 
pieces, which DOE proposed as amendments to the test load 
specifications in section 2.7 of appendix C. DOE also sought comment on 
alternative specifications for other obsolete test items, such as the 
cup and saucer.
    AHAM, BSH, and Whirlpool noted the importance to manufacturers and 
third-party laboratories of identifying replacement test load items 
swiftly to run the test and certify compliance properly. AHAM and BSH 
supported DOE's proposal for replacements to obsolete flatware and 
serving pieces. AHAM and BSH noted, however, that although the cup and 
saucer are obsolete, alternatives may be available from the same source 
but with a new item number. These commenters also suggested that the 
bread and butter plate and fruit bowl may become obsolete. (AHAM, No. 
27 at pp. 7-8; BSH, No. 28

[[Page 65968]]

at pp. 5-6; Whirlpool, No. 26 at pp. 1, 5)
    In addition to comments on the obsolete test load items, DOE 
received comments on obsolete food items for the soil requirements. 
AHAM, BSH, and Whirlpool stated that the margarine specified in the 
current dishwasher test procedure was no longer available, and proposed 
a replacement brand and product formulation even though it is not 
possible to determine if the replacement margarine would impact 
measured energy use. (AHAM, No. 27 at p. 8; AHAM, 2012 Public Meeting 
Transcript, No. 38 at pp. 101-102; BSH, No. 28 at p. 6; BSH, 2012 
Public Meeting Transcript, No. 38 at pp. 102-103; Whirlpool, No. 26 at 
p. 1; Whirlpool, 2012 Public Meeting Transcript, No. 38 at pp. 103, 
129)
    For the August 2012 SNOPR, DOE considered these comments, and based 
on these and additional research, proposed the items shown below in 
Table 1 as replacements for obsolete or nearly obsolete items. 77 FR 
49064, 49065 (Aug. 15, 2012).

------------------------------------------------------------------------

    AHAM, BSH, Samsung, and Whirlpool support the proposed replacement 
items for the flatware, serving pieces, and food items, including the 
margarine and coffee. (AHAM, No. 35 at pp. 2-3; BSH, No. 36 at p. 2; 
Samsung, No. 33 at p. 1; Whirlpool, No. 32 at p. 1) Therefore, DOE 
adopts these replacement flatware, serving pieces, and food items in 
the amendments to appendix C procedure in today's final rule. DOE also 
includes these replacement items in the new dishwasher test procedure 
at appendix C1.
    For the dishware replacements, AHAM, BSH, Samsung, and Whirlpool 
noted that, although the primary cups and saucers specified in the test 
procedure are obsolete, the alternate Arzberg items specified are still 
available, albeit with new product numbers. The alternate cup, Arzberg 
product number 3824732100, currently specified in the dishwasher test 
procedure is now designated as product number 1382 00001 4732. The 
alternate saucer, Arzberg product number 3824731100, currently 
specified in the dishwasher test procedure is now designated as product 
number 1382 00001 4731. Because the shapes of DOE's proposed 
replacement cup and saucer are different than for the existing 
alternate Arzberg cup saucer and it is not known how these differences 
could affect the test results, these commenters recommend not adopting 
DOE's proposal for the cup and saucer. Instead, they suggest that DOE 
designate the current alternate Arzberg cup saucer, identified by their 
new product numbers, as the primary items and not specify alternates. 
AHAM, BSH, Samsung, and Whirlpool further commented that DOE's proposed 
replacement cup and saucer could potentially be acceptable alternates, 
but manufacturers would first need to assess the impacts of such 
variables as the weight of the items and the ability of various rack 
designs to accommodate them. These commenters stated that it would be 
ideal for at least one option for the cup and saucer to be sourced from 
within the United States in order to minimize burden. (AHAM, No. 35 at 
pp. 3-4; BSH, No. 36 at p. 2; Samsung, No. 33 at p. 1; Whirlpool, No. 
32 at p. 1)
    DOE has ascertained that the alternate cup and saucer currently 
specified in the DOE test procedure are available for purchase at this 
time under the different item numbers identified by commenters. 
Therefore, for consistency in the dishwasher test results, DOE amends 
the dishwasher test procedure in today's final rule to specify the 
current alternate Arzberg cup and saucer by their new product numbers 
as the alternate test load items. DOE reconsidered its proposal to 
eliminate the specifications for the obsolete Corning Comcor/Corelle 
cup and saucer, and instead retains these as the primary test load 
items so that manufacturers and testing laboratories may continue to 
use items they may already possess. DOE also includes these replacement 
item specifications in the new dishwasher test procedure at appendix 
C1. If DOE receives additional information regarding dishwasher energy 
and water consumption using the Arzberg replacement cup and saucer 
proposed in the August 2012 SNOPR, or other alternatives suggested by 
interested parties, DOE may consider updating the test procedure at 
that time so that additional options for the cup and saucer are 
available to manufacturers and testing laboratories.
    For the bread and butter plate, AHAM, BSH, Samsung, and Whirlpool 
agreed that the existing Corning Comcor/Corelle test item be retained. 
In addition, these commenters agreed with the proposed Arzberg 
replacement item, product number 2000 00001 0217 1, as an alternate 
item, but noted that it may actually be the redesignated product number 
for the existing Arzberg alternate bread and butter plate, product 
number 8500217100. These commenters recommend that DOE list both 
product

[[Page 65969]]

numbers as alternates in the dishwasher test procedure so that testing 
can continue until it is verified whether the products are the same. 
(AHAM, No. 35 at p. 5; BSH, No. 36 at p. 2; Samsung, No. 33 at p. 1; 
Whirlpool, No. 32 at p. 1)
    DOE agrees with that the approach will minimize impact on 
manufacturers and testing laboratories, and adopts in today's final 
rule specifications for the two Arzberg bread and butter plate product 
numbers as allowable alternate test load items in appendix C and 
appendix C1.
    For the fruit bowl, AHAM, BSH, Samsung, and Whirlpool agreed with 
DOE's proposal to retain the existing primary Corning Comcor/Corelle 
specification but objected to DOE's proposed Arzberg additional 
alternate specification. The commenters stated that the additional 
replacement fruit bowl is significantly larger than the existing fruit 
bowl, so there could be an impact on measured energy use due to the 
weight difference and ability for the bowl to fit into racks. However, 
the commenters did not provide a suggestion for a recommended 
replacement for the alternate fruit bowl. (AHAM, No. 35 at p. 5; BSH, 
No. 36 at p. 2; Samsung, No. 33 at p. 1; Whirlpool, No. 32 at p. 1)
    DOE acknowledges that the impact of a fruit bowl that is larger 
than the item currently specified in the dishwasher test procedure is 
not known. Therefore, for consistency in the dishwasher test results, 
DOE does not adopt the proposed Arzberg replacement fruit bowl as an 
additional alternate test load item in today's final rule. DOE also 
reconsidered its proposal to eliminate the specifications for the 
obsolete Arzberg fruit bowl currently specified as the alternate item, 
and instead retains this product as an alternate test load item in both 
appendix C and appendix C1 so that manufacturers and testing 
laboratories may continue to use items they may already possess. If DOE 
receives additional information regarding dishwasher energy and water 
consumption while using the Arzberg replacement fruit bowl proposed in 
the August 2012 SNOPR, or another alternative suggested by interested 
parties, DOE may consider updating the test procedure at that time so 
that additional options for the fruit bowl are available to 
manufacturers and testing laboratories.
    In response to the May 2012 SNOPR, DOE also received comments that 
DOE should clarify in the dishwasher test procedure the length of time 
that soils may sit or be stored before they are applied to the 
dishware. AHAM, BSH, and Whirlpool stated that potatoes will get 
stiffer the longer they sit, and proposed that prepared potatoes should 
be used within 30 minutes of preparation. AHAM and Whirlpool also noted 
that oatmeal settles and thus proposed that it should be prepared and 
applied as specified in both ANSI/AHAM DW-1-1992 and ANSI/AHAM DW-1-
2010; i.e., the oatmeal should stand for 1 minute after preparation and 
then be used immediately. Whirlpool noted that the length of time that 
the prepared oatmeal sits could cause variability in the test 
procedure. AHAM, BSH, and Whirlpool additionally recommended that the 
reconstituted milk should be allowed to be stored for use over the 
course of a day, and that the prepared one-pound packages of beef be 
allowed to be stored in a freezer for up to 6 months to minimize 
variability in the test procedure. (AHAM, No. 27 at pp. 8-9; BSH, No. 
28 at p. 6; Whirlpool, No. 26 at p. 1; Whirlpool, 2012 Public Meeting 
Transcript, No. 38 at p. 128)
    In the August 2012 SNOPR, DOE proposed to amend the dishwasher test 
procedure to require the potatoes to be used within 30 minutes of 
preparation and the reconstituted milk be allowed to be stored for use 
over the course of 1 day, as recommended by commenters. DOE's proposal 
also included provisions for reconstituting the milk. DOE additionally 
proposed to adopt the commenters' recommendation that the 1-pound 
packages of ground beef shall be stored frozen for no more than 6 
months. DOE determined that the instructions contained within the 
referenced sections of both versions of ANSI/AHAM DW-1 pertaining to 
soil preparation and application, which are or were proposed to be 
referenced in appendix C, are sufficiently clear in requiring the 
prepared oatmeal to sit no longer than 1 minute before using. 
Therefore, DOE did not propose any clarifications in the August 2012 
SNOPR for the oatmeal preparation. 77 FR 49064, 49067 (Aug. 15, 2012).
    AHAM, BSH, Samsung, and Whirlpool support DOE's proposed 
clarifications to the soil preparation and storage requirements for 
potatoes, reconstituted milk, and ground beef, even though these 
commenters added that manufacturer's instructions for reconstituting 
the milk could change. The commenters also reiterated their 
recommendation that the dishwasher test procedure specifically require 
that the oatmeal be prepared and used consistent with ANSI/AHAM DW-1-
1992 and 2009. (AHAM, No. 35 at p. 9; BSH, No. 36 at p. 3; Samsung, No. 
33 at p. 1; Whirlpool, No. 32 at p. 1) Viking commented that it was 
aware of outside laboratories that do not put water into the milk 
formulation directly and measure dry milk into the oatmeal mixture. 
(Viking, 2012 Public Meeting Transcript, No. 38 at p. 133)
    For the reasons stated above, and consideration of comments 
expressing support, DOE is revising the soil preparation and storage 
provisions for potatoes, reconstituted milk, and ground beef for the 
new dishwasher test procedure in today's final rule as proposed in the 
August 2012 SNOPR. DOE also clarifies in appendix C1 that the nonfat 
dry milk shall be reconstituted with water before mixing with the 
oatmeal and potatoes. DOE notes that the referenced section 5.5 of 
ANSI/AHAM DW-1-2010 pertaining to soil preparation explicitly requires 
that the oatmeal mixture be allowed to stand for 1 minute after mixing, 
then used immediately. Thus the instructions the commenters seek 
regarding the use of the oatmeal mixture are incorporated by reference 
in today's new dishwasher test procedure without requiring additional 
clarification.
    AHAM commented that there have been some questions about the use of 
a brush versus a spatula for soiling the dishes because ANSI/AHAM DW-1-
1992 references utensils, but does not provide specific details beyond 
the order of the soil application. (AHAM, 2012 Public Meeting 
Transcript, No. 38 at p. 127) In today's final rule, DOE updates the 
industry test method in appendix C1 from the previous ANSI/AHAM DW-1-
1992 to ANSI/AHAM DW-1-2010. DOE notes that the newer version of this 
standard includes clarification as to which soils should be spread with 
a spatula or brush.
    BSH and Whirlpool commented that DOE should harmonize these changes 
with the Canadian test method because Canada may have different 
interpretations than DOE. (BSH, 2012 Public Meeting Transcript, No. 38 
at p. 107; Whirlpool, 2012 Public Meeting Transcript, No. 38 at p. 107)
    DOE is aware of the Canadian test procedure, which is similar to 
the DOE test procedure in appendix C. To DOE's knowledge, the proposed 
substitutions and soiling times represent an industry consensus on 
these issues, and therefore are appropriate additions to the DOE test 
procedure regardless of the Canadian interpretation. Additionally, the 
substitute materials available in the United States may differ from 
those available in Canada. As a result, DOE has included the proposed 
substitutions and soiling times in today's amendments.

10. Rack Position and Loading
    DOE received comments in response to the May 2012 SNOPR which 
indicated that the rack position and loading pattern for the test load 
should be specified in the dishwasher test procedure. AHAM, BSH, and 
Whirlpool stated that the position of the upper rack can affect water 
pressure during a test, which BSH and Whirlpool felt could influence 
the rate at which food soils fall off the test load and the turbidity 
sensor decisions. AHAM, BSH, and Whirlpool recommended that for the 
energy test, the upper rack should be in the position recommended by 
the manufacturer, or, in the absence of such a recommendation, in the 
as-shipped position to reduce potential test variation. (AHAM, No. 27 
at p. 11; AHAM, 2012 Public Meeting Transcript; No. 38 at pp. 141-142; 
BSH, No. 28 at p. 9; BSH, 2012 Public Meeting Transcript; No. 38 at pp. 
143-144; Whirlpool, No. 26 at p. 1; Whirlpool, 2012 Public Meeting 
Transcript, No. 38 at p. 145) Intertek stated that it tests dishwashers 
with the rack in the as-shipped position, while UL commented that it 
tests according to the manufacturer instructions. (Intertek, 2012 
Public Meeting Transcript, No. 38 at p. 146; UL, 2012 Public Meeting 
Transcript, No. 38 at p. 151) According to BSH, rack position varies 
from product-to-product. Different platforms may have the same as-
shipped position for the racks, yet have different manufacturer 
recommendations in the user manuals. (BSH, 2012 Public Meeting 
Transcript, No. 38 at p. 144) Furthermore, AHAM stated that the as-
shipped position of the rack for a particular model may not always be 
the same. (AHAM, 2012 Public Meeting Transcript, No. 38 at p. 143)
    AHAM, BSH, and Whirlpool commented that it is difficult to 
standardize loading patterns due to varying rack designs. These 
commenters stated DOE should require a loading pattern according to the 
manufacturer's recommendation. The commenters further stated that the 
unsoiled dishes should be loaded first to settle the loading 
arrangement, and then the appropriate number of unsoiled dishes should 
be replaced with soiled ones in an alternating pattern, avoiding 
placing all soiled dishes in one grouped area or in the corners of the 
racks. AHAM, BSH, and Whirlpool pointed out that this method is similar 
to what DOE proposed in its first draft performance test procedure for 
ENERGY STAR. (AHAM, No. 27 at p. 9; BSH, No. 28 at p. 7; Whirlpool, No. 
26 at p. 1)
    In the August 2012 SNOPR, DOE proposed amendments to the dishwasher 
test procedure that would require adjusting the rack position according 
to the manufacturer recommendations and loading the soiled dishes 
according to section 5.8 of ANSI/AHAM DW-1-2010, which specifies 
loading the dishware in accordance with manufacturer's recommendation, 
following the loading pattern provided in the manufacturer's use and 
care guide, without nesting the dishware or flatware. DOE concluded 
that these proposed amendments would improve test repeatability and 
reproducibility. 77 FR 49064, 49066-67 (Aug. 15, 2012).
    AHAM, BSH, Samsung, and Whirlpool supported the requirement that 
the rack be positioned according to manufacturer recommendations for 
washing a full load of normally soiled dishes. But they further 
recommended that DOE specify that, in the absence of a manufacturer 
recommendation regarding rack position for the normal cycle, the rack 
shall be positioned in the as-shipped position. (AHAM, No. 35 at p. 8; 
BSH, No. 36 at p. 3; Samsung, No. 33 at p. 1; Whirlpool, No. 32 at p. 
1) DOE notes that, although AHAM had also indicated in response to the 
May 2012 SNOPR that the as-shipped position may vary for a particular 
model, it is likely that in such instances, manufacturers would provide 
instructions as to the appropriate rack placement during operation. 
Furthermore, it is likely that a dishwasher that does not provide 
instructions regarding rack position would be shipped with the rack in 
a position suitable for washing a full load of normally soiled dishes. 
Therefore, to provide clarity to testing laboratories regarding rack 
position for both situations, DOE adopts in today's final rule for 
appendix C1 the instructions to install the dishwasher with the rack 
positioned according to manufacturer instructions for washing a full 
load of normally soiled dishes, and that in the absence of such 
instructions, the rack shall be maintained in the as-shipped position.
    AHAM, BSH, Samsung, and Whirlpool reiterated that dish loading is a 
potential source for variation, and that it is difficult to achieve 
standardization of loading patterns because rack designs vary. The 
commenters also noted that DOE did not propose specifications for how 
the soiled items are to be distributed when loaded (i.e., all 
positioned together or alternating with the unsoiled items.) Thus, 
AHAM, BSH, Samsung, and Whirlpool recommend a loading pattern according 
to the manufacturer's recommended loading pattern, with addition 
specification that the unsoiled dishes be loaded first to settle the 
loading arrangement, and then the appropriate number of unsoiled dishes 
be replaced with soiled ones with soiled and unsoiled dishes 
alternating. The commenters would further recommend that testers should 
avoid placing all soiled dishes in one grouped area or in the corners 
of the racks. AHAM, BSH, Samsung, and Whirlpool again noted these 
instructions would be similar to those proposed in the first draft 
ENERGY STAR test method for dishwasher performance, and they encouraged 
DOE to harmonize the loading requirements in appendix C and the future 
ENERGY STAR test method. (AHAM, No. 35 at p. 10; BSH, No. 36 at p. 3; 
Samsung, No. 33 at p. 1; Whirlpool, No. 31 at p. 1)
    DOE is not aware of, nor did commenters provide, data indicating 
whether the loading arrangement of dishes may impact the measured 
energy and water consumption of a particular dishwasher, but notes that 
the loading requirements proposed in the August 2012 SNOPR, which 
reference section 5.8 of ANSI/AHAM DW-1-2010 and accordingly its 
requirement to follow the manufacturer's instructions, do not generally 
preclude testing using an alternating loading pattern of soiled and 
clean dishware. However, some manufacturer's instructions could 
conflict with specific requirements for the location of the soiled 
items. For example, the manufacturer may recommend that the most 
heavily soiled items be placed in a certain location on the rack, which 
would conflict with the instructions to alternate soiled and clean 
items. For these reasons, DOE is not adding in today's final rule any 
additional loading instructions in the dishwasher test procedure beyond 
those specified in section 5.8 of ANSI/AHAM DW-1-2010.
11. Rinse Aid Container
    The dishwasher test procedure precludes the use of rinse aid during 
testing, including preconditioning. However, AHAM, BSH, and Whirlpool 
commented in response to the May 2012 SNOPR that some third-party 
laboratories fill the rinse aid container before the starting the 
energy test cycle, presumably to prevent an indicator light from 
turning on during the test. These commenters believe that DOE should 
clarify that the rinse aid container should not be filled with water. 
According to BSH, the added water creates a thermal mass that must be 
heated when the dishwasher is operated, which would result in higher

[[Page 65971]]

energy use. AHAM, BSH, and Whirlpool stated that if the indicator light 
does turn on, its energy use should be measured. (AHAM, No. 27 at p. 
11; AHAM, 2012 Public Meeting Transcript, No. 38 at pp. 135-136; BSH, 
No. 28 at p. 8; BSH, 2012 Public Meeting Transcript, No. 38 at p. 136; 
Whirlpool, No. 26 at p. 1)
    DOE agreed with commenters, and for reasons of consistency in 
testing, proposed in the August 2012 SNOPR amendments to the dishwasher 
test procedure that would clarify that the rinse aid container should 
not be filled with water for energy testing. 77 FR 49064, 49067 (Aug. 
15, 2012). AHAM, BSH, Samsung, and Whirlpool agreed with this proposal. 
(AHAM, No. 35 at p. 8; BSH, No. 36 at p. 3; Samsung, No. 33 at p. 1; 
Whirlpool, No. 32 at p. 1) DOE adopts in today's final rule this 
provision for the new dishwasher test procedure to ensure 
reproducibility of results.
12. Technical Corrections
    In the May 2012 SNOPR, DOE noted that in sections 5.4.1 and 5.4.2 
of the current dishwasher test procedure, water energy consumption is 
calculated as specified for both non-soil-sensing and soil-sensing 
dishwashers using electrically heated water ``[f]or the normal and 
truncated normal test cycle.'' Because the normal and truncated normal 
test cycles do not apply to soil-sensing dishwashers, DOE proposed to 
remove this qualification in newly designated sections 5.5.1.1 and 
5.5.2.1. Similarly, in sections 5.5.1 and 5.5.2 of the current 
dishwasher test procedure, water energy consumption is calculated as 
specified for both non-soil-sensing and soil-sensing dishwashers using 
gas-heated or oil-heated water ``[f]or each test cycle.'' Because for 
soil-sensing dishwashers the calculation is applied to a single 
weighted-average water consumption measured over the sensor heavy 
response, sensor medium response, and sensor light response cycles, 
this qualification may cause confusion. Therefore, DOE proposed to 
remove this qualification in newly designated sections 5.6.1.1 and 
5.6.2.1. DOE also proposed to correct references to the water 
consumption values used in the calculation of water energy consumption 
in these sections of the dishwasher test procedure, so that separate 
references are provided for non-soil-sensing and soil-sensing 
dishwashers. 77 FR 31444, 31454 (May 25, 2012).
    In addition, DOE stated in the May 2012 SNOPR that, due to a 
transcription error in publication, the September 2011 SNOPR 
erroneously specified in the regulatory text for the proposed 
dishwasher test procedure amendments the calculation of estimated 
annual operating cost for dishwashers having a truncated normal cycle 
which operate at 50[emsp14][deg]F inlet water temperature. 
Specifically, the calculation proposed in 10 CFR 430.23(c)(1)(i)(B) 
contained extraneous variables ``B'' and ``V.'' DOE proposed, 
therefore, in the May 2012 SNOPR to remove these extraneous variables 
to correct the calculation. 77 FR 31444, 31455 (May 25, 2012). DOE 
maintained these proposals in the August 2012 SNOPR.
    AHAM, BSH, and Whirlpool commented that they did not oppose these 
two technical corrections to the dishwasher test procedure. (AHAM, No. 
27 at p. 13; BSH, No. 28 at p. 10; Whirlpool, No. 26 at p. 1) For the 
reasons explained above, DOE adopts in today's final rule the 
corrections to water energy consumption provisions in both the new and 
currently applicable dishwasher test procedures. DOE also adopts the 
corrected calculation described above in its amendments to 10 CFR 
430.23(c).
    Whirlpool commented that DOE should revise its proposal in the May 
2012 SNOPR for section 4.1.2 in the dishwasher test procedure to 
specify that VWSavg is defined as the average of 
VWS,1 and VWS,2. (Whirlpool, No. 26 at p. 1) 
These variables represent the water consumption measured during test 
cycles performed to determine the water use associated with water 
softener regeneration. In the initial portion of the test, two test 
cycles are run, and the water consumption measured for each 
(VWS,1 and VWS,2) are compared. If the difference 
in water consumption between the two cycles is greater than 10 percent, 
the cycle in which the larger water use occurred is deemed to contain a 
water softener regeneration event. The water consumption associated 
with a cycle containing a water softener regeneration event 
(VWSmax) is, under these conditions, the larger of 
VWS,1 and VWS,2. The smaller of VWS,1 
and VWS,2 would be deemed to represent a typical non-water 
softener regeneration cycle, denoted by VWSavg. DOE proposed 
this terminology because, if a water softener regeneration event 
doesn't occur in the first two test cycles, additional cycles are run, 
with the water consumption for each new cycle being compared to the 
average of water consumptions for the previous cycles. Averaging the 
water consumptions for the non-water softener regeneration cycles would 
decrease variation in the test procedure results. Because 
VWSavg represents a typical non-water softener regeneration 
cycle, not a numerical average of VWS,1 and 
VWS,2, DOE did not alter its proposal for the August 2012 
SNOPR as Whirlpool suggested, nor is it adopting such a revision to the 
provisions in the new dishwasher test procedure established in today's 
final rule because the water consumption for water softener 
regeneration shall be a value reported by the manufacturer.
    In the May 2012 SNOPR, DOE inadvertently proposed in section 4.4.2 
of the dishwasher test procedure language that refers to section 1.11 
of the test procedure. DOE corrected that proposal in the August 2012 
SNOPR to properly refer to section 1.13. DOE includes section 4.2.2 of 
appendix C1 in today's final rule according to the August 2012 SNOPR.

I. Incorporation by Reference of an Updated AHAM Dehumidifier Test 
Procedure

    In the May 2012 SNOPR, DOE proposed updating the dehumidifier test 
procedure to clarify which version of the AHAM test method 
``Dehumidifiers'' (DH-1) should be used for testing. DOE evaluated both 
DH-1-1992 and DH-1-2008, and concluded that both versions would produce 
comparable results for the DOE dehumidifier test procedure. However, 
DOE proposed referencing the newer version, DH-1-2008, for both the 
capacity and EF measurements because it provides additional clarity and 
specificity that may improve test accuracy, repeatability, and 
reproducibility. DOE also proposed removing the reference to the ENERGY 
STAR qualification criteria for determining EF, given that the EF 
methodology is included in DH-1-2008. 77 FR 31444, 31453-54 (May 25, 
2012). DOE maintained this proposal for the August 2012 SNOPR.
    AHAM, BSH, and Whirlpool support DOE's proposal to incorporate by 
reference ANSI/AHAM DH-1-2008 for the measurement of capacity and EF, 
and the calculation of IEF, in its dehumidifier test procedure. The 
commenters stated that clarity and consistency for regulated parties is 
critical so that all regulated and other parties (e.g., third-party 
laboratories, DOE, EPA) are testing per the same test procedure; 
therefore, they believe it is important that DOE clarify which version 
of DH-1 it intends to reference in its test procedure. AHAM, BSH, and 
Whirlpool commented that, to their knowledge, there is no difference in 
the measured energy between versions of DH-1, but each version contains 
important technical improvements and clarifications, making the most 
current version of the standard the best one to reference. (AHAM, No. 
27 at p. 13; BSH,

[[Page 65972]]

No. 28 at p. 10; Whirlpool, No. 26 at p. 1)
    In consideration of this support and for the reasons previously 
stated, DOE incorporates by reference ANSI/AHAM DH-1-2008 in appendix 
X1 as the test method for determining capacity and EF. DOE also does 
not include in appendix X1 the previous reference to the ENERGY STAR 
qualification criteria for determining EF.

J. Removal of Obsolete Measures of Gas Pilot Light Energy Consumption 
in the Conventional Cooking Products Test Procedure and of Energy 
Factor Calculations for Dishwashers

    The energy conservation standards for cooking products require that 
gas cooking products manufactured on or after April 9, 2012, shall not 
be equipped with a constant-burning pilot light. 10 CFR 430.32(j). In 
the May 2012 SNOPR, DOE proposed removing the provisions for measuring 
the energy consumption of constant-burning pilot lights from the 
conventional cooking products test procedures. 77 FR 31444, 31455 (May 
25, 2012).
    AHAM, BSH, and Whirlpool support removing the constant-burning 
pilot light provisions from the conventional cooking products test 
procedures. (AHAM, No. 27 at p. 13; BSH, No. 28 at p. 11; Whirlpool, 
No. 26 at pp. 1, 5) Given this support and the obsolescence of 
constant-burning pilot lights, today's amendments remove the standing 
pilot light provisions from the test procedures for conventional 
cooking products. Specifically, today's final rule removes the 
following existing sections in 10 CFR part 430, subpart B, appendix I:
     Section 2.9.2.2 (``Flow meter'');
     Section 3.1.1.2 (``Continuously burning pilot lights of a 
conventional gas oven'');
     Section 3.1.2.1 (``Continuously burning pilot lights of a 
conventional gas cooking top'');
     Section 3.2.1.3 (``Gas consumption of continuously burning 
pilot lights'' [for conventional gas ovens]);
     Section 3.2.2.1 (``Gas consumption of continuously burning 
pilot lights'' [for conventional gas cooking tops]);
     Section 3.3.7 (recording the gas flow rate or gas 
consumption and elapsed time for a continuously burning pilot light of 
a conventional gas oven);
     Section 3.3.10 (recording the gas flow rate or gas 
consumption and elapsed time for a continuously burning pilot light of 
a conventional gas cooking top);
     Section 4.1.2.2 (``Annual energy consumption of any 
continuously burning pilot lights'' [for conventional gas ovens]); and
     Section 4.2.2.2.2 (``Annual energy consumption of any 
continuously burning gas pilots'' [for conventional gas cooking tops]).
    Today's final rule also modifies (and renumbers where appropriate) 
the following existing sections in appendix I to eliminate the measures 
of energy use relating to gas pilot lights:
     Section 1.7 (``Normal nonoperating temperature'');
     Section 1.14 (``Symbol usage'');
     Section 2.9.2.1 (``Positive displacement meters'');
     Section 3.1.1 (``Conventional oven'');
     Section 3.1.1.1 (``Self-cleaning operation of a 
conventional oven'');
     Section 3.1.2 (``Conventional cooking top'');
     Section 4.1.2.5.2 (``Conventional gas oven energy 
consumption'');
     Section 4.1.2.6.2 (``Conventional gas oven energy 
consumption'' [for multiple conventional gas ovens'']);
     Section 4.2.1.2 (``Gas surface unit cooking efficiency''); 
and
     Section 4.2.2.2.3 (``Total annual energy consumption of a 
conventional gas cooking top'').
    In the May 2012 SNOPR, DOE also proposed to eliminate the 
calculation of energy factor for dishwashers in 10 CFR 430.23 because 
this metric is no longer used in DOE's energy conservation standards 
for dishwashers or to make representations of energy efficiency. 77 FR 
31444, 31455 (May 25, 2012). DOE did not receive any comments on this 
proposal, and amends 10 CFR 430.23 in today's final rule to eliminate 
the energy factor calculation.

K. Compliance With Other EPCA Requirements

1. Test Burden
    EPCA requires that any test procedures prescribed or amended under 
this section be reasonably designed to produce test results which 
measure energy efficiency, energy use or estimated annual operating 
cost of a covered product during a representative average use cycle or 
period of use and shall not be unduly burdensome to conduct. (42 U.S.C. 
6293(b)(3))
    In the December 2010 NOPR, DOE noted that the proposed amendments 
to the residential dishwasher, dehumidifier, and conventional cooking 
products test procedures would incorporate a test standard that is 
accepted internationally for measuring power consumption in standby 
mode and off mode (IEC Standard 62301). DOE analyzed the available 
versions of IEC Standard 62301 at that time--IEC Standard 62301 (First 
Edition), IEC Standard 62301 (CDV), and IEC Standard 62301 (FDIS)--and 
determined that the proposed amendments to the residential dishwashers, 
dehumidifiers, and conventional cooking products test procedures would 
produce standby mode and off mode average power consumption 
measurements representative of an average use cycle. DOE also 
determined that the test methods and equipment that the amendments 
would require for measuring standby mode and off mode power in these 
products would not be substantially different from the test methods and 
equipment required in the current DOE tests. Thus, DOE tentatively 
concluded that the proposed test procedure amendments would not require 
manufacturers to make significant investments in test facilities and 
new equipment. In sum, DOE tentatively concluded in the December 2010 
NOPR that the amended test procedures would produce test results that 
measure the standby mode and off mode power consumption during 
representative use, and that the test procedures would not be unduly 
burdensome to conduct. 75 FR 75290, 75316 (Dec. 2, 2010).
    The September 2011 SNOPR proposed amendments to the DOE test 
procedures based on an updated version of IEC Standard 62301, IEC 
Standard 62301 (Second Edition), which has been the subject of 
significant review and input from interested parties and, thus, 
continues to be an internationally accepted test standard for measuring 
standby mode and off mode power consumption. As discussed in the 
September 2011 SNOPR, the provisions of IEC Standard 62301 (Second 
Edition) that DOE proposed to incorporate by reference provide a means 
to measure power consumption with greater accuracy and repeatability 
than the provisions from IEC Standard 62301 (First Edition) that were 
originally proposed in the December 2010 NOPR. For this reason, DOE 
tentatively concluded that the amendments proposed in the September 
2011 SNOPR would also provide measurements representative of average 
consumer use of the product under test. DOE further determined that 
these new provisions in the applicable sections of IEC Standard 62301 
(Second Edition) would improve test results without undue testing 
burden. DOE acknowledged in the September 2011 SNOPR that certain 
methods from IEC Standard 62301 (Second Edition) may increase test 
duration, but where such an increase was deemed excessive (i.e., for 
products

[[Page 65973]]

with clocks that can vary in power consumption as a function of time 
displayed), DOE retained the method previously proposed to mitigate 
test burden. The potential for increased test burden in other power 
consumption measurements is offset by more reasonable requirements for 
testing equipment, while maintaining measurement accuracy deemed 
acceptable and practical by voting members for IEC Standard 62301 
(Second Edition). Thus, DOE tentatively concluded that the amended test 
procedures proposed in the September 2011 SNOPR would produce test 
results that measure the standby mode and off mode power consumption 
during representative use, and that the test procedures would not be 
unduly burdensome to conduct. 76 FR 58346, 58354 (Sep. 20, 2011).
    In the May 2012 SNOPR, DOE proposed to measure energy use in fan-
only mode for dishwashers and conventional cooking products as a 
continuation of the active mode cycle, which would require more 
stringent specifications for the watt-hour meters than currently 
specified in the dishwasher and conventional cooking products test 
procedures. By not requiring a separate cycle to be run, the proposed 
approach would minimize test burden associated with the measurement of 
fan-only mode. The May 2012 SNOPR also proposed amendments to 
incorporate the energy and water use associated with dishwasher water 
softener regeneration. Manufacturers would need to run up to an 
additional ten cycles to ensure that a regeneration process is 
captured. DOE based this proposal on the information supplied by 
manufacturers that, on average, water-softening dishwashers regenerate 
approximately once every six cycles. To minimize test burden, 
particularly for soil-sensing dishwashers, DOE proposed in the May 2012 
SNOPR that these cycles would be run with no test load, since DOE 
believes that a substantial part of the burden for the existing test 
procedure is incurred by the preparation and application of soils to 
the dishware. 77 FR 31444, 31447-51 (May 25, 2012).
    The May 2012 SNOPR's proposal to reference AHAM DH-1-2008 in the 
dehumidifier test procedure would, according to DOE's estimates, 
require more accurate measurement equipment that would cost 
approximately $500. DOE also noted in the May 2012 SNOPR that the 
proposed test room requirements could require the use of a larger test 
chamber than is specified under the current test procedure, and could 
also require different air handling equipment. DOE noted that many test 
laboratories may already be using AHAM DH-1-2008 and, thus, may already 
meet these requirements. In addition, for those laboratories that are 
recording data manually, the more frequent data recording events in 
DOE's proposal could result in three times the data recording events 
than are currently required. Because only four parameters are recorded 
for each event, however, DOE estimated in the May 2012 SNOPR that the 
total increase in operator time would be less than 1 hour. 77 FR 31444, 
31453-54 (May 25, 2012).
    In the August 2012 SNOPR, DOE noted that the replacement items 
proposed were intended to be inexpensive, representative of commonly-
found items, and in some cases already used by manufacturers in testing 
dishwashers. In addition, DOE proposed a definition of normal cycle for 
dishwashers supported by manufacturers because it will lead to 
consistent, representative results. The updated industry test method 
for dishwashers was also supported by manufactures because it will lead 
to, among other things, reduced test variation, as would the proposals 
for consistent preparation time for the soils used in the test 
procedure, the positioning of the dishwasher rack during testing, the 
method of loading, the tighter tolerances on ambient temperature, the 
added specifications for water pressure measurement and drain height, 
and the clarifications for the rinse aid container. Finally, DOE 
proposed an alternative method of measuring the energy use in fan-only 
mode for dishwashers and cooking products that could significantly 
decrease overall testing time. 77 FR 49064, 49065-67 (Aug. 15, 2012).
    AHAM, BSH, and Whirlpool estimated the test burden associated with 
the proposed water softener regeneration test method for the dishwasher 
test procedure to be 20 to 30 additional test hours. (AHAM, No. 27 at 
p. 4; BSH, No. 28 at p. 2; Whirlpool, No. 26 at p. 1) DOE considered 
manufacturer test burden when it evaluated comments on its proposed 
methodology for measuring energy and water use due to water softener 
regeneration, and acknowledges that the proposal would add burden by 
requiring up to an additional 10 dishwasher washing and drying cycles, 
compared to either one or three washing and drying cycles and one 
preconditioning cycle currently required in the test procedure. As 
discussed in section III.F.3, DOE is not adopting the proposed testing 
methodology in today's final rule due to this burden, Instead, DOE 
includes in the new dishwasher test procedure measures of energy and 
water consumption for water softener regeneration using manufacturer-
reported values for the energy and water use for each regeneration 
cycle and the number of annual regeneration cycles.
    DOE additionally discusses in section IV.B of this notice comments 
received regarding the investments that manufacturers may incur due to 
today's final rule and DOE's determination that they do not represent 
significant burden. Therefore, for the reasons discussed above, DOE 
concludes that the new and amended test procedures for dishwashers, 
dehumidifiers, and conventional cooking products will produce test 
results that measure the active mode, standby mode, and off mode power 
consumption during representative use, and that the test procedures 
will not be unduly burdensome to conduct.
2. Certification Requirements
    As codified at 42 U.S.C. 6299, et seq., EPCA authorizes DOE to 
enforce compliance with the energy and water conservation standards 
established for covered consumer products. On March 7, 2011, the 
Department published a final rule in the Federal Register, which 
revised, consolidated, and streamlined its existing certification, 
compliance, and enforcement regulations for covered consumer products, 
including dishwashers, dehumidifiers, and conventional cooking 
products. 76 FR 12422.\18\ The certification regulations are codified 
at 10 CFR 429.19 (dishwashers), 10 CFR 429.23 (conventional cooking 
tops, conventional ovens, microwave ovens), and 10 CFR 429.36 
(dehumidifiers).
---------------------------------------------------------------------------

    \18\ Certification requirements for industrial equipment are 
also included in these regulations.
---------------------------------------------------------------------------

    The certification requirements for each of the products covered in 
today's final rule consist of a sampling plan for selection of units 
for testing and requirements for certification reports. AHAM commented 
that no revisions would be required for current standards for 
dehumidifiers and conventional cooking products, so that no changes are 
necessary for the reporting requirements for these products. AHAM also 
supported DOE's proposed changes to the sampling plan for dehumidifiers 
and conventional cooking products. (AHAM, No. 20 at p. 3) Because the 
amendments and new provisions adopted for dehumidifiers and 
conventional cooking products test procedures will not revise the 
current energy conservation standards, DOE is not proposing any 
amendments to the certification

[[Page 65974]]

reporting requirements for these products. However, because DOE in 
today's final rule introduces a new metric (IEF) for both conventional 
cooking products and dehumidifiers, DOE additionally amends provisions 
in the sampling plan at 10 CFR 429.23 and 10 CFR 429.36 that include 
IEF along with the existing measure of EF.
    AHAM stated that the measured energy use for dishwashers will be 
affected by the amendments to the dishwasher test procedure. For 
example, cycle finished mode energy use is not currently measured, but 
will required to be included under the amended test procedure. AHAM 
commented that DOE should amend the reporting requirements to account 
for the change. (AHAM, No. 20 at p. 3) No such amendments are adopted 
for residential dishwashers in today's final rule because DOE is not 
adding any new energy efficiency metric for these products. DOE is, 
though, amending in today's final rule the reporting requirements in 10 
CFR 429.19 for dishwashers to specify that manufacturers submit with 
their certification reports: (1) The cycle selected for the energy 
test; (2) whether the cycle selected for the energy test is soil-
sensing; (3) the options selected for the energy test; and (4) whether 
the dishwasher has a built-in water softening system, and if yes, the 
energy and water use required for each regeneration of the water 
softening system, the number of regeneration cycles per year, and data 
and calculations used to derive these values.

IV. Procedural Issues and Regulatory Review

A. Review Under Executive Order 12866

    The Office of Management and Budget has determined that test 
procedure rulemakings do not constitute ``significant regulatory 
actions'' under section 3(f) of Executive Order 12866, Regulatory 
Planning and Review, 58 FR 51735 (Oct. 4, 1993). Accordingly, this 
action was not subject to review under the Executive Order by the 
Office of Information and Regulatory Affairs (OIRA) in the Office of 
Management and Budget (OMB).

B. Review Under the Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
preparation of a regulatory flexibility analysis for any rule that by 
law must be proposed for public comment, unless the agency certifies 
that the rule, if promulgated, will not have a significant economic 
impact on a substantial number of small entities. As required by 
Executive Order 13272, ``Proper Consideration of Small Entities in 
Agency Rulemaking,'' 67 FR 53461 (Aug. 16, 2002), DOE published 
procedures and policies on February 19, 2003, to ensure that the 
potential impacts of its rules on small entities are properly 
considered during the DOE rulemaking process. 68 FR 7990. DOE has made 
its procedures and policies available on the Office of the General 
Counsel's Web site: www.gc.doe.gov/gc/office-general-counsel
    DOE reviewed today's final rule under the provisions of the 
Regulatory Flexibility Act and the procedures and policies published on 
February 19, 2003. DOE has concluded that the rule would not have a 
significant impact on a substantial number of small entities. The 
factual basis for this certification is as follows:
    The Small Business Administration (SBA) considers a business entity 
to be small business, if, together with its affiliates, it employs less 
than a threshold number of workers specified in 13 CFR part 121. These 
size standards and codes are established by the North American Industry 
Classification System (NAICS). The threshold number for NAICS 
classification code 335228, ``Other Major Household Appliance 
Manufacturing,'' which applies to residential dishwasher manufacturers, 
is 500 employees. The threshold number for NAICS classification code 
335221, ``Household Cooking Appliance Manufacturing,'' which applies to 
manufacturers of residential conventional cooking products, is 750 
employees. The threshold number for NAICS classification code 335211, 
``Electric Housewares and Household Fan Manufacturing,'' which applies 
to dehumidifier manufacturers, is 750 employees.
    Most of the manufacturers supplying residential dishwashers, 
dehumidifiers, and/or conventional cooking products are large 
multinational corporations. DOE surveyed the AHAM member directory to 
identify manufacturers of residential dishwashers, dehumidifiers and 
conventional cooking products. DOE then consulted publicly-available 
data, purchased company reports from vendors such as Dun and 
Bradstreet, and contacted manufacturers, where needed, to determine if 
they meet the SBA's definition of a ``small business manufacturing 
facility'' and have their manufacturing facilities located within the 
United States. Based on this analysis, DOE identified no small 
businesses that manufacture dishwashers, five small businesses that 
manufacture dehumidifiers, and two small businesses that manufacture 
conventional cooking products.
    Today's final rule amends DOE's test procedures for dishwashers, 
dehumidifiers, and cooking products. Because DOE is unaware of any 
small businesses that manufacture dishwashers, there are no impacts on 
such manufacturers due to the amendments to DOE's dishwasher test 
procedure.
    Today's rule amends DOE's test procedures for dehumidifiers and 
conventional cooking products by incorporating testing provisions to 
address standby mode and off mode energy use in these products, as well 
as cooking products fan-only mode energy consumption. The test 
procedure amendments involve measuring power input when the product is 
in standby mode or off mode, as well as fan-only mode for a 
conventional cooking product. These tests can be conducted in the same 
facilities used for the current energy testing of these products, so 
there are no additional facilities costs required by this final rule. 
In addition, while the watt-hour meter required for these tests might 
require greater accuracy than the watt-hour meter used for current 
energy testing, the investment required for a possible instrumentation 
upgrade would likely be relatively modest. It is possible that the 
manufacturers, or their testing facilities, already have equipment that 
meets the more stringent meter requirements, but an Internet search of 
equipment that specifically meets the requirements reveals a cost of 
approximately $2,000.
    Whirlpool stated that the equipment necessary to meet the 
requirements of IEC Standard 62301 (Second Edition) for measuring 
airflow and harmonics either does not exist or does not exist in 
sufficient accuracy or quantity. Whirlpool estimated that the cost to 
its company of such equipment would be up to $48,000, and that the cost 
for test equipment upgrades for the harmonics measurement alone would 
be $10,000. (Whirlpool, No.21 at p. 3; Whirlpool, No. 26 at p. 6) 
Although Whirlpool's estimates are higher than DOE's, DOE recognizes 
that a large manufacturer may require multiple meters to equip its 
testing facilities, and that a small business would likely require 
investments in the range of DOE's estimates.
    Today's final rule also updates the industry test method for 
dehumidifiers in new appendix X1. As discussed in III.K.1, this update 
could impose on manufacturers a cost for new measurement equipment of 
approximately $500, as well as

[[Page 65975]]

potentially increasing operator time by less than 1 hour over the 
course of a 24-hour test.
    The costs described above are small compared to the overall 
financial investment needed to undertake the business enterprise of 
testing consumer products which involves facilities, qualified staff, 
and specialized equipment. Based on its review of industry data,\19\ 
DOE estimates that the small dehumidifier and cooking product 
businesses have annual revenues of $10 million to $60 million.
---------------------------------------------------------------------------

    \19\ Annual revenue estimates based on financial reports 
obtained from Hoover's Inc., available online at www.hoovers.com.
---------------------------------------------------------------------------

    DOE recognizes that the updated reference to the industry 
dehumidifier test method could potentially require manufacturers to 
install a larger test chamber and different air handling equipment. 
However, some manufacturers may already be using ANSI/AHAM DH-1-2008 in 
certifying their products. DOE notes that one of the small businesses 
has products listed in AHAM's current dehumidifier certification 
database, indicating that those tests were conducted according to DH-1-
2008. In addition, AHAM selected an independent test laboratory to 
conduct dehumidifier testing and verification using DH-1-2008. It is 
likely that testing that this laboratory performs for manufacturers to 
determine compliance with energy conservation standards would be 
conducted in the same facility. Therefore, DOE concludes that small 
businesses would not be likely to require investments in facility 
upgrades due to the new dehumidifier test procedure that references DH-
1-2008.
    Furthermore, DOE adopts in today's final rule amendments that limit 
the duration of the fan-only mode testing for conventional ovens and 
conventional ranges to minimize test burden. Under today's final rule, 
the energy use in fan-only mode is measured for 10 minutes, and then 
extrapolated over the duration of the fan-mode. DOE estimates that the 
total time currently required for conventional oven testing (or for 
testing the conventional oven portion of a range) to be approximately 4 
hours for products not equipped with the capability for forced 
convection or self-cleaning, with an additional 3 hours required for 
testing forced convection and an additional 4 hours required for 
testing self-clean operation. DOE's research did not identify any 
conventional ovens or conventional ranges manufactured by either of the 
two small cooking products manufacturers that are equipped with either 
forced convection or self-clean capability. DOE estimates that fan-only 
mode testing in the absence of such features could increase testing 
time by approximately 3 percent. However, DOE's research also suggests 
that none of the conventional ovens and conventional ranges 
manufactured by the two small cooking products businesses are capable 
of operation in fan-only mode, and therefore it is unlikely that these 
manufacturers would be impacted by the fan-only mode testing 
provisions.
    For these reasons, DOE concludes and certifies that today's final 
rule will not have a significant economic impact on a substantial 
number of small entities. Accordingly, DOE has not prepared a 
regulatory flexibility analysis for this rulemaking. DOE has 
transmitted the certification and supporting statement of factual basis 
to the Chief Counsel for Advocacy of the SBA for review under 5 U.S.C. 
605(b).

C. Review Under the Paperwork Reduction Act of 1995

    Manufacturers of residential dishwashers, dehumidifiers, and 
conventional cooking products must certify to DOE that their products 
comply with any applicable energy conservation standards. In certifying 
compliance, manufacturers must test their products according to the DOE 
test procedures for residential dishwashers, dehumidifiers, and 
conventional cooking products including any amendments adopted for 
those test procedures. DOE has established regulations for the 
certification and recordkeeping requirements for all covered consumer 
products and commercial equipment, including residential dishwashers, 
dehumidifiers, and conventional cooking products. (76 FR 12422 (Mar. 7, 
2011). The collection-of-information requirement for the certification 
and recordkeeping is subject to review and approval by OMB under the 
Paperwork Reduction Act (PRA). This requirement has been approved by 
OMB under OMB control number 1910-1400. Public reporting burden for the 
certification is estimated to average 20 hours per response, including 
the time for reviewing instructions, searching existing data sources, 
gathering and maintaining the data needed, and completing and reviewing 
the collection of information.
    Notwithstanding any other provision of the law, no person is 
required to respond to, nor shall any person be subject to a penalty 
for failure to comply with, a collection of information subject to the 
requirements of the PRA, unless that collection of information displays 
a currently valid OMB Control Number.

D. Review Under the National Environmental Policy Act of 1969

    In this final rule, DOE amends its test procedure for residential 
dishwashers, dehumidifiers, and conventional cooking products. DOE has 
determined that this rule falls into a class of actions that are 
categorically excluded from review under the National Environmental 
Policy Act of 1969 (42 U.S.C. 4321 et seq.) and DOE's implementing 
regulations at 10 CFR part 1021. Specifically, this rule amends an 
existing rule without affecting the amount, quality or distribution of 
energy usage, and, therefore, will not result in any environmental 
impacts. Thus, this rulemaking is covered by Categorical Exclusion A5 
under 10 CFR part 1021, subpart D, which applies to any rulemaking that 
interprets or amends an existing rule without changing the 
environmental effect of that rule. Accordingly, neither an 
environmental assessment nor an environmental impact statement is 
required.

E. Review Under Executive Order 13132

    Executive Order 13132, ``Federalism,'' 64 FR 43255 (Aug. 4, 1999) 
imposes certain requirements on agencies formulating and implementing 
policies or regulations that preempt State law or that have Federalism 
implications. The Executive Order requires agencies to examine the 
constitutional and statutory authority supporting any action that would 
limit the policymaking discretion of the States and to carefully assess 
the necessity for such actions. The Executive Order also requires 
agencies to have an accountable process to ensure meaningful and timely 
input by State and local officials in the development of regulatory 
policies that have Federalism implications. On March 14, 2000, DOE 
published a statement of policy describing the intergovernmental 
consultation process it will follow in the development of such 
regulations. 65 FR 13735. DOE examined this final rule and determined 
that it will not have a substantial direct effect on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government. EPCA governs and prescribes Federal preemption of State 
regulations as to energy conservation for the products that are the 
subject of today's final rule. States can petition DOE for exemption 
from such preemption to the extent, and based on criteria, set forth in 
EPCA. (42

[[Page 65976]]

U.S.C. 6297(d)) No further action is required by Executive Order 13132.

F. Review Under Executive Order 12988

    Regarding the review of existing regulations and the promulgation 
of new regulations, section 3(a) of Executive Order 12988, ``Civil 
Justice Reform,'' 61 FR 4729 (Feb. 7, 1996), imposes on Federal 
agencies the general duty to adhere to the following requirements: (1) 
Eliminate drafting errors and ambiguity; (2) write regulations to 
minimize litigation; (3) provide a clear legal standard for affected 
conduct rather than a general standard; and (4) promote simplification 
and burden reduction. Section 3(b) of Executive Order 12988 
specifically requires that Executive agencies make every reasonable 
effort to ensure that the regulation: (1) Clearly specifies the 
preemptive effect, if any; (2) clearly specifies any effect on existing 
Federal law or regulation; (3) provides a clear legal standard for 
affected conduct while promoting simplification and burden reduction; 
(4) specifies the retroactive effect, if any; (5) adequately defines 
key terms; and (6) addresses other important issues affecting clarity 
and general draftsmanship under any guidelines issued by the Attorney 
General. Section 3(c) of Executive Order 12988 requires Executive 
agencies to review regulations in light of applicable standards in 
sections 3(a) and 3(b) to determine whether they are met or it is 
unreasonable to meet one or more of them. DOE has completed the 
required review and determined that, to the extent permitted by law, 
this final rule meets the relevant standards of Executive Order 12988.

G. Review Under the Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) 
requires each Federal agency to assess the effects of Federal 
regulatory actions on State, local, and Tribal governments and the 
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531). 
For a regulatory action resulting in a rule that may cause the 
expenditure by State, local, and Tribal governments, in the aggregate, 
or by the private sector of $100 million or more in any one year 
(adjusted annually for inflation), section 202 of UMRA requires a 
Federal agency to publish a written statement that estimates the 
resulting costs, benefits, and other effects on the national economy. 
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to 
develop an effective process to permit timely input by elected officers 
of State, local, and Tribal governments on a proposed ``significant 
intergovernmental mandate,'' and requires an agency plan for giving 
notice and opportunity for timely input to potentially affected small 
governments before establishing any requirements that might 
significantly or uniquely affect small governments. On March 18, 1997, 
DOE published a statement of policy on its process for 
intergovernmental consultation under UMRA. 62 FR 12820; also available 
at www.gc.doe.gov. DOE examined today's final rule according to UMRA 
and its statement of policy and determined that the rule contains 
neither an intergovernmental mandate, nor a mandate that may result in 
the expenditure of $100 million or more in any year, so these 
requirements do not apply.

H. Review Under the Treasury and General Government Appropriations Act, 
1999

    Section 654 of the Treasury and General Government Appropriations 
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family 
Policymaking Assessment for any rule that may affect family well-being. 
Today's final rule will not have any impact on the autonomy or 
integrity of the family as an institution. Accordingly, DOE has 
concluded that it is not necessary to prepare a Family Policymaking 
Assessment.

I. Review Under Executive Order 12630

    DOE has determined, under Executive Order 12630, ``Governmental 
Actions and Interference with Constitutionally Protected Property 
Rights'' 53 FR 8859 (Mar.18, 1988), that this regulation will not 
result in any takings that might require compensation under the Fifth 
Amendment to the U.S. Constitution.

J. Review Under Treasury and General Government Appropriations Act, 
2001

    Section 515 of the Treasury and General Government Appropriations 
Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most 
disseminations of information to the public under guidelines 
established by each agency pursuant to general guidelines issued by 
OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 2002), and 
DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has 
reviewed today's final rule under the OMB and DOE guidelines and has 
concluded that it is consistent with applicable policies in those 
guidelines.

K. Review Under Executive Order 13211

    Executive Order 13211, ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use,'' 66 FR 28355 
(May 22, 2001), requires Federal agencies to prepare and submit to OMB, 
a Statement of Energy Effects for any significant energy action. A 
``significant energy action'' is defined as any action by an agency 
that promulgated or is expected to lead to promulgation of a final 
rule, and that: (1) Is a significant regulatory action under Executive 
Order 12866, or any successor order; and (2) is likely to have a 
significant adverse effect on the supply, distribution, or use of 
energy; or (3) is designated by the Administrator of OIRA as a 
significant energy action. For any significant energy action, the 
agency must give a detailed statement of any adverse effects on energy 
supply, distribution, or use if the regulation is implemented, and of 
reasonable alternatives to the action and their expected benefits on 
energy supply, distribution, and use.
    Today's regulatory action is not a significant regulatory action 
under Executive Order 12866. Moreover, it would not have a significant 
adverse effect on the supply, distribution, or use of energy, nor has 
it been designated as a significant energy action by the Administrator 
of OIRA. Therefore, it is not a significant energy action, and, 
accordingly, DOE has not prepared a Statement of Energy Effects.

L. Review Under Section 32 of the Federal Energy Administration Act of 
1974

    Under section 301 of the Department of Energy Organization Act 
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the 
Federal Energy Administration Act of 1974, as amended by the Federal 
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA) 
Section 32 essentially provides in relevant part that, where a proposed 
rule authorizes or requires use of commercial standards, the notice of 
proposed rulemaking must inform the public of the use and background of 
such standards. In addition, section 32(c) requires DOE to consult with 
the Attorney General and the Chairman of the Federal Trade Commission 
(FTC) concerning the impact of the commercial or industry standards on 
competition.
    The amendments to the test procedures in today's final rule 
incorporate testing methods contained in certain sections of the 
following commercial standards:
    1. ANSI/AHAM Standard DH-1-2008, Dehumidifiers, 2008, ANSI approved 
May 9, 2008.

[[Page 65977]]

    2. ANSI/AHAM Standard DW-1-2010, Household Electric Dishwashers, 
ANSI approved September 10, 2010.
    3. IEC Standard 62301, Household electrical appliances--Measurement 
of standby power, Edition 2.0, 2011-01.
    DOE has evaluated these standards and is unable to conclude whether 
they fully comply with the requirements of section 32(b) of the FEAA 
(i.e., whether they were developed in a manner that fully provides for 
public participation, comment, and review.) DOE has consulted with both 
the Attorney General and the Chairman of the FTC about the impact on 
competition of using the methods contained in these standards and has 
received no comments objecting to their use.

M. Congressional Notification

    As required by 5 U.S.C. 801, DOE will report to Congress on the 
promulgation of today's rule before its effective date. The report will 
state that it has been determined that the rule is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).

V. Approval of the Office of the Secretary

    The Secretary of Energy has approved publication of this final 
rule.

4. Test Cycle and Measurements

    4.1 Active mode cycle. Perform a test cycle by establishing the 
testing conditions set forth in section 2 of this appendix, setting 
the dishwasher to the cycle type to be tested according to section 
2.6.1, 2.6.2, or 2.6.3 of this appendix, initiating the cycle, and 
allowing the cycle to proceed to completion.
    4.1.1 Machine electrical energy consumption. Measure the machine 
electrical energy consumption, M, expressed as the number of 
kilowatt-hours of electricity consumed by the machine during the 
entire test cycle, using a water supply temperature as set forth in 
section 2.3 of this appendix and using a watt-hour meter as 
specified in section 3.5 of this appendix.
    4.1.2 Fan electrical energy consumption. If the dishwasher is 
capable of operation in fan-only mode, measure the fan electrical 
energy consumption, MF, expressed as the number of 
kilowatt-hours of electricity consumed by the machine for the 
duration of fan-only mode, using a watt-hour meter as specified in 
section 3.5 of this appendix. Alternatively, if the duration of fan-
only mode is known, the watt-hours consumed may be measured for a 
period of 10 minutes in fan-only mode, using a watt-hour meter as 
specified in section 3.5 of this appendix. Multiply this value by 
the time in minutes that the dishwasher remains in fan-only mode, 
LF, and divide by 10,000 to obtain MF. The 
alternative approach may be used only if the resulting MF 
is representative of energy use during the entire fan-only mode.
    4.1.3 Water consumption. Measure the water consumption, V, 
expressed as the number of gallons of water delivered to the machine 
during the entire test cycle, using a water meter specified in 
section 3.3 of this appendix.
    4.2 Standby mode and off mode power. Connect the dishwasher to a 
standby mode and off mode watt meter as specified in section 3.6 of 
this appendix. Establish the testing conditions set forth in 
sections 2.1, 2.2, and 2.5.2 of this appendix. For dishwashers that 
take some time to enter a stable state from a higher power state as 
discussed in Section 5, Paragraph 5.1, note 1 of IEC 62301 
(incorporated by reference; see Sec.  430.3), allow sufficient time 
for the dishwasher to reach the lower power state before proceeding 
with the test measurement. Follow the test procedure specified in 
Section 5, Paragraph 5.3.2 of IEC 62301 for testing in each possible 
mode as described in sections 4.2.1 and 4.2.2 of this appendix.

section 1.10 of this appendix, measure and record the average 
inactive mode power of the dishwasher, PIA, in watts.
    4.2.2 If the dishwasher has an off mode, as defined in section 
1.13 of this appendix, measure and record the average off mode 
power, POM, in watts.

5. Calculation of Derived Results From Test Measurements

    5.1 Machine energy consumption.
    5.1.1 Machine energy consumption for non-soil-sensing electric 
dishwashers. Take the value recorded in section 4.1.1 of this 
appendix as the per-cycle machine electrical energy consumption. 
Express the value, M, in kilowatt-hours per cycle.
    5.1.2 Machine energy consumption for soil-sensing electric 
dishwashers. The machine energy consumption for the sensor normal 
cycle, M, is defined as:

M = (Mhr x Fhr) + (Mmr x 
Fmr) + (Mlr x Flr)

where,

Mhr = the value recorded in section 4.1.1 of this 
appendix for the test of the sensor heavy response, expressed in 
kilowatt-hours per cycle,
Mmr = the value recorded in section 4.1.1 of this 
appendix for the test of the sensor medium response, expressed in 
kilowatt-hours per cycle,
Mlr = the value recorded in section 4.1.1 of this 
appendix for the test of the sensor light response, expressed in 
kilowatt-hours per cycle,
Fhr = the weighting factor based on consumer use of heavy 
response = 0.05,
Fmr = the weighting factor based on consumer use of 
medium response = 0.33, and
Flr = the weighting factor based on consumer use of light 
response = 0.62.

    5.1.3 Machine energy consumption during water softener 
regeneration for water-softening dishwashers. The machine energy 
consumption for water softener regeneration, MWS, is 
defined as:

MWS = MWScycle x NWS/N

where,

Appendix I to Subpart B of Part 430--Uniform Test Method for Measuring 
the Energy Consumption of Conventional Ranges, Conventional Cooking 
Tops, Conventional Ovens, and Microwave Ovens

    Note: The procedures and calculations in this Appendix I need 
not be performed to determine compliance with energy conservation 
standards for conventional ranges, conventional cooking tops, 
conventional ovens, and microwave ovens at this time. However, any 
representation made after April 29, 2013 related to standby mode and 
off mode energy consumption of conventional ranges, conventional 
cooking tops, and conventional ovens, and any representation made 
after September 6, 2011 related to standby mode and off mode energy 
consumption of microwave ovens, must be based upon results generated 
under this test procedure, consistent with the requirements of 42 
U.S.C. 6293(c)(2). Upon the compliance date of any energy 
conservation standard that incorporates standby mode and off mode 
energy consumption, compliance with the applicable provisions of 
this test procedure will also be required. Future revisions may add 
relevant provisions for measuring active mode in microwave ovens.

1. Definitions

    1.1 Active mode means a mode in which the product is connected 
to a mains power source, has been activated, and is performing the 
main functions of producing heat by means of a gas flame, electric 
resistance heating, or microwave energy, or circulating air 
internally or externally to the cooking product. Delay start mode is 
a one-off, user-initiated, short-duration function that is 
associated with an active mode.
    1.2 Built-in means the product is supported by surrounding 
cabinetry, walls, or other similar structures.
    1.3 Combined low-power mode means the aggregate of available 
modes other than active mode, but including the delay start mode 
portion of active mode.
    1.4 Cycle finished mode means a standby mode in which a 
conventional cooking top,

[[Page 65988]]

conventional oven, or conventional range provides continuous status 
display following operation in active mode.
    1.5 Drop-in means the product is supported by horizontal surface 
cabinetry.
    1.6 Fan-only mode means an active mode that is not user-
selectable and in which a fan circulates air internally or 
externally to the cooking product for a finite period of time after 
the end of the heating function, where the end of the heating 
function is indicated to the consumer by means of a display, 
indicator light, or audible signal.
    1.7 Forced convection means a mode of conventional oven 
operation in which a fan is used to circulate the heated air within 
the oven compartment during cooking.
    1.8 Freestanding means the product is not supported by 
surrounding cabinetry, walls, or other similar structures.
    1.9 IEC 62301 (First Edition) means the test standard published 
by the International Electrotechnical Commission, titled ``Household 
electrical appliances--Measurement of standby power,'' Publication 
62301 (First Edition 2005-06) (incorporated by reference; see Sec.  
430.3).
    1.10 IEC 62301 (Second Edition) means the test standard 
published by the International Electrotechnical Commission, titled 
``Household electrical appliances--Measurement of standby power,'' 
Publication 62301 (Edition 2.0 2011-01) (incorporated by reference; 
see Sec.  430.3).
    1.11 Inactive mode means a standby mode that facilitates the 
activation of active mode by remote switch (including remote 
control), internal sensor, or timer, or that provides continuous 
status display.
    1.12 Normal non-operating temperature means the temperature of 
all areas of an appliance to be tested are within 5 [deg]F (2.8 
[deg]C) of the temperature that the identical areas of the same 
basic model of the appliance would attain if it remained in the test 
room for 24 hours while not operating with all oven doors closed.
    1.13 Off mode means a mode in which the product is connected to 
a mains power source and is not providing any active mode or standby 
mode function, and where the mode may persist for an indefinite 
time. An indicator that only shows the user that the product is in 
the off position is included within the classification of an off 
mode.
    1.14 Primary energy consumption means either the electrical 
energy consumption of a conventional electric oven or the gas energy 
consumption of a conventional gas oven.
    1.15 Secondary energy consumption means any electrical energy 
consumption of a conventional gas oven.
    1.16 Standard cubic foot (L) of gas means that quantity of gas 
that occupies 1 cubic foot (L) when saturated with water vapor at a 
temperature of 60[emsp14][deg]F (15.6 [deg]C) and a pressure of 30 
inches of mercury (101.6 kPa) (density of mercury equals 13.595 
grams per cubic centimeter).
    1.17 Standby mode means any modes where the product is connected 
to a mains power source and offers one or more of the following 
user-oriented or protective functions which may persist for an 
indefinite time: (a) To facilitate the activation of other modes 
(including activation or deactivation of active mode) by remote 
switch (including remote control), internal sensor, or timer; (b) 
continuous functions, including information or status displays 
(including clocks) or sensor-based functions. A timer is a 
continuous clock function (which may or may not be associated with a 
display) that provides regular scheduled tasks (e.g., switching) and 
that operates on a continuous basis.
    1.18 Thermocouple means a device consisting of two dissimilar 
metals which are joined together and, with their associated wires, 
are used to measure temperature by means of electromotive force.

3. Test Methods and Measurements

* * * * *
    3.1.1 Conventional oven. Perform a test by establishing the 
testing conditions set forth in section 2, Test Conditions, of this 
appendix and turn off the gas flow to the conventional cooking top, 
if so equipped. Before beginning the test, the conventional oven 
shall be at its normal non-operating temperature as defined in 
section 1.12 and described in section 2.6 of this appendix. Set the 
conventional oven test block W1 approximately in the 
center of the usable baking space. If there is a selector switch for 
selecting the mode of operation of the oven, set it for normal 
baking. If an oven permits baking by either forced convection by 
using a fan, or without forced convection, the oven is to be tested 
in each of those two modes. The oven shall remain on for one 
complete thermostat ``cut-off/cut-on'' of the electrical resistance 
heaters or gas burners after the test block temperature has 
increased 234[emsp14][deg]F (130 [deg]C) above its initial 
temperature.
    3.1.1.1 Self-cleaning operation of a conventional oven. 
Establish the test conditions set forth in section 2, Test 
Conditions, of this appendix. Turn off the gas flow to the 
conventional cooking top. The temperature of the conventional oven 
shall be its normal non-operating temperature as defined in section 
1.12 and described in section 2.6 of this appendix. Then set the 
conventional oven's self-cleaning process in accordance with the 
manufacturer's instructions. If the self-cleaning process is 
adjustable, use the average time recommended by the manufacturer for 
a moderately soiled oven.
    3.1.1.2 Conventional oven standby mode and off mode power. 
Establish the standby mode and off mode testing conditions set forth 
in section 2, Test Conditions, of this appendix. For conventional 
ovens that take some time to enter a stable state from a higher 
power state as discussed in Section 5, Paragraph 5.1, Note 1 of IEC 
62301 (Second Edition) (incorporated by reference; see Sec.  430.3), 
allow sufficient time for the conventional oven to reach the lower 
power state before proceeding with the test measurement. Follow the 
test procedure as specified in Section 5, Paragraph 5.3.2 of IEC 
62301 (Second Edition) for testing in each possible mode as 
described in 3.1.1.2.1 and 3.1.1.2.2 of this appendix. For units in 
which power varies as a function of displayed time in standby mode, 
set the clock time to 3:23 at the end of the stabilization period 
specified in Section 5, Paragraph 5.3 of IEC 62301 (First Edition), 
and use the average power approach described in Section 5, Paragraph 
5.3.2(a) of IEC 62301 (First Edition), but with a single test period 
of 10 minutes +0/-2 sec after an additional stabilization period 
until the clock time reaches 3:33.

temperature of the conventional cooking top shall be its normal 
nonoperating temperature as defined in section 1.12 and described in 
section 2.6 of this appendix. Set the test block in the center of 
the surface unit under test. The small test block, W2, 
shall be used on electric surface units of 7 inches (178 mm) or less 
in diameter. The large test block, W3, shall be used on 
electric surface units over 7 inches (178 mm) in diameter and on all 
gas surface units. Turn on the surface unit under test and set its 
energy input rate to the maximum setting. When the test block 
reaches 144[emsp14][deg]F (80 [deg]C) above its initial test block 
temperature, immediately reduce the energy input rate to 255 percent of the maximum energy input rate. After 150.1 minutes at the reduced energy setting, turn off the 
surface unit under test.

operation in either standby mode or off mode, as defined in sections 
1.17 or 1.13 of this appendix, respectively, or both, test the 
microwave oven in each mode in which it can operate.
* * * * *
    3.2.1 Conventional oven test energy consumption. If the oven 
thermostat controls the oven temperature without cycling on and off, 
measure the energy consumed, EO, when the temperature of 
the block reaches TO (TO is 234[emsp14][deg]F 
(130 [deg]C) above the initial block temperature, TI). If 
the oven thermostat operates by cycling on and off, make the 
following series of measurements: Measure the block temperature, 
TA, and the energy consumed, EA, or volume of 
gas consumed, VA, at the end of the last ``ON'' period of 
the conventional oven before the block reaches TO. 
Measure the block temperature, TB, and the energy 
consumed, EB, or volume of gas consumed, VB, 
at the beginning of the next ``ON'' period. Measure the block 
temperature, TC, and the energy consumed, EC, 
or volume of gas consumed, VC, at the end of that ``ON'' 
period. Measure the block temperature, TD, and the energy 
consumed, ED, or volume of gas consumed, VD, 
at the beginning of the following ``ON'' period. Energy measurements 
for EO, EA, EB, EC, and 
ED should be expressed in watt-hours (kJ) for 
conventional electric ovens, and volume measurements for 
VA, VB, VC, and VD 
should be expressed in standard cubic feet (L) of gas for 
conventional gas ovens. For a gas oven, measure in watt-hours (kJ) 
any electrical energy, EIO, consumed by an ignition 
device or other electrical components required for the operation of 
a conventional gas oven while heating the test block to 
TO.
    3.2.1.1 Conventional oven average test energy consumption. If 
the conventional oven permits baking by either forced convection or 
without forced convection and the oven thermostat does not cycle on 
and off, measure the energy consumed with the forced convection 
mode, (EO)1, and without the forced convection 
mode, (EO)2, when the temperature of the block 
reaches TO (TO is 234 [deg]F (130 [deg]C) 
above the initial block temperature, TI). If the 
conventional oven permits baking by either forced convection or 
without forced convection and the oven thermostat operates by 
cycling on and off, make the following series of measurements with 
and without the forced convection mode: Measure the block 
temperature, TA, and the energy consumed, EA, 
or volume of gas consumed, VA, at the end of the last 
``ON'' period of the conventional oven before the block reaches 
TO. Measure the block temperature, TB, and the

EC, and ED should be expressed in watt-hours 
(kJ) for conventional electric ovens, and volume measurements for 
VA, VB, VC, and VD 
should be expressed in standard cubic feet (L) of gas for 
conventional gas ovens. For a gas oven that can be operated with or 
without forced convection, measure in watt-hours (kJ) any electrical 
energy consumed by an ignition device or other electrical components 
required for the operation of a conventional gas oven while heating 
the test block to TO using the forced convection mode, 
(EIO)1, and without using the forced 
convection mode, (EIO)2.

expressed in kilowatt-hours (kJ) of electricity consumed by the 
conventional oven for the duration of fan-only mode, using a watt-
hour meter as specified in section 2.9.1.1 of this appendix. 
Alternatively, if the duration of fan-only mode is known, the watt-
hours consumed may be measured for a period of 10 minutes in fan-
only mode, using a watt-hour meter as specified in section 2.9.1.1 
of this appendix. Multiply this value by the time in minutes that 
the conventional oven remains in fan-only mode, tOF, and

may be used only if the resulting EOF is representative 
of energy use during the entire fan-only mode.
    3.2.1.3 Energy consumption of self-cleaning operation. Measure 
the energy consumption, ES, in watt-hours (kJ) of 
electricity or the volume of gas consumption, VS, in 
standard cubic feet (L) during the self-cleaning test set forth in 
section 3.1.1.1 of this appendix. For a gas oven, also measure in 
watt-hours (kJ) any electrical energy, EIS, consumed by 
ignition devices or other electrical components required during the 
self-cleaning test.

the test specified in section 3.1.2 of this appendix and the total 
time, tCT, in hours, that the unit is under test. Measure 
any electrical energy, EIC, consumed by an ignition 
device of a gas heating element or other electrical components 
required for the operation of the conventional gas cooking top in 
watt-hours (kJ).

appendix. If the conventional range is capable of operating in off 
mode, as defined in section 1.13 of this appendix, measure the

1. Scope

    This appendix covers the test requirements used to measure the 
energy performance of dehumidifiers.

2. Definitions

    2.1 ANSI/AHAM DH-1 means the test standard published by the 
American National Standards Institute and the Association of Home 
Appliance Manufacturers, titled ``Dehumidifiers,'' ANSI/AHAM DH-1-
2008, (incorporated by reference; see Sec.  430.3).
    2.2 Active mode means a mode in which a dehumidifier is 
connected to a mains power source, has been activated, and is 
performing the main functions of removing moisture from air by 
drawing moist air over a refrigerated coil using a fan, or 
circulating air through activation of the fan without activation of 
the refrigeration system.
    2.3 Combined low-power mode means the aggregate of available 
modes other than active mode.
    2.4 Energy factor for dehumidifiers means a measure of energy 
efficiency of a dehumidifier calculated by dividing the water 
removed from the air by the energy consumed, measured in liters per 
kilowatt-hour (L/kWh).
    2.5 IEC 62301 means the test standard published by the 
International Electrotechnical Commission, titled ``Household 
electrical appliances--Measurement of standby power,'' Publication 
62301 (Edition 2.0 2011-01) (incorporated by reference; see Sec.  
430.3).
    2.6 Inactive mode means a standby mode that facilitates the 
activation of active mode by remote switch (including remote 
control), internal sensor, or timer, or that provides continuous 
status display.
    2.7 Off mode means a mode in which the dehumidifier is connected 
to a mains power source and is not providing any active mode or 
standby mode function, and where the mode may persist for an 
indefinite time. An indicator that only shows the user that the 
dehumidifier is in the off position is included within the 
classification of an off mode.
    2.8 Off-cycle mode means a standby mode in which the 
dehumidifier:
    (1) Has cycled off its main function by humidistat or humidity 
sensor;
    (2) Does not have its fan or blower operating; and
    (3) Will reactivate the main function according to the 
humidistat or humidity sensor signal.
    2.9 Product capacity for dehumidifiers means a measure of the 
ability of the dehumidifier to remove moisture from its surrounding 
atmosphere, measured in pints collected per 24 hours of continuous 
operation.
    2.10 Standby mode means any modes where the dehumidifier is 
connected to a mains power source and offers one or more of the 
following user-oriented or protective functions which may persist 
for an indefinite time:
    (1) To facilitate the activation of other modes (including 
activation or deactivation of active mode) by remote switch 
(including remote control), internal sensor, or timer;
    (2) Continuous functions, including information or status 
displays (including clocks) or sensor-based functions. A timer is a 
continuous clock function (which may or may not be associated with a 
display) that provides regular scheduled tasks (e.g., switching) and 
that operates on a continuous basis.

3. Test Apparatus and General Instructions

    3.1 Active mode. The test apparatus and instructions for testing 
dehumidifiers shall conform to the requirements specified in Section 
3, ``Definitions,'' Section 4, ``Instrumentation,'' and Section 5, 
``Test Procedure,'' of ANSI/AHAM DH-1 (incorporated by reference, 
see Sec.  430.3). Record measurements at the resolution of the test 
instrumentation. Round off calculations to the same number of 
significant digits as the previous step. Round the final minimum 
energy factor value to two decimal places as follows:
    (i) A fractional number at or above the midpoint between two 
consecutive decimal places shall be rounded up to the higher of the 
two decimal places; or
    (ii) A fractional number below the midpoint between two 
consecutive decimal places shall be rounded down to the lower of the 
two decimal places.
    3.2 Standby mode and off mode.
    3.2.1 Installation requirements. For the standby mode and off 
mode testing, the dehumidifier shall be installed in accordance with 
Section 5, Paragraph 5.2 of IEC 62301 (incorporated by reference, 
see Sec.  430.3), disregarding the provisions regarding batteries 
and the determination, classification, and testing of relevant 
modes.
    3.2.2 Electrical energy supply.

testing, maintain the electrical supply voltage and frequency 
indicated in Section 7.1.3, ``Standard Test Voltage,'' of ANSI/AHAM 
DH-1, (incorporated by reference, see Sec.  430.3). The electrical 
supply frequency shall be maintained 1 percent.
    3.2.2.2 Supply voltage waveform. For the standby mode and off 
mode testing, maintain the electrical supply voltage waveform 
indicated in Section 4, Paragraph 4.3.2 of IEC 62301, (incorporated 
by reference; see Sec.  430.3).
    3.2.3 Standby mode and off mode watt meter. The watt meter used 
to measure standby mode and off mode power consumption shall meet 
the requirements specified in Section 4, Paragraph 4.4 of IEC 62301 
(incorporated by reference, see Sec.  430.3).
    3.2.4 Standby mode and off mode ambient temperature. For standby 
mode and off mode testing, maintain room ambient air temperature 
conditions as specified in Section 4, Paragraph 4.2 of IEC 62301 
(incorporated by reference; see Sec.  430.3).

4. Test Measurement

expressed in liters per kilowatt hour (L/kWh) and product capacity 
in pints per day (pints/day), in accordance with the test 
requirements specified in Section 7, ``Capacity Test and Energy 
Consumption Test,'' of ANSI/AHAM DH-1 (incorporated by reference, 
see Sec.  430.3).
    4.2 Standby mode and off mode. Establish the testing conditions 
set forth in section 3.2 of this appendix, ensuring that the 
dehumidifier does not enter active mode during the test. For 
dehumidifiers that take some time to enter a stable state from a 
higher power state as discussed in Section 5, Paragraph 5.1, Note 1 
of IEC 62301, (incorporated by reference; see Sec.  430.3), allow 
sufficient time for the dehumidifier to reach the lower power state 
before proceeding with the test measurement. Follow the test 
procedure specified in Section 5, Paragraph 5.3.2 of IEC 62301 for 
testing in each possible mode as described in sections 4.2.1 and 
4.2.2 of this appendix.
    4.2.1 If the dehumidifier has an inactive mode, as defined in 
section 2.6 of this appendix, but not an off mode, as defined in 
section 2.7 of this appendix, measure and record the average 
inactive mode power of the dehumidifier, PIA, in watts. 
Otherwise, if the dehumidifier has an off mode, as defined in 
section 2.7 of this appendix, measure and record the average off 
mode power of the dehumidifier, POM, in watts.

ETLP = [(PIO x SIO) + 
(POC x SOC)] x K

Where:

PIO = PIA, dehumidifier inactive mode power, 
or POM, dehumidifier off mode power, in watts, as 
measured in section 4.2.1 of this appendix.
POC = dehumidifier off-cycle mode power, in watts, as 
measured in section 4.2.2 of this appendix.
SIO = 1840,5 dehumidifier inactive mode or off mode 
annual hours.
SOC = 1840,5 dehumidifier off-cycle mode annual hours.

K = 0.001 kWh/Wh conversion factor for watt-hours to kilowatt-hours.

    5.2 Integrated energy factor. Calculate the integrated energy 
factor, IEF, expressed in liters per kilowatt-hour, rounded to two 
decimal places, according to the following:

IEF = LW/(Eactive + ((ETLP x 24)/
Sactive))

Where:

LW = water removed from the air during dehumidifier 
energy factor test, in liters, as measured in section 4.1 of this 
appendix.
Eactive = dehumidifier energy factor test energy 
consumption, in kilowatt-hours, as measured in section 4.1 of this 
appendix.
ETLP = standby mode and off mode annual energy 
consumption, in kilowatt-hours per year, as calculated in section 
5.1 of this appendix.
24 = hours per day.
Sactive = 1,095, dehumidifier active mode annual hours.
