RIN 1904-AC01


Energy Conservation Program: Test Procedures for Residential 
Dishwashers, Dehumidifiers, and Conventional Cooking Products (Standby 
Mode and Off Mode)

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

ACTION: Supplemental notice of proposed rulemaking (SNOPR).

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

SUMMARY: The U.S. Department of Energy (DOE) proposes to amend its test 
procedures for residential dishwashers, dehumidifiers, and conventional 
cooking products (which includes cooktops, ovens, and ranges) to 
address the measurement of active mode fan-only energy use. This SNOPR 
also addresses energy and water use associated with dishwasher water 
softeners, the energy test cycle for dishwashers with a separate soil-
sensing cycle, and the normal cycle definition, power supply and 
detergent dosing for dishwashers. The proposal would also update the 
industry test method specified in the dehumidifier test procedure, 
eliminate measurement of gas pilot light energy use in the cooking 
products test procedure, and remove an obsolete energy efficiency 
metric in the dishwasher test procedure.

I. Authority and Background

    Title III, Part B \1\ of the Energy Policy and Conservation Act of 
1975 (EPCA or the Act), Public Law 94-163 (42 U.S.C. 6291-6309, as 
codified) sets forth a variety of provisions designed to improve energy 
efficiency and established the Energy Conservation Program for Consumer 
Products Other Than Automobiles, a program covering most major 
household appliances.\2\ These include residential dishwashers, 
conventional cooking products,\3\ and dehumidifiers, the subject of 
today's notice. (42 U.S.C. 6292(a)(6) and (10); 6295(cc))
---------------------------------------------------------------------------

    \1\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated Part A.
    \2\ All references to EPCA in this rulemaking refer to the 
statute as amended through the Energy Independence and Security Act 
of 2007, Public Law 110-140.
    \3\ 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 the Act, this program consists essentially of four parts: (1) 
Testing, (2) labeling, (3) establishing Federal energy conservation 
standards, and (4) certification and enforcement procedures. The 
testing requirements consist of test procedures that manufacturers of 
covered products must use: (1) as the basis for certifying to DOE that 
their products comply with applicable energy conservation standards 
adopted pursuant to EPCA, and (2) for making representations about the 
efficiency of those products. (42 U.S.C. 6293(c); 6295(s)) Similarly, 
DOE must use these test procedures in any enforcement action to 
determine whether the products comply with these energy conservation 
standards. (42 U.S.C. 6295(s))

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 in relevant part 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, as 
determined by DOE, 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))
    EPCA, in relevant part, require 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.''\4\ Id.
---------------------------------------------------------------------------

    \4\ EISA 2007 directs DOE to also consider IEC Standard 62087 
when amending its test procedures to include standby mode and off 
mode energy consumption. See 42 U.S.C. 6295(gg)(2)(A). IEC Standard 
62087 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.
---------------------------------------------------------------------------

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 (August 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 [deg]F inlet water. 48 FR 9202 (March 
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 
[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 (August 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 U.S. Environmental 
Protection Agency's (EPA) test criteria used under the ENERGY STAR \5\ 
program must serve as the basis for the test procedure for 
dehumidifiers. (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. Conventional Cooking Products
    DOE's test procedures for conventional ranges, cooktops, and ovens 
(including microwave ovens) are

[[Page 31446]]

found at 10 CFR part 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 
part 430 subpart B, appendix I. There is currently no EnergyGuide \6\ 
labeling program for cooking products.
---------------------------------------------------------------------------

    \6\ For more information on the EnergyGuide labeling program, 
see: www.access.gpo.gov/nara/cfr/waisidx_00/16cfr305_00.html.
---------------------------------------------------------------------------

    In today's SNOPR, DOE proposes amendments to its cooking products 
test procedure for only conventional cooking products. DOE has 
initiated a separate test procedure rulemaking to address standby mode 
and off mode power consumption for microwave ovens. The microwaves 
rulemaking was initiated in response to comments from interested 
parties on the advance notice of proposed rulemaking (ANOPR) for an 
earlier rulemaking concerning energy conservation standards for 
residential dishwashers, dehumidifiers, cooking products, and 
commercial clothes washers published on November 15, 2007 (hereafter 
referred to as the November 2007 ANOPR) (72 FR 64432). As discussed in 
the subsequent notice of proposed rulemaking (NOPR) for that standards 
rulemaking, interested parties stated generally that DOE should amend 
the test procedures for all types of cooking products to allow for 
measurement of standby mode energy use in order to implement a standby 
power energy conservation standard. 73 FR 62034, 62043-44 (Oct. 17, 
2008). DOE published a NOPR proposing amendments to the microwave oven 
test procedure for standby mode and off mode in the Federal Register on 
October 17, 2008. 73 FR 62134. DOE subsequently published a 
supplemental notice of proposed rulemaking (SNOPR) in the Federal 
Register on this topic on July 22, 2010 (75 FR 42612), and an interim 
final rule on March 9, 2011 (hereafter referred to as the March 2011 
Interim Final Rule) (76 FR 12825). DOE sought comment on a newly issued 
version of IEC Standard 62301 (which is discussed in more detail in the 
following section) for measuring standby mode and off mode energy use, 
the previous version of which was incorporated by reference in the 
microwave oven test procedure. In response to comments received on the 
interim final rule, DOE proposed to incorporate by reference the newly 
issued version of IEC Standard 62301 in an SNOPR published in the 
Federal Register on November 23, 2011. 76 FR 72332.

B. Standby Mode and Off Mode

    EPCA requires DOE to amend the test procedures for covered products 
to address standby mode and off mode energy consumption. Specifically, 
the amendments require DOE to integrate standby mode and off mode 
energy consumption into the overall energy efficiency, energy 
consumption, or other energy descriptor for that product unless the 
current test procedures already fully account for such consumption. If 
integration is technically infeasible, DOE must prescribe a separate 
standby mode and off mode energy use test procedure, 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.'' Id.

C. The December 2010 NOPR

    On December 2, 2010, DOE published a NOPR (hereafter called 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.\7\ Id. at 75300-04. DOE held a public meeting on 
December 17, 2010, 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.
---------------------------------------------------------------------------

    \7\ 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.
---------------------------------------------------------------------------

D. The September 2011 SNOPR

    Based upon the public comment received on the December 2010 NOPR, 
DOE further analyzed the draft materials associated with IEC Standard 
62301 (Second Edition), which were in an advanced stage of development. 
Shortly thereafter, 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. Consistent with its statutory mandate, 
DOE reviewed this latest version of the IEC standard and agreed 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 called 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 newly 
proposed in the September 2011 SNOPR, DOE continued to propose the test 
procedure amendments originally included in the December 2010 NOPR.

[[Page 31447]]

II. Summary of the Supplemental Notice of Proposed Rulemaking

    Upon further review of the public comment received on its 
proposals, DOE decided to further analyze the energy use of an air-
circulating fan during a portion of cycle finished mode for dishwashers 
and conventional cooking products. DOE's analysis suggests that 
measurement of the energy use during this ``fan-only'' mode (considered 
part of the active mode) could improve the measurement of dishwasher 
and conventional cooking product energy use. Accordingly, DOE proposes 
in today's SNOPR to amend the DOE test procedures for residential 
dishwashers and conventional cooking products to incorporate the 
measurement of energy use in fan-only mode in the energy efficiency 
metrics.
    DOE also proposes amendments to the dishwasher test procedure to 
measure the annual energy and water use associated with periodic water 
softener system regeneration for those dishwashers equipped with such 
systems. DOE's proposal in today's SNOPR considers: (1) the data on 
this subject accompanying petitions for waiver from the dishwasher test 
procedure for water-softening dishwashers, submitted by manufacturers; 
the methodology for addressing water softener system regeneration that 
was provided in waivers that were subsequently granted to 
manufacturers; and additional research and analysis that DOE conducted 
for today's SNOPR.
    DOE also proposes in today's SNOPR to clarify in the dishwasher 
test procedure: (1) The normal cycle definition; (2) power supply 
requirements during testing; (3) energy test cycle requirements for 
dishwashers with a separate soil-sensing cycle; (4) test load 
specifications and soiling requirements; and (5) detergent dosing 
specifications.
    The proposal would also update the industry test method specified 
in the dehumidifier test procedure. As noted above, EPCA specifies that 
the EPA's test criteria used under the ENERGY STAR program must serve 
as the basis for the test procedure for dehumidifiers. (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. Because the version of the DH-1 standard was not 
specified in the ENERGY STAR test criteria, DOE proposes to incorporate 
the most current version of the DH-1 standard (2008) into the test 
procedure for dehumidifiers.
    Today's proposal would also eliminate measures of pilot light 
energy consumption from the cooking products 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. DOE also proposes in today's SNOPR 
to remove the calculation of an obsolete energy efficiency metric, EF, 
from the dishwasher test procedure because the current dishwasher 
energy conservation standards no longer require it for compliance or 
representations.
    Other than the specific amendments newly proposed in today's SNOPR, 
DOE continues to propose the test procedure amendments originally 
included in the December 2010 NOPR and the September 2011 SNOPR. For 
the reader's convenience, DOE has reproduced in this SNOPR the entire 
body of proposed regulatory text from the December 2010 NOPR and 
September 2011 SNOPR, further amended as appropriate according to 
today's proposals. DOE's supporting analysis and discussion for the 
portions of the proposed regulatory text not affected by this SNOPR may 
be found in the December 2010 NOPR (75 FR 75290 (Dec. 2, 2010)) and the 
September 2011 SNOPR (76 FR 58346 (Sept. 20, 2011)).

III. Discussion

A. Fan-Only Mode

    In the December 2010 NOPR, DOE proposed to include the measurement 
of energy use in ``cycle finished'' mode for dishwashers and 
conventional cooking products, defined as ``a mode that provides 
continuous status display following operation in active mode.'' 75 FR 
75290, 75298-99 (Dec. 2, 2010). DOE maintained this proposed definition 
in the September 2011 SNOPR. 76 FR 58346 (Sept. 20, 2011).
    DOE received comments on the December 2010 NOPR and September 2011 
SNOPR which noted that certain components in addition to a continuous 
status display could be energized for at least a portion of cycle 
finished mode in these products. Appliance Standards Awareness Project 
(ASAP) asked whether DOE had identified other energy-consuming sources 
not covered in by the definition of cycle finished mode, such as fans 
used in conventional ovens. Southern California Edison (SCE), Southern 
California Gas Company (SCG), and San Diego Gas and Electric Company 
(SDG&E), jointly (hereafter referred to as ``California Utilities''); 
ASAP, American Council for Energy Efficient Economy (ACEEE), National 
Consumer Law Center (NCLC), and Natural Resources Defense Council 
(NRDC), jointly (hereafter referred to as the ``NOPR Joint Comment''); 
and Pacific Gas and Electric (PG&E) commented that some models of 
dishwashers and conventional cooking products currently on the market 
contain fans or other components that continue to run after the active 
cycles are finished and that may consume significantly more power than 
a continuous display. ASAP, ACEEE, and NCLC, jointly (hereafter 
referred to as the ``SNOPR Joint Comment''), ASAP individually, the 
California Utilities, the NOPR Joint Comment, and PG&E stated that DOE 
should expand the definition of cycle finished mode for dishwashers and 
conventional cooking products to include any energy-consuming features 
following operation in active mode. (ASAP, Public Meeting Transcript, 
No. 10 at pp. 60-61; \8\ California Utilities, No. 16 at p. 2; NOPR 
Joint Comment, No. 13 at pp. 1-2; PG&E, No. 17 at p. 2 \9\; SNOPR Joint 
Comment, No. 22 at p. 1) Northwest Energy Efficiency Alliance (NEEA) 
stated that many electronically controlled conventional cooking 
products have a fan-powered cooling function built into the active 
cooking mode (to protect the electronic controls from excessive 
heating) that persists beyond the functions listed in DOE's proposed 
definition of active mode. According to NEEA, because the period in 
which the fan operates occurs after the active mode functions end, and 
the duration of fan operation depends on the temperature at which the 
main cooking function(s) were conducted, fan-only mode would not meet 
DOE's proposed definition of inactive (standby) mode. NEEA commented 
that the inactive mode for a cooking product

[[Page 31448]]

begins after the cooling fan stops, and therefore the cooling function 
is part of active mode. For dishwashers, NEEA requested clarification 
as to whether such functions as a fan operating during the drying cycle 
are part of the active washing and drying cycle, or are part of cycle 
finished mode. NEEA commented that this cooling function in dishwashers 
should be considered as part of active mode. (NEEA, No. 11 at pp. 2-4) 
The NOPR Joint Comment stated that DOE should measure the duration of 
cycle finished mode in the absence of user interaction and estimate 
typical consumer use. According to the NOPR Joint Comment, the current 
proposal of 1.1 hours per cycle may be low, given that several 
dishwashers have cooling fans that continue to run for several hours 
following completion of the active cycle. The NOPR Joint Comment also 
noted that certain ovens and ranges include a cooling fan that can run 
up to 2 hours after the end of the active cycle. The NOPR Joint Comment 
suggested, therefore, that cycle finished mode likely continues on 
average for much longer than the proposed 5 minutes. The NOPR Joint 
Comment expressed concern about DOE's use of the use of European data 
for estimating the duration of cycle finished mode, and suggested that 
DOE make its own measurements or obtain data from manufacturers. (NOPR 
Joint Comment, No. 13 at pp. 4-5)

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

    In considering these comments, DOE researched the functions, 
average power consumption, and duration of operation of air circulation 
fans in both dishwashers and conventional cooking products at the 
completion of the active cycle. The following sections discuss the 
results of these analyses separately for the two product types.
1. Dishwashers
    Certain dishwashers incorporate an air circulation fan to transfer 
moisture from the dishware and out of the unit through an open vent 
more effectively than natural convection through the vent, The air 
circulation fan may remain energized for a period after the drying 
portion of an active cycle is complete, during which time the 
continuous status display indicates to the consumer that the cycle has 
finished. DOE research suggests that such fans typically require 
approximately 12 to 20 watts (W) of additional input power, and run 10 
minutes to 4 hours after completion of the active cycle, depending on 
the type of drying cycle setting selected by the user. Based on this 
information, DOE calculated the range of annual energy consumption 
associated with an air circulation fan operating after the end of the 
active cycle as (12 to 20 W) x (10 minutes to 4 hours) x (215 estimated 
number of dishwashing cycles according to the DOE test procedure) = 0.4 
to 17 kWh. The higher end of the range is greater than 5 percent of the 
maximum allowable annual energy consumption for a standard dishwasher 
(355 kWh). DOE proposes to measure the energy consumption associated 
with an air circulation fan operating at the end of the active cycle as 
described in section III.C.
    In the December 2010 NOPR, DOE proposed to define ``standby mode'' 
as any mode 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; or (b) continuous functions, including information or 
status displays (including clocks) or sensor-based functions. As noted 
previously, cycle finished mode was proposed in the December 2010 NOPR 
as a mode that provides continuous status display following operation 
in active mode, which would classify cycle finished mode as a standby 
mode. 75 FR 75290, 75298-99 (Dec. 2, 2010). DOE maintained these 
proposed definitions in the September 2011 SNOPR. 76 FR 58346, 58349-50 
(Sept. 20, 2011). DOE recognizes that the operation of an air 
circulation fan for a limited duration following the active cycle would 
preclude such a ``fan-only'' mode from consideration as cycle finished 
mode and, more generally, a standby mode under the proposed 
definitions. Therefore, DOE considers fan-only mode to be an active 
mode uniquely associated with the active cycle. DOE proposes in today's 
SNOPR to define fan-only mode as ``an active mode in which a fan 
circulates air for a finite period of time after the end of the cycle, 
as indicated to the consumer.''
2. Conventional Cooking Products
    Conventional ovens operate at cavity temperatures typically greater 
than 300 degrees Fahrenheit ([deg]F) during an active cooking cycle. To 
maintain safe temperatures of the surrounding surfaces during the 
active cycle and to cool internal oven components after completion of 
the cycle, conventional ovens and ranges often incorporate an air 
circulation fan. DOE research indicates that the air circulation fan 
may be activated at the end of the active cooking cycle based on some 
combination of the oven cavity internal temperature and cooking 
function (e.g., ``bake'', ``broil''), or may be programmed to run for a 
fixed time. For conventional ovens and ranges which operate the air 
circulation fan according to the oven cavity temperature, DOE observed 
in the sample that it reviewed that the threshold temperature at which 
the fan would be activated ranged from 100[deg]F to 360[deg]F. For 
those conventional ovens and ranges with time-controlled fan operation, 
the duration of the ``fan-only'' mode in the sample that DOE identified 
ranged from 10 minutes to 3.5 hours after completion of the active mode 
cycle. DOE found no conventional cooktops with air circulation fans.
    DOE research suggests that the air circulation fans in conventional 
ovens and ranges typically require approximately 16 to 50 W of input 
power. To estimate the number of annual cooking cycles for each 
conventional oven and range, DOE reviewed available consumer usage 
data. DOE's Energy Information Agency (EIA) conducts a Residential 
Energy Consumption Survey (RECS) that collects energy-related data for 
occupied primary housing units in the United States. The 2009 RECS 
collected data from 12,083 housing units representing over 113 million 
households.\10\ The RECS indicates which households in the survey use 
electric and gas ranges and ovens. With regard to electric cooking 
products, 2332 household records have standard ovens and 5258 household 
records have self-cleaning ovens. With regard to gas cooking products, 
2075 household records have standard ovens, and 2315 household records 
have self-cleaning ovens. The above totals represent ovens in 
households as either a stand-alone unit or as part of a range. Table 
III.1 presents the weighted-average cooking frequency values of each 
product class. DOE calculated the range of annual energy consumption 
associated with an air circulation fan operating after the end of the 
active cooking cycle as (16 to 50 W) x (10 minutes to 3.5 hours) x 
(weighted average cooking frequency per day) x (365 days per year). 
Table III.1 also shows this range of calculated annual energy 
consumption associated with air circulation fans for each product 
class, along with the annual energy consumption in other active modes 
of a baseline product.\11\ The higher end of

[[Page 31449]]

the range for each class is greater than 11 percent of the baseline 
annual energy use. DOE proposes to measure the energy consumption 
associated with an air circulation fan operating at the end of the 
active cycle as described in section III.C.

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

    As with dishwashers, DOE also tentatively concludes that operation 
of the fan after the end of the active cycle, i.e., in fan-only mode, 
would classify this mode as part of active mode rather than cycle 
finished mode or, more generally, standby mode. DOE proposes for 
conventional cooking products to define fan-only mode as ``an active 
mode 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, as indicated to the consumer.''

B. Dishwasher Water Softener Regeneration

    The current dishwasher test procedure does not account specifically 
for the regeneration operation of the water softener in its measurement 
of energy and water use. Manufacturers have filed petitions for waiver 
from the test procedure applicable to dishwashers for units that 
contain a built-in water softener regeneration system, asserting that: 
(1) The amount of water consumed by the regeneration operation of a 
water softener in a dishwasher is very small, but varies significantly 
depending on the adjustment of the softener; (2) the regeneration 
operation takes place infrequently and is related to the level of water 
hardness; and (3) including this water use in the measurement of water 
consumption during an individual energy test cycle could overstate 
water and energy use.
    These manufacturers estimated through in-house measurements that 
the water softener regeneration occurs once every six active mode 
cycles, and that the system consumes approximately 23 gallons of water 
and 4 kWh of electricity per year, assuming an average U.S. water 
hardness of 217 milligrams per liter (mg/L). One manufacturer also 
estimated that the system consumes 4.97 L of water per regeneration 
cycle, and that approximately 50 percent of U.S. households that have 
hard water have their entire water supply softened. The manufacturers 
requested approval to measure the water consumption of dishwashers 
having water softeners without including the water consumed by the 
dishwasher during softener regeneration, as outlined in European 
Standard EN 50242, ``Electric Dishwashers for Household Use--Methods 
for Measuring the Performance.''
    DOE granted waivers to these manufacturers that provided an 
alternate means to account for the water and energy used during water 
softener regeneration. The waivers permitted these manufacturers to 
measure water and energy consumption of the specified dishwasher models 
that have water softener regeneration systems according to the 
following methodology:
    (a) The DOE test is initiated on a cycle immediately following a 
regeneration cycle.
    (b) Water and energy consumption shall be measured according to the 
DOE test procedure in 10 CFR part 430, subpart B, appendix C, ensuring 
that regeneration does not take place during the test.
    (c) Constant values of 23 gallons/year of water and 4 kWh/year of 
energy, representing the water and energy consumption associated with 
water softener regeneration, shall be added to the estimated annual 
energy and water use.
    (d) Should regeneration happen during the DOE test, the water 
consumed during water softener regeneration can be disregarded for the 
per cycle water and energy consumption measurement, provided constant 
values are added to the estimated annual energy and water use. The 
constant values in the waivers were specified as 23 gallons/year of 
water and 4 kWh/year of energy and 47.6 gallons/year of water and 8 
kWh/year of energy, respectively. (DOE did not find evidence that 50 
percent of U.S. households with hard water have their entire water 
supply softened.)
    (e) Representations about the energy use of water-softening 
dishwashers that are the subject of such waivers for compliance, 
marketing, or other purposes may be made only to the extent that such 
products have been testing according to this methodology.
    In response to the December 2010 NOPR and September 2011 SNOPR, DOE 
received comments regarding the measurement of energy and water use for 
dishwasher water softener regeneration. BSH Home Appliances Corporation 
(BSH) and Earthjustice noted the waiver granted to Whirlpool 
Corporation (Whirlpool), and BSH suggested that DOE consider for this 
rulemaking the same approach of adding the incremental energy use 
associated with the regeneration process. Earthjustice requested that 
DOE inform the public of its plans to amend the dishwasher test 
procedure accordingly. (BSH, Public Meeting Transcript, No. 10 at p. 
37; Earthjustice, No. 15 at p. 1) BSH commented that recent 
interpretations have considered water softener regeneration to be part 
of active mode, and that DOE treats it differently than the IEC does. 
According to BSH, the IEC does not consider regeneration as active 
mode, but as a secondary process separate from washing the dishware. 
BSH further commented that there are limited data in the United States 
regarding how many dishwashers have the regeneration function, and how 
often this function is activated. BSH stated

[[Page 31450]]

that water softening systems are typically on very high-end products, 
and that it believes that homes in which these dishwashers are 
installed typically have home water softening systems, so that the 
frequency of use could be very low. (BSH, Public Meeting Transcript, 
No. 10 at pp. 37-39).
    In response to these comments, DOE conducted analysis for today's 
SNOPR in support of potential dishwasher test procedure amendments to 
address water softener regeneration.
    Based on review of the data submitted by manufacturers in their 
petitions for waiver, product database research, and manufacturer 
interviews, DOE observed that some areas in the United States have hard 
municipal or locally supplied water, defined as having calcium ion 
concentrations higher than 180 parts per million (ppm). Hard water 
prevents soaps and detergents from properly sudsing, resulting in 
unsatisfactory cleaning performance. To address this issue, some 
residential dishwashers have a built-in water softening system to 
minimize excess use of detergent and re-cleaning of the dishware due to 
unsatisfactory washing. The water softener system may consist of a 
resin bed which provides an ion exchange to remove calcium and 
magnesium ions from the water, by swapping sodium ions bonded to the 
resin with the calcium and magnesium ions. Over time, the calcium and 
magnesium replace all the sodium in the resin bed, which therefore must 
be periodically recharged with sodium by flushing a saline solution 
over it, a process which is referred to as regeneration. During a cycle 
which includes a regeneration process, additional water is mixed with 
sodium chloride (salt) supplied by the consumer in a compartment 
separate from the detergent compartment to create the saline solution, 
and this incremental water consumption requires energy to heat it to 
the same temperature as is used for the active cycle.
    The frequency of the water softener regeneration is dependent on 
the following:
    (a) Amount of water consumed in a normal cycle;
    (b) Hardness of the water at the inlet to the dishwasher; and
    (c) Hardness level set by the user on the unit as per 
manufacturer's instructions. Typically, the user is asked to determine 
the hardness of the water (in ppm) and to set the level in the 
dishwasher accordingly. If the hardness level in the unit is set to 0, 
the water softening system will not be used and thus a regeneration 
process will take place infrequently or never.
    As noted previously, according to manufacturer data, the average 
water hardness in U.S. households is 217 ppm (12.6 grains per gallon), 
and that at this level, the regeneration process will take place in 
their dishwashers equipped with built-in water softening systems 
approximately once every six active cycles, or 36 times per year. DOE 
does not have additional information regarding whether this frequency 
is representative of other dishwashers with built-in water softening 
systems, the prevalence of home water softening systems, and consumer 
usage habits. Therefore, DOE is proposing to retain the value of 36 
regeneration events per year, but seeks comment and information on a 
representative frequency.
    DOE then examined the electrical and water heating energy 
consumption, along with water consumption, to determine appropriate 
test procedure amendments for representative dishwashers with built-in 
water softening systems. Machine electrical energy consumption 
associated with the regeneration process primarily consists of the 
energy consumed to activate a dedicated solenoid valve to the water 
softening system and additional activation of the drain pump to 
circulate and flush the saline solution, as well as any electrical 
energy needed to heat the water internally. Because the regeneration 
process takes place over approximately 20 seconds, and because the 
electrical power associated with the water handling components is 
estimated by DOE based on its research to be less than 100 W, the 
maximum electrical energy use per regeneration process for the water 
handling components is 0.0005 kWh. Assuming 36 regeneration events 
occur per year, the annual electrical energy use associated with water 
softener regeneration would be only 0.02 kWh, or less than 0.01 percent 
of the maximum allowable annual energy use in active mode and standby 
mode for standard dishwashers. (DOE is not aware of any compact 
dishwashers with built-in water softening systems.) Therefore, the 
primary machine electrical energy use during water softener 
regeneration is associated with internal water heating.
    According to the data submitted by manufacturers in their petitions 
for waiver, the volume of water consumed for a water softener 
regeneration process ranges between 2.4 and 5 L (0.63 to 1.32 gallons) 
per active cycle that includes regeneration. Since regeneration is 
estimated to occur once every six active cycles, this would correspond 
to an average allocation of 0.1 to 0.2 gallons per active cycle for the 
regeneration process. These average water consumption values should be 
adjusted to account for the percentage of homes with hard water that 
use home water softening systems instead of the dishwasher built-in 
system, but DOE lacks data to assign a value to this percentage, and 
for the purposes of today's SNOPR is proposing to assume that all 
dishwashers with built-in water softeners perform the periodic 
regeneration. The current residential dishwasher energy conservation 
standards allow for a maximum water consumption of 6.5 gallons per 
cycle for standard dishwashers, so that water softener water 
consumption would represent at least 2 percent of the allowable water 
consumption. DOE proposes to measure the water consumption associated 
with regeneration for dishwashers with built-in water softening 
systems. DOE requests data and information on this percentage, as well 
as the incremental water consumption associated with built-in water 
softener regeneration.
    Similarly, DOE examined the water-heating energy consumption for 
water softener regeneration, based on the allocation of 0.1 to 0.2 
gallons of additional water consumption per active cycle. The water-
heating energy use was calculated as (0.1 to 0.2 gallons per active 
cycle) x (the nominal temperature rise of 90[emsp14][deg]F from the 
nominal cold water temperature of 50[emsp14][deg]F to the nominal hot 
water temperature in the dishwasher of 140[emsp14][deg]F) x (specific 
heat of water, 0.0024 kWh per gallon per [deg]F) x (1-percentage of 
households with home water softening systems) x (215 active cycles per 
year). This would be calculated as 4.6 to 9.2 kWh per year if all 
households with hard water were assumed to require the use of the 
dishwasher water softening system, which represents at least 1 percent 
of the maximum allowable annual energy use of 355 kWh for standard 
dishwashers. Because the water heating may take place internally in the 
dishwasher or externally in the home water heater, DOE proposes to 
measure the machine electrical energy consumption as well as the water 
consumption associated with water softener regeneration. As discussed 
previously, DOE does not have information regarding the percentage of 
households with hard water that use home water softening systems and is 
therefore proposing in today's SNOPR to assign a value of zero to this 
percentage. DOE seeks comment on this percentage and the inclusion of 
water-heating energy use associated with water softener regeneration in 
the proposed

[[Page 31451]]

amendments to the dishwasher test procedure.

C. Calculation of Energy Consumption in Active, Standby, and Off Modes

    In the December 2010 NOPR, DOE proposed two possible approaches 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.\12\ These modes are collectively 
referred to as low-power modes in this proposal. For the first 
approach, DOE proposed allocating specific annual hours to each of the 
active, standby, and off mode hours. Using this approach, the annual 
energy use associated with inactive, off, delay start, and cycle 
finished modes would be calculated by (1) Calculating the product of 
wattage and allocated hours for all possible inactive, off, delay start 
and cycle finished modes; (2) summing the results; and (3) dividing the 
sum by 1,000 to convert from Wh to kWh. For the per-cycle energy use 
metrics, this value would be divided by the proposed annual active use 
cycles per year.
---------------------------------------------------------------------------

    \12\ Active washing mode for dishwashers includes washing, 
rinsing, and drying, and active cooking mode for conventional 
cooking products includes oven self-clean functions. DOE also 
proposed that delay start mode for both dishwashers and conventional 
cooking products are part of active mode, along with cycle finished 
mode for conventional cooking products. Cycle finished mode for 
cooking products would be considered a part of active mode because 
it would not persist indefinitely after a cooking cycle. Cycle 
finished mode for dishwashers was proposed as a standby mode because 
it could persist indefinitely after an active washing cycle.
---------------------------------------------------------------------------

    As an alternate approach, DOE 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. DOE retained these proposals in the 
September 2011 SNOPR.
    DOE received multiple comments in response to the December 2010 
NOPR regarding the proposed approaches for measuring energy use in low-
power modes as well as the allocation of hours associated with each 
low-power mode. ASAP and the NOPR Joint Comment stated that, although 
currently the annual energy consumption in certain non-active modes may 
represent a small fraction of total annual energy consumption, DOE 
should establish test procedures that include measurements of energy 
consumption in each non-active mode to incentivize manufacturers to 
reduce power consumption in these modes. ASAP commented that DOE should 
consider not just those products that are currently on the market, but 
those that may be introduced in the next 5 or 7 years as well. ASAP and 
the NOPR Joint Comment stated that if the test procedures do not 
measure power consumption in each non-active mode, the energy 
consumption of any new features in these modes that are introduced to 
products will not be captured. (ASAP, Public Meeting Transcript, No. 10 
at pp. 87-88, 109; NOPR Joint Comment, No. 13 at pp. 5-6) The SNOPR 
Joint Comment supported the approach of measuring delay start and all 
non-active modes separately. (SNOPR Joint Comment, No. 22 at pp. 1-2) 
NEEA commented that if DOE defines cycle finished mode as an inactive 
mode, then the energy consumption in all standby and off modes must be 
measured as part of the test procedure, and the hours spent in each 
component of the inactive mode must be based on at least some data from 
the testing of actual products in the field. (NEEA, No. 11 at p. 5).
    Whirlpool supports using the proposed alternate approach, which 
would specify hours for the off and inactive modes when calculating 
energy use. According to Whirlpool, delay start and cycle finished 
modes should not be separately measured because they represent a de 
minimus amount of annual energy use. (Whirlpool, No. 12 at p. 5). 
Whirlpool commented that under the original proposal, testing burden is 
increased by adding requirements to measure cycle finished mode, 
inactive mode, and off mode. Whirlpool estimated the time required for 
the measurement of standby mode and off mode power under the alternate 
approach as 10 minutes per product, as compared to 45 minutes if each 
standby mode and off mode were measured separately. According to 
Whirlpool, multiplying the added 35 minutes by the 100 tests it 
conducts each year results in an increase in test burden of 7-8 man-
days per year, which is a 3-percent productivity loss for the company. 
Whirlpool stated that the cost and complexity of measuring cycle 
finished and off/inactive modes individually greatly exceeds the value 
of such an approach. (Whirlpool, No. 21 at pp. 2-3) AHAM stated that, 
although it objected to the annual hours allocated to the various 
modes, it believes that the alternative approach is preferable to the 
measurement of power consumption in each mode for dishwashers and 
conventional cooking products. (AHAM, No. 14 at pp. 9, 12).
    Today's SNOPR does not propose to include provisions to measure 
delay start mode or cycle finished mode separately from the active 
washing or cooking mode. Instead, today's SNOPR proposes the alternate 
approach, in which all low-power modes are allocated to the inactive 
and off modes, depending on which of these modes is present. DOE 
believes that its assumption set forth in the December 2010 NOPR that 
the power consumption in each of these low-power modes is similar 
remains valid, 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.
    DOE is, however, proposing to require separate measurement of fan-
only mode. The power consumption and duration of this mode may vary 
significantly from product to product, and the energy use associated 
with this mode may in some cases represent a larger percentage of 
annual energy consumption than the energy use in the low-power modes. 
For the dishwasher test procedure, DOE is proposing to require the 
measurement of the energy consumption and duration of fan-only mode for 
each cycle run as part of the test procedure, averaging these values 
when multiple cycles are required (i.e., for soil-sensing dishwashers). 
This energy consumption would be required to be included in the annual 
energy consumption metric upon the compliance date of any updated 
dishwasher energy conservation standards addressing standby mode and 
off mode energy use. For conventional ovens, DOE is proposing to 
require measuring the energy consumption and duration of fan-only mode 
at the end of the active mode heating cycle. This energy consumption 
would be included in the integrated energy factor and integrated annual 
energy consumption metrics.
    DOE is also proposing provisions in the amended dishwasher test 
procedure that would include the machine energy consumption, water 
consumption, and water-heating energy consumption associated with the 
active mode function of water softener regeneration. DOE analysis 
suggests that the water consumption for an active cycle including water 
softener regeneration is typically more than 10 percent higher than the 
water consumption for an

[[Page 31452]]

active cycle without regeneration. Therefore, for machines with built-
in water softening systems, one of the proposed methods to measure this 
additional energy and water consumption would require that two normal 
cycles be run with no dishware load and with the water softening system 
set to the setting corresponding to a water hardness of 217 mg/L and 
with salt provided to the system per the manufacturer's instructions. 
The resulting water consumption for the two cycles would then be 
compared. If the water consumption for either cycle is greater than the 
other by more than 10 percent, then the cycle with the higher water 
consumption would be deemed to have a regeneration process, and the 
difference in water consumption between the two cycles would be 
determined to be the incremental water consumption associated with 
regeneration, and the incremental machine energy consumption for 
regeneration would be the difference in machine energy consumption for 
the two cycles. If neither cycle consumed an amount of water that is 10 
percent higher than for the other cycle, additional cycles would be run 
until the water consumption for a cycle is 10 percent higher than the 
average of the water use for the previous cycles, with the incremental 
regeneration water consumption determined to be the highest water 
consumption minus the average water consumption from the previous 
cycles. The incremental machine energy consumption would be the machine 
energy consumption for cycle with the highest water consumption minus 
the average machine consumption from the previous cycles. The 
incremental regeneration machine and water consumption would be 
apportioned to each active mode cycle, to be considered as part of the 
energy conservation standard metrics, by multiplying by the number of 
annual regeneration processes (36) and dividing by the annual use 
cycles (215). These products should also be multiplied by (1--
percentage of households with home water softening systems), but as 
noted in section III.B, DOE does not have information on such a 
percentage and thus is not including this factor in the calculations 
proposed in today's SNOPR. If a total of 10 cycles are run without 
meeting the threshold criterion, the dishwasher would be deemed not to 
be a water-softening dishwasher for the purposes of the dishwasher test 
procedure. In either case, the DOE test procedure would be conducted 
immediately following this portion of the test, with the water softener 
system set to its lowest water hardness setting.
    The water-heating energy associated with water-softening 
dishwashers that operate at a nominal 120[emsp14][deg]F or 
140[emsp14][deg]F inlet temperature would be calculated as 
(regeneration water consumption per active cycle) x (the temperature 
rise from the nominal cold water temperature of 50[emsp14][deg]F to the 
nominal inlet water temperature) x (specific heat of water, 0.0024 kWh 
per gallon per [deg]F) for electric water heaters. For gas-heated or 
oil-heated water, the water-heating energy would be calculated as 
(regeneration water consumption per active cycle) x (the temperature 
rise from the nominal cold water temperature of 50[emsp14][deg]F to the 
nominal inlet water temperature) x (specific heat of water, 8.2 Btus 
per gallon per [deg]F)/(the nominal heat recovery efficiency of a gas 
or oil water heater, 0.75).
    DOE also proposes an alternate method to account for the machine 
energy consumption, water consumption, and water heating consumption 
associated with water softener regeneration. Under the alternate 
approach, for those units with built-in water softening systems, 
manufacturers would add constant values for these amounts. Based on 
manufacturer data, these amounts can range from 23 gallons/year--47.6 
gallons/year and 4 kWh/year--8 kWh/year. DOE seeks comments and data on 
appropriate constant values, as well as whether the constant values 
should vary based on certain criteria.

D. Dishwasher Test Procedure Clarifications

    During recent implementation of the dishwasher test procedure in 
third-party labs, interested parties raised questions regarding the 
appropriate interpretation of certain provisions. DOE is proposing 
clarifications to these provisions in order to ensure that the 
procedure is uniformly applied during testing. The proposed amendments 
discussed in this section would apply to all dishwasher testing upon 
the effective date of the amended test procedure (i.e., 30 days after 
the date of publication of the test procedure final rule in the Federal 
Register).
1. Normal Cycle Definition
    The DOE dishwasher current defines the normal cycle as ``the cycle 
type recommended by the manufacturer for completely washing a full load 
of normally soiled dishes including the power-dry feature.'' (Section 
1.6 of 10 CFR part 430, subpart B, appendix C) DOE is aware that 
certain dishwashers have multiple wash and/or drying temperature 
options for the cycle setting required under the normal cycle 
definition. For these dishwashers, DOE clarifies in the definition that 
the normal cycle shall include the wash and drying temperature options 
recommended by the manufacturer for completely washing a full load of 
normally soiled dishes including the power-dry feature. DOE seeks 
comment on the wash and drying temperature options to be selected in 
the case that the cycle setting required under the normal cycle 
definition has multiple wash and/or drying temperature options but the 
manufacturer does not provide such a recommendation.
2. Power Supply Requirements
    The current DOE dishwasher test procedure defines a soil-sensing 
dishwasher as ``a dishwasher that has the ability to adjust any energy 
consuming aspect of a wash cycle based on the soil load of the 
dishes.'' (Section 1.12 of appendix C) For certain soil-sensing 
dishwashers, DOE is aware that the turbidity sensor may lose its 
calibration during a power supply interruption. DOE observed, for 
example, during its energy testing of a limited sample of soil-sensing 
dishwashers that the first cycle after a power supply interruption 
consumed as much as 30-percent higher energy and 50-percent higher 
water than subsequent cycles. As a result, removing the power supply to 
these units in between energy test cycles may lead to unrepresentative 
results. DOE also recognizes that, for soil-sensing units, any 
turbidity sensor calibration must be completed prior to conducting the 
water softening regeneration test and active mode cycle according to 
newly proposed sections 4.1 and 4.2 of appendix C, respectively. 
Therefore, DOE proposes that, for soil-sensing dishwashers: (1) the 
cycle setting for the active mode cycle (in which the soil sensor is 
active) be selected for the preconditioning cycle described in newly 
proposed section 2.9 of appendix C, and (2) the power supply to the 
unit be continuously maintained throughout testing, including after the 
preconditioning cycle and in between all energy test cycles.
3. Energy Test Cycle Selection
    DOE is aware of certain soil-sensing dishwasher models that contain 
a soil-sensing cycle selection separate from a non-soil-sensing normal 
cycle. Such a cycle, if selected as the test cycle, may lead to lower 
water and energy use, as the unit would be unable to differentiate 
between the loads for sensor heavy, sensor medium, and sensor light

[[Page 31453]]

response as specified in current sections 1.9, 1.10, and 1.11 of 
appendix C. As a result, testing such units using an energy test cycle 
without soil-sensing may lead to unrepresentative results. Therefore, 
DOE proposes 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 proposes 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).
4. Test Load Specifications and Soiling Requirements
    For soil-sensing dishwashers, the current dishwasher test procedure 
provides instructions in section 2.6.3 of appendix C on the preparation 
of the test loads for the sensor heavy, sensor medium, and sensor light 
response. In each case, the test load is defined as a number of place 
settings plus serving pieces, as specified in section 2.7 of appendix 
C, and a subset of those place settings must be soiled according to 
ANSI/AHAM DW-1-1992, ``Household Electric Dishwashers'' (DW-1-1992), 
while the remaining place settings, serving pieces, and all flatware 
are not soiled. DOE recognizes that while individual dishware, 
glassware, and flatware items are specified in section 2.7 of appendix 
C, the test procedure does not define which items a ``place setting'' 
comprises. Although not referenced specifically in appendix C, DW-1-
1992 defines a place setting as the dishware, glasses, and flatware 
associated with a table serving for one person, which consists of one 
cup, one saucer, one dinner plate, one bread and butter plate, one 
fruit bowl, one glass, one dinner fork, one salad fork, one knife, and 
two teaspoons. DW-1-1992 also defines ``serving pieces'' as the 
dishware and flatware used on the table, which include one platter, two 
serving bowls, two serving spoons, and one serving fork. Because DW-1-
1992 includes flatware items in a place setting, DOE believes that the 
instructions in section 2.6.3 of appendix C to soil a certain number of 
place settings may be interpreted to conflict with the additional 
requirement that all flatware items remain unsoiled. Therefore, DOE 
proposes to amend section 2.7 of appendix C to specify the individual 
items in a place setting and 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.
    DOE notes that certain items specified for the test load in section 
2.7 of appendix C may be obsolete and, thus, may not be obtained for 
use in the dishwasher test procedure. In particular, DOE believes that 
the cup and saucer, salad fork, serving fork and serving spoon are no 
longer available as currently specified. AHAM submitted information to 
DOE regarding alternative specifications for all flatware and serving 
pieces, which AHAM considers acceptable for use in its current 
dishwasher test method, DW-1-2009. AHAM provides specific pattern names 
and product numbers for each of the flatware and serving piece items. 
(AHAM, No. 24 at pp. 1-2) DOE believes that AHAM's specifications 
represent the most reasonable alternative for the obsolete test load 
flatware and serving pieces, and proposes in today's SNOPR to amend the 
test load specifications in section 2.7 of appendix C accordingly. DOE 
also seeks comment on alternative specifications for other test load 
items which may be obsolete, including the cup and saucer, and will 
consider additional amendments to the test load specifications in 
appendix C if it receives such information.
5. Detergent Dosing Specifications
    The current DOE dishwasher test procedure requires the use of half 
the quantity of detergent specified by DW-1-1992. Section 4.1 of ANSI/
AHAM DW-1-1992 requires the use of 0.5-percent concentration by weight 
of Cascade powder national formula dishwasher detergent in the prewash 
and main wash cup. Thus, appendix C requires 0.25-percent detergent 
concentration by weight in the prewash and main wash cup, but it does 
not specify what water usage should be used as the basis for 
calculating the concentrations and how the actual detergent weights 
would be determined.
    Therefore, DOE proposes to calculate the required detergent amounts 
by measuring the volume of water (in gallons) used during the prewash 
and the main wash portions of the cycle when running the 
preconditioning cycle as specified in appendix C. To ensure 
representative water volumes, DOE proposes requiring that the 
preconditioning cycle be run using the cycle setting for the active 
mode cycle. The amount of detergent in grams (g) required for the 
prewash would then be calculated as (volume of water used during the 
prewash portion) x (water density in pounds (lb)/gallon, which is a 
function of the nominal inlet water temperature) x (453.6 g/lb, the 
conversion factor from lb to g) x (0.0025, the conversion factor to 
obtain 0.25-percent mass concentration). The amount of detergent in 
grams required for the main wash would be calculated as (volume of 
water used during the main wash portion) x (water density in lb/gallon, 
which is a function of the inlet water temperature) x (453.6 g/lb, 
which is the conversion factor from lb to g) x (0.0025, the conversion 
factor to obtain 0.25-percent mass concentration).
    DOE is also aware that the detergent specified in section 4.1 of 
ANSI/AHAM DW-1-1992, ``Cascade powder national formula,'' is not a 
currently-marketed formulation. Thus, DOE proposes amending the 
dishwasher test procedure to specify the use of ``Cascade with the 
Grease Fighting Power of Dawn'' powder detergent, which it believes to 
be the most representative Cascade power national formulation available 
at this time on the market.

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

    On July 22, 2011, DOE received a request for guidance from AHAM on 
interpreting the appropriate version of AHAM's dehumidifier test 
method, DH-1, ``Dehumidifiers'' (DH-1), to be used in the DOE 
dehumidifier test procedure found at 10 CFR part 430, subpart B, 
appendix X (appendix X). According to AHAM, it is ambiguous as to 
whether the appropriate version of DH-1 is the one that was in effect 
at the time that the current DOE test procedure was published (AHAM DH-
1-1992 (DH-1-1992)) or the current version that was issued in 2008 
(ANSI/AHAM DH-1-2008 (DH-1-2008)). AHAM recommended that the DOE test 
procedure be interpreted to require the use of DH-1-2008 because it 
contains technical improvements and clarifications as compared to the 
earlier version. (AHAM, No. 23 at pp. 1-2).
    Currently, section 4 of appendix X requires that dehumidifier 
capacity and EF be evaluated by means of the ENERGY STAR qualification 
criteria that were in effect as of January 1, 2001. Those criteria 
(denoted as version 1.0) in turn require that capacity be measured 
according to DH-1, with no version specified, and EF be measured 
according to CAN/CSA-C749-1994 (R2005), ``Performance of 
Dehumidifiers'' (CAN/CSA-C749). DOE agrees that the required test 
method for capacity measurement could be interpreted as either the 
version of DH-1 that was in effect as of January 1, 2001 (DH-1-1992), 
or the version that is currently effective (DH-1-2008).
    DOE, therefore, evaluated both the 1992 and 2008 editions of DH-1 
to

[[Page 31454]]

compare results from the 2008 version with results from the 1992 
version. A review of each edition reveals that the updated provisions 
that could affect the capacity measurement refer to measurement 
equipment accuracy, test room specifications, and data recording 
frequency. Other changes, including the addition of EF measurement 
methodology equivalent to that in CAN/CSA-C749, do not impact the 
capacity measurement. Each of the substantive changes is detailed in 
the following sections.
1. Temperature Measurement Accuracy
    DH-1-1992 requires thermometers measuring wet-bulb and dry-bulb 
temperatures to be accurate to 0.1[emsp14][deg]F, with graduated 
intervals of no more than 0.2[emsp14][deg]F. DH-1-2008 maintains those 
accuracies for analog temperature measurement devices, but requires a 
precision of 0.05[emsp14][deg]F for digital equipment. DOE believes 
that many test labs are already using thermocouples and data 
acquisition systems, and thus achieving the more accurate temperature 
measurements. In any event, this requirement would maintain or improve 
the determination of ambient conditions, leading to maintaining or 
improving test repeatability and reproducibility.
2. Weight Measurement Accuracy
    DH-1-2008 allows the use of less accurate weight measurement 
equipment for measuring the amount of condensate that is collected 
during the test. This newer version requires a maximum of 0.5 percent 
variation among individual readings, rather than the 0.2 percent 
specified in DH-1-1992. Because this allowable variation directly 
translates to a 0.5-percent uncertainty in the capacity rating, the 
effect of this change would be to allow the capacity ratings to range 
from 15  .08 pints/day for the smallest unit in DOE's 
compliance certification database \13\ to 150  .75 pints/
day for the largest unit. While a 0.2-percent uncertainty allows enough 
variation to produce a change in the significant digits of the metric 
used for capacity classification, i.e., two digits after the decimal 
point, this greater allowable uncertainty could result in any 
dehumidifiers being rated at a lower capacity than they would by using 
DH-1-1992.
---------------------------------------------------------------------------

    \13\ DOE's Compliance Certification Database is available online 
at: www.regulations.doe.gov/certification-data/Category.html.
---------------------------------------------------------------------------

3. Barometric Pressure Measurement Accuracy
    DH-1-2008 adds a new requirement that the barometric pressure 
measuring instrument must be accurate to 0.3 percent. DOE is not aware 
of the type of pressure instruments that have been or are currently 
being used by test labs, so it is not known whether this new 
requirement would have any impact on nominal performance measurements. 
DOE believes in general, however, that providing such a specification 
would help ensure test repeatability and reproducibility by aiding in 
maintaining ambient conditions closely.
4. Test Room Requirements
    In DH-1-2008, AHAM increased the minimum distance between any room 
surface and the discharge side of the dehumidifier from 3 feet to 6 
feet. This version of DH-1 also adds a requirement that the test room 
conditioning equipment handle air at a rate of not less than two times 
the dehumidifier air flow, and that the air flow approaching the 
dehumidifier be uniform in velocity. Further, DH-1-2008 newly specifies 
the orientation of the dehumidifier with respect to the air flow within 
the test room and the position of an air sampling tree in relation to 
the inlet face of the test unit. DOE interprets that the purpose of 
these new requirements is to ensure that testing conditions are as 
stable and uniform as possible, and does not believe that the different 
requirements would measurably affect the nominal performance of a test 
unit.
5. Data Recording Intervals
    Measurements of the energy use, supply power, and wet- and dry-bulb 
temperatures are required to be recorded at 30-minute intervals in DH-
1-1992. The intervals were shortened to 10 minutes in the 2008 version. 
This change would not cause a change in the nominal capacity 
measurement because the final condensate measurement would remain the 
same. The greater recording frequency helps to ensure that proper test 
conditions are maintained throughout the test. There is, however, an 
accompanying increase in test burden, as the new test procedure 
requires recording 36 events over the 6-hour test period instead of the 
original 12, but DOE concludes that the incremental burden is small if 
the data are recorded automatically in a data acquisition system, as is 
likely for many test labs.
    In sum, upon review of the two versions of DH-1, DOE recognizes 
that there could be minor impacts to the nominal capacity measurement 
associated with the changes made from DH-1-1992 to DH-1-2008. However, 
DOE tentatively concludes that, on balance, the use of either version 
would produce comparable results for its dehumidifier test procedure. 
Further, DOE believes that the additional clarity and specificity 
provided by the 2008 version would improve test accuracy, 
repeatability, and reproducibility.
    DOE further proposes that the dehumidifier test procedure directly 
reference DH-1-2008 for both the capacity and EF measurements given 
that the EF methodology has been added to DH-1-2008. The proposed test 
method is based on the ENERGY STAR criteria (as required by EPCA) and 
CAN/CSA-C794-1994. DOE proposes the direct reference to DH-1-2008 given 
the improvements in that version as compared to the test method set 
forth in DH-1-1992 and referenced in the ENERGY STAR criteria. 
Therefore, DOE proposes in today's SNOPR to update the reference in its 
dehumidifier test procedure to DH-1-2008 for both capacity and EF 
measurements, and eliminate the reference to the ENERGY STAR 
qualification criteria.

F. Technical Corrections

    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 proposes 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-heater 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, DOE believes that this qualification may cause 
confusion. Therefore, DOE proposes to remove this qualification in 
newly designated sections 5.6.1.1 and 5.6.2.1. DOE also proposes 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.

[[Page 31455]]

    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 proposes in today's 
SNOPR to remove these extraneous variables to correct the calculation.

G. 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). 
Therefore, the provisions in the cooking products test procedure that 
measure the energy use of gas pilot lights shall be obsolete at the 
time any final test procedure amendments become effective. For this 
reason, DOE proposes to delete existing sections 2.9.2.2 (``Flow 
meter''), 3.1.1.2 (``Continuously burning pilot lights of a 
conventional gas oven''), 3.1.2.1 (``Continuously burning pilot lights 
of a conventional gas cooking top''), 3.2.1.3 (``Gas consumption of 
continuously burning pilot lights'' [for conventional gas ovens]), 
3.2.2.1 (``Gas consumption of continuously burning pilot lights'' [for 
conventional gas cooking tops]), 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), 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), 4.1.2.2 (``Annual energy consumption 
of any continuously burning pilot lights'' [for conventional gas 
ovens]), and 4.2.2.2.2 (``Annual energy consumption of any continuously 
burning gas pilots'' [for conventional gas cooking tops]) in 10 CFR 
part 430 subpart B appendix I. DOE also proposes to modify (and 
renumber where appropriate) existing sections 1.7 (``Normal 
nonoperating temperature''), 1.14 (``Symbol usage''), 2.9.2.1 
(``Positive displacement meters''), 3.1.1 ``Conventional oven''), 
3.1.1.1 (``Self-cleaning operation of a conventional oven''), 3.1.2 
(``Conventional cooking top''), 4.1.2.5.2 (``Conventional gas oven 
energy consumption''), 4.1.2.6.2 (``Conventional gas oven energy 
consumption'' [for multiple conventional gas ovens'']), 4.2.1.2 (``Gas 
surface unit cooking efficiency''), and 4.2.2.2.3 (``Total annual 
energy consumption of a conventional gas cooking top'') to eliminate 
the measures of energy use relating to gas pilot lights.
    DOE also proposes 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.

H. Compliance With Other EPCA Requirements

    EPCA requires that ``[a]ny 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)).
    For the reasons stated in the December 2010 NOPR and September 2011 
SNOPR, DOE tentatively concluded 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. DOE continues to make these 
assertions for today's SNOPR, as explained below.
    Regarding the proposal in today's SNOPR to measure energy use in 
fan-only mode, DOE recognizes that the current specifications for the 
watt-hour meter to be used for measuring energy consumption in the 
dishwasher active washing cycle and conventional cooking products 
cooking cycle may not be sufficient. Therefore, DOE is proposing more 
stringent specifications for these watt-hour meters. The watt-hour 
meter in the dishwasher and conventional cooking products test 
procedures would be required to have a resolution of 0.1 watt-hour or 
less and a maximum error of no more than 1 percent of the measured 
value for any demand greater than 5 watts. Today's proposal would allow 
the measurement of fan-only mode energy consumption as a continuation 
of the active mode cycle, rather than necessitating a separate cycle to 
be run to measure the energy use in fan-only mode using the more 
accurate watt-meter. The proposed approach would minimize test burden 
associated with the measurement of fan-only mode.
    For the 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 proposes 
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. DOE welcomes comment on this approach, as well as the 
alternative approach to add constant values for this energy and water 
use, which could reduce the test burden on manufacturers. DOE also 
seeks comment on any other alternative methods to initiate, identify, 
and measure the water softener regeneration process.
    The proposed clarifications for dishwasher test load and soiling 
specifications would not impact test burden because the test conduct 
would remain the same. The proposed clarification of the energy test 
cycle selection for certain soil-sensing dishwashers could change the 
test duration if the cycle time for the non-soil-sensing normal cycle 
and required soil-sensing cycles are different, but the time could be 
shorter or longer depending on the specific model. For the proposed 
detergent dosing clarifications, test burden may be reduced, as the 
amendments would provide clear instructions on the appropriate method 
by which to determine the dosing amounts. DOE welcomes comment on the 
impacts of these proposed clarifications.
    As discussed in section III.E, today's proposal to reference AHAM 
DH-1-2008 in the dehumidifier test procedure would newly specify the 
precision of digital temperature measurement devices for measuring wet-
bulb and dry-bulb temperatures and the accuracy of the barometric 
pressure measurement instrument. DOE estimates the retail cost of such 
equipment as approximately $500. The proposed dehumidifier amendments 
would also allow the use of less accurate weight measurement equipment, 
which imposes no burden on manufacturers. The proposed test room 
requirements, however, 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. Many test laboratories may

[[Page 31456]]

already be using AHAM DH-1-2008 and thus may meet these requirements. 
In addition, for those laboratories that are recording data manually, 
the proposed shortened data recording intervals could result in three 
times the data recording events than are currently required. Because 
only four parameters are recorded for each event, however, the total 
increase in operator time is estimated to be less than 1 hour. DOE 
welcomes comment on the potential burden of the test room and data 
recording requirements for today's proposal, including the prevalence 
of automatic data recording.

IV. Procedural Issues and Regulatory Review

    DOE has concluded that the determinations made pursuant to the 
various procedural requirements applicable to the December 2010 NOPR 
and September 2011 SNOPR remain unchanged for this SNOPR. These 
determinations are set forth in the December 2010 NOPR (75 FR 75290, 
75317-19 (Dec. 2, 2010)) and the September 2011 SNOPR (76 FR 58346, 
58355 (Sept. 20, 2011)). An update to the Regulatory Flexibility Act 
certification is set forth below.
    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 (August 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.
    DOE reviewed today's supplemental proposed rule under the 
provisions of the Regulatory Flexibility Act and the procedures and 
policies published on February 19, 2003. DOE tentatively concluded that 
the December 2010 NOPR and September 2011 SNOPR would not have a 
significant impact on a substantial number of small entities, and 
today's SNOPR contains no revisions to that proposal that would result 
in a significant impact on a substantial number of small entities. The 
updates to the factual basis for this certification are 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, titled ``Other Major Household Appliance 
Manufacturing,'' is 500 employees; this classification specifically 
includes residential dishwasher manufacturers. Additionally, the 
threshold number for NAICS classification code 335221, titled 
``Household Cooking Appliance Manufacturing,'' is 750 employees; this 
classification specifically includes manufacturers of residential 
conventional cooking products. The threshold number for NAICS 
classification code 335211, titled ``Electric Housewares and Household 
Fan Manufacturing,'' is 750 employees; this classification specifically 
includes manufacturers of dehumidifiers.
    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 estimates that there are two 
small businesses that manufacture conventional cooking products, four 
small businesses that manufacture dehumidifiers, and no small 
businesses that manufacture dishwashers.
    The proposed rule would amend DOE's test procedures for 
dishwashers, dehumidifiers and cooking products. Because DOE is unaware 
of any small businesses that manufacture dishwashers, there would be no 
impact on such manufacturers due to the proposed amendments to DOE's 
dishwasher test procedure. The proposed rule would amend 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 would be 
conducted in the same facilities used for the current energy testing of 
these products, so there would be no additional facilities costs 
required by the proposed 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 proposed meter requirements, but 
an Internet search of equipment that specifically meets the proposed 
requirements reveals a cost of approximately $2,000. The amendments 
proposed in today's SNOPR would also update the industry test method 
for dehumidifiers. As discussed in section III.H, this update could 
impose on manufacturers a cost for new measurement equipment of 
approximately $500, as well as potentially increasing operator time by 
less than 1 hour over the course of a 24-hour test. These costs 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,\14\ DOE estimates that the small dehumidifier 
and cooking product businesses have annual revenues of $10 million to 
$60 million.
---------------------------------------------------------------------------

    \14\ Annual revenue estimates based on financial reports 
obtained from Hoover's Inc., available online at www.hoovers.com.
---------------------------------------------------------------------------

    DOE recognizes that the proposed updated reference to the industry 
dehumidifier test method could potentially require manufacturers to 
install a larger test chamber and different air handling equipment. 
However, DOE believes that manufacturers may already be using 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. DOE believes that testing that this laboratory performs for 
manufacturers to determine compliance with energy conservation 
standards would be conducted in the same facility. Therefore, DOE 
tentatively

[[Page 31457]]

concludes that small businesses would not be likely to require 
investments in facility upgrades if DOE amends the dehumidifier test 
procedure to reference DH-1-2008.
    Furthermore, the duration of the fan-only mode testing for 
conventional ovens and conventional ranges is generally not expected to 
exceed the time required to conduct current energy testing. DOE's 
research indicates that the duration of fan-only mode for these 
products ranges from 10 minutes to 3.5 hours. 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 which are 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 3-88 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 DOE believes it is unlikely that these 
manufacturers would be impacted by the proposed fan-only mode testing 
provisions.
    For these reasons, DOE continues to certify that the proposed rule 
would 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 will transmit 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). DOE 
seeks comment on the updated certification set forth above.

B. Issues on Which DOE Seeks Comment

    Although comments are welcome on all aspects of this rulemaking, 
DOE is particularly interested in receiving comments and views of 
interested parties on the following issues:
1. Fan-Only Mode
    DOE seeks comment on the proposal to measure energy use in fan-only 
mode. DOE also seeks comment on its analysis of fan-only mode for 
dishwashers and conventional cooking products. In particular, DOE 
welcomes input on its definition of fan-only mode, its determination of 
fan-only mode as an active mode, its proposed test procedure amendments 
to measure fan-only mode energy use for dishwashers and conventional 
ovens, and the inclusion of fan-only mode energy use in the efficiency 
metrics for these products. (See section III.A).
2. Dishwasher Water Softener Regeneration
    DOE seeks comment on the proposal to measure water softener 
regeneration energy and water consumption for residential dishwashers. 
DOE also requests data on the number of times per year on average that 
the water softening regeneration process occurs, the percentage of 
households with water-softening dishwashers that use home water 
softening systems, and the average per-cycle and annual water and 
energy use associated with water softener regeneration. DOE also 
welcomes input on the methodologies proposed in today's SNOPR to 
measure the water and energy use during regeneration, including the 
method of adding constant values for this water and energy use, and 
what those constant values should be. (See section III.B).
3. Alternative Methodology for Calculating Annual Energy Use
    DOE invites comment on the proposed use of the alternative 
methodology for allocation of annual hours for each product. (See 
section III.C).
4. Dishwasher Test Procedure Clarifications
    DOE invites comment on the approach to ensure the turbidity sensor 
in soil-sensing dishwashers remains calibrated; the method to select 
the energy test cycle to be used for soil-sensing dishwasher testing; 
the clarified definition of normal cycle; the specifications for the 
test load, including alternatives for obsolete items including 
flatware, serving pieces, and possibly other items such as the cup and 
saucer; the method and calculations for preconditioning and determining 
the quantity of detergent to be added to the prewash and main wash 
portions of the test cycle; and the proposed detergent formulation. 
(See section III.C).
5. Updated Dehumidifier Test Procedure
    DOE seeks comment on the proposed incorporation by reference of 
ANSI/AHAM DH-1-2008 for the measurement of capacity and energy factor, 
and the calculation of integrated energy factor in DOE's dehumidifier 
test procedure. (See section III.E).
6. Obsolete Measures of Gas Pilot Light Energy Use
    DOE welcomes comment on its proposal to remove the provisions in 
the cooking products test procedure that measure gas pilot light energy 
consumption. (See section III.G).
7. Test Burden
    DOE seeks comment on its analysis of the test burden associated 
with dishwasher and conventional cooking products fan-only mode testing 
and dishwasher water softener regeneration testing as proposed in 
today's SNOPR, as well as its proposals related to the power supply and 
preconditioning requirements, the energy test cycle for dishwashers 
with a soil-sensing cycle selection separate from a non-soil-sensing 
normal cycle, the test load and soiling requirements, and the detergent 
dosage for dishwashers. DOE also seeks comment on the burden associated 
with updating the industry test method for dehumidifiers. (See sections 
III.A and III.B).
8. Small Businesses
    DOE seeks comment on its tentative conclusion and certification 
that the December 2010 NOPR, as modified by the September 2011 SNOPR 
and today's SNOPR, would not have a significant economic impact on a 
substantial number of small entities.

4. Test Cycle and Measurements

    4.1 Water softener regeneration for water-softening dishwashers. 
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 2.6.1.1, 2.6.2.1, or 
2.6.3.1 of this appendix, initiating the cycle, and allowing the 
cycle to proceed to completion.
    4.1.1 Measure the water consumption, VWS,i, expressed 
as the number of gallons of water delivered to the machine during 
the entire test cycle, using a water meter as specified in section 
3.3 of this appendix, where i is the number of times the cycle has 
been conducted. Measure the machine electrical energy consumption, 
MWS,i, expressed as the number of kilowatt-hours of 
electricity consumed by the machine during the entire test cycle, 
using a watt-hour meter as specified in section 3.5 of this 
appendix.
    4.1.2 Repeat the cycle as specified in section 4.1.1 of this 
appendix. If:
[GRAPHIC] [TIFF OMITTED] TP25MY12.000

    Then VWSmax is defined as the larger of 
VWS,1 and VWS,2, and VWSavg is 
defined as the smaller of VWS,1 and VWS,2; and 
MWSmax is defined as the machine electrical energy 
consumption for the cycle associated with VWSmax, and 
MWSavg is defined as the machine electrical energy 
consumption for the cycle associated with VWSavg;
    Otherwise, repeat the cycle as specified in section 4.1.1 of 
this appendix until:
[GRAPHIC] [TIFF OMITTED] TP25MY12.001

Then,

VWSmax = VWS,i
MWSmax = MWS,i
[GRAPHIC] [TIFF OMITTED] TP25MY12.002

and

[[Page 31465]]

[GRAPHIC] [TIFF OMITTED] TP25MY12.003

    Otherwise, if a maximum total of 10 cycles have been conducted 
and no cycle is determined to have water consumption that is 10 
percent higher than the average water consumption of the other 
cycles, then the unit shall be deemed not a water-softening 
dishwasher.
    4.2 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, 2.6.2.2, or 2.6.3.2 of this appendix, initiating the cycle, 
and allowing the cycle to proceed to completion.
    4.2.1 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.
    4.2.2 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 the fan-only mode after the completion of each test 
cycle, using a watt-hour meter as specified in section 3.5 of this 
appendix. Record the time in minutes that the machine remains in 
fan-only mode, LF.
    4.2.3 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.
    4.3 Simplified standby mode power. Connect the dishwasher to a 
standby wattmeter or a standby watt-hour meter as specified in 
sections 3.6 and 3.7, respectively, of this appendix. Select the 
conditions necessary to achieve operation in the simplified standby 
mode as defined in section 1.19 of this appendix. Monitor the power 
consumption but allow the dishwasher to stabilize for at least 5 
minutes. Then monitor the power consumption for at least an 
additional 5 minutes. If the power level does not change by more 
than 5 percent from the maximum observed value during the later 5 
minutes and if there is no cyclic or pulsing behavior of the load, 
the load can be considered stable. For stable operation, simplified 
standby mode power, Sm, can be recorded directly from the 
standby watt meter in watts or accumulated using the standby watt-
hour meter over a period of at least 5 minutes. For unstable 
operation, the energy must be accumulated using the standby watt-
hour meter over a period of at least 5 minutes and must capture the 
energy use over one or more complete cycles. Calculate the average 
simplified standby mode power, Sm, expressed in watts by 
dividing the accumulated energy consumption by the duration of the 
measurement period.
    4.4 Standby mode and off mode power. Connect the dishwasher to a 
standby mode and off mode watt meter as specified in section 3.8 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 5.1, 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 
5.3.2 of IEC 62301 for testing in each possible mode as described in 
sections 4.4.1 and 4.4.2 of this appendix.
    4.4.1 If the dishwasher has an inactive mode, as defined in 
section 1.10 of this appendix, measure and record the average 
inactive mode power of the dishwasher, PIA, in watts.
    4.4.2 If the dishwasher has an off mode, as defined in section 
1.11 of this appendix, measure and record the average off mode 
power, POM, in watts.

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 related to standby mode and off mode energy 
consumption of conventional ranges, conventional cooking tops, and 
conventional ovens made after (date 180 days after date of 
publication of the test procedure final rule in the Federal 
Register) and of microwave ovens made after September 6, 2011 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.
    1.4 Cycle finished mode means a standby mode in which a 
conventional cooking top, 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 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, as indicated 
to the consumer.
    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 nonoperating temperature means the temperature of 
all areas of an appliance to be tested are within 5[emsp14][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.

3. Test Methods and Measurements

    3.1 Test methods.
    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 nonoperating temperature as defined in 
section 1.12 of this appendix 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 nonoperating temperature as defined in section 
1.12 of this appendix 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 5.1, 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 5.3.2 of IEC 62301 (Second 
Edition) for testing in each possible mode as described in sections 
3.1.1.2.1 and 3.1.1.2.2

[[Page 31469]]

of this appendix. For units in which power varies as a function of 
displayed time in standby mode, either: (1) Set the clock time to 
3:23 at the end of the stabilization period specified in section 5.3 
of IEC 62301 (First Edition) (incorporated by reference; see Sec.  
430.3), and use the average power approach described in section 
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; or (2) at any starting clock 
time, allow a stabilization period as described in section 5.3 of 
IEC 62301 (First Edition), and use the average power approach 
described in section 5.3.2(a) of IEC 62301 (First Edition), but with 
a single test period of 12 hours +0/-30 sec. Testing may be 
conducted using either a 12-hour test, a 10-minute test, or both 
tests; however, if a manufacturer elects to perform both tests on a 
unit, the manufacturer may only use the results from one of the test 
(i.e., the 12-hour test or the 10-minute test) as the test results 
for that unit. Results of the 10-minute test that are within 2 percent of the 12-hour test are deemed to be representative 
of average energy use.
    3.1.1.2.1 If the conventional oven has an inactive mode, as 
defined in section 1.11 of this appendix, measure and record the 
average inactive mode power of the conventional oven, 
PIA, in watts.
    3.1.1.2.2 If the conventional oven has an off mode, as defined 
in section 1.13 of this appendix, measure and record the average off 
mode power of the conventional oven, POM, in watts.
    3.1.2 Conventional cooking top. Establish the test conditions 
set forth in section 2, Test Conditions, of this appendix. Turn off 
the gas flow to the conventional oven(s), if so equipped. The 
temperature of the conventional cooking top shall be its normal 
nonoperating temperature as defined in section 1.12 of this appendix 
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.
    3.1.2.1 Conventional cooking top 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 cooktops that take some time to enter a stable state 
from a higher power state as discussed in section 5.1, Note 1 of IEC 
62301 (Second Edition) (incorporated by reference; see Sec.  430.3), 
allow sufficient time for the conventional cooking top to reach the 
lower power state before proceeding with the test measurement. 
Follow the test procedure as specified in section 5.3.2 of IEC 62301 
(Second Edition) for testing in each possible mode as described in 
sections 3.1.2.1.1 and 3.1.2.1.2 of this appendix. For units in 
which power varies as a function of displayed time in standby mode, 
either: (1) set the clock time to 3:23 at the end of the 
stabilization period specified in section 5.3 of IEC 62301 (First 
Edition) (incorporated by reference; see Sec.  430.3), and use the 
average power approach described in section 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; or (2) at any starting clock time, allow a 
stabilization period as described in section 5.3 of IEC 62301 (First 
Edition), and use the average power approach described in section 
5.3.2(a) of IEC 62301 (First Edition), but with a single test period 
of 12 hours +0/-30 sec. Testing may be conducted using either a 12-
hour test, a 10-minute test, or both tests; however, if a 
manufacturer elects to perform both tests on a unit, the 
manufacturer may only use the results from one of the tests (i.e., 
the 12-hour test or the 10-minute test) as the test results for that 
unit. Results of the 10-minute test that are within 2 
percent of the 12-hour test are deemed to be representative of 
average energy use.
    3.1.2.1.1 If the conventional cooking top has an inactive mode, 
as defined in section 1.11 of this appendix, measure and record the 
average inactive mode power of the conventional cooking top, 
PIA, in watts.
    3.1.2.1.2 If the conventional cooking top has an off mode, as 
defined in section 1.13 of this appendix, measure and record the 
average off mode power of the conventional cooking top, 
POM, in watts.
    3.1.3 Conventional range 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 
ranges that take some time to enter a stable state from a higher 
power state as discussed in section 5.1, Note 1 of IEC 62301 (Second 
Edition) (incorporated by reference; see Sec.  430.3), allow 
sufficient time for the conventional range to reach the lower power 
state before proceeding with the test measurement. Follow the test 
procedure as specified in section 5.3.2 of IEC 62301 (Second 
Edition) for testing in each possible mode as described in sections 
3.1.3.1 and 3.1.3.2 of this appendix. For units in which power 
varies as a function of displayed time in standby mode, either: (1) 
set the clock time to 3:23 at the end of the stabilization period 
specified in section 5.3 of IEC 62301 (First Edition) (incorporated 
by reference; see Sec.  430.3), and use the average power approach 
described in section 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; or (2) at 
any starting clock time, allow a stabilization period as described 
in section 5.3 of IEC 62301 (First Edition), and use the average 
power approach described in section 5.3.2(a) of IEC 62301 (First 
Edition), but with a single test period of 12 hours +0/-30 sec. 
Testing may be conducted using either a 12-hour test, a 10-minute 
test, or both tests; however, if a manufacturer elects to perform 
both tests on a unit, the manufacturer may only use the results from 
one of the test (i.e., the 12-hour test or the 10-minute test) as 
the test results for that unit. Results of the 10-minute test that 
are within 2 percent of the 12-hour test are deemed to 
be representative of average energy use.

higher power state to a lower power state as discussed in section 
5.1, Note 1 of IEC 62301 (First Edition) (incorporated by reference; 
see Sec.  430.3), allow sufficient time for the microwave oven to 
reach the lower power state before proceeding with the test 
measurement. Follow the test procedure as specified in section 5.3 
of IEC 62301 (First Edition). For units in which power varies as a 
function of displayed time in standby mode, set the clock time to 
3:23 and use the average power approach described in section 
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. If a microwave oven is capable of

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 Test measurements.

(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,

VA, VB, VC, and VD 
should be expressed in standard cubic feet (L) of gas for

    6. Appendix X to subpart B of part 430 is revised to read as 
follows:

Appendix X to Subpart B of Part 430--Uniform Test Method for Measuring 
the Energy Consumption of Dehumidifiers

    Note: The procedures and calculations that refer to standby mode 
and off mode energy consumption (i.e., sections 3.2, 3.2.1 through 
3.2.4, 4.2, 4.2.1 through 4.2.4, 5.1, and 5.2 of this appendix) need 
not be performed to determine compliance with energy conservation 
standards for dehumidifiers at this time. However, any 
representation related to standby mode and off mode energy 
consumption of these products made after (date 180 days after date 
of publication of the test procedure final rule in the Federal 
Register) 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 for any energy conservation standards that 
incorporate standby mode and off mode energy consumption, compliance 
with the applicable provisions of this test procedure will be 
required.

1. Scope

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

2. Definitions

    a. 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).
    b. 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.
    c. Bucket full/removed mode means a standby mode in which the 
dehumidifier has automatically powered off its main function by 
detecting when the water bucket is full or has been removed.
    d. 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).
    e. 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).
    f. 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.
    g. 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.
    h. 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.
    i. 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.
    j. 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

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 4.4 of IEC 62301 (incorporated 
by reference, see Sec.  430.3).
