[Docket No. EERE-2012-BT-TP-0013]
RIN 1904-AC71
Energy Conservation Program: Test Procedures for Conventional
Ovens
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: On December 3, 2014, the U.S. Department of Energy (DOE)
issued a supplemental notice of proposed rulemaking (SNOPR) to amend
the test procedures for conventional cooking products. The oven-related
procedures proposed in that rulemaking serve as the basis for this
final rule. As part of the SNOPR, DOE proposed to incorporate methods
for measuring conventional oven volume, clarified that the existing
oven test block must be used to test all ovens regardless of input
rate, and proposed a method to measure the energy consumption of
conventional ovens equipped with an oven separator. Additionally, DOE
proposed technical corrections to the units of measurement in certain
calculations. This final rule amends the current procedure to include
the proposed changes listed above, as well as clarifications to certain
definitions, that will take effect 30 days after the final rule
publication date. These changes will be mandatory for product testing
to demonstrate compliance with any new or amended energy conservation
standards when they take effect and for representations of the energy
consumption of conventional ovens starting 180 days after publication.
DATES: The effective date of this rule is August 3, 2015. The final
rule changes will be mandatory for product testing starting December
29, 2015. The incorporation by reference of certain publications listed
in this rule was approved by the Director of the Federal Register as of
August 3, 2015.

I. Authority and Background
Title III of the Energy Policy and Conservation Act of 1975 (42
U.S.C. 6291, et seq.; ``EPCA'' or, ``the Act'') sets forth a variety of
provisions designed to improve energy efficiency. (All references to
EPCA refer to the statute as amended through the Energy Efficiency
Improvement Act of 2015, Public Law 114-11 (Apr. 30, 2015). Part B of
Title III, which for editorial reasons was redesignated as Part A upon
incorporation into the U.S. Code (42 U.S.C. 6291-6309, as codified),
establishes the ``Energy Conservation Program for Consumer Products
Other Than Automobiles.'' These include cooking products,\1\ and
specifically consumer conventional ovens, the subject of this document.
(42 U.S.C. 6292(a)(10))
---------------------------------------------------------------------------
\1\ DOE's regulations define kitchen ranges and ovens, or
``cooking products'', as one of the following classes: Conventional
ranges, conventional cooking tops, conventional ovens, microwave
ovens, microwave/conventional ranges and other cooking products. (10
CFR 430.2) Based on this definition, DOE interprets kitchen ranges
and ovens to refer more generally to all types of cooking products
including, for example, microwave ovens.
---------------------------------------------------------------------------
Under EPCA, the energy conservation program consists essentially of
four parts: (1) Testing, (2) labeling, (3) Federal energy conservation
standards, and (4) certification and enforcement procedures. The
testing requirements consist of test procedures that manufacturers of
covered products must use as the basis for (1) certifying to DOE that
their products comply with the applicable energy conservation standards
adopted under EPCA, and (2) making representations about the efficiency
of those products. Similarly, DOE must use these test procedures to
determine whether the products comply with any relevant standards
promulgated under EPCA.
A. General Test Procedure Rulemaking Process
Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures
DOE must
[[Page 37955]]
follow when prescribing or amending test procedures for covered
products. EPCA provides that any test procedures prescribed or amended
under this section shall be reasonably designed to produce test results
which measure energy efficiency, energy use or estimated annual
operating cost of a covered product during a representative average use
cycle or period of use and shall not be unduly burdensome to conduct.
(42 U.S.C. 6293(b)(3))
In addition, if DOE determines that a test procedure amendment is
warranted, it must publish proposed test procedures and offer the
public an opportunity to present oral and written comments on them. (42
U.S.C. 6293(b)(2)) Finally, in any rulemaking to amend a test
procedure, DOE must determine to what extent, if any, the proposed test
procedure would alter the measured energy efficiency of any covered
product as determined under the existing test procedure. (42 U.S.C.
6293(e)(1))
This final rule fulfills, in part, DOE's obligation to periodically
review its test procedures under 42 U.S.C. 6293(b)(1)(A). DOE
anticipates that its next evaluation of this test procedure for
conventional ovens will occur in a manner consistent with the timeline
set out in this provision.
B. Test Procedures for Cooking Products
DOE's test procedures for conventional ranges, conventional cooking
tops, conventional ovens, and microwave ovens are codified at appendix
I to subpart B of Title 10 of the Code of Federal Regulations (CFR)
part 430 (Appendix I).
DOE established the test procedures in a final rule published in
the Federal Register on May 10, 1978. 43 FR 20108, 20120-20128. DOE
revised its test procedures 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 International
Electrotechnical Commission (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 procedures for conventional cooking products establish
provisions for determining estimated annual operating cost, cooking
efficiency (defined as the ratio of cooking energy output to cooking
energy input), and energy factor (defined as the ratio of annual useful
cooking energy output to total annual energy input). 10 CFR 430.23(i);
Appendix I. These provisions for conventional cooking products are not
currently used for compliance with any energy conservation standards
because the present standards are design requirements, and there is not
an EnergyGuide \2\ labeling program for cooking products.
---------------------------------------------------------------------------
\2\ For more information on the EnergyGuide labeling program,
see: www.access.gpo.gov/nara/cfr/waisidx_00/16cfr305_00.html.
---------------------------------------------------------------------------
DOE subsequently conducted a rulemaking to address standby and off
mode energy consumption, as well as certain active mode testing
provisions, for dishwashers, dehumidifiers, and conventional cooking
products. DOE published a final rule on October 31, 2012 (77 FR 65942,
hereinafter referred to as the October 2012 Final Rule), adopting
standby and off mode provisions that satisfy the EPCA requirement that
DOE include measures of standby mode and off mode energy consumption in
its test procedures for residential products, if technically feasible.
(42 U.S.C.6295(gg)(2)(A))
C. The January 2013 NOPR
On January 30, 2013, DOE published a NOPR (78 FR 6232, hereinafter
referred to as the January 2013 NOPR) proposing amendments to Appendix
I that would allow for measuring the active mode energy consumption of
induction cooking products; i.e., conventional cooking tops and ranges
equipped with induction heating technology for one or more surface
units \3\ on the cooking top. DOE proposed to incorporate induction
cooking tops by amending the definition of ``conventional cooking top''
to include induction heating technology. Furthermore, DOE proposed to
require for all cooking tops the use of test equipment compatible with
induction technology. Specifically, DOE proposed to replace the solid
aluminum test blocks currently specified in the test procedure for
cooking tops with hybrid test blocks comprising two separate pieces: An
aluminum body and a stainless steel base. In the January 2013 NOPR, DOE
also proposed amendments to include a clarification that the test block
size be determined using the smallest dimension of the electric surface
unit. 78 FR 6232 (Jan. 30, 2013).
---------------------------------------------------------------------------
\3\ The term surface unit refers to burners for gas cooking
tops, electric resistance heating elements for electric cooking
tops, and inductive heating elements for induction cooking tops.
---------------------------------------------------------------------------
D. The December 2014 SNOPR
On December 3, 2014, DOE published a supplemental NOPR (SNOPR) (79
FR 71894, hereinafter referred to as the December 2014 SNOPR),
modifying its proposal from the January 2013 NOPR to more accurately
measure the energy efficiency of induction cooking tops. DOE proposed
to add a layer of thermal grease between the stainless steel base and
aluminum body of the hybrid test block to facilitate heat transfer
between the two pieces. DOE also proposed additional test equipment for
electric surface units with large diameters (both induction and
electric resistance) and gas cooking top burners with high input rates.
79 FR 71894 (Dec. 3, 2014). In addition, DOE proposed methods to test
non-circular electric surface units, electric surface units with
flexible concentric cooking zones, and full-surface induction cooking
tops. Id. Furthermore, DOE proposed to incorporate methods for
measuring conventional oven volume, clarify that the existing oven test
block must be used to test all ovens regardless of input rate, and
provide a method to measure the energy consumption and efficiency of
conventional ovens equipped with an oven separator. Id.
E. Conventional Cooking Top Active Mode Test Procedures
DOE received a number of comments from interested parties on the
cooking top active mode test procedure proposed in the December 2014
SNOPR. The majority of comments stated that additional analysis was
necessary before establishing a test procedure for conventional cooking
tops. AHAM requested an extension of the comment period for the
December 2014 SNOPR, citing the difficulty its members had procuring
the specified test equipment materials. Therefore, AHAM stated, many
manufacturers were not able to properly assess the new specifications,
testing variation, repeatability, and reproducibility of the proposed
test procedure before the comment period closed. (AHAM, No. 14 at p. 1)
\4\ AHAM also expressed concern with DOE's choice to pursue an
accelerated rulemaking schedule for cooking products, stating that the
rulemaking schedule did not allow for a thorough technical examination.
AHAM asked
[[Page 37956]]
DOE to seek additional input from interested parties on the December
2014 SNOPR and commented that the proposed cooking top test procedure
may result in technical problems. (AHAM, No. 18 at pp. 1-2)
---------------------------------------------------------------------------
\4\ A notation in the form ``AHAM, No. 14 at p. 1'' identifies a
written comment (1) made by AHAM; (2) recorded in document number 14
that is filed in the docket of this cooking products test procedures
rulemaking (Docket No. EERE-2012-BT-TP-0013) and maintained in the
Resource Room of the Building Technologies Program; and (3) which
appears on page 1 of document number 14.
---------------------------------------------------------------------------
BSH Home Appliances Corporation (BSH) and General Electric
Appliances (GE) stated that delays associated with acquiring the hybrid
test block materials necessitated additional time for them to evaluate
DOE's proposal. (BSH, No. 16 at p. 2; GE, No. 17 at p. 1) BSH commented
that the proposed hybrid test block method did not include certain
specifications necessary for test procedure reproducibility, such as
test load sizing and positioning, and recommended that DOE consider the
specifications in International Electrotechnical Commission (IEC)
Standard 60350-2 Edition 2, ``Household electric appliances--Part 2:
Hobs--Method for measuring performance'' (IEC Standard 60350-2). (BSH,
No. 16 at p. 1) Further, AHAM, BSH, and GE suggested that DOE specify
additional test block diameters because these commenters asserted that
the proposed test block sizes do not adequately reflect surface unit
sizes currently available on the market. (BSH, No. 16 at p. 5; GE, No.
17 at p 2; AHAM, No. 18 at p. 2)
Interested parties also expressed a significant number of concerns
with the use of thermal grease. GE noted that since receiving DOE's
proposal, it has not been able to replicate the DOE test results using
the methods described. (GE, No. 17 at p. 2) Specifically, GE observed
during its testing that the aluminum body slid off the stainless steel
base, the thermal grease dried out, and the amount of grease between
the blocks changed from one test to another. (GE, No. 17 at p. 2) AHAM,
BSH, and GE requested that DOE specify an operating temperature range
for the thermal grease as well as an application thickness, but also
noted that the thermal conductivity and viscosity of the grease may
change over time or after repeated use at high temperatures. (BSH, No.
16 at p. 11; GE, No. 17 at p. 2; AHAM, No. 18 at p. 3) GE further
commented that the variation introduced by the hybrid test block due to
the inability to reliably maintain the specified flatness, thermal
grease, and inadequate sizing, may be small individually, but
collectively result in a test procedure that cannot reliably discern
efficiency differences between similar products, alternate technology
options, and product classes. Thus, GE believes the proposal for
conventional cooking tops in the December 2014 SNOPR results in too
much variability to serve as the basis for establishing a standard.
(GE, No. 17 at p. 3)
The California IOUs also stated that they prefer an alternative to
the hybrid test block and recommended that DOE require water-heating
test methods to measure the cooking efficiency of conventional cooking
tops. Specifically, the California IOUs requested that DOE align the
residential cooking product test methods with existing industry test
procedures, such as American Society for Testing and Materials (ASTM)
standard F1521-12, Standard Test Methods for Performance of Range Tops,
and IEC Standard 60350-2, Household electric cooking appliances--Part
2: Hobs--Methods for measuring performance. (California IOUs, No. 19 at
p. 1) The California IOUs commented that they plan to conduct
additional testing to better characterize the differences between the
water-heating and hybrid test block test procedures, and will provide
these results to DOE. According to the California IOUs, the differences
in test procedure standard deviation between the hybrid test block and
water-heating test method as presented in the December 2014 SNOPR did
not sufficiently show that the hybrid test block method is more
repeatable than a water-heating method. (California IOUs, No. 19 at p.
2) Additionally, the California IOUs believe cooking efficiencies
derived using a water-heating test method are more representative of
the actual cooking performance of cooking tops as opposed to a test
procedure using hybrid test blocks, since many foods prepared on
cooktops have relatively high liquid content. (California IOUs, No. 19
at p. 1)
In February and March of 2015, DOE conducted a series of interviews
with manufacturers of conventional cooking products representing the
majority of the U.S. market to discuss key issues with the proposed
cooking top test procedure. Manufacturers agreed that the hybrid test
block method, as proposed, presented many issues which had not yet been
addressed, and which left the repeatability and reproducibility of the
test procedure in question. These concerns were similar to those
expressed in written comments but were received from a larger group of
manufacturers and included:
Difficulty obtaining the hybrid test block materials;
Difficulty obtaining and applying the thermal grease
without more detailed specifications (i.e., thermal conductivity alone
was not sufficient to identify a grease that performed according to
DOE's descriptions in the December 2014 SNOPR);
Difficulty testing induction cooking tops that use
different programming techniques to prevent overheating (some
manufacturers observed that power to the heating elements cut off
prematurely during testing with the hybrid test block even after adding
thermal grease); and
The need for larger test block sizes to test electric
surface units having 12-inch and 13-inch diameters and gas surface
units with high input rates.
Interviewed manufacturers that produce and sell products in Europe
uniformly supported the use of a water-heating test method and
harmonization with IEC Standard 60350-2 for measuring the energy
consumption of electric cooking tops. These manufacturers cited the
benefits of adopting a test method similar to the IEC water-heating
method as including: (1) Compatibility with all electric cooking top
types, (2) additional test vessel diameters to account for the variety
of surface unit sizes on the market, and (3) the test load's ability to
represent a real-world cooking top load.
After reviewing public comments and information received during
manufacturer interviews, as well as performing additional analyses, DOE
concluded that further study is required before a cooking top test
procedure can be established that produces test results which measure
energy use during a representative average use cycle, is repeatable and
reproducible, and is not unduly burdensome to conduct. For these
reasons, this final rule addresses test methods for conventional ovens
only, including conventional ovens that are a part of conventional
ranges. This final rule also addresses minor technical corrections to
existing calculations and definitions in Appendix I for both
conventional cooking tops and ovens.
DOE plans to address test procedures for cooking tops in a separate
rulemaking in order to consider any additional data and information
that will allow it to further conduct the analysis of cooking tops,
particularly when using a water-heating method to evaluate energy
consumption. As part of that rulemaking, DOE will carefully consider
and address remaining cooking top-related comments on the December 2014
SNOPR.
II. Summary of the Final Rule
This final rule amends the current DOE test procedure for
conventional ovens. These changes will primarily clarify the manner in
which to test for compliance with potential energy conservation
standards for conventional ovens. The final rule establishes that the
existing oven test block should be used to test all ovens, including
ovens having
[[Page 37957]]
input rates greater than 22,500 British thermal units per hour (Btu/h).
The final rule additionally amends the current DOE test procedure to
include test methods for conventional ovens equipped with an oven
separator. Conventional ovens equipped with an oven separator shall be
tested in each possible oven configuration (i.e., full oven cavity,
upper cavity, and lower cavity), with the results averaged.
Because Appendix I does not currently contain a measure of
conventional oven volume, the final rule incorporates by reference in
the DOE test procedure the relevant sections of AHAM Standard OV-1-2011
``Procedures for the Determination and Expression of the Volume of
Household Microwave and Conventional Ovens'' (AHAM-OV-1-2011) for
determining conventional oven cavity volume. As part of its rulemaking
that is considering amended standards for conventional ovens, DOE
proposed standards as a function of oven cavity volume.
Additionally, this final rule is clarifying the current definitions
for ``freestanding'' and ``built-in'' installation configurations.
Because the manufacturer instructions of some conventional ovens state
the oven can be used in either a freestanding or built-in
configuration, this final rule is clarifying that ovens with this
option be tested in the built-in configuration, as ovens designed to be
used in a built-in configuration incorporate fan-only mode for thermal
management, and the energy consumption of these products is likely
higher than for comparable ovens designed for use only in a
freestanding configuration. Furthermore, the final rule is clarifying
the term ``self-cleaning operation'' when referring to an oven's self-
cleaning process. The existing test procedure in Appendix I does not
include an explicit definition, although section 3 of Appendix I, Test
Methods and Measurements, requires measurement of self-cleaning
operation.
Finally, the final rule includes technical corrections to the
calculation of derived results from test measurements in section 4 of
Appendix I. Section 4 contains a number of references to incorrect
units of measurement and an incorrect value for the annual useful
cooking energy output for gas cooking tops. The final rule also
restores headings for sections 4.2 and 4.2.1 in Appendix I regarding
the calculations for conventional cooking tops, which were
inadvertently removed in the October 2012 Final Rule.
III. Discussion
A. Products Covered by This Test Procedure Rulemaking
As discussed in section I of this final rule, section 6292(a)(10)
of EPCA covers kitchen ranges and ovens, or ``cooking products.'' DOE's
regulations define ``cooking products'' as consumer products that are
used as the major household cooking appliances. They are designed to
cook or heat different types of food by one or more of the following
sources of heat: Gas, electricity, or microwave energy. Each model may
consist of a horizontal cooking top containing one or more surface
units \5\ and/or one or more heating compartments. Cooking products
include the following classes: Conventional ranges, conventional
cooking tops, conventional ovens, microwave ovens, microwave/
conventional ranges and other cooking products. (10 CFR 430.2) In this
final rule, DOE is addressing test procedures for conventional ovens.
---------------------------------------------------------------------------
\5\ The term surface unit refers to burners for gas cooking
tops, electric resistance heating elements for electric cooking
tops, and inductive heating elements for induction cooking tops.
---------------------------------------------------------------------------
DOE notes that conventional ranges are defined in 10 CFR 430.2 as a
class of kitchen ranges and ovens which is a household cooking
appliance, consisting of a conventional cooking top and one or more
conventional ovens. Because ranges consist of both a cooking top and at
least one oven, any potential cooking top energy conservation standard
or oven energy conservation standard would apply to each of these
cooking systems individually. Thus, the test procedures presented in
this final rule also apply to the oven portion of a conventional range.
As part of the previous energy conservation standards rulemaking
for conventional cooking products, DOE decided not to analyze
conventional gas cooking products with higher burner input rates,
including products marketed as ``commercial-style'' or ``professional-
style,'' in its consideration of energy conservation standards due to a
lack of available data for determining the efficiency characteristics
of those products. At the time, DOE considered commercial-style ovens
to be gas ovens with burner input rates greater than 22,500 Btu/h. 74
FR 16040, 16054 (Apr. 8, 2009); 72 FR 64432, 64444-64445 (Nov. 15,
2007). In the December 2014 SNOPR, DOE noted that the current
definitions for ``conventional oven'' and ``conventional range'' in 10
CFR 430.2 already cover conventional gas ovens with higher input rates
(including commercial-style gas ovens), as these products are household
cooking appliances with compartments intended for the cooking or
heating of food by means of a gas flame.
Sub-Zero Group, Inc. (Sub-Zero) commented that DOE's findings based
on manufacturer feedback in the previous energy conservation standards
rulemaking are still relevant. Specifically, the small market size, the
limited energy savings potential, and the lack of energy consumption
data for ovens with high input rates are reasons to exclude these
products from coverage. (Sub-Zero, No. 20 at pp. 2, 3) Sub-Zero further
commented that ``high performance'' is a better descriptor of cooking
products with high input rates rather than ``commercial-style,'' noting
that the ``high performance'' segment appeals to consumers demanding
restaurant-style cooking performance in their homes. (Sub-Zero, No. 20
at p. 2) Sub-Zero suggested that high performance (i.e., ``commercial-
style'') products be defined as cooking products that offer residential
consumers restaurant-quality performance at a safety and convenience
level that is acceptable for residential use. (Sub-Zero, No. 20 at p.
2)
DOE excluded ``commercial-style'' conventional gas ovens from its
analysis in the previous energy conservation standards rulemaking due
to a lack of available data for determining efficiency characteristics
of those products. 74 FR 16040, 16054 (Apr. 8, 2009); 72 FR 64432,
64444-64445 (Nov. 15, 2007). As discussed in section III.C of this
final rule, DOE conducted testing in support of the December 2014 SNOPR
that demonstrated that the existing conventional oven test procedure is
appropriate for ovens with high input rates. Additionally, DOE is not
aware of any data or test procedures that establish whether a
conventional oven with burner input rates greater than 22,500 Btu/h
delivers ``restaurant-quality performance'' as compared to an oven with
burner input rates lower than 22,500 Btu/h. Furthermore, through
testing, reverse engineering analyses, and discussions with
manufacturers conducted in support of the concurrent energy
conservation standards rulemaking for cooking products, DOE determined
that the primary differentiation between conventional gas ovens with
lower burner input rates and those with higher input rates, including
those marketed as commercial-style, was design and construction related
to aesthetics rather than improved cooking performance. Some examples
of design and construction related features include
[[Page 37958]]
heavier gauge cavity walls, extra interior support structure for
heavier gauge racks, and ball-bearing extension racks. These features
add to the overall thermal mass that must be heated during the baking
process but do not necessarily improve cooking performance.
For these reasons, DOE notes in this final rule that the current
definitions for ``conventional oven'' and ``conventional range'' in 10
CFR 430.2 already cover conventional gas ovens with higher input rates
(including commercial-style gas ovens), as these products are household
cooking appliances with compartments intended for the cooking or
heating of food by means of a gas flame.
B. Effective Date
The amended test procedure becomes effective 30 days after this
test procedure final rule is published in the Federal Register.
Pursuant to EPCA, manufacturers of covered products must use the
applicable test procedure as the basis for determining that their
products comply with the applicable energy conservation standards
adopted pursuant to EPCA and for making representations about the
efficiency of those products. (42 U.S.C. 6293(c); 42 U.S.C. 6295(s))
Beginning 180 days after publication of this test procedure final rule,
representations related to the energy consumption of conventional ovens
must be based upon results generated under the applicable provisions of
the amended test procedure in Appendix I. (42 U.S.C. 6293(c)(2))
C. Gas Ovens With Input Rates Greater Than 22,500 Btu/h
Because DOE is considering in a separate rulemaking energy
conservation standards for conventional ovens, including gas ovens with
high input rates, DOE evaluated the appropriateness of the existing
test methods in Appendix I for use with conventional gas ovens that
have burner input rates greater than 22,500 Btu/h. In the December 2014
SNOPR, DOE proposed that the existing test methods in Appendix I should
be used to test ovens with high input rates, including gas ovens
marketed as commercial-style. 79 FR 71916 (December 3, 2014).
The current active mode test procedure for conventional ovens
involves setting the temperature control for the normal baking cooking
cycle such that the temperature inside the oven is 325 5
degrees Fahrenheit ([deg]F) higher than the room ambient air
temperature (77 9[emsp14][deg]F). An 8.5-pound (6.25-inch
diameter) cylindrical anodized aluminum test block is then heated in
the oven from ambient room air temperature 4[emsp14][deg]F
until the test block temperature has increased 234[emsp14][deg]F above
its initial temperature. If an oven permits baking by either forced
convection by using a fan, or without forced convection, the oven is
tested using the procedure described above in each of those two cooking
modes. After the baking test(s), if the oven is equipped with a self-
cleaning function, the self-cleaning process is initiated in accordance
with the manufacturer's instruction and allowed to run until
completion. The measured energy consumption during these test cycles is
used to calculate the oven's cooking efficiency and integrated annual
energy consumption (IAEC).\6\
DOE's review of the gas oven cavity volumes currently available on
the U.S. market indicated that there is significant overlap in oven
cavity volume between products marketed as standard, residential-style
ovens and those marketed as commercial-style ovens. The primary
differentiating factor between the two oven types was burner input
rate, which is greater than 22,500 Btu/h for most commercial-style gas
ovens. In the December 2014 SNOPR, DOE investigated the effect of
increasing oven test block size on oven cooking efficiency. DOE sought
to determine whether a larger test block would provide a more
representative measure of cooking efficiency at higher input rates. DOE
also sought to determine whether the smaller block was inadequate to
properly measure the efficiency of commercial-style ovens. In its
testing, DOE found that while cooking efficiency increased with the
larger test block, it scaled by approximately the same factor for all
ovens tested regardless of a particular oven's input rate or cavity
volume, or whether the oven was marketed as residential-style or
commercial-style. The relative ranking of cooking efficiency for ovens
with high input rates as compared to ovens with input rates lower than
22,500 Btu/h did not change with increased test block size. This
suggested that thermal losses are large enough in comparison to the
heat absorbed by either sized test block that they account for much of
the additional oven energy input for ovens with high input rates. Thus,
the thermal losses from the cavity are driven largely by input rate
alone and do not change greatly with increased test block size. 79 FR
71915-71916 (December 3, 2014).
---------------------------------------------------------------------------
\6\ For ovens that can be operated with or without forced
convection, the average of the energy consumption for these two
modes is used. For self-clean mode, the test procedure in Appendix I
assumes an average of 4 self-cleaning operations per year.
---------------------------------------------------------------------------
Sub-Zero stated that the proposed test procedure does not
accurately measure the performance and efficiency of the larger,
higher-output components. (Sub Zero, No. 20 at p. 2) Additionally, Sub-
Zero commented that an analysis based largely on 30-inch wide gas or
electric ranges cannot adequately evaluate the very different
performance attributes offered by high-performance products which are
essential to consumer utility. (Sub-Zero, No. 20 at p. 2) Thus, Sub-
Zero believes that DOE's conclusion that the existing test procedure in
Appendix I is appropriate for ovens with high input rates is incorrect.
(Sub-Zero, No. 20 at p. 3) Sub-Zero requested that high performance
products be exempted until adequate further analysis is conducted such
that these products can be accurately and fairly evaluated. (Sub Zero,
No. 20 at p. 3)
In support of the December 2014 SNOPR and in support of the
parallel energy conservation standards rulemaking for conventional
ovens, DOE tested eight conventional gas ovens that were selected to
capture a range of design features that might impact performance,
including infrared broilers, convection fans, and hidden bake elements.
The basic design features and measured IAEC are shown in Table III-1.
The test sample included 30-inch wide models as well as models with
widths greater than 30 inches. DOE observed that many of the same
features found in gas ovens marketed as commercial-style were also
available in ovens marketed as residential-style. By comparing the
design features and the measured energy consumption of the ovens in its
test sample, DOE determined that the major differentiation between
conventional gas ovens with lower burner input rates and those with
higher input rates, including those marketed as commercial-style, was
design and construction related to aesthetics rather than improved
cooking performance. Available information also indicates that the high
thermal mass of products marketed as commercial-style likely lead to a
low oven cooking efficiency and require higher oven input rates to
compensate for the heat lost to the cavity.

DOE also investigated the time it took each oven in its sample to
heat the test block to the required final temperature of
234[emsp14][deg]F above its initial temperature. As shown in Table III-
2, gas ovens with burner input rates greater than 22,500 Btu/h do not
heat the test block significantly faster than the ovens with lower
burner input rates, and two out of the three units with the higher
burner input rates took longer than the average time to heat the test
block.

Considering the testing results and analysis described above, and
because interested parties did not provide data or information to
support the assertion that the performance of conventional ovens with
input rates greater than 22,500 Btu/h as compared to ovens with lower
input rates cannot be accurately measured using the existing test
procedure, DOE maintains in this final rule that the existing test
block and existing conventional oven test method are appropriate to
test conventional ovens with input rates greater than 22,500 Btu/h.
D. Incorporating by Reference AHAM-OV-1-2011 for Determination of the
Volume of Conventional Ovens
As discussed in section I of this final rule, DOE has initiated a
rulemaking to determine whether to amend the current energy
conservation standards for conventional ovens. As part of that
rulemaking, DOE has proposed standards as a function of oven cavity
volume.
In the December 2014 SNOPR, DOE proposed to amend section 3.1.1 of
Appendix I to incorporate by reference the industry test standard AHAM-
OV-1-2011, which includes a method for determining oven cavity volume.
DOE proposed to incorporate section 3, ``Definition,'' section 5.1,
``General Principles,'' and section 5.2 ``Overall Volume'' of AHAM-OV-
1-2011, as these sections provide a repeatable and reproducible method
to measure cavity dimensions and calculate overall volume by including
clear definitions of oven characteristics and tolerances for
dimensional measurements. 79 FR 71916 (December 3, 2014). Section 5.1
of AHAM-OV-1-2011 specifies that if depressions or cutouts exist in the
cavity wall, dimensions are taken from the plane representing the
largest area of the surface. Section 5.1 of AHAM-OV-1-2011 also
specifies that oven lights, racks, and other removable features shall
be ignored in the overall volume calculation, and the volume of non-
rectangular cavities is calculated by measuring the rectangular portion
of the cavity and non-rectangular cavity separately and adding their
volumes together.
AHAM-OV-1-2011 also includes a measurement of the oven's usable
space, which is the volume inside the oven cavity available for the
placement of food, but DOE did not propose to incorporate this
measurement in Appendix I. The usable space is oven-specific and
determined by measuring either the size of the cavity door aperture or
the distance between barriers, racks, and rack supports inside the
cavity or on the cavity walls. The lesser of these dimensions is used
to calculate the volume of the usable space.
Although DOE did not receive any public comments on its proposal to
[[Page 37960]]
incorporate the overall cavity volume measurement described in section
5.1 and 5.2 of AHAM-OV-1-2011, one manufacturer commented during
interviews conducted in February and March of 2015 that DOE should
instead consider incorporating the usable space measurement described
in section 5.3 of AHAM-OV-1-2011. The manufacturer cited difficulty in
determining the plane representing the largest area of the cavity wall
surface, and also stated that the oven test procedure used by National
Resources Canada (NRCan) bases its energy efficiency regulations on the
volume of usable oven space and not overall cavity volume.
DOE notes that during February and March 2105 manufacturer
interviews conducted to discuss the December 2014 SNOPR, the majority
of manufacturers confirmed that the cavity volume currently published
in marketing materials and product literature typically represents
overall cavity volume. DOE does not believe that requiring this
measurement will place additional burden on manufacturers.
Manufacturers already provide exterior dimensions in the installation
instructions and may also be able to use the configuration and
dimensions of indentions in the oven cavity walls provided in
engineering drawings to determine the plane representing the largest
area of the cavity wall surface. Incorporating a cavity measurement
into Appendix I would, in most circumstances, add only the three
additional measurements of cavity height, width, and depth.
Furthermore, DOE believes the overall cavity volume measurement
provides a more accurate representation of the relationship between
cavity volume and cooking efficiency as measured by the DOE test
procedure in Appendix I. Any mass in the overall cavity volume outside
of the usable space is heated during the bake cycle, contributes to the
thermal mass, and thus impacts the cooking efficiency of the oven.
For the reasons discussed above, DOE amends in this final rule
section 3.1.1 of Appendix I to incorporate by reference Sections 3,
5.1, and 5.2 of AHAM-OV-1-2011 for measuring the overall oven cavity
volume.
E. Conventional Oven Separator
In the December 2014 SNOPR, DOE observed one conventional electric
oven equipped with an oven separator on the U.S. market that allows for
cooking using the entire oven cavity in the absence of the separator
or, if the separator is installed, splitting the oven into two smaller
cavities that may be operated individually with independent temperature
controls. DOE proposed to test conventional ovens equipped with an oven
separator in each possible oven configuration (i.e., full oven cavity,
upper cavity, and lower cavity) with the cooking efficiency and total
annual energy consumption averaged. DOE noted that while the current
test procedure in Appendix I includes provisions for measuring the
energy consumption and cooking efficiency of single ovens and multiple
(separate) ovens,\7\ it does not include provisions for how to test a
single oven that can be configured as a full oven or as two separate
smaller cavities. 79 FR 71916-71917 (December 3, 2014).
---------------------------------------------------------------------------
\7\ For multiple ovens, Appendix I specifies that the energy
consumption and cooking efficiency be calculated as the average of
each individual oven.
---------------------------------------------------------------------------
During the subsequent manufacturer interviews, several
manufacturers commented that without an easy or convenient way to store
the separator, consumers would rarely use the feature. One manufacturer
suggested that DOE consider applying a consumer usage factor to the
oven separator when calculating annual energy consumption instead of
using an equally-weighted average.
DOE is not aware of any consumer usage data indicating how often
consumers might use an oven separator in each configuration.
Additionally, DOE notes that the annual energy consumption of
conventional ovens having multiple, permanent cavities of different
volumes are currently averaged with an equal weighting in the existing
oven test procedure in Appendix I. Therefore, DOE has no basis to adopt
a weighted average of cooking efficiency and annual energy consumption
as part of the test procedure for ovens equipped with an oven
separator. In this final rule, DOE amends the oven test procedure in
Appendix I to require the test of conventional ovens equipped with an
oven separator in each possible oven configuration and to calculate
cooking efficiency and annual energy consumption as an equal average of
the results measured in each configuration.
F. Standby and Off Mode Test Procedure
EPCA requires that DOE amend its test procedures for all covered
consumer products, including conventional ovens, to include measures of
standby mode and off mode energy consumption, if technically feasible.
(42 U.S.C. 6295(gg)(2)(A)) Accordingly, DOE conducted a rulemaking for
conventional cooking products, dishwashers, and dehumidifiers to
address standby and off mode energy consumption.\8\ In the October 2012
Final Rule, DOE addressed standby mode and off mode energy consumption,
as well as active mode fan-only operation, for conventional cooking
products. 77 FR 65942 (Oct. 31, 2012).
---------------------------------------------------------------------------
\8\ DOE pursued amendments to Appendix I addressing standby and
off mode energy for microwave ovens as part of a separate
rulemaking. The final rule for this microwave oven rulemaking
published on January 18, 2013. 78 FR 4015.
---------------------------------------------------------------------------
DOE noted in the December 2014 SNOPR that because conventional gas
ovens with higher input rates are covered under the definition of
``cooking products'' in 10 CFR 430.2, these products are covered by the
standby and off mode test procedures discussed above. During testing of
conventional ovens with both standard and higher input rates in its
test sample, DOE did not observe any standby mode or off mode operation
or features unique to these products that would warrant any changes to
the standby mode and off mode test methods. 79 FR 71917 (December 3,
2014). Because DOE received no comments objecting to these findings,
this final rule does not amend the standby mode and off mode test
methods currently specified in Appendix I section 3.1.
G. Technical Corrections to the Calculation of Derived Results From
Test Measurements
DOE did not receive comments on its proposal to correct the units
of measurement in section 4 of Appendix I nor did DOE receive comments
on its correction of the integrated energy factor for conventional
electric cooking tops, IRCT. In this final rule, DOE
corrects the following sections of Appendix I to reference the
appropriate units: 4.1.2.1.1, 4.1.2.2.1, 4.1.2.4.3, 4.1.2.5.3, 4.1.4.1,
4.1.4.2, 4.2.1.2, 4.2.2.2.1, and 4.2.2.2.2. DOE also corrects the value
of the annual useful cooking energy output, OCT, used to
calculate IRCT, to 173.1 kWh per year.
H. Headings for Conventional Cooking Top Calculations
DOE did not receive comments on its proposal in the December 2014
SNOPR to restore headings to section 4.2 ``Conventional cooking top,''
and section 4.2.1, ``Surface unit cooking efficiency'' in Appendix I to
appropriately describe these sections. Therefore DOE has included these
modifications in this final rule.
I. Clarifying Definitions for Freestanding and Built-In Ovens
Appendix I contains definitions for various cooking product
installation
[[Page 37961]]
conditions and specifies that the unit under test must be installed in
an enclosure in accordance with the manufacturer's instructions. The
test procedure in Appendix I currently defines ``freestanding'' as an
installation configuration where the product is not supported by
surrounding cabinetry, walls, or other similar structures. A ``built-
in'' installation condition means the product is supported by
surrounding cabinetry, walls, or other similar structures. ``Drop-in''
means the product is supported by horizontal surface cabinetry. During
interviews after publication of the December 2014 SNOPR, manufacturers
commented that the current definitions for ``freestanding,'' ``built-
in,'' and ``drop-in'' should be amended. Specifically, manufacturers
noted that some conventional ovens and conventional ranges are designed
to be used in both a freestanding or built-in configuration, and that
it is currently unclear in which configuration the oven should be
tested.
During its testing, DOE observed that built-in ovens consume energy
in fan-only mode, whereas freestanding ovens do not. The additional
energy required to exhaust air from the oven cavity is necessary to
meet safety-related temperature requirements for built-in installation
configurations, in which the oven is enclosed in cabinetry. Because
built-in ovens consume additional energy in fan-only mode, as part of
DOE's ongoing energy conservation standards rulemaking for conventional
ovens, DOE has proposed to establish separate product classes for
built-in and freestanding ovens using the definitions provided in
Appendix I. 80 FR 33030, 33045-46 (June 10, 2015). DOE also recognizes
that the current definition of built-in configurations does not
adequately describe the installation conditions that require built-in
ovens to have a separate fan assembly and fan-only mode.
In this final rule, DOE is clarifying that conventional ovens or
ranges that may be used in either a freestanding or built-in
configuration are to be tested in the built-in configuration to account
for any additional energy-consumption related to fan-only mode in this
configuration. DOE is also clarifying that the definition of built-in
means the product is enclosed in surrounding cabinetry, walls, or other
similar structures on at least three sides.
J. Clarifying Definitions for Oven Self-Cleaning Operation
The existing test procedure in Appendix I does not include a
definition for the self-cleaning operation or self-cleaning process of
conventional ovens, although it specifies the measurement energy
consumption during self-cleaning operation in section 3 Test Methods
and Measurements. The existing test procedure specifies setting the
conventional oven's self-cleaning process in accordance with the
manufacturer's instructions, and if the self-cleaning process is
adjustable, using the average time recommended by the manufacturer for
a moderately soiled oven. DOE is clarifying in the final rule that
self-cleaning operation is an active mode not intended to heat or cook
food that is user-selectable, separate from the normal baking mode, and
dedicated to cleaning and removing cooking deposits from the oven
cavity walls.
K. Compliance With Other EPCA Requirements
EPCA requires that any new or amended test procedures for consumer
products must 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 must not be unduly burdensome to conduct. (42 U.S.C.
6293(b)(3))
As part of the December 2014 SNOPR, DOE tentatively concluded that
the amended test procedures would produce test results that measure the
energy consumption of conventional ovens during representative use, and
that the test procedures would not be unduly burdensome to conduct. 79
FR 71917-71918 (Dec. 3, 2014).
As discussed in section III.C of this document, the final rule
amends the test procedure for gas ovens to require that the existing
test block be used for all ovens, including ovens with high input
rates. DOE does not expect any increase in testing burden compared to
the existing test procedure, since these tests follow the same
methodology, use the same test equipment, and can be conducted in the
same facilities used for the current energy testing of conventional
ovens. As discussed in section III.D of this document, the final rule
also incorporates by reference AHAM-OV-1-2011 for measuring the overall
oven cavity volume. DOE estimates that it would take on the order of
one-half to one hour to conduct the cavity volume measurement for a
single oven, and $50 to $100 per test for labor. Additionally, because
manufacturers may already be using the AHAM procedure to measure oven
cavity volume, DOE does not anticipate this measurement to be unduly
burdensome to conduct. As discussed in section III.E of this document,
the final rule amends the test procedure so that conventional ovens
equipped with an oven separator are tested in each possible oven
configuration. DOE notes, based on its testing, that this may add two
oven tests for the additional cavity configurations, and add
approximately $2,750 for labor. DOE does not believe this additional
cost represents an excessive burden for test laboratories or
manufacturers given the significant investments necessary to
manufacture, test and market consumer appliances.
IV. Procedural Issues and Regulatory Review
A. Review Under Executive Order 12866
The Office of Management and Budget (OMB) has determined that test
procedure rulemakings do not constitute ``significant regulatory
actions'' under section 3(f) of Executive Order 12866, Regulatory
Planning and Review, 58 FR 51735 (Oct. 4, 1993). Accordingly, this
action was not subject to review under the Executive Order by the
Office of Information and Regulatory Affairs (OIRA) in the Office of
Management and Budget (OMB).
B. Review Under the Regulatory Flexibility Act
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires
preparation of an initial regulatory flexibility analysis (IFRA) for
any rule that by law must be proposed for public comment and a final
regulatory flexibility analysis for any such rule that an agency adopts
as a final rule, 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: http://energy.gov/gc/office-general-counsel.
DOE reviewed this final rule under the provisions of the Regulatory
Flexibility Act and the procedures and policies published on February
19, 2003. The final rule clarifies that the existing test method for
ovens is applicable to gas ovens with higher input rates. The final
rule also includes a test method for conventional ovens with oven
separators and incorporates by reference a test method to measure oven
cavity volume.
[[Page 37962]]
The Small Business Administration (SBA) considers a business entity
to be a small business, if, together with its affiliates, it employs
less than a threshold number of workers or earns less than the average
annual receipts specified in 13 CFR part 121. The threshold values set
forth in these regulations use size standards and codes established by
the North American Industry Classification System (NAICS) that are
available at: http://www.sba.gov/sites/default/files/files/Size_Standards_Table.pdf. The threshold number for NAICS classification
code 335221, titled ``Household Cooking Appliance Manufacturing,'' is
750 employees; this classification includes manufacturers of
residential conventional ovens.
Most of the manufacturers supplying conventional ovens are large
multinational corporations. DOE surveyed the AHAM member directory to
identify manufacturers of conventional ovens and conventional ranges.
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 seven small businesses that manufacture
conventional ovens and conventional ranges subject to the proposed test
procedure amendments.
For the reasons stated in the preamble, DOE has concluded that the
final rule would not have a significant impact on small manufacturers
under the applicable provisions of the Regulatory Flexibility Act. The
final rule clarifies that DOE's existing test procedures in Appendix I
for conventional ovens are applicable to conventional ovens with higher
input rates. These tests follow the same methodology, use the same test
equipment, and can be conducted in the same facilities used for the
current energy testing of conventional ovens, so there would be no
additional facility costs required by the final rule. Additionally, the
incorporation by reference of AHAM-OV-1-2011 to measure oven cavity
volume and the addition of a test method to measure conventional ovens
with an oven separator will not significantly impact small
manufacturers under the applicable provisions of the Regulatory
Flexibility Act. DOE estimates a cost of $4,500 for an average small
manufacturer to measure the cavity volume of all of its product
offerings which is only 0.03 percent of the average annual revenue of
the seven identified small businesses. This estimate assumes $100 per
test as described in section III.K of this notice, with up to 44 tests
per manufacturer. Additionally, no small conventional oven
manufacturer, as defined by the SBA, offers a product with an oven
separator.
For these reasons, DOE concludes and certifies that this final 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 has transmitted the
certification and supporting statement of factual basis to the Chief
Counsel for Advocacy of the SBA for review under 5 U.S.C. 605(b).
C. Review Under the Paperwork Reduction Act of 1995
Manufacturers of conventional ovens must certify to DOE that their
products comply with any applicable energy conservation standards. In
certifying compliance, manufacturers must test their products according
to the DOE test procedures for conventional ovens, including any
amendments adopted for those test procedures. DOE has established
regulations for the certification and recordkeeping requirements for
all covered consumer products and commercial equipment, including
conventional ovens. 76 FR 12422 (March 7, 2011). The collection-of-
information requirement for the certification and recordkeeping is
subject to review and approval by OMB under the Paperwork Reduction Act
(PRA). This requirement has been approved by OMB under OMB control
number 1910-1400. In an application to renew the OMB information
collection approval for DOE's certification and recordkeeping
requirements, DOE included an estimated burden for manufacturers of
conventional ovens. OMB has approved the revised information collection
for DOE's certification and recordkeeping requirements through November
30, 2017. 80 FR 5099 (January 30, 2015). DOE estimated that it will
take each respondent approximately 30 hours total per company per year
to comply with the certification and recordkeeping requirements based
on 20 hours of technician/technical work and 10 hours clerical work to
submit the Compliance and Certification Management System templates.
This rulemaking would include recordkeeping requirements on
manufacturers that are associated with executing and maintaining the
test data for this equipment. DOE recognizes that recordkeeping burden
may vary substantially based on company preferences and practices.
Notwithstanding any other provision of the law, no person is
required to respond to, nor shall any person be subject to a penalty
for failure to comply with, a collection of information subject to the
requirements of the PRA, unless that collection of information displays
a currently valid OMB Control Number.
D. Review Under the National Environmental Policy Act of 1969
In this final rule, DOE amends its test procedure for conventional
ovens. DOE has determined that this rule falls into a class of actions
that are categorically excluded from review under the National
Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) and DOE's
implementing regulations at 10 CFR part 1021. Specifically, this rule
amends an existing rule without affecting the amount, quality or
distribution of energy usage, and, therefore, will not result in any
environmental impacts. Thus, this rulemaking is covered by Categorical
Exclusion A5 under 10 CFR part 1021, subpart D, which applies to any
rulemaking that interprets or amends an existing rule without changing
the environmental effect of that rule. Accordingly, neither an
environmental assessment nor an environmental impact statement is
required.
E. Review Under Executive Order 13132
Executive Order 13132, ``Federalism,'' 64 FR 43255 (August 4,
1999), imposes certain requirements on agencies formulating and
implementing policies or regulations that preempt State law or that
have Federalism implications. The Executive Order requires agencies to
examine the constitutional and statutory authority supporting any
action that would limit the policymaking discretion of the States and
to carefully assess the necessity for such actions. The Executive Order
also requires agencies to have an accountable process to ensure
meaningful and timely input by State and local officials in the
development of regulatory policies that have Federalism implications.
On March 14, 2000, DOE published a statement of policy describing the
intergovernmental consultation process it will follow in the
development of such regulations. 65 FR 13735. DOE examined this final
rule and determined that it will not have a substantial direct effect
on the States, on the relationship between the national government and
the States, or on the distribution of power and responsibilities among
the
[[Page 37963]]
various levels of government. EPCA governs and prescribes Federal
preemption of State regulations as to energy conservation for the
products that are the subject of this final rule. States can petition
DOE for exemption from such preemption to the extent, and based on
criteria, set forth in EPCA. (42 U.S.C. 6297(d)) No further action is
required by Executive Order 13132.
F. Review Under Executive Order 12988
Regarding the review of existing regulations and the promulgation
of new regulations, section 3(a) of Executive Order 12988, ``Civil
Justice Reform,'' 61 FR 4729 (Feb. 7, 1996), imposes on Federal
agencies the general duty to adhere to the following requirements: (1)
Eliminate drafting errors and ambiguity; (2) write regulations to
minimize litigation; (3) provide a clear legal standard for affected
conduct rather than a general standard; and (4) promote simplification
and burden reduction. Section 3(b) of Executive Order 12988
specifically requires that Executive agencies make every reasonable
effort to ensure that the regulation: (1) Clearly specifies the
preemptive effect, if any; (2) clearly specifies any effect on existing
Federal law or regulation; (3) provides a clear legal standard for
affected conduct while promoting simplification and burden reduction;
(4) specifies the retroactive effect, if any; (5) adequately defines
key terms; and (6) addresses other important issues affecting clarity
and general draftsmanship under any guidelines issued by the Attorney
General. Section 3(c) of Executive Order 12988 requires Executive
agencies to review regulations in light of applicable standards in
sections 3(a) and 3(b) to determine whether they are met or it is
unreasonable to meet one or more of them. DOE has completed the
required review and determined that, to the extent permitted by law,
this final rule meets the relevant standards of Executive Order 12988.
G. Review Under the Unfunded Mandates Reform Act of 1995
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA)
requires each Federal agency to assess the effects of Federal
regulatory actions on State, local, and Tribal governments and the
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531).
For a regulatory action resulting in a rule that may cause the
expenditure by State, local, and Tribal governments, in the aggregate,
or by the private sector of $100 million or more in any one year
(adjusted annually for inflation), section 202 of UMRA requires a
Federal agency to publish a written statement that estimates the
resulting costs, benefits, and other effects on the national economy.
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to
develop an effective process to permit timely input by elected officers
of State, local, and Tribal governments on a proposed ``significant
intergovernmental mandate,'' and requires an agency plan for giving
notice and opportunity for timely input to potentially affected small
governments before establishing any requirements that might
significantly or uniquely affect small governments. On March 18, 1997,
DOE published a statement of policy on its process for
intergovernmental consultation under UMRA. 62 FR 12820; also available
at http://energy.gov/gc/office-general-counsel. DOE examined this final
rule according to UMRA and its statement of policy and determined that
the rule contains neither an intergovernmental mandate, nor a mandate
that may result in the expenditure of $100 million or more in any year,
so these requirements do not apply.
H. Review Under the Treasury and General Government Appropriations Act,
1999
Section 654 of the Treasury and General Government Appropriations
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family
Policymaking Assessment for any rule that may affect family well-being.
This final rule will not have any impact on the autonomy or integrity
of the family as an institution. Accordingly, DOE has concluded that it
is not necessary to prepare a Family Policymaking Assessment.
I. Review Under Executive Order 12630
DOE has determined, under Executive Order 12630, ``Governmental
Actions and Interference with Constitutionally Protected Property
Rights'' 53 FR 8859 (March 18, 1988), that this regulation will not
result in any takings that might require compensation under the Fifth
Amendment to the U.S. Constitution.
J. Review Under Treasury and General Government Appropriations Act,
2001
Section 515 of the Treasury and General Government Appropriations
Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most
disseminations of information to the public under guidelines
established by each agency pursuant to general guidelines issued by
OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 2002), and
DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has
reviewed this final rule under the OMB and DOE guidelines and has
concluded that it is consistent with applicable policies in those
guidelines.
K. Review Under Executive Order 13211
Executive Order 13211, ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use,'' 66 FR 28355
(May 22, 2001), requires Federal agencies to prepare and submit to OMB,
a Statement of Energy Effects for any significant energy action. A
``significant energy action'' is defined as any action by an agency
that promulgated or is expected to lead to promulgation of a final
rule, and that: (1) Is a significant regulatory action under Executive
Order 12866, or any successor order; and (2) is likely to have a
significant adverse effect on the supply, distribution, or use of
energy; or (3) is designated by the Administrator of OIRA as a
significant energy action. For any significant energy action, the
agency must give a detailed statement of any adverse effects on energy
supply, distribution, or use if the regulation is implemented, and of
reasonable alternatives to the action and their expected benefits on
energy supply, distribution, and use.
This regulatory action is not a significant regulatory action under
Executive Order 12866. Moreover, it would not have a significant
adverse effect on the supply, distribution, or use of energy, nor has
it been designated as a significant energy action by the Administrator
of OIRA. Therefore, it is not a significant energy action, and,
accordingly, DOE has not prepared a Statement of Energy Effects.
L. Review Under Section 32 of the Federal Energy Administration Act of
1974
Under section 301 of the Department of Energy Organization Act
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the
Federal Energy Administration Act of 1974, as amended by the Federal
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA)
Section 32 essentially provides in relevant part that, where a proposed
rule authorizes or requires use of commercial standards, the notice of
proposed rulemaking must inform the public of the use and background of
such standards. In addition, section 32(c) requires DOE to consult with
the Attorney General and the Chairman of the Federal Trade Commission
(FTC) concerning the impact of the commercial or industry standards on
competition.
[[Page 37964]]
The proposed modifications to the test procedures addressed by this
action incorporate testing methods contained in the AHAM OV-1-2011
standard, ``Procedures for the Determination and Expression of the
Volume of Household Microwave and Conventional Ovens.'' DOE has
evaluated this standard and is unable to conclude whether this industry
standard fully complies with the requirements of section 32(b) of the
FEAA, (i.e., that it was developed in a manner that fully provides for
public participation, comment, and review). DOE has consulted with both
the Attorney General and the Chairman of the FTC about the impact on
competition of using the methods contained in these standards and has
received no comments objecting to their use.
M. Congressional Notification
As required by 5 U.S.C. 801, DOE will report to Congress on the
promulgation of this rule before its effective date. The report will
state that it has been determined that the rule is not a ``major rule''
as defined by 5 U.S.C. 804(2).
N. Approval of the Office of the Secretary
The Secretary of Energy has approved publication of this final
rule.

2.9.3.4 of this appendix, as applicable.
* * * * *
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 non-operating temperature as defined in section 1.13 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
[[Page 37965]]
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 [deg]F (130 [deg]C) above its initial temperature.
3.1.1.1 Self-cleaning operation of a conventional oven. If the
conventional oven is capable of operating in a user-selectable self-
cleaning mode, separate from the normal baking mode and dedicated to
cleaning and removing cooking deposits from the oven cavity walls,
establish the test conditions set forth in section 2, Test Conditions,
of this appendix. Turn off the gas flow to the conventional cooking
top. The temperature of the conventional oven shall be its normal non-
operating temperature as defined in section 1.13 and described in
section 2.6 of this appendix. Then set and start the conventional
oven's self-cleaning process in accordance with the manufacturer's
instructions. If the self-cleaning process is adjustable, use the
average time recommended by the manufacturer for a moderately soiled
oven.
3.1.1.2 Conventional oven standby mode and off mode power.
Establish the standby mode and off mode testing conditions set forth in
section 2, Test Conditions, of this appendix. For conventional ovens
that take some time to enter a stable state from a higher power state
as discussed in Section 5, Paragraph 5.1, Note 1 of IEC 62301 (Second
Edition) (incorporated by reference; see Sec. 430.3), allow sufficient
time for the conventional oven to reach the lower power state before
proceeding with the test measurement. Follow the test procedure as
specified in Section 5, Paragraph 5.3.2 of IEC 62301 (Second Edition)
for testing in each possible mode as described in 3.1.1.2.1 and
3.1.1.2.2 of this appendix. For units in which power varies as a
function of displayed time in standby mode, set the clock time to 3:23
at the end of the stabilization period specified in Section 5,
Paragraph 5.3 of IEC 62301 (First Edition), and use the average power
approach described in Section 5, Paragraph 5.3.2(a) of IEC 62301 (First
Edition), but with a single test period of 10 minutes +0/-2 sec after
an additional stabilization period until the clock time reaches 3:33.
3.1.1.2.1 If the conventional oven has an inactive mode, as defined
in section 1.12 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 1.14 of this appendix, measure and record the average off mode
power of the conventional oven, POM, in watts.
3.1.1.3 Conventional oven cavity volume. Measure the oven cavity
volume according to the test procedure specified in Sections 3, 5.1 and
5.2 of AHAM-OV-1 (incorporated by reference; see Sec. 430.3).
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 1.13 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, Paragraph 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, Paragraph 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, set the clock
time to 3:23 at the end of the stabilization period specified in
Section 5, Paragraph 5.3 of IEC 62301 (First Edition), and use the
average power approach described in Section 5, Paragraph 5.3.2(a) of
IEC 62301 (First Edition), but with a single test period of 10 minutes
+0/-2 sec after an additional stabilization period until the clock time
reaches 3:33.
3.1.2.1.1 If the conventional cooking top has an inactive mode, as
defined in section 1.12 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 1.14 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, Paragraph 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, Paragraph 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, set the clock time to 3:23 at the
end of the stabilization period specified in Section 5, Paragraph 5.3
of IEC 62301 (First Edition), and use the average power approach
described in Section 5, Paragraph 5.3.2(a) of IEC 62301 (First
Edition), but with a single test period of 10 minutes +0/-2 sec after
an additional stabilization period until the clock time reaches 3:33.
3.1.3.1 If the conventional range has an inactive mode, as defined
in section 1.12 of this appendix, measure and record the average
inactive mode power of the conventional range, PIA, in
watts.
3.1.3.2 If the conventional range has an off mode, as defined in
section 1.14 of this appendix, measure and record the average off mode
power of the conventional range, POM, in watts.
3.1.4 Microwave oven.
3.1.4.1 Microwave oven test standby mode and off mode power.
Establish the testing conditions set forth in section 2, Test
Conditions, of this appendix. For microwave ovens that drop from a
higher power state to a lower power state as discussed in Section 5,
Paragraph 5.1, Note 1 of IEC 62301 (Second Edition) (incorporated by
reference; see Sec. 430.3), allow sufficient
[[Page 37966]]
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, Paragraph 5.3.2 of IEC 62301 (Second 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, Paragraph 5.3.2(a) of IEC 62301 (First
Edition), but with a single test period of 10 minutes +0/-2 sec after
an additional stabilization period until the clock time reaches 3:33.
If a microwave oven is capable of operation in either standby mode or
off mode, as defined in sections 1.18 and 1.14 of this appendix,
respectively, or both, test the microwave oven in each mode in which it
can operate.
3.2 Test measurements.
3.2.1 Conventional oven test energy consumption. If the oven
thermostat controls the oven temperature without cycling on and off,
measure the energy consumed, EO, when the temperature of the
block reaches TO (TO is 234[emsp14][deg]F (130
[deg]C) above the initial block temperature, TI). If the
oven thermostat operates by cycling on and off, make the following
series of measurements: Measure the block temperature, TA,
and the energy consumed, EA, or volume of gas consumed,
VA, at the end of the last ``ON'' period of the conventional
oven before the block reaches TO. Measure the block
temperature, TB, and the energy consumed, EB, or
volume of gas consumed, VB, at the beginning of the next
``ON'' period. Measure the block temperature, TC, and the
energy consumed, EC, or volume of gas consumed, VC, at the
end of that ``ON'' period. Measure the block temperature,
TD, and the energy consumed, ED, or volume of gas
consumed, VD, at the beginning of the following ``ON''
period. Energy measurements for EO, EA,
EB, EC, and ED should be expressed in
watt-hours (kJ) for conventional electric ovens, and volume
measurements for VA, VB, VC, and
VD should be expressed in standard cubic feet (L) of gas for
conventional gas ovens. For a gas oven, measure in watt-hours (kJ) any
electrical energy, EIO, consumed by an ignition device or
other electrical components required for the operation of a
conventional gas oven while heating the test block to TO.
3.2.1.1 Conventional oven average test energy consumption. If the
conventional oven permits baking by either forced convection or without
forced convection and the oven thermostat does not cycle on and off,
measure the energy consumed with the forced convection mode,
(EO)1, and without the forced convection mode,
(EO)2, when the temperature of the block reaches
TO (TO is 234[emsp14][deg]F (130 [deg]C) above
the initial block temperature, TI). If the conventional oven
permits baking by either forced convection or without forced convection
and the oven thermostat operates by cycling on and off, make the
following series of measurements with and without the forced convection
mode: Measure the block temperature, TA, and the energy
consumed, EA, or volume of gas consumed, VA, at
the end of the last ``ON'' period of the conventional oven before the
block reaches TO. Measure the block temperature,
TB, and the energy consumed, EB, or volume of gas
consumed, VB, at the beginning of the next ``ON'' period.
Measure the block temperature, TC, and the energy consumed,
EC, or volume of gas consumed, VC, at the end of
that ``ON'' period. Measure the block temperature, TD, and
the energy consumed, ED, or volume of gas consumed,
VD, at the beginning of the following ``ON'' period. Energy
measurements for EO, EA, EB,
EC, and ED should be expressed in watt-hours (kJ)
for conventional electric ovens, and volume measurements for
VA, VB, VC, and VD should
be expressed in standard cubic feet (L) of gas for conventional gas
ovens. For a gas oven that can be operated with or without forced
convection, measure in watt-hours (kJ) any electrical energy consumed
by an ignition device or other electrical components required for the
operation of a conventional gas oven while heating the test block to
TO using the forced convection mode,
(EIO)1, and without using the forced convection
mode, (EIO)2.
3.2.1.2 Conventional oven fan-only mode energy consumption. If the
conventional oven is capable of operation in fan-only mode, measure the
fan-only mode energy consumption, EOF, expressed in
kilowatt-hours (kJ) of electricity consumed by the conventional oven
for the duration of fan-only mode, using a watt-hour meter as specified
in section 2.9.1.1 of this appendix. Alternatively, if the duration of
fan-only mode is known, the watt-hours consumed may be measured for a
period of 10 minutes in fan-only mode, using a watt-hour meter as
specified in section 2.9.1.1 of this appendix. Multiply this value by
the time in minutes that the conventional oven remains in fan-only
mode, tOF, and divide by 10,000 to obtain EOF.
The alternative approach may be used only if the resulting
EOF is representative of energy use during the entire fan-
only mode.
3.2.1.3 Energy consumption of self-cleaning operation. Measure the
energy consumption, ES, in watt-hours (kJ) of electricity or
the volume of gas consumption, VS, in standard cubic feet
(L) during the self-cleaning test set forth in section 3.1.1.1 of this
appendix. For a gas oven, also measure in watt-hours (kJ) any
electrical energy, EIS, consumed by ignition devices or
other electrical components required during the self-cleaning test.
3.2.1.4 Standby mode and off mode energy consumption. Make
measurements as specified in section 3.1.1.2 of this appendix. If the
conventional oven is capable of operating in inactive mode, as defined
in section 1.12 of this appendix, measure the average inactive mode
power of the conventional oven, PIA, in watts as specified
in section 3.1.1.2.1 of this appendix. If the conventional oven is
capable of operating in off mode, as defined in section 1.14 of this
appendix, measure the average off mode power of the conventional oven,
POM, in watts as specified in section 3.1.1.2.2 of this
appendix.
3.2.1.5 Conventional oven cavity volume. Measure the oven cavity
volume, CVO, in cubic feet (L), as specified in section
3.1.1.3 of this appendix.
3.2.2 Conventional surface unit test energy consumption.
3.2.2.1 Conventional surface unit average test energy consumption.
For the surface unit under test, measure the energy consumption,
ECT, in watt-hours (kJ) of electricity or the volume of gas
consumption, VCT, in standard cubic feet (L) of gas and the
test block temperature, TCT, at the end of the 15 minute
(reduced input setting) test interval for the test specified in section
3.1.2 of this appendix and the total time, tCT, in hours,
that the unit is under test. Measure any electrical energy,
EIC, consumed by an ignition device of a gas heating element
or other electrical components required for the operation of the
conventional gas cooking top in watt-hours (kJ).
3.2.2.2 Conventional surface unit standby mode and off mode energy
consumption. Make measurements as specified in section 3.1.2.1 of this
appendix. If the conventional surface unit is capable of operating in
inactive mode, as defined in section 1.12 of this appendix, measure the
average inactive mode power of the conventional surface unit,
PIA, in watts as specified in section 3.1.2.1.1 of this
appendix. If the conventional surface unit is capable of operating in
off mode, as defined in section 1.14 of this appendix, measure the
average off mode power of the
[[Page 37967]]
conventional surface unit, POM, in watts as specified in
section 3.1.2.1.2 of this appendix.
3.2.3 Conventional range standby mode and off mode energy
consumption. Make measurements as specified in section 3.1.3 of this
appendix. If the conventional range is capable of operating in inactive
mode, as defined in section 1.13 of this appendix, measure the average
inactive mode power of the conventional range, PIA, in watts
as specified in section 3.1.3.1 of this appendix. If the conventional
range is capable of operating in off mode, as defined in section 1.14
of this appendix, measure the average off mode power of the
conventional range, POM, in watts as specified in section
3.1.3.2 of this appendix.
3.2.4 Microwave oven test standby mode and off mode power. Make
measurements as specified in Section 5, Paragraph 5.3 of IEC 62301
(Second Edition) (incorporated by reference; see Sec. 430.3). If the
microwave oven is capable of operating in standby mode, as defined in
section 1.18 of this appendix, measure the average standby mode power
of the microwave oven, PSB, in watts as specified in section
3.1.4.1 of this appendix. If the microwave oven is capable of operating
in off mode, as defined in section 1.14 of this appendix, measure the
average off mode power of the microwave oven, POM, as
specified in section 3.1.4.1.
3.3 Recorded values.
3.3.1 Record the test room temperature, TR, at the start
and end of each range, oven or cooktop test, as determined in section
2.5 of this appendix.
3.3.2 Record the measured test block, test block body, and test
block base weights W1, W2, and W3 in
pounds (kg).
3.3.3 Record the initial temperature, T1, of the test
block under test.
3.3.4 For a conventional oven with a thermostat which operates by
cycling on and off, record the conventional oven test measurements
TA, EA, TB, EB,
TC, EC, TD, and ED for
conventional electric ovens or TA, VA,
TB, VB, TC, VC,
TD, and VD for conventional gas ovens. If the
thermostat controls the oven temperature without cycling on and off,
