Energy Conservation Program: Test Procedures for Conventional
Cooking Products With Induction Heating Technology
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notice of proposed rulemaking; public meeting.
-----------------------------------------------------------------------
SUMMARY: The U.S. Department of Energy (DOE) proposes to revise its
test procedures for cooking products established under the Energy
Policy and Conservation Act. Test procedures for cooking products can
be found at DOE's regulations for Energy Conservation Program for
Consumer Products, subpart B, appendix I (Appendix I). The proposed
amendments to Appendix I would amend the test method for measuring the
energy efficiency of induction cooking tops and ranges. Appendix I does
not currently include any test methods applicable to induction cooking
products. The proposed amendments would incorporate induction cooking
tops by amending the definition of ``conventional cooking top'' to
include induction heating technology. Furthermore, the proposed
amendments would require for cooking tops the use of test equipment
compatible with induction technology as well as with gas burners and
electric resistance heating elements. Specifically, the amendments
would 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. Appendix
I currently specifies the test block size for electric cooking tops
based on the surface unit diameter; however, there are no provisions
for determining which test block size to use for non-circular electric
surface units. The proposed amendments include a clarification that the
test block size be determined using the smallest dimension of the
electric surface unit.

I. Authority and Background
Title III of the Energy Policy and Conservation Act (42 U.S.C.
6291, et seq.; ``EPCA'' or, ``the Act'') sets forth a variety of
provisions designed to improve energy efficiency. (All references to
EPCA refer to the statute as amended through the Energy Independence
and Security Act of 2007 (EISA 2007), Public Law 110-140 (Dec. 19,
2007)). Part B of title III, which for editorial reasons was
redesignated as Part A upon incorporation into the U.S. Code (42 U.S.C.
6291-6309), establishes the ``Energy Conservation Program for Consumer
Products Other Than Automobiles.'' These include residential kitchen
ranges and ovens, the subject of today's notice of proposed rulemaking
(NOPR). (42 U.S.C. 6292(a)(10))
Under EPCA, this program consists essentially of four parts: (1)
Testing, (2) labeling, (3) Federal energy conservation standards, and
(4) certification and enforcement procedures. The testing requirements
consist of test procedures that manufacturers of covered products must
use (1) as the basis for certifying to DOE that their products comply
with the applicable energy conservation standards adopted under EPCA,
and (2) for making representations about the efficiency of those
products. Similarly, DOE must use these test requirements to determine
whether the products comply with any relevant standards promulgated
under EPCA.
A. General Test Procedure Rulemaking Process
Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures
DOE must follow when prescribing or amending test procedures for
covered products. EPCA provides 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 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. . (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)) If DOE determines that the amended test procedure would
alter the measured efficiency of a covered product, DOE must amend the
applicable energy conservation standard accordingly. (42 U.S.C.
6293(e)(2))
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)
(Appendix I).
DOE established the test procedures in a final rule published in
the Federal Register on May 10, 1978. 43 FR 20108, 20120-28. These test
procedures did not cover induction cooking products because they were,
at the time, relatively new products, and represented a small share of
the market. 43 FR 20117. 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 did not address induction
cooking, but 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
[[Page 6234]]
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 only regulate
design requirements, nor is there an EnergyGuide \1\ labeling program
for cooking products.
---------------------------------------------------------------------------
\1\ For more information on the EnergyGuide labeling program,
see: www.access.gpo.gov/nara/cfr/waisidx_00/16cfr305_00.html.
---------------------------------------------------------------------------
DOE recently conducted a separate rulemaking to address standby and
off mode energy consumption, as well as certain active mode testing
provisions, for residential dishwashers, dehumidifiers, and
conventional cooking products. DOE published a final rule on October
31, 2012 (77 FR 65942, hereafter referred to as the October 2012 Final
Rule), adopting standby and off mode provisions that satisfy the EISA
2007 amendments to EPCA, which require DOE to 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))
II. Summary of the Notice of Proposed Rulemaking
In today's NOPR, DOE proposes amendments to the test procedures in
Appendix I that would allow for testing 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 on the cooking top.\2\ 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. Under the proposed amendments, which would amend the
definition of ``conventional cooking top'' to include products with
induction heating, induction cooking products would be tested according
to the same test procedures as conventional cooking products.
---------------------------------------------------------------------------
\2\ DOE is not aware of any residential conventional ovens that
use induction heating technology that are available on the market in
the United States.
---------------------------------------------------------------------------
The current test method for conventional cooking tops (which is
also used for the cooking top portion of conventional ranges) involves
heating a solid aluminum test block on each surface unit of the cooking
top. The cooking top cooking efficiency is determined by averaging the
efficiencies of all surface units on the cooking top. The proposed test
procedure would replace the aluminum test blocks currently specified
for conventional cooking top testing with hybrid test blocks comprising
two separate stacked pieces: a stainless steel alloy 430 base, which is
compatible with the induction technology, and an aluminum body. The
proposed hybrid test blocks would have the same outer diameters and
heat capacities as the existing aluminum test blocks.
DOE considered other potential test blocks, including blocks made
entirely of carbon steel alloy 1018, and hybrid blocks with carbon
steel bases, but found the results using those blocks to be less
repeatable than for the hybrid blocks with stainless steel alloy 430
bases. DOE also considered an alternate test method based on heating
water. While this method may better represent actual consumer use, DOE
is not proposing a water-heating test procedure due to concerns
regarding repeatability, and to maintain consistency with the existing
test procedure for conventional cooking tops and ranges.
In today's NOPR, DOE further proposes methodology to determine the
required test block size for all electric surface units, including
those that are non-circular.
III. Discussion
A. Products Covered by This Test Procedure Rulemaking
As discussed in section I of this NOPR, the test procedures
currently in Appendix I do not apply to induction cooking products.
Induction products were not considered in the initial final rule to
establish these test procedures because of their relatively small
market share in 1978. 43 FR 20117. Today's proposal would amend the DOE
test procedures for conventional cooking tops and ranges to cover
induction cooking products.
Although induction cooking products started as a niche product with
a very small market share, a recent survey of major retailers indicates
that roughly 10 percent of all cooking tops currently available on the
market now use induction heating. Additionally, the three manufacturers
comprising more than 84 percent of the market for conventional ranges
\3\ each offer multiple induction cooking products. Given the increased
availability of induction cooking products, DOE believes these products
now warrant inclusion in the Appendix I test procedures to allow for
consideration in future rulemaking analyses.

Appliance Industry: Market Share, Life Expectancy & Replacement
Market, and Saturation Levels''. Appliance Magazine Market Research
Report, January 2010.
---------------------------------------------------------------------------
Induction cooking products use an oscillating magnetic field,
produced by alternating current through a coil under the cooking top
surface, to generate (``induce'') current in the cooking vessel. The
current in turn creates heat in the cooking vessel due to the
electrical resistance of the metal, and the heat is transferred to the
food load by means of conduction and convection. In order for the
current to be induced and the induction technology to function
properly, the cooking vessel must be made of a ferromagnetic material,
such as steel or iron.
As discussed further in section III.C of this NOPR, the amendments
proposed in today's notice would apply to conventional cooking products
in general, including induction cooking products. DOE currently defines
``cooking products'' as the major household cooking appliances that
cook or heat food by gas, electricity, or microwave energy, and include
conventional ranges, conventional cooking tops, conventional ovens,
microwave ovens, microwave/conventional ranges and other cooking
products. 10 CFR 430.2. A ``conventional cooking top'' contains one or
more surface units which include either a gas flame or electric
resistance heating. Id. A ``conventional range'' consists of a
conventional cooking top and one or more conventional ovens. Id.
The current definition of ``conventional cooking top,'' and by
extension, the definition of ``conventional range,'' does not refer to
heating by means of electricity other than electric resistance heating,
which would preclude induction heating. Because of the increased
availability of induction cooking products discussed in the beginning
of this section, DOE is proposing to amend the definition of
``conventional cooking top'' to a household cooking appliance within a
class of kitchen ranges and ovens, each of which consists of a
horizontal surface containing one or more surface units that utilize a
gas flame, electric resistance heating, or electric inductive heating.
The definition of ``conventional range'' would remain unchanged, but
[[Page 6235]]
would newly cover products with a conventional oven and a cooking top
that heats by means of induction technology.
Appendix I also includes a definition of ``active mode,'' which
references production of heat by means of a gas flame, electric
resistance heating, or microwave energy. 10 CFR part 430, subpart B,
appendix I. As with the definition of ``conventional cooking top,''
this definition does not cover induction cooking products. DOE proposes
to revise the definition of ``active mode'' to a mode in which a
conventional cooking top, conventional oven, conventional range, or
microwave oven is connected to a mains power source, has been
activated, and is performing the main function of producing heat by
means of a gas flame, electric resistance heating, electric inductive
heating, or microwave energy. The definition would include the current
clarification that delay start mode is a one-off user-initiated short
duration function that is associated with an active mode. This
definition would be consistent with the proposed definition of
``conventional cooking top.''
DOE requests comment on the proposed amended definitions of
conventional cooking top and active mode.
B. Effective Date
The amended test procedure would become effective 30 days after any
test procedure final rule is published in the Federal Register. The
amendments would require that as of 180 days after publication of any
test procedure final rule, representations related to the energy
consumption of conventional cooking products, including induction
cooking products, must be based upon results generated under the
applicable provisions of the amended test procedures in Appendix I. (42
U.S.C. 6293(c)(2))
C. Active Mode Test Procedure
The current test procedure for conventional cooking tops involves
heating an aluminum test block on each surface unit of the cooking top.
Two aluminum test blocks, of different diameters, are specified for
testing different surface units. The small test block (6.25 inches
diameter) is used for electric surface units with diameters of 7 inches
or less, and the large test block (9 inches diameter) is used for
electric surface units with diameters greater than 7 inches and all gas
surface units. Once the initial test and ambient conditions are met,
the surface unit is turned to its maximum energy input setting. After
the test block temperature increases by 144 [deg]F, the surface unit is
immediately reduced to 25 percent 5 percent of the maximum
energy input rate for 15 0.1 minutes. The efficiency of
the surface unit is calculated as the ratio of the energy transferred
to the test block (based on its temperature rise) to the energy
consumed by the cooking top during the test. The cooking top cooking
efficiency is calculated as the average efficiency of the surface units
on the cooking top.
As discussed in section III.A of today's NOPR, induction cooking
products are only compatible with ferromagnetic cooking vessels because
their high magnetic permeability concentrates the induced current near
the surface of the metal, increasing resistance and thus heating.
Aluminum is not a ferromagnetic metal--its lower magnetic permeability
allows the magnetic field to penetrate further into the material so
that the induced current flows with little resistance, and thus does
not heat up when it encounters an oscillating magnetic field.
Therefore, the aluminum test blocks, currently required by Appendix I,
are not appropriate for testing induction cooking products.
DOE conducted testing to investigate potential substitute test
blocks for testing induction cooking products. DOE conducted tests on
three conventional and three induction cooking tops to determine what
effects, if any, the different types of test blocks would have on the
test-to-test repeatability and final efficiency results. The test
sample included conventional cooking tops to allow for a comparison
between the substitute test blocks and the current aluminum test
blocks.
DOE considered three possible substitute test blocks: carbon steel,
carbon steel hybrid, and stainless steel hybrid. Table III.1 describes
the construction of the current aluminum test blocks and the three
substitute test blocks.
Table III.1--Test Block Composition Descriptions
------------------------------------------------------------------------
Test block composition
Test block classification (component and material)
------------------------------------------------------------------------
Aluminum............................... One solid aluminum alloy 6061
block.
Carbon Steel........................... One solid carbon steel alloy
1018 block.
Carbon Steel Hybrid.................... Carbon steel alloy 1018 base +
Aluminum alloy 6061 body.
Stainless Steel Hybrid................. Stainless steel alloy 430 base
+ Aluminum alloy 6061 body.
------------------------------------------------------------------------
The diameters and heat capacities of the aluminum test blocks
currently specified in Appendix I reflect consumer cooking behavior.
DOE is not aware of information indicating cooking behavior has
changed. Therefore, each substitute test block was constructed with the
same diameter as the current aluminum test blocks (6.25 inches for
small and 9 inches for large). Additionally, DOE varied the heights of
the substitute test blocks to match the heat capacities of the current
aluminum blocks. For the hybrid test blocks, DOE set the thickness of
the steel bases at 0.25 inches to be thin enough to represent the
thickness of a typical pot or pan while still being thick enough to
prevent warping. DOE set the height of the aluminum body in the hybrid
test blocks so the overall heat capacity (the sum of the steel base
heat capacity and the aluminum body heat capacity) matched that of the
current aluminum test blocks.
DOE proposes in today's NOPR to maintain the test method of heating
the test blocks, but to substitute the current aluminum test blocks
with the stainless steel hybrid test blocks described above for testing
all cooking tops covered by the proposed definition of conventional
cooking top (i.e., gas flame, electric resistance heating, and electric
inductive heating). Sections III.C.1 through III.C.4 below compare the
test results for the different potential test blocks and discuss the
rationale for selecting the stainless steel hybrid test block as the
substitute.
DOE also conducted tests to heat water in cooking vessels to
compare test repeatability with the metal block heating tests. Heating
water would allow for a test procedure that is more representative of
actual consumer usage (in terms of the cooking food load), but would
also introduce additional sources
[[Page 6236]]
of variability. Section III.C.5 below describes the water-heating
tests.
1. Aluminum Test Blocks
DOE conducted tests using the current aluminum test blocks to
establish a baseline for comparison to the candidate substitute test
blocks. Appendix I provides specifications for the large and small
aluminum test blocks as shown in Table III.2.

Small.............................. 6.25 0.05 2.8................... 8.5 0.1. 0.23................. 1.96
Large.............................. 9 0.05... 3..................... 19 0.1.. 0.23................. 4.37
--------------------------------------------------------------------------------------------------------------------------------------------------------
Because aluminum is not compatible with induction cooking, DOE only
tested the aluminum blocks on the three conventional cooking tops (2
electric and 1 gas cooking tops), in the test sample. The small test
block was used for electric surface units with diameters of 7 inches or
less. The large test block was used for electric surface units with
diameters greater than 7 inches and all gas surface units, as required
by Appendix I.
DOE did not test every surface unit on each cooking top in the test
sample because most cooking tops include multiple surface units of
equal diameter and power rating. Prior investigative testing showed
that surface units with equal diameters and power ratings on the same
cooking top have similar performance. In these cases, DOE tested only
one of the identical surface units to limit the total number of tests.
Cooking Top A has electric resistance heating in open coils,
Cooking Top B has electric resistance heating under a smooth ceramic
surface, and Cooking Top C has gas-flame burners. Table III.3
summarizes the test results using the aluminum blocks for surface units
on these products. The surface unit numbers included in Table III.3 are
used to differentiate between surface units on the same cooking top.
The values listed for each surface unit summarize the data from five
tests, except where noted.

\a\ Values describe data for four tests, not five. In addition, cooking efficiencies for gas burners are
typically lower than for electric resistance heating elements.
\b\ Results lower than expected due to a meter error, but consistently low from test-to-test.
As shown in Table III.3, a set of five tests using the aluminum
test block on the surface units with electric resistance or gas flame
heating produced standard deviations of less than 3 percent for each
surface unit. These standard deviations correspond to 95-percent
confidence intervals within 4 percent of the mean efficiency.
DOE is aware that the mean efficiency listed for the gas surface
unit is lower than expected. Typically, gas surface units have
efficiencies at or above 40 percent. The lower-than-expected efficiency
suggests the magnitudes of the gas consumption for these tests as
measured by the meter are likely higher than the actual consumption.
The surface unit tested on Cooking Top C has a maximum energy output
rating of 9,200 Btu per hour. However, the measured gas use for each
test was consistently about 55 percent greater than the maximum rating
at the maximum energy input rate setting, suggesting the meter
overstated the gas consumption.
Although the meter readings affected the magnitude of the gas
surface unit efficiency results, DOE believes the results still provide
meaningful information for assessing the candidate test blocks. The
purpose of the testing was to compare the testing results, in terms of
repeatability and overall efficiency, across the different test block
types, and not necessarily to compare efficiencies from unit-to-unit.
DOE observed the same low efficiencies and high gas consumptions in the
tests on the substitute test blocks described in sections III.C.2
though III.C.5 of this NOPR, so the results for the gas cooking top can
still be compared between the different test blocks. The high meter
readings do not allow a consistent comparison of the gas surface unit
efficiency to the electric surface units, but gas surface units
typically have efficiencies in a lower range compared to electric
surface units.
2. Carbon Steel Test Blocks
DOE conducted tests using solid carbon steel test blocks with the
specifications shown in Table III.4, matching the aluminum test blocks
in diameter and heat capacity.

--------------------------------------------------------------------------------------------------------------------------------------------------------
DOE tested the carbon steel blocks on all six cooking tops in the
test sample, comprising the three conventional cooking tops discussed
in section III.C.1 and three induction cooking tops. Cooking Tops D and
E are built-in induction cooking tops, and Cooking Top F is a portable,
single-element induction cooking top. Table III.5 summarizes the test
results using the carbon steel test blocks for surface units on these
products. As described in section III.C.1, DOE did not test multiple
surface units with equal diameters on the same cooking top, and the
surface unit numbers included in the table are used to differentiate
between surface units on the same cooking top.

The results in Table III.5 for carbon steel test blocks are
comparable to the test results for the aluminum test blocks presented
in Table III.3. The mean efficiencies for the carbon steel blocks were
slightly lower than the aluminum test blocks on each surface unit for
the conventional cooking tops (Cooking Tops A, B, and C), but the means
of the two test block types still fell within the 95-percent confidence
intervals for each surface unit. The carbon steel blocks produced
results that were just as repeatable as the aluminum test blocks, with
standard deviations less than 3 percent for all surface units, and 95-
percent confidence intervals all within 4 percent of the mean
efficiency.
Based on these test results, DOE concludes that the carbon steel
test blocks are a reasonable substitute for the aluminum test blocks.
However, the heating that occurs using a solid block of ferromagnetic
material may not be representative of how induction cooking tops
actually operate in real-world situations. Typically, induction cooking
tops only induce current in a thin layer of ferromagnetic material in
the cooking vessel, which then heats up the food load. For this reason,
DOE conducted further investigations with hybrid test blocks, as
discussed below.
3. Carbon Steel Hybrid Test Blocks
DOE conducted additional tests using hybrid test blocks to more
closely reflect the real-world operation of induction cooking tops. DOE
fabricated carbon steel hybrid test blocks using a 0.25 inch base of
carbon steel 1018 with a body of aluminum 6061. Typical cookware is
slightly thinner gauge than this base, but DOE chose the base to
preclude against warping while the block heats up. Additionally, DOE
observed that the portable induction unit is packaged with a steel
plate adaptor of roughly the same thickness as DOE's carbon steel base
to allow for cooking with non-ferromagnetic cookware.
Table III.6 provides the component and overall properties of the
carbon steel hybrid test blocks. DOE varied the height of the aluminum
bodies so the overall heat capacities of the hybrid blocks would match
the solid aluminum test blocks described in section III.C.1.

DOE tested the carbon steel hybrid test blocks on all six cooking
tops in the test sample. Table III.7 summarizes the test results using
the carbon steel hybrid test blocks for surface units on these
products. As described in section III.C.1, DOE did not test multiple
surface units with equal diameters on the same cooking top, and the
surface unit numbers included in the table are used to differentiate
between surface units on the same cooking top.

\a\ Values describe data for four tests, not five. In addition, cooking efficiencies for gas burners are
typically lower than for electric resistance heating elements.
\b\ Results lower than expected due to a meter error, but consistently low from test-to-test.
The carbon steel hybrid test block results in Table III.7 are
similar to both the aluminum and carbon steel test block results
presented in Table III.3 and Table III.5. The efficiencies for the
conventional cooking tops are slightly lower than with the aluminum
test blocks, and also slightly lower than with the carbon steel test
blocks, but within the 95-percent confidence intervals. However, it is
not clear what effect the hybrid blocks have on the efficiencies for
the induction cooking tops. Five of the six induction surface units
have efficiencies nearly equal to or slightly higher than with the
single carbon steel test blocks. However, the efficiency for surface
unit on Cooking Top F dropped by more than 7 percent.
In addition, after conducting multiple tests using the carbon steel
hybrid test blocks, DOE observed rust forming on the carbon steel base.
DOE was concerned that the rust could lead to inconsistent heat
transfer between the carbon steel base and the aluminum body based on
the amount of rust present, which would affect thermal contact.\4\
Thus, DOE conducted another set of tests using hybrid test blocks with
stainless steel 430 bases that would be more resistant to rust
formation.
---------------------------------------------------------------------------
\4\ Rust also formed on the solid carbon steel test blocks,
which could affect heat transfer and repeatability. These issues
would likely be more significant for the carbon steel hybrid test
blocks due to the additional heat transfer surface between the base
and the test block.
---------------------------------------------------------------------------
4.Stainless Steel Hybrid Test Blocks
The specific heats and densities of carbon steel and stainless
steel are similar, so bases with the same dimensions have similar heat
capacities. Therefore, the same aluminum test bodies were used for both
sets of hybrid block tests. Table III.8 describes the component and
overall properties of the stainless steel hybrid test blocks.

DOE tested the stainless steel hybrid test blocks on all six
cooking tops in the test sample. Table III.9 summarizes the test
results for surface units on these products using the stainless steel
hybrid test blocks. As described in section III.C.1, DOE did not test
multiple surface units with equal diameters on the same cooking top,
and the surface

unit numbers included in the table are used to differentiate between
surface units on the same cooking top.

The stainless steel hybrid test block efficiency results in Table
III.9 are on average 2.5 percentage points lower than those for the
carbon steel hybrid test blocks shown in Table III.7. However, the
standard deviations and 95-percent confidence intervals are less than
for the aluminum test blocks, the carbon steel test blocks, and the
carbon steel hybrid test blocks, as shown in Table III.10.

efficiencies for the carbon steel, carbon steel hybrid, and stainless steel hybrid blocks on these surface
units are 54.99 percent, 54.36 percent, and 51.70 percent respectively.
Because the stainless steel hybrid test blocks produce the most
repeatable results from test-to-test, DOE is proposing that these test
blocks be required for testing induction cooking tops. DOE is also
proposing to amend the existing cooking tops test procedure to
incorporate the stainless steel hybrid blocks for cooking tops with gas
flame or electric resistance heating. This would ensure consistency in
results among all products covered by the proposed definition of
conventional cooking tops. DOE notes that, although the efficiency
results using the stainless steel hybrid test blocks for the cooking
tops with gas flame or electric resistance heating are on average 4.3
percentage points lower than for the aluminum test blocks, the relative
efficiencies among the various surface units remain generally
unchanged.
DOE seeks comment on its proposal to require the use of stainless
steel hybrid test blocks for testing all cooking tops that would be
covered by the proposed definition of conventional cooking tops in an
amended cooking products test procedure, including the potential burden
associated with the requirement for such new test equipment.
5.Water-Heating Tests
To investigate additional test methods that may be representative
of actual consumer usage, DOE conducted a test series based on water
heating in place of metal block heating. Water provides a heating
medium that is more representative of actual consumer use, because many
foods cooked on a cooking top have a relatively high liquid content.
However, water heating introduces additional sources of variability not
present for metal block heating--the temperature distribution in the
water is not always uniform, the properties of the water can vary from
lab to lab, and the ambient conditions and cookware surface effects can
have a large impact on the water boiling and evaporating throughout the
test.
DOE is aware of a draft cooking products test method based on water
heating that is under development by the International Electrotechnical
Commission (IEC). A draft amendment to IEC Standard 60350-2 Edition 1.0
``Household electric cooking appliances--Part 2: Hobs--Method for
measuring performance'' (Draft IEC 60350 Amendment) specifies heating
the water to a certain temperature at the maximum energy input setting,
and then turning the unit to a lower energy input setting for an
extended simmering period.
The Draft IEC 60350 Amendment specifies the quantity of water to be
heated in a standardized cooking vessel whose size is based on the
diameter of the surface unit. For this analysis, DOE chose the two IEC-
specified cooking vessels with diameters closest to the diameters
specified for the aluminum test blocks (6.25 inches and 9 inches). The
cookware consists of a thin-walled stainless steel cylinder attached to
a flat
[[Page 6240]]
stainless steel 430 base plate. The test method also specifies an
aluminum lid with vent holes and a small center hole to fix the
thermocouple in the center of the pot. Table III.11 describes the IEC
cookware and the quantity of water used for DOE's testing.\5\
---------------------------------------------------------------------------
\5\ Section 7.1.Z2 of the Draft IEC 60350 Amendment, ``Cookware
and water amount'', specifies the general construction of the
cookware, and Table Z3, ``Sizes of standardized cookware and water
amounts'', specifies the dimensions of the cookware and quantity of
water based on the diameter or the surface unit under test.
Table III.11--IEC Cookware and Water Specifications
--------------------------------------------------------------------------------------------------------------------------------------------------------

Cookware size diameter (in) (in) (in) (in) (lbs)
--------------------------------------------------------------------------------------------------------------------------------------------------------
Small......................................................... 5.91 0.24 4.92 6.5 2.27
Large......................................................... 9.45 0.24 4.92 10.43 5.95
--------------------------------------------------------------------------------------------------------------------------------------------------------
The Draft IEC 60350 Amendment specifies testing at the maximum
energy input rate until a calculated turndown temperature is reached,
at which point the energy input rate is reduced to a setting that will
maintain the water temperature above 194 [deg]F (a simmering
temperature), but as close to 194 [deg]F as possible without additional
adjustment of the low-power setting. The test ends 20 minutes after the
temperature increases above 194 [deg]F. The turndown temperature is
calculated based on an initial test to determine the number of degrees
that the temperature continues to rise after turning the unit off from
the maximum energy input setting. Energy consumption is measured
throughout the entire test, and the final metric describes the energy
in Watt-hours (Wh) per 1000 grams (g) of water necessary to reach and
maintain the simmering temperature.
DOE observed during some tests that the water approached boiling
even at 194 [deg]F, and a significant amount of the water evaporated or
boiled off for all of the tests. Additionally, the simmering water
temperatures varied from test-to-test even at the same reduced setting.
The test method only requires that the simmering temperature stay above
194 [deg]F for a valid test. Certain tests would produce simmering
temperatures around 196 [deg]F, close to the 194[emsp14][deg]F goal,
while others would rise above 200 [deg]F at the same setting. Both
tests would be deemed valid under the method in the Draft IEC 60350
Amendment method, but the normalized energy use results would vary
because the 200 [deg]F test would use significantly more energy.
To address this concern, DOE developed additional calculations to
estimate the efficiency of the water-heating process. The calculations
factor in the total temperature rise of the water to account for
differences in simmering temperatures, and the total amount of water
lost to boiling or evaporation during the test. DOE's method entails
measuring the mass of the cookware plus water at the start and end of
the test. Table III.12 shows the water-heating efficiency results using
the DOE calculation method.

Even after considering differences in the final water temperature
and the amount of water boiled or evaporated during the test, the
variability for the water-heating tests was still greater than for the
metal block tests. Table III.13 compares the standard deviations for
each surface unit tested with both the water-heating and metal block-
heating tests.

\a\ Values describe data for four tests, not five.
The water-heating test variability could potentially be reduced by
more stringent tolerances on the ambient conditions. Ambient air
pressure, temperature, and humidity significantly impact the amount of
water that evaporates during the test and the temperature at which the
water begins to boil. Appendix I, however, only specifies ambient air
temperature, and its relatively large tolerance, 77 [deg]F
9 [deg]F, could contribute to increased test variability.
Because the water-heating tests do not show an improvement in
repeatability from test-to-test under the current DOE test conditions
compared to the metal block tests, and because achieving closer ambient
temperature tolerances would potentially place a high burden on
manufacturers, DOE is proposing to use stainless steel hybrid test
blocks in the test procedure for all products covered under the
proposed definition of conventional cooking tops.
DOE acknowledges that the water-heating tests may better reflect
actual consumer behavior for cooking tops, and invites comment on
whether water-heating tests should be considered in place of the metal
block-heating tests. DOE also invites comment on the appropriate test
method and conditions for water-heating tests, and the burden that
would be incurred by more stringent specifications for ambient
conditions.
6. Non-Circular Electric Surface Units
As discussed in the beginning of section III.C, the small test
block (6.25 inches diameter) is used for testing surface units with
diameters of 7 inches or less, and the large test block (9 inches
diameter) is used for electric surface units with diameters greater
than 7 inches and all gas surface units. These provisions do not
address how to determine the proper test block size for testing non-
circular electric surface units.
DOE is aware that the Draft IEC 60350 Amendment requires measuring
the dimensions of each side of rectangular or similar electric surface
units, and by measuring the major and minor dimensions of elliptical or
similar electric surface units. For these types of surface units, the
smallest dimension is used to determine the cookware size according to
the Draft IEC 60350 Amendment.
DOE lacks information on the size of the cookware consumers
typically use for non-circular surface units. Given this lack of
consumer use data, and given the potential non-representative thermal
behavior of a test block in which a portion of the bottom is not
exposed to the surface unit, DOE proposes to amend section 3.2.1 of
Appendix I to replace the reference to an electric surface unit's
diameter with the electric surface unit's smallest dimension to account
for surface units of all shapes. This is consistent with the method
included in the Draft IEC 60350 Amendment. DOE does not propose to
change the requirement that all gas surface units be tested using the
large test block.
DOE invites comments on whether using the smallest dimension of an
electric surface unit is appropriate for determining the proper test
block size.
D. Standby and Off Mode Test Procedure
EISA 2007 amended EPCA to require that DOE amend its test
procedures for all covered residential products, including cooking
products, to include measures of standby mode and off mode energy
consumption, if technically feasible. (42 U.S.C. 6295(gg)(2)(A))
Accordingly, DOE recently conducted a separate rulemaking for
conventional cooking products, dishwashers, and dehumidifiers to
address standby and off mode energy consumption.\6\ 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.
---------------------------------------------------------------------------
\6\ DOE pursued amendments to Appendix I addressing standby and
off mode energy for microwave ovens as part of a separate
rulemaking. The most recent notice for this rulemaking is the SNOPR
published on May 16, 2012. 76 FR 72322.
---------------------------------------------------------------------------
Today's NOPR proposes a change to the definition of ``conventional
cooking top'' to include induction technologies. Under this proposed
definition, induction cooking tops would be covered by the standby and
off mode test procedures adopted in the separate test procedure
rulemaking.
DOE did not observe any standby mode or off mode operation or
features unique to induction cooking tops that would warrant any
changes to the standby mode and off mode test methods adopted by the
October 2012 Final Rule for conventional cooking tops. DOE invites
comment on whether induction cooking products require separate
consideration for standby mode and off mode testing.
E. Compliance With Other EPCA Requirements
EPCA requires that any new or amended test procedures for
residential products must be reasonably designed to produce test
results which measure energy efficiency, energy use, or
[[Page 6242]]
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))
DOE tentatively concludes that the amended test procedures would
produce test results that measure the energy consumption of cooking
tops during representative use, and that the test procedures would not
be unduly burdensome to conduct.
The test procedure proposed in today's NOPR follows the same method
currently included in Appendix I for testing cooking tops, but would
replace the aluminum test blocks with stainless steel hybrid blocks.
DOE estimates current testing represents a cost of roughly $500 per
test for labor, with a one-time investment of $2,000 for test equipment
($1,000 for test blocks and $1,000 for instrumentation). The proposed
reusable test blocks would represent an additional one-time expense of
approximately $500 for each test block, or $1000 for each pair of large
and small diameter test blocks. No additional instrumentation would be
required beyond what is required in the current test procedure. DOE
does not believe this additional cost represents an excessive burden
for test labs or manufacturers given the significant investments
necessary to manufacture, test and market consumer appliances, as
described further in section IV.B below. The only additional time
burden associated with the proposed test method is the time required to
weigh the stainless steel base in addition to the aluminum body. This
additional step in the test procedure would increase the test duration
by about 2 minutes per surface unit.
DOE concluded in the test procedure rulemaking for cooking products
preceding today's NOPR, completed recently by the publication of the
October 2012 Final Rule (see section I.B. for the rulemaking history
for today's NOPR), that the amended test procedure is not unduly
burdensome to conduct. In today's NOPR, DOE further concludes, given
the small magnitude of the proposed changes (both in terms of the new
test blocks and the time needed to take the test), that the newly
proposed amended test procedure for cooking products would not be
unreasonably burdensome to conduct.
IV. Procedural Issues and Regulatory Review
A. Review Under Executive Order 12866
The Office of Management and Budget has determined that test
procedure rulemakings do not constitute ``significant regulatory
actions'' under section 3(f) of Executive Order 12866, Regulatory
Planning and Review, 58 FR 51735 (Oct. 4, 1993). Accordingly, this
action was not subject to review under the Executive Order by the
Office of Information and Regulatory Affairs (OIRA) in the Office of
Management and Budget (OMB).
B. Review Under the Regulatory Flexibility Act
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires
preparation of a regulatory flexibility analysis (RFA) 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: http://energy.gov/gc/office-general-counsel.
DOE reviewed today's proposed rule under the provisions of the
Regulatory Flexibility Act and the procedures and policies published on
February 19, 2003. The proposed rule would amend the test method for
measuring the energy efficiency of conventional cooking tops and ranges
to include test methods applicable to induction cooking products.
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 cooking products.
Most of the manufacturers supplying conventional cooking products
are large multinational corporations. DOE surveyed the AHAM member
directory to identify manufacturers of residential 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.
For the reasons stated in the preamble, DOE has tentatively
concluded that the proposed rule would not have a significant impact on
either small or large manufacturers under the applicable provisions of
the Regulatory Flexibility Act. The proposed rule would amend DOE's
test procedures for cooking products by incorporating testing
provisions to address active mode energy consumption for induction
cooking products that will be used to develop and test compliance with
any future energy conservation standards that may be established by
DOE. The test procedure amendments involve the measurement of active
mode energy consumption through the use of a different metal test block
than is currently specified for conventional cooking tops. The proposed
amendments would also apply for testing products currently considered
conventional cooking tops. DOE estimates a cost for this new equipment
of approximately $1000. Additionally, DOE estimates a cost of roughly
$6,000 for manufacturers to test induction cooking products not
currently covered by the test procedure. This estimate assumes $500 per
test, as described in section III.E, with up to 12 total tests needed
assuming three induction cooking top models with four individual tests
per cooking top model. This cost is small compared to the average
annual revenue of the two identified small businesses, which DOE
estimates to be over $40 million.\7\ These tests follow the same
methodology and can be conducted in the same facilities used for the
current energy testing of conventional cooking tops, so there would be
no additional facilities costs required by the proposed rule.
---------------------------------------------------------------------------
\7\ Estimated average revenue is based on financial information
provided for the two small businesses in reports provided by Dun and
Bradstreet.
---------------------------------------------------------------------------
For these reasons, DOE tentatively concludes and certifies that the
proposed rule would not have a significant economic impact on a
substantial number of small entities. Accordingly, DOE has not prepared
a
[[Page 6243]]
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).
C. Review Under the Paperwork Reduction Act of 1995
Manufacturers of conventional cooking products must certify to DOE
that their products comply with any applicable energy conservation
standards. In certifying compliance, manufacturers must test their
products according to the DOE test procedures for conventional cooking
products, including any amendments adopted for those test procedures.
DOE has established regulations for the certification and recordkeeping
requirements for all covered consumer products and commercial
equipment, including conventional cooking products. (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. Public reporting
burden for the certification is estimated to average 20 hours per
response, including the time for reviewing instructions, searching
existing data sources, gathering and maintaining the data needed, and
completing and reviewing the collection of information.
There is currently no information collection requirement related
specifically to induction cooking tops. In the event that DOE proposes
an energy conservation standard with which manufacturers must
demonstrate compliance, or otherwise proposes to require the collection
of information derived from the testing of induction cooking tops
according to this test procedure, DOE will seek OMB approval of such
information collection requirement. DOE will seek approval either
through a proposed amendment to the information collection requirement
approved under OMB control number 1910-1400 or as a separate proposed
information collection requirement.
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 proposed rule, DOE proposes test procedure amendments that
it expects will be used to develop and implement future energy
conservation standards for conventional cooking products. DOE has
determined that this rule falls into a class of actions that are
categorically excluded from review under the National Environmental
Policy Act of 1969 (42 U.S.C. 4321 et seq.) and DOE's implementing
regulations at 10 CFR part 1021. Specifically, this proposed rule would
amend the existing test procedures without affecting the amount,
quality or distribution of energy usage, and, therefore, would 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 has examined this proposed rule and has
determined that it would not have a substantial direct effect on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government. EPCA governs and prescribes Federal
preemption of State regulations as to energy conservation for the
products that are the subject of today's proposed 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,
the proposed 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. Pub. L. 104-4, sec. 201 (codified at 2 U.S.C. 1531).
For a proposed regulatory action likely to result 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
[[Page 6244]]
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 today's
proposed 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 rule would 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 would not
result in any takings that might require compensation under the Fifth
Amendment to the U.S. Constitution.
J. Review Under Treasury and General Government Appropriations Act,
2001
Section 515 of the Treasury and General Government Appropriations
Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most
disseminations of information to the public under guidelines
established by each agency pursuant to general guidelines issued by
OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 2002), and
DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has
reviewed today's proposed 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 proposed 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 proposed significant energy action,
the agency must give a detailed statement of any adverse effects on
energy supply, distribution, or use should the proposal be implemented,
and of reasonable alternatives to the action and their expected
benefits on energy supply, distribution, and use.
Today's regulatory action to amend the test procedure for measuring
the energy efficiency of conventional cooking products is not a
significant regulatory action under Executive Order 12866. Moreover, it
would not have a significant adverse effect on the supply,
distribution, or use of energy, nor has it been designated as a
significant energy action by the Administrator of OIRA. Therefore, it
is not a significant energy action, and, accordingly, DOE has not
prepared a Statement of Energy Effects.
L. Review Under Section 32 of the Federal Energy Administration Act of
1974
Under section 301 of the Department of Energy Organization Act
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the
Federal Energy Administration Act of 1974, as amended by the Federal
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA)
Section 32 essentially provides in relevant part that, where a proposed
rule authorizes or requires use of commercial standards, the notice of
proposed rulemaking must inform the public of the use and background of
such standards. In addition, section 32(c) requires DOE to consult with
the Attorney General and the Chairman of the Federal Trade Commission
(FTC) concerning the impact of the commercial or industry standards on
competition. The amendments proposed in today's NOPR do not authorize
or require the use of any commercial standards.

E. Issues on Which DOE Seeks Comment
Although DOE welcomes comments on any aspect of this proposal, DOE
is particularly interested in receiving comments and views of
interested parties concerning the following issues:
1. Proposed Amended Definitions
DOE requests comment on the proposed amended definitions of
``conventional cooking top'' and ``active mode.'' (See section III.A)
2. Stainless Steel Hybrid Test Blocks
DOE seeks comment on its proposal to require the use of stainless
steel hybrid test blocks for testing all cooking tops that would be
covered by the proposed definition of conventional cooking tops in an
amended cooking products test procedure, including the potential burden
associated with the requirement for such new test equipment. (See
section III.C.4)
3. Water-Heating Test
DOE invites comment on whether water-heating tests should be
considered in place of the metal block-heating tests, and on the
appropriate water-heating test method and conditions. DOE also invites
comment on the burden that would be incurred by more stringent
specifications for ambient conditions. (See section III.C.5)
4. Non-Circular Electric Surface Units
DOE invites comments on whether using the smallest dimension of an
electric surface unit is appropriate for determining the proper test
block size. (See section III.C.6)
5. Standby and Off Mode
DOE requests comment on whether induction cooking products include
any unique features or operational modes that would not be covered by
the definitions and standby and off mode test procedures included in
the October 2012 Final Rule. 77 FR 65942. (See section III.D)
VI. Approval of the Office of the Secretary
The Secretary of Energy has approved publication of this proposed
rule.

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 function of producing heat by means of a gas flame, electric
resistance heating, electric inductive 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.
