I. Authority and Background 

Title III, Part B1 of the Energy Policy 

and Conservation Act of 1975 (EPCA or 

the Act), Public Law 94–163 (42 U.S.C. 

6291–6309, as codified) sets forth a 

variety of provisions designed to 

improve energy efficiency and 

established the Energy Conservation 

Program for Consumer Products Other 

Than Automobiles, a program covering 

most major household appliances.2

These include residential dishwashers 

and conventional cooking products,3 the 

subject of today’s notice. (42 U.S.C. 

6292(a)(6) and (10); 6295(cc)) 

Under the Act, this program consists 

essentially of four parts: (1) Testing, (2) 

labeling, (3) establishing Federal energy 

conservation standards, and (4) 

certification and enforcement 

procedures. The testing requirements 

consist of test procedures that 

manufacturers of covered products must 

use: (1) As the basis for certifying to 

DOE that their products comply with 

applicable energy conservation 

standards adopted pursuant to EPCA, 

and (2) for making representations about 

the efficiency of those products. (42 

U.S.C. 6293(c); 6295(s)) Similarly, DOE 

must use these test procedures in any 

enforcement action to determine 

whether the products comply with these 

energy conservation standards. (42 

U.S.C. 6295(s))

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 test 

procedures be reasonably designed to 

produce test results which measure 

energy efficiency, energy use, or 

estimated annual operating cost of a 

covered product during a representative 

average use cycle or period of use, as 

determined by the Secretary of Energy, 

and not 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)) 

DOE’s test procedure for dishwashers 

is found in the Code of Federal 

Regulations (CFR) at 10 CFR part 430, 

subpart B, appendix C. DOE’s test 

procedures for conventional ranges, 

cooktops, and ovens (including 

microwave ovens, which are considered 

separately from the conventional 

cooking products covered in today’s 

rule) are found at 10 CFR part 430, 

subpart B, appendix I. For background 

on the establishment of the first DOE 

test procedures for dishwashers and 

conventional cooking products, 

subsequent amendments to those 

procedures, and the rulemaking history 

for today’s supplemental notice of 

proposed rulemaking (SNOPR), please 

see the SNOPR issued on May 25, 2012. 

(77 FR 31444) (May 2012 SNOPR). In 

today’s SNOPR, DOE considers 

comments received on the dishwasher 

test procedure in response to the May 

2012 SNOPR and during a public 

meeting held June 1, 2012 (June 2012 

Public Meeting). DOE will provide 

further response to comments received 

on the May 2012 SNOPR, as 

appropriate, in any final rule to 

establish amended test procedures. 

II. Discussion 

A. Proposals 

Obsolete Dishware and Food Items 

In the May 2012 SNOPR, DOE 

proposed to update obsolete flatware 

and detergent specifications. DOE has 

determined that certain additional 

flatware, dishware, and food items used 

in the test procedure are also obsolete, 

or has received comments in this test 

procedure rulemaking indicating that 

the items may be obsolete. These items 

include: The cup and saucer, the bread 

and butter plate, the fruit bowl, the 

dinner fork, the salad fork, the teaspoon, 

the knife, the margarine, and the coffee. 

In today’s SNOPR, DOE proposes to use 

the items listed in Table I in place of the 

obsolete or potentially obsolete items. 

DOE further proposes that use of these 

items be required 30 days after 

publication of any final amended test 

procedures and seeks comment on 

whether the specified items can be 

procured in 30 days.

Definition of Normal Cycle 

In the May 2012 SNOPR, DOE stated 

that the current DOE dishwasher test 

procedure defines the normal cycle as 

‘‘the cycle type recommended by the 

manufacturer for completely washing a 

full load of normally soiled dishes 

including the power-dry feature.’’ 

(Section 1.6 of 10 CFR part 430, subpart 

B, appendix C) DOE noted that it is 

aware that certain dishwashers have 

multiple wash and/or drying 

temperature options for the cycle setting 

required under the normal cycle 

definition. For these dishwashers, DOE 

proposed to clarify in the definition that 

the normal cycle shall include the wash 

and drying temperature options 

recommended by the manufacturer for 

completely washing a full load of 

normally soiled dishes including the 

power-dry feature. DOE sought 

comment on the wash and drying 

temperature options to be selected in 

the case that the cycle setting required 

under the normal cycle definition has 

multiple wash and/or drying 

temperature options but the 

manufacturer does not provide such a 

recommendation. 

In response to the May 2012 SNOPR, 

commenters suggested that in the 

absence of a manufacturer 

recommendation concerning 

temperature options for the normal 

cycle, the highest energy consumption 

temperature options should be selected. 

This approach is consistent with the 

approach taken in DOE’s recent 

rulemaking to amend the test procedure 

for residential clothes washers (77 FR 

13888, Mar. 7, 2012). In that 

rulemaking, DOE amended part (B) of 

the definition of energy test cycle to 

state that where multiple alternative 

selections offer a wash/rinse 

temperature selection for which a 

temperature use factor has been 

developed and that is not available on 

the cycle recommended by the 

manufacturer for washing cotton or 

linen clothes described in part (A) of the 

energy test cycle definition, the 

alternate cycle selection with the 

highest energy consumption for that 

TUF must be included in the energy test 

cycle. For consistency with the 

approach taken in the clothes washer 

test procedure rulemaking, and to 

ensure that the test procedure does not

49066 Federal Register / Vol. 77, No. 158 / Wednesday, August 15, 2012 / Proposed Rules 

under-estimate the energy use of the 

dishwasher, DOE proposes in today’s 

SNOPR that in the definition of normal 

cycle, in the absence of a manufacturer 

recommendation on temperature 

options, the highest energy 

consumption temperature options for 

washing and drying must be selected. 

Ambient Temperature 

DOE proposed in the May 2012 

SNOPR to maintain the current room 

ambient air temperature requirement of 

75 degrees Fahrenheit (°F) ±5 °F, while 

allowing greater tolerance on the room 

air temperature during standby mode 

and off mode testing in accordance with 

provisions incorporated by reference 

from the International Electrotechnical 

Commission (IEC) Standard 62301, 

‘‘Household electrical appliances— 

Measurement of standby power’’, 

Edition 2.0 2011–01 (IEC Standard 

62301). DOE received comments that 

the more stringent active mode ambient 

temperature conditions should apply to 

all testing, including standby mode and 

active mode testing performed 

separately from active mode testing to 

ensure accurate, repeatable, and 

reproducible results. Commenters also 

stated that the test procedure should 

clarify that the tolerances specified 

indicate the allowable limits of variation 

in temperature, but do not permit the 

deliberate variation with those limits. 

Commenters also suggested that DOE 

tighten the tolerance on the ambient 

temperature to ± 2 °F, because a 1 °F 

ambient temperature change can result 

in a 1.5 kilowatt-hour (kWh) change in 

estimated annual energy use (EAEU), 

although the commenters acknowledged 

that this tighter tolerance could be 

burdensome for certain manufacturers 

or laboratories. 

In specifying tolerances in its test 

procedures, DOE provides a range of 

temperatures under which the test 

results are considered valid, regardless 

of the reasons for why a particular 

temperature within the range was 

selected or achieved. Therefore, DOE is 

not proposing to state that the test 

should be conducted at the nominal 

center of the ambient temperature range. 

DOE recognizes the impact of ambient 

temperature on the active mode 

measurement, however, and as an 

alternative to the ±5 °F tolerance 

previously proposed, DOE proposes to 

tighten the tolerance to ±2 °F. DOE seeks 

comment on the capabilities of test 

laboratories to maintain this tolerance 

and the burden associated with it. DOE 

is not proposing in today’s SNOPR to 

require that standby mode and off mode 

testing be conducted under the same 

ambient temperature as active mode 

testing because no data are available to 

suggest that the standby mode and off 

mode power of residential dishwashers 

varies significantly within the allowable 

ambient temperature range of IEC 

Standard 62301, and because this 

approach would increase the burden for 

those manufacturers or laboratories that 

choose to conduct standby mode and off 

mode testing separately from active 

mode testing. 

Preconditioning 

DOE proposed in the May 2012 

SNOPR to require that the 

preconditioning cycle for soil-sensing 

dishwashers be run using the cycle 

setting selected for active mode, and 

that the power supply to the unit be 

continuously maintained throughout 

testing, including after the 

preconditioning cycle and in between 

all energy test cycles, to maintain 

calibration of the turbidity sensor. 

Comments received from manufacturers 

indicated that certain dishwashers may 

be designed to self-calibrate in one 

cycle, but may sometimes require an 

additional cycle to perform this 

calibration. In addition, commenters 

noted that two preconditioning cycles 

would help to clean out residual dirt 

from the machine prior to sensor 

calibration and energy testing. DOE 

agrees that two preconditioning cycles 

would ensure a clean unit at the start of 

testing and proper sensor calibration in 

soil-sensing dishwashers that may, 

under certain conditions, not selfcalibrate in one cycle. Therefore, in 

today’s SNOPR, DOE proposes two 

preconditioning cycles, clarifying that 

the second preconditioning cycle is to 

be used to determine detergent dosing. 

DOE seeks comment on the burden 

associated with requiring an additional 

preconditioning cycle. 

Updated Industry Test Method 

In the May 2012 SNOPR, DOE 

referenced AHAM’s current dishwasher 

test method, DW–1–2009, in the 

discussion of its proposal to update 

obsolete flatware, but did not propose to 

incorporate that updated test method. In 

today’s SNOPR, DOE proposes to 

incorporate by reference the updated 

industry test standard AHAM DW–1– 

2009, which upon acceptance by ANSI 

is designated as ANSI/AHAM DW–1– 

2010, American National Standard, 

‘‘Household Electric Dishwashers.’’ DOE 

seeks comment on whether the 

incorporation of this standard will affect 

the measured energy use of dishwashers 

tested according to DOE’s test 

procedure, and if so the magnitude of 

that effect. DOE will determine, as a 

result of these comments, whether to 

retain the current industry standard or 

update the standard to ANSI/AHAM 

DW–1–2010. 

Water Pressure 

In the May 2012 SNOPR, DOE 

proposed that the water supply pressure 

during testing be maintained at 35 ±2.5 

pounds per square in gauge (psig) when 

the water is flowing. DOE received 

comments that, for repeatability and 

reproducibility, the duration of the 

transient pressure drop when the water 

supply valve first opens should be 

minimized. Commenters suggested 

allowing a maximum time of 2 seconds 

to ensure that the water is flowing into 

the dishwasher at the proper pressure 

during the test. DOE agrees that 

transient pressure variations should be 

minimized for reasons of test stability 

and reproducibility, and, based on 

commenters indication of laboratory 

capabilities, proposes to require that 

proper pressure be achieved within 2 

seconds. DOE seeks comment on this 

requirement, in particular whether this 

requirement can be reasonably achieved 

in all laboratories. 

Drain Height 

Drain height is not currently specified 

in the dishwasher test procedure, and 

DOE received comments that such a 

specification should be added to reduce 

testing variability. The commenters 

recommended that the drain height 

should be specified according to the 

manufacturer’s installation instructions. 

In the absence of such instructions, a 

drain height of 20 inches would be 

specified, which according to the 

commenters is a standard height. DOE 

agrees that the use of manufacturer’s 

instructions for drain height, or a 

standard height in the absence of such 

information, would improve 

reproducibility of the test and is 

proposing in today’s SNOPR 

corresponding amendments to the 

dishwasher test procedure, including a 

standard drain height of 20 inches. DOE 

seeks comment and information on the 

standard drain height, and may adjust 

the value accordingly. 

Rack Position and Loading 

Commenters on the May 2012 SNOPR 

noted that the dishwasher test 

procedure does not specify an upper 

rack position or where the soiled dishes 

are placed on the racks, and 

recommended adjusting the rack 

position and loading the soiled 

dishware according to the 

manufacturer’s recommendation. DOE 

concludes that such clarifications would 

improve test repeatability and 

reproducibility, and proposes such 


srobinson on DSK4SPTVN1PROD with PROPOSALS2
Federal Register / Vol. 77, No. 158 / Wednesday, August 15, 2012 / Proposed Rules 49067 

amendments to the dishwasher test 

procedure in today’s SNOPR. DOE seeks 

comment on this proposal. 

Rinse Aid Container 

The dishwasher test procedure 

precludes the use of rinse aid during 

testing, including preconditioning. DOE 

was notified by commenters that some 

laboratories may be filling the rinse aid 

container in certain dishwashers with 

water during testing to prevent the 

energy consumption of an indicator 

light that is energized when the rinse 

aid level is low. However, as one 

commenter noted, the thermal mass of 

the water in the rinse aid container 

would necessitate additional water 

heating energy during the test. For 

consistency in testing, therefore, DOE 

clarifies in today’s SNOPR that the rinse 

aid container should not be filled with 

water for energy testing. DOE welcomes 

comment on this proposal. 

Soil Preparation 

DOE received comments on the May 

2012 SNOPR stating that DOE should 

clarify in the dishwasher test procedure 

the length of time that soils may sit 

before they are applied to the dishware 

to prevent stiffening and settling. DOE 

therefore proposes in today’s SNOPR 

that the test procedure require the 

potatoes be used within 30 minutes of 

preparation and the reconstituted milk 

be allowed to be stored for use over the 

course of 1 day, as recommended by 

commenters. DOE’s proposal includes 

provisions for reconstituting the milk. 

DOE also proposes to adopt the 

commenters’ recommendation that the 

1-pound packages of ground beef shall 

be stored frozen for no more than 6 

months. 

Fan-Only Mode Energy Use 

In the May 2012 SNOPR, DOE 

proposed a test method to measure the 

energy use of dishwashers and cooking 

products in fan-only mode. DOE 

received comments on the May 2012 

SNOPR stating that fan-only mode 

energy use should be measured only if 

it is not a user-selectable item. 

Commenters also indicated that DOE’s 

proposal for measuring the energy use of 

fan-only mode at the end of each test 

cycle would create a considerable test 

burden. In response to these comments, 

DOE continues to consider the approach 

set forth in the May 2012 SNOPR but is 

also considering an alternative 

approach. Under this approach, the 

energy use of fan-only mode would be 

measured only if it is not a userselectable item. DOE understands that 

this change will not significantly alter 

the May 2012 proposal because fan-only 

mode is almost always not a userselectable item. For cooking products, 

fan-only mode runs automatically for 

safety reasons, and for dishwashers, 

DOE understands that fan-only mode 

energy use is not typically selected 

independently but would be a function 

of the drying option selected as part of 

the test cycle. Also under the alternative 

approach, the energy use of fan-only 

mode would be measured for a brief 

time period, such as 10 minutes, and 

then extrapolated over the length of the 

entire fan-only mode cycle, which DOE 

research suggested may range from 10 

minutes to several hours for both 

dishwashers and conventional ovens. 

To adopt this alternative approach, 

however, DOE would need additional, 

representative data on the length of 

these cycle times, so that the 

extrapolation provides an accurate 

measurement of the energy use during 

the fan-only mode cycle. DOE therefore 

seeks representative data on the length 

of the fan-only mode cycle for 

dishwashers and conventional cooking 

products. In the absence of such data, 

DOE may adopt the proposal set forth in 

the May 2012 SNOPR. 

Technical Correction 

In the May 2012 SNOPR, DOE 

inadvertently proposed in section 4.4.2 

of the dishwasher test procedure 

language that refers to section 1.11 of 

the test procedure. DOE corrects that 

proposal in today’s SNOPR to properly 

refer to section 1.13. 

Other than the specific amendments 

newly proposed in today’s SNOPR, DOE 

continues to propose the test procedure 

amendments originally included in the 

December 2010 NOPR and the 

September 2011 SNOPR. For the 

reader’s convenience, DOE has 

reproduced in this SNOPR the entire 

body of proposed regulatory text from 

the December 2010 NOPR and 

September 2011 and May 2012 SNOPRs, 

further amended as appropriate 

according to today’s proposals. DOE’s 

supporting analysis and discussion for 

the portions of the proposed regulatory 

text not affected by this SNOPR may be 

found in the December 2010 NOPR (75 

FR 75290 (Dec. 2, 2010)), the September 

2011 SNOPR (76 FR 58346 (Sept. 20, 

2011)), and the May 2012 SNOPR (77 FR 

31444 (May 25, 2012)). 

B. Compliance With Other EPCA 

Requirements 

EPCA requires test procedures to 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 not 

unduly burdensome to conduct. (42 

U.S.C. 6293(b)(3)) 

For the reasons stated in the 

December 2010 NOPR and September 

2011 and May 2012 SNOPRs, DOE 

tentatively concluded that the amended 

test procedures would produce test 

results that measure the standby mode 

and off mode power consumption 

during representative use, and that the 

test procedures would not be unduly 

burdensome to conduct. DOE continues 

to make these assertions for today’s 

SNOPR because the substituted items 

replace items that DOE determined to 

obsolete, or has received comments in 

this test procedure rulemaking process 

that the items are obsolete. The 

replacement items are intended to be 

inexpensive, representative of 

commonly-found items, and in some 

cases already used by manufacturers in 

testing dishwashers. In addition, DOE is 

proposing a definition of normal cycle 

for dishwashers supported by 

manufacturers because it will lead to 

consistent, representative results. The 

updated industry test method for 

dishwashers was also supported by 

manufactures because it will lead to, 

among other things, reduced test 

variation, as would the proposals for 

consistent preparation time for the soils 

used in the test procedure, the 

positioning of the dishwasher rack 

during testing, the method of loading, 

the tighter tolerances on ambient 

temperature, the added specifications 

for water pressure measurement and 

drain height, and the clarifications for 

the rinse aid container. Finally, DOE is 

proposing an alternative method of 

measuring the energy use in fan-only 

mode for dishwashers and cooking 

products that could significantly 

decrease overall testing time. 

III. Procedural Issues and Regulatory 

Review 

DOE has concluded that the 

determinations made pursuant to the 

various procedural requirements 

applicable to the December 2010 NOPR 

and September 2011 and May 2012 

SNOPRs remain unchanged for this 

SNOPR. These determinations are set 

forth in the December 2010 NOPR (75 

FR 75290, 75317–19 (Dec. 2, 2010)), the 

September 2011 SNOPR (76 FR 58346, 

58355 (Sept. 20, 2011)), and the May 

2012 SNOPR (77 FR 31444, May 25, 

2012). An update to the Regulatory 

Flexibility Act certification is set forth 

below. 

The Regulatory Flexibility Act (5 

U.S.C. 601 et seq.) requires preparation 

of a regulatory flexibility analysis for 

any rule that by law must be proposed 


srobinson on DSK4SPTVN1PROD with PROPOSALS2
49068 Federal Register / Vol. 77, No. 158 / Wednesday, August 15, 2012 / Proposed Rules 

for public comment, unless the agency 

certifies that the rule, if promulgated, 

will not have a significant economic 

impact on a substantial number of small 

entities. As required by Executive Order 

13272, ‘‘Proper Consideration of Small 

Entities in Agency Rulemaking,’’ 67 FR 

53461 (August 16, 2002), DOE 

published procedures and policies on 

February 19, 2003, to ensure that the 

potential impacts of its rules on small 

entities are properly considered during 

the DOE rulemaking process. 68 FR 

7990. DOE has made its procedures and 

policies available on the Office of the 

General Counsel’s Web site: 

www.gc.doe.gov. 

DOE reviewed today’s supplemental 

proposed rule under the provisions of 

the Regulatory Flexibility Act and the 

procedures and policies published on 

February 19, 2003. DOE tentatively 

concluded that the December 2010 

NOPR and September 2011 SNOPR 

would not have a significant impact on 

a substantial number of small entities, 

and today’s SNOPR contains no 

revisions to that proposal that would 

result in a significant impact on a 

substantial number of small entities. 

The updates to the factual basis for this 

certification are as follows: 

The Small Business Administration 

(SBA) considers a business entity to be 

small business, if, together with its 

affiliates, it employs less than a 

threshold number of workers specified 

in 13 CFR part 121. These size standards 

and codes are established by the North 

American Industry Classification 

System (NAICS). The threshold number 

for NAICS classification code 335228, 

titled ‘‘Other Major Household 

Appliance Manufacturing,’’ is 500 

employees; this classification 

specifically includes residential 

dishwasher manufacturers. 

Additionally, the threshold number for 

NAICS classification code 335221, titled 

‘‘Household Cooking Appliance 

Manufacturing,’’ is 750 employees; this 

classification specifically includes 

manufacturers of residential 

conventional cooking products. The 

threshold number for NAICS 

classification code 335211, titled 

‘‘Electric Housewares and Household 

Fan Manufacturing,’’ is 750 employees; 

this classification specifically includes 

manufacturers of dehumidifiers. 

DOE surveyed the AHAM member 

directory to identify manufacturers of 

residential dishwashers and 

conventional cooking products. DOE 

then consulted publicly-available data, 

purchased company reports from 

vendors such as Dun and Bradstreet, 

and contacted manufacturers, where 

needed, to determine if they meet the 

SBA’s definition of a ‘‘small business 

manufacturing facility’’ and have their 

manufacturing facilities located within 

the United States. Based on this 

analysis, DOE estimates that there are 

no small businesses that manufacture 

dishwashers and two small businesses 

that manufacture conventional cooking 

products. Only one provision of today’s 

supplemental proposal would affect 

manufacturers of conventional cooking 

products, the alternative proposal to 

measure the energy use in fan-only 

mode. Under today’s supplemental 

proposal, that energy use would not be 

measured at the end of each test cycle. 

Rather, the energy use in fan-only mode 

would be measured for a brief period, 

such as 10 minutes, and then 

extrapolated over the duration of the 

entire cycle. This proposal could 

significantly decrease the test burden for 

manufacturers of conventional cooking 

products. 

For these reasons, DOE continues to 

certify that the proposed rule would not 

have a significant economic impact on 

a substantial number of small entities. 

Accordingly, DOE has not prepared a 

regulatory flexibility analysis for this 

rulemaking. DOE will transmit the 

certification and supporting statement 

of factual basis to the Chief Counsel for 

Advocacy of the SBA for review under 

5 U.S.C. 605(b). DOE seeks comment on 

the updates to the certification that are 

set forth above.

Otherwise, if a maximum total of 10 cycles 

have been conducted and no cycle is 

determined to have water consumption that 

is 10 percent higher than the average water 

consumption of the other cycles, then the 

unit shall be deemed not a water-softening 

dishwasher. 

4.2 Active mode cycle. Perform a test 

cycle by establishing the testing conditions 

set forth in section 2 of this Appendix, 

setting the dishwasher to the cycle type to be 

tested according to section 2.6.1.2, 2.6.2.2, or 

2.6.3.2 of this Appendix, initiating the cycle, 

and allowing the cycle to proceed to 

completion.

wattmeter or a standby watt-hour meter as 

specified in sections 3.6 and 3.7, 

respectively, of this Appendix. Select the 

conditions necessary to achieve operation in 

the simplified standby mode as defined in 

section 1.19 of this Appendix. Monitor the 

power consumption but allow the 

dishwasher to stabilize for at least 5 minutes. 

Then monitor the power consumption for at 

least an additional 5 minutes. If the power 

level does not change by more than 5 percent 

from the maximum observed value during 

the later 5 minutes and if there is no cyclic 

or pulsing behavior of the load, the load can 

be considered stable. For stable operation, 

simplified standby mode power, Sm, can be 

recorded directly from the standby watt 

meter in watts or accumulated using the 

standby watt-hour meter over a period of at 

least 5 minutes. For unstable operation, the 

energy must be accumulated using the 

standby watt-hour meter over a period of at 

least 5 minutes and must capture the energy 

use over one or more complete cycles. 

Calculate the average simplified standby 

mode power, Sm, expressed in watts by 

dividing the accumulated energy 

consumption by the duration of the 

measurement period. 

4.4 Standby mode and off mode power. 

Connect the dishwasher to a standby mode 

and off mode watt meter as specified in 

section 3.8 of this Appendix. Establish the 

testing conditions set forth in sections 2.1, 

2.2, and 2.5.2 of this Appendix. For 

dishwashers that take some time to enter a 

stable state from a higher power state as 

discussed in Section 5, Paragraph 5.1, note 1 

of IEC 62301 (incorporated by reference; see 

§ 430.3), allow sufficient time for the 

dishwasher to reach the lower power state 

before proceeding with the test measurement. 

Follow the test procedure specified in 

Section 5, Paragraph 5.3.2 of IEC 62301 for 

testing in each possible mode as described in 

sections 4.4.1 and 4.4.2 of this Appendix.

Appendix I to Subpart B of Part 430— 

Uniform Test Method for Measuring the 

Energy Consumption of Conventional 

Ranges, Conventional Cooking Tops, 

Conventional Ovens, and Microwave 

Ovens 

Note: The procedures and calculations in 

this Appendix I need not be performed to 

determine compliance with energy 

conservation standards for conventional 

ranges, conventional cooking tops, 

conventional ovens, and microwave ovens at 

this time. However, any representation 

related to standby mode and off mode energy 

consumption of conventional ranges, 

conventional cooking tops, and conventional 

ovens made after (date 180 days after date of 

publication of the test procedure final rule in 

the Federal Register) and of microwave 

ovens made after September 6, 2011 must be 

based upon results generated under this test 

procedure, consistent with the requirements 

of 42 U.S.C. 6293(c)(2). Upon the compliance 

date of any energy conservation standard that 

incorporates standby mode and off mode 

energy consumption, compliance with the 

applicable provisions of this test procedure 

will also be required. Future revisions may 

add relevant provisions for measuring active 

mode in microwave ovens. 

1. Definitions 

1.1 Active mode means a mode in which 

the product is connected to a mains power 

source, has been activated, and is performing 

the main functions of producing heat by 

means of a gas flame, electric resistance 

heating, or microwave energy, or circulating 

air internally or externally to the cooking 

product. Delay start mode is a one-off, userinitiated, short-duration function that is 

associated with an active mode. 

1.2 Built-in means the product is 

supported by surrounding cabinetry, walls, 

or other similar structures. 

1.3 Combined low-power mode means the 

aggregate of available modes other than 

active mode. 

1.4 Cycle finished mode means a standby 

mode in which a conventional cooking top, 

conventional oven, or conventional range 

provides continuous status display following 

operation in active mode. 

1.5 Drop-in means the product is 

supported by horizontal surface cabinetry. 

1.6 Fan-only mode means an active mode 

that is not user-selectable and in which a fan 

circulates air internally or externally to the 

cooking product for a finite period of time 

after the end of the heating function, as 

indicated to the consumer. 

1.7 Forced convection means a mode of 

conventional oven operation in which a fan 

is used to circulate the heated air within the 

oven compartment during cooking. 

1.8 Freestanding means the product is not 

supported by surrounding cabinetry, walls, 

or other similar structures. 

1.9 IEC 62301 First Edition means the test 

standard published by the International 

Electrotechnical Commission, titled

‘‘Household electrical appliances— 

Measurement of standby power,’’ Publication 

62301 (Edition 2.0 2011–01) (incorporated by 

reference; see § 430.3). 

1.11 Inactive mode means a standby 

mode that facilitates the activation of active 

mode by remote switch (including remote 

control), internal sensor, or timer, or that 

provides continuous status display. 

1.12 Normal nonoperating temperature 

means the temperature of all areas of an 

appliance to be tested are within 5 °F (2.8 °C) 

of the temperature that the identical areas of 

the same basic model of the appliance would 

attain if it remained in the test room for 24 

hours while not operating with all oven 

doors closed. 

1.13 Off mode means a mode in which 

the product is connected to a mains power 

source and is not providing any active mode 

or standby mode function, and where the 

mode may persist for an indefinite time. An 

indicator that only shows the user that the 

product is in the off position is included 

within the classification of an off mode. 

1.14 Primary energy consumption means 

either the electrical energy consumption of a 

conventional electric oven or the gas energy 

consumption of a conventional gas oven. 

1.15 Secondary energy consumption 

means any electrical energy consumption of 

a conventional gas oven. 

1.16 Standard cubic foot (L) of gas means 

that quantity of gas that occupies 1 cubic foot 

(L) when saturated with water vapor at a 

temperature of 60 °F (15.6 °C) and a pressure 

of 30 inches of mercury (101.6 kPa) (density 

of mercury equals 13.595 grams per cubic 

centimeter).

modes (including activation or deactivation 

of active mode) by remote switch (including 

remote control), internal sensor, or timer; (b) 

continuous functions, including information 

or status displays (including clocks) or 

sensor-based functions. A timer is a 

continuous clock function (which may or 

may not be associated with a display) that 

provides regular scheduled tasks (e.g., 

switching) and that operates on a continuous 

basis. 

1.18 Thermocouple means a device 

consisting of two dissimilar metals which are 

joined together and, with their associated 

wires, are used to measure temperature by 

means of electromotive force.

3. Test Methods and Measurements 

* * * * * 

3.1.1 Conventional oven. Perform a test 

by establishing the testing conditions set 

forth in section 2, Test Conditions, of this 

Appendix and turn off the gas flow to the 

conventional cooking top, if so equipped. 

Before beginning the test, the conventional 

oven shall be at its normal nonoperating 

temperature as defined in section 1.12 and 

described in section 2.6 of this Appendix. Set 

the conventional oven test block W1

approximately in the center of the usable 

baking space. If there is a selector switch for 

selecting the mode of operation of the oven, 

set it for normal baking. If an oven permits 

baking by either forced convection by using 

a fan, or without forced convection, the oven 

is to be tested in each of those two modes. 

The oven shall remain on for one complete 

thermostat ‘‘cut-off/cut-on’’ of the electrical 

resistance heaters or gas burners after the test 

block temperature has increased 234 °F (130 

°C) above its initial temperature. 

3.1.1.1 Self-cleaning operation of a 

conventional oven. Establish the test 

conditions set forth in section 2, Test 

Conditions, of this Appendix. Turn off the 

gas flow to the conventional cooking top. The 

temperature of the conventional oven shall 

be its normal nonoperating temperature as 

defined in section 1.12 and described in 

section 2.6 of this Appendix. Then set the 

conventional oven’s self-cleaning process in 

accordance with the manufacturer’s 

instructions. If the self-cleaning process is 

adjustable, use the average time 

recommended by the manufacturer for a 

moderately soiled oven. 

3.1.1.2 Conventional oven standby mode 

and off mode power. Establish the standby 

mode and off mode testing conditions set 

forth in section 2, Test Conditions, of this 

Appendix. For conventional ovens that take 

some time to enter a stable state from a 

higher power state as discussed in Section 5, 

Paragraph 5.1, Note 1 of IEC 62301 (Second 

Edition) (incorporated by reference; see 

§ 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. For units in which power varies as 

a function of displayed time in standby 

mode, either: (1) Set the clock time to 3:23 

at the end of the stabilization period 

specified in Section 5, 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; or (2) at any starting clock time, 

allow a stabilization period as described 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 12 hours +0/¥30 sec. Testing 

may be conducted using either a 12-hour test, 

a 10-minute test, or both tests; however, if a 

manufacturer elects to perform both tests on 

a unit, the manufacturer may only use the 

results from one of the tests (i.e., the 12-hour 

test or the 10-minute test) as the test results 

for that unit. Results of the 10-minute test 

that are within ±2 percent of the 12-hour test 

are deemed to be representative of average 

energy use. 

3.1.1.2.1 If the conventional oven has an 

inactive mode, as defined in section 1.11 of 

this Appendix, measure and record the 

average inactive mode power of the 

conventional oven, PIA, in watts. 

3.1.1.2.2 If the conventional oven has an 

off mode, as defined in section 1.13 of this 

Appendix, measure and record the average 

off mode power of the conventional oven, 

POM, in watts. 

3.1.2 Conventional cooking top. Establish 

the test conditions set forth in section 2, Test 

Conditions, of this Appendix. Turn off the 

gas flow to the conventional oven(s), if so 

equipped. The temperature of the

Appendix X to Subpart B of Part 430— 

Uniform Test Method for Measuring the 

Energy Consumption of Dehumidifiers 

Note: The procedures and calculations that 

refer to standby mode and off mode energy 

consumption (i.e., sections 3.2, 3.2.1 through 

3.2.4, 4.2, 4.2.1 through 4.2.4, 5.1, and 5.2 of 

this Appendix X) need not be performed to 

determine compliance with energy 

conservation standards for dehumidifiers at 

this time. However, any representation 

related to standby mode and off mode energy 

consumption of these products made after 

(date 180 days after date of publication of the 

test procedure final rule in the Federal 

Register) must be based upon results 

generated under this test procedure, 

consistent with the requirements of 42 U.S.C. 

6293(c)(2). Upon the compliance date for any 

energy conservation standards that 

incorporate standby mode and off mode 

energy consumption, compliance with the 

applicable provisions of this test procedure 

will be required. 

1. Scope 

This Appendix covers the test 

requirements used to measure the energy 

performance of dehumidifiers.

2. Definitions 

a. ANSI/AHAM DH–1 means the test 

standard published by the American National 

Standards Institute and the Association of 

Home Appliance Manufacturers, titled 

‘‘Dehumidifiers,’’ ANSI/AHAM DH–1–2008, 

(incorporated by reference; see § 430.3). 

b. Active mode means a mode in which a 

dehumidifier is connected to a mains power 

source, has been activated, and is performing 

the main functions of removing moisture 

from air by drawing moist air over a 

refrigerated coil using a fan, or circulating air 

through activation of the fan without 

activation of the refrigeration system. 

c. Bucket full/removed mode means a 

standby mode in which the dehumidifier has 

automatically powered off its main function 

by detecting when the water bucket is full or 

has been removed. 

d. Energy factor for dehumidifiers means a 

measure of energy efficiency of a 

dehumidifier calculated by dividing the 

water removed from the air by the energy 

consumed, measured in liters per kilowatthour (L/kWh). 

e. IEC 62301 means the test standard 

published by the International 

Electrotechnical Commission, titled 

‘‘Household electrical appliances— 

Measurement of standby power,’’ Publication 

62301 (Edition 2.0 2011–01) (incorporated by 

reference; see § 430.3). 

f. Inactive mode means a standby mode 

that facilitates the activation of active mode 

by remote switch (including remote control), 

internal sensor, or timer, or that provides 

continuous status display. 

g. Off mode means a mode in which the 

dehumidifier is connected to a mains power 

source and is not providing any active mode 

or standby mode function, and where the 

mode may persist for an indefinite time. An 

indicator that only shows the user that the 

dehumidifier is in the off position is 

included within the classification of an off 

mode. 

h. Off-cycle mode means a standby mode 

in which the dehumidifier: 

(1) Has cycled off its main function by 

humidistat or humidity sensor; 

(2) Does not have its fan or blower 

operating; and 

(3) Will reactivate the main function 

according to the humidistat or humidity 

sensor signal. 

i. Product capacity for dehumidifiers 

means a measure of the ability of the 

dehumidifier to remove moisture from its 

surrounding atmosphere, measured in pints 

collected per 24 hours of continuous 

operation. 

j. Standby mode means any modes where 

the dehumidifier is connected to a mains 

power source and offers one or more of the 

following user-oriented or protective 

functions which may persist for an indefinite 

time: 

(1) To facilitate the activation of other 

modes (including activation or deactivation 

of active mode) by remote switch (including 

remote control), internal sensor, or timer; 

(2) Continuous functions, including 

information or status displays (including 

clocks) or sensor-based functions. A timer is 

a continuous clock function (which may or 

may not be associated with a display) that 

provides regular scheduled tasks (e.g., 

switching) and that operates on a continuous 

basis.

(incorporated by reference, see § 430.3). 

Record measurements at the resolution of the 

test instrumentation. Round off calculations 

to the same number of significant digits as 

the previous step. Round the final minimum 

energy factor value to two decimal places as 

follows: 

(i) A fractional number at or above the 

midpoint between two consecutive decimal 

places shall be rounded up to the higher of 

the two decimal places; or

watt-hours to kilowatt-hours. 

5.2 Integrated energy factor. Calculate the 

integrated energy factor, IEF, expressed in 

liters per kilowatt-hour, rounded to two 

decimal places, according to the following: 

IEF = LW/(Eactive + ((ETSO × 24)/Sactive)) 

Where: 

LW = water removed from the air during 

dehumidifier energy factor test, in liters, 

as measured in section 4.1 of this 

Appendix. 

Eactive = dehumidifier energy factor test 

energy consumption, in kilowatt-hours, 

as measured in section 4.1 of this 

Appendix. 

ETSO = standby mode and off mode annual 

energy consumption, in kilowatt-hours 

per year, as calculated in section 5.1 of 

this Appendix. 

24 = hours per day. 

Sactive = 1,095, dehumidifier active mode 

annual hours.
