[Docket No. EERE–2010–BT–TP–0039] 

RIN: 1904–AC27 

Energy Conservation Program for 

Consumer Products: Test Procedures 

for Residential Dishwashers, 

Dehumidifiers, and Conventional 

Cooking Products (Standby Mode and 

Off Mode) 

AGENCY: Office of Energy Efficiency and 

Renewable Energy, Department of 

Energy. 

ACTION: Notice of proposed rulemaking 

and announcement of public meeting. 

SUMMARY: In order to implement recent 

amendments to the Energy Policy and 

Conservation Act of 1975 (EPCA), the 

U.S. Department of Energy (DOE) 

proposes to amend its test procedures 

for residential dishwashers, 

dehumidifiers, and conventional 

cooking products (which include 

cooktops, ovens, and ranges) to provide 

for measurement of standby mode and 

off mode energy use by these products. 

The proposed amendments would 

incorporate into the DOE test 

procedures relevant provisions from the 

International Electrotechnical 

Commission’s (IEC) Standard 62301, 

‘‘Household electrical appliances— 

Measurement of standby power,’’ First 

Edition 2005–06 (IEC Standard 62301 

(First Edition)). DOE also proposes to 

adopt definitions of various modes of 

operation based on the relevant 

provisions from the IEC Standard 62301 

‘‘Household electrical appliances— 

Measurement of standby power,’’ 

Second Edition Final Draft International 

Standard (IEC Standard 62301 (FDIS)). 

In addition, DOE proposes to adopt 

language to clarify application of these 

test procedure provisions for measuring 

standby mode and off mode power 

consumption in dishwashers, 

dehumidifiers, and conventional 

cooking products. Furthermore, the 

proposed amendments would add new 

calculations to determine annual energy 

consumption associated with the 

standby mode and off mode measured 

power. Finally, the amendments would 

modify existing energy consumption 

equations to integrate standby mode and 

off mode energy consumption into the 

calculation of overall annual energy 

consumption and annual operating cost 

of those products which already have 

definitions for such measures 

(dishwashers and conventional cooking 

products). DOE is also announcing a 

public meeting to discuss and receive 

comments on the issues presented in 

this notice. 

DATES: Meeting: DOE will hold a public 

meeting on Friday, December 17, 2010, 

from 9 a.m. to 4 p.m., in Washington, 

DC. DOE must receive requests to speak 

at the public meeting before 4 p.m., 

Friday, December 3, 2010. DOE must 

receive a signed original and an 

electronic copy of statements to be given 

at the public meeting before 4 p.m., 

Friday, December 10, 2010. 

Comments: DOE will accept 

comments, data, and information 

regarding the notice of proposed 

rulemaking (NOPR) before and after the 

public meeting, but no later than 

February 15, 2011. For details, see

I. Background and Authority 

Title III, Part B of the Energy Policy 

and Conservation Act of 1975 (EPCA), 

Public Law 94–163 (42 U.S.C. 6291– 

6309, as codified), established the 

‘‘Energy Conservation Program for 

Consumer Products Other Than 

Automobiles,’’ a program covering most 

major household appliances, including 

residential dishwashers, conventional 

cooking products, and dehumidifiers,1

the subjects of today’s notice.2 (42 

U.S.C. 6292(a)(6) and (10); 6295(cc)) 

Under the Act,3 this program consists 

essentially of three parts: (1) Testing; 

(2) labeling; and (3) Federal energy 

conservation standards. 

Manufacturers of covered products 

must use DOE test procedures, 

prescribed under EPCA, to certify that 

their products comply with the energy 

conservation standards adopted under 

EPCA and to represent the energy 

consumption or energy efficiency of 

their products. (42 U.S.C. 6293(c); 42 

U.S.C. 6295(s)) DOE must also use DOE 

test procedures in any enforcement 

action to determine whether covered 

products comply with these energy 

conservation standards. (42 U.S.C. 

6295(s)) Criteria and procedures for 

DOE’s adoption and amendment of such 

test procedures, as set forth in EPCA, 

require 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. Test 

procedures must also not be unduly 

burdensome to conduct. (42 U.S.C. 

6293(b)(3)) 

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)) 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)) 

Dishwashers 

DOE’s test procedure for dishwashers 

is found in the Code of Federal 

Regulations (CFR) at 10 CFR part 430, 

subpart B, appendix C. DOE originally 

established its test procedure for 

dishwashers in 1977. 42 FR 39964 

(August 8, 1977). Since that time, the 

dishwasher test procedure has 

undergone a number of amendments, as 

discussed below. In 1983, DOE 

amended the test procedure to revise the 

representative average-use cycles to 

more accurately reflect consumer use 

and to address dishwashers that use 120 

°F inlet water. 48 FR 9202 (March 3, 

1983). DOE amended the test procedure 

again in 1984 to redefine the term 

‘‘water heating dishwasher.’’ 49 FR 

46533 (Nov. 27, 1984). In 1987, DOE 

amended the test procedure to address 

models that use 50 °F inlet water. 52 FR 

47549 (Dec. 15, 1987). In 2001, DOE 

revised the test procedure’s testing 

specifications to improve testing 

repeatability, changed the definitions of 

‘‘compact dishwasher’’ and ‘‘standard 

dishwasher,’’ and reduced the average 

number of use cycles per year from 322 

to 264. 66 FR 65091, 65095–97 (Dec. 18, 

2001). In 2003, DOE again revised the 

test procedure to more accurately 

measure dishwasher efficiency, energy 

use, and water use. The 2003 

dishwasher test procedure amendments 

included the following revisions: 

(1) The addition of a method to rate the 

efficiency of soil-sensing products; 

(2) the addition of a method to measure 

standby power; and (3) a reduction in 

the average-use cycles per year from 264 

to 215. 68 FR 51887, 51899–903 (August 

29, 2003). The current version of the test 

procedure includes provisions for 

determining estimated annual energy 

use (EAEU), estimated annual operating 

cost (EAOC), energy factor (EF) 

expressed in cycles per kilowatt-hour 

(kWh), and water consumption 

expressed in gallons per cycle. (10 CFR 

430.23(c)) 

The National Appliance Energy 

Conservation Act of 1987 (NAECA), 

Public Law 100–12, amended EPCA to 

establish prescriptive standards for 

dishwashers, requiring that dishwashers 

manufactured on or after January 1, 

1988, be equipped with an option to dry 

without heat. (42 U.S.C. 6295(g)(1)) 

These EPCA amendments also 

mandated that DOE must conduct two 

rounds of rulemaking to determine 

whether the energy conservation 

standards for dishwashers should be 

amended. (42 U.S.C. 6295(g)(4)) On May 

14, 1991, DOE issued a final rule 

establishing the first set of performance 

standards for dishwashers. 56 FR 22250. 

The final rule required that dishwashers 

manufactured on or after May 14, 1994, 

must have a minimum EF of 0.46 cycles 

per kWh for standard size, and 0.62 

cycles per kWh for compact size. Id. at 

22279; 10 CFR 430.32(f)(1). 

The Energy Independence and 

Security Act of 20074 (EISA 2007) 

further amended EPCA, in relevant part 

by establishing the following energy 

conservation standards for residential 

dishwashers manufactured on or after 

January 1, 2010: (1) For standard size

dishwashers, a maximum annual energy 

use of 355 kWh per year, and a 

maximum water consumption of 6.5 

gallons per cycle; and (2) for compact 

dishwashers, a maximum annual energy 

use of 260 kWh per year, and a 

maximum water consumption of 4.5 

gallons per cycle. (42 U.S.C. 

6295(g)(10)(A); 10 CFR 430.32(f)(2)) The 

amendments also specify that not later 

than January 1, 2015, the Secretary shall 

publish a final rule determining 

whether to amend the standards for 

dishwashers manufactured on or after 

January 1, 2018. (42 U.S.C. 

6295(g)(10)(B)) 

Dehumidifiers 

The DOE test procedure for 

dehumidifiers is found at 10 CFR 430, 

subpart B, appendix X. The Energy 

Policy Act of 2005 (EPACT 2005), 

Public Law 109–58, amended EPCA to 

specify that the U.S. Environmental 

Protection Agency’s (EPA) test criteria 

used under the ENERGY STAR® 5

program must serve as the basis for the 

test procedure for dehumidifiers. 

(EPACT 2005, section 135(b); 42 U.S.C. 

6293(b)(13)) The ENERGY STAR test 

criteria require that American National 

Standards Institute (ANSI)/Association 

of Home Appliance Manufacturers 

(AHAM) Standard DH–1–2003, 

‘‘Dehumidifiers,’’ be used to measure 

energy use and that the Canadian 

Standards Association (CAN/CSA) 

standard CAN/CSA–C749–1994 

(R2005), ‘‘Performance of 

Dehumidifiers,’’ be used to calculate EF. 

DOE has adopted these test criteria, 

along with related definitions and 

tolerances, as its test procedure for 

dehumidifiers. 71 FR 71340, 71347, 

71366–68 (Dec. 8, 2006). The DOE test 

procedure provides methods for 

determining the EF for dehumidifiers, 

which is expressed in liters (l) of water 

condensed per kWh. 

Section 135(c)(4) of EPACT 2005 

added dehumidifiers as products 

covered under EPCA and established 

standards effective for dehumidifiers 

manufactured on or after October 1, 

2007. (42 U.S.C. 6295(cc)(1)) Section 

311 of EISA 2007 further amended 

EPCA to revise the energy conservation 

standards for dehumidifiers, 

establishing the following minimum EFs 

based on product capacity for 

dehumidifiers manufactured on or after 

October 1, 2012:

Conventional Cooking Products 

DOE’s test procedures for 

conventional ranges, cooktops, and 

ovens (including microwave ovens) are 

found at 10 CFR 430, subpart B, 

appendix I. DOE first established the 

test procedures included in appendix I 

in a final rule published in the Federal 

Register on May 10, 1978. 43 FR 20108, 

20120–28. DOE revised its test 

procedure for cooking products to more 

accurately measure their efficiency and 

energy use, and published the revisions 

as a final rule in 1997. 62 FR 51976 

(Oct. 3, 1997). These test procedure 

amendments included: (1) A reduction 

in the annual useful cooking energy; 

(2) a reduction in the number of selfcleaning oven cycles per year; and 

(3) incorporation of portions of IEC 

Standard 705–1988, ‘‘Methods for 

measuring the performance of 

microwave ovens for household and 

similar purposes,’’ and Amendment 

2–1993 for the testing of microwave 

ovens. Id. The test procedure for 

conventional cooking products 

establishes provisions for determining 

EAOC, cooking efficiency (defined as 

the ratio of cooking energy output to 

cooking energy input), and EF (defined 

as the ratio of annual useful cooking 

energy output to total annual energy 

input). (10 CFR 430.23(i); 10 CFR part 

430 subpart B, appendix I) These 

provisions for conventional cooking 

products are not currently used for 

compliance with any energy 

conservation standards (because those 

standards currently involve design 

requirements), nor is there an 

EnergyGuide 6 labeling program for 

cooking products. 

DOE has initiated a separate test 

procedure rulemaking to address 

standby mode and off mode power 

consumption for microwave ovens. This 

rulemaking was initiated separately in 

response to comments from interested 

parties on the advance notice of 

proposed rulemaking (ANOPR) for an 

earlier rulemaking concerning energy 

conservation standards for dishwashers, 

dehumidifiers, cooking products, and 

commercial clothes washers published 

on November 15, 2007 (hereafter 

referred to as the November 2007 

ANOPR) (72 FR 64432), prior to the 

enactment of EISA 2007. As discussed 

in the October 2008 test procedure 

NOPR, interested parties stated 

generally that DOE should amend the 

test procedures for all types of cooking 

products to allow for measurement of 

standby mode energy use in order to 

implement a standby power energy 

conservation standard. 73 FR 62034, 

62043–44 (Oct. 17, 2008). However, 

DOE did not receive any specific data or 

inputs on standby power consumption 

in conventional cooking products. Also, 

at that time, interested parties did not 

submit any comments regarding DOE 

addressing new measures of standby 

mode and off mode energy use in the 

test procedures or energy conservation 

standards for the other products that 

were the subject of the November 2007 

ANOPR (i.e., dishwashers and 

dehumidifiers.) Because DOE agreed 

with the comments supporting new 

measures of standby mode and off mode 

energy use for microwave ovens and the 

potential for early adoption of an energy 

conservation standard for microwave 

ovens addressing standby mode and off 

mode energy consumption, DOE 

published a NOPR proposing 

amendments to just the microwave oven 

test procedure for standby mode and off 

mode in the Federal Register on 

October 17, 2008. 73 FR 62134. DOE 

subsequently published a supplemental 

notice of proposed rulemaking (SNOPR) 

in the Federal Register on this topic on 

July 22, 2010. 75 FR 42612. 

Consequently, DOE is proposing 

amendments to its cooking products test 

procedure for only conventional 

cooking products in today’s NOPR. 

As with dishwashers, NAECA 

amended EPCA to establish prescriptive 

standards for cooking products. The 

NAECA amendments required gas 

ranges and ovens with an electrical 

supply cord manufactured on or after 

January 1, 1990, not to be equipped with 

a constant-burning pilot light. (42 U.S.C. 

6295(h)(1)) Subsequently, DOE 

published a final rule in the Federal 

Register on April 8, 2009, amending the 

energy conservation standard for 

cooking products to require for products 

manufactured on or after April 9, 2012, 

that gas cooking products without an 

electrical supply cord shall not be 

equipped with a constant burning pilot 

light. 74 FR 16040, 16094. 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 75293 

7EISA 2007 directs DOE to also consider IEC 

Standard 62087 when amending its test procedure 

to include standby mode and off mode energy 

consumption. See 42 U.S.C. 6295(gg)(2)(A). 

However, IEC Standard 62087 addresses the 

methods of measuring the power consumption of 

audio, video, and related equipment. As explained 

subsequently in this notice, the narrow scope of this 

particular IEC standard reduces its relevance to 

today’s proposal. 

Standby Mode and Off Mode 

Section 310 of EISA 2007 amended 

EPCA to require DOE to amend the test 

procedures for covered products to 

address standby mode and off mode 

energy consumption. Specifically, the 

amendments also require DOE to 

integrate standby mode and off mode 

energy consumption into the overall 

energy efficiency, energy consumption, 

or other energy descriptor for that 

product unless the current test 

procedures already fully account for 

such consumption. If integration is 

technically infeasible, DOE must 

prescribe a separate standby mode and 

off mode energy use test procedure, if 

technically feasible. (42 U.S.C. 

6295(gg)(2)(A)) Any such amendment 

must consider the most current versions 

of IEC Standards 62301, ‘‘Household 

electrical appliances—Measurement of 

standby power,’’ and IEC Standard 

62087, ‘‘Methods of measurement for the 

power consumption of audio, video, and 

related equipment.’’ Id. For residential 

dishwashers, dehumidifiers, and 

conventional cooking products (and 

microwave ovens), DOE must prescribe 

any such amendment to the test 

procedures by final rule no later than 

March 31, 2011. (42 U.S.C. 

6295(gg)(2)(B)(vi)) Furthermore, EISA 

2007 also amended EPCA to direct DOE 

to incorporate standby mode and off 

mode energy use into any final rule 

establishing or revising an energy 

conservation standard for a covered 

product adopted after July 1, 2010. If it 

is not feasible to incorporate standby 

mode and off mode into a single 

amended or new standard, then the 

statute requires DOE to prescribe a 

separate standard to address standby 

mode and off mode energy 

consumption. (42 U.S.C. 6295(gg)(3)) 

DOE notes that the IEC is in the 

process of developing a revised version 

of IEC Standard 62301, which was 

expected to be released by July 2009. 

This revision is expected to be 

significantly delayed until late 2010 at 

the earliest. In order to publish a final 

rule by March 31, 2011, DOE is 

proceeding with an amended test 

procedure based on the current version 

of IEC Standard 62301 (First Edition). 

However, DOE is also considering the 

updated mode of operation definitions 

in the latest draft version of IEC 

Standard 62301, IEC Standard 62301 

(FDIS). Although not formally adopted, 

DOE is evaluating the substance of those 

definitions, which are expected to be 

included in the final revised IEC 

Standard 62301 (Second Edition). 

DOE acknowledges that the current 

dishwasher test procedure already 

includes definitions and testing 

methods for measuring standby mode 

power consumption similar to the IEC 

Standard 62301 (First Edition) 

provisions, but it does not include 

definitions and testing methods for 

measuring multiple standby modes and 

off mode power consumption. However, 

in today’s NOPR, for the reasons 

discussed in section III.B, DOE proposes 

amendments to the current dishwasher 

test procedure in order to fully account 

for standby mode and off mode power 

consumption. These amendments 

would take into consideration the most 

current versions of IEC Standards 62301 

and 62087. 

The current DOE dehumidifier test 

procedure does not address energy use 

when the product is in standby mode 

and off mode. For this reason, in today’s 

NOPR, DOE is proposing amendments 

to its dehumidifier test procedure to 

provide for the measurement of standby 

mode and off mode energy 

consumption. 

The current DOE conventional 

cooking products test procedure does 

not fully account for standby mode and 

off mode energy consumption. However, 

DOE notes that the test procedures, as 

currently drafted, do account for 

standby energy use in narrow cases. The 

DOE conventional cooking products test 

procedures include provisions for 

determining the annual energy 

consumption of a continuouslyoperating clock, as well as the standby 

energy use associated with a 

continuously-burning pilot light for gas 

cooking products. Otherwise, the test 

procedure does not address energy use 

in standby mode or off mode. For this 

reason, in today’s NOPR, DOE proposes 

amendments to the conventional 

cooking products test procedures to 

fully account for standby mode and off 

mode power consumption. 

II. Summary of the Proposal 

In today’s NOPR, DOE proposes to 

amend the test procedures for 

dishwashers, dehumidifiers, and 

conventional cooking products in order 

to: 

(1) Provide a foundation for DOE to 

develop and implement standards that 

address use of standby mode and off 

mode power by these products; and 

(2) Address the statutory requirement 

to expand test procedures to incorporate 

measures of standby mode and off mode 

power consumption. 

In general, DOE proposes to 

incorporate by reference into the test 

procedures for these products specific 

provisions from IEC Standard 62301 

(First Edition) regarding test conditions 

and test procedures for measuring 

standby mode and off mode power 

consumption, and to include language 

that would clarify the application of 

such provisions. DOE also proposes to 

incorporate into each test procedure the 

definitions of ‘‘active mode,’’ ‘‘standby 

mode,’’ and ‘‘off mode’’ that are based on 

the definitions for those terms provided 

in IEC Standard 62301 (FDIS). Further, 

DOE proposes to include in each test 

procedure additional language that 

would clarify the application of clauses 

from IEC Standard 62301 (First Edition) 

for measuring standby mode and off 

mode power consumption.7

As an initial matter, DOE had to 

analyze a number of product-specific 

modes in order to determine whether 

they should be characterized as active 

mode, standby mode, or off mode 

functions. As discussed in further detail 

below, this rulemaking is limited to 

addressing standby mode and off mode. 

Based upon the results of its analyses, 

DOE is proposing the following productspecific amendments to the applicable 

DOE test procedures. For dishwashers, 

DOE is proposing definitions for the 

following different standby modes: 

(1) A general ‘‘inactive’’ mode; and (2) a 

‘‘cycle finished’’ mode. For 

dehumidifiers, DOE is proposing 

definitions for the following different 

standby modes: (1) a general ‘‘inactive’’ 

mode; (2) an ‘‘off-cycle’’ mode; and (3) a 

‘‘bucket full/removed’’ mode. For 

conventional cooking products, DOE is 

also proposing definitions for the 

following different standby modes: 

(1) A general ‘‘inactive’’ mode; and (2) a 

‘‘cycle finished’’ mode. For each 

product, energy use in each standby 

mode, as well as energy use in the off 

mode, would be separately tested under 

the appropriate procedure and 

incorporated into an integrated energy 

efficiency metric for that product. 

The current DOE dishwasher test 

procedure already includes provisions 

for measuring standby power and 

includes it in the EAEU and EAOC 

calculations. However, as discussed 

earlier, DOE is proposing amendments 

to the dishwasher test procedure, 

pursuant to EPCA, to fully and more 

accurately account for standby mode 

and off mode power consumption based 

on provisions in IEC Standard 62301. As 

a result, DOE is proposing revisions to 

the EAEU and EAOC calculations to 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
75294 Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 

8 DOE notes that it published a final rule in the 

Federal Register on April 8, 2009, establishing 

standards that prohibit continuously-burning pilot 

lights for gas cooking products manufactured on or 

after April 9, 2012. 74 FR 16040, 16094. 

incorporate the revised measurements of 

standby mode and off mode power 

consumption into the combined metrics 

for dishwashers. 

For dehumidifiers, DOE is proposing 

in today’s NOPR to: 

(1) Establish a new measure of energy 

use to calculate the annual standby 

mode and off mode energy use in 

dehumidifiers, based on the typical 

hours dehumidifiers spend in these 

modes; and 

(2) Adopt a new measure of energy 

efficiency (integrated energy factor 

(IEF)) that includes energy used in 

standby, off, and active modes for 

dehumidifiers. 

For conventional cooking products, 

the current DOE test procedure accounts 

for energy used by a constant clock 

display (if present), which is considered 

as part of standby mode under the 

proposed definition of ‘‘standby mode.’’ 

The current test procedure also accounts 

for standby mode energy use of a 

continuously-burning pilot light for gas 

conventional cooking products.8

However, DOE proposes in today’s 

NOPR to amend the test procedure for 

conventional cooking products to fully 

account for all additional standby mode 

and off mode power consumption, as 

specified by provisions in IEC Standard 

62301. DOE proposes in today’s NOPR 

to: (1) Establish a new measure of 

energy use to calculate the annual 

standby mode and off mode energy 

consumption in conventional cooking 

products, and (2) adopt new measures of 

energy efficiency (IEF), annual energy 

consumption, and annual operating cost 

that include the energy used in all 

standby mode and off mode operations 

of conventional cooking products. In 

addition, DOE proposes additional 

clarifications to the testing methods for 

conventional cooking products to define 

the test duration for cases in which the 

measured power is not stable (i.e., varies 

over a cycle). DOE acknowledges that 

the power consumption of conventional 

cooking product displays can vary based 

on the clock time being displayed, so 

today’s proposal is drafted in a way to 

account for this fact, while still 

generating representative results. 

The statute also has other provisions 

regarding the inclusion of standby mode 

and off mode energy use in any energy 

conservation standard which have 

bearing on the current test procedure 

rulemaking. EPCA provides that 

amendments to the test procedures to 

include standby mode and off mode 

energy consumption shall not be used to 

determine compliance with product 

standards established prior to the 

adoption of the amended test 

procedures. (42 U.S.C. 6295(gg)(2)(C)) 

However, EPCA requires that DOE must 

determine to what extent, if any, the 

proposed test procedure would alter the 

measured energy efficiency, measured 

energy use, or measured water use 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 or 

measured energy use of a covered 

product, DOE must amend the 

applicable energy conservation standard 

during the rulemaking carried out with 

respect to the amended test procedure. 

In determining the amended energy 

conservation standard, the Secretary 

shall measure, pursuant to the amended 

test procedure, the energy efficiency, 

energy use, or water use of a 

representative sample of covered 

products that minimally comply with 

the existing standard. (42 U.S.C. 

6293(e)(2)) Although DOE remains 

obligated under 42 U.S.C. 6293(e)(1) to 

conduct an analysis of the impact of the 

test procedure amendments, 

amendments to the existing energy 

conservation standards are not required, 

because the statute already explicitly 

provides that the test procedure 

amendments for standby mode and off 

mode shall not apply to the energy 

conservation standards currently in 

place. The following discussion assesses 

these anticipated impacts, as well as the 

pathway for regulated entities to 

continue to be able to ascertain, certify, 

and report compliance with the existing 

standards until such time as amended 

standards are established which 

comprehensively address standby mode 

and off mode energy consumption. 

For dishwashers, the current energy 

conservation standards (10 CFR 

430.32(f)) are based on EAEU, which 

includes a simplified measure of 

standby mode power consumption. 

Because today’s proposed amendments 

would revise the calculations for EAEU 

and EAOC, both of which currently 

incorporate standby mode power, DOE 

investigated how the proposed 

amendments would affect the measured 

efficiency. As discussed in section III.G, 

DOE has tentatively determined that the 

proposed amendments in today’s NOPR 

would not measurably alter the 

measured efficiency of dishwashers. In 

addition, the proposed amendments 

would clarify that the amended 

calculations for EAEU need not be 

performed to demonstrate compliance 

with the existing energy conservation 

standards until the compliance date of 

amended energy conservation standards 

for dishwashers which take into account 

standby mode and off mode energy use. 

The proposed amendments would also 

require that any representations as to 

standby mode and off mode energy use 

must use the amended calculations for 

EAEU and EAOC on or after a date 180 

days after publication of the test 

procedure final rule. The amended test 

procedure, therefore, would still be able 

to be used by manufacturers to certify 

compliance of existing dishwashers 

with the current energy conservation 

standards. 

The current Federal energy 

conservation standards for 

dehumidifiers (10 CFR 430.32(v)), 

which are based on EF, do not currently 

account for standby mode or off mode 

power consumption. DOE proposes to 

establish a new integrated efficiency 

metric (integrated annual energy use) to 

account for standby mode and off mode 

power consumption. For this reason, the 

proposed amended test procedure 

would not alter the existing energy 

efficiency descriptor and, therefore, 

would not affect a manufacturer’s ability 

to demonstrate compliance with 

previously established standards for 

dehumidifiers. 

As noted earlier, the current energy 

conservation standards for cooking 

products (10 CFR 430.32(j)) require only 

that gas cooking products with an 

electrical supply cord not be equipped 

with a constant-burning pilot light. The 

same requirement applies to gas cooking 

products without an electrical supply 

cord, beginning on April 9, 2012. There 

are currently no performance-based 

Federal energy conservation standards 

for conventional cooking products 

(including energy use in standby mode 

and off mode). Thus, given the design 

standard currently in place, the 

proposed test procedure amendments 

would not alter one’s ability to comply 

with the existing energy conservation 

standard for cooking products. 

These amended test procedures 

would become effective in terms of 

adoption into the CFR, 30 days after the 

test procedure final rule is published in 

the Federal Register. However, DOE is 

proposing added language to the 

regulations codified in the CFR that 

would state that any added procedures 

and calculations for standby mode and 

off mode energy consumption resulting 

from implementation of the relevant 

provisions of EISA 2007 need not be 

performed at this time to determine 

compliance with the current energy 

conservation standards. Subsequently, 

manufacturers would be required to use 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 75295 

the amended test procedures’ standby 

mode and off mode provisions to 

demonstrate compliance with DOE’s 

energy conservation standards on the 

mandatory compliance date of a final 

rule establishing amended energy 

conservation standards for dishwasher, 

dehumidifier, and conventional cooking 

products that address standby mode and 

off mode energy consumption, at which 

time the limiting statements in the DOE 

test procedures would be removed. 

Further clarification would also be 

provided that as of 180 days after 

publication of a test procedure final 

rule, any representations related to the 

standby mode and off mode energy 

consumption of these products must be 

based upon results generated under the 

applicable provision of these test 

procedures. (42 U.S.C. 6293(c)(2)) 

As noted above, pursuant to its 

statutory mandate under 42 U.S.C. 

6295(gg)(2), DOE is only addressing 

issues related to standby mode and off 

mode energy use in the current test 

procedure rulemaking for residential 

dishwashers, dehumidifiers, and 

conventional cooking products. For 

issues that are determined to relate to 

active mode energy use for any of these 

products, DOE will consider such 

amendments in a future test procedure 

rulemaking under section 302 of EISA 

2007. Specifically, under that provision, 

DOE is required to review test 

procedures for covered products not 

later than every 7 years and to 

determine whether the test procedures 

accurately and fully comply with the 

requirement that they produce test 

results which are representative and not 

unduly burdensome to conduct. (42 

U.S.C. 6293(b)(1)) 

III. Discussion 

A. Products Covered by the Proposed 

Test Procedure Amendments 

Today’s proposed amendments to the 

DOE test procedures cover dishwashers, 

which DOE defines as follows: 

‘‘Dishwasher means a cabinet-like 

appliance which with the aid of water and 

detergent, washes, rinses, and dries (when a 

drying process is included) dishware, 

glassware, eating utensils, and most cooking 

utensils by chemical, mechanical and/or 

electrical means and discharges to the 

plumbing drainage system.’’ 10 CFR 430.2. 

Today’s proposed amendments to the 

DOE test procedures also cover 

dehumidifiers, which DOE defines as 

follows: 

‘‘Dehumidifier means a self-contained, 

electrically operated, and mechanically 

refrigerated encased assembly consisting of— 

(1) A refrigerated surface (evaporator) that 

condenses moisture from the atmosphere; 

(2) A refrigerating system, including an 

electric motor; 

(3) An air-circulating fan; and 

(4) Means for collecting or disposing of the 

condensate.’’ 

Id. 

Today’s proposed amendments to the 

DOE test procedures also cover cooking 

products, specifically conventional 

cooking products, which are defined as: 

‘‘Cooking products means consumer 

products that are used as the major 

household cooking appliances. They are 

designed to cook or heat different types of 

food by one or more of the following sources 

of heat: Gas, electricity, or microwave energy. 

Each product may consist of a horizontal 

cooking top containing one or more surface 

units and/or one or more heating 

compartments. They must be one of the 

following classes: Conventional ranges, 

conventional cooking tops, conventional 

ovens, microwave ovens, microwave/ 

conventional ranges and other cooking 

products.’’ 

* * * * * 

‘‘Conventional cooking top means a class of 

kitchen ranges and ovens which is a 

household cooking appliance consisting of a 

horizontal surface containing one or more 

surface units which include either a gas 

flame or electric resistance heating.’’ 

‘‘Conventional oven means a class of 

kitchen ranges and ovens which is a 

household cooking appliance consisting of 

one or more compartments intended for the 

cooking or heating of food by means of either 

a gas flame or electric resistance heating. It 

does not include portable or countertop 

ovens which use electric resistance heating 

for the cooking or heating of food and are 

designed for an electrical supply of 

approximately 120 volts.’’ 

‘‘Conventional range means a class of 

kitchen ranges and ovens which is a 

household cooking appliance consisting of a 

conventional cooking top and one or more 

conventional ovens.’’ 

Id. 

DOE is not proposing any 

amendments to these definitions in 

today’s notice. 

B. Incorporation by Reference of IEC 

Standard 62301 (First Edition) for 

Measuring Standby Mode and Off Mode 

Power Consumption 

As required by EPCA, as amended by 

EISA 2007, DOE considered the most 

current versions of IEC Standard 62301 

and IEC Standard 62087 for measuring 

power consumption in standby mode 

and off mode when developing today’s 

proposed amendments to the test 

procedures. (42 U.S.C. 6295(gg)(2)(A)) 

DOE notes that IEC Standard 62301 

includes provisions for measuring 

standby power in electrical appliances, 

and, thus, is relevant to this rulemaking. 

DOE also reviewed IEC Standard 62087, 

which specifies methods of measuring 

the power consumption of TV receivers, 

video cassette recorders (VCRs), set top 

boxes, audio equipment, and multifunction equipment for consumer use. 

IEC Standard 62087 does not, however, 

include methods for measuring the 

power consumption of electrical 

appliances such as dishwashers, 

dehumidifiers, or conventional cooking 

products. Therefore, DOE has 

tentatively determined that IEC 

Standard 62087 is unsuitable to this 

rulemaking and has not included any of 

its provisions in today’s proposed test 

procedure amendments. 

DOE proposes to incorporate by 

reference into these test procedures 

specific clauses from IEC Standard 

62301 (First Edition) for measuring 

standby mode and off mode power. 

Specifically, two clauses provide test 

conditions and test procedures for 

measuring the average standby mode 

and average off mode power 

consumption. Section 4 of IEC Standard 

62301 (First Edition) specifies test room 

conditions, supply voltage waveform, 

and power measurement meter 

tolerances, thereby ensuring repeatable 

and precise measurements of standby 

mode and off mode power consumption. 

Section 5 of IEC Standard 62301 (First 

Edition), regarding test procedures, 

specifies methods for measuring power 

consumption when it is stable and 

unstable (i.e., varies over a 

representative cycle). 

Specifically, DOE proposes to 

incorporate by reference into the DOE 

test procedures for dishwashers, 

dehumidifiers, and conventional 

cooking products the following 

provisions from IEC Standard 62301 

(First Edition):

4.5 Power measurement accuracy. 

5. Measurements ...................................................................................... 5.1 General, Note 1. 

5.2 Selection and preparation of appliance or equipment. 

5.3 Procedure. 

DOE notes that the current 

dishwasher test procedure already 

includes testing methods for measuring 

standby power consumption that are 

very similar to the provisions in IEC 

Standard 62301 (First Edition). 

However, DOE also notes that the 

current dishwasher test procedure does 

not contain provisions for measuring 

multiple standby modes or an off mode. 

EPCA, as amended by EISA 2007, 

requires DOE to amend its test 

procedures for all covered products to 

fully account for and incorporate 

standby mode and off mode energy 

consumption, and to consider the most 

current version of IEC Standard 62301 

as it does so. (42 U.S.C. 6295(gg)(2)(A)) 

As discussed below, DOE proposes to 

amend the dishwasher test procedure to 

include new definitions of ‘‘standby 

mode,’’ ‘‘off mode,’’ and ‘‘active mode’’ 

based on the provisions in IEC Standard 

62301 (FDIS). DOE also analyzed the 

current DOE dishwasher test procedure 

to determine if any other amendments 

would be necessary. The analysis has 

led DOE to tentatively conclude that the 

proposed clauses from IEC Standard 

62301 (First Edition) presented earlier 

would clarify the dishwasher testing 

procedure, as well as produce 

representative and repeatable test 

results. 

As discussed in Section I, the current 

DOE conventional cooking products test 

procedure does not fully account for 

standby mode and off mode energy 

consumption. The test procedure 

accounts only for the annual energy 

consumption of a continuouslyoperating clock, and the standby energy 

use associated with a continuouslyburning pilot light for gas cooking 

products. Otherwise, this test procedure 

does not address energy use in standby 

mode or off mode. For this reason, DOE 

has tentatively concluded that adopting 

the clauses from IEC Standard 62301 

(First Edition) as proposed would 

provide for a test procedure that would 

produce representative and repeatable 

test results that would fully account for 

standby mode and off mode energy 

consumption. 

As also discussed in section I, the 

current DOE dehumidifier test 

procedure does not contain any 

provisions for measuring energy use in 

standby mode or off mode. DOE has 

tentatively concluded that adopting the 

clauses from IEC Standard 62301 (First 

Edition) as proposed would provide for 

a test procedure that would produce 

representative and repeatable test 

results that would fully account for the 

standby mode and off mode energy 

consumption of dehumidifiers. 

DOE invites comment on whether IEC 

Standard 62301 (First Edition) can 

adequately measure standby mode and 

off mode power consumption for 

dishwashers, dehumidifiers, and 

conventional cooking products, and 

whether these specific provisions 

should be incorporated into the test 

procedures. 

DOE is aware that the EPCA 

requirement to consider IEC Standard 

62301 in developing amended test 

procedures to include standby mode 

and off mode power consumption 

results in a potential conflict between 

the EPCA and IEC Standard 62301 

(FDIS) definitions of ‘‘standby mode.’’ 

EPCA defines ‘‘standby mode’’ as the 

condition in which a product is 

connected to a main power source and 

offers one or more of the following useroriented or protective functions: (1) To 

facilitate the activation or deactivation 

of other functions (including active 

mode) by remote switch (including 

remote control), internal sensor, or 

timer; and/or (2) to provide continuous 

functions, including information or 

status displays (including clocks) or 

sensor-based functions. (42 U.S.C. 

6295(gg)(1)(A)(iii)) However, paragraph 

3.1 of the IEC Standard 62301 (First 

Edition) defines ‘‘standby mode’’ as the 

‘‘lowest power consumption mode 

which cannot be switched off 

(influenced) by the user and that may 

persist for an indefinite time when an 

appliance is connected to the main 

electricity supply and used in 

accordance with the manufacturer’s 

instructions.’’ Finally, DOE adopted a 

third definition prior to EISA 2007 for 

‘‘standby mode’’ nearly identical to that 

of IEC Standard 62301 (First Edition) in 

the dishwasher test procedure, in which 

‘‘standby mode’’ ‘‘means the lowest 

power consumption mode which cannot 

be switched off or influenced by the 

user and that may persist for an 

indefinite time when the dishwasher is 

connected to the main electricity supply 

and used in accordance with the 

manufacturer’s instructions.’’ (10 CFR 

part 430, subpart B, appendix C, section 

1.14) However, DOE is free to resolve 

any such conflict, because EISA 2007 

specifically grants authority to amend 

the statutory definitions of ‘‘active 

mode,’’ ‘‘off mode,’’ and ‘‘standby mode.’’ 

(42 U.S.C. 6295(gg)(1)(B)) DOE notes 

that the statute requires consideration of 

the most current version of IEC 

Standard 62301, but it does not require 

its adoption if DOE determines that 

another definition(s) would be more 

appropriate. 

Although 42 U.S.C. 6295(gg)(2)(A) 

requires that DOE consider the most 

current version of IEC Standard 62301, 

DOE notes that the IEC is developing an 

updated version of this standard, IEC 

Standard 62301 (Second Edition). This 

updated version of IEC Standard 62301 

is expected to include definitions of ‘‘off 

mode,’’ ‘‘network mode,’’ and 

‘‘disconnected mode,’’ and it would also 

revise the current IEC Standard 62301 

(First Edition) definition of ‘‘standby 

mode.’’ However, the IEC anticipates 

that the final version of IEC Standard 

62301 (Second Edition) will likely be 

published only in late 2010 at the 

earliest. Therefore, for this proposed 

rule, the second edition is not available 

for DOE’s consideration or 

incorporation by reference. Thus, IEC 

Standard 62301 (First Edition) is the 

‘‘current version’’ for purposes of 42 

U.S.C. 6295(gg)(2)(A). 

DOE is aware that there are significant 

differences between IEC Standard 62301 

(First Edition) and IEC Standard 62301 

(FDIS), which is the latest draft version 

of IEC Standard 62301 (Second Edition). 

For example, IEC Standard 62301 (FDIS) 

clarifies certain provisions, such as 

clarifying the definition of ‘‘standby 

mode’’ and ‘‘off mode’’ to allow for the 

measurement of multiple standby power 

modes. 

DOE has reviewed IEC Standard 

62301 (FDIS) and anticipates that, once 

finalized, it will ultimately define the

Measurement of standby power’’ (August 7, 2009) 

p. 6. IEC Standards are available online at http:// 

www.iec.ch. 

various modes differently than IEC 

Standard 62301 (First Edition). IEC 

Standard 62301 (FDIS) incorporates 

responses to comments from multiple 

national committees from member 

countries on several previous draft 

versions, and thus, DOE believes, it 

provides the best available mode 

definitions. Although the revised IEC 

Standard 62301 (Second Edition) has 

not yet been officially released, DOE has 

decided to consider the substance of the 

new operational mode definitions from 

the draft version IEC Standard 62301 

(FDIS). DOE notes that the mode 

definitions in IEC Standard 62301 

(FDIS) are substantively similar to those 

in the previous draft version (IEC 

Standard 62301 (CDV)), which were the 

subject of extensive comments from 

interested parties during recent DOE test 

procedure rulemakings addressing 

standby mode and off mode energy use 

in other products (i.e., microwave 

ovens, clothes dryers, and room air 

conditioners). In those instances, 

interested parties indicated general 

support for adopting the mode 

definitions provided in IEC Standard 

62301 (CDV). Due to the effective 

equivalence of the mode definitions in 

IEC Standard 62301 (CDV) and IEC 

Standard 62301 (FDIS), DOE believes 

the public comment support expressed 

for the mode definitions in IEC Standard 

62301 (CDV) would extend to those in 

IEC Standard 62301 (FDIS). 

DOE notes that other significant 

changes in the methodology were first 

introduced only at the IEC Standard 

62301 (FDIS) stage. These changes have 

not been the subject of significant public 

comment from interested parties, nor 

has DOE had the opportunity to conduct 

a thorough analysis of those provisions. 

Consequently, the merits of these latest 

changes have not been fully vetted, as 

would demonstrate that they are 

preferable to the existing 

methodological provisions in the 

current version of the IEC standard. 

Thus, DOE is not able to determine 

whether the updated methodology 

represents the best available means to 

measure standby mode and off mode 

energy use, so DOE has tentatively 

decided to base the proposed test 

procedure amendments (other than the 

mode definitions previously discussed) 

on the provisions of IEC Standard 62301 

(First Edition). 

After considering the most current 

version of IEC Standard 62301 (i.e., the 

First Edition) and the draft version of 

IEC Standard 62301 (i.e., FDIS), DOE 

has tentatively concluded that the 

definitions of ‘‘standby mode,’’ ‘‘off 

mode,’’ and ‘‘active mode’’ provided in 

IEC Standard 62301 (FDIS) are the most 

useful, in that they expand upon the 

EPCA mode definitions and provide 

additional guidance as to which 

functions are associated with each 

mode. Therefore, DOE is proposing 

definitions of ‘‘standby mode,’’ ‘‘off 

mode,’’ and ‘‘active mode’’ based on the 

definitions provided in IEC Standard 

62301 (FDIS). These definitions are 

discussed in detail immediately below 

in section III.C. 

C. Determination and Classification of 

Operational Modes 

As stated earlier, without further 

clarification, regulated parties’ attempts 

to reconcile differences between the 

mode definitions specified by EPCA and 

IEC Standard 62301 (First Edition) 

could lead to multiple interpretations. 

Therefore, DOE is proposing regulatory 

definitions for these key terms in order 

to ensure consistent application of the 

test procedure provisions related to 

standby mode and off mode. This 

section first discusses these overarching 

definitional changes and then follows 

with a product-specific analysis of 

different operational modes in order to 

determine whether they are active 

mode, standby mode, or off mode 

functions. DOE’s proposed approach is 

set forth below. 

EPCA defines ‘‘active mode’’ as the 

condition in which an energy-using 

product: 

(1) Is connected to a main power 

source; 

(2) Has been activated; and 

(3) Provides one or more main 

functions. 

(42 U.S.C. 6295(gg)(1)(A)(i)) 

EPCA defines ‘‘standby mode’’ as the 

condition in which an energy-using 

product: 

(1) Is connected to a main power 

source; and 

(2) Offers one or more of the following 

user-oriented or protective functions: 

(a) To facilitate the activation or 

deactivation of other functions 

(including 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. 

(42 U.S.C. 6295(gg)(1)(A)(iii)) 

This definition of ‘‘standby mode’’ 

differs from the one provided in IEC 

Standard 62301 (First Edition) by 

permitting the inclusion of multiple 

standby modes. 

EPCA defines ‘‘off mode’’ as the 

condition in which an energy-using 

product: 

(1) Is connected to a main power 

source; and 

(2) Is not providing any standby mode 

or active mode function. 

(42 U.S.C. 6295(gg)(1)(A)(ii)) 

DOE recognizes that the EPCA 

definitions for ‘‘active mode,’’ ‘‘standby 

mode,’’ and ‘‘off mode’’ were developed 

to be broadly applicable for many 

energy-using products. For specific 

products with multiple functions, these 

broad definitions could lead to multiple 

interpretations. Therefore, DOE 

proposes to amend the test procedures 

to include definitions for these modes 

based on the definitions provided in IEC 

Standard 62301 (FDIS), with added 

provisions specific to dishwashers, 

dehumidifiers, and conventional 

cooking products. DOE’s proposed 

approach is discussed below. 

DOE proposes to define ‘‘active mode’’ 

for dishwashers, dehumidifiers, and 

conventional cooking products as the 

condition in which the energy-using 

product is connected to a mains power 

source, has been activated, and provides 

one or more main functions. DOE notes 

that section 3.8 of IEC Standard 62301 

(Second Edition Committee Draft 2) (IEC 

Standard 62301 (CD2)) provides the 

additional clarification that ‘‘delay start 

mode is a one off user initiated short 

duration function that is associated with 

an active mode.’’ The subsequent IEC 

Standard 62301 Committee Draft for 

Vote (IEC Standard 62301 (CDV)) 

removed this clarification based on a 

comment from a member committee on 

IEC Standard 62301 (CD2) that the 

clarification conflicted with the 

proposed definition of ‘‘standby mode,’’ 

which would include ‘‘activation of 

* * * active mode by * * * timer.’’ 

However, in its response to that 

comment, the IEC reiterated that delay 

start mode is a one-off function of 

limited duration, even though it took 

action to delete the clarification in IEC 

Standard 62301 (CDV).9 DOE infers this 

to mean that delay start mode should, 

therefore, be considered part of active 

mode. However, DOE notes that IEC 

Standard 62301 (FDIS) classifies delay 

start as a secondary function and not 

part of active mode. DOE continues to 

believe, however, that because delay 

start is of limited duration and is 

uniquely associated with the initiation 

of a main function, it should be 

considered part of active mode. 

Additional discussion of delay start 

mode is provided later in this section. 

DOE also proposes the following 

clarifications for the range of main

10The actual language for the ‘‘standby mode’’ 

definition in IEC Standard 62301 (FDIS) describes 

‘‘* * * user oriented or protective functions which 

usually persist’’ rather than ‘‘* * * user oriented 

or protective functions which may persist for an 

indefinite time.’’ DOE notes, however, that section 

5.1 of IEC Standard 62301 (FDIS) states that ‘‘a 

mode is considered to be persistent where the 

power level is constant or where there are several 

power levels that occur in a regular sequence for an 

indefinite period of time.’’ DOE believes that the 

proposed language, which was originally included 

in IEC Standard 62301 (CD2), encompasses the 

possible scenarios foreseen by section 5.1 of IEC 

Standard 62301 (FDIS) without unnecessary 

specificity. 

functions that would be classified as 

active mode for each product: 

Dishwashers—‘‘Active mode’’ means a 

mode in which the dishwasher is performing 

the main function of washing, rinsing, or 

drying (when a drying process is included) 

dishware, glassware, eating utensils, and 

most cooking utensils by chemical, 

mechanical and/or electrical means, or is 

involved in functions necessary for these 

main functions, such as admitting water into 

the dishwasher or pumping water out of the 

dishwasher. 

Conventional Cooking Products—‘‘Active 

mode’’ means a mode in which a 

conventional cooking top, conventional oven, 

or conventional range is performing the main 

function of cooking, heating, proofing, or 

holding the cooking load by means of either 

a gas flame or electric resistance heating. 

Dehumidifiers—‘‘Active mode’’ means a 

mode in which a dehumidifier is performing 

the main functions of removing moisture 

from ambient air by drawing moist air over 

a refrigerated coil using a fan, circulating air 

through activation of the fan without 

activation of the refrigeration system, or 

defrosting the refrigerant coil. 

DOE proposes to define ‘‘standby 

mode’’ for dishwashers, dehumidifiers, 

and conventional cooking products as 

any mode in which the product is 

connected to a mains power source and 

offers one or more of the following useroriented or protective functions which 

may persist for an indefinite time: 10

• To facilitate the activation of other 

modes (including activation or 

deactivation of active mode) by remote 

switch (including remote control), 

internal sensor, or timer; 

• Continuous functions, including 

information or status displays 

(including clocks) or sensor-based 

functions. 

DOE proposes the additional 

clarification that a timer is a continuous 

clock function (which may or may not 

be associated with a display) that 

provides regular scheduled tasks (e.g., 

switching) and that operates on a 

continuous basis. As noted in section 

III.B, this definition of ‘‘standby mode’’ 

is based on the definitions provided in 

IEC Standard 62301 (FDIS), and 

expands upon the EPCA mode 

definitions to provide additional 

clarifications as to which functions are 

associated with each mode. 

As noted earlier, the current DOE 

dishwasher test procedure defines 

‘‘standby mode’’ as the lowest power 

consumption mode that cannot be 

switched off or influenced by the user 

and that may persist for an indefinite 

time when the dishwasher is connected 

to the main electricity supply and used 

in accordance with manufacturer’s 

instructions. That definition is 

comparable to the definition in IEC 

Standard 62301 (First Edition). DOE 

believes that the proposed ‘‘standby 

mode’’ definition based on IEC Standard 

62301 (FDIS) is preferable in that it 

expands upon the definition in IEC 

Standard 62301 (First Edition) and 

provides additional guidance as to what 

functions are associated with standby 

mode. For this reason, DOE proposes in 

today’s NOPR to amend the ‘‘standby 

mode’’ definition in the dishwasher test 

procedure based on the definition 

provided in IEC Standard 62301 (FDIS). 

Furthermore, DOE proposes to 

redesignate the current DOE definition 

as a ‘‘simplified standby mode’’ in order 

to allow manufacturers to continue to 

use the existing standby mode 

provisions to determine compliance 

with the current dishwasher energy 

conservation standards until such time 

as these standards are amended to 

address standby mode and off mode 

energy use. 

DOE proposes to define ‘‘inactive 

mode’’ for dishwashers, dehumidifiers, 

and conventional cooking products as a 

standby mode that facilitates the 

activation of active mode by remote 

switch (including remote control), 

internal sensor, or timer, or that 

provides continuous status display. 

The following discussion analyzes 

various product-specific modes for 

dishwashers, dehumidifiers, and 

conventional cooking products to 

determine whether they would be 

properly characterized as active mode, 

standby mode, or off mode functions. 

1. Dishwashers 

DOE is aware of two additional 

relevant modes for dishwashers: 

(1) delay start mode; and (2) cycle 

finished mode. ‘‘Delay start mode’’ is 

defined as a mode in which activation 

of an active mode is facilitated by a 

timer. ‘‘Cycle finished mode’’ is defined 

as a mode that provides continuous 

status display following operation in 

active mode. As discussed earlier, 

because delay start mode is not a mode 

that may persist for an indefinite time, 

DOE believes that delay start mode 

would not be considered part of standby 

mode, but instead would be a form of 

active mode. DOE is not proposing 

amendments to the dishwasher test 

procedure to define ‘‘delay start mode’’ 

or to measure power consumption in 

this mode. DOE may consider 

amendments addressing delay start 

mode issues in a future dishwasher test 

procedure rulemaking conducted under 

the 7-year schedule requirements of the 

EISA 2007 amendments to EPCA. (42 

U.S.C. 6293(b)(1)) 

Based on the proposed ‘‘standby 

mode’’ definition, cycle finished mode, 

a mode that provides a continuous 

status display and may persist for an 

indefinite time, would be considered as 

part of a standby mode. Therefore, DOE 

proposes in today’s NOPR to define 

cycle finished mode for dishwashers as 

‘‘a mode which provides continuous 

status display following operation in 

active mode.’’ Proposed provisions to 

measure energy use in delay start mode 

and cycle finished mode are discussed 

in section III.E.1. 

2. Dehumidifiers 

DOE is aware of three additional 

relevant modes for dehumidifiers: 

(1) Delay start mode; (2) off-cycle mode; 

and (3) bucket full/removed mode. The 

definition for ‘‘delay start mode’’ for 

dehumidifiers is the same as that for 

dishwashers. ‘‘Off-cycle mode’’ is 

defined as a mode in which a 

dehumidifier has cycled off its main 

function by humidistat or humidity 

sensor, does not have its fan or blower 

operating, and will reactivate the main 

function according to the humidistat or 

humidity sensor signal. ‘‘Bucket full/ 

removed mode’’ is defined as a mode in 

which the dehumidifier has 

automatically powered off its main 

function by detecting when the water 

collection bucket is full or has been 

removed. For the same reasons 

discussed earlier for dishwashers, DOE 

believes that delay start mode would not 

be considered a standby mode, but 

instead would be a form of active mode. 

Therefore, DOE is not proposing 

amendments to define or to measure 

power consumption in ‘‘delay start 

mode.’’ DOE may consider amendments 

addressing delay start mode issues in a 

future dehumidifier test procedure 

rulemaking conducted under the 7-year 

schedule requirements of the EISA 2007 

amendments to EPCA. (42 U.S.C. 

6293(b)(1)) 

DOE believes that off-cycle mode and 

bucket full/removed mode are modes 

that may persist for an indefinite time 

and, under the proposed definition, 

would be considered as part of standby 

mode. Therefore, DOE proposes 

amending its dehumidifier test 

procedure to include definitions of ‘‘offVerDate Mar<15>2010 17:04 Dec 01, 2010 Jkt 223001 PO 00000 Frm 00010 Fmt 4701 Sfmt 4702 E:\FR\FM\02DEP3.SGM 02DEP3

cycle mode’’ and ‘‘bucket full/removed 

mode.’’ Proposed provisions to measure 

energy use in delay start mode, off-cycle 

mode, and bucket full/removed mode 

are discussed in section III.E.2. 

3. Conventional Cooking Products 

DOE is aware of three additional 

relevant modes for conventional 

cooking products: (1) Delay start mode; 

(2) cycle finished mode; and (3) Sabbath 

mode. ‘‘Delay start mode’’ and ‘‘cycle 

finished mode’’ are defined as for 

dishwashers. ‘‘Sabbath mode’’ is defined 

as a mode in which the automatic 

shutoff is overridden to allow for 

warming of pre-cooked foods during 

such periods as the Jewish Sabbath. For 

the same reasons as discussed for 

dishwashers and dehumidifiers, DOE 

believes that delay start mode would not 

be considered a standby mode, but 

instead would be a form of active mode. 

Therefore, DOE is not proposing 

amendments to define or to measure 

power consumption in ‘‘delay start 

mode.’’ In addition, DOE believes that 

the Sabbath mode function of warming 

food would also be considered part of 

the active mode. Therefore, DOE is not 

proposing amendments to define or to 

measure power consumption in 

‘‘Sabbath mode.’’ DOE may consider 

amendments addressing delay start 

mode and Sabbath mode issues in a 

future cooking products test procedure 

rulemaking conducted under the 7-year 

schedule requirements of the EISA 2007 

amendments to EPCA. (42 U.S.C. 

6293(b)(1)) 

DOE believes that cycle finished 

mode is a mode that may persist for an 

indefinite time and, under the proposed 

definition, would be considered as part 

of standby mode. Therefore, DOE 

proposes to amend its conventional 

cooking products test procedure to 

include a definition of ‘‘cycle finished 

mode.’’ Proposed provisions to measure 

energy use in delay start mode and cycle 

finished mode are discussed in section 

III.E.3. 

As discussed in section III.B, DOE 

proposes to amend the test procedures 

for residential dishwashers, 

dehumidifiers, and conventional 

cooking products to define ‘‘off mode’’ as 

a mode in which the product is 

connected to a mains power source and 

is not providing any active mode or 

standby mode function, and where the 

mode may persist for an indefinite time. 

An indicator that shows the user only 

that the product is in the off positions 

is included within the classification of 

off mode. As noted in section III.B, this 

definition of ‘‘off mode’’ is based on the 

definitions provided in IEC Standard 

62301 (FDIS) and is useful in terms of 

expanding the scope of the EPCA mode 

definitions to clarify which functions 

are associated with off mode. 

Under the proposed definitions, a 

dishwasher, dehumidifier, or 

conventional cooking product equipped 

with a mechanical on/off switch that 

can disconnect power to the display 

and/or control components would be 

considered as operating in the off mode 

when the switch is in the ‘‘off’’ position, 

provided that no other standby mode or 

active mode functions are energized. An 

energized light-emitting diode (LED) or 

other indication that shows the user 

only that the product is in the off 

position would be considered part of off 

mode under the proposed definition, 

again provided that no other standby 

mode or active mode functions are 

energized. However, if any energy is 

consumed by the appliance in the 

presence of a one-way remote control, 

the unit would be considered to be 

operating in standby mode because the 

remote control would be used to 

activate or deactivate other mode(s). 

Electrical leakage and any energy 

consumed for electrical noise reduction, 

which are not specifically categorized as 

standby power functions, would be 

indicative of off mode and would be 

measured by the proposed amended test 

procedures. 

Section 3.7 of IEC Standard 62301 

(FDIS) also defines ‘‘network mode’’ as a 

mode category that includes ‘‘any 

product modes where the energy using 

product is connected to a mains power 

source and at least one network function 

is activated (such as reactivation via 

network command or network integrity 

communication) but where the primary 

function is not active.’’ Section 3.7 of 

IEC Standard 62301 (FDIS) also 

provides a note, stating that ‘‘[w]here a 

network function is provided but is not 

active and/or not connected to a 

network, then this mode is not 

applicable. A network function could 

become active intermittently according 

to a fixed schedule or in response to a 

network requirement. A ‘network’ in 

this context includes communication 

between two or more separately 

independently powered devices or 

products. A network does not include 

one or more controls which are 

dedicated to a single product. Network 

mode may include one or more standby 

functions.’’ 

DOE acknowledges that in the future, 

products that are the subject of this 

rulemaking could incorporate a network 

mode for either communication with 

technicians for repair and performance 

monitoring, or for interaction with the 

electric grid. At this time, however, DOE 

is unaware of any data that would 

enable it to determine appropriate 

testing procedures and mode definitions 

for incorporation into test procedures 

for network mode in dishwashers, 

dehumidifiers, and conventional 

cooking products. This makes it 

extremely difficult to consider 

evaluation of a networked unit, even in 

terms of categorizing it as a standby 

mode or off mode function. In 

particular, DOE is unaware of methods 

for appropriately configuring networks 

or methods for collecting data about the 

energy use of appropriately configured 

networks. DOE also has no information 

as to whether network connection speed 

or the number and type of network 

connections affect power consumption 

for these products. DOE also has no 

information as to whether wireless 

network devices in such products 

would have different levels of power 

consumption when a device is looking 

for a connection versus when the 

network connection is established. DOE 

is also unaware of how the energy 

consumption for dishwashers, 

dehumidifiers, and conventional 

cooking products in a network 

environment may be affected by their 

product design and user interaction, as 

well as network interaction. These 

effects would need to be measured both 

if the network function could become 

active intermittently according to a 

fixed schedule or in response to a 

network requirement. For these reasons, 

the amendments proposed in today’s 

NOPR do not include provisions for 

testing network mode energy 

consumption in dishwashers, 

dehumidifiers, and conventional 

cooking products. Provisions for testing 

power consumption in network mode 

could be incorporated into the test 

procedure through future amendments 

once the appropriate data and testing 

methodologies become available. DOE 

welcomes comment on whether 

dishwashers, dehumidifiers, or 

conventional cooking products that 

incorporate a networking function are 

currently available, and whether 

definitions and testing procedures for a 

network mode should be incorporated 

into the DOE test procedures. DOE also 

requests comment on appropriate 

testing methodologies for measuring 

energy consumption in a network mode 

for dishwashers, dehumidifiers, and 

conventional cooking products, and 

data on the repeatability of those testing 

methodologies. 

DOE also notes that section 3.9 of IEC 

Standard 62301 (FDIS) provides a 

definition for ‘‘disconnected mode,’’ 

which is ‘‘the state where all 

connections to mains power sources of 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
75300 Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 

the energy using product are removed or 

interrupted.’’ IEC Standard 62301 (FDIS) 

also adds a note that common terms 

such as ‘‘unplugged’’ or ‘‘cut off from 

mains’’ also describe this mode and that 

this mode is not part of off mode, 

standby mode, or network mode. DOE 

believes that there would be no energy 

use in a disconnected mode and agrees 

that it would not be part of off mode, 

standby mode, or network mode. 

Therefore, DOE is not proposing a 

definition or testing method for 

disconnected mode in the test 

procedures for residential dishwashers, 

dehumidifiers, or conventional cooking 

products. 

D. Specifications for the Test Methods 

and Measurements for Standby Mode 

and Off Mode Testing 

DOE proposes amending its test 

procedures to include provisions for 

measuring the power consumption of 

dishwashers, dehumidifiers, and 

conventional cooking products in all 

standby and off modes. This section first 

discusses issues relevant to all three 

types of products subject to this 

rulemaking, and then, it subsequently 

addresses issues specific to each 

product type. As an initial matter, DOE 

would clarify the provisions it proposes 

to include in the test procedures to 

clarify the IEC Standard 62301 (First 

Edition) methods when used to measure 

standby mode and off mode energy use 

in dishwashers, dehumidifiers, and 

conventional cooking products. These 

proposed amendments also include 

provisions for measuring energy use in 

cycle finished mode for dishwashers, 

off-cycle mode and bucket full/removed 

mode for dehumidifiers, and cycle 

finished mode for conventional cooking 

products. 

For all three products, DOE is 

proposing a test method based on the 

provisions from IEC Standard 62301 

(First Edition). Paragraph 5.3.1 of IEC 

Standard 62301 (First Edition) specifies 

the following test method for products 

in which the power varies by not more 

than 5 percent from a maximum level 

during a period of 5 minutes: (1) Wait 

at least 5 minutes after selecting the 

mode to be measured for the product to 

stabilize; and (2) measure the power 

consumption at the end of an additional 

time period of not less than 5 minutes. 

IEC Standard 62301 (First Edition), 

paragraph 5.3.2, contains provisions for 

measuring average power in cases where 

the power is not stable (i.e., the 

measured power varies by more than 5 

percent from a maximum level during a 

period of 5 minutes). Such instances can 

include, for example, a clock display 

whose power consumption varies as a 

function of the time displayed or 

internal electronic components which 

are cycled on and off regularly. In such 

cases, IEC Standard 62301 (First 

Edition) requires a measurement period 

of no less than 5 minutes, or, if there is 

an operating cycle (defined as a regular 

sequence of power states that occur over 

several minutes or hours), one or more 

complete cycles. DOE notes these 

provisions do not preclude 

manufacturers from testing products 

with a longer stabilization period, or a 

longer measurement period, as long as 

the power does not vary by more than 

5 percent or the stabilization period 

represents one or more complete cycles. 

DOE expects results obtained under 

such conditions would be comparable to 

those obtained using the minimum 

allowable stabilization and 

measurement periods. 

DOE is aware that residential 

dishwashers and conventional cooking 

products with displays may reduce 

power consumption by dimming after a 

period of user inactivity (known as 

‘‘automatic power-down’’). For products 

whose power consumption in inactive 

mode varies in this manner during 

testing, DOE proposes that the test be 

conducted after the power level has 

dropped to its lowest level, as discussed 

in IEC Standard 62301 (First Edition), 

section 5, paragraph 5.1, Note 1. DOE 

believes that products with automatic 

power-down spend more time in this 

low-power state than in the higherpower state. Thus, the energy 

consumption at the low-power level is 

most representative of inactive mode 

power range. 

DOE is aware that IEC Standard 62301 

(First Edition) does not provide 

guidance on how long to wait for the 

appliance to drop to the lower-power 

state. DOE tested 14 dishwashers, 13 

dehumidifiers, and 41 conventional 

cooking products and observed that 

units with an automatic power-down 

feature persisted in the higher-power 

state for less than 10 minutes of user 

inactivity after the display has initially 

been energized. However, the test 

sample was small and may not be 

sufficiently representative. It is possible 

that some dishwashers, dehumidifiers, 

and conventional cooking products may 

remain in the higher-power state for the 

duration of a 5-minute stabilization 

period and subsequent 5-minute 

measurement period, and then drop to 

the lower-power state that is more 

representative of inactive mode. In 

contrast, IEC Standard 62301 (CDV) 

specifies for each testing method that 

the product shall be allowed to stabilize 

for at least 30 minutes prior to a 

measurement period of not less than 10 

minutes. DOE believes this specification 

would allow sufficient time for all 

displays that automatically dim or 

power down after a period of user 

inactivity to reach the lower-power state 

prior to measurement. DOE believes that 

the IEC Standard 62301 (CDV) 30- 

minute stabilization and 10-minute 

measurement periods provide a clearer 

and more consistent testing procedure 

than the corresponding time periods 

specified in IEC Standard 62301 (First 

Edition). Those periods allow for 

representative measurements to be made 

among products that may have varying 

time periods before the power drops to 

a lower level more representative of 

standby mode, off mode, or cycle 

finished mode. 

DOE notes that IEC Standard 62301 

(FDIS) establishes an overall test period 

of not less than 15 minutes for products 

in which power consumption in the 

mode being tested is not cyclic. Data 

collected during the first third of the 

total period are discarded (and, thus, 

this time could be inferred to be a 

stabilization period), and data from the 

remaining two-thirds of the total period 

are used to determine whether the 

power is stable. If stability is not 

achieved, the total period is extended 

continuously until the stability criteria 

are achieved, to a maximum of 3 hours. 

Modes that are known to be non-cyclic 

and of varying power consumption shall 

follow this same procedure, but with a 

total test period not less than 60 

minutes. If power consumption in a 

mode is cyclic, measurements must be 

conducted with an initial operation 

period (analogous to a stabilization 

period) of at least 10 minutes, and the 

average power measured over at least 

four complete cycles. The measurement 

period must be at least 20 minutes. After 

careful consideration, DOE has 

tentatively concluded that the 

specifications provided in IEC Standard 

62301 (FDIS) would not produce power 

consumption measurements as accurate, 

repeatable, and enforceable as the 

specifications provided in IEC Standard 

62301 (CDV). Therefore, DOE proposes 

to require that dishwashers, 

dehumidifiers, and conventional 

cooking products be allowed to stabilize 

for at least 30 minutes prior to a power 

measurement period of not less than 10 

minutes. (For the reasons discussed in 

section III.D.3, DOE is proposing a 

choice between different methodologies 

for the specific case in which 

conventional cooking product energy 

use in standby mode varies as a function 

of the time displayed on a clock. In such 

case, DOE proposes to specify setting 

the clock to a particular start time at the

end of a 10-minute stabilization period, 

waiting another 10 minutes for the 

product again to stabilize, and then 

measuring standby power over a period 

of 10 minutes. Alternatively, DOE 

proposes that manufacturers, at their 

own discretion, may choose to measure 

standby power over a 12-hour period 

that captures all possible variations of 

power consumption as a function of the 

time displayed.) Although DOE did not 

observe any dehumidifiers with 

displays that automatically powered 

down, DOE is proposing the 30-minute 

stabilization and 10-minute power 

measurement periods for those products 

as well in order to account for currently 

available or future models that may 

have such a feature. 

DOE’s test procedures are developed 

to measure representative energy use for 

the typical consumer and cannot 

capture all possible consumer actions 

and appliance usage patterns that might 

increase energy use. For example, 

certain products featuring a display 

power-down may allow consumers to 

alter the display settings to increase the 

amount of time in the high-power state, 

or to make the high-power state 

permanent. However, DOE believes the 

typical consumer will not alter the 

standard or default settings. Therefore, 

DOE has not proposed additional 

provisions in today’s NOPR to address 

the possibility of increased energy use 

as a result of consumers adjusting the 

display power-down settings or other 

features. DOE welcomes comment on 

the suitability of using the default 

settings in testing standby mode energy 

consumption. It also welcomes 

comment on any testing methodologies 

that can account for consumer actions 

that might increase energy use, and 

requests data on the repeatability of 

those testing methodologies. 

The following sections describe the 

proposed test method that is specific to 

each of the three products that are the 

subject of this rulemaking. 

1. Dishwashers 

DOE proposes that test room ambient 

temperatures for standby mode and off 

mode testing be specified for all 

dishwashers according to section 4, 

paragraph 4.2 of IEC Standard 62301 

(First Edition). The IEC standard 

specifies a temperature range of 73.4 

± 9 °F. The current DOE test procedure 

for dishwashers includes a test room 

ambient air temperature requirement of 

75 ± 5 °F. The narrower range of 

allowable ambient temperature in the 

DOE test procedure helps ensure 

consistent and repeatable test results for 

active mode measurements in which 

heat losses could affect energy 

consumption, but energy use in standby 

mode or off mode are less affected by 

ambient temperature. Today’s proposed 

test procedure would allow 

manufacturers of dishwashers to use the 

more stringent ambient temperature 

range in the current DOE test procedure 

if tests of active mode efficiency 

performance and standby mode and off 

mode power consumption are 

conducted simultaneously in the same 

room on multiple dishwashers. 

Alternatively, the proposed temperature 

specifications taken from IEC Standard 

62301 (First Edition) would allow a 

manufacturer that opts to conduct 

standby mode and off mode testing 

separately from active mode testing 

more latitude in maintaining ambient 

conditions. DOE requests comment on 

the appropriateness of this proposed 

modified test room ambient temperature 

range. 

2. Dehumidifiers 

DOE proposes that test room ambient 

temperatures for standby mode and off 

mode testing be specified for all 

dehumidifiers according to section 4, 

paragraph 4.2 of IEC Standard 62301 

(First Edition). The IEC standard 

specifies a temperature range of 73.4 

± 9 °F. The current DOE test procedure 

for dehumidifiers references the 

ENERGY STAR test criteria for 

dehumidifiers. The ENERGY STAR test 

criteria are based on ANSI/AHAM 

Standard DH–1–2003, ‘‘Dehumidifiers,’’ 

which specifies a test room ambient 

temperature of 80 ± 2 °F for testing. 

Today’s proposed test procedure would 

allow manufacturers of dehumidifiers to 

conduct active mode efficiency 

performance testing and standby mode 

and off mode power consumption 

testing simultaneously in the same room 

on multiple dehumidifiers, as long as 

the temperature requirements for both 

tests are met. Alternatively, the 

proposed temperature specifications 

taken from IEC Standard 62301 (First 

Edition) would allow a manufacturer 

that opts to conduct standby mode and 

off mode testing separately from 

performance testing to use the ambient 

temperature requirement of 73.4 ± 9 °F. 

DOE requests comment on the 

appropriateness of this proposed 

modified test room ambient temperature 

range. 

DOE also proposes additional 

clarifications to the power supply 

requirements for standby mode and off 

mode testing for dehumidifiers to 

require that the power supply frequency 

be the rated frequency ± 1 percent. The 

current DOE dehumidifier test 

procedure requires that the power 

supply for the active mode test have a 

supply voltage of 115/230 volts (V) ± 2 

percent (depending on the voltage 

specified on the name plate), and be at 

the rated frequency (no allowable range 

is specified for the latter). DOE notes 

that section 4, paragraph 4.3 of IEC 

Standard 62301 (First Edition) states 

that when IEC Standard 62301 is 

referenced by an external standard, the 

test voltage and frequency defined by 

the external standard shall be used. 

When the test voltage and frequency are 

not defined by the external standard, 

IEC Standard 62301 (First Edition) 

requires that the supply voltage and 

frequency be 115 V ± 1 percent and 60 

Hertz (Hz) ± 1 percent, respectively. 

Because the current DOE dehumidifier 

test procedure specifies that the rated 

frequency be used for testing but does 

not provide an allowable range, DOE 

proposes that the range of ± 1 percent 

specified by IEC Standard 62301 (First 

Edition) be used for standby mode and 

off mode testing. DOE requests 

comments on its proposed amendments 

related to frequency. 

3. Conventional Cooking Products 

DOE proposes that test room ambient 

temperatures for standby mode and off 

mode testing be specified for all 

conventional cooking products, 

including cooktops, ovens, and ranges, 

according to section 4, paragraph 4.2 of 

IEC Standard 62301 (First Edition). The 

IEC standard specifies a temperature 

range of 73.4 ± 9 °F. The current DOE 

test procedure for conventional cooking 

products includes a test room ambient 

air temperature specification of 77 ± 

9 °F. This varies slightly from the range 

specified by IEC Standard 62301 of 73.4 

± 9 °F. DOE believes that the higher 

temperatures allowed for active mode 

energy testing could be representative of 

ambient temperatures during a cooking 

process, but that it would be appropriate 

to maintain lower allowable 

temperatures for standby mode and off 

mode power consumption 

measurements as to be more 

representative of ambient conditions 

during those operating modes. The 

proposed test procedure would allow 

manufacturers of conventional cooking 

products to measure active mode 

performance and standby and off mode 

power simultaneously in the same room 

on multiple units, provided that the 

room ambient temperature falls within 

the range allowed by both ambient 

temperature requirements (i.e., any 

temperature between 68 and 82.4 °F). 

Alternatively, the proposed temperature 

specifications from IEC Standard 62301 

(First Edition) would allow a 

manufacturer to conduct standby mode 

and off mode testing separately from

11Each clock time was tested three times to 

confirm that the results were repeatable. The table 

shows the average power of the three tests.

of display segments energized in a seven-segment 

clock display for a given time. Different digit 

combinations associated with different times

elements. 

performance testing within an ambient 

temperature range of 73.4 ± 9 °F. DOE 

requests comment on the 

appropriateness of this proposed 

modified test room ambient temperature 

range. 

DOE also proposes additional 

clarifications to the power supply 

requirements for standby mode and off 

mode testing for conventional cooking 

products to require that the power 

supply frequency be 60 Hz ± 1 percent. 

The current DOE conventional cooking 

products test procedure requires that the 

power supply for the active mode test be 

240/120 V ± 2 percent or 208/120 ± 2 

percent (for basic models rated only at 

that rating), but the test procedure does 

not specify any power supply frequency 

requirements. As discussed earlier for 

dehumidifiers, section 4, paragraph 4.3 

of IEC Standard 62301 (First Edition) 

states that when the test voltage and 

frequency are not defined, the supply 

voltage and frequency shall be 115 V 

± 1 percent and 60 Hz ± 1 percent, 

respectively. Because the current DOE 

conventional cooking products test 

procedure does not specify a power 

supply frequency, DOE proposes that 

the 60 Hz ± 1 percent specified by IEC 

Standard 62301 (First Edition) be used 

for standby mode and off mode testing. 

DOE requests comments on its proposed 

amendments related to frequency. 

IEC Standard 62301 (First Edition) is 

written to provide some flexibility so 

that the test standard can be used to 

measure standby mode and off mode 

power for most household electrical 

appliances (including conventional 

cooking products). For that reason, it 

does not specify closely the test method 

for measuring the power consumption 

in cases in which the measured power 

is not stable. Section 5.3.2 of IEC 

Standard 62301 (First Edition) states 

that ‘‘[i]f the power varies over a cycle 

(i.e., a regular sequence of power states 

that occur over several minutes or 

hours), the period selected to average 

power or accumulate energy shall be 

one or more complete cycles in order to 

get a representative average value.’’ DOE 

investigated the possible regular 

sequences of power states for 

conventional cooking products in order 

to propose clarifying language to IEC 

Standard 62301 (First Edition) that 

would provide accurate and repeatable 

test measurements. 

DOE’s tests of standby power 

measurement in conventional cooking 

products indicate that a given unit or 

model with a clock display may use 

varying amounts of standby power 

depending on the clock time being 

displayed. DOE tested a small number 

(7) of conventional cooking products 

from its test sample to determine the 

amount of variation in power 

consumption that is possible due to 

variations in the clock time being 

displayed. More specifically, DOE tested 

the products with clock settings of 1:11 

and 12:08, which represent the 

minimum and maximum amount of 

numerical display segments.11 Table 

III.1 shows the test results for the 

products that showed significant 

variation in power consumption 

depending upon the clock’s time 

display. According to DOE tests of 

conventional cooking products 

equipped with a 12-hour clock display, 

standby power use at different times 

during a 12-hour cycle could vary by as 

much as 44 percent.

DOE believes that the lack of 

specificity in IEC Standard 62301 (First 

Edition) about the test period could 

produce test results obtained during one 

time period that are not comparable to 

those obtained using other time periods. 

Such results would not necessarily 

represent the standby power 

consumption of conventional cooking 

products during all hours associated 

with standby mode. In addition, 

different testing laboratories could take 

different approaches in selecting cycles 

for testing. To assess alternatives to the 

test cycle specified in IEC Standard 

62301 (First Edition), DOE investigated 

alternative time periods and averaging 

methods for calculating representative 

standby power use, using data that DOE 

collected from microwave oven clock 

displays during its analyses for energy 

conservation standards for those 

products. DOE believes that those 

displays have cyclic variation in power 

consumption as a function of displayed 

time comparable to those in 

conventional cooking products. 

For a typical microwave oven display 

with a 12-hour clock feature, DOE 

measured average standby power over 

the full 12-hour period. This 

measurement provides the most 

accurate and repeatable results. 

However, because a 12-hour test could 

substantially add to manufacturer test 

burden, DOE sought to identify other, 

more-abbreviated testing options, all the 

while keeping the 12-hour test in mind 

as an appropriate frame of reference in 

terms of generating representative 

results. DOE then evaluated a method 

using 18 different clock display times to 

produce an average standby power 

measurement representative of a 12- 

hour cycle. (This is referred to as the 

‘‘18-point method.’’) This method was 

discussed in appendix 5B of the 

technical support document (TSD) for 

the November 2007 ANOPR. When this 

method is used, the standby power 

consumption and line voltage are 

measured as the clock is cycled through 

all the possible digit combinations (in 

terms of active elements).12 A regression

rulemaking. 

analysis is then performed to quantify 

the effect of the number of lit elements 

(by digit) and voltage on power 

consumption. The results were 

integrated across the number of minutes 

that each active element combination 

was ‘‘on’’ through the course of the 12- 

hour test period. As noted in chapter 5 

of the November 2007 ANOPR TSD, this 

methodology produced results for 

average standby power consumption 

that were within 1 to 2 percent of the 

12-hour test results. 

DOE also investigated whether a 

single 10-minute measurement period 

with a starting clock time of 3:33 would 

be a reasonable proxy for the 12-hour 

standby power measurement in the 

event that power consumption is not 

stable. DOE’s analysis indicates that the 

proportion of time that each possible 

number of segments in a 7-segment LED 

display that are lit over the 10-minute 

time period from 3:33 to 3:42 is 

representative of the distribution of lit 

segments over a 12-hour period with an 

arbitrary starting time.13 This suggests 

that the 10-minute test period starting at 

3:33 would produce average standby 

power measurements comparable to 

average standby power measured over 

12 hours. Table III.2 shows the average 

standby power measured for 11 units in 

DOE’s microwave oven test sample 

using the 18-point and 10-minute 

methodologies as compared to the 

12-hour test.

* Standby power measurements are scaled to normalize the supply power to 120.0 volts. 

** For this test, the supply power was significantly different than 120.0 volts. Therefore, DOE believes the scaling of the measured standby 

power and, thus, the percentage differences from the 12-hour standby power measurements are not valid for this test unit. 

Within DOE’s limited test sample, the 

average standby power measured over 

the specified 10-minute test period 

agrees within ± 2 percent of the average 

standby power measured over 12 hours. 

Therefore, DOE tentatively concludes 

that a 10-minute measurement period 

with a starting time of 3:33 would 

provide a valid measure of standby 

energy use for conventional cooking 

products, with power consumption 

varying according to the time displayed 

on the clock. DOE requests comment on 

the validity and comparability of the 

various tests examined, as well as which 

test(s) DOE should adopt for measuring 

standby mode and off mode energy use. 

As a related matter, DOE is aware that 

certain clock displays enter a higherpower state when one manually sets the 

time, and then after a prescribed 

interval, the clock enters a lower-power 

state (e.g., by dimming the display) that 

is representative of the power levels that 

would be associated with the display 

running without consumer interaction. 

Therefore, DOE has tentatively 

concluded that it would be appropriate 

to provide a second stabilization period 

after the clock display is set prior to the 

start of the measurement period. DOE 

testing of combination microwave 

ovens, which have similar clock 

displays as conventional cooking 

products, suggest that a second 

stabilization period of 10 minutes 

would be sufficient to ensure that the 

clock display has reached its more 

representative power state after setting 

the time. This approach would require 

setting the clock time to 3:23 in order 

to start the measurement period at 3:33 

after the 10-minute second stabilization 

period. Therefore, DOE has tentatively 

decided to specify that, for conventional 

cooking products for which standby 

power consumption is not stable, the 

clock display shall be set at 3:23 at the 

conclusion of the stabilization period 

specified in section 5.3 of IEC Standard 

62301 (First Edition), after which a 

second 10-minute stabilization period 

shall be provided, and the subsequent 

test period shall be 10 minutes. 

Alternatively, DOE believes that 

appropriate stabilization may be 

achieved by requiring only the 

10-minute stabilization period after 

setting the clock time to 3:23. DOE seeks 

comment on whether this alternative 

method in which the clock time is set 

to 3:23 prior to a 10-minute stabilization 

period, followed by a 10-minute 

measurement period commencing at 

3:33 would be appropriate. 

DOE acknowledges, however, that 

both the 18-point and 10-minute 

approaches for accelerated standby 

testing do not exclude the possibility 

that a product could be programmed to 

alter its behavior during such a test in 

order to minimize measured standby 

power consumption. For example, a 

conventional cooking product could be 

programmed to dim or alter its display 

only during the display times associated 

with the 18 measurement points or 

between display times 3:33 and 3:42. 

In light of the above, DOE is 

proposing to provide manufacturers of 

conventional cooking products the 

option to conduct either the full 12-hour 

test, the 10-minute test, or both (with 

the expectation that any test records 

will make clear which type of test(s) 

was (were) performed). If a 

manufacturer elects to perform both 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
75304 Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 

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. For 

purposes of enforcement testing, DOE 

reserves the right to use either test or 

both tests. Given that the 10-minute test, 

like the 12-hour test, is intended to 

represent standby mode and off mode 

energy use and based upon the research 

data discussed above, DOE proposes to 

clarify that the test results conducted 

under the two different tests must be 

within ± 2 percent of each other; 

otherwise, DOE will use the 12-hour test 

to determine compliance. DOE requests 

comment on its proposed approach 

requiring results under the 12-hour test 

and the 10-minute test to be within ± 2 

percent of each other and welcomes 

data which would show that some other 

range is more appropriate. 

DOE notes that the conventional 

cooking products test procedure is 

designed to provide an energy efficiency 

measurement consistent with 

representative average consumer use of 

these products, even if the test 

conditions and/or procedures may not 

themselves all be representative of 

average consumer use (e.g., testing with 

a display of only 3:33 to 3:42). DOE’s 

proposal reflects the statutory 

requirement, and the Department’s 

longstanding view, that the overall 

objective of the test procedure is to 

measure the product’s energy 

consumption during a representative 

average use cycle or period of use. 42 

U.S.C. 6293(b)(3). Further, the test 

procedure requires specific conditions 

during testing that are designed to 

ensure repeatability while avoiding 

excessive testing burdens. Although 

certain test conditions specified in the 

test procedure may deviate from 

representative use, such deviations are 

carefully designed and circumscribed in 

order to attain an overall calculated 

measurement of the energy 

consumption during representative use. 

Thus, it is—and has always been— 

DOE’s view that products should not be 

designed such that the energy 

consumption drops during test 

condition settings in ways that would 

bias the overall measurement, thereby 

making it unrepresentative of average 

consumer use. If a manufacturer 

incorporates a power-saving mode as 

part of the appliance’s routine 

operation, DOE’s test procedure would 

produce a representative measure of 

average consumer use if the unit 

powered down during the 10-minute 

test period for the same percentage of 

time that such powering down would be 

expected to occur during a typical 12- 

hour period, and, thus, such operation 

would be permissible. Although DOE 

believes that its proposed 10-minute test 

would be adequate for standby mode 

and off mode testing purposes, if it 

becomes aware of product design 

strategies which render the 10-minute 

test results unrepresentative, DOE 

reserves the right to perform a full 12- 

hour test in the context of enforcement 

testing. It has been the Department’s 

long-held interpretation that the 

purpose of the test procedure is to 

measure representative use. Ultimately, 

if DOE identifies a broad pattern of 

behavior which has the effect of 

circumventing its test procedure 

provisions, the Department may 

consider reopening the conventional 

cooking products test procedure for 

further rulemaking. 

DOE proposes to clarify in the 

conventional cooking products test 

procedure codified in 10 CFR 

430.23(i)(17) that the energy test 

procedure is designed to provide a 

measurement consistent with 

representative average consumer use of 

the product, even if the test conditions 

and/or procedures may not themselves 

all be representative of average 

consumer use (e.g. specified display 

times). However, in a proposed rule on 

certification, compliance, and 

enforcement published in the Federal 

Register on September 16, 2010, DOE 

proposed that it would be a prohibited 

act to either fail to test a covered 

product in conformance with applicable 

test procedure requirements or to engage 

in ‘‘deliberate use of controls or features 

in a covered product or covered 

equipment to circumvent the 

requirements of a test procedure and 

produce test results that are 

unrepresentative of a product’s energy 

or water consumption if measured 

pursuant to DOE’s required test 

procedure.’’ 75 FR 56796, 56825 (Sept. 

16, 2010) (citing proposed amendments 

to 10 CFR 429.31(a)(2)). Examples of 

products exhibiting such behavior are 

those products that can exhibit 

operating parameters (e.g. display 

wattage) for any energy using 

component that are not predictably 

varying functions of operating 

conditions or control inputs—such as 

when a display is automatically 

dimmed when test conditions or test 

settings are reached. DOE believes that 

retention of the ability to conduct 

enforcement testing using the 12-hour 

test will deter product designs that 

would not be representative under the 

10-minute test of the DOE test 

procedure. 

DOE seeks comment on the proposed 

approach above to address products 

equipped with controls or other features 

that modify the operation of energyusing components during testing. DOE’s 

proposed approach does not identify 

specific product characteristics that 

could render results generated under the 

test procedure unrepresentative when 

testing certain products (e.g. 

modification of operation based on 

display time). Rather, it clarifies the 

need to address any features that could 

potentially yield measurements 

unrepresentative of the product’s energy 

consumption during a representative 

use cycle. 

As discussed in section III.B, the 

current DOE conventional cooking 

products test procedure provides testing 

methods and calculations to account for 

energy use of a continuously-operating 

clock. The current test procedure 

requires that any electrical clock that 

uses energy continuously be 

disconnected, except for those that are 

an integral part of the timing or 

temperature-controlling circuit of the 

product. In cases where the 

continuously-operating clock is an 

integral part of the timing or 

temperature-control circuit and cannot 

be disconnected during the test, the test 

procedure requires that such clock 

energy use be subtracted from the oven, 

cooktop, or range test energy 

consumption. The test procedure also 

provides methods for measuring the 

power consumption of a clock, which is 

then multiplied by 8,760 hours (total 

hours per year) to determine the annual 

clock energy consumption. The annual 

clock energy consumption is included 

in the calculation of total annual energy 

consumption and EF. 

DOE believes that the testing 

provisions for clock energy 

consumption currently in the cooking 

products test procedure are no longer 

necessary because DOE proposes to 

amend the conventional cooking 

products test procedure to fully account 

for standby mode and off mode energy 

consumption, which include clock 

energy consumption. DOE proposes to 

incorporate standby mode and off mode 

energy consumption into the total 

annual energy consumption and EF 

calculations. Therefore, DOE proposes 

to remove the provisions for clock 

energy consumption from the 

conventional cooking products test 

procedure and to replace them with the 

provisions for measuring all standby 

mode and off mode energy 

consumption. (See section III.E.)

16 DOE used a value of 8760 total hours per year 

in all of its analyses in today’s notice, based on 24 

hours/day × 365 days/year. The current dishwasher 

test procedure includes a value of 8766 hours, 

which results from 24 hours/day × 365.25 days/ 

year. Although the latter equation is more accurate, 

DOE has retained the value of 8760 in all its 

proposed test procedure amendments in today’s 

notice, and notes that the two values vary by a 

negligible 0.07 percent.

Measurements,’’ included as entry No. 3 in the 

docket for this rulemaking. 

dishwashers, dehumidifiers, and 

conventional cooking products are 

expressed in watts (W). The annual 

energy consumption in each of these 

modes is the product of the power 

consumption and the time spent in that 

particular mode per year. The following 

sections describe how the annual energy 

use associated with each operating 

mode is calculated for the products that 

are the subject of this rulemaking. 

1. Dishwashers 

Energy use for dishwashers is 

expressed in terms of average annual 

energy use and total energy used per 

dishwasher cycle. (10 CFR 430.23(c)) As 

discussed in section III.F, DOE has 

tentatively determined that it is 

technically feasible to incorporate 

measures of standby mode and off mode 

energy use into the overall energy use 

metric (i.e., average annual energy use) 

as required by the EISA 2007 

amendments to EPCA. (42 U.S.C. 

6295(gg)(2)(A)) Therefore, DOE has 

examined standby mode and off mode 

energy consumption in terms of annual 

energy use, expressed in kWh per year. 

In the current DOE dishwasher test 

procedure, the annual standby mode 

energy consumption is calculated by 

multiplying the average standby power 

use by the number of standby hours per 

year. The number of standby hours per 

year is equal to the number of total 

hours per year minus the product of the 

representative average dishwasher use 

of 215 cycles per year times the average 

wash cycle time. The average wash 

cycle time is derived from test 

measurements of the duration of the 

various cycles available on a 

dishwasher, such as normal, truncated 

normal, and sensor cycles. The average 

standby energy consumption is then 

added to the annual machine energy use 

(which includes any water heating 

within the dishwasher) and annual 

water energy use (energy used by the 

residence’s water heater to heat the 

water prior to being supplied to the 

dishwasher during the cycle) to 

calculate the EAEU. DOE is proposing 

in today’s NOPR that the active mode 

hours be determined using the approach 

specified in the current DOE dishwasher 

test procedure. That procedure uses test 

measurements of the duration of the 

various cycles available on a dishwasher 

to determine its average wash cycle time 

and then multiplies that average wash 

cycle time by 215 cycles per year. DOE 

proposes that the remaining non-active 

hours be distributed between the 

appropriate standby and off modes. DOE 

investigated the annual hours and 

energy consumption associated with 

each possible dishwasher operating 

mode, including inactive, delay start, 

cycle finished, off, and active modes, in 

order to propose methods for calculating 

the total annual energy use. 

As part of the November 2007 

ANOPR, DOE estimated the length of a 

dishwasher cycle to be one hour. 72 FR 

64432, 64471 (Nov. 15, 2007). The DOE 

test procedure assumes 215 dishwasher 

cycles per year. (10 CFR part 430 

subpart B, appendix C, section 5.6) 

Therefore, DOE estimates that 215 hours 

per year are dedicated to active mode. 

Data regarding the amount of time 

dishwashers spend in the remaining 

non-active modes is very limited. A 

study conducted in Australia, ‘‘2005 

Intrusive Residential Standby Survey 

Report,’’ surveyed 120 households and 

provided information regarding delay 

start for dishwashers. The report stated 

that about 25 percent of dishwashers 

were found to have delay start 

capabilities. Twenty percent of those 

surveyed who had dishwashers with 

delay start capabilities indicated they 

used this function. The study also 

reported an average power consumption 

for delay start mode of 3.8 W.14 DOE 

notes the study reported data on 

dishwashers installed in the households 

at the time of the survey. Thus, the data 

may not be representative of 

dishwashers currently on the market. 

Because this study provided only 

limited information on consumer usage 

patterns for a limited number of modes, 

DOE investigated other sources of 

consumer usage data for dishwashers 

regarding the amount of time 

dishwashers spend in each possible 

non-active mode. 

One IEC report 15 surveyed 

dishwasher usage patterns in Germany, 

Italy, and the United Kingdom 

households. Dishwashers in these 

households averaged 213 cycles per 

year, which is close to the value 

specified by the current DOE 

dishwasher test procedure of 215 cycles 

per year. DOE believes the results of this 

survey are consistent with consumer 

behavior in the United States. DOE 

notes that the sample size of this survey 

was only 79 households. Regarding 

delay start, called ‘‘time delay function’’ 

in the survey, data showed 44 percent 

of dishwashers had a delay start 

function. Thirty-four percent of the 

respondents who owned a dishwasher 

with a delay start function used the 

function. Respondents who did use 

delay start used it for 16 percent of all 

cycles, with an average delay setting of 

5.1 hours. If the results for delay start 

are applied to all dishwashers and 

cycles, the average delay start per cycle 

is just under 8 minutes, or 26 hours per 

year. For cycle finished mode, called 

‘‘program end’’ in the survey, data from 

all households showed the average time 

after program end and before switching 

the machine off was 1.1 hours. If results 

for cycle finished mode are applied to 

all dishwashers and cycles, the average 

total cycle finished mode hours is 237 

hours per year. 

DOE is using data from this IEC 

survey in its estimates of the energy 

consumption associated with the 

different dishwasher modes. Of a total 

8,760 hours per year,16 the hours not 

associated with active, delay start, or 

cycle finished mode are allocated to off 

and inactive modes. To determine the 

approximate wattages associated with 

standby modes and off mode, DOE 

conducted internal testing on 14 

dishwashers.17 Average power levels in 

watts are multiplied by the estimated 

number of hours allocated per year to 

each mode to calculate the annual 

energy use for each mode. For example, 

the active mode power and annual 

energy use were calculated based on 215 

cycles per year for a standard-size 

dishwasher with a minimum standard 

EF of 0.65. The typical average per-cycle 

energy use for such a dishwasher is 

calculated to be 1.54 kWh per cycle. The 

product of these inputs yields annual 

energy use in active mode of 331.1 kWh 

per year. In summary, Table III.3 

presents the comparison of the average 

wattages and annual energy use 

associated with all dishwasher modes.

* Based on IEC 59A/122/INF. 

** (8,760 hours per year—215 active mode hours—26 delay start hours—237 cycle finished hours) = 8,282 hours. 

As discussed in section III.C, DOE 

believes that delay start would not be 

considered part of standby mode, but 

instead, it would be an active mode. For 

the reasons discussed earlier, DOE is not 

proposing amendments to the 

dishwasher test procedure to define 

‘‘delay start mode’’ or to measure power 

consumption in this mode. The 

comparison of annual energy 

consumption of different dishwasher 

modes presented in Table III.3 shows 

that energy use associated with delay 

start mode is relatively insignificant 

because of the small number of annual 

hours associated with this mode. In 

addition, the power levels in this mode 

are similar to those for off/inactive 

modes for dishwashers currently on the 

market. Therefore, DOE proposes to 

allocate delay start mode hours (which 

total 26 for this example case) to the 

inactive and off modes (which would 

then total 8,308 for this example case). 

DOE also proposes that 237 hours be 

associated with cycle finished mode for 

dishwashers capable of functioning in 

such a mode, as presented in Table III.3. 

To determine the annual hours per 

mode for dishwashers for which not all 

standby modes are possible, DOE 

proposes to reallocate the hours for 

modes that are not part of the 

dishwasher’s design. For example, if 

cycle finished mode is not part of a 

dishwasher’s design, the off/inactive 

mode hours would be the total hours 

per year minus the active mode hours 

per year. If cycle finished mode is part 

of the design, the off/inactive mode 

hours would be the total hours per year 

minus the active mode hours per year 

minus the 237 cycle finished mode 

hours. 

DOE believes that the proposed 

definition of ‘‘off mode’’ as applied to 

dishwashers refers to units with 

mechanical rather than electronic 

controls, or units with electronic 

controls combined with a mechanical 

switch, with which the user can deenergize the electronic controls. 

Reactivation of the dishwasher with a 

push-button sensor, touch sensor, or 

other similar device that consumes 

power is considered to be a standby 

mode feature under the proposed 

definition. The proposed definition 

states that standby mode facilitates the 

activation of other modes (including 

activation or deactivation of active 

mode) by remote switch (including 

remote control), internal sensor, or 

timer. DOE believes there are few 

dishwashers with electronic controls 

that have an additional mechanical on/ 

off switch. Therefore, the combined 

inactive/off mode hours would most 

likely be allocated fully either to 

inactive or off mode, depending on the 

type of controls present on the 

dishwasher. DOE does not have market 

share information to determine how 

many dishwashers are currently 

shipped with electromechanical 

controls or the proportion of time spent 

in off mode for units equipped with a 

mechanical on/off switch. For 

dishwashers with electronic controls 

plus a mechanical on/off switch, DOE is 

proposing to allocate half of the nonactive hours to inactive and half to off 

modes. DOE welcomes comment and 

additional information on this point, 

and on the proposed approach for 

calculating energy use for standby mode 

and off mode. 

In conclusion, DOE proposes to 

determine dishwasher standby mode 

and off mode energy use by: 

(1) Calculating the product of wattage 

and allocated hours for all possible 

standby and off modes; (2) summing the 

results; and (3) dividing the sum by 

1,000 to convert from watt-hours (Wh) 

to kWh. DOE invites comments on this 

proposed methodology and associated 

factors, including accuracy, allocation of 

annual hours, and test burden for 

manufacturers. DOE may also consider 

adoption in the final rule of the 

following alternative methodology 

based on comments received. 

The comparison of annual energy use 

of different dishwasher product modes 

shows that cycle finished mode 

represents a relatively small number of 

hours per year at a low power 

consumption level. For dishwashers 

currently on the market, these levels are 

distinct from but comparable to those 

for off/inactive modes. Thus, DOE could 

adopt a test procedure for dishwashers 

that would specify that only hours spent 

in off and inactive modes would be 

considered when calculating energy use 

associated with standby mode and off 

mode. In that case, all of the non-active 

hours would be allocated to the inactive 

and off modes. DOE invites comment on 

whether such an alternative would be 

representative of the standby mode and 

off mode power consumption of 

dishwashers currently on the market. 

2. Dehumidifiers 

Energy use for dehumidifiers is 

expressed as EF, which is the ratio of 

liters of water removed from the air per 

kWh. As discussed in section III.F, DOE 

has determined it is technically feasible 

to incorporate measures of standby 

mode and off mode energy use into the 

overall energy use metric, and 

accordingly, DOE is making a proposal 

consistent with that determination, as 

required by the EISA 2007 amendments 

to EPCA. (42 U.S.C. 6295(gg)(2)(A)) 

Thus, DOE proposes that a 

dehumidifier’s total annual energy use 

be estimated by combining standby 

mode and off mode energy consumption 

with active mode consumption based on 

the number of hours a dehumidifier 

spends in each mode. 

In order to establish the number of 

hours per year a dehumidifier spends in 

different operating modes, DOE 

investigated studies of dehumidifier 

usage patterns. Table III.4 shows 

estimates of monthly dehumidifier 

usage obtained from a variety of sources, 

including a 1998 Arthur D. Little (ADL) 

report,18 a 2005 Lawrence Berkeley 

National Laboratory (LBNL) report,19

consultation with manufacturers and 

others familiar with the product. Most 

of these estimates demonstrate heavy 

dehumidifier usage during the summer 

months and none between the months 

of November and March. DOE proposes 

to use AHAM’s mid-level estimate of 

active mode hours for the purpose of 

this analysis. The AHAM data were 

developed based on manufacturer 

experience. DOE believes, therefore, that 

the data represent a reasonable 

assessment of the average usage patterns 

for dehumidifiers. As shown in Table 

III.4, AHAM’s mid-level estimate of 

annual hourly operation is 1,095 active 

mode hours, while other estimates range 

from 875 to 4,320 active mode hours. 

For the purposes of this analysis, DOE 

proposes that 1,095 hours be associated 

with active mode.

DOE is aware that a dehumidifier may 

be unplugged for a certain percentage of 

time, and, therefore, will not be in either 

standby mode or off mode. DOE does 

not have data regarding the amount of 

time a typical dehumidifier is 

unplugged. However, in its comment on 

the framework document for the 

residential dishwasher, dehumidifier, 

cooking products, and commercial 

clothes washer energy conservation 

standards rulemaking, AHAM stated 

that dehumidifiers are normally used on 

a regional basis in basements during 

humid summer hours in northern 

climates. Reviewing the survey data 

presented in Table III.4, which show no 

active mode hours of operation for the 

months from November to March and 

minimal active mode hours in April, in 

the context of AHAM’s comment has led 

DOE to tentatively conclude that 

dehumidifiers would likely be 

unplugged during the period from 

November to March and for half of April 

(5.5 months). Therefore, DOE estimates 

the time dehumidifiers spend 

unplugged as 3,984 hours. 

Next, DOE investigated how the 

remaining 3,681 non-active hours 

(8,760¥1,095—3,984) would be 

allocated to the other operating modes. 

DOE is not aware of any reliable 

consumer usage data on the number of 

hours per year dehumidifiers spend in 

delay start and bucket full/removed 

modes. In the absence of such data, DOE 

estimated the time spent in these modes 

in the manner described below. 

To estimate a representative number 

of annual hours for bucket full/removed 

mode, DOE estimated the number of 

times a dehumidifier bucket would be 

expected to fill with water and the 

number of hours the bucket would be 

expected to remain full before being 

emptied. As discussed in the November 

2007 ANOPR, DOE estimated that the 

predominant dehumidifier product 

class, which has 25.01–35 pints per day 

capacity and operates at the existing 

energy conservation standard level (EF 

of 1.35 liters per kWh), would have an 

annual energy use of about 480 kWh per 

year. 72 FR 64432, 64473 (Nov. 15, 

2007). DOE estimates that such a 

dehumidifier would remove 648 liters of 

water from the air per year (480 kWh 

per year × 1.35 liters per kWh = 648 

liters per year). Based on the units in 

DOE’s test sample with a capacity 

between 25.01–35 pints per day, DOE 

estimates that the average condensate 

collection bucket size for this product 

class would be 18.7 pints, or 8.9 liters.22

If it is assumed the typical consumer 

will run a dehumidifier until the bucket 

is full before emptying it, DOE estimates 

that dehumidifiers will reach bucket 

full/removed mode 73 times per year 

(648 liters of water removed from the air 

per year/8.9 liter bucket capacity = 73). 

Thus, the 1095 active mode hours 

divided by 73 bucket full mode events 

results in an estimate of 15 hours that 

the dehumidifier spends in active mode 

per bucket fill. DOE believes that 

consumers will not empty the collection 

bucket more than once per day, so the 

dehumidifier is likely to remain full an 

average of 9 hours per bucket-full event 

(24 hours per day ¥ 15 hours per 

bucket fill = 9 hours). Based on these 

assumptions, DOE estimates the number 

of bucket full/removed annual hours to 

be 657 hours (73 bucket fills per year × 

9 hours bucket remains full before being 

emptied and replaced). 

To determine the number of annual 

hours associated with delay start mode, 

DOE surveyed dehumidifier models 

available on the market. DOE 

determined that about 19 percent of 

dehumidifiers have a delay start mode 

function and that the delay start 

function can be set for up to 24 hours. 

DOE estimates that the delay start 

function will only be used on 50 percent 

of these 19 percent of dehumidifiers that 

have the function. DOE also estimates 

that consumers that do use the delay 

start function will use it once a day for 

10 percent of the 199 dehumidifying 

days per year. (The dehumidifying days 

are the 6.5 months of the year during 

which the dehumidifier may be 

operated in active mode, as shown in 

the AHAM’s mid-level estimate in Table 

III.4.) DOE also estimates that 

consumers will use an average delay 

setting of 12 hours (which is half of the 

maximum delay start time available on 

dehumidifiers.) Based on these 

assumptions, DOE estimates that the 

average time a dehumidifier is operating 

in delay start mode per active mode day 

is 6.8 minutes, or 23 hours per year. 

The estimates of annual hours and 

energy consumption associated with the 

active, delay start, and bucket full/ 

removed modes are displayed in Table 

III.5. To determine the approximate 

wattages associated with standby modes 

and off mode, DOE conducted internal 

testing on 13 dehumidifiers.23 Average 

power levels in watts are multiplied by

the estimated number of hours allocated 

per year to each mode to calculate the 

annual energy use for each mode. For 

the purpose of this analysis, DOE 

estimated that the remaining 3,001 

annual hours (3,681 non-active mode 

hours ¥ 23 delay start mode hours ¥ 

657 bucket/full removed mode hours = 

3,001 hours) would be split between offcycle mode, inactive mode, and off 

mode. The split between these three 

modes is discussed later in this section.

per day) × 12 hours (average programmed duration of delay start period) × 199 days (number of dehumidifying days per year) = 23 hours. 

** 73 (bucket fills per year) × 9 hours (hours the bucket remains full before being emptied and replaced) = 657 hours. 

As discussed in section III.C, DOE 

believes that delay start mode would not 

be considered part of standby mode, but 

instead would be a form of active mode. 

Therefore, DOE is not proposing 

amendments to the dehumidifier test 

procedure to define ‘‘delay start mode’’ 

or to measure power consumption in 

this mode. The comparison of the 

annual energy consumption of different 

dehumidifier modes presented in Table 

III.5 shows that energy use associated 

with delay start mode is relatively 

insignificant because dehumidifiers 

spend only a small number of hours in 

this mode. In addition, the power levels 

in delay start mode are similar to those 

for off/inactive modes for dehumidifiers 

currently on the market. Therefore, DOE 

proposes to allocate delay start mode 

hours (which total 23 hours for this 

example case) to the off-cycle, inactive, 

and off modes (which would then total 

3,024 hours in this example case). 

To determine the annual hours per 

mode for dehumidifiers for which not 

all standby modes are possible, DOE 

estimated values by reallocating the 

hours associated with various standby 

modes that are not present using the 

ratios discussed previously. DOE’s logic 

for this distribution of hours follows. 

For example, if bucket full/removed 

mode is not possible for dehumidifiers 

with a continuous drain and no 

condensate collection bucket, off-cycle/ 

inactive/off modes would equal 3,024 

off-cycle/inactive/off mode hours + 657 

bucket full/removed hours = 3,681 

hours. DOE believes the proposed 

definition of ‘‘off mode’’ as applied to 

dehumidifiers is similar to that for 

dishwashers. Off mode, as applied to 

dehumidifiers, refers to units with 

mechanical rather than electronic 

controls, or units with electronic 

controls combined with a mechanical 

switch that the user can use to deenergize the electronic controls. DOE 

observed during testing that 

dehumidifiers with electronic controls 

require that a humidity level be set 

when the unit is powered on; if the 

room humidity level is above the level 

set, the unit begins operating in active 

mode. Therefore, DOE believes that 

when a dehumidifier with electronic 

controls is powered on, the majority of 

the non-active mode hours (i.e., when 

the relative humidity level in the room 

is below the dehumidifier humidity set 

point) would be associated with offcycle mode. If a dehumidifier is 

equipped with electronic controls and a 

push-button sensor to power on the 

controls, it operates in the inactive 

mode when the unit is not powered on. 

DOE believes that a dehumidifier with 

a remote control can be controlled 

whenever it is plugged in. Thus, these 

units do not have an off mode and 

instead operate in the inactive mode 

when the unit is not powered on, and 

operate in off-cycle or active mode 

when the unit is powered on. However, 

if a dehumidifier allows the user to 

switch off remote control operation, it 

would be capable of off, inactive, and 

off-cycle modes. DOE does not have 

consumer usage data on the distribution 

of annual mode hours for dehumidifiers 

among the different combinations of offcycle, inactive, and off modes. DOE 

proposes that the annual hours be split 

evenly between the off-cycle, inactive, 

and off modes depending on which 

modes are present on the dehumidifier 

under test. Otherwise, for units which 

are capable of operating in only offcycle, inactive, or off mode, DOE 

proposes that all of the hours be 

allocated to the appropriate mode. DOE 

welcomes any data available on this 

issue. 

In summary, DOE proposes to amend 

the dehumidifier test procedure to 

determine energy use associated with 

standby mode and off mode by: 

(1) Calculating the products of wattage 

and allocated hours for all possible 

standby and off modes; (2) summing the 

results; and (3) dividing the sum by 

1,000 to convert from Wh to kWh. DOE 

invites comments on this proposed 

methodology for dehumidifiers and 

associated factors, including accuracy, 

allocation of annual hours, and test 

burden. DOE may also consider 

adoption in the final rule of the 

following alternative methodology 

based on comments received. 

The comparison of annual energy use 

of different dehumidifier modes shows 

that, for dehumidifiers currently on the 

market, power consumption levels in 

bucket full/removed mode are distinct 

from but comparable to those for offcycle/inactive/off modes. Thus, DOE 

could adopt an approach for 

dehumidifiers limited to specifying the 

hours for only off-cycle, inactive, and 

off modes when calculating energy use 

associated with standby mode and off 

mode. In that case, all of the non-active 

hours (3,681 hours total), including 

bucket full/removed mode, would be 

allocated to the off-cycle, inactive, and 

off modes. DOE invites comment on 

whether this alternative would be 

representative of the standby mode and 

off mode power consumption of 

dehumidifiers currently on the market. 

3. Conventional Cooking Products 

Energy use for conventional cooking 

products is expressed as EF, which is 

the ratio of annual cooking energy 

output to the annual energy input. As 

discussed in section III.F, DOE has 

determined it is technically feasible to 

incorporate measures of standby mode 

and off mode energy use into the overall 

energy use metric, and accordingly, 

DOE is making a proposal consistent 

with that determination, as required by 

the EISA 2007 amendments to EPCA.

incorporate standby mode and off mode 

power consumption into the overall 

energy consumption for conventional

cooking products, DOE analyzed data on 

the usage patterns and power 

consumption in these modes on an 

annual basis for each product class of 

conventional cooking products, as 

discussed below. 

a. Conventional Ovens 

DOE investigated the hours and 

energy consumption associated with 

each possible operating mode for 

conventional ovens, including inactive, 

Sabbath, delay start, cycle finished, off, 

and active modes. 

DOE is unaware of reliable consumer 

usage data for the number of hours 

spent in active mode for conventional 

ovens. To estimate the number of 

annual active mode hours, DOE 

reviewed data from the Energy 

Information Administration (EIA)’s 2005 

‘‘Residential Energy Consumption 

Survey’’ (RECS).24 RECS is a national 

sample survey of housing units that 

collects statistical information on the 

consumption of and expenditures for 

energy in housing units, along with data 

on energy-related characteristics of the 

housing units and occupants. RECS 

provides survey data on the frequency 

of conventional oven use per week. 

Based on its analysis of RECS data, DOE 

estimates that the number of active 

mode cooking cycles per year is 211. 

Assuming that a conventional oven 

active mode cycle is on average 1 hour 

long, DOE estimates that the number of 

active mode hours per year for a 

conventional oven is 211. DOE 

welcomes information and data on such 

average cycle times, as well as the 

number of annual conventional oven 

usage cycles. For the purposes of this 

analysis, DOE proposes that 211 hours 

be associated with active mode and the 

remaining 8,549 hours of the year be 

associated with the remaining possible 

modes, including inactive, delay start, 

cycle finished, Sabbath, and off mode. 

RECS also provides consumer usage 

data on how many conventional ovens 

are used per household. Based on its 

analysis of RECS data, DOE estimates 

that 1.04 conventional ovens are used 

per household. 

Similarly, DOE is not aware of reliable 

consumer usage data for the number of 

hours conventional ovens spend in 

various non-active modes. DOE 

estimated the time associated with 

Sabbath mode in conventional ovens 

based on the percentage of Jewish 

households in the United States that 

observe kosher practices at home (the 

households most likely to use Sabbath 

mode), the number of annual work-free 

days, and the number of conventional 

ovens used per household. DOE believes 

this represents the population of 

consumers which uses Sabbath mode 

features in a conventional oven. DOE 

estimates the percentage of Jewish 

consumers observing kosher practices at 

home to be about 0.54 percent of the 

total U.S. population, based on data 

from a 2000–01 population survey by 

the United Jewish Communities,25

which reported that 21 percent of 2.9 

million Jewish households (which 

equals 609,000 households) in the 

United States keep a kosher home, 

compared to 112,386,298 total 

households in the United States as of 

2008.26 DOE also estimates 1,584 hours 

of annual work-free hours, which would 

comprise the weekly Sabbath and the 

annual non-working Jewish holidays.27

Using these estimates as well as the 

number of ovens per household as 

determined earlier in this section, DOE 

estimates that 8.9 hours per year would 

be associated with Sabbath mode for 

conventional ovens. The calculation is: 

0.54 percent (percent of U.S. households 

that observe kosher practices) × 1,584 

hours (annual work-free hours per year) 

× 1.04 (conventional ovens per 

household) = 8.9 hours per year. 

DOE also estimated the annual hours 

associated with delay start mode. DOE 

analyzed data from a DOE survey of 

ovens currently available on the market 

and estimated that 96 percent of 

conventional ovens are equipped with a 

delay start function. DOE notes that 

conventional ovens may offer a delay 

start function of up to 24 hours. 

However, DOE is unaware of any 

reliable usage data for the delay start 

function. In the absence of data, DOE 

has estimated that, given the prevalence 

of delay start-equipped ovens, 

approximately 50 percent of consumers 

will use this feature for at least some 

cooking cycles. DOE further estimates 

that consumers that use the delay start 

function will use it for 5 percent of 

cooking cycles and will program a 12- 

hour delay start period. (The 12-hour 

delay is half of the maximum delay start 

time available on conventional ovens, 

which is also approximately the time 

between preparation in the morning and 

initiating a cooking cycle in the 

evening.) Applying these estimates to all 

conventional ovens and cooking cycles 

(211 cycles per year as determined 

earlier), DOE estimates that the average 

time a conventional oven is operating in 

delay start mode per cycle is 17 

minutes, or 61 hours per year. 

To estimate the annual time 

associated with cycle finished mode, 

DOE assumed that conventional ovens 

on average remain in cycle finished 

mode for 5 minutes after every cycle. 

Calculations based on that assumptions 

result in an estimate of 18 annual hours 

associated with cycle finished mode. 

The remaining 8,461.1 annual hours 

not associated with active, Sabbath, 

delay start, or cycle finished mode are 

allocated to off and inactive modes 

(8,760 annual hours ¥ 211 active mode 

hours ¥ 8.9 Sabbath mode hours ¥ 61 

delay start mode hours ¥ 18 cycle 

finished mode hours). The hours for the 

relevant modes and estimates of power 

input and energy use for conventional 

ovens are summarized in Table III.6. 

The approximate wattages associated 

with each mode, other than active 

mode, were determined from internal 

testing conducted by DOE on 12 

conventional ovens.28 For active mode, 

the typical average power level is 

calculated by dividing the annual 

energy consumption of a baseline 

efficiency model electric self-cleaning 

oven (EF of 0.1099 and annual energy 

consumption of 171.0 kWh per year) by 

211 active hours, which equals 810 W. 

Electric self-cleaning ovens were 

determined to be the predominant 

conventional electric oven product class 

as part of the November 2007 ANOPR. 

72 FR 64432, 64474 (Nov. 15, 2007). 

Although the hours per mode presented 

in Table III.6 are estimates based on 

limited study data, DOE believes the 

energy patterns illustrated in this table 

are representative for most conventional 

ovens.

12 hours (average programmed duration of delay start period) × 211 (annual cooking cycles) = 61 hours. † 211 (annual cycles) × 5 minutes (estimated cycle finished minutes per cycle) = 18 hours. 

As discussed in section III.C, DOE 

believes delay start mode would not be 

considered part of standby mode, but 

instead, it would be a form of active 

mode. Therefore, DOE is not proposing 

amendments to the conventional oven 

test procedure to define delay start 

mode or to measure power consumption 

in this mode. The comparison of annual 

energy consumption of different 

conventional oven modes shows that 

energy use associated with delay start 

mode is relatively insignificant because 

only a small number of hours are 

associated with this mode. In addition, 

the power levels in this mode are 

similar to those for off/inactive modes 

for conventional ovens currently on the 

market. For this reason, DOE proposes 

to allocate delay start mode hours 

(which total 61 hours for this example 

case) to the inactive and off modes 

(which would then total 8,522.1 hours 

in this example case.) 

As also discussed in section III.C, 

DOE believes that Sabbath mode would 

be considered part of the active mode. 

Therefore, DOE is not proposing 

amendments to the conventional 

cooking products test procedure to 

define ‘‘Sabbath mode’’ or to measure 

power consumption in this mode. 

However, the comparison of annual 

energy consumption shows that energy 

use associated with Sabbath mode is 

insignificant because only a small 

number of hours are associated with this 

mode. DOE proposes to allocate the 

Sabbath mode hours (which total 8.9 

hours for this example case) to the 

active mode (which would then total 

219.9 hours in this example case.) 

To determine the annual hours per 

mode for conventional ovens for which 

not all standby modes are possible, DOE 

estimated values based upon 

reallocating the hours for modes that are 

not present using the ratios discussed 

previously. If cycle finished mode, 

which is assumed to be a fixed value of 

18 hours per year, is not present, the off/ 

inactive mode hours would be 8,760 

total hours ¥ 219.9 active mode hours 

= 8,540.1 hours. If cycle finished mode 

is possible, the off/inactive mode hours 

would be 8,760 total hours ¥ 219.9 

active mode hours ¥ 18 cycle finished 

hours = 8,522.1 hours. 

DOE believes the proposed definition 

of ‘‘off mode’’ as applied to conventional 

ovens refers to units with mechanical 

rather than electronic controls, or units 

with electronic controls combined with 

a mechanical switch, with which the 

user can de-energize the electronic 

controls. Reactivating a conventional 

oven with a push-button sensor, touch 

sensor, or other similar device that 

consumes power is considered to be a 

standby mode feature under the 

proposed definitions. DOE believes 

there are few conventional ovens with 

electronic controls that have an 

additional mechanical off switch. 

Therefore, the combined inactive/off 

mode hours would most likely be 

allocated fully either to inactive or off 

mode, depending on the type of controls 

present on the conventional oven. DOE 

does not have market share information 

to determine how many conventional 

ovens are currently shipped with 

electromechanical controls. For 

conventional ovens with electronic 

controls plus a mechanical off switch, 

DOE proposes to allocate half of the 

non-active hours to inactive and half to 

off modes. DOE welcomes comment and 

additional information on this point, 

and on the proposed approach for 

calculating energy use for standby mode 

and off mode, including the decision to 

allocate all non-active mode hours to off 

and inactive modes. 

In summary, DOE proposes to 

determine conventional oven energy use 

associated with standby mode and off 

mode by: (1) Calculating the product of 

wattage and allocated hours for all 

possible standby and off modes; (2) 

summing the results; and (3) dividing 

the sum by 1,000 to convert from Wh to 

kWh. DOE invites comments on this 

proposed methodology and associated 

factors, including accuracy, allocation of 

annual hours, and test burden. DOE may 

also consider adoption in the final rule 

of the following alternative 

methodology based on comments 

received. 

The comparison of annual energy use 

of different conventional oven product 

modes shows that cycle finished mode 

represents a relatively small number of 

hours at a low power consumption 

level. For conventional ovens currently 

on the market, these levels are distinct 

from but comparable to those for off/ 

inactive mode. Thus, DOE could adopt 

an approach that would be limited to 

specifying the hours for only off/ 

inactive mode when calculating energy 

use associated with standby and 

inactive/off modes. In that case, all of 

the non-active hours (8,540.1 hours 

total) would be allocated to the inactive/ 

off mode. DOE invites comment on 

whether such an alternative would be 

representative of the standby mode and 

off mode power consumption of 

conventional ovens currently on the 

market. 

b. Conventional Cooktops 

DOE investigated the hours and 

energy consumption associated with 

each possible operating mode for 

conventional cooktops, including 

inactive, Sabbath, off, and active modes. 

DOE did not observe any models 

capable of delay start mode or cycle 

finished mode, and, therefore DOE did 

not consider these modes for the 

purpose of this analysis. 

DOE notes that RECS only provides 

usage data for conventional ovens and 

does not provide usage data for 

conventional cooktops. As discussed 

earlier, DOE estimated based on the 

2005 RECS that there are 211 active 

mode cooking cycles per year for 

conventional ovens, resulting in 211 

active mode hours per year, and that the

docket for this rulemaking. 

balance of the year (8,549 hours) is the 

established number of hours associated 

with Sabbath, cycle finished, and off/ 

inactive modes. DOE believes that 

conventional cooktops would have 

similar active mode usage patterns as 

conventional ovens. Therefore, DOE is 

proposing to use the same 211 active 

mode cycles per year and annual active 

mode hours for conventional cooktops, 

so the remaining 8,549 hours of the year 

would be associated with standby mode 

and off mode. DOE welcomes 

information and data on such average 

cycle times, as well as annual 

conventional cooktop usage. DOE also 

notes that RECS does not provide usage 

data on how many conventional 

cooktops are used per household. As a 

result, DOE is proposing to estimate that 

the average household uses one 

conventional cooktop. 

DOE is not aware of reliable consumer 

usage data for hours spent in different 

standby and off modes in conventional 

cooktops. As was done for conventional 

ovens, DOE estimated the time 

associated with Sabbath mode in 

conventional cooktops based on the 

percentage of Jewish households in the 

United States that observe kosher 

practices at home (the households most 

likely to use Sabbath mode), the number 

of annual work-free days, and the 

number of conventional cooktops used 

per household. As it did for 

conventional ovens, DOE estimates that 

about 0.54 percent of U.S. households 

keep kosher homes and that there are 

approximately 1,584 annual work-free 

hours (i.e., the weekly Sabbath and the 

annual Jewish holidays). Applying these 

estimates to the number of cooktops per 

household as estimated earlier in this 

section, and estimating that, based on 

the relatively few cooktop models 

certified as Sabbath-compliant 29 and 

the greater availability of ovens with a 

dedicated Sabbath mode that DOE 

estimates would be used in place of 

cooktops on the Sabbath at least 75 

percent of the time, DOE estimates that 

2.1 hours per year would be associated 

with Sabbath mode for conventional 

cooktops. The calculation is as follows: 

0.54 percent (percent of U.S. households 

that observe kosher practices) × 1,584 

hours (annual work-free hours per year) 

× 1 (conventional cooktops per 

household) × 25 percent (percent of 

times that cooktops would be used on 

the Sabbath in place of or in addition to 

using an oven) = 2.1 hours per year. 

The remaining 8,546.9 annual hours 

not associated with active or Sabbath 

mode are allocated to off and inactive 

modes (8,760 annual hours ¥ 211 active 

mode hours ¥ 2.1 Sabbath mode hours). 

The hours for the relevant modes and 

estimates of power input and energy are 

summarized in Table III.7. The 

approximate wattage associated with 

off/inactive mode was determined from 

internal testing conducted by DOE on 

eight conventional cooktops.30 For 

active mode, the typical average power 

level is calculated by dividing the 

annual energy consumption of a 

baseline efficiency model electric 

smooth cooktop (EF of 0.742 and annual 

energy consumption of 128.2 kWh per 

year) by 211 active hours which equals 

608 W. Electric smooth cooktops were 

determined to be the predominant 

conventional electric cooktop product 

class as part of the November 2007 

ANOPR. (See the ANOPR national 

impacts analysis (NIA) spreadsheet tool 

for cooktops and ovens on DOE’s Web 

site at: http://www1.eere.energy.gov/ 

buildings/appliance_standards/ 

residential/ 

cooking_products_anopr_tools.html). 

For Sabbath mode, in which the cooktop 

burners or heating elements must not be 

turned on, off, or adjusted during the 

Sabbath period, DOE estimates that the 

burners will be set at no more than 25 

percent of the heating input associated 

with active mode, due to safety 

considerations during such longduration use. Although the hours per 

mode presented in this table are 

estimates based on limited study data, 

DOE believes that energy patterns 

illustrated in this table are 

representative for most conventional 

cooktops, because Sabbath mode hours 

would be a small percentage of annual 

hours and the off/inactive power levels 

are based on DOE test measurements.

** 608 W (power in active mode) × 25 percent (percent of heating input that would be used during the Sabbath). 

For the same reasons as discussed for 

conventional ovens, DOE believes that 

Sabbath mode would be considered part 

of the active mode. Therefore, DOE is 

not proposing amendments to the 

conventional cooktop test procedure to 

define ‘‘Sabbath mode’’ or to measure 

power consumption. However, the 

comparison of annual energy 

consumption shows that energy use 

associated with Sabbath mode is 

insignificant, because only a small 

number of hours are associated with this 

mode. DOE instead proposes to allocate 

the Sabbath mode hours (which total 2.1 

hours for this example case) to the 

active mode (which would total 213.2 

hours in this example case). 

As with conventional ovens, DOE 

believes there are few conventional 

cooktops with electronic controls that 

have an additional mechanical off 

switch. Therefore, DOE proposes that 

the combined inactive/off mode hours 

would likely be allocated fully either to 

inactive or off mode, depending on the 

type of controls present on the 

conventional cooktop. For conventional 

cooktops for which both inactive mode 

and off mode are present, DOE proposes 

to allocate half of the non-active hours 

each to inactive and off modes. DOE 

welcomes comment and additional 

information on the proposed approach 

for calculating energy use for standby 

and off modes, including the decision to 

allocate all non-active mode hours to off 

and inactive modes. 

In summary, DOE proposes to 

determine conventional cooktop energy 

use associated with standby mode and 

off mode by: (1) Calculating the product

of wattage and allocated hours for all 

possible standby and off modes; (2) 

summing the results; and (3) dividing 

the sum by 1,000 to convert from Wh to 

kWh. DOE invites comments on this 

proposed methodology and associated 

factors, including accuracy, allocation of 

annual hours, and test burden. 

c. Conventional Ranges 

DOE investigated the hours and 

energy consumption associated with 

each possible operating mode for 

conventional ovens, including inactive, 

Sabbath, delay start, cycle finished, off, 

and active mode. 

DOE notes that RECS only provides 

usage data for conventional ovens and 

does not provide usage data for 

conventional ranges. As discussed 

previously, DOE estimated based on the 

2005 RECS that there are 211 active 

mode cooking cycles per year for 

conventional ovens, resulting in 211 

active mode hours per year. DOE also 

estimated that a conventional cooktop is 

in the active mode for 211 hours per 

year. DOE believes that the annual 

hours that a conventional range would 

be in active mode would be the sum of 

the annual active mode hours for 

conventional ovens and cooktops, 

which equals 422 hours. Since a range 

is essentially a combination of an oven 

and a cooktop, DOE’s rationale is to 

combine the average values for these 

two components individually. 

Therefore, for conventional ranges, DOE 

proposes to associate 422 hours with 

active mode, and the remaining 8,338 

hours of the year with the other nonactive modes. DOE welcomes 

information and data on such average 

cycle times, as well as annual 

conventional range usage. RECS does 

provide consumer usage data on how 

many conventional ranges are used per 

household. Based on its analysis of the 

2005 RECS data, DOE estimates that 

1.03 conventional ranges are used per 

household. 

DOE is not aware of reliable consumer 

usage data for hours spent in different 

standby and off modes for conventional 

ranges. DOE estimated the time 

associated with Sabbath mode in 

conventional ranges based on the 

percentage of Jewish households in the 

United States that observe kosher 

practices at home (the households 

expected to use Sabbath mode), the 

number of annual work-free days, and 

the number of conventional ranges used 

per household. DOE believes this 

represents the population of consumers 

which uses Sabbath mode features in a 

conventional range. As was determined 

earlier for conventional ovens, DOE 

estimates that about 0.54 percent of U.S. 

households keep kosher homes. As was 

estimated for conventional ovens, DOE 

estimates 1,584 annual work-free hours 

(i.e., the weekly Sabbath and the annual 

Jewish holidays). Applying these 

estimates to the number of ranges per 

household, as estimated earlier in this 

section, DOE estimates that 8.8 hours 

per year would be associated with 

Sabbath mode for conventional ranges. 

The calculation is as follows: 0.54 

percent (percent of U.S. households that 

observe kosher practices) × 1,584 hours 

(annual work-free hours per year) × 1.03 

(conventional ranges per household) = 

8.8 hours per year. 

DOE analyzed a DOE survey of ranges 

currently available on the market and 

estimated that 79 percent of 

conventional ranges are equipped with 

a delay start function.31 DOE notes that 

conventional ranges available on the 

market may offer a delay start function 

of up to 24 hours. As it did for 

conventional ovens, DOE estimates this 

function will be used on only 50 percent 

of conventional ranges so equipped. 

DOE also estimates that consumers who 

use the delay start function will use it 

for 5 percent of the cooking cycles 

associated with the oven portion of the 

range and set it for a 12-hour delay start 

period. (The 12-hour period is half of 

the maximum delay start time available 

on conventional ranges.) Applying these 

estimates to all conventional ranges and 

applying DOE’s estimate of 211 oven 

cooking cycles per year, DOE estimates 

that the average time a conventional 

range is operating in delay start mode 

per cycle is 14.2 minutes, or (14.2 

minutes × 211 cycles per year) = 50 

hours per year. 

To estimate the annual time 

associated with cycle finished mode, 

DOE assumes that, on average, 

conventional ranges remain in cycle 

finished mode for 5 minutes after every 

cycle, resulting in (5 minutes × 211 

cycles per year) = 18 annual hours 

associated with cycle finished mode. 

The remaining 8,261.2 annual hours 

not associated with active, Sabbath, 

delay start, or cycle finished mode are 

allocated to off and inactive modes 

(8,760 annual hours ¥ 422 active mode 

hours ¥ 8.8 Sabbath mode hours ¥ 50 

delay start mode hours ¥ 18 cycle 

finished mode hours). The hours for the 

relevant modes and estimates of power 

input and energy use are summarized in 

Table III.8. The approximate wattages 

associated with each mode, other than 

active mode, were determined from 

internal testing conducted by DOE on 21 

conventional ranges.32 For active mode, 

the typical average power level is based 

on the sum of the typical power levels 

for conventional ovens and cooktops, as 

shown in Table III.6 and Table III.7. 

While the hours per mode presented in 

this table are estimates based on limited 

study data, DOE believes that energy 

patterns illustrated in Table III.8 are 

representative for most conventional 

ranges because Sabbath mode hours 

would be reasonably a small percentage 

of annual hours and the non-active 

power levels are based on DOE test 

measurements.

Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 75313 

** 79 percent (percentage of conventional ovens with delay start function) × 50 percent (percentage of machines for which the delay start function is used) × 5 percent (for consumers that use the delay start function, the percentage of cycles that the consumer would use this function) × 

12 hours (average programmed duration of delay start period) × 211 (annual oven portion cooking cycles) = 50 hours. † 211 (annual oven portion cooking cycles) × 5 minutes (estimated cycle finished minutes per cycle) = 18 hours. †† 171 kWh (annual energy use for conventional ovens) + 128.2 kWh (annual energy use for conventional cooktops) = 299.2 kWh. 

As discussed for conventional ovens, 

DOE believes delay start mode would 

not be considered part of standby mode, 

because it is not a mode which may 

persist indefinitely. Instead, DOE 

believes delay start mode to be a form 

of active mode. Therefore, DOE is not 

proposing amendments to the 

conventional range test procedure to 

define ‘‘delay start mode’’ or to measure 

power consumption in this mode. 

However, the comparison of annual 

energy consumption of different 

conventional oven ranges shows that 

energy use associated with delay start 

mode is relatively insignificant because 

only a small number of hours are 

associated with this mode. In addition, 

the power levels in this mode are 

similar to those for off/inactive modes 

for conventional ranges currently on the 

market. For this reason, DOE proposes 

to allocate delay start mode hours 

(which total 50 hours for this example 

case) to the inactive and off modes 

(which would then total 8,367.5 hours 

in this example case). 

Also, as discussed for conventional 

ovens, DOE believes that Sabbath mode 

would be considered part of the active 

mode for conventional ranges because, 

in this mode, the automatic shutoff for 

the oven is overridden to allow for 

warming of pre-cooked foods during 

such periods as the Jewish Sabbath. 

Therefore, DOE is not proposing 

amendments to the conventional 

cooking products test procedure to 

define ‘‘Sabbath mode’’ or to measure 

power consumption in this mode. 

However, the comparison of annual 

energy consumption shows that energy 

use associated with Sabbath mode is 

insignificant because only a small 

number of hours are associated with this 

mode. DOE instead proposes to allocate 

the Sabbath mode hours (which total 

8.8 hours for this example case) to the 

active mode hours (which would then 

total 430.8 hours in this example case.) 

To determine the annual hours per 

mode for conventional ranges for which 

not all standby modes are possible, DOE 

estimated values by reallocating the 

hours for modes that are not present 

using the allocations discussed 

previously. If cycle finished mode, 

which is assumed to be a fixed value of 

18 hours per year, is not possible, the 

off/inactive mode hours would be 8,760 

total hours ¥ 430.8 active mode hours 

= 8,329.2 hours. If cycle finished mode 

is possible, the off/inactive mode hours 

would be 8,760 total hours ¥ 430.8 

active mode hours ¥ 18 cycle finished 

hours = 8,311.2 hours. 

Also, for the same reasons as 

discussed for conventional ovens, DOE 

proposes that, in most cases, the 

combined inactive/off mode hours 

would be allocated fully either to 

inactive or off mode, depending on the 

type of controls present on the 

conventional range. However, for 

conventional ranges for which both 

inactive mode and off mode are present, 

DOE proposes to allocate half of the 

non-active hours to inactive mode and 

the other half to off mode. DOE 

welcomes comment and additional 

information on the proposed approach 

for calculating energy use for standby 

mode and off mode, including the 

decision to allocate all non-active mode 

hours to off and inactive modes. 

In summary, DOE proposes to 

determine conventional range energy 

use associated with standby mode and 

off mode by: (1) Calculating the product 

of wattage and allocated hours for all 

possible standby and off modes; (2) 

summing the results; and (3) dividing 

the sum by 1,000 to convert from Wh to 

kWh. DOE invites comments on this 

proposed methodology and associated 

factors, including accuracy, allocation of 

annual hours, and test burden. DOE may 

also consider adoption in the final rule 

of the following alternative 

methodology based on comments 

received. 

The comparison of annual energy use 

of different conventional range modes 

shows that cycle finished mode 

represents a relatively small number of 

hours at a low power consumption 

level. For conventional ranges currently 

on the market, these levels are distinct 

from but comparable to those for off/ 

inactive mode. Thus, DOE could adopt 

an approach that would be limited to 

specifying the hours for only off/ 

inactive mode when calculating energy 

use associated with standby and 

inactive/off modes. In that case, all of 

the non-active hours (8,329.2 hours 

total) would be allocated to the inactive/ 

off mode. DOE invites comment on 

whether such an alternative would be 

representative of the standby mode and 

off mode power consumption of 

conventional ranges currently on the 

market. 

F. Measures of Energy Consumption 

Under 42 U.S.C. 6295(gg)(2)(A), EPCA 

directs that when DOE amends its test 

procedures to include standby mode 

and off mode energy consumption for a 

covered product, DOE shall integrate 

such energy consumption into the 

overall energy efficiency, energy 

consumption, or other energy descriptor 

for each covered product, unless the 

Secretary determines that: (i) The 

current test procedures for a covered 

product already fully account for and 

incorporate the standby mode and off 

mode energy consumption of the 

covered product; or (ii) such an 

integrated test procedure is technically 

infeasible for a particular covered 

product, in which case the Secretary 

shall prescribe a separate standby mode 

and off mode energy use test procedure, 

if technically feasible. 

In considering whether it is 

technically feasible to integrate standby 

mode and off mode energy use into a 

combined metric along with active 

mode energy use, DOE makes a case-bycase determination for the product in 

question. One general principle which 

DOE considers in making such 

determination is whether any mode of 

energy use would be so large as to 

overwhelm the other for standardsetting purposes. Although it may be 

possible to measure energy use in each 

mode with a substantial degree of 

precision, in some cases there may be 

very large differences in energy use in 

active mode versus standby/off modes, 

such that the effects of the lesser mode 

would not be reflected within the 

precision of the regulatory metric. In 

such cases, DOE believes that disparities 

in levels of energy use between the 

different modes may be so great that a 

combined metric would not be 

technically feasible, so a separate metric 

for standby mode and off mode would 

be warranted. In contrast, where the 

standby mode and off mode energy use 

is of a magnitude that it would 

materially affect that standard-setting 

process without overwhelming the 

effects of differing levels of active mode 

energy use, a combined metric would be 

meaningful and will be adopted as 

required by the EISA 2007 amendments 

to EPCA. 

DOE analyzed whether the existing 

measures of energy consumption for 

dishwashers, dehumidifiers, and 

conventional cooking products can be

33The drying energy consumption for 

dishwashers is the energy consumed using the 

power-dry feature after the termination of the last 

rinse option of the normal cycle. 

combined with standby mode and off 

mode energy use to form a single metric. 

DOE’s tentative conclusions resulting 

from this inquiry are presented below. 

1. Dishwashers 

The DOE test procedure for 

dishwashers currently incorporates 

various measures of energy and water 

consumption. These include per-cycle 

machine electrical energy consumption, 

per-cycle energy consumption from 

drying dishes after termination of the 

last rinse cycle, per-cycle water 

consumption, per-cycle water heating 

energy consumption (for electricallyheated, gas-heated, or oil-heated water), 

and annual standby energy 

consumption. (See 10 CFR part 430, 

subpart B, appendix C, sections 5.1, 5.2, 

5.4, and 5.6 for details.) The test 

procedure also provides a calculation 

for EAEU, EAOC, and EF. The current 

standards are based on EAEU, which 

incorporates a simplified measure of 

standby energy consumption. (10 CFR 

430.32(f)(2)) 

Because the dishwasher test 

procedure already combines measures 

of active mode energy consumption and 

standby mode energy use to derive an 

overall ‘‘energy efficiency measure,’’ 

DOE believes it is technically feasible to 

incorporate standby mode and off mode 

energy consumption into the overall 

energy efficiency descriptor, which is 

the EAEU. Furthermore, DOE notes that 

the analysis of overall energy use for 

dishwashers presented in section III.E 

shows that the standby mode and off 

mode energy use is of a magnitude that 

it would materially affect that standardsetting process without overwhelming 

the effects of differing levels of active 

mode energy use . Therefore, a 

combined measure of energy efficiency 

for dishwashers is a meaningful 

measure. As discussed in section III.B, 

DOE is proposing amendments to the 

testing methods to fully account for 

standby mode and off mode energy 

consumption for dishwashers. Because 

it is proposing those amendments, DOE 

also proposes to amend the calculation 

of EAEU to incorporate the revised 

measures of standby mode and off mode 

energy consumption. The revised EAEU 

metric would satisfy the EPCA 

requirement to integrate standby mode 

and off mode energy consumption into 

the overall energy consumption metric. 

(42 U.S.C. 6295(gg)(2)(A)) 

As noted in section I, EPCA requires 

that DOE must determine to what 

extent, if any, a proposed test procedure 

would alter the measured energy 

efficiency of any covered product as 

determined under the existing test 

procedure. (42 U.S.C. 6293(e)(1)) The 

current DOE dishwasher test procedure 

defines ‘‘standby mode’’ as the ‘‘lowest 

power consumption mode which cannot 

be switched off or influenced by the 

user * * *’’ 10 CFR part 430, subpart B, 

appendix C, section 1.14. DOE is 

proposing to measure an additional 

standby mode (i.e., cycle finished 

mode). However, the proposed 

amendments would clarify that the 

provisions related to the new measures 

of energy consumption in standby mode 

and off mode would not be required to 

be used by manufacturers until the 

compliance date of any amended 

dishwasher standards addressing 

standby mode and off mode energy use. 

Therefore, the proposed amendments to 

the dishwasher test procedure regarding 

standby mode and off mode would not 

alter the measured efficiency of any 

covered product under the existing test 

procedure. 

As part of the final rule for the DOE 

dishwasher test procedure published in 

the Federal Register on August 29, 

2003, DOE also revised the test 

procedure to include standby energy use 

in the EAOC calculation, and DOE notes 

that this amendment was supported by 

interested parties. 68 FR 51887, 51892– 

93. Because the current dishwasher test 

procedure already incorporates standby 

energy use in the EAOC, DOE believes 

that it is technically feasible to 

incorporate both standby mode and off 

mode energy use into the EAOC. 

Therefore, DOE proposes to amend the 

EAOC calculation to incorporate the 

revised measures of standby mode and 

off mode energy consumption. 

The current dishwasher test 

procedure also includes a calculation of 

EF. EF is expressed in cycles per kWh 

and equals the inverse of the per-cycle 

machine electrical energy consumption 

minus half of the drying energy 

consumption.33 DOE notes that the 

current EF metric does not include 

standby mode energy use. For the final 

rule amending the dishwasher test 

procedure published on August 29, 

2003, DOE amended only the EAEU and 

EAOC calculations to include standby 

power consumption. DOE did not 

include standby power consumption in 

the EF calculation because, as defined 

in the test procedure, the EF: 

(1) Represents the amount of energy 

used during a cycle, and (2) standby 

power is energy consumed outside the 

wash cycle of a dishwasher and is, 

therefore, not a parameter in the EF 

calculation. 68 FR 51887, 51893. For 

these same reasons, and because the 

existing energy conservation standard is 

based on EAEU, DOE is not proposing 

changes to the EF calculation to include 

standby mode and off mode energy 

consumption. DOE expects that the 

annual energy use metric would 

continue to be the basis for energy 

conservation standards when they are 

next amended. 

The dishwasher test procedure 

currently provides instructions for 

rounding EAOC to the nearest dollar per 

year. 10 CFR 430.23(c)(1). However, no 

instructions are provided for rounding 

the final values of EF, EAEU, or water 

consumption per cycle (the latter two of 

which are the metrics for the current 

dishwasher energy conservation 

standards), nor the contributory 

measurements and interim calculations. 

This lack of specificity for rounding 

may lead to uncertainty in the reported 

metrics or to discrepancies among test 

laboratories for the same product, 

resulting in difficulty for regulated 

entities to ascertain, certify, and report 

compliance with the existing standards. 

Therefore, DOE proposes to add 

instructions to 10 CFR 430.23(c) 

requiring that EF be rounded to two 

decimal places, water consumption be 

rounded to one decimal place, and 

EAEU be rounded to the nearest whole 

kWh/year. 

2. Dehumidifiers 

The DOE test procedure for 

dehumidifiers currently only 

incorporates energy consumption in the 

form of EF (see 10 CFR part 430, subpart 

B, appendix X for details). EF, defined 

as liters of water removed from the air 

per kWh, is the metric for the current 

energy conservation standards for 

dehumidifiers. (10 CFR 430.32(v)) The 

current DOE test procedure for 

dehumidifiers does not account for 

standby mode and off mode energy use. 

As directed by EPCA, DOE analyzed 

whether standby mode and off mode 

energy consumption could be integrated 

into the overall energy efficiency metric. 

(42 U.S.C. 6295(gg)(2)(A)) DOE notes 

that the analysis of overall energy use 

for dehumidifiers presented in section 

III.E indicates the standby mode and off 

mode energy use is of a magnitude that 

it would materially affect that standardsetting process without overwhelming 

the effects of differing levels of active 

mode energy use. Therefore, a combined 

measure of energy efficiency for 

dehumidifiers is a meaningful measure. 

DOE proposes to establish the 

following measure of energy 

consumption for dehumidifiers. The 

integrated energy factor (IEF) measure 

accounts for the product’s energy use in 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 75315 

34The standby mode and off mode annual energy 

consumption is equivalent to the average standby 

mode and off mode power multiplied by the 

number of standby mode and off mode hours per 

year. 

35 ‘‘Energy factor’’ is defined as the ratio of the 

annual useful energy output to the total annual 

energy input. 

36 ‘‘Secondary cooking energy consumption’’ 

includes any electrical energy consumption of a 

conventional gas cooking product during active 

mode operation. 

37 DOE proposes to measure the standby mode 

and off mode energy consumption for a 

conventional range as a single product and to add 

the standby mode and off mode energy 

consumption separately in the calculation of the 

integrated annual energy consumption. It proposes 

this so that the standby mode and off mode power 

consumption is not measured separately for each 

component (i.e., cooktop and oven) and then 

summed with the cooking annual energy 

consumption, which would effectively double 

Continued 

standby mode and off mode, as well as 

the energy use of the product’s main 

functions. As discussed earlier, the 

current EF associated with 

dehumidifiers is calculated based on the 

liters of water removed from the air per 

kWh of energy consumed, as measured 

by a 24-hour test cycle. 10 CFR part 430, 

subpart B, appendix X, section 4. DOE 

notes that the calculation of EF 

represents the liters of water removed 

from the air per kWh of energy 

consumed over a given period of time, 

such as the number of active mode 

hours per year. If the ratio of the annual 

standby mode and off mode hours to the 

annual active mode hours is used to 

apportion standby mode and off mode 

power consumption over the active 

mode test period of one day, it is 

possible to calculate an IEF that 

incorporates both the efficiency of water 

removal from the air and the standby 

mode and off mode energy 

consumption. DOE proposes to calculate 

IEF using the following calculation: 

(The liters of water removed over the 

active mode test cycle)/((the active 

mode energy consumption over the 

active mode test cycle) + ((the standby 

mode and off mode annual energy 

consumption 34 × 24 hours)/(the active 

mode hours per year))). 

Section 3 of the current dehumidifier 

test procedure provides instructions for 

rounding EF to two decimal places. 

Section 3 also states that measurements 

be recorded at the resolution of the test 

instrumentation, and that calculations 

be rounded off to the same number of 

significant digits as the previous step. 

10 CFR part 30, subpart B, appendix X. 

DOE is proposing to retain these same 

instructions for EF in section 3.1 of the 

amended test procedure. DOE is also 

proposing to round the IEF value in 

section 5.2 to two decimal places. 

3. Conventional Cooking Products 

The DOE test procedures for 

conventional cooking tops, ovens, and 

ranges currently incorporate various 

measures of energy consumption. These 

include test energy consumption, 

annual cooking energy consumption, 

annual energy consumption of any 

continuously-burning pilot lights, 

annual self-cleaning energy 

consumption, annual clock energy 

consumption, total annual energy 

consumption, and cooking efficiency. 

(See 10 CFR part 430, subpart B, 

appendix I for details.) The test 

procedure also provides a calculation 

for EF 35 and EAOC. Although there are 

no current energy conservation 

standards based on performance for 

conventional cooking products (see 10 

CFR 430.32(j)), historically, DOE’s 

rulemaking analyses when considering 

standards have used EF as the energy 

conservation metric for conventional 

cooking products. 

DOE notes that the conventional 

cooking products test procedure 

currently combines measures of energy 

consumption and narrow forms of 

standby energy use, including 

continuously-operating clock and gas 

standing pilot light energy 

consumption, to derive an overall 

‘‘energy efficiency measure.’’ Therefore, 

a combined measure of energy 

efficiency for conventional cooking 

products has already been demonstrated 

to be a workable and meaningful 

measure. For this reason, DOE believes 

that it would be technically feasible to 

incorporate standby mode and off mode 

energy consumption into the overall 

energy efficiency descriptor (i.e., EF). 

Because DOE is proposing amendments 

to fully account for standby mode and 

off mode energy consumption for 

conventional cooking products, DOE 

proposes a combined metric addressing 

active, standby, and off modes for 

conventional cooking products, as 

explained in further detail below. 

DOE proposes to establish the 

following measures of energy 

consumption for conventional ovens. 

The measures integrate the product’s 

energy use in standby mode and off 

mode with energy use during main 

functions of the products. For 

conventional electric ovens, the 

‘‘integrated annual energy consumption’’ 

will be defined as the sum of the annual 

standby mode and off mode energy 

consumption, annual primary cooking 

energy consumption, and annual 

primary self-cleaning energy 

consumption, expressed in kWh. For 

conventional gas ovens that use 

electrical energy, the ‘‘integrated annual 

electrical energy consumption’’ will be 

defined as the sum of the annual 

standby mode and off mode energy 

consumption, annual secondary cooking 

energy consumption,36 and annual 

secondary self-cleaning energy 

consumption, expressed in kWh. For 

conventional electric ovens, IEF will be 

defined as the (annual useful cooking 

energy output)/(integrated annual 

energy consumption). For conventional 

gas ovens, IEF will be defined as the 

(annual useful cooking energy output)/ 

(annual gas energy consumption + 

integrated annual electrical energy 

consumption). DOE also proposes to 

include similar integrated annual energy 

consumption and IEF metrics for section 

4.1.2.6 of the cooking products test 

procedure regarding multiple 

conventional ovens (i.e., cooking 

appliances that include more than one 

conventional oven). 

DOE proposes to establish the 

following measures of energy 

consumption for conventional cooktops. 

The measures integrate the product’s 

energy use in standby mode and off 

mode with energy use during the main 

functions of the products. For 

conventional electric cooktops, the 

‘‘integrated annual energy consumption’’ 

will be defined as the (annual standby 

mode and off mode energy 

consumption) + (annual useful cooking 

energy output/conventional cooktop 

cooking efficiency), expressed in kWh. 

For conventional gas cooktops, the 

‘‘integrated annual electrical energy 

consumption’’ will be defined as the 

sum of the annual standby mode and off 

mode energy consumption, annual 

energy consumption for cooking, and 

annual energy consumption of the gas 

standing pilot light, expressed in kWh. 

For conventional electric cooktops, IEF 

will be defined as the annual useful 

cooking energy output divided by the 

electric cooktop integrated annual 

energy consumption. For conventional 

gas cooktops, IEF will be defined as the 

annual useful cooking energy output 

divided by the gas cooktop integrated 

annual energy consumption. 

DOE proposes to establish the 

following measures of energy 

consumption for conventional kitchen 

ranges (i.e., a cooktop and oven 

combined). The measures integrate the 

product’s energy use in standby mode 

and off mode with energy use during the 

main functions of the products. 

‘‘Integrated annual energy consumption’’ 

shall be the sum of the annual cooking 

energy consumption of each of its 

components plus the conventional range 

annual standby mode and off mode 

energy consumption.37 The IEF of a 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
75316 Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 

count the contribution of standby mode and off 

mode energy consumption. 

kitchen range shall be the sum of the 

annual useful cooking energy output of 

each component divided by the sum of 

the integrated annual energy 

consumption of each component. 

DOE is also proposing to amend the 

estimated annual energy cost 

calculations in 10 CFR 430.23(i) to 

include the cost of energy consumed in 

standby mode and off mode for 

conventional cooking products because, 

as noted above, the current cooking 

products test procedure already 

incorporates measures of narrow forms 

of standby energy use in the EAOC. 

Thus, DOE believes that it is technically 

feasible to incorporate both standby 

mode and off mode energy use into the 

EAOC and proposes to amend the EAOC 

calculations to incorporate the revised 

measures of standby mode and off mode 

energy consumption, thereby more 

accurately representing the unit’s 

EAOC. 

The cooking products test procedure 

currently provides instructions for 

rounding EAOC to the nearest dollar per 

year, and the cooking efficiency and 

energy factor to three significant digits. 

10 CFR 430.23(i)(1), (2), (4). DOE 

proposes to amend the test procedure to 

provide similar instructions requiring 

that EAOC based on total integrated 

annual electrical energy consumption be 

rounded to the nearest dollar per year 

and IEF to three significant digits. 

G. Compliance With Other EPCA 

Requirements 

1. Test Burden 

As noted previously, under 42 U.S.C. 

6293(b)(3), EPCA requires that ‘‘[a]ny 

test procedures prescribed or amended 

under this section shall be reasonably 

designed to produce test results which 

measure energy efficiency, energy use 

* * * or estimated annual operating 

cost of a covered product during a 

representative average use cycle or 

period of use * * * and shall not be 

unduly burdensome to conduct.’’ For the 

reasons that follow, DOE has tentatively 

concluded that amending the relevant 

DOE test procedures to incorporate 

clauses regarding test conditions and 

methods found in IEC Standard 62301 

(First Edition), along with the proposed 

modifications, would produce the 

required test results and would not 

result in any undue burdens. 

The proposed amendments to the 

DOE test procedures incorporate a test 

standard that is accepted internationally 

for measuring power consumption in 

standby mode and off mode. Based on 

its analysis of IEC Standard 62301 (First 

Edition), IEC Standard 62301 (CDV), 

and IEC Standard 62301 (FDIS), DOE 

has determined that the proposed 

amendments to the residential 

dishwashers, dehumidifiers, and 

conventional cooking products test 

procedures will produce standby mode 

and off mode average power 

consumption measurements that are 

representative of an average use cycle. 

These measures will be representative 

both when the measured power is stable 

and when it is unstable (i.e., when the 

measured power varies by 5 percent or 

more during the proposed 30-minute 

stabilization period.) Also, the test 

methods and equipment that the 

amendments would require for 

measuring standby mode and off mode 

power in these products are not 

substantially different from the test 

methods and equipment required in the 

current DOE tests. Thus, the proposed 

test procedure amendments would not 

require manufacturers to make 

significant investments in test facilities 

and new equipment. Therefore, DOE has 

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 procedure would not be unduly 

burdensome to conduct. 

2. Potential Incorporation of IEC 

Standard 62087 

Under 42 U.S.C. 6295(gg)(2)(A), EPCA 

directs DOE to consider IEC Standard 

62087 when amending test procedures 

to include standby mode and off mode 

power measurements. As discussed in 

section III.C of this notice, DOE 

reviewed IEC Standard 62087, ‘‘Methods 

of measurement for the power 

consumption of audio, video, and 

related equipment’’ (Second Edition 

2008–09), and has tentatively 

determined that it would not be 

applicable to measuring power 

consumption of electrical appliances 

such as dishwashers, dehumidifiers, 

and conventional cooking products. 

Therefore, DOE has tentatively 

concluded that referencing IEC Standard 

62087 is not necessary for the proposed 

amendments to the test procedures that 

are the subject of this rulemaking. 

3. Integration of Standby Mode and Off 

Mode Energy Consumption Into the 

Efficiency Metrics 

Under 42 U.S.C. 6295(gg)(2)(A), EPCA 

requires that standby mode and off 

mode energy consumption be 

‘‘integrated into the overall energy 

efficiency, energy consumption, or other 

energy descriptor for each covered 

product’’ unless the current test 

procedures already fully account for the 

standby mode and off mode energy 

consumption or if such an integrated 

test procedure is technically infeasible. 

For dishwashers, DOE proposes to 

incorporate the standby mode and off 

mode energy consumption into the test 

procedure’s calculation of ‘‘estimated 

annual energy use’’ and ‘‘estimated 

annual operating cost,’’ as discussed in 

section III.F. For dehumidifiers, DOE 

proposes to incorporate the standby 

mode and off mode energy consumption 

into an IEF metric, as discussed in 

section III.F. For conventional cooking 

products, DOE proposes to incorporate 

the standby mode and off mode energy 

consumption into an ‘‘integrated annual 

energy consumption,’’ an IEF, and 

‘‘estimated annual operating cost,’’ as 

discussed in section III.F of this notice. 

EPCA further provides that test 

procedure amendments adopted to 

comply with the new statutory 

requirements for standby mode and off 

mode energy consumption shall not be 

used to determine compliance with 

previously established standards. (42 

U.S.C. 6295(gg)(2)(C)) Under this 

provision, the test procedure 

amendments pertaining to standby 

mode and off mode energy consumption 

that DOE proposes to adopt in this 

rulemaking would not apply to, and 

would have no impact on, existing 

standards. 

Even though 42 U.S.C. 6295(gg)(2)(C) 

clearly states that the test procedure 

amendments for measurement of 

standby mode and off mode energy 

consumption shall not apply to existing 

standards, DOE must nonetheless 

determine the effect of such test 

procedure amendments on measured 

energy efficiency, measured energy use, 

or measured water use of any covered 

product, pursuant to 42 U.S.C. 

6293(e)(1). This analysis is provided 

below. However, no amendments to the 

energy conservation standards will be 

required pursuant to 42 U.S.C. 

6293(e)(2), because such test procedure 

amendments will not impact the 

existing energy conservation standards 

until the compliance date of a 

subsequent final rule that amends the 

standard to comprehensively address 

standby mode and off mode energy 

consumption. 

For dishwashers, the current energy 

conservation standards are based on 

EAEU, which includes standby mode 

power consumption. Because today’s 

proposed amendments would revise the 

calculations for EAEU and EAOC, both 

of which currently incorporate standby 

mode power to a limited extent, DOE 

investigated how the proposed 

amendments would affect the product’s 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 75317 

measured efficiency. DOE believes the 

proposed changes to the dishwasher 

testing methods for measuring standby 

mode and off mode energy consumption 

do not vary significantly from the 

methods currently in the DOE test 

procedure for measuring standby power 

and would not alter the measured 

efficiency. DOE also believes that the 

proposed revision to the definition of 

‘‘standby mode’’ would be unlikely to 

significantly affect the measured 

efficiency. Therefore, DOE believes that 

the proposed amendments to the 

dishwasher test procedure would not 

alter the measured efficiency. In 

addition, because the proposed 

amendments would clarify that 

manufacturers would not be required to 

use the provisions relating to standby 

mode and off mode energy use in the 

EAEU to determine compliance with the 

energy conservation standard until the 

compliance date of new dishwasher 

standard addressing standby mode and 

off mode energy use, the proposed test 

procedure amendments would not affect 

a manufacturer’s ability to demonstrate 

compliance with previously established 

standards for dishwashers. 

For dehumidifiers, existing energy 

conservation standards are based on EF, 

which would not be altered by the 

proposed test procedure amendments. 

In addition, DOE notes that the new 

combined measure of energy 

consumption (i.e., the integrated energy 

factor) which it is proposing would not 

affect the existing standard. However, 

the test procedure’s amended provisions 

for standby mode and off mode would 

be a requirement for demonstrating 

compliance with DOE’s energy 

conservation standards upon the 

effective date of a subsequent standards 

rulemaking for dehumidifiers that 

accounts for standby mode and off mode 

power consumption. Thus, the proposed 

test procedure amendments for 

dehumidifiers comply with these EPCA 

requirements. 

The current energy conservation 

standards for conventional cooking 

products are prescriptive standards 

which ban standing pilot lights. There 

are no current performance-based 

Federal energy conservation standards 

for conventional cooking products 

(including energy use in standby mode 

and off mode). Even so, the new 

combined measure of energy 

consumption (i.e., the integrated annual 

energy consumption) which DOE is 

proposing would not affect the existing 

annual energy consumption or EF 

metrics. The cooking products test 

procedure’s amended provisions for 

standby mode and off mode would be a 

requirement for demonstrating 

compliance with any new performancebased energy conservation standards 

upon the effective date of a subsequent 

standards rulemaking for conventional 

cooking products that accounts for 

standby mode and off mode power 

consumption. Thus, the proposed test 

procedure amendments for cooking 

products would not impact a 

manufacturer’s ability to certify 

compliance with existing requirements 

and, accordingly, comply with these 

EPCA requirements. 

H. Impact of the Proposed Amendments 

on EnergyGuide and ENERGY STAR 

DOE considered potential impacts of 

the proposed test procedure 

amendments to the Federal Trade 

Commission (FTC) EnergyGuide 

requirements and to the U.S. 

Environmental Protection Agency 

(EPA)/DOE ENERGY STAR voluntary 

labeling program and determined that 

there will be no impact. For 

dishwashers, the primary indication of 

energy use provided in the EnergyGuide 

label is EAEU and EAOC. In addition, 

the ENERGY STAR program for 

dishwashers is based on the EAEU and 

water consumption. As discussed in 

section III.G, DOE has clarified that the 

proposed amended calculations for 

dishwasher EAEU and EAOC shall be 

used for purposes other than 

demonstrating compliance with existing 

energy conservation standards, 

including the EnergyGuide and 

ENERGY STAR programs. Because, as 

also discussed in section III.G, the 

changes in EAEU and EAOC due to the 

proposed amendments are expected to 

be insignificant, DOE believes that there 

will be no measurable impact on these 

programs. For dehumidifiers, there are 

currently no FTC EnergyGuide labeling 

requirements, and the ENERGY STAR 

program is based on EF, which will not 

be changed by the proposed 

amendments. For conventional cooking 

products, there is currently no FTC 

EnergyGuide labeling requirement or 

ENERGY STAR voluntary labeling 

program. 

IV. Procedural Issues and Regulatory 

Review 

A. Review Under Executive Order 12866 

Today’s proposed rule action is not a 

‘‘significant regulatory action’’ under 

section 3(f) of Executive Order 12866, 

‘‘Regulatory Planning and Review,’’ 58 

FR 51735 (Oct. 4, 1993). Accordingly, 

this proposed action was not subject to 

review under the Executive Order by the 

Office of Information and Regulatory 

Affairs (OIRA) in the Office of 

Management and Budget (OMB). 

B. Review Under the Regulatory 

Flexibility Act 

The Regulatory Flexibility Act (5 

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

of an initial regulatory flexibility 

analysis for any rule that by law must 

be proposed for public comment, unless 

the agency certifies that the proposed 

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 

rulemaking process. 68 FR 7990. DOE’s 

procedures and policies may be viewed 

on the Office of the General Counsel’s 

Web site (http://www.gc.doe.gov). 

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 

prescribe test procedure amendments 

that would be used to determine 

compliance with energy conservation 

standards for the products that are the 

subject of this rulemaking. 

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 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/idc/ 

groups/public/documents/ 

sba_homepage/serv_sstd_tablepdf.pdf. 

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 335211, titled 

‘‘Electric Housewares and Household 

Fan Manufacturing,’’ is 750 employees; 

this classification specifically includes 

manufacturers of residential 

dehumidifiers. Finally, 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. 

Most of the manufacturers supplying 

residential dishwashers, dehumidifiers, 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
75318 Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 

and/or conventional cooking products 

are large multinational corporations. 

DOE surveyed the AHAM member 

directory to identify manufacturers of 

residential dishwashers, dehumidifiers, 

and conventional cooking products. 

DOE then consulted publicly-available 

data, purchased company reports from 

vendors such as Dun and Bradstreet, 

and contacted manufacturers, where 

needed, to determine if they meet the 

SBA’s definition of a ‘‘small business 

manufacturing facility’’ and have their 

manufacturing facilities located within 

the United States. Based on this 

analysis, DOE estimates that there are 

two small businesses that manufacture 

conventional cooking products and no 

small businesses that manufacture 

dishwashers or dehumidifiers. 

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 

dishwashers, dehumidifiers, and 

conventional cooking products by 

incorporating testing provisions to 

address standby mode and off mode 

energy consumption that will be used to 

develop and test compliance with future 

energy conservation standards. The test 

procedure amendments involve 

measuring power input when the 

dishwasher, dehumidifier, or 

conventional cooking product is in 

standby mode and off mode. These tests 

can be conducted in the same facilities 

used for the current energy testing of 

these products, but could also be 

conducted in separate facilities 

consisting of little more than 

temperature-controlled space, so there 

would be no additional facilities costs 

required by the proposed rule. In 

addition, while the power meter 

required for these tests might require 

greater accuracy than the power meter 

used for current energy testing, the 

investment required for a possible 

instrumentation upgrade would likely 

be relatively modest. It is possible that 

the manufacturers, or their testing 

facilities, already have equipment that 

meets the requirements of IEC Standard 

62301, but an Internet search of 

equipment that specifically meets the 

requirements of IEC Standard 62301 

reveals a cost of approximately $2,700 

to $3,000. This cost is small compared 

to the overall financial investment 

needed to undertake the business 

enterprise of testing consumer products 

which involves facilities, qualified staff, 

and specialized equipment. 

Furthermore, the duration of the 

standby mode and off mode testing is 

generally not expected to exceed the 

time required to conduct current energy 

testing. The requirements for equipment 

and time necessary to conduct the 

additional proposed tests are not 

expected to impose a significant 

economic burden on entities subject to 

the applicable testing requirements. 

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 

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 

This rule contains a collection-ofinformation requirement subject to the 

Paperwork Reduction Act (PRA) which 

has been approved by OMB under 

Control Number 1910–1400. Public 

reporting burden for compliance 

reporting for energy and water 

conservation standards is estimated to 

average 30 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. 

Send comments regarding this burden 

estimate, or any other aspect of this data 

collection, including suggestions for 

reducing the burden, to DOE (see 

ADDRESSES) and by e-mail to 

Christine_J._Kymn@omb.eop.gov. 

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 rulemaking, DOE proposes test 

procedure amendments that it expects 

would be used to develop and 

implement future energy conservation 

standards for residential dishwashers, 

dehumidifiers, and conventional 

cooking products. DOE has determined 

that this rule falls into a class of actions 

that are categorically excluded from 

review under the National 

Environmental Policy Act of 1969 (42 

U.S.C. 4321 et seq.) and DOE’s 

implementing regulations at 10 CFR part 

1021. Specifically, this proposed rule 

would amend the existing test 

procedures for these products without 

changing their environmental effects, 

and, therefore, it is covered by the 

Categorical Exclusion in 10 CFR part 

1021, subpart D, paragraph A5, which 

applies because this rule would 

establish revisions to existing test 

procedures that would not affect the 

amount, quality, or distribution of 

energy usage, and, therefore, would not 

result in any environmental impacts. 

Accordingly, neither an environmental 

assessment nor an environmental 

impact statement is required. 

E. Review Under Executive Order 13132 

Executive Order 13132, ‘‘Federalism,’’ 

imposes certain requirements on 

agencies formulating and implementing 

policies or regulations that preempt 

State law or that have Federalism 

implications. 64 FR 43255 (August 10, 

1999). 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 

that it will follow in developing such 

regulations. 65 FR 13735. DOE has 

examined this proposed rule and 

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 

upon criteria, set forth in EPCA. (42 

U.S.C. 6297(d)) Therefore, Executive 

Order 13132 requires no further action. 

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 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 75319 

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 clearly specifies the 

following: (1) The preemptive effect, if 

any; (2) any effect on existing Federal 

law or regulation; (3) a clear legal 

standard for affected conduct while 

promoting simplification and burden 

reduction; (4) the retroactive effect, if 

any; (5) definitions of key terms; and 

(6) 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 

whether it is unreasonable to meet one 

or more of them. DOE has completed the 

required review and determined that, to 

the extent permitted by law, this 

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) (Pub. L. 

104–4; 2 U.S.C. 1501 et seq.) requires 

each Federal agency to assess the effects 

of Federal regulatory actions on State, 

local, and Tribal governments and the 

private sector. 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 estimates of the resulting 

costs, benefits, and other effects on the 

national economy. (2 U.S.C. 1532(a), (b)) 

UMRA also requires a Federal agency to 

develop an effective process to permit 

timely input by elected officers of State, 

local, and Tribal governments on a 

proposed ‘‘significant intergovernmental 

mandate,’’ and requires an agency plan 

for giving notice and opportunity for 

timely input to potentially affected 

small governments before establishing 

any requirements that might 

significantly or uniquely affect such 

governments. On March 18, 1997, DOE 

published a statement of policy on its 

process for intergovernmental 

consultation under UMRA. 62 FR 

12820. (The policy is also available at 

http://www.gc.doe.gov.) Today’s 

proposed rule contains neither an 

intergovernmental mandate nor a 

mandate that may result in an 

expenditure of $100 million or more in 

any year, so these requirements do not 

apply. 

H. Review Under the Treasury and 

General Government Appropriations 

Act, 1999 

Section 654 of the Treasury and 

General Government Appropriations 

Act, 1999 (Pub. L. 105–277) requires 

Federal agencies to issue a Family 

Policymaking Assessment for any rule 

that may affect family well-being. 

Today’s proposed 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 

Pursuant to Executive Order 12630, 

‘‘Governmental Actions and Interference 

with Constitutionally Protected Property 

Rights,’’ 53 FR 8859 (March 18, 1988), 

DOE has determined that this proposed 

regulation would not result in any 

takings that might require compensation 

under the Fifth Amendment to the U.S. 

Constitution. 

J. Review Under the Treasury and 

General Government Appropriations 

Act, 2001 

Section 515 of the Treasury and 

General Government Appropriations 

Act, 2001 (Pub. L. 106–554; 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 notice 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 OIRA a Statement 

of Energy Effects for any proposed 

significant energy action. A ‘‘significant 

energy action’’ is defined as any action 

by an agency that promulgates 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 if the proposal is 

implemented, and of reasonable 

alternatives to the action and their 

expected benefits on energy supply, 

distribution, and use. Today’s proposed 

regulatory action to amend the test 

procedures for residential dishwashers, 

dehumidifiers, and conventional 

cooking products to address standby 

mode and off mode energy use is not a 

significant regulatory action under 

Executive Order 12866 or any successor 

order. It would not have a significant 

adverse effect on the supply, 

distribution, or use of energy. Moreover, 

it has not been designated by the 

Administrator of OIRA as a significant 

energy action. 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 DOE 

Organization Act (Pub. L. 95–91; 42 

U.S.C. 7101 et seq.), 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 (FEAA). (15 

U.S.C. 788) Section 32 essentially 

provides that, where a proposed rule 

authorizes or requires use of commercial 

standards, the 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 proposed modifications to test 

procedures addressed by this proposed 

rule incorporate testing methods 

contained in the commercial standard, 

IEC Standard 62301 ‘‘Household 

electrical appliances—Measurement of 

standby power.’’ DOE has evaluated this 

standard and is unable to conclude 

whether it fully complies with the 

requirements of section 32(b) of the 

FEAA (i.e., whether it was developed in 

a manner that fully provides for public 

participation, comment, and review). 

DOE will consult with the Attorney 

General and the Chairman of the FTC 

about the impact on competition of 

using the methods contained in this 

standard before prescribing a final rule.

E. Issues on Which DOE Seeks Comment 

Although comments are welcome on 

all aspects of this rulemaking, DOE is 

particularly interested in receiving 

comments and views of interested 

parties on the following issues: 

1. Incorporation of IEC Standard 

62301 (First Edition). DOE invites 

comment on the adequacy of IEC 

Standard 62301 (First Edition) to 

measure standby mode and off mode 

power consumption for residential 

dishwashers, dehumidifiers, and 

conventional cooking products, and the 

suitability of incorporating into DOE 

regulations the following specific 

provisions from IEC Standard 62301 

(First Edition): section 4 (‘‘General 

conditions for measurements’’), 

paragraph 4.2, ‘‘Test room,’’ paragraph 

4.4, ‘‘Supply voltage waveform,’’ and 

paragraph 4.5, ‘‘Power measurement 

accuracy,’’ and section 5 

(‘‘Measurements’’), paragraph 5.1, 

‘‘General,’’ and paragraph 5.3, 

‘‘Procedure.’’ (See section III.B) 

2. Mode definitions. DOE welcomes 

comment on the proposed definitions of 


emcdonald on DSK2BSOYB1PROD with PROPOSALS3
Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 75321 

‘‘standby mode,’’ ‘‘off mode,’’ and ‘‘active 

mode,’’ which are based on the 

definitions provided in IEC Standard 

62301 (FDIS). (See section III.C) 

3. Dishwasher standby and off modes. 

DOE invites comment on the proposed 

establishment of inactive mode and 

cycle finished mode as standby modes 

for dishwashers and the determination 

that ‘‘delay start mode’’ would not be 

considered a standby mode. DOE further 

invites comment as to whether there are 

any modes consistent with the ‘‘active 

mode,’’ ‘‘standby mode,’’ or ‘‘off mode’’ 

definitions that have not been identified 

in this NOPR and the extent to which 

these modes would represent significant 

energy use. (See section III.C) 

4. Dehumidifier standby and off 

modes. DOE invites comment on the 

proposed establishment of inactive 

mode, off-cycle mode, and bucket full/ 

removed mode as standby modes for 

dehumidifiers and the determination 

that ‘‘delay start mode’’ would not be 

considered a standby mode. DOE further 

invites comment as to whether there are 

any modes consistent with the ‘‘active 

mode,’’ ‘‘standby mode,’’ or ‘‘off mode’’ 

definitions that have not been identified 

in this NOPR and the extent to which 

these modes would represent significant 

energy use. (See section III.C) 

5. Conventional cooking products 

standby and off modes. DOE invites 

comment on the proposed establishment 

of inactive mode and cycle finished 

mode as standby modes for 

conventional cooking products and the 

determination that ‘‘delay start mode’’ 

and ‘‘Sabbath mode’’ would not be 

considered a standby mode. DOE further 

invites comment as to whether there are 

any modes consistent with the ‘‘active 

mode,’’ ‘‘standby mode,’’ or ‘‘off mode’’ 

definitions that have not been identified 

in this NOPR and the extent to which 

these modes would represent significant 

energy use. (See section III.C) 

6. Network mode. DOE welcomes 

comment on whether dishwashers, 

dehumidifiers, and conventional 

cooking products are currently available 

that incorporate a networking function 

and whether a definition for ‘‘network 

mode’’ and related testing procedures 

should be incorporated into the DOE 

test procedure. DOE also requests 

comment on appropriate methodologies 

for measuring energy consumption in a 

network mode for these products, and 

data on the results and repeatability of 

such testing methodology. (See section 

III.C) 

7. Default settings. DOE welcomes 

comment on the suitability of using 

product default settings in testing 

standby energy consumption, on any 

methodologies that can account for 

consumer actions that might increase 

energy use, and data on the repeatability 

of such testing procedures. (See section 

III.D) 

8. Test room ambient temperature. 

DOE seeks comment on the 

appropriateness of the proposed 

modified test room ambient temperature 

range for residential dishwashers, 

dehumidifiers, and conventional 

cooking products, which would allow 

manufacturers to conduct standby mode 

and off mode testing separately from 

performance testing under the less 

stringent ambient conditions specified 

in the IEC Standard 62301 (First 

Edition) (i.e., 73.4 ± 9 °F). (See section 

III.D) 

9. Test period. DOE seeks comment 

on whether a method in which the clock 

time on conventional cooking products 

would be set to 3:23 prior to a 10- 

minute stabilization period, followed by 

a 10-minute measurement period 

commencing at 3:33 would be an 

acceptable alternative to the method 

that DOE is proposing (i.e., a 10-minute 

initial stabilization period, after which 

the clock would be set to 3:23 and 

another 10-minute stabilization period 

provided before a 10-minute 

measurement starting at a clock time of 

3:33). DOE also requests comment on its 

proposed approach requiring results 

under the 12-hour test and the 10- 

minute test to be within ± 2 percent of 

each other and welcomes data which 

would show that some other range is 

more appropriate. 

10. Energy use calculation for standby 

mode and off mode. DOE invites 

comment on the approach for 

calculating total energy use for standby 

mode and off mode for dishwashers, 

dehumidifiers, and conventional 

cooking products. DOE also invites 

comment on the allocation of annual 

hours and test burden, as well as the 

alternative methodology for allocation 

of annual hours for each product. (See 

section III.E) 

11. New integrated measures of 

energy consumption and energy 

efficiency. DOE invites comment on the 

proposed plan to establish new 

integrated measures of energy 

consumption for dehumidifiers 

(‘‘integrated annual energy 

consumption’’) and conventional 

cooking products (‘‘integrated energy 

factor’’). DOE also invites comment on 

the proposed plan to modify the existing 

‘‘estimated annual energy use’’ for 

dishwashers and ‘‘estimated annual 

operating cost’’ metrics for dishwashers 

and conventional cooking products to 

incorporate the revised measurements of 

standby mode and off mode energy 

consumption. (See section III.F) 

VI. Approval of the Office of the 

Secretary 

The Secretary of Energy has approved 

publication of this notice of proposed 

rulemaking.

Appendix C to Subpart B of Part 430— 

Uniform Test Method for Measuring the 

Energy Consumption of Dishwashers 

Note: The procedures and calculations that 

refer to standby mode and off mode energy 

consumption (i.e., sections 4.5, 4.5.1 through 

4.5.3, and 5.7 of this Appendix C) need not 

be performed to determine compliance with 

energy conservation standards for 

dishwashers at this time. However, any 

representation related to standby mode and 

off mode energy consumption of these 

products made after May 31, 2011 must be 

based upon results generated under this test 

procedure using sections 4.5, 4.5.1 through 

4.5.3, and 5.7 and disregarding sections 4.4 

and 5.6, consistent with the requirements of 

42 U.S.C. 6293(c)(2). After July 1, 2010, any 

adopted energy conservation standard shall 

incorporate standby mode and off mode 

energy consumption, and upon the 

compliance date for such standards, 

compliance with the applicable provisions of 

this test procedure will also be required. 

1. Definitions

record a ‘‘true’’ average power as specified in 

Section 5, Paragraph 5.3.2(a) of IEC 62301. 

4. Test Cycle and Measurements 

* * * * * 

4.4 Simplified standby mode power. 

Connect the dishwasher to a standby 

wattmeter or a standby watt-hour meter as 

specified in sections 3.6 and 3.7, 

respectively, of this Appendix. Select the 

conditions necessary to achieve operation in 

the simplified standby mode as defined in 

section 1.17 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. 

4.5 Standby mode and off mode power. 

Connect the dishwasher to a standby mode 

and off mode watt meter as specified in 

sections 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 drop from a higher power 

state to a lower 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 of IEC 62301 for 

testing in each possible mode as described in 

sections 4.5.1 through 4.5.3 of this Appendix, 

except allowing the product to stabilize for 

at least 30 minutes and using an energy use 

measurement period of not less than 10 

minutes. For units in which power varies 

over a cycle, as described in Section 5, 

Paragraph 5.3.2 of IEC 62301, use the average 

power approach in Paragraph 5.3.2(a) of IEC 

62301, except allowing the product to 

stabilize for at least 30 minutes and using an 

energy use measurement period of not less 

than 10 minutes. 

4.5.1 If the dishwasher has an inactive 

mode, as defined in section 1.8, measure and 

record the average inactive mode power of 

the dishwasher, PIA, in watts. 

4.5.2 If the dishwasher has an off mode, 

as defined in section 1.11, measure and 

record the average off mode power, POFF, in 

watts. 

4.5.3 If the dishwasher has a cycle 

finished mode, as defined in section 1.5, 

measure and record the average cycle 

finished mode power, PCF, in watts.

Measurements 

* * * * * 

5.6 Annual simplified standby energy 

consumption. Calculate the estimated annual 

simplified standby energy consumption. First 

determine the number of standby hours per 

year, Hs, defined as: 

Hs = H ¥ (N × L) 

Where, 

H = the total number of hours per year = 8766 

hours per year, 

N = the representative average dishwasher 

use of 215 cycles per year, 

L = the average of the duration of the normal 

cycle and truncated normal cycle, for 

non-soil-sensing dishwashers with a 

truncated normal cycle; the duration of 

the normal cycle, for non-soil-sensing 

dishwashers without a truncated normal 

cycle; the average duration of the sensor 

light response, truncated sensor light 

response, sensor medium response, 

truncated sensor medium response, 

sensor heavy response, and truncated 

sensor heavy response, for soil-sensing 

dishwashers with a truncated cycle 

option; the average duration of the 

sensor light response, sensor medium 

response, and sensor heavy response, for 

soil-sensing dishwashers without a 

truncated cycle option. 

Then calculate the estimated annual 

simplified standby power use, S, expressed 

in kilowatt-hours per year and defined as: 

S = Sm × ((Hs)/1000) 

Where, 

Sm = the simplified standby mode power in 

watts as determined in section 4.4 of this 

Appendix. 

5.7 Standby mode and off mode annual 

energy consumption. Calculate the standby 

mode and off mode annual energy

75326 Federal Register / Vol. 75, No. 231 / Thursday, December 2, 2010 / Proposed Rules 

consumption for dishwashers, ETSO, 

expressed in kilowatt-hours per year, 

according to the following: 

ETSO = [(PIA × SIA) + (POFF × SOFF) + (PCF × 

SCF)] × K 

Where: 

PIA= dishwasher inactive mode power, in 

watts, as measured in section 4.5.1. 

POFF = dishwasher off mode power, in watts, 

as measured in section 4.5.2. 

PCF = dishwasher cycle finished mode power, 

in watts, as measured in section 4.5.3. 

If the dishwasher has both inactive mode 

and off mode, SIA and SOFF both equal STOT/ 

2; 

STOT equals the total number of inactive 

mode and off mode hours per year, defined 

as: 

If the dishwasher has cycle finished mode, 

STOT, in hours, equals HTSO ¥ SCF; 

If the dishwasher does not have cycle 

finished mode, STOT equals HTSO; 

HTSO equals the total number of standby 

mode and off mode hours per year, defined 

as: 

HTSO = H ¥ (N × L) 

Where, 

H = the total number of hours per year = 8766 

hours per year, 

N = the representative average dishwasher 

use of 215 cycles per year, 

L = the average of the duration of the normal 

cycle and truncated normal cycle, for 

non-soil-sensing dishwashers with a 

truncated normal cycle; the duration of 

the normal cycle, for non-soil-sensing 

dishwashers without a truncated normal 

cycle; the average duration of the sensor 

light response, truncated sensor light 

response, sensor medium response, 

truncated sensor medium response, 

sensor heavy response, and truncated 

sensor heavy response, for soil-sensing 

dishwashers with a truncated cycle 

option; the average duration of the 

sensor light response, sensor medium 

response, and sensor heavy response, for 

soil-sensing dishwashers without a 

truncated cycle option; 

If the dishwasher has an inactive mode but 

no off mode, the inactive mode annual hours, 

SIA, is equal to STOT and the off mode annual 

hours, SOFF, is equal to 0; 

If the dishwasher has an off mode but no 

inactive mode, SIA is equal to 0 and SOFF is 

equal to STOT; 

SCF = 237, dishwasher cycle finished mode 

annual hours; 

K = 0.001 kWh/Wh conversion factor for 

watt-hours to kilowatt-hours.

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, and 

conventional ovens at this time. However, 

any representation related to standby mode 

and off mode energy consumption of these 

products made after May 31, 2011 must be 

based upon results generated under this test 

procedure, consistent with the requirements 

of 42 U.S.C. 6293(c)(2). After July 1, 2010, 

any adopted energy conservation standard 

shall incorporate standby mode and off mode 

energy consumption, and upon the 

compliance date for such standards, 

compliance with the applicable provisions of 

this test procedure will also be required. 

Although microwave ovens are not currently 

included in this test procedure, future 

revisions may add relevant provisions for 

measuring active mode, standby mode, and 

off mode energy consumption in those 

products.

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 adjust any pilot lights of a 

conventional gas oven in accordance with the 

manufacturer’s instructions 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 1.9 and described in section 2.6. 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 at least 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.

conventional oven. Establish the test 

conditions set forth in Section 2, Test 

Conditions, of this Appendix. Adjust any 

pilot lights of a conventional gas oven in 

accordance with the manufacturer’s 

instructions and 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 1.9 and described in section 2.6. 

Then set the conventional oven’s selfcleaning process in accordance with the 

manufacturer’s instructions. If the selfcleaning process is adjustable, use the 

average time recommended by the 

manufacturer for a moderately soiled oven.

Appendix. For conventional ovens that drop 

from a higher power state to a lower power 

state as discussed in Section 5, Paragraph 5.1, 

Note 1 of IEC 62301 (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 of IEC 

62301 for testing in each possible mode as 

described in 3.1.1.3.1 through 3.1.1.3.3, 

except allowing the product to stabilize for 

at least 30 minutes and using an energy use 

measurement period not less than 10 

minutes. 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, and use the average power approach 

described in Section 5, Paragraph 5.3.2(a) of 

IEC 62301, 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, and 

use the average power approach described in 

Section 5, Paragraph 5.3.2(a) of IEC 62301, 

but with a single test period of 12 hours +0/ 

¥30 sec. Testing may be conducted using 

either a 12-hour test, a 10-minute test, or both 

tests; however, if a manufacturer elects to 

perform both tests on a unit, the 

manufacturer may only use the results from 

one of the test (i.e., the 12-hour test or the 

10-minute test) as the test results for that 

unit. Results of the 10-minute test that are 

within ± 2 percent of the 12-hour test are 

deemed to be representative of average 

energy use. 

3.1.1.3.1 If the conventional oven has an 

inactive mode, as defined in section 1.8, 

measure and record the average inactive 

mode power of the conventional oven, PIA, in

mm) or less in diameter. The large test block, 

W3, shall be used on electric surface units 

over 7 inches (178 mm) in diameter and on 

all gas surface units. Turn on the surface unit 

under test and set its energy input rate to the 

maximum setting. When the test block 

reaches 144 °F (80 °C) above its initial test 

block temperature, immediately reduce the 

energy input rate to 25±5 percent of the 

maximum energy input rate. After 15±0.1 

minutes at the reduced energy setting, turn 

off the surface unit under test.

with and without the forced convection 

mode: Measure the block temperature, TA, 

and the energy consumed, EA, or volume of 

gas consumed, VA, at the end of the last ‘‘ON’’ 

period of the conventional oven before the 

block reaches TO. Measure the block 

temperature, TB, and the energy consumed, 

EB, or volume of gas consumed, VB, at the

forced convection, measure in watt-hours (kJ) 

any electrical energy consumed by an 

ignition device or other electrical 

components required for the operation of a 

conventional gas oven while heating the test 

block to TO using the forced convection 

mode, (EIO)1, and without using the forced 

convection mode, (EIO)2.

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 

May 31, 2011 must be based upon results 

generated under this test procedure, 

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

6293(c)(2). After July 1, 2010, any adopted 

energy conservation standard shall 

incorporate standby mode and off mode 

energy consumption, and upon the 

compliance date for such standards, 

compliance with the applicable provisions of 

this test procedure will also be required. 

1. Scope 

This appendix covers the test requirements 

used to measure the energy performance of 

dehumidifiers. 

2. Definitions 

a. 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. 

b. 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. 

c. 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). 

d. IEC 62301 means the test standard 

published by the International 

Electrotechnical Commission, titled 

‘‘Household electrical appliances— 

Measurement of standby power,’’ Publication 

62301 (First Edition 2005–06) (incorporated 

by reference; see § 430.3). 

e. 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. 

f. 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. 

g. 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. 

h. 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. 

i. Standby mode means any modes where 

the dehumidifier is connected to a mains 

power source and offers one or more of the 

following user-oriented or protective 

functions which may persist for an indefinite 

time: 

(1) To facilitate the activation of other 

modes (including activation or deactivation 

of active mode) by remote switch (including 

remote control), internal sensor, or timer; 

(2) Continuous functions, including 

information or status displays (including 

clocks) or sensor-based functions. A timer is 

a continuous clock function (which may or 

may not be associated with a display) that 

provides regular scheduled tasks (e.g., 

switching) and that operates on a continuous 

basis. 

3. Test Apparatus and General Instructions 

3.1 Active mode. The test apparatus and 

instructions for testing dehumidifiers shall 

conform to the requirements specified in

Requirements for Dehumidifiers,’’ effective 

January 1, 2001 (incorporated by reference, 

see § 430.3). 

4.2 Standby mode and off mode. 

Establish the testing conditions set forth in 

section 3.2 of this Appendix. For 

dehumidifiers that drop from a higher power 

state to a lower power state as discussed in 

Section 5, Paragraph 5.1, Note 1 of IEC 

62301, (incorporated by reference; see 

§ 430.3), allow sufficient time for the 

dehumidifier to reach the lower power state 

before proceeding with the test measurement. 

Follow the test procedure specified in 

Section 5, Paragraph 5.3 of IEC 62301 for 

testing in each possible mode as described in 

sections 4.2.1 through 4.2.4 of this Appendix, 

except allowing the product to stabilize for 

at least 30 minutes and using an energy use 

measurement period of not less than 10 

minutes. For units in which power varies 

over a cycle, as described in Section 5, 

Paragraph 5.3.2 of IEC 62301, use the average 

power approach in Section 5, Paragraph 

5.3.2(a) of IEC 62301, except allowing the 

product to stabilize for at least 30 minutes 

and using an energy use measurement period 

of not less than 10 minutes. 

4.2.1 If the dehumidifier has an inactive 

mode, as defined in section 2(e) of this 

Appendix, measure and record the average 

inactive mode power of the dehumidifier, 

PIA, in watts. 

4.2.2 If the dehumidifier has an off-cycle 

mode, as defined in section 2(g) of this 

Appendix, measure and record the average 

off-cycle mode power of the dehumidifier, 

POC, in watts. 

4.2.3 If the dehumidifier has a bucket 

full/removed mode, as defined in section 2(b) 

of this Appendix, measure and record the 

average bucket full/removed mode power of 

the dehumidifier, PBFR, in watts. 

4.2.4 If the dehumidifier has an off 

mode, as defined in section 2(f) of this 

Appendix, measure and record the average 

off mode power, POFF, in watts. 

5. Calculation of Derived Results From Test 

Measurements 

5.1 Standby mode and off mode annual 

energy consumption. Calculate the standby 

mode and off mode annual energy 

consumption for dehumidifiers, ETSO,

expressed in kilowatt-hours per year, 

according to the following: 

ETSO = [(PIA × SIA) + (POC × SOC) + (PBFR × 

SBFR) + (POFF × SOFF)] × K 

Where: 

PIA = dehumidifier inactive mode power, in 

watts, as measured in section 4.2.1 of 

this Appendix. 

POC = dehumidifier off-cycle mode power, in 

watts, as measured in section 4.2.2 of 

this Appendix. 

PBFR = dehumidifier bucket full/removed 

mode power, in watts, as measured in 

section 4.2.3 of this Appendix. 

POFF = dehumidifier off mode power, in 

watts, as measured in section 4.2.4 of 

this Appendix. 

If the dehumidifier has an inactive mode 

and off-cycle mode but no off mode, the 

inactive mode annual hours, SIA, is equal to 

STOT/2; the off-cycle mode annual hours, SOC, 

is equal to STOT/2; and the off mode annual 

hours, SOFF, is equal to 0; 

STOT equals the total number of inactive 

mode, off-cycle mode, and off mode hours 

per year, defined as: 

If the dehumidifier has bucket full/ 

removed mode, STOT equals 3,024 hours; 

If the dehumidifier does not have bucket 

full/removed mode, STOT equals 3,681 hours; 

If the dehumidifier has an inactive mode 

and off mode but no off-cycle mode, the 

inactive mode annual hours, SIA, is equal to 

STOT/2; the off mode annual hours, SOFF, is 

equal to STOT/2; and the off-cycle mode 

annual hours, SOC, is equal to 0; 

If the dehumidifier has an inactive mode 

but no off-cycle mode or off mode, the 

inactive mode annual hours, SIA, is equal to 

STOT, and the off-cycle mode annual hours, 

SOC, and the off mode annual hours, SOFF, are 

each equal to 0; 

If the dehumidifier has an off-cycle mode 

and off mode but no inactive mode, the offcycle mode annual hours, SOC, is equal to 

STOT/2; the off mode annual hours, SOFF, is 

equal to STOT/2; and the inactive mode 

annual hours, SIA, is equal to 0; 

If the dehumidifier has an off-cycle mode 

but no off mode or inactive mode, the offcycle mode annual hours, SOC, is equal to 

STOT, and the off mode annual hours, SOFF, 

and the inactive mode annual hours, SIA, are 

each equal to 0; 

If the dehumidifier has an off mode but no 

inactive mode or off-cycle mode, the off 

mode annual hours, SOFF, is equal to STOT, 

and the inactive mode annual hours, SIA, and 

the off-cycle mode annual hours, SOC, are 

both equal to 0; 

If the dehumidifier has an inactive mode, 

off-cycle mode, and off mode, the inactive 

mode annual hours, SIA, is equal to STOT/3; 

the off-cycle mode annual hours, SOC, is 

equal to STOT/3; and the off mode annual 

hours, SOFF, is equal to STOT/3; 

SBFR = 657, dehumidifier bucket full/ 

removed mode annual hours; 

K = 0.001 kWh/Wh conversion factor for 

watt-hours to kilowatt-hours. 

5.2 Integrated energy factor. Calculate 

the integrated energy factor, IEF, expressed in 

liters per kilowatt-hour, rounded to two 

decimal places, according to the following: 

IEF = LW/(Eactive + ((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.
