Energy Conservation Program: Test 

Procedures for Residential 

Dishwashers, Dehumidifiers, and 

Conventional Cooking Products 

AGENCY: Office of Energy Efficiency and 

Renewable Energy, Department of 

Energy. 

ACTION: Final rule. 

SUMMARY: The U.S. Department of 

Energy (DOE) establishes new test 

procedures for residential dishwashers 

and dehumidifiers, and amends the 

currently applicable test procedure for 

conventional cooking products under 

the Energy Policy and Conservation Act. 

The new test procedures include 

provisions for measuring standby mode 

and off mode energy consumption, and 

update the provisions for measuring 

active mode energy consumption and, 

for dishwashers, water consumption. 

This final rule also amends the 

certification, compliance, and 

enforcement requirements for 

dishwashers, dehumidifiers and 

conventional cooking products, amends 

certain provisions in the currently 

applicable dishwasher test procedure, 

and eliminates an obsolete energy 

efficiency metric in the dishwasher test 

procedure and provisions in the cooking 

products test procedure that have 

become obsolete due to the elimination 

of standing pilot lights. 

DATES: Effective date: The effective date 

of this rule is December 17, 2012. 

Compliance Dates: The new test 

procedures for dishwashers and 

dehumidifiers and the final rule changes 

to the currently applicable test 

procedure for conventional cooking 

products will be mandatory to 

demonstrate compliance with the 

applicable energy conservation 

standards starting on the compliance 

date of any amended standards for 

dishwashers, dehumidifiers, and 

conventional cooking products. For 

dishwashers, this date will be May 30, 

2013, the compliance date of the direct 

final rule published on May 30, 2012, 

unless the direct final rule is withdrawn 

as a result of adverse comment. Use of 

the replacement items for obsolete 

dishware, flatware, and food items in 

the currently applicable dishwasher test 

procedure will be required on December 

17, 2012. Voluntary early use of the new 

dishwasher and dehumidifier test 

procedures and the final rule changes to 

the currently applicable test procedure 

for conventional cooking products to 

demonstrate compliance with 

applicable energy conservation 

standards or for representations of 

energy use (including the new standby 

mode and off mode provisions) is 

permissible on or after December 17, 

2012. 

The incorporation by reference of 

certain publications listed in this 

rulemaking is approved by the Director 

of the Office of the Federal Register as 

of December 17, 2012.

1The term ‘‘conventional cooking products,’’ as 

used in this notice, refers to residential electric and 

gas kitchen ovens, ranges, and cooktops (other than 

microwave ovens). 

2 DOE also considered IEC Standard 62087, which 

addresses the methods of measuring the power 

consumption of audio, video, and related 

equipment and is therefore not applicable to the 

products at issue in this rulemaking.

I. Authority and Background 

Title III of the Energy Policy and 

Conservation Act (42 U.S.C. 6291, et 

seq.; ‘‘EPCA’’ or, ‘‘the Act’’) sets forth a 

variety of provisions designed to 

improve energy efficiency. (All 

references to EPCA refer to the statute 

as amended through the Energy 

Independence and Security Act of 2007 

(EISA 2007), Public Law 110–140 (Dec. 

19, 2007)). Part B of title III, which for 

editorial reasons was redesignated as 

Part A upon incorporation into the U.S. 

Code (42 U.S.C. 6291–6309), establishes 

the ‘‘Energy Conservation Program for 

Consumer Products Other Than 

Automobiles.’’ These include residential 

dishwashers, dehumidifiers, and 

conventional cooking products,1 the 

subject of today’s final rule. (42 U.S.C. 

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

Under EPCA, this program consists 

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

labeling, (3) Federal energy conservation 

standards, and (4) certification and 

enforcement procedures. The testing 

requirements consist of test procedures 

that manufacturers of covered products 

must use as the basis for certifying to 

DOE that their products comply with 

the applicable energy conservation 

standards adopted under EPCA, and for 

making representations about the 

efficiency of those products. Similarly, 

DOE must use these test requirements to 

determine whether the products comply 

with any relevant standards 

promulgated under EPCA. 

A. General Test Procedure Rulemaking 

Process 

Under 42 U.S.C. 6293, EPCA sets forth 

the criteria and procedures DOE must 

follow when prescribing or amending 

test procedures for covered products. 

EPCA provides that any test procedures 

prescribed or amended under this 

section shall be reasonably designed to 

produce test results which measure 

energy efficiency, energy use or 

estimated annual operating cost of a 

covered product during a representative 

average use cycle or period of use and 

shall not be unduly burdensome to 

conduct. (42 U.S.C. 6293(b)(3)) 

In addition, if DOE determines that a 

test procedure amendment is warranted, 

it must publish proposed test 

procedures and offer the public an 

opportunity to present oral and written 

comments on them. (42 U.S.C. 

6293(b)(2)) Finally, in any rulemaking to 

amend a test procedure, DOE must 

determine to what extent, if any, the 

proposed test procedure would alter the 

measured energy efficiency of any 

covered product as determined under 

the existing test procedure. (42 U.S.C. 

6293(e)) 

EPCA, in relevant part, requires DOE 

to amend the test procedures for all 

residential covered products to include 

measures of standby mode and off mode 

energy consumption. Specifically, EPCA 

provides definitions of ‘‘standby mode’’ 

and ‘‘off mode’’ (42 U.S.C. 

6295(gg)(1)(A)) and permits DOE to 

amend these definitions in the context 

of a given product (42 U.S.C. 

6295(gg)(1)(B)). The statute requires 

integration of such energy consumption 

into the overall energy efficiency, 

energy consumption, or other energy 

descriptor for each covered product, 

unless the Secretary determines that— 

(i) The current test procedures for a 

covered product already fully account 

for and incorporate the standby mode 

and off mode energy consumption of the 

covered product; or 

(ii) such an integrated test procedure 

is technically infeasible for a particular 

covered product, in which case the 

Secretary shall prescribe a separate 

standby mode and off mode energy use 

test procedure for the covered product, 

if technically feasible. (42 U.S.C. 

6295(gg)(2)(A)) 

Any such amendment must consider 

the most current versions of IEC 

Standard 62301, ‘‘Household electrical 

appliances—Measurement of standby 

power,’’ and IEC Standard 62087, 

‘‘Methods of measurement for the power 

consumption of audio, video, and 

related equipment.’’ 2 Id. 

B. Summary of Current Test Procedures 

1. Dishwashers 

DOE’s test procedure for dishwashers 

is found in the Code of Federal 

Regulations (CFR) at 10 CFR part 430, 

subpart B, appendix C. DOE originally 

established its test procedure for 

dishwashers in 1977. 42 FR 39964 (Aug. 

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 

degrees Fahrenheit (°F) inlet water. 48 

FR 9202 (Mar. 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 (Aug. 

29, 2003). The current version of the test 

procedure includes provisions for 

determining estimated annual energy 

use (EAEU), estimated annual operating 

cost (EAOC), energy factor (EF) 

expressed in cycles per kilowatt-hour 

(kWh), and water consumption 

expressed in gallons per cycle. 10 CFR 

430.23(c). 

2. Dehumidifiers 

The DOE test procedure for 

dehumidifiers is found at 10 CFR part 

430, subpart B, appendix X. EPCA 

specifies that the dehumidifier test 

procedure must be based on the U.S.

program, see: www.energystar.gov. 4For more information on the EnergyGuide 

labeling program, see: www.access.gpo.gov/nara/ 

cfr/waisidx_00/16cfr305_00.html. 

5 DOE repealed its previous test procedure to 

measure the active mode energy use for microwave 

ovens after determining that the procedure did not 

procedure accurate and repeatable results. 75 FR 

42579 (July 22, 2010). 

6EISA 2007 directs DOE to also consider IEC 

Standard 62087 when amending its test procedure 

to include standby mode and off mode energy 

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

considered IEC Standard 62087 and determined 

that the standard addresses the methods of 

measuring the power consumption of audio, video, 

and related equipment and is therefore not 

applicable to the products addressed in today’s 

proposal. 

Environmental Protection Agency’s 

(EPA) test criteria used under the 

ENERGY STAR3 program unless revised 

by DOE. (42 U.S.C. 6293(b)(13)) The 

ENERGY STAR test criteria effective in 

January 2001 require that American 

National Standards Institute (ANSI)/ 

Association of Home Appliance 

Manufacturers (AHAM) Standard DH–1, 

‘‘Dehumidifiers,’’ be used to measure 

capacity and that the Canadian 

Standards Association (CAN/CSA) 

standard CAN/CSA–C749–1994 

(R2005), ‘‘Performance of 

Dehumidifiers,’’ be used to calculate EF. 

DOE adopted those test criteria, along 

with related definitions and tolerances, 

as its test procedure for dehumidifiers. 

71 FR 71340, 71347, 71366–68 (Dec. 8, 

2006). The DOE test procedure provides 

methods for determining the EF for 

dehumidifiers, which is expressed in 

liters (l) of water condensed per kWh. 

3. Conventional Cooking Products 

DOE’s test procedures for 

conventional ranges, cooktops, and 

ovens (including microwave ovens) are 

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 430 subpart B, 

appendix I. There is currently no 

EnergyGuide 4 labeling program for 

cooking products. 

With respect to today’s rulemaking, 

DOE issues a final rule amending its 

cooking products test procedure for 

conventional cooking products without 

addressing power consumption for 

microwave ovens. DOE is considering 

establishing a test procedure for active 

mode microwave oven energy use. (77 

FR 33106 (June 5, 2012)) 5 DOE has also 

initiated a separate test procedure 

rulemaking to address standby mode 

and off mode power consumption for 

microwave ovens. See 73 FR 62134 (Oct. 

17, 2008); 75 FR 42612 (July 22, 2010); 

76 FR 12825 (March 9, 2011) (hereafter 

referred to as the March 2011 Interim 

Final Rule). 76 FR 72332 (Nov. 23, 

2011); 77 FR 28805 (May 16, 2012). 

C. Summary of the Current Rulemaking 

1. The December 2010 NOPR 

On December 2, 2010, DOE published 

a Notice of Proposed Rulemaking 

(NOPR) (hereafter referred to as the 

December 2010 NOPR) in which it 

proposed to incorporate by reference 

into the test procedures for dishwashers, 

dehumidifiers, and conventional 

cooking products specific provisions 

from IEC Standard 62301 ‘‘Household 

electrical appliances—Measurement of 

standby power,’’ First Edition 2005–06 

(IEC Standard 62301 (First Edition) or 

‘‘First Edition’’) regarding test 

conditions and test procedures for 

measuring standby mode and off mode 

power consumption. 75 FR 75290, 

75295–97. DOE also proposed to 

incorporate into each test procedure 

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

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

definitions for those terms provided in 

the most current draft of an updated 

version of IEC Standard 62301. Id. at 

75297–300. Further, DOE proposed to 

include in each test procedure 

additional language that would clarify 

the application of clauses from IEC 

Standard 62301 (First Edition) for 

measuring standby mode and off mode 

power consumption.6 Id. at 75300–04. 

DOE held a public meeting on December 

17, 2010 (hereafter referred to as the 

NOPR Public Meeting) to receive 

comments on the December 2010 NOPR, 

and accepted written comments, data, 

and information until February 15, 

2011. Commenters to the December 

2010 NOPR suggested that the draft 

updated version of IEC Standard 62301 

would provide practical improvement to 

the mode definitions and testing 

methodology for the test procedures that 

are the subject of this rulemaking. 

2. The September 2011 Supplemental 

Notice of Proposed Rulemaking 

(SNOPR) 

The IEC adopted and published IEC 

Standard 62301, ‘‘Household electrical 

appliances—Measurement of standby 

power,’’ Edition 2.0 2011–01 (IEC 

Standard 62301 (Second Edition) or 

‘‘Second Edition’’) on January 27, 2011. 

DOE reviewed this latest version of the 

IEC standard and determined that it 

improves some measurements of 

standby mode and off mode energy use. 

Accordingly, DOE proposed in an 

SNOPR published in the Federal 

Register on September 20, 2011 (76 FR 

58346) (hereafter referred to as the 

September 2011 SNOPR), to incorporate 

certain provisions of the IEC Standard 

62301 (Second Edition), along with 

clarifying language, into the DOE test 

procedures for residential dishwashers, 

dehumidifiers, and conventional 

cooking products. Other than the 

specific amendments proposed in the 

September 2011 SNOPR, the test 

procedure amendments in the December 

2010 NOPR were not affected. 

3. The May 2012 SNOPR 

In response to comments received on 

the September 2011 SNOPR, DOE 

published an SNOPR on May 25, 2012 

(77 FR 31444) (hereafter referred to as 

the May 2012 SNOPR). DOE proposed to 

amend the dishwasher test procedure to 

remove an obsolete efficiency metric 

and to include measures of energy 

consumption in fan-only mode, 

measures of energy and water 

consumption due to periodic water 

softener regeneration, and clarified 

specifications for the normal cycle, 

power supply, energy test cycle, 

detergent dosing, and test load 

requirements. DOE also proposed 

amendments to the cooking products 

test procedure to measure energy 

consumption in conventional oven fanonly mode and remove obsolete 

provisions for gas pilot lights in the 

cooking products test procedure. For 

dehumidifiers, DOE proposed to update 

the industry test method specified in the 

test procedure. These proposals 

addressed comments received from 

interested parties in response to the 

December 2010 NOPR and September 

2011 NOPR, and incorporated methods 

provided in test procedure waivers 

granted by DOE for certain watersoftening dishwashers. (See 75 FR 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65945 

7The terms ‘‘obsolete’’ or ‘‘nearly obsolete’’ used 

in this context mean that the test load item, food 

item, or detergent is unavailable on the market or 

is available in such limited supply that it is not 

sufficiently available for testing purposes. 

8As stated in Section I, DOE is addressing test 

procedures for microwaves in separate rulemaking 

proceedings. 

62127 (Oct. 7, 2010) and 77 FR 33450 

(June 6, 2012)) 

4. The August 2012 SNOPR 

In response to comments received on 

the May 2012 SNOPR and during a 

public meeting held June 1, 2012 

(hereafter referred to as the 2012 Public 

Meeting), DOE published an SNOPR on 

August 15, 2012 (77 FR 49064) 

(hereafter referred to as the August 2012 

SNOPR) proposing to update certain 

obsolete dishware, flatware and food 

items used in the dishwasher test 

procedure; 7 amend the definition of the 

normal cycle, update the ambient 

temperature and preconditioning 

requirements; and update the referenced 

industry test method in the dishwasher 

test procedure. DOE also proposed to 

add water pressure, drain height, rack 

position, loading, rinse aid container, 

and soil preparation specifications to 

the dishwasher test procedure. DOE 

additionally proposed, for both 

dishwashers and cooking products, a 

revised test procedure to measure 

energy use in fan-only mode based on 

DOE analysis and comments received 

on the May 2012 SNOPR. 

II. Summary of the Final Rule 

In this final rule, DOE establishes new 

test procedures for residential 

dishwashers and dehumidifiers, and 

amends the test procedures for 

conventional cooking products, to 

incorporate by reference provisions 

from IEC Standard 62301 (Second 

Edition) for the measurement of energy 

use in standby mode and off mode, and, 

for dishwashers and conventional 

cooking products, methodology for the 

measurement of fan-only mode energy 

use, in the energy efficiency metrics. 

In the new dishwasher test procedure 

established in today’s final rule, DOE 

also: (1) Adds a measure of the annual 

energy and water use associated with 

periodic water softener system 

regeneration for those dishwashers 

equipped with such systems; and (2) 

incorporates by reference the updated 

industry test standard AHAM DW–1– 

2009, which upon acceptance by ANSI 

was designated as ANSI/AHAM DW–1– 

2010, American National Standard, 

‘‘Household Electric Dishwashers.’’ 

The final rule also clarifies in the new 

dishwasher test procedure: (1) The 

definitions of normal cycle, soil-sensing 

dishwasher, and non-soil-sensing 

dishwasher; (2) power supply 

requirements during testing; (3) energy 

test cycle requirements for soil-sensing 

dishwashers; (4) test load specifications 

and soiling requirements; (5) detergent 

dosing specifications; (6) rinse aid 

dosing specifications; and (7) length of 

time soils may sit before they are 

applied to dishware. 

The final rule also amends the testing 

conditions in the new dishwasher test 

procedure by: (1) Specifying the use of 

two pre-conditioning cycles to ensure 

the turbidity sensor is calibrated, (2) 

establishing maximum allowable time 

for the water pressure to reach the 

specified test conditions for improved 

repeatability and reproducibility, and 

(3) specifying drain height and rack 

position in the absence of 

manufacturer’s instructions to improve 

reproducibility. 

In today’s final rule, DOE also amends 

the current dishwasher test procedure to 

replace the obsolete flatware, dishware, 

and food items specified in the current 

test procedure with those proposed in 

Table 1 of the August 2012 SNOPR, 

except that the current cup and saucer 

and alternate fruit bowl specifications 

are retained and the product numbers 

are updated. The same replacement 

items are specified in the new 

dishwasher test procedure. 

The final rule also updates the 

industry test method specified in the 

new dehumidifier test procedure. As 

noted above, EPCA specifies that the 

dehumidifier test procedure must be 

based on EPA’s test criteria used under 

the ENERGY STAR program unless 

revised by DOE. (42 U.S.C. 6293(b)(13)) 

The ENERGY STAR test criteria 

effective in January 2001 require that 

ANSI/AHAM Standard DH–1, 

‘‘Dehumidifiers,’’ be used to measure 

energy use. DOE incorporates the most 

current version of the DH–1 standard 

(DH–1–2008) into the new test 

procedure for dehumidifiers. 

Finally, today’s final rule eliminates 

an obsolete metric from the dishwasher 

test procedure and provisions in the 

cooking products test procedure that 

have become obsolete due to the 

elimination of standing pilot lights. For 

cooking products, DOE eliminates 

measures of pilot light energy 

consumption from the test procedure. In 

a final rule published April 8, 2009, 

DOE established standards that prohibit 

constant-burning pilot lights in gas 

cooking products manufactured on or 

after April 9, 2012. 74 FR 16040. For 

dishwashers, DOE removes the 

calculation of EF from the dishwasher 

test procedure because the current 

dishwasher energy conservation 

standards no longer require it for 

compliance or representations. 

III. Discussion 

A. Products Covered by the Proposed 

Test Procedure Amendments 

The amendments adopted in today’s 

final rule to the DOE test procedures 

cover dishwashers, which DOE 

currently 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 amendments to the DOE test 

procedures also cover dehumidifiers, 

which DOE currently 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. 

Finally, today’s amendments to the 

DOE test procedures also cover cooking 

products, specifically conventional 

cooking products, which are currently 

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.8

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 did not propose any 

amendments to these definitions in the 

December 2010 NOPR, the September 

2011 SNOPR, the May 2012 SNOPR, or 

the August 2012 SNOPR. 

Whirlpool Corporation (Whirlpool) 

commented that the definitions of 

conventional cooking top, conventional 

oven, and conventional range should 

include electromagnetic induction as a 

means of cooking or heating, so that 

induction cooking products would be 

covered. (Whirlpool, No. 12 at p. 2) 9

DOE may consider amendments to its 

cooking products test procedure to 

address active, standby, and off mode 

energy use of induction cooking 

products in a separate rulemaking. 

BSH Home Appliances (BSH) asked 

how double ovens, microwave ovens, 

combination microwave ovens, and 

other combination products would be 

treated under this test procedure. (BSH, 

NOPR Public Meeting Transcript, No. 10 

at pp. 21–22) 10 DOE proposed in the 

December 2010 SNOPR that the 

integrated energy factor of combinations 

of ovens and cooktops other than a 

kitchen range (i.e., a cooktop and oven 

combined), which would include 

products with two conventional ovens, 

would be the sum of the annual useful 

cooking energy output of each 

component divided by the sum of the 

total integrated annual energy 

consumption of each component, 

according to calculations newly 

provided in the test procedure. 75 FR 

75290, 75333 (Dec. 2, 2010). DOE did 

not receive further comments or 

information regarding combination 

conventional cooking products, and this 

proposal was not affected by the 

subsequent SNOPRs. As discussed in 

Section I, DOE is addressing microwave 

ovens, including combination 

microwave ovens, in a separate 

rulemaking. 

In the absence of additional 

comments or input, DOE does not 

amend its current definitions of 

dishwasher, dehumidifier, conventional 

cooking product, conventional cooking 

top, conventional oven, or conventional 

range in today’s final rule. 

B. Compliance Date 

In the December 2010 NOPR, DOE 

proposed that the amended test 

procedures for residential dishwashers, 

dehumidifiers, and conventional 

cooking products would become 

effective 30 days after the test procedure 

final rule is published in the Federal 

Register. Any added procedures and 

calculations for standby mode and off 

mode energy consumption resulting 

from implementation of EISA 2007, 

however, would not need to be 

performed to determine compliance 

with the current energy conservation 

standards. Manufacturers would be 

required to use the 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 dishwashers, 

dehumidifiers, and conventional 

cooking products that address standby 

mode and off mode energy 

consumption. 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 would 

be required to be based upon results 

generated under the applicable 

provision of these test procedures, in 

accordance with 42 U.S.C. 6293(c)(2). 75 

FR 75290, 75294–95 (Dec. 2, 2010). 

In the May 2012 SNOPR, DOE 

proposed amendments clarifying the 

dishwasher test procedure that would 

apply on the effective date of the 

amended dishwasher test procedure 

(i.e., 30 days after the date of 

publication of the test procedure final 

rule in the Federal Register). 77 FR 

31444, 31450–52 (May 25, 2012). DOE 

also proposed methods by which the 

energy and water use of dishwasher 

water softener regeneration would be 

measured, as well as provisions to 

measure dishwasher and conventional 

cooking products fan-only mode energy 

consumption that would be required to 

be included in the energy efficiency 

metrics upon the compliance date of 

any updated dishwasher and 

conventional cooking product energy 

conservation standards addressing 

standby mode and off mode energy use. 

77 FR 31444, 31451 (May 25, 2012). In 

the August 2012 SNOPR, DOE proposed 

additional amendments to specify test 

load and soil items in place of obsolete 

or potentially obsolete items in the 

dishwasher test procedure that would 

be required 30 days after publication of 

the test procedure final rule in the 

Federal Register, and sought comment 

on whether the specified items could be 

procured in 30 days. (77 FR 49064, 

49065 (Aug, 15, 2012)). 

AHAM, BSH, Samsung Electronics 

America, Inc. (Samsung), and Whirlpool 

commented that DOE should clarify 

when the dishwasher test procedure 

amendments that could impact 

measured energy use, particularly the 

fan-only mode and water softener 

regeneration energy measurements, 

would be required for compliance with 

dishwasher energy conservation 

standards. These commenters stated that 

energy consumption in these modes 

should be included in the final metric 

to determine compliance with a future 

standard that has not yet been proposed, 

and not for compliance with the 

standard in the recent direct final rule. 

However, if these modes are included in 

the metric used to determine 

compliance with the standards in the 

direct final rule, the commenters stated 

that DOE must ensure that the 

stringency of the standards does not 

change. (AHAM, No. 20 at p. 3; AHAM, 

No. 27 at pp. 2–3; AHAM, No. 35 at p. 

2; BSH, No. 28 at p. 1; Samsung, No. 33 

at p. 1; Whirlpool, No. 26 at pp. 1–2) 

According to BSH, adequate time will 

be needed to test all the different base 

models using the amended dishwasher 

test procedure and to determine 

whether sensor decisions need to be 

changed, which may include adjusting 

software and conducting additional 

tests. BSH also stated that time should 

be allowed to use any parts in the 

supply chain before manufacturers are 

required to use the new test procedure. 

In addition, BSH stated that past 

accepted test data that were based on 

the previous test procedure should 

continue to be accepted until 

production ceases. (BSH, No. 36 at pp. 

1–2) 

The energy use of dishwasher water 

softener regeneration must be measured 

to demonstrate compliance with current 

energy conservation standards for 

dishwashers. In the test procedure 

waivers granted for water softening 

dishwashers, DOE has required that 

such models meet the current energy 

conservation standards with the 

additional energy and water use 

associated with water softener 

regeneration included in the annual 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65947 

energy use and per-cycle water 

consumption metrics. (75 FR 62127 

(Oct. 7, 2010) and 77 FR 33450 (June 5, 

2012)). In accordance with the approach 

specified in these waivers, DOE 

determines that the energy and water 

use must be included in the metrics 

used to demonstrate compliance with 

any amended dishwasher energy 

conservation standards, including those 

in the direct final rule. Compliance with 

the direct final rule will be required on 

May 30, 2013 unless the direct final rule 

is withdrawn as a result of adverse 

comment. 77 FR 31918 (May 30, 2012). 

DOE has determined that use of the 

test procedures to measure the energy 

use in fan-only mode on the compliance 

date of any amended standards is 

appropriate. Compliance with the 

dishwasher standards published on May 

30, 2012 will be required on May 30, 

2013 unless DOE withdraws the direct 

final rule. The energy use in these 

modes is estimated to be less than 5 

percent of the total energy use of 

standard dishwashers. Given that 65 

percent of all standard dishwashers 

currently on the market meet or exceed 

the minimum energy conservation 

standards established in the direct final 

rule, inclusion of this small amount of 

energy use would not impact 

compliance with the revised standard. 

77 FR 31918, 31948–31949. Therefore, 

DOE has determined that the energy use 

in fan-only mode is de minimus and 

insufficient to alter in a material manner 

the measured energy use of 

dishwashers. Therefore, DOE is not 

considering amending the standards set 

forth in the direct final rule. 

DOE is requiring that the 

clarifications to the dishwasher test 

procedure described in the May 2012 

SNOPR, which include the definition of 

the normal cycle, energy test cycle 

selection, power supply requirements, 

test load specifications and soiling 

requirements (except for the 

specification of replacement items for 

some obsolete dishware and flatware) 

and detergent dosing specifications, be 

used on the compliance date of any 

amended standards for dishwashers 

(May 30, 2013 unless the direct final 

rule is withdrawn). While DOE had 

earlier proposed that these requirements 

be mandatory 30 days after publication 

of the test procedure final rule in the 

Federal Register, DOE is adopting, as 

discussed below, amendments to the 

existing test procedure that specify 

replacement items for obsolete test load 

and soil items and technical corrections 

that will be required for use on or after 

45 days after publication of the test 

procedure final rule in the Federal 

Register. The remaining clarifications to 

the dishwasher test procedure, as well 

as the same specifications for 

replacement items, are provided in a 

new test procedure that will be required 

to be used on the compliance date of 

any amended standards for dishwashers 

(May 30, 2013 unless the direct final 

rule is withdrawn). 

For the replacement of obsolete items, 

DOE did not receive any comments 

regarding the proposed requirement for 

the use of certain test load and soil 

items in place of obsolete or potentially 

obsolete items in the dishwasher test 

procedure 30 days after publication of 

the test procedure final rule in the 

Federal Register, nor did it receive 

comment on whether the specified 

items could be procured in 30 days. 

Because certain test load items may 

require purchase outside of the United 

States, however, 30 days may not allow 

sufficient time for acquisition. DOE 

concludes, therefore, that requiring the 

use of replacement test load and soil 

items 45 days after the publication of 

the final rule best weighs the need for 

manufacturers and test laboratories to 

utilize comparable testing items against 

the timeframe potentially required for 

obtaining the items. 

In sum, with the exception of 

requirements for the use of replacement 

items for obsolete dishware, flatware, 

and food items specified as amendments 

to the current dishwasher test 

procedure, the final rule changes will be 

mandatory to demonstrate compliance 

with the applicable energy conservation 

standard starting on the compliance 

date of any amended standards for 

dehumidifiers, dishwashers, and 

cooking products, as required under 42 

U.S.C. 6295(s). For the amendments to 

the current dishwasher test procedure 

related to obsolete dishware, flatware, 

and food items, DOE has determined 

that use of these amended test 

procedure provisions would not alter a 

dishwasher’s measured energy 

efficiency or measured energy use 

pursuant to 42 U.S.C. 6293(e)(1). DOE 

has concluded that today’s final rule 

accords manufacturers with sufficient 

time to implement the test procedure 

changes contained herein. 

In summary, DOE establishes a new 

dishwasher test procedure at 10 CFR 

part 430, subpart B, appendix C1 that 

incorporates these final rule changes, 

including the use of replacement items. 

By amending the current test procedure 

to also include the use of replacement 

items, appendix C may continue to be 

used until the compliance date of 

amended dishwasher energy 

conservation standards. Similarly, DOE 

establishes a new dehumidifier test 

procedure at 10 CFR part 430, subpart 

B, appendix X1, but allows for the use 

of the current dehumidifier test 

procedure until the compliance date of 

amended dehumidifier energy 

conservation standards. Because the 

current energy conservation standards 

for conventional cooking products 

consist of a prescriptive design 

requirement prohibiting the use of 

constant-burning pilot lights, which do 

not require the use of the DOE test 

procedure to demonstrate compliance, 

DOE incorporates the final rule changes 

as amendments to the existing 

conventional cooking products test 

procedure codified at 10 CFR part 430, 

subpart B, appendix I. 

For dishwashers, the date upon which 

the use of new appendix C1 will be 

required will be May 30, 2013, the 

compliance date of the direct final rule 

published on May 30, 2012, unless the 

direct final rule is withdrawn. Until that 

date, manufacturers may continue to use 

appendix C to certify compliance with 

the current dishwasher energy 

conservation standards. Any products 

manufactured on or after that date must 

be certified to demonstrate compliance 

with the amended energy conservation 

standards using appendix C1. However, 

use of the replacement items for 

obsolete dishware, flatware, and food 

items in the amendments to the 

currently applicable dishwasher test 

procedure will be required on December 

17, 2012. 

Today’s final rule also clarifies that as 

of April 29, 2013, any representations 

related to the standby mode and off 

mode energy consumption of these 

products must be based upon results 

generated under the applicable 

provisions of appendix C1, appendix I, 

and appendix X1. Manufacturers may 

use the new dishwasher and 

dehumidifier test procedures and 

amended conventional cooking 

products test procedure prior to this 

date consistent with DOE guidance

C. Incorporation of IEC Standard 62301 

(Second Edition) for Measuring Standby 

Mode and Off Mode Power 

Consumption 

The December 2010 NOPR proposed 

to incorporate in the test procedures for 

dishwashers, dehumidifiers, and 

conventional cooking products relevant 

provisions from IEC Standard 62301 

(First Edition) for measuring standby 

mode and off mode power. The 

amended test procedures would use 

these measured wattages in calculations 

to incorporate standby mode and off

2011 Interim Final Rule until shortly before 

publication of the September 2011 SNOPR, DOE 

continued to include the cooking products mode 

definitions in this proposal. 

mode energy consumption into the test 

procedures. DOE reviewed the IEC 

Standard 62301 (First Edition) and 

tentatively concluded that it would be 

generally applicable to dishwashers, 

dehumidifiers, and conventional 

cooking products, although some 

clarification would be needed. 

Specifically, DOE proposed in the 

December 2010 NOPR for standby mode 

and off mode power measurements to 

provide a stabilization period of at least 

30 minutes followed by an energy use 

measurement period of not less than 10 

minutes for each of the covered 

products. 75 FR 75290, 75295–300 (Dec. 

2, 2010). Additionally, for conventional 

cooking products, DOE proposed a 

specific standby mode power 

measurement methodology for units in 

which power varies as a function of 

displayed time. 75 FR 75290, 75302–04 

(Dec. 2, 2010). With these clarifications, 

the December 2010 NOPR proposed to 

reference IEC Standard 62301 (First 

Edition) for the standby mode and off 

mode wattage measurements. DOE also 

proposed in the December 2010 NOPR 

to amend the dishwasher, dehumidifier, 

and conventional cooking products test 

procedures to include new definitions 

of ‘‘standby mode,’’ ‘‘off mode,’’ and 

‘‘active mode’’ based on the most 

current draft version of the Second 

Edition at that time (IEC Standard 62301 

(FDIS)). 75 FR 75290, 75296–97 (Dec. 2, 

2010). 

In response to comments on the 

December 2010 NOPR, and because IEC 

Standard 62301 (Second Edition) was 

issued on January 27, 2011, DOE 

evaluated in the September 2011 

SNOPR the applicability of the Second 

Edition for measuring standby mode 

and off mode energy use in the 

dishwasher, dehumidifier, and 

conventional cooking products test 

procedures. Commenters noted that IEC 

Standard 62301 (Second Edition) is an 

internationally-accepted test procedure 

for measuring standby power in 

residential appliances, and stated that 

they supported harmonizing the mode 

definitions with those in IEC Standard 

62301 (FDIS), which are substantively 

the same as those in IEC Standard 62301 

(Second Edition). 76 FR 58346, 58350 

(Sep. 20, 2011). DOE thus maintained in 

the September 2011 SNOPR the 

definitions for active mode, standby 

mode, and off mode that it had 

proposed in the December 2010 NOPR 

for dishwashers and dehumidifiers. 

The definitions for standby mode and 

off mode energy use for cooking 

products, as well as a slightly modified 

definition of active mode, were 

established in the cooking products test 

procedure by the March 2011 Interim 

Final Rule for microwave ovens. The 

definition of active mode established by 

the March 2011 Interim Final Rule 

includes the statement that delay start 

mode is a one-off, user-initiated, shortduration function that is associated with 

an active mode.11 The May 2012 SNOPR 

added reference to fan-only mode 

functions in active mode for 

dishwashers and cooking products. 

Detailed discussion of each of these 

mode definitions, including comments 

from interested parties, is presented in 

section III.D. 

DOE determined that the updated 

version of IEC Standard 62301 provides 

clarification to certain sections as 

compared to the First Edition. In 

particular, DOE proposed to incorporate 

by reference in the dishwasher, 

dehumidifier, and conventional cooking 

products test procedures the following 

provisions from IEC Standard 62301 

(Second Edition): (1) The room ambient 

air temperature requirements in section 

4, paragraph 4.2; (2) the electrical 

supply voltage requirements in section 

4, paragraph 4.3.2; (3) the power 

equipment specifications in section 4, 

paragraph 4.4; (4) the instructions for 

allowing the product to enter a lower 

power state prior to the test 

measurement in section 5, paragraph 

5.1, note 1; and (5) portions of the 

installation and setup procedures in 

section 5, paragraph 5.2. DOE also 

proposed that the measurement of 

standby mode and off mode power be 

made according to section 5, paragraph 

5.3.2 in each of the test procedures, 

except in the case of conventional 

cooking products in which power varies 

as a function of the clock time displayed 

in standby mode. For such products, 

DOE tentatively concluded that the 

application of the test methodology 

from the Second Edition would cause 

manufacturers to incur significant 

burden that would not be warranted by 

any potential improved accuracy of the 

test measurement. Thus, DOE 

maintained its original proposal from 

the December 2010 NOPR for 10-minute 

and 12-hour test methods for these 

products in the conventional cooking 

products test procedure, in which case 

testers would be allowed to choose 

measuring standby power by means of 

either of the following methods: 

(a) 10-Minute Test 

(1) Allow the product to stabilize 

according to section 5, paragraph 5.3 of 

IEC Standard 62301 (First Edition), 

which requires a minimum of 5 

minutes; 

(2) Set the clock time to 3:23; 

(3) Allow another stabilization period 

until the clock time reaches 3:33; 

(4) Use the average power approach in 

section 5, paragraph 5.3.2(a) to measure 

standby mode power for a period of 10 

minutes +0/¥2 seconds; or 

(b) 12-Hour Test 

(1) At any clock time, allow the 

product to stabilize according to section 

5, paragraph 5.3 of IEC Standard 62301 

(First Edition), which requires a 

minimum of 5 minutes; 

(2) Use the average power approach in 

section 5, paragraph 5.3.2(a) to measure 

standby mode power for a period of 12 

hours +0/¥30 seconds. 

According to the proposal, 

manufacturers could elect to conduct 

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

or both. Based on DOE testing, use of 

the 10-minute test period produced 

results that were within ±2 percent of 

the results for the full 12-hour test. 

Therefore, DOE proposed that, for 

verification and enforcement purposes, 

results of the 10-minute test that are 

within ±2 percent of the results for the 

12-hour test would be deemed to be 

representative of average energy use. 75 

FR 75290, 75302–304 (Dec. 2, 2010); 76 

FR 58346, 58349–53 (Sep. 20, 2011). 

The Appliance Standards Awareness 

Project (ASAP), American Council for 

an Energy Efficient Economy (ACEEE), 

and National Consumer Law Center 

(NCLC), jointly (hereafter referred to as 

the ‘‘SNOPR Joint Comment’’), AHAM, 

and Whirlpool support the 

incorporation by reference of IEC 

Standard 62301 (Second Edition). 

AHAM stated that the Second Edition 

contains important clarifications and 

would reduce test burden, while 

Whirlpool commented that the Second 

Edition provides more complete mode 

definitions and more robust 

measurements. AHAM and the SNOPR 

Joint Comment stated that the Second 

Edition would allow for international 

harmonization. (AHAM, No. 20 at pp. 

1–2; SNOPR Joint Comment, No. 22 at 

p. 1; Whirlpool, No. 21 at p. 2) 

DOE acknowledges the clarity and 

improvement in the measurement of 

standby mode and off mode power 

consumption through the use of IEC 

Standard 62301 (Second Edition), as 

well as the benefits of harmonization 

with international testing methods and 

the associated reduction in test burden 

for those manufacturers that sell 

products internationally by not 

requiring multiple standby power tests 

to be conducted according to different 

testing methods in different countries. 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65949 

12 In the preamble to the December 2010 NOPR, 

DOE discussed that the main function of producing 

heat may be used for cooking, heating, proofing, or 

holding the cooking load. Such specificity was not 

included in the proposed regulatory text in 

appendix I. 

For these reasons, in today’s final rule, 

DOE incorporates by reference into the 

new dishwasher and dehumidifier and 

amended conventional cooking 

products test procedures the previously 

noted provisions from IEC Standard 

62301 (Second Edition), including mode 

definitions, qualified as discussed in 

section 0 for the specific products, 

testing conditions, equipment, and 

methodology. 

DOE did not receive comments 

objecting to the proposed incorporation 

by reference of provisions from IEC 

Standard 62301 (First Edition) for 

standby mode power measurement for 

conventional cooking products with 

power consumption that varies as a 

function of the time displayed. DOE 

determines that the lower test burden 

for manufacturers is not warranted by 

any potential improved accuracy of the 

test measurement if the Second Edition 

were to be used. Therefore, DOE adopts 

in today’s final rule the average power 

method from IEC Standard 62301 (First 

Edition) for these products. 

D. Determination and Classification of 

Operational Modes 

1. Active Mode, Standby Mode, and Off 

Mode 

As noted previously, EPCA provides 

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

mode,’’ and ‘‘off mode’’ (42 U.S.C. 

6295(gg)(1)(A)) and permits DOE to 

amend these definitions in the context 

of a given product (42 U.S.C. 

6295(gg)(1)(B)). 

EPCA defines ‘‘active mode’’ as the 

condition in which an energy-using 

product: 

• Is connected to a main power 

source; 

• Has been activated; and 

• 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: 

• Is connected to a main power 

source; and 

• Offers one or more of the following 

user-oriented or protective functions: 

Æ To facilitate the activation or 

deactivation of other functions 

(including active mode) by remote 

switch (including remote control), 

internal sensor, or timer; 

Æ 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: 

• Is connected to a main power 

source; and 

• Is not providing any standby mode 

or active mode function. 

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

In the December 2010 NOPR, DOE 

discussed that the statutory definitions 

for ‘‘active mode,’’ ‘‘standby mode,’’ and 

‘‘off mode’’ were developed to be 

broadly applicable for many energyusing products. For specific products 

with multiple functions, these broad 

definitions could lead to multiple 

interpretations. Therefore, DOE 

proposed 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. 

a. Active Mode 

In the December 2010 NOPR, DOE 

proposed the following clarifications for 

the range of main functions that would 

be classified as active mode for each 

product: 

Dishwashers—‘‘Active mode’’ means 

a mode in which the dishwasher is 

connected to a mains power source, has 

been activated, and is performing the 

one of the main functions 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 connected to a mains power 

source, has been activated, and is 

performing the main function of 

producing heat 12 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. 75 FR 75290, 75297– 

98 (Dec. 2, 2010). 

For the September 2011 SNOPR, 

DOE’s proposal included a revised 

version of the active mode definition in 

the cooking products test procedure, 

based upon updates adopted by the 

March 2011 Interim Final Rule. 

Although that rulemaking addressed 

microwave ovens, the mode definitions 

in the test procedure at appendix I cover 

all cooking products, including 

microwave ovens and conventional 

cooking products. Therefore, in the 

September 2011 SNOPR, DOE proposed 

for cooking products that ‘‘active mode 

means a mode in which the product is 

connected to a mains power source, has 

been activated, and is performing the 

main function of producing heat by 

means of a gas flame, electric resistance 

heating, or microwave energy. Delay 

start mode is a one-off, user-initiated, 

short-duration function that is 

associated with an active mode.’’ 76 FR 

58346, 58363 (Sep. 20, 2011). 

Northwest Energy Efficiency Alliance 

(NEEA) agreed with DOE’s proposed 

definitions of active mode for each 

product. (NEEA, No. 11 at p. 2) 

Whirlpool also agreed with DOE’s 

proposed definition of active mode for 

dehumidifiers and conventional cooking 

products, provided that delay start is 

part of active mode. Whirlpool also 

agreed with DOE’s proposed definition 

of active mode for dishwashers as long 

as cycle finished mode is a part of active 

mode. (Whirlpool, No. 12 at p. 2) DOE 

evaluates delay start mode and cycle 

finished mode in the product-specific 

discussions in section III.D.2, and notes 

that the amendments adopted in today’s 

final rule provide for measurement of all 

active mode, standby mode, and off 

mode energy use, including delay start 

mode and cycle finished mode, in the 

dishwasher, dehumidifier, and 

conventional cooking products test 

procedures. 

As discussed in sections III.F.2 and 

III.F.3, DOE further proposed in the May 

2012 SNOPR that active mode for 

dishwashers would additionally include 

the functions of circulating air (fan-only 

mode) and regenerating a built-in water 

softening system. Therefore, DOE 

proposed a revised definition of active 

mode in the dishwasher test procedure 

that would include these functions. For 

cooking products, DOE proposed that 

circulating air in fan-only mode would 

be an active mode function, and 

accordingly proposed to add air 

circulation to the active mode functions. 

77 FR 31444, 31447–49, 31462 (May 25, 

2012). 


srobinson on DSK4SPTVN1PROD with 
65950 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

DOE did not receive comments 

objecting to the definitions of active 

mode for each of the covered products 

that were proposed in the May 2012 

SNOPR, Thus, in today’s final rule, DOE 

incoporates in the new dishwasher and 

dehumidifier test procedures and the 

amendments to the conventional 

cooking product test procedure the 

definition of active mode as proposed in 

the May 2012 SNOPR. 

b. Standby Mode 

DOE also proposed in the December 

2010 NOPR 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 user-oriented 

or protective functions which may 

persist for an indefinite time: 

• 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. 75 FR 75290, 75290 (Dec. 2, 

2010). 

In the December 2010 NOPR, DOE 

also proposed 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. Id. 

AHAM stated that it supported the 

standby mode definition based on IEC 

Standard 62301 (FDIS), although IEC 

Standard 62301 (Second Edition) should 

be the basis for the definition once the 

Second Edition was issued. AHAM and 

Whirlpool also requested that DOE 

require that all products default to the 

standby mode, as delivered from the 

factory. (AHAM, No. 14 at p. 3; AHAM, 

NOPR Public Meeting Transcript, No. 10 

at p. 36; Whirlpool, No. 12 at pp. 2, 4) 

DOE notes that its test procedures are 

used to measure the energy 

consumption of covered products in 

active, standby, and off modes, and do 

not prescribe specific operational 

characteristics for those products. 

DOE proposed in the December 2010 

NOPR to amend the ‘‘standby mode’’ 

definition in the dishwasher test 

procedure based on the definition 

provided in IEC Standard 62301 (FDIS), 

but also proposed to retain and 

redesignate the current DOE definition 

of standby mode for dishwashers as a 

‘‘simplified standby mode’’ to allow 

manufacturers to continue to use the 

existing standby mode provisions to 

determine compliance with the current 

dishwasher energy conservation 

standards until the compliance date of 

amended standards that address standby 

mode and off mode energy use. Id. 

Whirlpool commented that the 

retention of a simplified standby mode 

as a bridging step from the current DOE 

dishwasher test procedure is 

unnecessary. (Whirlpool, No. 12 at p. 2) 

In this final rule, DOE is retaining the 

existing methodology for measuring 

energy use in this ‘‘simplified standby 

mode’’ in appendix C. Use of the new 

standby mode provisions in appendix 

C1 will be required on May 30, 2013, 

unless the direct final rule published on 

May 30, 2012 is withdrawn. 

In the December 2010 NOPR, DOE 

proposed 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. Id. 

AHAM and NEEA supported DOE’s 

proposed definition of inactive mode. 

(AHAM, No. 14 at p. 4; NEEA, No. 11 

at p. 3) For the December 2010 NOPR, 

DOE derived the proposed mode 

definitions from IEC Standard 62301 

(FDIS), which were retained for IEC 

Standard 62301 (Second Edition). DOE 

retains this definition of inactive mode 

in this final rule. 

c. Off Mode 

In the December 2010 NOPR, DOE 

also proposed 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 

would be included within the 

classification of off mode. This 

definition of ‘‘off mode’’ was based on 

the definitions provided in IEC 

Standard 62301 (FDIS), and DOE stated 

that it would be useful in terms of 

expanding the scope of the EPCA mode 

definitions to clarify which functions 

are associated with off mode. 75 FR 

75290, 75299 (Dec. 2, 2010). 

Under these 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 

considered part of off mode. Id. 

NEEA supports the proposed 

definition of off mode for dishwashers, 

dehumidifiers, and conventional 

cooking products, to the extent that it is 

consistent with IEC Standard 62301. 

(NEEA, No. 11 at pp. 4–5) Whirlpool 

stated that the EPCA definition of off 

mode is adequate for each of these 

products. (AHAM, No. 12 at pp. 2–3) 

DOE determined that the definition of 

off mode that is consistent with the 

definition in IEC Standard 62301 

(Second Edition) is an important 

expansion to the EPCA definition that 

provides clarity for testing, and adopts 

in today’s final rule the proposed 

definition of off mode for the new 

dishwasher and dehumidifier test 

procedures and the amended 

conventional cooking products test 

procedure. 

AHAM and Whirlpool do not support 

classifying the energy use of a one-way 

remote control as part of standby mode, 

even though the EPCA definition of 

standby mode includes activation by 

means of remote control. According to 

these commenters, a standard remote 

that powers a product ‘‘off’’ actually 

powers the unit down, such that it can 

be turned on again through the use of 

the remote. A one-way remote does not 

put the product in standby mode; it only 

allows the product to be turned off. 

AHAM commented that there are few, if 

any, one-way remotes in the United 

States. AHAM believes that including 

one-way remotes in off mode instead of 

standby mode will encourage 

manufacturers to design products with 

one-way remotes, which could decrease 

energy use. (AHAM, No. 14 at p. 4; 

Whirlpool, No. 12 at p. 3) DOE agrees 

that once the one-way remote turns the 

product off, such that there is no 

standby function present and the unit 

cannot be returned to either active or 

standby mode by means of the remote, 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65951 

the unit would be considered to be 

operating in off mode. However, if the 

product is consuming energy without 

being in active mode while waiting for 

a signal from the one-way remote, the 

product would be classified as operating 

in standby mode because the remote 

would be available for deactivation of 

the main unit, regardless of whether 

other standby functions were present. 

Therefore, DOE clarifies that if energy is 

consumed by the appliance in the 

presence of a one-way remote control 

prior to turning the unit off from a nonactive mode, the unit would be 

considered to be operating in standby 

mode because the remote control would 

be used to deactivate other mode(s). 

Once the product is turned off by the 

one-way remote, it would be deemed to 

be operating in either standby mode or 

off mode, depending on the functions 

present in the appliance other than the 

remote control function, because the 

one-way remote would not be able to 

activate or deactivate other mode(s) at 

that point. 

2. Additional Product-Specific Modes 

In addition to the general mode 

definitions, DOE discussed in the 

December 2010 NOPR its analysis of 

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, as 

follows: 

a. Dishwashers 

In the December 2010 NOPR, DOE 

stated that it is aware of two additional 

relevant modes for dishwashers: (1) 

Delay start mode; and (2) cycle finished 

mode. ‘‘Delay start mode’’ would be 

defined as a mode in which activation 

of an active mode is facilitated by a 

timer. ‘‘Cycle finished mode’’ would be 

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, delay start 

mode would not be considered part of 

standby mode, but instead would be a 

form of active mode. DOE did not 

propose amendments to the dishwasher 

test procedure to define ‘‘delay start 

mode’’ or to measure power 

consumption in this mode. DOE stated 

that it may consider amendments 

addressing delay start mode issues in a 

future dishwasher test procedure 

rulemaking. 75 FR 75290, 75298 (Dec. 2, 

2010). 

Based on the ‘‘standby mode’’ 

definition proposed in the December 

2010 NOPR, cycle finished mode, which 

provides a continuous status display 

and may persist for an indefinite time, 

would be considered as part of a 

standby mode. Therefore, DOE proposed 

in the December 2010 NOPR to define 

cycle finished mode for dishwashers as 

‘‘a mode which provides continuous 

status display following operation in 

active mode.’’ Id. For the May 2012 

SNOPR, DOE also identified fan-only 

mode for dishwashers (77 FR 31444, 

31447–49 (May 25, 2012)), which is 

discussed separately in section III.F.2 of 

this notice, as well as dishwasher water 

softener regeneration (77 FR 31444, 

31449–50 (May 25, 2012)), which is 

discussed in section III.F.3 of this 

notice. 

ASAP, ACEEE, NCLC, and Natural 

Resources Defense Council (NRDC), 

jointly (hereafter referred to as the 

‘‘NOPR/SNOPR2 Joint Comment’’), 

Southern California Edison, Southern 

California Gas Company, and San Diego 

Gas and Electric Company, jointly 

(hereafter the ‘‘California Utilities’’), 

AHAM, NEEA, Pacific Gas and Electric 

Company (PG&E), and Whirlpool agree 

with DOE’s proposal that delay start 

mode should be classified as a form of 

active mode. AHAM supported DOE’s 

decision not to propose amendments to 

the dishwasher test procedure to 

measure energy use in delay start mode, 

while the California Utilities, the NOPR/ 

SNOPR2 Joint Comment, and PG&E 

stated that DOE should include 

measures of delay start mode energy use 

in the dishwasher test procedure. The 

NOPR/SNOPR2 Joint Comment believes 

that if energy consumption in delay start 

mode is not measured, manufacturers 

will have no incentive to reduce it. 

(AHAM, No. 14 at p. 5; AHAM, NOPR 

Public Meeting Transcript, No. 10 at p. 

41; California Utilities, No. 16 at p. 2; 

NEEA, No. 11 at p. 2; NOPR/SNOPR2 

Joint Comment, No. 13 at pp. 2–3; 

PG&E, No. 17 at p. 2; Whirlpool, No. 12 

at p. 2) DOE retains the classification of 

delay start mode as part of active mode 

for dishwashers in today’s final rule. 

Although DOE is not adopting specific 

provisions to measure energy use in 

delay start mode alone, DOE is 

including provisions in the dishwasher 

test procedure at appendix C1 to 

measure the energy use in all low-power 

modes combined, which includes 

modes other than the active washing 

and drying cycle, fan-only mode, and 

water softener regeneration. (See section 

III.F.1). 

AHAM and Whirlpool disagree with 

DOE’s proposal to classify cycle 

finished mode for dishwashers as a 

standby mode. According to Whirlpool, 

any function begun by the user when 

initiating the active mode includes all 

power consumed until the full 

conclusion of that operation. Whirlpool 

stated that cycle-finished mode actions 

include vent opening/closing, a signal to 

the consumer that the dishes are clean, 

or other modest users of energy. 

Whirlpool believes that establishing a 

separate cycle finished mode adds 

complications and cost to the 

dishwasher test procedure without any 

corresponding improvement in energy 

consumption or value to the consumer. 

(AHAM, No. 14 at p. 5; AHAM, NOPR 

Public Meeting Transcript, No. 10 at pp. 

41–42; Whirlpool, No. 12 at p. 2) NEEA 

stated that DOE should define cycle 

finished mode as the portion of the 

active mode between the end of the 

active washing mode and the beginning 

of the inactive mode. However, NEEA 

interpreted cycle finished mode to mean 

the period in which a fan operates after 

the end of the active washing and 

drying cycle. NEEA noted that after the 

fan run time, the dishwasher reverts to 

a status display (inactive) mode that 

will persist indefinitely until the user 

opens the door. NEEA believes that the 

status display (inactive) mode is a 

standby mode. NEEA further 

commented that if DOE defines such a 

status display mode as ‘‘cycle finished 

mode,’’ that the cycle finished period of 

some specified average duration should 

be added to the active mode test 

procedure. (NEEA, No. 11 at pp. 2–3) 

DOE notes that in its proposals, it 

narrowly defined cycle finished mode 

for dishwashers as providing 

continuous status display following 

operation in active mode. Because the 

function specified in this definition is a 

status display that may persist for an 

indefinite time until the user opens the 

door, cycle finished mode for 

dishwashers would be classified as a 

standby mode under the general 

definition of ‘‘standby mode’’ adopted 

in today’s final rule for the new 

dishwasher test procedure. DOE has 

also determined that any period of fan 

operation after the end of the active 

washing and drying cycle would be 

classified as a ‘‘fan-only mode’’ that is 

part of active mode. As discussed in 

section III.F.2 of today’s final rule, DOE 

includes in the new dishwasher test 

procedure provisions to measure the 

energy use in fan-only mode if the 

dishwasher is capable of such operation. 

In today’s final rule, DOE also adds 

definitions of cycle finished mode and 

fan-only mode to the dishwasher test 

procedure to aid the tester in 

differentiating these modes and to 

clarify that the energy use in cycle 

finished mode is included in the 


srobinson on DSK4SPTVN1PROD with 
65952 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

combined low-power energy use 

measurement, as discussed in section 

III.F.1 of this notice. 

b. Dehumidifiers 

In the December 2010 NOPR, DOE 

stated that it is aware of three additional 

relevant modes for dehumidifiers: (1) 

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

and (3) bucket full/removed mode. DOE 

proposed that the definition for ‘‘delay 

start mode’’ for dehumidifiers would be 

the same as that for dishwashers. ‘‘Offcycle mode’’ would be 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’’ would be 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, delay start mode would 

not be considered a standby mode, but 

instead would be a form of active mode. 

DOE did not propose in the December 

2010 NOPR amendments to define or to 

measure power consumption in delay 

start mode. DOE stated that it may 

consider amendments addressing delay 

start mode issues in a future 

dehumidifier test procedure rulemaking. 

75 FR 75290, 75298 (Dec. 2, 2010). 

DOE discussed in the December 2010 

NOPR 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. 

DOE proposed amending its 

dehumidifier test procedure to include 

definitions of ‘‘off-cycle mode’’ and 

‘‘bucket full/removed mode.’’ 75290, 

75298–99 (Dec. 2, 2010). 

The NOPR/SNOPR2 Joint Comment, 

the California Utilities, AHAM, NEEA, 

PG&E, and Whirlpool agree with DOE’s 

proposal that delay start mode should 

be classified as a form of active mode for 

dehumidifiers. AHAM supported DOE’s 

decision not to propose amendments to 

the dehumidifier test procedure to 

measure energy use in delay start mode. 

The California Utilities, the NOPR/ 

SNOPR2 Joint Comment, and PG&E 

stated that DOE should include 

measures of delay start mode energy use 

in the dehumidifier test procedure. The 

NOPR/SNOPR2 Joint Comment stated 

that if energy consumption in delay start 

mode is not measured, manufacturers 

will have no incentive to reduce it. 

(AHAM, No. 14 at p. 5; AHAM, NOPR 

Public Meeting Transcript, No. 10 at p. 

45; California Utilities, No. 16 at p. 2; 

NEEA, No. 11 at p. 2; NOPR/SNOPR2 

Joint Comment, No. 13 at pp. 2–3; 

PG&E, No. 17 at p. 2; Whirlpool, No. 12 

at p. 2) DOE maintains this 

determination that delay start mode is 

part of active mode for dehumidifiers in 

today’s final rule. DOE includes 

provisions in the new dehumidifier test 

procedure to measure the energy use in 

all low-power modes combined, which 

includes all modes other than active 

dehumidification mode (i.e., delay start 

mode, bucket full/removed mode, 

inactive mode, off-cycle mode, and off 

mode.) (See section III.F.1). 

Several commenters objected to DOE’s 

proposed classification of bucket full/ 

removed mode as a standby mode. GE 

Consumer & Industrial (GE) and NEEA 

consider bucket full/removed mode as a 

cycle finished mode, and while it may 

persist for an indefinite period of time, 

it is associated with the active mode 

cycle, much like the dishwasher cycle 

finished mode. NEEA further stated that 

DOE should consider bucket full/ 

removed mode as the portion of the 

active mode between the end of the 

active cycle and the beginning of the 

inactive mode when the user empties 

and/or replaces the bucket. (GE, NOPR 

Public Meeting Transcript, No. 10 at p. 

45; NEEA, No. 11 at pp. 3–4) Whirlpool 

and AHAM also consider bucket full/ 

removed mode to be part of active 

mode. (Whirlpool, No. 12 at p. 2; 

AHAM, No. 14 at p. 5) However, in the 

event that DOE retains bucket full/ 

removed mode as a standby mode, 

AHAM suggested that the definition of 

bucket full/removed mode should 

clarify that the dehumidifier has 

automatically powered off its main 

function by detecting when the water 

bucket is full or has been removed, and 

does not have its fan or blower 

operating. (AHAM, No. 14 at p. 5) 

DOE agrees that the bucket full/ 

removed mode can be associated with 

the active mode function in which 

moisture is removed from the air and 

collected in the bucket. However, 

bucket full/removed mode can also 

occur when the bucket is removed, 

regardless of whether the dehumidifier 

was actively removing moisture or 

circulating air at the time the bucket 

was removed. For example, the bucket 

may be removed during off-cycle mode, 

which is a standby mode. In addition, 

bucket full/removed mode may persist 

indefinitely with a continuous status 

display and no main function, which 

would meet the definition of a standby 

mode. DOE maintains its determination 

that bucket full/removed mode is a 

standby mode for today’s final rule. 

DOE agrees that the fan or blower shall 

not be operating during bucket full/ 

removed mode, because such operation 

would result in the dehumidifier 

circulating air as part of active mode, 

but does not adopt a definition of bucket 

full/removed mode in the new 

dehumidifier test procedure because 

bucket full/removed mode energy use is 

included in the combined measurement 

of all low-power mode energy use. 

Whirlpool agreed with DOE’s 

proposal to classify off-cycle mode as a 

standby mode. (Whirlpool, No. 12 at p. 

2) In today’s final rule, DOE includes 

the proposed definition of off-cycle 

mode in appendix X1, and includes offcycle mode in the measurement of 

energy use in the combined low-power 

modes. 

c. Conventional Cooking Products 

DOE stated in the December 2010 

NOPR that it 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’’ would be the same as 

defined for dishwashers. ‘‘Sabbath 

mode’’ would be defined as a mode in 

which the automatic shutoff is 

overridden to allow for warming of precooked foods during such periods as the 

Jewish Sabbath. 

For the same reasons as discussed for 

dishwashers and dehumidifiers, delay 

start mode would not be considered a 

standby mode, but instead would be a 

form of active mode. In addition, the 

Sabbath mode function of warming food 

would also be considered part of the 

active mode. DOE did not propose in 

the December 2010 NOPR amendments 

to define or to measure power 

consumption in ‘‘delay start mode’’ or 

‘‘Sabbath mode.’’ DOE stated that it may 

consider amendments addressing delay 

start mode and Sabbath mode issues in 

a future cooking products test procedure 

rulemaking 75 FR 75290, 75299 (Dec. 2, 

2010). 

DOE discussed in the December 2010 

NOPR 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. DOE proposed to 

amend its conventional cooking 

products test procedure to include a 

definition of ‘‘cycle finished mode.’’ 75 

FR 75290, 75299 (Dec. 2, 2010). For the 

May 2012 SNOPR, DOE also identified 

fan-only mode for conventional cooking 

products, which is discussed in section 

III.F.2 of this notice. 

The NOPR/SNOPR2 Joint Comment, 

the California Utilities, AHAM, NEEA, 

PG&E, and Whirlpool commented that 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65953 

13 In the December 2010, DOE proposed to 

allocate the 8.9 estimated annual Sabbath mode 

hours to the active cooking mode. 75 FR 75290, 

75309–10 (Dec. 2, 2010). 

delay start mode should be considered 

part of active mode for conventional 

cooking products. The California 

Utilities, the NOPR/SNOPR2 Joint 

Comment, and PG&E stated that DOE 

should include measures of delay start 

mode energy use in the test procedure. 

The NOPR/SNOPR2 Joint Comment 

believes that if energy consumption in 

delay start mode is not measured, 

manufacturers will have no incentive to 

reduce it. (AHAM, No. 14 at p. 5; 

AHAM, NOPR Public Meeting 

Transcript, No. 10 at p. 46; California 

Utilities, No. 16 at p. 2; NEEA, No. 11 

at p. 2, NOPR/SNOPR2 Joint Comment, 

No. 13 at pp. 2–3; PG&E, No. 17 at p. 

2; Whirlpool, No. 12 at p. 2) NEEA and 

Whirlpool also agree with DOE that 

Sabbath mode is part of active mode. 

(NEEA, No. 11 at p. 4; Whirlpool, No. 

12 at p. 3) 

For the reasons discussed in section 

III.F.1 of this notice, DOE amends the 

cooking products test procedure to add 

provisions for measuring the combined 

low-power energy use, which will 

account for all energy use outside of the 

active cooking cycle 13 and fan-only 

mode. 

AHAM and Whirlpool disagree with 

DOE’s proposal to classify cycle 

finished mode for conventional cooking 

products as a standby mode. According 

to Whirlpool, any function begun by the 

user when initiating the active mode 

includes all power consumed until the 

full conclusion of that operation. 

Whirlpool believes that establishing a 

separate cycle finished mode adds 

complications and cost to the 

conventional cooking products test 

procedure without any corresponding 

improvement in energy consumption or 

value to the consumer. (AHAM, No. 14 

at p. 5; AHAM, NOPR Public Meeting 

Transcript, No. 10 at pp. 46–47; 

Whirlpool, No. 12 at pp. 2–3) NEEA 

stated that operation of the cooling fan 

that protects the electronic controls 

comprises cycle finished mode, with its 

duration being directly related to the 

temperature at which the active cooking 

function was conducted. According to 

NEEA, DOE should define cycle 

finished mode as the portion of the 

active mode between the end of the 

active cooking mode and the beginning 

of the inactive mode, when the cooling 

fan stops. (NEEA, No. 11 at pp. 2–4) 

As with dishwashers, DOE’s 

proposals narrowly defined cycle 

finished mode for conventional cooking 

products as providing continuous status 

display following operation in active 

mode. Because the function specified in 

this definition is a status display that 

may persist for an indefinite time until 

the user takes action, cycle finished 

mode for conventional cooking products 

would be classified as a standby mode 

under the general definition of ‘‘standby 

mode’’ adopted in today’s final rule for 

the conventional cooking products test 

procedure. DOE has also determined 

that any period of fan operation after the 

end of the active cooking cycle would 

be classified as a ‘‘fan-only mode’’ that 

is part of active mode. As discussed in 

section III.F.2 of today’s final rule, DOE 

includes in its amendments to the 

cooking products test procedure 

provisions to measure the energy use in 

fan-only mode if the conventional 

cooking product is capable of such 

operation. In today’s final rule, DOE 

also adds definitions of cycle finished 

mode and fan-only mode to the cooking 

products test procedure. 

3. Network Mode 

Section 3.7 of IEC Standard 62301 

(FDIS) 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 acknowledged in the December 

2010 NOPR 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 the time of the December 2010 

NOPR, however, DOE was 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. As a result, DOE 

could not evaluate networked units, 

even in terms of categorizing network 

mode as a standby mode or off mode 

function. In particular, DOE was 

unaware of methods for appropriately 

configuring networks or methods for 

collecting data about the energy use of 

appropriately configured networks. DOE 

also had no information as to whether 

network connection speed or the 

number and type of network 

connections affect power consumption 

for these products. DOE also had no 

information as to whether wireless 

network devices in such products 

would have different levels of power 

consumption when a device is 

establishing a connection versus when 

the network connection is established. 

DOE stated in the December 2010 NOPR 

that it was 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 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 the December 

2010 NOPR did not include provisions 

for testing network mode energy 

consumption in dishwashers, 

dehumidifiers, and conventional 

cooking products. DOE noted that 

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. 75 FR 

75290, 75299 (Dec. 2, 2010). 

AHAM and Whirlpool agreed with 

DOE that there are no dishwashers, 

dehumidifiers, or conventional cooking 

products on the market currently that 

are capable of operation in network 

mode, and that there is no way for DOE 

to gather data on this mode. Thus, these 

commenters agreed with DOE’s proposal 

not to address network mode until such 

time that sufficient data are available. 

AHAM and Whirlpool also stated that 

network mode would be distinct from 

standby or off mode. (AHAM, No. 14 at 

p. 6; AHAM, NOPR Public Meeting 

Transcript, No. 10 at pp. 48, 50; 

Whirlpool, No. 12 at p. 4) 

The NOPR/SNOPR2 Joint Comment, 

the California Utilities, ASAP, NEEA, 

and PG&E urged DOE to develop test 

methodology for network mode. 

According to these commenters, a 

number of major manufacturers are 

developing network-enabled 


srobinson on DSK4SPTVN1PROD with 
65954 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

dishwashers and cooking products, and 

these products are expected to be 

available on the market when the 

amended test procedures become 

effective. Further, these commenters 

stated that products with network 

capability may consume significant 

energy in network mode. ASAP and the 

NOPR/SNOPR2 Joint Comment stated 

that the energy use in network mode 

should be captured regardless of 

whether the product is actually 

connected to a network. NEEA noted 

that IEC Standard 62301 defines 

network mode as part of inactive mode, 

and that DOE should adopt a definition 

of network mode consistent with the 

one in IEC Standard 62301, along with 

methodology to measure network mode 

energy use during inactive mode testing. 

The SNOPR Joint Comment stated that 

the definition of standby mode is 

sufficiently broad to encompass energy 

use in network mode. (ASAP, NOPR 

Public Meeting Transcript, No. 10 at pp. 

49–50; California Utilities, No. 16 at p. 

3; NOPR/SNOPR2 Joint Comment, No. 

13 at pp. 3–4; SNOPR Joint Comment, 

No. 22 at p. 1; NEEA, No. 11 at pp. 4– 

5; PG&E, No. 17 at p. 3) 

In response to these comments, DOE 

observes that it is still not aware of any 

network-equipped dishwashers, 

dehumidifiers, and conventional 

cooking products that could allow 

sufficient analysis on which to 

categorize the functionality of network 

mode in these products, nor did 

commenters provide information or data 

on which to develop test methodology 

for measuring energy use in a network 

mode. Therefore, for the same reasons 

that DOE did not address network mode 

in the December 2010 NOPR, DOE is not 

adopting a definition or testing 

methodology for network mode in the 

dishwasher, dehumidifier, or 

conventional cooking products test 

procedures in today’s final rule. DOE 

reiterates, however, that it may consider 

amending these test procedures in a 

separate rulemaking in the future 

should network-equipped products and 

data on their functionality become 

available. 

4. Disconnected Mode 

DOE also noted in the December 2010 

NOPR 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 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 stated in 

the December 2010 NOPR that there 

would be no energy use in a 

disconnected mode and agreed that it 

would not be part of off mode, standby 

mode, or network mode. Therefore, DOE 

did not propose a definition or testing 

method for disconnected mode in the 

test procedures for residential 

dishwashers, dehumidifiers, or 

conventional cooking products. 75 FR 

75290, 75299–300 (Dec. 2, 2010). 

AHAM agreed that there would be no 

energy use in disconnected mode, and 

supported DOE’s decision not to amend 

the test procedures accordingly. 

(AHAM, No. 14 at p. 4) In consideration 

of this support and for the reasons 

discussed above, DOE does not amend 

the dishwasher, dehumidifier, and 

conventional cooking products test 

procedures to define or add testing 

provisions for disconnected mode in 

today’s final rule. 

E. Specifications for the Test Methods 

and Measurements for Standby Mode 

and Off Mode Testing 

As discussed in section III.C of this 

notice, DOE proposed in the December 

2010 NOPR to specify testing equipment 

and conditions for measuring standby 

mode and off mode energy use in the 

dishwasher, dehumidifier, and 

conventional cooking products test 

procedures, based on provisions in IEC 

Standard 62301 (First Edition). 75 FR 

75290, 75300–04 (Dec. 2, 2010). In 

September 2011 SNOPR, it proposed to 

incorporate by reference in the 

dishwasher, dehumidifier, and 

conventional cooking products test 

procedures the following provisions 

from IEC Standard 62301 (Second 

Edition) for testing equipment and 

conditions: (1) The room ambient air 

temperature requirements in section 4, 

paragraph 4.2; (2) the electrical supply 

voltage requirements in section 4, 

paragraph 4.3.2; (3) the power 

equipment specifications in section 4, 

paragraph 4.4; (4) the instructions for 

allowing the product to enter a lower 

power state prior to the test 

measurement in section 5, paragraph 

5.1, note 1; and (5) portions of the 

installation and setup procedures in 

section 5, paragraph 5.2. 76 FR 58436, 

58349–54 (Sep. 20, 2011). 

1. Ambient Conditions, Including for 

Active Mode 

In the December 2010 NOPR, DOE 

proposed that test room ambient 

temperatures for standby mode and off 

mode testing be specified for all 

dishwashers, dehumidifiers, and 

conventional cooking products 

according to section 4, paragraph 4.2 of 

IEC Standard 62301 (First Edition). 75 

FR 75290, 75301–02 (Dec. 2, 2010). The 

First Edition specified a temperature 

range of 73.4 ± 9 °F. Section 4, 

paragraph 4.2 of IEC Standard 62301 

(Second Edition) contains an identical 

requirement for the test room ambient 

temperature, which DOE proposed to 

reference for standby mode and off 

mode testing in the September 2011 

SNOPR. In the December 2010 NOPR, 

DOE also compared the IEC Standard 

62301 (First Edition) ambient 

temperature ranges to those specified in 

the current DOE dishwasher, 

dehumidifier, and conventional cooking 

products test procedures for active 

mode testing as follows. Because the 

same IEC ambient temperatures were 

specified in the Second Edition, DOE 

drew the same tentative conclusions in 

the September 2011 SNOPR. 

DOE noted in the December 2010 

NOPR that the current DOE test 

procedure for dishwashers includes a 

test room ambient air temperature 

requirement of 75 ± 5 °F, which helps 

ensure consistent and repeatable test 

results for active mode measurements in 

which heat losses could affect energy 

consumption. Because energy use in 

standby mode or off mode is less 

affected by ambient temperature than 

active mode energy use, DOE proposed 

to allow manufacturers of dishwashers 

to use the less stringent ambient 

temperature range in IEC Standard 

62301 (First Edition) for standby mode 

and off mode power consumption 

measurement. DOE further stated that 

manufacturers could choose to use the 

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. 75 FR 75290, 

75301 (Dec. 2, 2010). 

For dehumidifiers, the current DOE 

test procedure specifies a test room 

ambient temperature of 80 ± 2 °F. As 

with dishwashers, DOE’s proposal in 

the December 2010 NOPR 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 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65955 

temperature requirement of 73.4 ± 9 °F. 

75 FR 75290, 75301 (Dec. 2, 2010). 

The current DOE test procedure for 

conventional cooking products includes 

a test room ambient air temperature 

specification of 77 ± 9 °F, which varies 

slightly from the range specified by IEC 

Standard 62301 of 73.4 ± 9 °F. DOE 

stated in the December 2010 NOPR that 

the higher temperatures allowed for 

active mode energy testing could be 

representative of ambient temperatures 

during a cooking process, but that 

maintaining lower allowable 

temperatures for standby mode and off 

mode power consumption 

measurements would 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 proposal would allow 

a manufacturer to conduct standby 

mode and off mode testing separately 

from performance testing within an 

ambient temperature range of 73.4 ± 9 

°F. 75 FR 75290, 75301–02 (Dec. 2, 

2010). 

AHAM stated that DOE should use 

the ambient temperature requirements 

in its current dishwasher, dehumidifier, 

and conventional cooking products test 

procedures for standby mode and off 

mode energy use measurements, which 

AHAM stated would produce accurate, 

repeatable, and reproducible results. 

AHAM and Whirlpool noted that the 

DOE temperature requirements are more 

stringent for dishwashers and 

dehumidifiers, and that DOE’s ambient 

temperature requirements in the 

cooking products test procedure 

substantially overlaps with the IEC 

temperature range. For the same reasons 

as AHAM outlined, BSH commented 

that the more stringent DOE ambient 

temperature requirements in the 

dishwasher test procedure should apply 

for standby mode and off mode testing. 

(AHAM, No. 14 at pp. 7–8; AHAM, No. 

27 at p. 12; AHAM, NOPR Public 

Meeting Transcript, No. 10 at p. 63; 

BSH, No. 28 at pp. 9–10; Whirlpool, No. 

26 at p. 1) AHAM, BSH, and Whirlpool 

suggested a single temperature range 

would reduce inadvertent testing error. 

Whirlpool recommended more stringent 

ambient room temperatures for the 

dishwasher and conventional cooking 

products test procedures for all testing— 

75 ± 2 °F for dishwashers and 75 ± 5 °F 

for conventional cooking products—and 

supported conducting all dehumidifier 

testing under the current DOE active 

mode test conditions of 80 ± 2 °F. 

According to Whirlpool, a 1 °F 

difference in ambient temperature can 

cause a 1.5 kWh change in the 

measurement of dishwasher annual 

energy use. AHAM stated that not every 

laboratory could achieve a tolerance 

tighter than ± 5 °F for dishwasher 

testing. (AHAM, No. 14 at pp. 7–8; 

AHAM, No. 27 at p. 12; AHAM, 2012 

Public Meeting Transcript, No. 38 at pp. 

152–153; BSH, No. 28 at pp. 9–10; 

Whirlpool, No. 12 at pp. 4–5; Whirlpool, 

No. 21 at p. 3; Whirlpool, No. 26 at pp. 

1, 5) AHAM, BSH, and Whirlpool also 

stated that the dishwasher test 

procedure should clarify that the 

tolerances specified indicate the 

allowable limits of variation in 

temperature, but do not permit the 

deliberate variation with those limits. 

(AHAM, No. 27 at p. 12; AHAM, 2012 

Public Meeting Transcript, No. 38 at p. 

151; BSH, No. 28 at p. 10; Whirlpool, 

No. 26 at p. 1; Whirlpool, 2012 Public 

Meeting Transcript, No. 38 at pp. 153– 

154) Intertek noted that it understood 

that the intent of the dishwasher test 

procedure is to target 75 °F, and they 

aim to maintain this ambient 

temperature. According to Intertek, it is 

also important to maintain this 

temperature prior to conducting the test 

when the soils are drying on the test 

load. (Intertek, 2012 Public Meeting 

Transcript, No. 38 at pp. 154–155) 

In the August 2012 SNOPR, DOE 

maintained its proposals that the 

standby mode and off mode testing for 

dishwashers, dehumidifiers, and 

conventional cooking products be 

allowed to be conducted under either 

the ambient temperature range specified 

in IEC Standard 62301 (Second Edition) 

or the ambient temperature range 

specified in the DOE test procedure 

where the DOE active mode temperature 

range overlaps the IEC temperature 

range. DOE re-examined this issue in 

light of the comments received. DOE 

confirmed its proposed approach to not 

require that standby mode and off mode 

testing be conducted under the same 

ambient temperature as active mode 

testing because no data were available to 

suggest that the standby mode and off 

mode power of residential dishwashers 

varies significantly within the allowable 

ambient temperature range of IEC 

Standard 62301 (Second Edition), and 

because this approach would increase 

the burden for those manufacturers or 

laboratories that choose to conduct 

standby mode and off mode testing 

separately from active mode testing. 77 

FR 49064, 49066 (Aug. 15, 2012) 

In the August 2012 SNOPR, DOE also 

responded to comments on the intent of 

the ambient temperature range in the 

dishwasher test procedure by noting 

that the tolerances specified in the DOE 

test procedures provide a range of 

temperatures under which the test 

results are considered valid, regardless 

of the reasons for why a particular 

temperature within the range was 

selected or achieved. Therefore, DOE 

did not alter its proposal to state that the 

dishwasher test should be conducted at 

the nominal center of the ambient 

temperature range. DOE stated that it 

recognized the impact of ambient 

temperature on the active mode 

measurement, however, and as an 

alternative to the ±5 °F tolerance in the 

current test procedure for active mode 

testing, DOE proposed to tighten the 

tolerance on the test room ambient 

temperature in the dishwasher test 

procedure to ±2 °F for active mode 

testing. Id. 

DOE did not receive comments in 

response to the August 2012 SNOPR on 

the proposal that the standby mode and 

off mode testing for dishwashers, 

dehumidifiers, and conventional 

cooking products may be conducted 

within the range of ambient 

temperatures where the specified 

temperature ranges of IEC Standard 

62301 (Second Edition) and the DOE 

test procedure overlap if the testing 

laboratory chooses to conduct standby 

mode and off mode testing in the same 

facility as for active mode testing. DOE 

acknowledges the previous comments 

which identify the potential for 

inadvertent testing error if the standby 

mode and off mode testing is conducted 

under different ambient temperatures 

than active mode testing, but 

determined that the potential for such 

error is outweighed by the flexibility 

provided to manufacturers and testing 

laboratories to conduct standby mode 

and off mode testing separately from 

active mode testing. In addition, 

commenters did not provide 

information that would suggest that the 

more stringent ambient temperature 

requirements currently specified in the 

DOE dishwasher, dehumidifier, and 

conventional cooking product test 

procedures would reduce variability in 

the standby mode and off mode energy 

use measurement. For these reasons, 

today’s final rule incorporates by 

reference in the new dishwasher and 

dehumidifier test procedures and 

amended conventional cooking 

products test procedure the ambient 

temperature requirements specified in 

section 4 of IEC Standard 62301 (Second 


srobinson on DSK4SPTVN1PROD with 
65956 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

Edition) for measuring standby mode 

and off mode power consumption. 

In response to the August 2012 

SNOPR, AHAM, BSH, Samsung, and 

Whirlpool continued to suggest that the 

dishwasher active mode test should be 

conducted at the nominal center of the 

ambient temperature range, but 

acknowledged that a tighter tolerance 

would also help minimize test-to-test 

variation. Whirlpool supported the 

proposal to tighten the tolerance to ±2 

°F, and stated that any additional 

burden associated with this requirement 

is small. Whirlpool commented that it 

will be able to meet the proposed tighter 

ambient temperature tolerance. None of 

the commenters provided information 

on whether all laboratories are capable 

of achieving a ±2 °F temperature range, 

but AHAM, BSH, and Samsung believe 

that some laboratories would need to 

make significant investments to meet 

this requirement. BSH added that at 

certain times of the year its laboratories 

would not be able to meet the 75 ±2 °F 

temperature range, requiring costly 

modifications to achieve consistent 

performance. BSH noted that it also 

conducts dishwasher testing according 

to the IEC dishwasher test procedure 

that requires an ambient temperature 

range of 64.4 to 71.6 °F. The current 

DOE active mode temperature 

specification provides an overlap 

between the lower end of the DOE 

temperature range and the upper end of 

the IEC range, allowing BSH to conduct 

both tests in the same laboratory at the 

same time. DOE’s proposal for 75 ±2 °F 

would not allow this overlap, and could 

potentially require BSH to have separate 

laboratories for DOE and IEC testing. 

(AHAM, No. 35 at p. 7; BSH, No. 36 at 

p. 3; Samsung, No. 33 at p. 1; Whirlpool, 

No. 32 at p. 1; Whirlpool, No. 34 at p. 

2) 

DOE carefully considered these 

comments and whether the potential 

improvement in the test procedure 

results by requiring a tighter ambient 

temperature tolerance for dishwasher 

active mode testing would warrant the 

significant costs that could potentially 

be incurred by at least some test 

laboratories and manufacturers. 

Although it does not have information 

on the number of affected laboratories, 

DOE observes that at least one 

manufacturer would need to upgrade its 

facilities, and would incur additional 

cost by not being able to conduct all its 

active mode testing, i.e., testing both for 

demonstrating compliance with DOE 

energy conservation standards and for 

evaluating consumer utility associated 

with cleaning performance, in a single 

laboratory. Although test repeatability 

and reproducibility would be improved 

by specifying a more stringent ambient 

temperature tolerance, DOE determined 

that the significant potential costs do 

not warrant the benefits of such a 

specification. As a result, DOE is not 

changing the required range in ambient 

temperatures for active mode testing in 

the dishwasher test procedure. In 

addition, for the reasons stated in the 

August 2012 SNOPR, DOE is not 

amending the dishwasher test procedure 

to require that the active mode test be 

conducted at the nominal center of the 

ambient temperature range. 

AHAM and GE stated that the test 

room humidity should be specified for 

dehumidifier standby mode and off 

mode testing to prevent the unit from 

inadvertently cycling on. (AHAM, No. 

14 at p. 7; GE, NOPR Public Meeting 

Transcript, No. 10 at p. 64) Neither 

commenter provided information on an 

appropriate ambient humidity level for 

this testing, and no such requirement is 

contained within IEC Standard 62301 

(Second Edition). Therefore, DOE is not 

adopting an ambient humidity 

requirement in today’s final rule for 

standby mode and off mode testing in 

the new dehumidifier test procedure. 

DOE does, however, clarify in section 

4.2 of appendix X1 that standby mode 

and off mode testing should be 

conducted while ensuring that the 

dehumidifier does not enter active mode 

during the test. 

2. Installation and Power Supply 

Requirements 

AHAM and Whirlpool supported the 

requirement to conduct standby mode 

and off mode testing at the factory or 

default setting, or where there are no 

indications of those settings, in the asshipped condition, in accordance with 

section 5.2 of IEC Standard 62301 

(Second Edition). According to these 

commenters, this requirement would 

provide clarity, ensure repeatability, 

and reduce testing burden. (AHAM, No. 

14 at pp. 3–4, 6; Whirlpool, No. 12 at 

pp. 2, 4; Whirlpool, NOPR Public 

Meeting Transcript, No. 10 at p. 58) 

AHAM also stated that it supports the 

power supply requirements proposed to 

be referenced from IEC Standard 62301 

(Second Edition). (AHAM, No. 14 at pp. 

7–8) DOE adopts in today’s new 

dishwasher and dehumidifier test 

procedures and amended conventional 

cooking products test procedure 

references to the electrical supply 

voltage requirements in section 4, 

paragraph 4.3.2 and portions of the 

installation and setup procedures in 

section 5, paragraph 5.2 of IEC Standard 

62301 (Second Edition). 

3. Standby Mode and Off Mode Testing 

Methodology 

In the December 2010 NOPR, DOE 

also proposed for all covered products 

to require measurement of standby 

mode and off mode power using section 

5, paragraph 5.3 of IEC Standard 62301 

(First Edition), clarified by requiring the 

product to stabilize for at least 30 

minutes and using an energy use 

measurement period of not less than 10 

minutes. Further, for any dishwasher or 

dehumidifier in which the power varies 

over a cycle, as described in section 5, 

paragraph 5.3.2 of IEC Standard 62301 

(First Edition), the December 2010 

NOPR proposed to require the use of the 

average power approach in section 5, 

paragraph 5.3.2(a), with the same 30- 

minute minimum stabilization and 10- 

minute minimum measurement periods, 

as long as the measurement period 

comprises one or more complete cycles. 

75 FR 75290, 75300–01 (Dec. 2, 2010) 

DOE additionally proposed specific 

methodology for conventional cooking 

products in which power varies as a 

function of the time displayed. In that 

case, testers would be allowed to choose 

measuring standby power by means of 

either the 10-minute test or the 12-hour 

test, as described in section III.C of 

today’s notice. According to the 

proposal, manufacturers could elect to 

conduct either a 10-minute test or a 12- 

hour test, or both, and results of the 10- 

minute test that are within ±2 percent of 

the results for the 12-hour test would be 

deemed to be representative of average 

energy use. Id. at 75302–04, 75328. 

In the September 2011 SNOPR, DOE 

updated its proposal to reference testing 

methodology from IEC Standard 62301 

(Second Edition). DOE tentatively 

concluded that the application of the 

provisions of the Second Edition to all 

power measurements in standby mode 

and off mode for dishwashers and 

dehumidifiers would be appropriate, 

and proposed incorporation by 

reference of the relevant paragraphs of 

section 5.3 of IEC Standard 62301 

(Second Edition) in the test procedures 

for these products. Further, DOE noted 

in the September 2011 SNOPR that 

although the Second Edition allows the 

choice of multiple test methods for both 

stable and unstable non-cyclic power 

consumption, the IEC preferred 

sampling method provides for a test 

duration that is approximately the same 

or shorter than the allowable IEC 

alternative methods and does not 

require classification of the nature of the 

power consumption (e.g., stable or 

unstable, non-cyclic) in advance of the 

test. By monitoring the variation in 

power consumption during the test, the 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65957 

test operator could determine whether it 

is stable or unstable, and, thus, the 

required duration of the sampling 

periods. For cyclic power consumption, 

the Second Edition requires the use of 

the sampling method. Thus, DOE 

proposed in the September 2011 SNOPR 

to specify the use of the sampling 

method in section 5.3.2 of IEC Standard 

62301 (Second Edition) for all measures 

of standby mode and off mode power 

consumption for residential 

dishwashers and dehumidifiers. 76 FR 

58346, 58351–53 (Sep. 20, 2011). 

DOE did not receive comments in 

response to the proposed standby mode 

and off mode power consumption 

measurement methods for dishwashers 

and dehumidifiers, and for the reasons 

discussed, adopts such amendments in 

the new dishwasher and dehumidifier 

test procedures in today’s final rule. 

For conventional cooking products, 

DOE tentatively concluded in the 

September 2011 SNOPR that section 5.3 

of IEC Standard 62301 (Second Edition) 

includes provisions that are appropriate 

for measuring off mode and standby 

modes, except in the case of a unit’s 

clock whose power consumption varies 

by the time displayed, and that the 

sampling method in section 5.3.2 of IEC 

Standard 62301 (Second Edition) would 

also provide for measurements with 

minimal test burden. Thus, DOE 

proposed in the September 2011 SNOPR 

for conventional cooking products to 

require the use of the sampling method 

in section 5.3.2 of IEC Standard 62301 

(Second Edition), except as follows. In 

the narrow case of cooking products 

with power consumption that varies as 

a function of the time displayed, DOE 

determined that the application of the 

test methodology from IEC Standard 

62301 (Second Edition) would cause 

manufacturers to incur significant 

burden that would not be warranted by 

any potential improved accuracy of the 

test measurement. For this reason, DOE 

continued to propose in the September 

2011 SNOPR the 10-minute and 12-hour 

test methods for these products in the 

conventional cooking products test 

procedure, based upon the average 

power method from IEC Standard 62301 

(First Edition). The September 2011 

SNOPR also proposed to amend the 

reference in 10 CFR 430.3 to add a 

reference to IEC Standard 62301 

(Second Edition). DOE’s proposal for 

conventional cooking products, based 

on relevant sections of IEC Standard 

62301 (Second Edition) would neither 

be affected by, nor impact, the testing 

procedures for microwave ovens other 

than section renumbering as 

appropriate. 76 FR 58346, 58351–53. 

(Sep. 20, 2011). 

AHAM and Whirlpool supported the 

10-minute testing methodology for 

conventional cooking products with 

power consumption that varies as a 

function of the time displayed, but 

stated that the time that a product takes 

to return to the lowest power 

consumption state after setting the clock 

may vary and that this stabilization 

period may be shorter or longer than 10 

minutes. They commented that DOE 

should require the clock to be set to a 

time of 3:33 minus the number of 

minutes of the stabilization period. 

According to AHAM, each manufacturer 

will know the length of the stabilization 

period for its products. AHAM also 

suggested that DOE could require 

manufacturers to submit in their 

certification report to DOE the length of 

the stabilization period, which should 

not be made public since it is 

confidential business information. 

(AHAM, No. 14 at p. 8; AHAM, No. 20 

at pp. 2–3; AHAM, NOPR Public 

Meeting Transcript, No. 10 at pp. 73, 77; 

Whirlpool, No. 12 at p. 5; Whirlpool, 

No. 21 at p. 2) Whirlpool stated that the 

12-hour test would place significant 

burden on manufacturers, and that the 

10-minute test has been demonstrated to 

yield representative results. (Whirlpool, 

No. 21 at p. 2) 

ASAP commented that the proposed 

approach for allowing either a 10- 

minute or 12-hour test was a reasonable 

balance between manufacturer test 

burden and enforcement. (ASAP, NOPR 

Public Meeting Transcript, No. 10 at pp. 

76–77) AHAM and Whirlpool 

questioned whether a model that met an 

energy conservation standard when 

tested by the manufacturer using the 10- 

minute method but that did not meet 

the standard when tested by DOE using 

the 12-hour method would be deemed 

compliant if the results between the two 

tests were within the 2-percent 

variation. Whirlpool believes that the 

option of two test methods is 

unnecessary. (AHAM, No. 14 at p. 9; 

AHAM, No. 20 at p. 3; AHAM, NOPR 

Public Meeting Transcript, No. 10 at pp. 

73–75; Whirlpool, No. 12 at p. 5; 

Whirlpool, No. 21 at p. 2) 

Upon review of comments from 

interested parties, DOE concludes that a 

12-hour test requirement would 

represent a significant burden to 

manufacturers, and that the alternative 

10-minute method would minimize 

additional test burden. DOE agrees that 

the time required by certain products 

may be different than the 10-minute 

stabilization period provided in the 10- 

minute test method. DOE does not 

believe, however, that allowing the 

manufacturers to individually 

determine the stabilization period 

would optimize the accuracy and 

repeatability of the test procedure, 

particularly when the method is used at 

testing laboratories other than that of the 

manufacturer. Based on its testing, DOE 

determined that a requirement to set the 

display time to 3:23 and allowing a 10- 

minute stabilization period prior to a 

10-minute measurement period would 

best balance the need for reproducibility 

of the test procedure with the burden 

placed on manufacturers. Therefore, 

DOE adopts in today’s final rule the 

proposed standby mode and off mode 

testing methodology for conventional 

cooking products, but eliminating the 

12-hour testing option for conventional 

cooking products with power 

consumption that varies as a function of 

the time displayed. 

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 

amendments reflect 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. It has been the 


srobinson on DSK4SPTVN1PROD with 
65958 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

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. 

F. Calculation of Energy Use Associated 

With Operational Modes 

1. Standby Mode and Off Mode 

In the December 2010 NOPR, DOE 

proposed a methodology for measuring 

energy consumption in modes other 

than active washing mode for 

dishwashers and active cooking mode 

for conventional cooking products; i.e., 

inactive (standby) mode and off mode, 

as well as delay start mode and cycle 

finished mode. These modes are 

collectively referred to as low-power 

modes. DOE also raised the possibility 

of using a similar methodology for 

measuring low-power modes for 

dehumidifiers, including inactive 

(standby) mode, off mode, off-cycle 

mode, and bucket full/removed mode. 

DOE proposed in the December 2010 

NOPR to allocate specific annual hours 

to each of the active, standby, and off 

modes. Using this approach, the annual 

energy use associated with the lowpower modes would be calculated by: 

(1) Calculating the product of wattage 

and allocated hours for all possible lowpower modes; (2) summing the results; 

and (3) dividing the sum by 1,000 to 

convert from Wh to kWh. For each 

product, DOE estimated the hours 

allocated to each mode, and for those 

products with both electronic controls 

and a mechanical on/off switch, DOE 

proposed to evenly split the hours 

between inactive mode and off mode. 

For the per-cycle energy use metrics for 

dishwashers and conventional cooking 

products, this value would be divided 

by the proposed annual active use 

cycles per year. For dehumidifiers, 

which measure energy use over a 24- 

hour period, the annual energy use in 

the low-power mode would be divided 

by the active mode hours per year and 

multiplied by 24 hours. 75 FR 75290, 

75306, 75310–15 (Dec. 2, 2010). 

As an alternate approach for 

dishwashers and conventional cooking 

products, DOE also proposed measuring 

power consumption for only off and 

inactive modes for the purpose of 

calculating the total energy consumed in 

all low-power modes. Using this 

approach, energy use in delay start and 

cycle finished mode would be 

accounted for by allocating all the hours 

not associated with active washing or 

cooking mode to the inactive (standby) 

and off modes and then measuring 

standby or off mode power. For 

dehumidifiers, DOE considered the 

possibility of a similar alternative 

approach in which energy use in which 

all hours other than active 

dehumidification mode would be 

allocated to inactive mode, off-cycle 

mode, and off mode. DOE observed that 

dehumidifiers are generally capable of 

either off mode or inactive mode, 

depending on the type of controls, when 

the unit is plugged in but not turned on. 

Each type of dehumidifier would 

operate in off-cycle mode when the unit 

is powered on and the relative humidity 

level in the room is below the 

dehumidifier humidity set point. 75 FR 

75290, 75306, 76308, 75310–13 (Dec. 2, 

2010). DOE retained these proposals in 

the September 2011 SNOPR and 

received comments in support of the 

alternate approach. As a result, DOE 

proposed the alternate approach for 

dishwashers and conventional cooking 

products in the May 2012 SNOPR. 77 

FR 31444, 31451 (May 25, 2012). 

AHAM, BSH, the California Utilities, 

PG&E, and Whirlpool opposed the 

allocation of annual hours to different 

modes proposed for the dishwasher, 

dehumidifier, and conventional cooking 

products test procedures, commenting 

that DOE did not base the proposals on 

sufficient U.S. consumer use data. 

AHAM, BSH, and Whirlpool further 

commented that if DOE moves forward 

with its proposal, the alternative 

approach is preferable. (AHAM, No. 14 

at pp. 9–14; AHAM, No. 27 at p. 13; 

AHAM, NOPR Public Meeting 

Transcript, No. 10 at pp. 85, 97–98, 109; 

BSH, No. 28 at p. 11; California Utilities, 

No. 16 at p. 3; PG&E, No. 17 at p. 3; 

Whirlpool, No. 12 at p. 6; Whirlpool, 

No. 26 at pp. 1, 3) The California 

Utilities and PG&E commented that 

delay start mode should be measured as 

part of active mode, but supported 

including delay start energy use in 

standby mode energy use as a temporary 

measure. ASAP, the California Utilities, 

and PG&E questioned DOE’s estimates 

of the annual hours spent in cycle 

finished mode, while GE stated that 

DOE’s estimates for dehumidifier bucket 

full/removed mode are too high. (ASAP, 

NOPR Public Meeting Transcript, No. 10 

at pp. 109–110; California Utilities, No. 

16 at pp. 2, 4; PG&E, No. 17 at pp. 2,4; 

Whirlpool, NOPR Public Meeting 

Transcript, No. 10 at pp. 94–95) 

ASAP, the California Utilities, the 

NOPR/SNOPR2 Joint Comment, and 

PG&E stated that DOE should specify 

the placement of the mechanical on/off 

switch so that consumers would turn 

the product off, thereby justifying the 

proposed split between inactive mode 

and off mode hours. AHAM (ASAP, 

NOPR Public Meeting Transcript, No. 10 

at pp. 87, 109; California Utilities, No. 

16 at p. 4; NOPR/SNOPR2 Joint 

Comment, No. 13 at p. 6; PG&E, No. 17 

at p. 4) AHAM commented that DOE 

should require that mechanical on/off 

switch be accessible to the consumer, 

but should not specify product design. 

(AHAM, No. 14 at p. 12) 

In today’s final rule, DOE maintains 

its determination from the May 2012 

SNOPR for both dishwashers and 

conventional cooking products, and, as 

contemplated in the December 2010 

NOPR, makes a similar determination 

for dehumidifiers, that the power 

consumption in each of the low-power 

modes is similar, and that in such a 

case, measuring power consumption of 

each mode separately would introduce 

significant test burden without a 

corresponding improvement in a 

representative measure of annual energy 

use. In consideration of support from 

interested parties for the alternate 

calculation method and the lack of 

additional consumer use data that 

would improve the original proposal, 

DOE establishes in the new dishwasher 

and amended conventional cooking 

products test procedures provisions to 

account for standby mode and off mode 

energy use by measuring inactive mode 

and off mode power consumption only, 

and allocating that power consumption 

to all hours spent in the low-power 

modes combined. 

The same alternative calculation of 

combined low-power mode energy use 

is adopted in today’s final rule in the 

new dehumidifier test procedure. The 

provisions require that dehumidifiers 

with off mode capability (i.e., those 

units with electronic controls that may 

be shut off with a mechanical switch or 

with mechanical controls) shall be 

measured in off mode and off-cycle 

mode. For dehumidifiers not capable of 

operation in off mode (i.e., units with 

electronic controls that may not be shut 

off with a mechanical switch), inactive 

mode and off-cycle mode shall be 

measured. The annual hours for all lowpower modes combined shall be split 

evenly between off-cycle mode and 

either inactive mode and off mode, 

depending on the unit’s capability. 

Although DOE did not previously 

propose this specific alternative 

methodology for dehumidifiers, it 

suggested that such an approach could 

be adopted in the final rule. DOE is 

adopting this approach today after 

noting the preponderance of supporting 

comments for the alternative approach, 

and weighing carefully the benefits of 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65959 

reduced testing burden of this approach 

against the minor improvements in 

accuracy of the standby mode and off 

mode energy use obtained by measuring 

each low-power mode separately. 

2. Fan-Only Mode 

In the May 2012 SNOPR, DOE 

proposed to define fan-only mode in the 

test procedures for dishwashers and 

conventional cooking products as an 

active mode in which a fan circulates air 

for a finite period of time after the end 

of the dishwasher cycle or conventional 

cooking product heating function, as 

indicated to the consumer. DOE also 

proposed provisions to measure energy 

use in fan-only mode, in which the 

power consumption and duration of fanonly mode would be measured at the 

end of each active mode cycle required 

by the test procedure, and the resulting 

energy consumption would be included 

in the energy efficiency metrics for that 

product. 77 FR 31444, 31451 (May 25, 

2012). 

In response to the May 2012 SNOPR, 

the NOPR/SNOPR2 Joint Comment 

stated that it supports incorporating 

measurement of fan-only mode energy 

use in the dishwasher and conventional 

cooking products test procedures, as 

this would provide an incentive to 

manufacturers to reduce fan-only mode 

energy consumption. (NOPR/SNOPR2 

Joint Comment, No. 29 at p. 1) AHAM, 

BSH, and Whirlpool stated they would 

not oppose the measurement of fan-only 

mode energy use for dishwashers or 

conventional cooking products, as long 

as fan-only mode is not a user-selectable 

option. Whirlpool commented that 

classifying fan-only mode as part of 

active mode would be consistent with a 

determination that active mode persists 

until the end of the operating cycle. 

However, AHAM, BSH, and Whirlpool 

stated that measuring energy 

consumption in this mode according to 

the proposed method would represent a 

significant burden due to the increased 

length of each test. AHAM, BSH, and 

Whirlpool recommended that DOE 

allow as an option a one-time 

measurement or sampling approach to 

measure fan-only mode energy use over 

a brief time period combined with a 

calculation to properly account for its 

contribution to annual energy use in the 

test procedures for dishwashers and 

conventional cooking products. (AHAM, 

No. 27 at pp. 2–3; BSH, No. 28 at p. 2; 

Whirlpool, No. 26 at pp. 1–2) 

Whirlpool further commented that 

DOE’s estimate that a dishwasher fan 

could run for 4 hours after each cycle, 

consuming 17 kWh per year or 4.7 

percent of the current maximum energy 

consumption, was incorrect. Whirlpool 

stated that fan operation is a function of 

the residual heat remaining in the unit 

after completion of the wash cycle and 

the degree of drying selected, and thus, 

the fan will not operate for this length 

of time on every cycle. Whirlpool 

similarly commented that DOE’s 

estimate that a conventional cooking 

product fan could run for 3.5 hours after 

each cycle, consuming as much as 38 

kWh per year, was incorrect because fan 

operation is a function of the residual 

heat remaining in the unit after 

completion of the cooking cycle and of 

the ambient temperature. (Whirlpool, 

No. 26 at p. 2) 

As part of the calculation in the May 

2012 SNOPR, DOE provided a range of 

the annual impacts of fan-only energy 

consumption in residential dishwashers 

and conventional cooking products. 

While DOE agrees that most 

dishwashers and conventional cooking 

products will not operate in fan-only 

mode for 4 hours or 3.5 hours, 

respectively, DOE is aware of products 

capable of these durations, and therefore 

concludes that the values in the May 

2012 SNOPR are appropriate estimates 

of the maximum amount of energy 

consumed in this mode. However, the 

proposal for dishwasher and 

conventional cooking product test 

methods for measuring energy use in 

fan-only mode in the May 2012 SNOPR 

would be based on the actual length of 

fan-only mode for the product under 

test. 

For the August 2012 SNOPR, DOE 

continued to propose the methodology 

first proposed in the May 2012 SNOPR, 

and also provided an alternative 

methodology to reduce test burden in 

which, if fan-only mode is not a userselectable option, the power 

consumption would be measured for a 

brief time period, such as 10 minutes, 

and then extrapolated over the length of 

the entire fan-only mode cycle. DOE 

sought representative data on the length 

of the fan-only mode cycle for 

dishwashers and conventional cooking 

products. 77 FR 49064, 49067 (Aug. 15, 

2012). 

AHAM, BSH, Samsung, and 

Whirlpool support the alternative 

approach under which the energy use of 

fan-only mode would be measured only 

if is not a user-selectable option, 

although they noted this approach could 

produce non-representative results if the 

energy use during fan-only mode is not 

constant. These commenters cited an 

example in which the fan could stop 

and start over the course of the fan-only 

mode, or it could operate at a different 

wattage at times other than during the 

sampling period. Therefore, AHAM, 

BSH, Samsung, and Whirlpool suggest 

that DOE include language to require 

that the measured time period of 10 

minutes be representative of average 

energy usage. If the measurement period 

is not representative, the full fan-only 

mode should be measured. (AHAM, No. 

35 at pp. 9–10; BSH, No. 36 at p. 3; 

Samsung, No. 33 at p. 1; Whirlpool, No. 

32 at p. 1) ASAP, NCLC, and NRDC, 

jointly (hereafter the ‘‘SNOPR3 Joint 

Comment’’) support measuring fan-only 

mode energy use for the duration of fanonly mode, as originally proposed in the 

May 2012 SNOPR. These commenters 

stated they are not aware of available 

data on the representative cycle times of 

fan-only mode for dishwashers or 

conventional cooking products, and that 

given the wide variations in fan-only 

cycle times observed in the products, 

any assumed cycle time would result in 

significantly over-estimating or underestimating the actual energy 

consumption in fan-only mode for a 

majority of products. (SNOPR3 Joint 

Comment, No. 37 at pp. 1–2) 

Measuring fan-only mode energy use 

over the full duration of fan-only mode 

may provide slightly more accuracy in 

the results, but such an approach can 

represent significant testing burden in 

the event that the duration of fan-only 

mode extends to several hours. 

Additionally, DOE agrees with the 

SNOPR3 Joint Comment that any single 

value for a representative duration of 

fan-only mode for a dishwasher or 

conventional cooking product that DOE 

may prescribe in its test procedures 

would likely not result in representative 

energy use for a number of such 

products. To use the alternate method 

and extrapolate the results over the 

duration of fan-only mode, 

manufacturers must know and use the 

length of the fan-only mode operation. 

Use of the alternative approach would 

substantially reduce testing burden 

while resulting in representative energy 

use for this mode. Therefore, in today’s 

final rule, DOE adopts provisions in the 

new dishwasher test procedure and 

amends the current conventional 

cooking products test procedure to 

include the methodology proposed in 

the May 2012 SNOPR for measuring 

energy use over the full duration of fanonly mode, but also allow the choice of 

the alternative method, using a testing 

duration of 10 minutes, where the 

duration of fan-only mode is known and 

the resulting energy use extrapolated 

over the entire fan-only mode will be 

representative. For conventional 

cooking products, DOE’s proposed 

amendments for measuring fan-only 

mode energy use are corrected in 

today’s final rule so that the energy use 


srobinson on DSK4SPTVN1PROD with 
65960 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

is determined in kilowatt-hours rather 

than hours. 

AHAM and Whirlpool also 

commented that DOE should clarify 

what ‘‘as indicated to the consumer’’ 

means in the fan-only mode definition. 

According to AHAM, this could refer to 

the end of the heating function for a 

cooking product or dishwasher cycle, or 

when the consumer is notified of the 

end of the heating function or 

dishwasher cycle and the fan is running, 

or something else. (AHAM, No. 27 at p. 

2; Whirlpool, No. 26 at p. 1) In today’s 

final rule, DOE provides further 

clarification in the definition of fan-only 

mode that indication to the consumer of 

the end of the cycle is by means of a 

display, indicator light, or audible 

signal. 

3. Dishwasher Water Softener 

Regeneration 

In the May 2012 SNOPR, DOE 

proposed a method for measuring the 

energy consumed during regeneration 

cycles for water softeners built into 

certain residential dishwashers. The 

proposed test procedure would measure 

the machine electrical energy 

consumption and the water 

consumption of a water softener 

regeneration cycle. DOE considered 

information submitted by manufacturers 

in petitions for waiver from the DOE test 

procedure to determine an appropriate 

method for incorporating water softener 

regeneration energy and water 

consumption into the overall metrics. 77 

FR 31444, 31449–52 (May 25, 2012). 

The NOPR/SNOPR2 Joint Comment 

supported the proposed water softener 

regeneration test procedure, and noted 

that the test procedure would eliminate 

the need for additional test procedure 

waivers. (NOPR/SNOPR2 Joint 

Comment, No. 29 at p. 1) AHAM, BSH, 

and Whirlpool opposed the proposed 

test method because it would be 

burdensome and result in only a small 

amount of additional measured energy 

and water consumption. Whirlpool 

commented that it submitted detailed 

data on the frequency, energy use, and 

water use of water softeners in its 

petition for wavier, and in granting the 

waiver, DOE agreed to add constant 

values of 4 kWh and 23 gallons per year 

to the results calculated under the test 

procedure. According to Whirlpool, 

these represent a very modest amount of 

annual energy and water consumption. 

(AHAM, No. 27 at pp. 3–4; BSH, No. 28 

at p. 2; BSH, No. 36 at p. 2; Whirlpool, 

No. 26 at pp. 1–3; Whirlpool, No. 34 at 

p. 2) 

AHAM, BSH, and Whirlpool noted 

that the proposed test method is not 

consistent with the approach taken by 

the European standards EN 50242/EN 

60436 and the IEC Standard 60436, 

which disregard energy and water 

consumption during water softener 

regeneration, and that the lack of 

harmonization increases test burden. 

These commenters also stated that if the 

water softener does not operate as part 

of the ‘‘normal’’ energy cycle and is user 

selectable, it should be treated like other 

options in the test procedure and should 

not be measured. (AHAM, No. 27 at p. 

4; BSH, No. 28 at pp. 2–3; BSH, No. 36 

at p. 2; Whirlpool, No. 26 at pp. 1–3; 

Whirlpool, No. 34 at p. 2) 

AHAM, BSH, and Whirlpool further 

stated that DOE overestimated the 

energy use associated with water 

softener regeneration cycles because it 

did not account for households with 

hard water that use home water 

softening systems. According to BSH, 

dishwashers with built-in water 

softening systems are the most costly 

units, and homes that can afford these 

high-end dishwashers and have water 

hardness above 180 parts per million 

(ppm) (the maximum water hardness for 

which modern phosphate-free 

detergents are effective) are more likely 

to have home water softening systems, 

although BSH did not provide 

supporting data. BSH stated that it 

produces about 50,000 units per year 

with built-in water softening systems, 

totaling a small amount of energy 

consumption for water softener 

regeneration according to the current 

waiver calculation methods. (AHAM, 

No. 27 at p. 4; BSH, No. 28 at p. 2; BSH, 

No. 36 at p. 2; Whirlpool, No. 26 at p. 

1) The NOPR/SNOPR2 Joint Comment 

stated that in the absence of data 

regarding the percentage of households 

with hard water that have their entire 

water supply softened, DOE’s 

assumption that all dishwashers with 

built-in water softeners perform the 

periodic regeneration is reasonable. 

(NOPR/SNOPR2 Joint Comment, No. 29 

at pp. 1–2) 

Whirlpool also commented that 

specifying an exact test water hardness 

of 217 mg/L (12.7 grains) would not be 

practical, and a tolerance would be 

required, such as 9 to 14 grains, 

allowing laboratories to use existing 

water supplies and reduce the 

additional test burden of special mixing 

of water for this test. (Whirlpool, No. 26 

at p. 3) 

AHAM, BSH, and Whirlpool 

commented that if DOE includes water 

softener regeneration in the test 

procedure, DOE should adopt a method 

of adding constant values for the water 

and energy use, similar to the method 

DOE agreed to in the test procedure 

waivers, which would be provided by 

the manufacturer and would account for 

regeneration frequency, water use, and 

energy use. (AHAM, No. 27 at p. 4; BSH, 

No. 28 at p. 3; BSH, No. 36 at p. 2; 

Whirlpool, No. 26 at pp. 1, 3; Whirlpool, 

No. 34 at p. 2) 

In the waivers granted to 

manufacturers for water softening 

dishwashers, DOE has already 

determined that the energy and water 

use for water softener regeneration, 

although small in comparison to the 

overall energy and water use of the 

dishwasher, must be included to 

accurately represent true energy and 

water consumption characteristics. DOE 

recognizes that the proposed 

methodology to measure water softener 

regeneration would result in a 

significant increase in testing burden, by 

requiring up to 10 additional testing 

cycles to determine the energy and 

water use associated with that process. 

The waivers granted to manufacturers of 

different water softening dishwashers 

demonstrate that the values for the 

additional water and energy 

consumption necessary for water 

softener regeneration, as well as the 

frequency of the regeneration process, 

will vary depending on the specific 

model of dishwasher. For that reason, 

DOE cannot adopt fixed values for these 

parameters in the dishwasher test 

procedure. As an alternative approach 

that will minimize significantly the 

testing burden for including water 

softener regeneration in the dishwasher 

test procedure, DOE adopts in appendix 

C1 measures of energy and water 

consumption for water softener 

regeneration using manufacturerreported values for the energy and water 

use for each regeneration cycle and the 

number of annual regeneration cycles. 

In today’s final rule, DOE also amends 

10 CFR 429.19 to require manufacturers 

to certify and submit to DOE the fixed 

values, along with data and calculations 

by which they are derived, for each 

basic dishwasher model equipped with 

a built-in water softener system. 

DOE does not have data available at 

this time to determine the percentage of 

households with hard water that have 

their entire water supply softened, and 

for that reason does not provide an 

adjustment factor to the energy and 

water use calculations adopted in 

today’s final rule. Because DOE is not 

adopting methodology for conducting 

water softener regeneration testing, but 

instead is incorporating energy and 

water use measures by means of fixed 

values, DOE is not adding any 

specification in the new dishwasher test 

procedure for the supply water 

hardness.

14The 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. 

G. Measures of Energy Consumption 

For the December 2010 NOPR, DOE 

analyzed whether it is technically 

feasible, as required by EPCA, to 

combine the existing measures of energy 

consumption for dishwashers, 

dehumidifiers, and conventional 

cooking products with standby mode 

and off mode energy use to form a single 

metric. DOE’s tentative conclusions at 

that time are discussed as follows. 

1. Dishwashers 

Because the dishwasher test 

procedure already combines measures 

of active mode energy consumption and 

a simplified measure of standby mode 

energy use to derive EAEU, the current 

energy use metric for standards, it is 

technically feasible to incorporate 

standby mode and off mode energy 

consumption into the overall energy 

efficiency descriptor. Furthermore, DOE 

noted in the December 2010 NOPR that 

its analysis of overall energy use for 

dishwashers shows that 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 . Therefore, a combined measure of 

energy efficiency for dishwashers is a 

meaningful measure. DOE proposed to 

amend the calculation of EAEU to 

incorporate the revised measures of 

standby mode and off mode energy 

consumption, and the revised EAEU 

metric would satisfy the EPCA 

requirement to integrate standby mode 

and off mode energy consumption into 

the overall energy consumption metric. 

75 FR 75290, 75314 (Dec. 2, 2010). 

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. DOE proposed 

in the December 2010 NOPR to measure 

an additional standby mode (i.e., cycle 

finished mode). However, the proposed 

amendments clarified 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. 75 FR 75290, 75314 (Dec. 2, 

2010). 

Because the current dishwasher test 

procedure already incorporates standby 

energy use in the EAOC, it is technically 

feasible to incorporate both standby 

mode and off mode energy use into the 

EAOC. Therefore, DOE proposed in the 

December 2010 NOPR to amend the 

EAOC calculation to incorporate the 

revised measures of standby mode and 

off mode energy consumption. Id. 

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 EAEU or water 

consumption per cycle (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 proposed in 

the December 2010 NOPR to add 

instructions to 10 CFR 430.23(c) 

requiring that water consumption be 

rounded to one decimal place, and 

EAEU be rounded to the nearest whole 

kWh/year. DOE also proposed at that 

time to provide rounding instructions 

for EF, but as discussed in section III.J, 

is removing provisions for determining 

EF because it is obsolete. 75 FR 75290, 

75314 (Dec. 2, 2010). 

AHAM commented that is did not 

oppose modifying the existing EAEU 

metric for dishwashers as proposed, and 

supported the rounding instructions 

proposed. (AHAM, No. 14 at p. 12) 

Whirlpool stated that, although it is 

technically feasible to create an 

integrated metric for dishwashers, delay 

start mode and cycle finished mode 

represent de-minimus contributors to 

EAEU and EAOC. According to 

Whirlpool, the annual cost of energy 

consumed in inactive/off mode would 

range from $0 to $0.65. Whirlpool stated 

that measurement of these modes adds 

cost and complication to the test 

procedure with no corresponding value, 

and should not be included in the test 

procedure. (Whirlpool, No. 12 at p. 6) 

Because integrated dishwasher energy 

use metrics are technically feasible, 

DOE revises in today’s final rule the 

EAEU and EAOC metrics in the new 

dishwasher test procedure to 

incorporate measures of standby mode 

and off mode energy use, as required by 

42 U.S.C. 6295(gg). DOE also adopts in 

10 CFR 430.23(c) the rounding 

instructions for EAEU and water 

consumption that were proposed in the 

December 2010 NOPR. 

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. 

In the December 2010 NOPR, DOE 

noted that its analysis of overall energy 

use for dehumidifiers indicates 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. Therefore, DOE stated that 

a combined measure of energy 

efficiency for dehumidifiers is a 

meaningful measure. 75 FR 75290, 

75314–15 (Dec. 2, 2010). 

DOE proposed in the December 2010 

NOPR to establish an integrated energy 

factor (IEF) measure to account for the 

product’s energy use in standby mode 

and off mode, as well as the energy use 

of the product’s main functions. DOE 

noted 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 proposed 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 14 × 24 hours)/(the 

active mode hours per year))). 75 FR 

75290, 75315 (Dec. 2, 2010). 


srobinson on DSK4SPTVN1PROD with 
65962 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

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

annual useful energy output to the total annual 

energy input. 

16 ‘‘Secondary cooking energy consumption’’ 

includes any electrical energy consumption of a 

conventional gas cooking product during active 

mode operation. 

17 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 

count the contribution of standby mode and off 

mode energy consumption. 

Section 3 of the current dehumidifier 

test procedure provides instructions for 

rounding EF to two decimal places. DOE 

proposed in the December 2010 NOPR 

to round the IEF value to two decimal 

places as well. Id. 

AHAM stated that is did not oppose 

the proposed integrated metric for 

dehumidifiers, and supports the 

rounding instructions proposed. 

(AHAM, No. 14 at p. 12) Whirlpool 

stated that, although it is technically 

feasible to create an integrated metric 

for dehumidifiers, delay start mode and 

bucket full/removed mode represent deminimus contributors to annual energy 

consumption and operating cost. 

According to Whirlpool, the annual cost 

of energy consumed in off-cycle and 

inactive modes would range from $0 to 

$0.36. Whirlpool stated that 

measurement of these modes adds cost 

and complication to the test procedure 

with no corresponding value, and 

should not be included in the test 

procedure. (Whirlpool, No. 12 at p. 6) 

Because an integrated dehumidifier 

energy use metric is technically feasible, 

DOE adopts in today’s final rule the new 

IEF metric in the new dehumidifier test 

procedure to incorporate measures of 

standby mode and off mode energy use, 

as required by 42 U.S.C. 6295(gg). DOE 

also adopts the rounding instructions 

for IEF that were proposed in the 

December 2010 NOPR. 

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.) The test procedure also 

provides a calculation for EF 15 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. 

In the December 2010 NOPR, DOE 

noted 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 

tentatively concluded that it would be 

technically feasible to incorporate 

standby mode and off mode energy 

consumption into the overall energy 

efficiency descriptor (i.e., EF). In the 

December 2010 NOPR, DOE proposed to 

establish, for conventional electric 

ovens, the ‘‘integrated annual energy 

consumption,’’ 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’’ would 

be defined as the sum of the annual 

standby mode and off mode energy 

consumption, annual secondary cooking 

energy consumption,16 and annual 

secondary self-cleaning energy 

consumption, expressed in kWh. For 

conventional electric ovens, IEF would 

be defined as the (annual useful cooking 

energy output)/(integrated annual 

energy consumption). For conventional 

gas ovens, IEF would be defined as the 

(annual useful cooking energy output)/ 

(annual gas energy consumption + 

integrated annual electrical energy 

consumption). DOE also proposed 

similar integrated annual energy 

consumption and IEF metrics for 

multiple conventional ovens (i.e., 

cooking appliances that include more 

than one conventional oven). 75 FR 

75290, 75315 (Dec. 2, 2010). 

Also in the December 2010 NOPR, 

DOE proposed to establish measures 

integrating 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’’ would 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’’ would 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 

would be defined as the annual useful 

cooking energy output divided by the 

electric cooktop integrated annual 

energy consumption. For conventional 

gas cooktops, IEF would be defined as 

the annual useful cooking energy output 

divided by the gas cooktop integrated 

annual energy consumption. Id. 

DOE proposed in the December 2010 

NOPR to establish the following 

measures of energy consumption for 

conventional kitchen ranges (i.e., a 

cooktop and oven combined). 

‘‘Integrated annual energy 

consumption’’ would 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.17 The IEF of a kitchen 

range would 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. 75 FR 75290, 

75315–16 (Dec. 2, 2010). 

DOE is also proposed in the December 

2010 NOPR 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. 75 FR 75290, 75316 (Dec. 2, 

2010). 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 proposed in the December 

2010 NOPR 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. 75 FR 

75290, 75316 (Dec. 2, 2010). 

AHAM commented that is did not 

oppose the proposed integrated metrics 

for conventional cooking products, and 

supports the rounding instructions 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65963 

proposed. (AHAM, No. 14 at p. 12) 

Whirlpool stated that, although it is 

technically feasible to create an 

integrated metric for conventional 

cooking products, delay start mode, 

cycle finished mode, and Sabbath mode 

represent de-minimus contributors to 

annual energy consumption and 

operating cost. Whirlpool stated that 

measurement of these modes adds cost 

and complication to the test procedure 

with no corresponding value, and 

should not be included in the test 

procedure. (Whirlpool, No. 12 at p. 6) 

ASAP stated that an integrated metric 

for conventional cooking products could 

preclude the possibility of a future 

standard for standby energy use for 

conventional cooking products, as is 

being considered for microwave ovens. 

(ASAP, NOPR Public Meeting 

Transcript, No. 10 at p. 120. 

Because integrated energy use metrics 

for conventional cooking products are 

technically feasible, DOE adopts in 

today’s final rule new IEF and 

integrated annual energy consumption 

metrics in the cooking products test 

procedure as described to incorporate 

measures of standby mode and off mode 

energy use, as required by 42 U.S.C. 

6295(gg). The cooking products test 

procedure amendments also include 

separate measures of standby mode and 

off mode energy use that feed into the 

calculation of IEF. Should DOE in the 

future consider new energy efficiency 

standards for conventional cooking 

products, DOE will take appropriate 

action consistent with 42 U.S.C. 

6295(gg). DOE also amends in 10 CFR 

430.23(i) the estimated annual energy 

cost calculations to include the cost of 

energy consumed in standby mode and 

off mode for conventional cooking 

products, as well as to provide rounding 

instructions for EAOC and IEF as 

proposed in the December 2010 NOPR. 

H. Dishwasher Test Procedure 

Clarifications 

1. Energy Test Cycle Selection and 

Normal Cycle Definition 

DOE proposed in the May 2012 

SNOPR that soil-sensing dishwashers be 

tested on the normal cycle under section 

2.6.3 of appendix C if soil-sensing is 

available as an option in the normal 

cycle. If soil-sensing is not available for 

the normal cycle, DOE proposed that the 

dishwasher be tested by selecting the 

cycle type that uses the soil-sensing 

system, and contains all the elements of 

a normal cycle including the power-dry 

feature (if such a feature is provided). 77 

FR 31444, 31452–53 (May 25, 2010). 

DOE continued to propose this 

clarification in the August 2012 SNOPR 

and further proposed that, for units with 

multiple temperature options, the unit 

shall be tested at the manufacturerrecommended setting, or absent a 

manufacturer recommendation, at the 

highest temperature setting. 77 FR 

49064, 49065–66 (Aug. 15, 2012). 

AHAM, BSH, and Whirlpool opposed 

the proposals in the May 2012 SNOPR 

and the August 2012 SNOPR, stating 

that it contradicts the definition of 

normal cycle, may not represent typical 

consumer usage, and creates confusion 

for the tester and consumer. These 

commenters stated that the ‘‘normal 

cycle’’ is the appropriate energy test 

cycle, and manufacturers must assume 

the consumer will use the manufacturerrecommended cycle even if that cycle is 

non-soil-sensing on a dishwasher 

capable of soil-sensing. The commenters 

further stated that manufacturers may 

do this in order to provide soil-sensing 

only on a specialty cycle(s), such as the 

cycle intended for washing pots and 

pans, and then recommend the non-soilsensing normal cycle to completely 

wash a full load of normally soiled 

dishes. Additionally, AHAM, BSH, and 

Whirlpool noted that it is difficult to 

determine which cycles use the soil 

sensor. (AHAM, No. 27 at pp. 4–6; BSH, 

No 28. at pp. 3–4; Whirlpool, No. 26 at 

p. 1; Whirlpool, 2012 Public Meeting 

Transcript, No. 38 at pp. 88–89) AHAM 

commented that DOE issued guidance 

in 2010 stating that a soil-sensing cycle 

is to be used, even if the normal cycle 

is fixed. AHAM stated that to some, this 

guidance changed the interpretation of 

the test procedure. (AHAM, 2012 Public 

Meeting Transcript, No. 38 at pp. 85–86) 

Additionally, AHAM, BSH, Samsung, 

and Whirlpool pointed out that a 

manufacturer may make multiple 

recommendations for cycles that would 

completely wash a full load of normally 

soiled dishes, which could invite 

manufacturer recommendation of 

alternative cycles or option 

combinations that could be interpreted 

by consumers to be alternatives to the 

‘‘normal cycle’’. These commenters 

stated it is therefore logical that the 

energy test cycle and ‘‘normal cycle’’ 

should be the cycle most commonly 

used by consumers on an everyday 

basis. Accordingly, AHAM, BSH, and 

Whirlpool suggested that the definition 

of ‘‘normal cycle’’ be revised to clarify 

that intent, and to encourage 

manufacturers to recommend cycles to 

the consumer that are consistent with 

the energy and water use measured by 

the test procedure. In response to the 

May 2012 SNOPR, they proposed the 

following definition for normal cycle: 

‘‘normal cycle means the cycle type 

recommended by the manufacturer for 

daily, regular, or typical use to 

completely wash a full load of normally 

soiled dishes, including the power-dry 

feature. If multiple cycles are 

recommended by the manufacturer for 

daily, regular, or typical use to 

completely wash a full load of normally 

soiled dishes, the most energy intensive 

of those recommended cycles shall be 

considered the normal cycle for the 

purposes of this test procedure.’’ AHAM 

and Whirlpool opposed the 

specification of temperature options in 

the normal cycle definition, but 

commented that if DOE adds 

temperature options to that definition, 

DOE should require selection of the 

highest temperature settings in the 

absence of manufacturer 

recommendations. BSH also supported a 

requirement to select the highest 

temperature settings in the absence of 

manufacturer recommendations. AHAM 

and Whirlpool stated that, in the 

absence of data indicating which 

temperature settings are most 

representative of actual consumer use, 

consumers could select the highest 

temperature settings. (AHAM, No. 27 at 

pp. 5–6; AHAM, No. 35 at p. 6; BSH, 

No. 28 at pp. 3–4; BSH, No. 36 at p. 2; 

Samsung, No. 33 at p. 1; Whirlpool, No. 

26 at pp. 1, 4; Whirlpool, No. 32 at p. 

1) 

In response to DOE’s updated 

proposal for the definition of ‘‘normal 

cycle’’ in the August 2012 SNOPR, 

AHAM, BSH, Samsung, and Whirlpool 

submitted a revised definition which 

would state that the ‘‘[n]ormal cycle 

means the cycle type recommended in 

the manufacturer’s instructions for 

daily, regular, or typical use to 

completely wash a full load of normally 

soiled dishes, including the power-dry 

feature. If no cycle or more than one 

cycle is recommended in the 

manufacturer’s instructions for daily, 

regular, or typical use to completely 

wash a full load of normally soiled 

dishes, the most energy intensive of 

these cycles shall be considered the 

normal cycle for purposes of this test 

procedure.’’ (AHAM, No. 35 at p. 6; 

BSH, No. 36 at pp. 2–3; Samsung, No. 

33 at p. 1; Whirlpool, No. 32 at p. 1) 

Whirlpool commented that DOE 

should include a ‘‘statement of intent’’ 

in the dishwasher test procedure to 

clarify the test procedure for new 

technology developments, and to 

prevent manufacturers from creating a 

specifically designed test cycle that fails 

to perform the functions desired by the 

consumer, similar to a recent 

refrigerator rulemaking. (Whirlpool, No. 

26 at pp. 3–4; Whirlpool, No. 32 at pp. 

1–2) Samsung also requested that DOE 

add a statement of intent to help 


srobinson on DSK4SPTVN1PROD with 
65964 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

manufacturers, certification bodies, and 

consumers understand that the intent of 

the energy test cycle selection is to 

reflect the representativeness of the test 

procedure to consumer use conditions. 

(Samsung, No. 33 at p. 1) According to 

BSH, however, any additional 

statements of intent and/or additional 

wording seeking to further clarify the 

definition may, in some cases, result in 

confusion as to what cycle should be 

selected for testing. (BSH, No. 36 at p. 

2) 

Under EPCA, any test procedure for 

consumer products that DOE prescribes 

or amends shall be reasonably designed 

to produce test results which measure 

energy consumption or energy 

efficiency of these products during a 

representative average use cycle or 

period of use. (42 U.S.C. 6293(b)(3)) 

DOE is aware of products available on 

the market that have multiple cycles 

recommended by the manufacturer for 

washing a full load of normally soiled 

dishes, and that for soil-sensing 

dishwasher these cycles may be soilsensing or non-soil sensing. Upon 

consideration of the arguments put forth 

by commenters that consumers are most 

likely to select cycles that are 

recommended by the manufacturer 

when washing a full load of normally 

soiled dishes, DOE determines that it 

would be contrary to the EPCA 

requirements if DOE were to require the 

preferential selection of a soil-sensing 

cycle for a soil-sensing dishwasher, 

regardless of the manufacturer’s 

instructions to the consumer. Therefore, 

DOE agrees with the stakeholder 

recommendation for the definition of 

normal cycle, including the requirement 

to test on the most energy-intensive of 

multiple recommended cycles or, in the 

absence of a manufacturer 

recommendation, the most energyintensive of all cycles. Because the most 

energy-intensive cycle would include 

the highest energy consumption 

temperature options for washing and 

drying, DOE includes such a 

clarification in the definition of the 

normal cycle in appendix C1, which 

would be required to be used on the 

compliance date of any final amended 

standards for dishwashers (i.e., May 30, 

2013 unless the direct final rule issued 

on May 30, 2012 is withdrawn). On that 

compliance date, the definition of 

normal cycle that DOE adopts in today’s 

final rule supersedes the 2010 guidance. 

For the reasons discussed above, DOE 

withdraws the guidance effective May 

30, 2013 (unless the direct final rule 

issued on May 30, 2012 is withdrawn, 

in which case the guidance will remain 

in effect). DOE also clarifies in appendix 

C1 that ‘‘non-soil-sensing dishwasher’’ 

refers to a dishwasher that does not 

have the ability to adjust automatically 

any energy consuming aspect of the 

normal cycle based on the soil load of 

the dishes, and that a ‘‘soil-sensingdishwasher’’ does have the ability to 

adjust automatically any energy 

consuming aspect of the normal cycle 

based on the soil load of the dishes. In 

addition, DOE clarifies that soil-sensing 

dishwashers shall be tested on the 

normal cycle. Furthermore, DOE has not 

included a statement of intent in the 

amendments to the dishwasher test 

procedure adopted in today’s final rule. 

EPCA’s requirement that test procedures 

measure energy efficiency, energy use or 

water use during a representative 

average use cycle obviates the need for 

specific clarification of that purpose in 

the residential dishwasher test 

procedure in the absence of any 

indication that manufacturers are 

designing products that test under 

conditions different than those used by 

the consumer. 

AHAM, BSH, and Whirlpool 

recommend that manufacturers be 

required to submit with their 

certification reports: (1) Whether the 

unit is soil-sensing; (2) the cycle 

selected for the energy test; and (3) the 

options selected for the energy test. 

AHAM also recommended 

manufacturers certify in the report 

whether the test cycle is soil-sensing. 

AHAM, BSH, and Whirlpool suggested 

that manufacturers include a clear 

recommendation for the cycle setting 

and options in their use and care guides, 

or on the product controls. (AHAM, No. 

27 at p. 6; AHAM, 2012 Public Meeting 

Transcript, No. 38 at p. 87; BSH, No. 28 

at pp. 4–5; BSH, 2012 Public Meeting 

Transcript, No. 38 at pp. 91–92; 

Whirlpool, No. 26 at p. 1) Intertek 

commented that currently, the only way 

for laboratories to know if a unit has a 

soil sensor is to reference the use and 

care manual. (Intertek, 2012 Public 

Meeting Transcript, No. 38 at p. 91) BSH 

and Whirlpool indicated that their user 

manuals likely indicate whether a unit 

has a soil sensor, while GE noted their 

manuals do not necessarily indicate 

which cycles are soil-sensing, and 

which are fixed. (BSH, 2012 Public 

Meeting Transcript, No. 38 at p. 92; 

Whirlpool, 2012 Public Meeting 

Transcript, No. 38 at p. 92; GE, 2012 

Public Meeting Transcript, No. 38 at p. 

98) 

DOE notes that the certification 

requirements for dishwashers included 

in 10 CFR part 429.19 require 

manufacturers to report the following 

information for each certified basic 

model: the capacity in number of place 

settings as specified in ANSI/AHAM 

DW–1, presence of a soil sensor (if yes, 

the number of cycles required to reach 

calibration), and the water inlet 

temperature used for testing in °F. In 

today’s final rule, DOE determined, for 

reproducibility of the test procedure, to 

additionally require that manufacturers 

submit the cycle used for energy testing, 

whether that cycle is soil-sensing, and 

the options selected for that cycle 

during energy testing. 

2. Preconditioning 

In the May 2012 SNOPR, DOE 

proposed that, for soil-sensing 

dishwashers, the cycle setting for the 

active mode cycle (in which the soil 

sensor is active) be selected for the 

preconditioning cycle. 77 FR 31444, 

31452 (May 25, 2012). In the August 

2012 SNOPR, DOE additionally 

proposed requiring two preconditioning 

cycles to ensure the soil sensor is 

properly calibrated, and to clean any 

debris out of the dishwasher prior to 

testing. 77 FR 49064, 49066 (Aug. 15, 

2012). 

AHAM, BSH, Samsung, and 

Whirlpool agreed with using the test 

cycle for preconditioning, but also 

commented that the definition of 

preconditioning is vague and not 

adequate for the way some products 

operate today. They commented that the 

proposed language may be confusing, 

and recommended that the cycle used 

for preconditioning be the same as the 

cycles used for the test. (AHAM, No. 27 

at p. 9; AHAM, No. 35 at p. 7; AHAM, 

2012 Public Meeting Transcript, No. 38 

at pp. 107–108; BSH, No. 36 at p. 3; 

BSH, No. 28 at p. 7; Samsung, No. 33 

at p. 1; Whirlpool, No. 26 at p. 1; 

Whirlpool, No. 32 at p. 1) AHAM, BSH, 

Samsung, and Whirlpool also support 

the requirement for two preconditioning 

cycles. (AHAM, No. 35 at p. 7; BSH, No. 

36 at p. 3; Samsung, No. 33 at p. 1; 

Whirlpool, No. 32 at p. 1) Whirlpool 

and BSH commented that some 

laboratories perform more than one 

preconditioning cycle to ensure that the 

machine is cleaned out and water usage 

is quantified, although Whirlpool’s 

products are designed so that the sensor 

calibrates in one cycle. Whirlpool 

acknowledged, however, that if its 

dishwasher does not calibrate in the 

first cycle, then it uses the next cycle as 

well, and will keep trying on 

subsequent cycles if there is still an 

error. BSH commented that the action 

taken if the sensor fails to calibrate on 

the first cycle varies from manufacturer 

to manufacturer. Whirlpool and BSH 

stated that they have equipment in their 

own laboratories that can determine 

whether the sensor has calibrated, but 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65965 

they further noted that there is not a 

clear way for a third-party laboratory to 

determine whether the sensor had 

calibrated, because the energy and water 

use that would indicate a calibration 

process are model-specific and the 

sensor responses are complex. 

According to BSH, sensor responses 

may include changes in motor speed 

and water temperatures, as well as water 

consumption. Whirlpool and BSH 

added that their sensors are designed to 

calibrate with clean water, rather than 

with a soiled load. (BSH, 2012 Public 

Meeting Transcript, No. 38 at pp. 111– 

113, 115–116, 118; Whirlpool, 2012 

Public Meeting Transcript, No. 38 at pp. 

109–115, 117, 119–120) Viking Range 

Corporation (Viking) commented that 

user manuals typically contain energy 

use information for cycles that would 

provide an indication to a laboratory as 

to whether a calibration occurred. 

(Viking, 2012 Public Meeting 

Transcript, No. 38 at pp. 120–121) BSH 

stated that it provides a minimum and 

maximum water consumption, but 

water use above the maximum is not 

necessarily indicative of a problem with 

calibration. (BSH, 2012 Public Meeting 

Transcript, No. 38 at p. 122) UL stated 

that it performs one preconditioning 

cycle because that is the 

recommendation in ANSI/AHAM DW– 

1. (UL, 2012 Public Meeting Transcript, 

No. 38 at p. 123) 

DOE has determined that specifying 

the energy test cycle would provide 

clarity and the most accurate possible 

water usage measurement for 

calculation of detergent dosing. Thus, in 

appendix C1 established by today’s final 

rule, DOE includes the requirement that 

the preconditioning cycle be conducted 

using the same cycle setting as the 

energy test cycle, as proposed in the 

May 2012 SNOPR and August 2012 

SNOPR. DOE has added further 

clarification by revising the definition 

for ‘‘preconditioning cycle’’ to state that 

it is a normal cycle run with no test load 

to ensure that the water lines and sump 

area of the pump are primed. DOE also 

determines that there would be a slight 

additional test burden of conducting 

two preconditioning cycles, but that this 

increase is warranted by the 

improvement in test measurements by 

ensuring sensor calibration and cleaning 

out the machine and is not unduly 

burdensome to conduct, as discussed in 

section III.K. In addition, specifying two 

preconditioning cycles would eliminate 

the need for laboratories to interpret 

testing data to determine whether sensor 

calibration occurred successfully after 

the first preconditioning, thus 

improving reproducibility of the test 

procedure. For these reasons, DOE is 

requiring the use of two preconditioning 

cycles in the dishwasher test procedure 

established at appendix C1. 

3. Detergent 

In the May 2012 SNOPR, DOE 

proposed determining detergent dosing 

using the pre-wash and main wash fill 

volumes during the preconditioning 

cycle, and outlined the calculations for 

the proper dosing. Additionally, the 

proposal updated the type of detergent 

to the currently-available ‘‘Cascade with 

the Grease Fighting Power of Dawn’’ 

powder detergent. 77 FR 31444, 31453 

(May 25, 2012). In the August 2012 

SNOPR, DOE continued to propose 

detergent dosing as outlined in the May 

2012 SNOPR, with the clarification that 

the pre-wash and main wash fill 

volumes be recorded during the second 

proposed preconditioning cycle. 77 FR 

49064, 49066 (Aug. 15, 2012). 

AHAM commented that the proposed 

detergent dosage calculation leaves 

room for interpretation. (AHAM, 2012 

Public Meeting Transcript, No. 38 at p. 

93) AHAM, BSH, and Whirlpool 

commented that the concentration 

approach for detergent dosing may no 

longer be representative of actual 

consumer use because consumers are 

more likely to use a monodose 

detergent. AHAM, BSH, and Whirlpool 

recommended that DOE should base the 

decision about whether to specify a 

certain amount of powder detergent or 

a unitized dose such as a tablet on 

consumer usage data, and cited an AC 

Nielson Homescan Panel study which 

found a trend towards monodose 

detergents from 2000 to 2011. According 

to these commenters, the study showed 

that dishwasher detergent usage was 

14.5 percent monodose, 39 percent gel, 

and 46.5 percent powder in 2000, which 

shifted to 53.5 percent monodose, 28.5 

percent gel, and 18 percent powder in 

2011. AHAM, BSH, and Whirlpool 

stated that a fixed detergent dose in the 

dishwasher test procedure would be 

more representative of consumer usage, 

less burdensome, and more accurate 

than the powder detergent dosage 

currently required, which can vary from 

test to test due to its complexity. AHAM 

and Whirlpool further commented that 

DOE may also consider consumer use of 

monodose tablets including rinse aid. 

(AHAM, No. 27 at pp. 10–11; BSH, No. 

28 at pp. 7–8; Whirlpool, 2012 Public 

Meeting Transcript, No. 38 at pp. 94, 

96–97; Whirlpool, No. 26 at p. 1) 

AHAM, BSH, and Whirlpool 

commented that DOE should consider 

whether the detergent should be a 

laboratory formulation or a formulation 

available on the market. (AHAM, No. 27 

at p. 10; BSH, No. 28 at pp. 7–8; 

Whirlpool, No. 26 at p. 1) BSH proposed 

that DOE consider an IEC test detergent 

to eliminate variation due to 

manufacturing tolerances and 

formulation changes. (BSH, No. 28 at p. 

8) In the interim, however, without a 

consumer use study, AHAM, BSH, and 

Whirlpool support DOE’s proposal to 

update the detergent requirement to the 

‘‘Cascade with the Grease Fighting 

Power of Dawn’’ formulation powder 

detergent. AHAM and BSH commented, 

though, that DOE would need to 

consider how a phosphate-free detergent 

would affect energy and water use 

results. (AHAM, No. 27 at p. 10; AHAM, 

2012 Public Meeting Transcript, No. 38 

at pp. 93–94; BSH, No. 28 at p. 8; 

Whirlpool, No. 26 at p. 1) 

BSH noted that detergent dosing 

based on the preconditioning cycle with 

a clean load may not reflect the amount 

of water that would be used during a 

test cycle with a soiled load, and that 

the food load and soil sensors will affect 

each other. BSH also commented that 

the detergent can influence the sensor 

decision. (BSH, 2012 Public Meeting 

Transcript, No. 38 at pp. 94–96, 99) 

DOE has determined to adopt the 

concentration specification for ‘‘Cascade 

with the Grease Fighting Power of 

Dawn’’ rather than the other detergent 

dosing methods. A monodose detergent 

would result in the same amount of 

detergent being dispensed for every 

dishwasher, regardless of water 

consumption. This may skew test 

results for dishwashers with either high 

or low water consumption due to the 

changes in detergent concentration that 

could impact how easily soils are 

removed from the test load. A 

concentration-based detergent dosing 

ensures that the detergent concentration 

is similar from unit-to-unit. 

Additionally, DOE does not have any 

information indicating that this 

phosphate-free detergent would have 

any impact on energy and water use 

results. DOE notes that the detergent 

specified in ANSI/AHAM DW–1–1992 

has been unavailable for a number of 

years. DOE understands that 

manufacturers and third-party test 

laboratories have used ‘‘Cascade with 

the Grease Fighting Power of Dawn’’ in 

its absence, with no apparent impact in 

the resulting energy and water 

consumption results. 

DOE acknowledges that the water 

consumption in the second 

preconditioning cycle with no soil load 

may be different from the water 

consumed during the test cycle. 

However, running a soiled load with no 

detergent to determine water 

consumption may also yield water 


srobinson on DSK4SPTVN1PROD with 
65966 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

consumptions different from the test 

cycle due to the lack of detergent and 

less-effective removal of soils from the 

test load. The method of basing 

detergent dosing on the preconditioning 

water consumptions helps to limit test 

burden for manufacturers and thirdparty test laboratories. Additionally, the 

requirement to run the preconditioning 

cycle on the same setting as the test 

cycles would likely lead to similar water 

consumptions for both preconditioning 

and testing. 

Therefore, DOE continues to include 

the concentration-based detergent 

calculation using the pre-wash and 

main wash water consumptions as 

measured during the second 

preconditioning cycle, and to update the 

detergent specification to ‘‘Cascade with 

the Grease Fighting Power of Dawn’’ for 

appendix C1 in today’s final rule. DOE 

also amends appendix C to specify the 

detergent as ‘‘Cascade with the Grease 

Fighting Power of Dawn’’ because the 

currently specified detergent is no 

longer available, thereby making such 

specification obsolete. 

4. Power Supply Requirements 

In the May 2012 SNOPR, DOE 

proposed that power be continuously 

supplied to the unit during testing, 

including after the preconditioning 

cycle and between all test cycles. 77 FR 

31444, 31452 (May 25, 2012). The 

August 2012 SNOPR updated the 

proposed continuous power supply 

requirement to also cover the second 

preconditioning test cycle proposed to 

ensure sensor calibration. 77 FR 49064, 

49066 (Aug. 15, 2012). 

AHAM, BSH, and Whirlpool 

commented that the requirement to 

maintain the power supply throughout 

testing would add test burden for 

manufacturers who know that their soil 

sensors do not lose calibration with an 

interruption in the power supply. The 

commenters suggested DOE add a note 

to the test procedure that some soil 

sensors may lose calibration, so that 

third-party test laboratories would be 

aware of this behavior, without 

including the requirement to maintain 

the power supply. This would allow 

manufacturers to avoid unnecessary test 

burden. (AHAM, No. 27 at p. 7; BSH, 

No. 28 at p. 5; Whirlpool, No. 26 at p. 

1) 

DOE understands that maintaining the 

power supply represents an increase in 

test burden for manufacturers of units 

whose soil sensors do not lose 

calibration. However, given the 

difficulty in determining whether a soil 

sensor is calibrated, DOE includes the 

continuous power supply requirement 

in appendix C1 to ensure consistent 

testing by either a manufacturer or a 

third-party laboratory. 

5. Updated Industry Standard 

In response to the May 2012 SNOPR, 

AHAM, BSH, and Whirlpool 

commented that DOE should 

incorporate by reference the most recent 

versions of external test procedures, 

including ANSI/AHAM DW–1–2009 (or 

the latest version of DW–1 at the time 

DOE updates its incorporation by 

reference). These commenters stated 

that DOE would need to determine 

whether this change would result in 

changes to measured energy (resulting 

from a change in dishware, for 

example). AHAM and Whirlpool also 

noted that there are differences in the 

food soils specified, although Whirlpool 

characterized them as ‘‘fairly subtle.’’ 

(AHAM, No. 27 at pp. 12–13; AHAM, 

2012 Public Meeting Transcript, No. 38 

at pp. 155–156; BSH, No. 28 at p. 10;

No. 38 at p. 156; Whirlpool, No. 26 at 

pp. 1, 5; Whirlpool, 2012 Public 

Meeting Transcript, No. 38 at p. 156) 

In response to these comments, for the 

August 2012 SNOPR, DOE proposed to 

update the industry standard test 

reference in appendix C from ANSI/ 

AHAM DW–1–1992 to DW–1–2010. 77 

FR 49064, 49066 (Aug. 15, 2012). 

AHAM, BSH, Samsung, and 

Whirlpool support the proposal to 

update the industry standard reference 

to ANSI/AHAM DW–1–2010, but noted 

they do not currently have data on the 

effect on energy use of changing to the 

updated version of the standard. These 

commenters stated that DOE must 

determine whether there would be 

changes to the measured energy use. 

(AHAM, No. 35 at pp. 7–8; BSH, No. 36 

at p. 3, Samsung, No. 33 at p. 1; 

Whirlpool, No. 32 at p. 1) 

The DOE dishwasher test procedure 

references certain sections of ANSI/ 

AHAM DW–1 related to soil preparation 

and application. Differences in other 

provisions such as the dishware 

specifications would not impact the 

measurement of energy and water use 

under the DOE test. When DOE 

compared the relevant sections of 1992 

and 2010 versions of the standard, it 

identified the following differences: 

• The brand and product description 

for the coffee and preserves; 

• The preparation method for the eggs 

and cream corn; 

• The amount of reconstituted milk 

used in the potato mixture; 

• The grinding specifications for the 

ground beef; and 

• The order of soil application. 

DOE has not been presented with any 

data or information that would show 

that these differences would impact the 

results from the DOE dishwasher test 

procedure for specific dishwasher 

models. DOE also notes the uniform 

support from commenters to reference 

the most recent version of industry 

standards in its test procedures and 

observes that some test laboratories are 

already conducting dishwasher testing 

according to ANSI/AHAM DW–1–2010. 

Further, these amendments will not be 

required until the compliance date of 

new standards, which will be May 30, 

2013, unless the direct final rule is 

withdrawn. If manufacturers determine 

that the new DOE test procedure does 

not measure energy and water use that 

is representative for their products, they 

may submit to DOE a petition for waiver 

from the DOE test procedure to 

determine an appropriate method. For 

the reasons discussed above, DOE has 

decided to update the reference in its 

dishwasher test procedure at appendix 

C1 to ANSI/AHAM DW–1–2010 in 

today’s final rule. 

6. Water Pressure 

As noted in the August 2012 SNOPR, 

DOE received comments in response to 

the May 2012 SNOPR regarding 

transient water pressure drop when the 

water supply valve first opens. AHAM, 

BSH, and Whirlpool commented that 

laboratories interpret differently how 

and where the water pressure is 

measured and controlled. These 

commenters recommended that, for 

repeatability and reproducibility, DOE 

should specify that the water pressure 

drops to the required 35 pounds per 

square inch gauge (psig) ± 2.5 psig in no 

more than 2 seconds after the valve 

opens. According to AHAM, its 

members and independent laboratories 

indicated that this is the minimum 

length of time that they are capable of 

achieving. (AHAM, No. 27 at p. 12; 

AHAM, 2012 Public Meeting Transcript, 

No. 38 at p. 137; BSH, No. 28 at p. 9; 

BSH, 2012 Public Meeting Transcript, 

No. 38 at p. 158; Whirlpool, No. 26 at 

p. 1) Samsung noted that the time for 

the transient pressure drop should be 

minimized so that it does not affect a 

water fill, since the fill time can be 

approximately 1 minute. (Samsung, 

2012 Public Meeting Transcript, No. 38 

at pp. 139–140) According to Whirlpool, 

the height at which the pressure 

measurement is made affects the 

measurement, although not 

significantly. (Whirlpool, 2012 Public 

Meeting Transcript, No. 38 at p. 137) 

In the August 2012 SNOPR, DOE 

acknowledged that transient pressure 

variations should be minimized for 

reasons of test stability and 

reproducibility, and, based on 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65967 

commenters’ indication of laboratory 

capabilities, proposed that the specified 

pressure be achieved within 2 seconds. 

77 FR 49064, 49066 (Aug. 15, 2012). 

AHAM, BSH, Samsung, and Whirlpool 

supported this proposal, reiterating that 

the duration of the pressure drop should 

be limited to ensure that water is 

flowing into the dishwasher at the 

proper pressure and that AHAM’s 

members indicated that 2 seconds is the 

minimum length of time their 

laboratories can achieve. (AHAM, No. 

35 at p. 8; BSH, No. 36 at p. 3, Samsung, 

No. 33 at p. 1; Whirlpool, No. 32 at p. 

1) 

In consideration of these comments 

and for the reasons already noted, DOE 

adopts in today’s final rule the 

requirement in the new dishwasher test 

procedure that the water pressure shall 

be achieved within 2 seconds of 

opening the water supply valve. DOE is 

not requiring the pressure to be 

measured at a particular location 

because DOE did not receive sufficient 

information regarding a representative 

position or the impact of pressure 

measurement position on the energy 

and water use results. 

7. Water Hardness 

DOE received comments in response 

to the May 2012 SNOPR and the August 

2012 SNOPR that DOE should add a 

water hardness specification to the 

dishwasher test procedure. AHAM, 

BSH, Samsung and Whirlpool 

commented that DOE should reference 

the water hardness specification in 

ANSI/AHAM DW–1–2010 of 0 to 5 

grains, or 0 to 85 ppm, to reduce test 

variation. (AHAM, No. 27 at p. 11; 

AHAM, No. 35 at p. 10; BSH, No. 28 at 

p. 9; Samsung, No. 33 at p. 1; Whirlpool, 

No. 26 at pp. 1, 5) AHAM and 

Whirlpool further clarified that the 

American Water Works Association 

found this to be the normal range 

occurring in municipal water supplies, 

and Whirlpool stated that the water 

hardness specification was intended to 

reduce lab-to-lab test variation. (AHAM, 

No. 27 at p. 11; Whirlpool, No. 26 at p. 

1; Whirlpool, 2012 Public Meeting 

Transcript, No. 38 at pp. 148–150) 

Whirlpool later changed its 

recommendation for a water hardness 

requirement to a range of 0 to 2 grains, 

or 0 to 34 ppm, based on total hardness 

and not just calcium carbonate, to 

account for magnesium as well. 

According to Whirlpool, laboratories 

can control water hardness to this range 

with water softening systems. 

(Whirlpool, No. 34 at p. 2) UL 

commented that varying between soft 

and hard water could potentially impact 

test results. (UL, 2012 Public Meeting 

Transcript, No. 38 at p. 151) AHAM 

noted that in the process of developing 

an ENERGY STAR test method for 

dishwasher cleaning performance, DOE 

proposed to adopt the water hardness 

requirement in ANSI/AHAM DW–1– 

1992. (AHAM, 2012 Public Meeting 

Transcript, No. 38 at pp. 146–147) 

DOE proposed a water hardness 

requirement as part of the ENERGY 

STAR test method for evaluating 

dishwasher cleaning performance 

because it may have an impact on 

cleaning performance. However, DOE is 

not aware of data indicating how 

variations in water hardness may impact 

energy and water consumption under 

the DOE test procedure, and, therefore, 

is not adopting a water hardness 

requirement in the test procedure at this 

time. DOE may consider this topic in a 

future rulemaking if such data become 

available. 

8. Drain Height 

AHAM noted at the 2012 Public 

Meeting that the height of the 

dishwasher drain is not currently 

specified in the DOE test procedure, and 

that such a specification should be 

added to reduce testing variability. 

AHAM, BSH, and Whirlpool 

subsequently proposed in their 

comments on the May 2012 SNOPR that 

the drain height should be specified per 

the manufacturer installation 

instructions. In the absence of such 

instructions, these commenters 

recommended a drain height of 20 

inches. (AHAM, No. 27 at p. 11; AHAM, 

2012 Public Meeting Transcript, No. 38 

at p. 141; BSH, No. 28 at pp. 8–9; 

Whirlpool, No. 26 at p. 1) 

In the August 2012 SNOPR, DOE 

agreed that the use of manufacturer’s 

instructions for drain height, or a 

standard height in the absence of such 

information, would improve 

reproducibility of the test and proposed 

corresponding amendments to the 

dishwasher test procedure, including a 

standard drain height of 20 inches. 77 

FR 49064, 49066 (Aug. 15, 2012). 

AHAM, BSH, Samsung, and 

Whirlpool supported the proposed 

approach to require installation of the 

dishwasher with a drain height as 

specified in the manufacturer’s 

instructions, and that in the absence of 

such instructions, the drain height 

should be a standard level of 20 inches. 

(AHAM, No. 35 at p. 8; BSH, No. 36 at 

p. 3; Samsung, No. 33 at p. 1; Whirlpool, 

No. 32 at p. 1) For reasons of test 

reproducibility and in the absence of 

comments objecting to this approach, 

DOE includes the drain height 

requirements in the new dishwasher test 

procedure in today’s final rule 

according to the proposal in the August 

2012 SNOPR. 

9. Test Load Specifications and Soiling 

Requirements, Including Obsolete 

Dishware and Food Items 

In the May 2012 SNOPR, DOE 

observed that the requirement for soilsensing dishwashers in the current DOE 

test procedure to soil a certain number 

of place settings, while leaving the 

remaining place settings, serving pieces, 

and all flatware in the test load unsoiled 

could be ambiguous because the test 

procedure does not define which items 

a ‘‘place setting’’ comprises. Therefore, 

DOE proposed to amend section 2.7 of 

appendix C to specify the individual 

items in a place setting and to identify 

the serving pieces, as well as to clarify 

in section 2.6.3 of appendix C that the 

flatware that is part of a soiled place 

setting is to remain unsoiled. 77 FR 

31444, 31453 (May 25, 2012). DOE 

maintained this proposal for the August 

2012 SNOPR. AHAM, BSH, and 

Whirlpool commented that the test 

procedure was already clear in requiring 

that the flatware is not to be soiled, but 

did not object to the proposed 

clarification. (AHAM, No. 27 at pp. 7– 

8; BSH, No. 28 at p. 6; Whirlpool, No. 

26 at p. 1) DOE has therefore included 

these amendments to section 2.7 and 

2.63 of the new dishwasher test 

procedure at appendix C1 in today’s 

final rule. 

In the May 2012 SNOPR, DOE also 

identified a number of test items, 

including the cup and saucer, salad 

fork, serving fork, and serving spoon, 

which are no longer available, thereby 

making such specifications obsolete. 

DOE noted that AHAM had submitted 

information providing alternative 

specifications for all flatware and 

serving pieces, which DOE proposed as 

amendments to the test load 

specifications in section 2.7 of appendix 

C. DOE also sought comment on 

alternative specifications for other 

obsolete test items, such as the cup and 

saucer. 

AHAM, BSH, and Whirlpool noted 

the importance to manufacturers and 

third-party laboratories of identifying 

replacement test load items swiftly to 

run the test and certify compliance 

properly. AHAM and BSH supported 

DOE’s proposal for replacements to 

obsolete flatware and serving pieces. 

AHAM and BSH noted, however, that 

although the cup and saucer are 

obsolete, alternatives may be available 

from the same source but with a new 

item number. These commenters also 

suggested that the bread and butter plate 

and fruit bowl may become obsolete. 

(AHAM, No. 27 at pp. 7–8; BSH, No. 28 


srobinson on DSK4SPTVN1PROD with 
65968 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

at pp. 5–6; Whirlpool, No. 26 at pp. 1, 

5) 

In addition to comments on the 

obsolete test load items, DOE received 

comments on obsolete food items for the 

soil requirements. AHAM, BSH, and 

Whirlpool stated that the margarine 

specified in the current dishwasher test 

procedure was no longer available, and 

proposed a replacement brand and 

product formulation even though it is 

not possible to determine if the 

replacement margarine would impact 

measured energy use. (AHAM, No. 27 at 

p. 8; AHAM, 2012 Public Meeting 

Transcript, No. 38 at pp. 101–102; BSH, 

No. 28 at p. 6; BSH, 2012 Public 

Meeting Transcript, No. 38 at pp. 102– 

103; Whirlpool, No. 26 at p. 1; 

Whirlpool, 2012 Public Meeting 

Transcript, No. 38 at pp. 103, 129) 

For the August 2012 SNOPR, DOE 

considered these comments, and based 

on these and additional research, 

proposed the items shown below in 

Table 1 as replacements for obsolete or 

nearly obsolete items. 77 FR 49064, 

49065 (Aug. 15, 2012).

Fleischmann’s Original stick margarine. 

Coffee ................................... Folgers, Decaffeinated Drip Grind .................................. Folgers Classic Decaf. 

AHAM, BSH, Samsung, and 

Whirlpool support the proposed 

replacement items for the flatware, 

serving pieces, and food items, 

including the margarine and coffee. 

(AHAM, No. 35 at pp. 2–3; BSH, No. 36 

at p. 2; Samsung, No. 33 at p. 1; 

Whirlpool, No. 32 at p. 1) Therefore, 

DOE adopts these replacement flatware, 

serving pieces, and food items in the 

amendments to appendix C procedure 

in today’s final rule. DOE also includes 

these replacement items in the new 

dishwasher test procedure at appendix 

C1. 

For the dishware replacements, 

AHAM, BSH, Samsung, and Whirlpool 

noted that, although the primary cups 

and saucers specified in the test 

procedure are obsolete, the alternate 

Arzberg items specified are still 

available, albeit with new product 

numbers. The alternate cup, Arzberg 

product number 3824732100, currently 

specified in the dishwasher test 

procedure is now designated as product 

number 1382 00001 4732. The alternate 

saucer, Arzberg product number 

3824731100, currently specified in the 

dishwasher test procedure is now 

designated as product number 1382 

00001 4731. Because the shapes of 

DOE’s proposed replacement cup and 

saucer are different than for the existing 

alternate Arzberg cup saucer and it is 

not known how these differences could 

affect the test results, these commenters 

recommend not adopting DOE’s 

proposal for the cup and saucer. Instead, 

they suggest that DOE designate the 

current alternate Arzberg cup saucer, 

identified by their new product 

numbers, as the primary items and not 

specify alternates. AHAM, BSH, 

Samsung, and Whirlpool further 

commented that DOE’s proposed 

replacement cup and saucer could 

potentially be acceptable alternates, but 

manufacturers would first need to assess 

the impacts of such variables as the 

weight of the items and the ability of 

various rack designs to accommodate 

them. These commenters stated that it 

would be ideal for at least one option for 

the cup and saucer to be sourced from 

within the United States in order to 

minimize burden. (AHAM, No. 35 at pp. 

3–4; BSH, No. 36 at p. 2; Samsung, No. 

33 at p. 1; Whirlpool, No. 32 at p. 1) 

DOE has ascertained that the alternate 

cup and saucer currently specified in 

the DOE test procedure are available for 

purchase at this time under the different 

item numbers identified by commenters. 

Therefore, for consistency in the 

dishwasher test results, DOE amends 

the dishwasher test procedure in today’s 

final rule to specify the current alternate 

Arzberg cup and saucer by their new 

product numbers as the alternate test 

load items. DOE reconsidered its 

proposal to eliminate the specifications 

for the obsolete Corning Comcor/Corelle 

cup and saucer, and instead retains 

these as the primary test load items so 

that manufacturers and testing 

laboratories may continue to use items 

they may already possess. DOE also 

includes these replacement item 

specifications in the new dishwasher 

test procedure at appendix C1. If DOE 

receives additional information 

regarding dishwasher energy and water 

consumption using the Arzberg 

replacement cup and saucer proposed in 

the August 2012 SNOPR, or other 

alternatives suggested by interested 

parties, DOE may consider updating the 

test procedure at that time so that 

additional options for the cup and 

saucer are available to manufacturers 

and testing laboratories. 

For the bread and butter plate, 

AHAM, BSH, Samsung, and Whirlpool 

agreed that the existing Corning 

Comcor/Corelle test item be retained. In 

addition, these commenters agreed with 

the proposed Arzberg replacement item, 

product number 2000 00001 0217 1, as 

an alternate item, but noted that it may 

actually be the redesignated product 

number for the existing Arzberg 

alternate bread and butter plate, product 

number 8500217100. These commenters 

recommend that DOE list both product 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65969 

numbers as alternates in the dishwasher 

test procedure so that testing can 

continue until it is verified whether the 

products are the same. (AHAM, No. 35 

at p. 5; BSH, No. 36 at p. 2; Samsung, 

No. 33 at p. 1; Whirlpool, No. 32 at p. 

1) 

DOE agrees with that the approach 

will minimize impact on manufacturers 

and testing laboratories, and adopts in 

today’s final rule specifications for the 

two Arzberg bread and butter plate 

product numbers as allowable alternate 

test load items in appendix C and 

appendix C1. 

For the fruit bowl, AHAM, BSH, 

Samsung, and Whirlpool agreed with 

DOE’s proposal to retain the existing 

primary Corning Comcor/Corelle 

specification but objected to DOE’s 

proposed Arzberg additional alternate 

specification. The commenters stated 

that the additional replacement fruit 

bowl is significantly larger than the 

existing fruit bowl, so there could be an 

impact on measured energy use due to 

the weight difference and ability for the 

bowl to fit into racks. However, the 

commenters did not provide a 

suggestion for a recommended 

replacement for the alternate fruit bowl. 

(AHAM, No. 35 at p. 5; BSH, No. 36 at 

p. 2; Samsung, No. 33 at p. 1; Whirlpool, 

No. 32 at p. 1) 

DOE acknowledges that the impact of 

a fruit bowl that is larger than the item 

currently specified in the dishwasher 

test procedure is not known. Therefore, 

for consistency in the dishwasher test 

results, DOE does not adopt the 

proposed Arzberg replacement fruit 

bowl as an additional alternate test load 

item in today’s final rule. DOE also 

reconsidered its proposal to eliminate 

the specifications for the obsolete 

Arzberg fruit bowl currently specified as 

the alternate item, and instead retains 

this product as an alternate test load 

item in both appendix C and appendix 

C1 so that manufacturers and testing 

laboratories may continue to use items 

they may already possess. If DOE 

receives additional information 

regarding dishwasher energy and water 

consumption while using the Arzberg 

replacement fruit bowl proposed in the 

August 2012 SNOPR, or another 

alternative suggested by interested 

parties, DOE may consider updating the 

test procedure at that time so that 

additional options for the fruit bowl are 

available to manufacturers and testing 

laboratories. 

In response to the May 2012 SNOPR, 

DOE also received comments that DOE 

should clarify in the dishwasher test 

procedure the length of time that soils 

may sit or be stored before they are 

applied to the dishware. AHAM, BSH, 

and Whirlpool stated that potatoes will 

get stiffer the longer they sit, and 

proposed that prepared potatoes should 

be used within 30 minutes of 

preparation. AHAM and Whirlpool also 

noted that oatmeal settles and thus 

proposed that it should be prepared and 

applied as specified in both ANSI/ 

AHAM DW–1–1992 and ANSI/AHAM 

DW–1–2010; i.e., the oatmeal should 

stand for 1 minute after preparation and 

then be used immediately. Whirlpool 

noted that the length of time that the 

prepared oatmeal sits could cause 

variability in the test procedure. AHAM, 

BSH, and Whirlpool additionally 

recommended that the reconstituted 

milk should be allowed to be stored for 

use over the course of a day, and that 

the prepared one-pound packages of 

beef be allowed to be stored in a freezer 

for up to 6 months to minimize 

variability in the test procedure. 

(AHAM, No. 27 at pp. 8–9; BSH, No. 28 

at p. 6; Whirlpool, No. 26 at p. 1; 

Whirlpool, 2012 Public Meeting 

Transcript, No. 38 at p. 128) 

In the August 2012 SNOPR, DOE 

proposed to amend the dishwasher test 

procedure to require the potatoes to be 

used within 30 minutes of preparation 

and the reconstituted milk be allowed to 

be stored for use over the course of 1 

day, as recommended by commenters. 

DOE’s proposal also included 

provisions for reconstituting the milk. 

DOE additionally proposed to adopt the 

commenters’ recommendation that the 

1-pound packages of ground beef shall 

be stored frozen for no more than 6 

months. DOE determined that the 

instructions contained within the 

referenced sections of both versions of 

ANSI/AHAM DW–1 pertaining to soil 

preparation and application, which are 

or were proposed to be referenced in 

appendix C, are sufficiently clear in 

requiring the prepared oatmeal to sit no 

longer than 1 minute before using. 

Therefore, DOE did not propose any 

clarifications in the August 2012 

SNOPR for the oatmeal preparation. 77 

FR 49064, 49067 (Aug. 15, 2012). 

AHAM, BSH, Samsung, and 

Whirlpool support DOE’s proposed 

clarifications to the soil preparation and 

storage requirements for potatoes, 

reconstituted milk, and ground beef, 

even though these commenters added 

that manufacturer’s instructions for 

reconstituting the milk could change. 

The commenters also reiterated their 

recommendation that the dishwasher 

test procedure specifically require that 

the oatmeal be prepared and used 

consistent with ANSI/AHAM DW–1– 

1992 and 2009. (AHAM, No. 35 at p. 9; 

BSH, No. 36 at p. 3; Samsung, No. 33 

at p. 1; Whirlpool, No. 32 at p. 1) Viking 

commented that it was aware of outside 

laboratories that do not put water into 

the milk formulation directly and 

measure dry milk into the oatmeal 

mixture. (Viking, 2012 Public Meeting 

Transcript, No. 38 at p. 133) 

For the reasons stated above, and 

consideration of comments expressing 

support, DOE is revising the soil 

preparation and storage provisions for 

potatoes, reconstituted milk, and ground 

beef for the new dishwasher test 

procedure in today’s final rule as 

proposed in the August 2012 SNOPR. 

DOE also clarifies in appendix C1 that 

the nonfat dry milk shall be 

reconstituted with water before mixing 

with the oatmeal and potatoes. DOE 

notes that the referenced section 5.5 of 

ANSI/AHAM DW–1–2010 pertaining to 

soil preparation explicitly requires that 

the oatmeal mixture be allowed to stand 

for 1 minute after mixing, then used 

immediately. Thus the instructions the 

commenters seek regarding the use of 

the oatmeal mixture are incorporated by 

reference in today’s new dishwasher test 

procedure without requiring additional 

clarification. 

AHAM commented that there have 

been some questions about the use of a 

brush versus a spatula for soiling the 

dishes because ANSI/AHAM DW–1– 

1992 references utensils, but does not 

provide specific details beyond the 

order of the soil application. (AHAM, 

2012 Public Meeting Transcript, No. 38 

at p. 127) In today’s final rule, DOE 

updates the industry test method in 

appendix C1 from the previous ANSI/ 

AHAM DW–1–1992 to ANSI/AHAM 

DW–1–2010. DOE notes that the newer 

version of this standard includes 

clarification as to which soils should be 

spread with a spatula or brush. 

BSH and Whirlpool commented that 

DOE should harmonize these changes 

with the Canadian test method because 

Canada may have different 

interpretations than DOE. (BSH, 2012 

Public Meeting Transcript, No. 38 at p. 

107; Whirlpool, 2012 Public Meeting 

Transcript, No. 38 at p. 107) 

DOE is aware of the Canadian test 

procedure, which is similar to the DOE 

test procedure in appendix C. To DOE’s 

knowledge, the proposed substitutions 

and soiling times represent an industry 

consensus on these issues, and therefore 

are appropriate additions to the DOE 

test procedure regardless of the 

Canadian interpretation. Additionally, 

the substitute materials available in the 

United States may differ from those 

available in Canada. As a result, DOE 

has included the proposed substitutions 

and soiling times in today’s 

amendments.

10. Rack Position and Loading 

DOE received comments in response 

to the May 2012 SNOPR which 

indicated that the rack position and 

loading pattern for the test load should 

be specified in the dishwasher test 

procedure. AHAM, BSH, and Whirlpool 

stated that the position of the upper rack 

can affect water pressure during a test, 

which BSH and Whirlpool felt could 

influence the rate at which food soils 

fall off the test load and the turbidity 

sensor decisions. AHAM, BSH, and 

Whirlpool recommended that for the 

energy test, the upper rack should be in 

the position recommended by the 

manufacturer, or, in the absence of such 

a recommendation, in the as-shipped 

position to reduce potential test 

variation. (AHAM, No. 27 at p. 11; 

AHAM, 2012 Public Meeting Transcript; 

No. 38 at pp. 141–142; BSH, No. 28 at 

p. 9; BSH, 2012 Public Meeting 

Transcript; No. 38 at pp. 143–144; 

Whirlpool, No. 26 at p. 1; Whirlpool, 

2012 Public Meeting Transcript, No. 38 

at p. 145) Intertek stated that it tests 

dishwashers with the rack in the asshipped position, while UL commented 

that it tests according to the 

manufacturer instructions. (Intertek, 

2012 Public Meeting Transcript, No. 38 

at p. 146; UL, 2012 Public Meeting 

Transcript, No. 38 at p. 151) According 

to BSH, rack position varies from 

product-to-product. Different platforms 

may have the same as-shipped position 

for the racks, yet have different 

manufacturer recommendations in the 

user manuals. (BSH, 2012 Public 

Meeting Transcript, No. 38 at p. 144) 

Furthermore, AHAM stated that the asshipped position of the rack for a 

particular model may not always be the 

same. (AHAM, 2012 Public Meeting 

Transcript, No. 38 at p. 143) 

AHAM, BSH, and Whirlpool 

commented that it is difficult to 

standardize loading patterns due to 

varying rack designs. These commenters 

stated DOE should require a loading 

pattern according to the manufacturer’s 

recommendation. The commenters 

further stated that the unsoiled dishes 

should be loaded first to settle the 

loading arrangement, and then the 

appropriate number of unsoiled dishes 

should be replaced with soiled ones in 

an alternating pattern, avoiding placing 

all soiled dishes in one grouped area or 

in the corners of the racks. AHAM, BSH, 

and Whirlpool pointed out that this 

method is similar to what DOE 

proposed in its first draft performance 

test procedure for ENERGY STAR. 

(AHAM, No. 27 at p. 9; BSH, No. 28 at 

p. 7; Whirlpool, No. 26 at p. 1) 

In the August 2012 SNOPR, DOE 

proposed amendments to the 

dishwasher test procedure that would 

require adjusting the rack position 

according to the manufacturer 

recommendations and loading the 

soiled dishes according to section 5.8 of 

ANSI/AHAM DW–1–2010, which 

specifies loading the dishware in 

accordance with manufacturer’s 

recommendation, following the loading 

pattern provided in the manufacturer’s 

use and care guide, without nesting the 

dishware or flatware. DOE concluded 

that these proposed amendments would 

improve test repeatability and 

reproducibility. 77 FR 49064, 49066–67 

(Aug. 15, 2012). 

AHAM, BSH, Samsung, and 

Whirlpool supported the requirement 

that the rack be positioned according to 

manufacturer recommendations for 

washing a full load of normally soiled 

dishes. But they further recommended 

that DOE specify that, in the absence of 

a manufacturer recommendation 

regarding rack position for the normal 

cycle, the rack shall be positioned in the 

as-shipped position. (AHAM, No. 35 at 

p. 8; BSH, No. 36 at p. 3; Samsung, No. 

33 at p. 1; Whirlpool, No. 32 at p. 1) 

DOE notes that, although AHAM had 

also indicated in response to the May 

2012 SNOPR that the as-shipped 

position may vary for a particular 

model, it is likely that in such instances, 

manufacturers would provide 

instructions as to the appropriate rack 

placement during operation. 

Furthermore, it is likely that a 

dishwasher that does not provide 

instructions regarding rack position 

would be shipped with the rack in a 

position suitable for washing a full load 

of normally soiled dishes. Therefore, to 

provide clarity to testing laboratories 

regarding rack position for both 

situations, DOE adopts in today’s final 

rule for appendix C1 the instructions to 

install the dishwasher with the rack 

positioned according to manufacturer 

instructions for washing a full load of 

normally soiled dishes, and that in the 

absence of such instructions, the rack 

shall be maintained in the as-shipped 

position. 

AHAM, BSH, Samsung, and 

Whirlpool reiterated that dish loading is 

a potential source for variation, and that 

it is difficult to achieve standardization 

of loading patterns because rack designs 

vary. The commenters also noted that 

DOE did not propose specifications for 

how the soiled items are to be 

distributed when loaded (i.e., all 

positioned together or alternating with 

the unsoiled items.) Thus, AHAM, BSH, 

Samsung, and Whirlpool recommend a 

loading pattern according to the 

manufacturer’s recommended loading 

pattern, with addition specification that 

the unsoiled dishes be loaded first to 

settle the loading arrangement, and then 

the appropriate number of unsoiled 

dishes be replaced with soiled ones 

with soiled and unsoiled dishes 

alternating. The commenters would 

further recommend that testers should 

avoid placing all soiled dishes in one 

grouped area or in the corners of the 

racks. AHAM, BSH, Samsung, and 

Whirlpool again noted these 

instructions would be similar to those 

proposed in the first draft ENERGY 

STAR test method for dishwasher 

performance, and they encouraged DOE 

to harmonize the loading requirements 

in appendix C and the future ENERGY 

STAR test method. (AHAM, No. 35 at p. 

10; BSH, No. 36 at p. 3; Samsung, No. 

33 at p. 1; Whirlpool, No. 31 at p. 1) 

DOE is not aware of, nor did 

commenters provide, data indicating 

whether the loading arrangement of 

dishes may impact the measured energy 

and water consumption of a particular 

dishwasher, but notes that the loading 

requirements proposed in the August 

2012 SNOPR, which reference section 

5.8 of ANSI/AHAM DW–1–2010 and 

accordingly its requirement to follow 

the manufacturer’s instructions, do not 

generally preclude testing using an 

alternating loading pattern of soiled and 

clean dishware. However, some 

manufacturer’s instructions could 

conflict with specific requirements for 

the location of the soiled items. For 

example, the manufacturer may 

recommend that the most heavily soiled 

items be placed in a certain location on 

the rack, which would conflict with the 

instructions to alternate soiled and 

clean items. For these reasons, DOE is 

not adding in today’s final rule any 

additional loading instructions in the 

dishwasher test procedure beyond those 

specified in section 5.8 of ANSI/AHAM 

DW–1–2010. 

11. Rinse Aid Container 

The dishwasher test procedure 

precludes the use of rinse aid during 

testing, including preconditioning. 

However, AHAM, BSH, and Whirlpool 

commented in response to the May 2012 

SNOPR that some third-party 

laboratories fill the rinse aid container 

before the starting the energy test cycle, 

presumably to prevent an indicator light 

from turning on during the test. These 

commenters believe that DOE should 

clarify that the rinse aid container 

should not be filled with water. 

According to BSH, the added water 

creates a thermal mass that must be 

heated when the dishwasher is 

operated, which would result in higher 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65971 

energy use. AHAM, BSH, and Whirlpool 

stated that if the indicator light does 

turn on, its energy use should be 

measured. (AHAM, No. 27 at p. 11; 

AHAM, 2012 Public Meeting Transcript, 

No. 38 at pp. 135–136; BSH, No. 28 at 

p. 8; BSH, 2012 Public Meeting 

Transcript, No. 38 at p. 136; Whirlpool, 

No. 26 at p. 1) 

DOE agreed with commenters, and for 

reasons of consistency in testing, 

proposed in the August 2012 SNOPR 

amendments to the dishwasher test 

procedure that would clarify that the 

rinse aid container should not be filled 

with water for energy testing. 77 FR 

49064, 49067 (Aug. 15, 2012). AHAM, 

BSH, Samsung, and Whirlpool agreed 

with this proposal. (AHAM, No. 35 at p. 

8; BSH, No. 36 at p. 3; Samsung, No. 33 

at p. 1; Whirlpool, No. 32 at p. 1) DOE 

adopts in today’s final rule this 

provision for the new dishwasher test 

procedure to ensure reproducibility of 

results. 

12. Technical Corrections 

In the May 2012 SNOPR, DOE noted 

that in sections 5.4.1 and 5.4.2 of the 

current dishwasher test procedure, 

water energy consumption is calculated 

as specified for both non-soil-sensing 

and soil-sensing dishwashers using 

electrically heated water ‘‘[f]or the 

normal and truncated normal test 

cycle.’’ Because the normal and 

truncated normal test cycles do not 

apply to soil-sensing dishwashers, DOE 

proposed to remove this qualification in 

newly designated sections 5.5.1.1 and 

5.5.2.1. Similarly, in sections 5.5.1 and 

5.5.2 of the current dishwasher test 

procedure, water energy consumption is 

calculated as specified for both non-soilsensing and soil-sensing dishwashers 

using gas-heated or oil-heated water 

‘‘[f]or each test cycle.’’ Because for soilsensing dishwashers the calculation is 

applied to a single weighted-average 

water consumption measured over the 

sensor heavy response, sensor medium 

response, and sensor light response 

cycles, this qualification may cause 

confusion. Therefore, DOE proposed to 

remove this qualification in newly 

designated sections 5.6.1.1 and 5.6.2.1. 

DOE also proposed to correct references 

to the water consumption values used in 

the calculation of water energy 

consumption in these sections of the 

dishwasher test procedure, so that 

separate references are provided for 

non-soil-sensing and soil-sensing 

dishwashers. 77 FR 31444, 31454 (May 

25, 2012). 

In addition, DOE stated in the May 

2012 SNOPR that, due to a transcription 

error in publication, the September 2011 

SNOPR erroneously specified in the 

regulatory text for the proposed 

dishwasher test procedure amendments 

the calculation of estimated annual 

operating cost for dishwashers having a 

truncated normal cycle which operate at 

50 °F inlet water temperature. 

Specifically, the calculation proposed in 

10 CFR 430.23(c)(1)(i)(B) contained 

extraneous variables ‘‘B’’ and ‘‘V.’’ DOE 

proposed, therefore, in the May 2012 

SNOPR to remove these extraneous 

variables to correct the calculation. 77 

FR 31444, 31455 (May 25, 2012). DOE 

maintained these proposals in the 

August 2012 SNOPR. 

AHAM, BSH, and Whirlpool 

commented that they did not oppose 

these two technical corrections to the 

dishwasher test procedure. (AHAM, No. 

27 at p. 13; BSH, No. 28 at p. 10; 

Whirlpool, No. 26 at p. 1) For the 

reasons explained above, DOE adopts in 

today’s final rule the corrections to 

water energy consumption provisions in 

both the new and currently applicable 

dishwasher test procedures. DOE also 

adopts the corrected calculation 

described above in its amendments to 

10 CFR 430.23(c). 

Whirlpool commented that DOE 

should revise its proposal in the May 

2012 SNOPR for section 4.1.2 in the 

dishwasher test procedure to specify 

that VWSavg is defined as the average of 

VWS,1 and VWS,2. (Whirlpool, No. 26 at 

p. 1) These variables represent the water 

consumption measured during test 

cycles performed to determine the water 

use associated with water softener 

regeneration. In the initial portion of the 

test, two test cycles are run, and the 

water consumption measured for each 

(VWS,1 and VWS,2) are compared. If the 

difference in water consumption 

between the two cycles is greater than 

10 percent, the cycle in which the larger 

water use occurred is deemed to contain 

a water softener regeneration event. The 

water consumption associated with a 

cycle containing a water softener 

regeneration event (VWSmax) is, under 

these conditions, the larger of VWS,1 and 

VWS,2. The smaller of VWS,1 and VWS,2

would be deemed to represent a typical 

non-water softener regeneration cycle, 

denoted by VWSavg. DOE proposed this 

terminology because, if a water softener 

regeneration event doesn’t occur in the 

first two test cycles, additional cycles 

are run, with the water consumption for 

each new cycle being compared to the 

average of water consumptions for the 

previous cycles. Averaging the water 

consumptions for the non-water softener 

regeneration cycles would decrease 

variation in the test procedure results. 

Because VWSavg represents a typical nonwater softener regeneration cycle, not a 

numerical average of VWS,1 and VWS,2, 

DOE did not alter its proposal for the 

August 2012 SNOPR as Whirlpool 

suggested, nor is it adopting such a 

revision to the provisions in the new 

dishwasher test procedure established 

in today’s final rule because the water 

consumption for water softener 

regeneration shall be a value reported by 

the manufacturer. 

In the May 2012 SNOPR, DOE 

inadvertently proposed in section 4.4.2 

of the dishwasher test procedure 

language that refers to section 1.11 of 

the test procedure. DOE corrected that 

proposal in the August 2012 SNOPR to 

properly refer to section 1.13. DOE 

includes section 4.2.2 of appendix C1 in 

today’s final rule according to the 

August 2012 SNOPR. 

I. Incorporation by Reference of an 

Updated AHAM Dehumidifier Test 

Procedure 

In the May 2012 SNOPR, DOE 

proposed updating the dehumidifier test 

procedure to clarify which version of 

the AHAM test method ‘‘Dehumidifiers’’ 

(DH–1) should be used for testing. DOE 

evaluated both DH–1–1992 and DH–1– 

2008, and concluded that both versions 

would produce comparable results for 

the DOE dehumidifier test procedure. 

However, DOE proposed referencing the 

newer version, DH–1–2008, for both the 

capacity and EF measurements because 

it provides additional clarity and 

specificity that may improve test 

accuracy, repeatability, and 

reproducibility. DOE also proposed 

removing the reference to the ENERGY 

STAR qualification criteria for 

determining EF, given that the EF 

methodology is included in DH–1–2008. 

77 FR 31444, 31453–54 (May 25, 2012). 

DOE maintained this proposal for the 

August 2012 SNOPR. 

AHAM, BSH, and Whirlpool support 

DOE’s proposal to incorporate by 

reference ANSI/AHAM DH–1–2008 for 

the measurement of capacity and EF, 

and the calculation of IEF, in its 

dehumidifier test procedure. The 

commenters stated that clarity and 

consistency for regulated parties is 

critical so that all regulated and other 

parties (e.g., third-party laboratories, 

DOE, EPA) are testing per the same test 

procedure; therefore, they believe it is 

important that DOE clarify which 

version of DH–1 it intends to reference 

in its test procedure. AHAM, BSH, and 

Whirlpool commented that, to their 

knowledge, there is no difference in the 

measured energy between versions of 

DH–1, but each version contains 

important technical improvements and 

clarifications, making the most current 

version of the standard the best one to 

reference. (AHAM, No. 27 at p. 13; BSH, 


srobinson on DSK4SPTVN1PROD with 
65972 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

No. 28 at p. 10; Whirlpool, No. 26 at p. 

1) 

In consideration of this support and 

for the reasons previously stated, DOE 

incorporates by reference ANSI/AHAM 

DH–1–2008 in appendix X1 as the test 

method for determining capacity and 

EF. DOE also does not include in 

appendix X1 the previous reference to 

the ENERGY STAR qualification criteria 

for determining EF. 

J. Removal of Obsolete Measures of Gas 

Pilot Light Energy Consumption in the 

Conventional Cooking Products Test 

Procedure and of Energy Factor 

Calculations for Dishwashers 

The energy conservation standards for 

cooking products require that gas 

cooking products manufactured on or 

after April 9, 2012, shall not be 

equipped with a constant-burning pilot 

light. 10 CFR 430.32(j). In the May 2012 

SNOPR, DOE proposed removing the 

provisions for measuring the energy 

consumption of constant-burning pilot 

lights from the conventional cooking 

products test procedures. 77 FR 31444, 

31455 (May 25, 2012). 

AHAM, BSH, and Whirlpool support 

removing the constant-burning pilot 

light provisions from the conventional 

cooking products test procedures. 

(AHAM, No. 27 at p. 13; BSH, No. 28 

at p. 11; Whirlpool, No. 26 at pp. 1, 5) 

Given this support and the obsolescence 

of constant-burning pilot lights, today’s 

amendments remove the standing pilot 

light provisions from the test procedures 

for conventional cooking products. 

Specifically, today’s final rule removes 

the following existing sections in 10 

CFR part 430, subpart B, appendix I: 

• Section 2.9.2.2 (‘‘Flow meter’’); 

• Section 3.1.1.2 (‘‘Continuously 

burning pilot lights of a conventional 

gas oven’’); 

• Section 3.1.2.1 (‘‘Continuously 

burning pilot lights of a conventional 

gas cooking top’’); 

• Section 3.2.1.3 (‘‘Gas consumption 

of continuously burning pilot lights’’ 

[for conventional gas ovens]); 

• Section 3.2.2.1 (‘‘Gas consumption 

of continuously burning pilot lights’’ 

[for conventional gas cooking tops]); 

• Section 3.3.7 (recording the gas 

flow rate or gas consumption and 

elapsed time for a continuously burning 

pilot light of a conventional gas oven); 

• Section 3.3.10 (recording the gas 

flow rate or gas consumption and 

elapsed time for a continuously burning 

pilot light of a conventional gas cooking 

top); 

• Section 4.1.2.2 (‘‘Annual energy 

consumption of any continuously 

burning pilot lights’’ [for conventional 

gas ovens]); and 

• Section 4.2.2.2.2 (‘‘Annual energy 

consumption of any continuously 

burning gas pilots’’ [for conventional gas 

cooking tops]). 

Today’s final rule also modifies (and 

renumbers where appropriate) the 

following existing sections in appendix 

I to eliminate the measures of energy 

use relating to gas pilot lights: 

• Section 1.7 (‘‘Normal nonoperating 

temperature’’); 

• Section 1.14 (‘‘Symbol usage’’); 

• Section 2.9.2.1 (‘‘Positive 

displacement meters’’); 

• Section 3.1.1 (‘‘Conventional 

oven’’); 

• Section 3.1.1.1 (‘‘Self-cleaning 

operation of a conventional oven’’); 

• Section 3.1.2 (‘‘Conventional 

cooking top’’); 

• Section 4.1.2.5.2 (‘‘Conventional 

gas oven energy consumption’’); 

• Section 4.1.2.6.2 (‘‘Conventional 

gas oven energy consumption’’ [for 

multiple conventional gas ovens’’]); 

• Section 4.2.1.2 (‘‘Gas surface unit 

cooking efficiency’’); and 

• Section 4.2.2.2.3 (‘‘Total annual 

energy consumption of a conventional 

gas cooking top’’). 

In the May 2012 SNOPR, DOE also 

proposed to eliminate the calculation of 

energy factor for dishwashers in 10 CFR 

430.23 because this metric is no longer 

used in DOE’s energy conservation 

standards for dishwashers or to make 

representations of energy efficiency. 77 

FR 31444, 31455 (May 25, 2012). DOE 

did not receive any comments on this 

proposal, and amends 10 CFR 430.23 in 

today’s final rule to eliminate the energy 

factor calculation. 

K. Compliance With Other EPCA 

Requirements 

1. Test Burden 

EPCA requires that any test 

procedures prescribed or amended 

under this section be reasonably 

designed to produce test results which 

measure energy efficiency, energy use or 

estimated annual operating cost of a 

covered product during a representative 

average use cycle or period of use and 

shall not be unduly burdensome to 

conduct. (42 U.S.C. 6293(b)(3)) 

In the December 2010 NOPR, DOE 

noted that the proposed amendments to 

the residential dishwasher, 

dehumidifier, and conventional cooking 

products test procedures would 

incorporate a test standard that is 

accepted internationally for measuring 

power consumption in standby mode 

and off mode (IEC Standard 62301). 

DOE analyzed the available versions of 

IEC Standard 62301 at that time—IEC 

Standard 62301 (First Edition), IEC 

Standard 62301 (CDV), and IEC 

Standard 62301 (FDIS)—and 

determined that the proposed 

amendments to the residential 

dishwashers, dehumidifiers, and 

conventional cooking products test 

procedures would produce standby 

mode and off mode average power 

consumption measurements 

representative of an average use cycle. 

DOE also determined that the test 

methods and equipment that the 

amendments would require for 

measuring standby mode and off mode 

power in these products would not be 

substantially different from the test 

methods and equipment required in the 

current DOE tests. Thus, DOE 

tentatively concluded that the proposed 

test procedure amendments would not 

require manufacturers to make 

significant investments in test facilities 

and new equipment. In sum, DOE 

tentatively concluded in the December 

2010 NOPR that the amended test 

procedures would produce test results 

that measure the standby mode and off 

mode power consumption during 

representative use, and that the test 

procedures would not be unduly 

burdensome to conduct. 75 FR 75290, 

75316 (Dec. 2, 2010). 

The September 2011 SNOPR 

proposed amendments to the DOE test 

procedures based on an updated version 

of IEC Standard 62301, IEC Standard 

62301 (Second Edition), which has been 

the subject of significant review and 

input from interested parties and, thus, 

continues to be an internationally 

accepted test standard for measuring 

standby mode and off mode power 

consumption. As discussed in the 

September 2011 SNOPR, the provisions 

of IEC Standard 62301 (Second Edition) 

that DOE proposed to incorporate by 

reference provide a means to measure 

power consumption with greater 

accuracy and repeatability than the 

provisions from IEC Standard 62301 

(First Edition) that were originally 

proposed in the December 2010 NOPR. 

For this reason, DOE tentatively 

concluded that the amendments 

proposed in the September 2011 SNOPR 

would also provide measurements 

representative of average consumer use 

of the product under test. DOE further 

determined that these new provisions in 

the applicable sections of IEC Standard 

62301 (Second Edition) would improve 

test results without undue testing 

burden. DOE acknowledged in the 

September 2011 SNOPR that certain 

methods from IEC Standard 62301 

(Second Edition) may increase test 

duration, but where such an increase 

was deemed excessive (i.e., for products 


srobinson on DSK4SPTVN1PROD with 
Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 65973 

18Certification requirements for industrial 

equipment are also included in these regulations. 

with clocks that can vary in power 

consumption as a function of time 

displayed), DOE retained the method 

previously proposed to mitigate test 

burden. The potential for increased test 

burden in other power consumption 

measurements is offset by more 

reasonable requirements for testing 

equipment, while maintaining 

measurement accuracy deemed 

acceptable and practical by voting 

members for IEC Standard 62301 

(Second Edition). Thus, DOE tentatively 

concluded that the amended test 

procedures proposed in the September 

2011 SNOPR would produce test results 

that measure the standby mode and off 

mode power consumption during 

representative use, and that the test 

procedures would not be unduly 

burdensome to conduct. 76 FR 58346, 

58354 (Sep. 20, 2011). 

In the May 2012 SNOPR, DOE 

proposed to measure energy use in fanonly mode for dishwashers and 

conventional cooking products as a 

continuation of the active mode cycle, 

which would require more stringent 

specifications for the watt-hour meters 

than currently specified in the 

dishwasher and conventional cooking 

products test procedures. By not 

requiring a separate cycle to be run, the 

proposed approach would minimize test 

burden associated with the 

measurement of fan-only mode. The 

May 2012 SNOPR also proposed 

amendments to incorporate the energy 

and water use associated with 

dishwasher water softener regeneration. 

Manufacturers would need to run up to 

an additional ten cycles to ensure that 

a regeneration process is captured. DOE 

based this proposal on the information 

supplied by manufacturers that, on 

average, water-softening dishwashers 

regenerate approximately once every six 

cycles. To minimize test burden, 

particularly for soil-sensing 

dishwashers, DOE proposed in the May 

2012 SNOPR that these cycles would be 

run with no test load, since DOE 

believes that a substantial part of the 

burden for the existing test procedure is 

incurred by the preparation and 

application of soils to the dishware. 77 

FR 31444, 31447–51 (May 25, 2012). 

The May 2012 SNOPR’s proposal to 

reference AHAM DH–1–2008 in the 

dehumidifier test procedure would, 

according to DOE’s estimates, require 

more accurate measurement equipment 

that would cost approximately $500. 

DOE also noted in the May 2012 SNOPR 

that the proposed test room 

requirements could require the use of a 

larger test chamber than is specified 

under the current test procedure, and 

could also require different air handling 

equipment. DOE noted that many test 

laboratories may already be using 

AHAM DH–1–2008 and, thus, may 

already meet these requirements. In 

addition, for those laboratories that are 

recording data manually, the more 

frequent data recording events in DOE’s 

proposal could result in three times the 

data recording events than are currently 

required. Because only four parameters 

are recorded for each event, however, 

DOE estimated in the May 2012 SNOPR 

that the total increase in operator time 

would be less than 1 hour. 77 FR 31444, 

31453–54 (May 25, 2012). 

In the August 2012 SNOPR, DOE 

noted that the replacement items 

proposed were intended to be 

inexpensive, representative of 

commonly-found items, and in some 

cases already used by manufacturers in 

testing dishwashers. In addition, DOE 

proposed a definition of normal cycle 

for dishwashers supported by 

manufacturers because it will lead to 

consistent, representative results. The 

updated industry test method for 

dishwashers was also supported by 

manufactures because it will lead to, 

among other things, reduced test 

variation, as would the proposals for 

consistent preparation time for the soils 

used in the test procedure, the 

positioning of the dishwasher rack 

during testing, the method of loading, 

the tighter tolerances on ambient 

temperature, the added specifications 

for water pressure measurement and 

drain height, and the clarifications for 

the rinse aid container. Finally, DOE 

proposed an alternative method of 

measuring the energy use in fan-only 

mode for dishwashers and cooking 

products that could significantly 

decrease overall testing time. 77 FR 

49064, 49065–67 (Aug. 15, 2012). 

AHAM, BSH, and Whirlpool 

estimated the test burden associated 

with the proposed water softener 

regeneration test method for the 

dishwasher test procedure to be 20 to 30 

additional test hours. (AHAM, No. 27 at 

p. 4; BSH, No. 28 at p. 2; Whirlpool, No. 

26 at p. 1) DOE considered 

manufacturer test burden when it 

evaluated comments on its proposed 

methodology for measuring energy and 

water use due to water softener 

regeneration, and acknowledges that the 

proposal would add burden by requiring 

up to an additional 10 dishwasher 

washing and drying cycles, compared to 

either one or three washing and drying 

cycles and one preconditioning cycle 

currently required in the test procedure. 

As discussed in section III.F.3, DOE is 

not adopting the proposed testing 

methodology in today’s final rule due to 

this burden, Instead, DOE includes in 

the new dishwasher test procedure 

measures of energy and water 

consumption for water softener 

regeneration using manufacturerreported values for the energy and water 

use for each regeneration cycle and the 

number of annual regeneration cycles. 

DOE additionally discusses in section 

IV.B of this notice comments received 

regarding the investments that 

manufacturers may incur due to today’s 

final rule and DOE’s determination that 

they do not represent significant 

burden. Therefore, for the reasons 

discussed above, DOE concludes that 

the new and amended test procedures 

for dishwashers, dehumidifiers, and 

conventional cooking products will 

produce test results that measure the 

active mode, standby mode, and off 

mode power consumption during 

representative use, and that the test 

procedures will not be unduly 

burdensome to conduct. 

2. Certification Requirements 

As codified at 42 U.S.C. 6299, et seq., 

EPCA authorizes DOE to enforce 

compliance with the energy and water 

conservation standards established for 

covered consumer products. On March 

7, 2011, the Department published a 

final rule in the Federal Register, which 

revised, consolidated, and streamlined 

its existing certification, compliance, 

and enforcement regulations for covered 

consumer products, including 

dishwashers, dehumidifiers, and 

conventional cooking products. 76 FR 

12422.18 The certification regulations 

are codified at 10 CFR 429.19 

(dishwashers), 10 CFR 429.23 

(conventional cooking tops, 

conventional ovens, microwave ovens), 

and 10 CFR 429.36 (dehumidifiers). 

The certification requirements for 

each of the products covered in today’s 

final rule consist of a sampling plan for 

selection of units for testing and 

requirements for certification reports. 

AHAM commented that no revisions 

would be required for current standards 

for dehumidifiers and conventional 

cooking products, so that no changes are 

necessary for the reporting requirements 

for these products. AHAM also 

supported DOE’s proposed changes to 

the sampling plan for dehumidifiers and 

conventional cooking products. (AHAM, 

No. 20 at p. 3) Because the amendments 

and new provisions adopted for 

dehumidifiers and conventional cooking 

products test procedures will not revise 

the current energy conservation 

standards, DOE is not proposing any 

amendments to the certification 


srobinson on DSK4SPTVN1PROD with 
65974 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

reporting requirements for these 

products. However, because DOE in 

today’s final rule introduces a new 

metric (IEF) for both conventional 

cooking products and dehumidifiers, 

DOE additionally amends provisions in 

the sampling plan at 10 CFR 429.23 and 

10 CFR 429.36 that include IEF along 

with the existing measure of EF. 

AHAM stated that the measured 

energy use for dishwashers will be 

affected by the amendments to the 

dishwasher test procedure. For example, 

cycle finished mode energy use is not 

currently measured, but will required to 

be included under the amended test 

procedure. AHAM commented that DOE 

should amend the reporting 

requirements to account for the change. 

(AHAM, No. 20 at p. 3) No such 

amendments are adopted for residential 

dishwashers in today’s final rule 

because DOE is not adding any new 

energy efficiency metric for these 

products. DOE is, though, amending in 

today’s final rule the reporting 

requirements in 10 CFR 429.19 for 

dishwashers to specify that 

manufacturers submit with their 

certification reports: (1) The cycle 

selected for the energy test; (2) whether 

the cycle selected for the energy test is 

soil-sensing; (3) the options selected for 

the energy test; and (4) whether the 

dishwasher has a built-in water 

softening system, and if yes, the energy 

and water use required for each 

regeneration of the water softening 

system, the number of regeneration 

cycles per year, and data and 

calculations used to derive these values. 

IV. Procedural Issues and Regulatory 

Review 

A. Review Under Executive Order 12866 

The Office of Management and Budget 

has determined that test procedure 

rulemakings do not constitute 

‘‘significant regulatory actions’’ under 

section 3(f) of Executive Order 12866, 

Regulatory Planning and Review, 58 FR 

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

action was not subject to review under 

the Executive Order by the Office of 

Information and Regulatory Affairs 

(OIRA) in the Office of Management and 

Budget (OMB). 

B. Review Under the Regulatory 

Flexibility Act 

The Regulatory Flexibility Act (5 

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

of a regulatory flexibility analysis for 

any rule that by law must be proposed 

for public comment, unless the agency 

certifies that the rule, if promulgated, 

will not have a significant economic 

impact on a substantial number of small 

entities. As required by Executive Order 

13272, ‘‘Proper Consideration of Small 

Entities in Agency Rulemaking,’’ 67 FR 

53461 (Aug. 16, 2002), DOE published 

procedures and policies on February 19, 

2003, to ensure that the potential 

impacts of its rules on small entities are 

properly considered during the DOE 

rulemaking process. 68 FR 7990. DOE 

has made its procedures and policies 

available on the Office of the General 

Counsel’s Web site: www.gc.doe.gov/gc/ 

office-general-counsel 

DOE reviewed today’s final rule under 

the provisions of the Regulatory 

Flexibility Act and the procedures and 

policies published on February 19, 

2003. DOE has concluded that the rule 

would not have a significant impact on 

a substantial number of small entities. 

The factual basis for this certification is 

as follows: 

The Small Business Administration 

(SBA) considers a business entity to be 

small business, if, together with its 

affiliates, it employs less than a 

threshold number of workers specified 

in 13 CFR part 121. These size standards 

and codes are established by the North 

American Industry Classification 

System (NAICS). The threshold number 

for NAICS classification code 335228, 

‘‘Other Major Household Appliance 

Manufacturing,’’ which applies to 

residential dishwasher manufacturers, is 

500 employees. The threshold number 

for NAICS classification code 335221, 

‘‘Household Cooking Appliance 

Manufacturing,’’ which applies to 

manufacturers of residential 

conventional cooking products, is 750 

employees. The threshold number for 

NAICS classification code 335211, 

‘‘Electric Housewares and Household 

Fan Manufacturing,’’ which applies to 

dehumidifier manufacturers, is 750 

employees. 

Most of the manufacturers supplying 

residential dishwashers, dehumidifiers, 

and/or conventional cooking products 

are large multinational corporations. 

DOE surveyed the AHAM member 

directory to identify manufacturers of 

residential dishwashers, dehumidifiers 

and conventional cooking products. 

DOE then consulted publicly-available 

data, purchased company reports from 

vendors such as Dun and Bradstreet, 

and contacted manufacturers, where 

needed, to determine if they meet the 

SBA’s definition of a ‘‘small business 

manufacturing facility’’ and have their 

manufacturing facilities located within 

the United States. Based on this 

analysis, DOE identified no small 

businesses that manufacture 

dishwashers, five small businesses that 

manufacture dehumidifiers, and two 

small businesses that manufacture 

conventional cooking products. 

Today’s final rule amends DOE’s test 

procedures for dishwashers, 

dehumidifiers, and cooking products. 

Because DOE is unaware of any small 

businesses that manufacture 

dishwashers, there are no impacts on 

such manufacturers due to the 

amendments to DOE’s dishwasher test 

procedure. 

Today’s rule amends DOE’s test 

procedures for dehumidifiers and 

conventional cooking products by 

incorporating testing provisions to 

address standby mode and off mode 

energy use in these products, as well as 

cooking products fan-only mode energy 

consumption. The test procedure 

amendments involve measuring power 

input when the product is in standby 

mode or off mode, as well as fan-only 

mode for a conventional cooking 

product. These tests can be conducted 

in the same facilities used for the 

current energy testing of these products, 

so there are no additional facilities costs 

required by this final rule. In addition, 

while the watt-hour meter required for 

these tests might require greater 

accuracy than the watt-hour meter used 

for current energy testing, the 

investment required for a possible 

instrumentation upgrade would likely 

be relatively modest. It is possible that 

the manufacturers, or their testing 

facilities, already have equipment that 

meets the more stringent meter 

requirements, but an Internet search of 

equipment that specifically meets the 

requirements reveals a cost of 

approximately $2,000. 

Whirlpool stated that the equipment 

necessary to meet the requirements of 

IEC Standard 62301 (Second Edition) for 

measuring airflow and harmonics either 

does not exist or does not exist in 

sufficient accuracy or quantity. 

Whirlpool estimated that the cost to its 

company of such equipment would be 

up to $48,000, and that the cost for test 

equipment upgrades for the harmonics 

measurement alone would be $10,000. 

(Whirlpool, No.21 at p. 3; Whirlpool, 

No. 26 at p. 6) Although Whirlpool’s 

estimates are higher than DOE’s, DOE 

recognizes that a large manufacturer 

may require multiple meters to equip its 

testing facilities, and that a small 

business would likely require 

investments in the range of DOE’s 

estimates. 

Today’s final rule also updates the 

industry test method for dehumidifiers 

in new appendix X1. As discussed in 

III.K.1, this update could impose on 

manufacturers a cost for new 

measurement equipment of 

approximately $500, as well as

19Annual revenue estimates based on financial 

reports obtained from Hoover’s Inc., available 

online at www.hoovers.com. 

potentially increasing operator time by 

less than 1 hour over the course of a 24- 

hour test. 

The costs described above are small 

compared to the overall financial 

investment needed to undertake the 

business enterprise of testing consumer 

products which involves facilities, 

qualified staff, and specialized 

equipment. Based on its review of 

industry data,19 DOE estimates that the 

small dehumidifier and cooking product 

businesses have annual revenues of $10 

million to $60 million. 

DOE recognizes that the updated 

reference to the industry dehumidifier 

test method could potentially require 

manufacturers to install a larger test 

chamber and different air handling 

equipment. However, some 

manufacturers may already be using 

ANSI/AHAM DH–1–2008 in certifying 

their products. DOE notes that one of 

the small businesses has products listed 

in AHAM’s current dehumidifier 

certification database, indicating that 

those tests were conducted according to 

DH–1–2008. In addition, AHAM 

selected an independent test laboratory 

to conduct dehumidifier testing and 

verification using DH–1–2008. It is 

likely that testing that this laboratory 

performs for manufacturers to determine 

compliance with energy conservation 

standards would be conducted in the 

same facility. Therefore, DOE concludes 

that small businesses would not be 

likely to require investments in facility 

upgrades due to the new dehumidifier 

test procedure that references DH–1– 

2008. 

Furthermore, DOE adopts in today’s 

final rule amendments that limit the 

duration of the fan-only mode testing for 

conventional ovens and conventional 

ranges to minimize test burden. Under 

today’s final rule, the energy use in fanonly mode is measured for 10 minutes, 

and then extrapolated over the duration 

of the fan-mode. DOE estimates that the 

total time currently required for 

conventional oven testing (or for testing 

the conventional oven portion of a 

range) to be approximately 4 hours for 

products not equipped with the 

capability for forced convection or selfcleaning, with an additional 3 hours 

required for testing forced convection 

and an additional 4 hours required for 

testing self-clean operation. DOE’s 

research did not identify any 

conventional ovens or conventional 

ranges manufactured by either of the 

two small cooking products 

manufacturers that are equipped with 

either forced convection or self-clean 

capability. DOE estimates that fan-only 

mode testing in the absence of such 

features could increase testing time by 

approximately 3 percent. However, 

DOE’s research also suggests that none 

of the conventional ovens and 

conventional ranges manufactured by 

the two small cooking products 

businesses are capable of operation in 

fan-only mode, and therefore it is 

unlikely that these manufacturers would 

be impacted by the fan-only mode 

testing provisions. 

For these reasons, DOE concludes and 

certifies that today’s final rule will not 

have a significant economic impact on 

a substantial number of small entities. 

Accordingly, DOE has not prepared a 

regulatory flexibility analysis for this 

rulemaking. DOE has transmitted the 

certification and supporting statement 

of factual basis to the Chief Counsel for 

Advocacy of the SBA for review under 

5 U.S.C. 605(b). 

C. Review Under the Paperwork 

Reduction Act of 1995 

Manufacturers of residential 

dishwashers, dehumidifiers, and 

conventional cooking products must 

certify to DOE that their products 

comply with any applicable energy 

conservation standards. In certifying 

compliance, manufacturers must test 

their products according to the DOE test 

procedures for residential dishwashers, 

dehumidifiers, and conventional 

cooking products including any 

amendments adopted for those test 

procedures. DOE has established 

regulations for the certification and 

recordkeeping requirements for all 

covered consumer products and 

commercial equipment, including 

residential dishwashers, dehumidifiers, 

and conventional cooking products. (76 

FR 12422 (Mar. 7, 2011). The collectionof-information requirement for the 

certification and recordkeeping is 

subject to review and approval by OMB 

under the Paperwork Reduction Act 

(PRA). This requirement has been 

approved by OMB under OMB control 

number 1910–1400. Public reporting 

burden for the certification is estimated 

to average 20 hours per response, 

including the time for reviewing 

instructions, searching existing data 

sources, gathering and maintaining the 

data needed, and completing and 

reviewing the collection of information. 

Notwithstanding any other provision 

of the law, no person is required to 

respond to, nor shall any person be 

subject to a penalty for failure to comply 

with, a collection of information subject 

to the requirements of the PRA, unless 

that collection of information displays a 

currently valid OMB Control Number. 

D. Review Under the National 

Environmental Policy Act of 1969 

In this final rule, DOE amends its test 

procedure for 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 rule amends an 

existing rule without affecting the 

amount, quality or distribution of 

energy usage, and, therefore, will not 

result in any environmental impacts. 

Thus, this rulemaking is covered by 

Categorical Exclusion A5 under 10 CFR 

part 1021, subpart D, which applies to 

any rulemaking that interprets or 

amends an existing rule without 

changing the environmental effect of 

that rule. Accordingly, neither an 

environmental assessment nor an 

environmental impact statement is 

required. 

E. Review Under Executive Order 13132 

Executive Order 13132, ‘‘Federalism,’’ 

64 FR 43255 (Aug. 4, 1999) imposes 

certain requirements on agencies 

formulating and implementing policies 

or regulations that preempt State law or 

that have Federalism implications. The 

Executive Order requires agencies to 

examine the constitutional and statutory 

authority supporting any action that 

would limit the policymaking discretion 

of the States and to carefully assess the 

necessity for such actions. The 

Executive Order also requires agencies 

to have an accountable process to 

ensure meaningful and timely input by 

State and local officials in the 

development of regulatory policies that 

have Federalism implications. On 

March 14, 2000, DOE published a 

statement of policy describing the 

intergovernmental consultation process 

it will follow in the development of 

such regulations. 65 FR 13735. DOE 

examined this final rule and determined 

that it will not have a substantial direct 

effect on the States, on the relationship 

between the national government and 

the States, or on the distribution of 

power and responsibilities among the 

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 final rule. 

States can petition DOE for exemption 

from such preemption to the extent, and 

based on criteria, set forth in EPCA. (42 


srobinson on DSK4SPTVN1PROD with 
65976 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

U.S.C. 6297(d)) No further action is 

required by Executive Order 13132. 

F. Review Under Executive Order 12988 

Regarding the review of existing 

regulations and the promulgation of 

new regulations, section 3(a) of 

Executive Order 12988, ‘‘Civil Justice 

Reform,’’ 61 FR 4729 (Feb. 7, 1996), 

imposes on Federal agencies the general 

duty to adhere to the following 

requirements: (1) Eliminate drafting 

errors and ambiguity; (2) write 

regulations to minimize litigation; (3) 

provide a clear legal standard for 

affected conduct rather than a general 

standard; and (4) promote simplification 

and burden reduction. Section 3(b) of 

Executive Order 12988 specifically 

requires that Executive agencies make 

every reasonable effort to ensure that the 

regulation: (1) Clearly specifies the 

preemptive effect, if any; (2) clearly 

specifies any effect on existing Federal 

law or regulation; (3) provides a clear 

legal standard for affected conduct 

while promoting simplification and 

burden reduction; (4) specifies the 

retroactive effect, if any; (5) adequately 

defines key terms; and (6) addresses 

other important issues affecting clarity 

and general draftsmanship under any 

guidelines issued by the Attorney 

General. Section 3(c) of Executive Order 

12988 requires Executive agencies to 

review regulations in light of applicable 

standards in sections 3(a) and 3(b) to 

determine whether they are met or it is 

unreasonable to meet one or more of 

them. DOE has completed the required 

review and determined that, to the 

extent permitted by law, this final rule 

meets the relevant standards of 

Executive Order 12988. 

G. Review Under the Unfunded 

Mandates Reform Act of 1995 

Title II of the Unfunded Mandates 

Reform Act of 1995 (UMRA) requires 

each Federal agency to assess the effects 

of Federal regulatory actions on State, 

local, and Tribal governments and the 

private sector. Public Law 104–4, sec. 

201 (codified at 2 U.S.C. 1531). For a 

regulatory action resulting in a rule that 

may cause the expenditure by State, 

local, and Tribal governments, in the 

aggregate, or by the private sector of 

$100 million or more in any one year 

(adjusted annually for inflation), section 

202 of UMRA requires a Federal agency 

to publish a written statement that 

estimates the resulting costs, benefits, 

and other effects on the national 

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

UMRA also requires a Federal agency to 

develop an effective process to permit 

timely input by elected officers of State, 

local, and Tribal governments on a 

proposed ‘‘significant intergovernmental 

mandate,’’ and requires an agency plan 

for giving notice and opportunity for 

timely input to potentially affected 

small governments before establishing 

any requirements that might 

significantly or uniquely affect small 

governments. On March 18, 1997, DOE 

published a statement of policy on its 

process for intergovernmental 

consultation under UMRA. 62 FR 

12820; also available at www.gc.doe.gov. 

DOE examined today’s final rule 

according to UMRA and its statement of 

policy and determined that the rule 

contains neither an intergovernmental 

mandate, nor a mandate that may result 

in the expenditure of $100 million or 

more in any year, so these requirements 

do not apply. 

H. Review Under the Treasury and 

General Government Appropriations 

Act, 1999 

Section 654 of the Treasury and 

General Government Appropriations 

Act, 1999 (Pub. L. 105–277) requires 

Federal agencies to issue a Family 

Policymaking Assessment for any rule 

that may affect family well-being. 

Today’s final rule will not have any 

impact on the autonomy or integrity of 

the family as an institution. 

Accordingly, DOE has concluded that it 

is not necessary to prepare a Family 

Policymaking Assessment. 

I. Review Under Executive Order 12630 

DOE has determined, under Executive 

Order 12630, ‘‘Governmental Actions 

and Interference with Constitutionally 

Protected Property Rights’’ 53 FR 8859 

(Mar.18, 1988), that this regulation will 

not result in any takings that might 

require compensation under the Fifth 

Amendment to the U.S. Constitution. 

J. Review Under Treasury and General 

Government Appropriations Act, 2001 

Section 515 of the Treasury and 

General Government Appropriations 

Act, 2001 (44 U.S.C. 3516 note) provides 

for agencies to review most 

disseminations of information to the 

public under guidelines established by 

each agency pursuant to general 

guidelines issued by OMB. OMB’s 

guidelines were published at 67 FR 

8452 (Feb. 22, 2002), and DOE’s 

guidelines were published at 67 FR 

62446 (Oct. 7, 2002). DOE has reviewed 

today’s final rule under the OMB and 

DOE guidelines and has concluded that 

it is consistent with applicable policies 

in those guidelines. 

K. Review Under Executive Order 13211 

Executive Order 13211, ‘‘Actions 

Concerning Regulations That 

Significantly Affect Energy Supply, 

Distribution, or Use,’’ 66 FR 28355 (May 

22, 2001), requires Federal agencies to 

prepare and submit to OMB, a 

Statement of Energy Effects for any 

significant energy action. A ‘‘significant 

energy action’’ is defined as any action 

by an agency that promulgated or is 

expected to lead to promulgation of a 

final rule, and that: (1) Is a significant 

regulatory action under Executive Order 

12866, or any successor order; and (2) 

is likely to have a significant adverse 

effect on the supply, distribution, or use 

of energy; or (3) is designated by the 

Administrator of OIRA as a significant 

energy action. For any significant energy 

action, the agency must give a detailed 

statement of any adverse effects on 

energy supply, distribution, or use if the 

regulation is implemented, and of 

reasonable alternatives to the action and 

their expected benefits on energy 

supply, distribution, and use. 

Today’s regulatory action is not a 

significant regulatory action under 

Executive Order 12866. Moreover, it 

would not have a significant adverse 

effect on the supply, distribution, or use 

of energy, nor has it been designated as 

a significant energy action by the 

Administrator of OIRA. Therefore, it is 

not a significant energy action, and, 

accordingly, DOE has not prepared a 

Statement of Energy Effects. 

L. Review Under Section 32 of the 

Federal Energy Administration Act of 

1974 

Under section 301 of the Department 

of Energy Organization Act (Pub. L. 95– 

91; 42 U.S.C. 7101), DOE must comply 

with section 32 of the Federal Energy 

Administration Act of 1974, as amended 

by the Federal Energy Administration 

Authorization Act of 1977. (15 U.S.C. 

788; FEAA) Section 32 essentially 

provides in relevant part that, where a 

proposed rule authorizes or requires use 

of commercial standards, the notice of 

proposed rulemaking must inform the 

public of the use and background of 

such standards. In addition, section 

32(c) requires DOE to consult with the 

Attorney General and the Chairman of 

the Federal Trade Commission (FTC) 

concerning the impact of the 

commercial or industry standards on 

competition. 

The amendments to the test 

procedures in today’s final rule 

incorporate testing methods contained 

in certain sections of the following 

commercial standards:

and is unable to conclude whether they 

fully comply with the requirements of 

section 32(b) of the FEAA (i.e., whether 

they were developed in a manner that 

fully provides for public participation, 

comment, and review.) DOE has 

consulted with both the Attorney 

General and the Chairman of the FTC 

about the impact on competition of 

using the methods contained in these 

standards and has received no 

comments objecting to their use. 

M. Congressional Notification 

As required by 5 U.S.C. 801, DOE will 

report to Congress on the promulgation 

of today’s rule before its effective date. 

The report will state that it has been 

determined that the rule is not a ‘‘major 

rule’’ as defined by 5 U.S.C. 804(2). 

V. Approval of the Office of the 

Secretary 

The Secretary of Energy has approved 

publication of this final rule.

Appendix I to Subpart B of Part 430— 

Uniform Test Method for Measuring the 

Energy Consumption of Conventional 

Ranges, Conventional Cooking Tops, 

Conventional Ovens, and Microwave 

Ovens 

Note: The procedures and calculations in 

this Appendix I need not be performed to 

determine compliance with energy 

conservation standards for conventional 

ranges, conventional cooking tops, 

conventional ovens, and microwave ovens at 

this time. However, any representation made 

after April 29, 2013 related to standby mode 

and off mode energy consumption of 

conventional ranges, conventional cooking 

tops, and conventional ovens, and any 

representation made after September 6, 2011 

related to standby mode and off mode energy 

consumption of microwave ovens, must be 

based upon results generated under this test 

procedure, consistent with the requirements 

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

date of any energy conservation standard that 

incorporates standby mode and off mode 

energy consumption, compliance with the 

applicable provisions of this test procedure 

will also be required. Future revisions may 

add relevant provisions for measuring active 

mode in microwave ovens. 

1. Definitions 

1.1 Active mode means a mode in which 

the product is connected to a mains power 

source, has been activated, and is performing 

the main functions of producing heat by 

means of a gas flame, electric resistance 

heating, or microwave energy, or circulating 

air internally or externally to the cooking 

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

associated with an active mode. 

1.2 Built-in means the product is 

supported by surrounding cabinetry, walls, 

or other similar structures. 

1.3 Combined low-power mode means the 

aggregate of available modes other than 

active mode, but including the delay start 

mode portion of active mode. 

1.4 Cycle finished mode means a standby 

mode in which a conventional cooking top, 


srobinson on DSK4SPTVN1PROD with 
65988 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

conventional oven, or conventional range 

provides continuous status display following 

operation in active mode. 

1.5 Drop-in means the product is 

supported by horizontal surface cabinetry. 

1.6 Fan-only mode means an active mode 

that is not user-selectable and in which a fan 

circulates air internally or externally to the 

cooking product for a finite period of time 

after the end of the heating function, where 

the end of the heating function is indicated 

to the consumer by means of a display, 

indicator light, or audible signal. 

1.7 Forced convection means a mode of 

conventional oven operation in which a fan 

is used to circulate the heated air within the 

oven compartment during cooking. 

1.8 Freestanding means the product is not 

supported by surrounding cabinetry, walls, 

or other similar structures. 

1.9 IEC 62301 (First Edition) means the 

test standard published by the International 

Electrotechnical Commission, titled 

‘‘Household electrical appliances— 

Measurement of standby power,’’ Publication 

62301 (First Edition 2005–06) (incorporated 

by reference; see § 430.3). 

1.10 IEC 62301 (Second Edition) means 

the test standard published by the 

International Electrotechnical Commission, 

titled ‘‘Household electrical appliances— 

Measurement of standby power,’’ Publication 

62301 (Edition 2.0 2011–01) (incorporated by 

reference; see § 430.3). 

1.11 Inactive mode means a standby 

mode that facilitates the activation of active 

mode by remote switch (including remote 

control), internal sensor, or timer, or that 

provides continuous status display. 

1.12 Normal non-operating temperature 

means the temperature of all areas of an 

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

of the temperature that the identical areas of 

the same basic model of the appliance would 

attain if it remained in the test room for 24 

hours while not operating with all oven 

doors closed. 

1.13 Off mode means a mode in which 

the product is connected to a mains power 

source and is not providing any active mode 

or standby mode function, and where the 

mode may persist for an indefinite time. An 

indicator that only shows the user that the 

product is in the off position is included 

within the classification of an off mode. 

1.14 Primary energy consumption means 

either the electrical energy consumption of a 

conventional electric oven or the gas energy 

consumption of a conventional gas oven. 

1.15 Secondary energy consumption 

means any electrical energy consumption of 

a conventional gas oven. 

1.16 Standard cubic foot (L) of gas means 

that quantity of gas that occupies 1 cubic foot 

(L) when saturated with water vapor at a 

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

of 30 inches of mercury (101.6 kPa) (density

modes (including activation or deactivation 

of active mode) by remote switch (including 

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

continuous functions, including information 

or status displays (including clocks) or 

sensor-based functions. A timer is a 

continuous clock function (which may or 

may not be associated with a display) that 

provides regular scheduled tasks (e.g., 

switching) and that operates on a continuous 

basis. 

1.18 Thermocouple means a device 

consisting of two dissimilar metals which are 

joined together and, with their associated 

wires, are used to measure temperature by

3. Test Methods and Measurements 

* * * * * 

3.1.1 Conventional oven. Perform a test 

by establishing the testing conditions set 

forth in section 2, Test Conditions, of this 

appendix and turn off the gas flow to the 

conventional cooking top, if so equipped. 

Before beginning the test, the conventional 

oven shall be at its normal non-operating 

temperature as defined in section 1.12 and 

described in section 2.6 of this appendix. Set 

the conventional oven test block W1

approximately in the center of the usable 

baking space. If there is a selector switch for 

selecting the mode of operation of the oven, 

set it for normal baking. If an oven permits 

baking by either forced convection by using 

a fan, or without forced convection, the oven 

is to be tested in each of those two modes. 

The oven shall remain on for one complete 

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

resistance heaters or gas burners after the test 

block temperature has increased 234 °F (130 

°C) above its initial temperature. 

3.1.1.1 Self-cleaning operation of a 

conventional oven. Establish the test 

conditions set forth in section 2, Test 

Conditions, of this appendix. Turn off the gas 

flow to the conventional cooking top. The 

temperature of the conventional oven shall 

be its normal non-operating temperature as 

defined in section 1.12 and described in 

section 2.6 of this appendix. Then set the 

conventional oven’s self-cleaning process in 

accordance with the manufacturer’s 

instructions. If the self-cleaning process is 

adjustable, use the average time 

recommended by the manufacturer for a 

moderately soiled oven. 

3.1.1.2 Conventional oven standby mode 

and off mode power. Establish the standby 

mode and off mode testing conditions set 

forth in section 2, Test Conditions, of this

the oven temperature without cycling on and 

off, measure the energy consumed, EO, when 

the temperature of the block reaches TO (TO

is 234 °F (130 °C) above the initial block 

temperature, TI). If the oven thermostat 

operates by cycling on and off, make the 

following series of measurements: Measure 

the block temperature, TA, and the energy 

consumed, EA, or volume of gas consumed, 

VA, at the end of the last ‘‘ON’’ period of the 

conventional oven before the block reaches 

TO. Measure the block temperature, TB, and 

the energy consumed, EB, or volume of gas 

consumed, VB, at the beginning of the next 

‘‘ON’’ period. Measure the block temperature, 

TC, and the energy consumed, EC, or volume 

of gas consumed, VC, at the end of that ‘‘ON’’ 

period. Measure the block temperature, TD, 

and the energy consumed, ED, or volume of 

gas consumed, VD, at the beginning of the 

following ‘‘ON’’ period. Energy 

measurements for EO, EA, EB, EC, and ED

should be expressed in watt-hours (kJ) for 

conventional electric ovens, and volume 

measurements for VA, VB, VC, and VD should 

be expressed in standard cubic feet (L) of gas 

for conventional gas ovens. For a gas oven, 

measure in watt-hours (kJ) any electrical 

energy, EIO, consumed by an ignition device 

or other electrical components required for 

the operation of a conventional gas oven 

while heating the test block to TO. 

3.2.1.1 Conventional oven average test 

energy consumption. If the conventional 

oven permits baking by either forced 

convection or without forced convection and 

the oven thermostat does not cycle on and 

off, measure the energy consumed with the 

forced convection mode, (EO)1, and without 

the forced convection mode, (EO)2, when the

with and without the forced convection 

mode: Measure the block temperature, TA, 

and the energy consumed, EA, or volume of 

gas consumed, VA, at the end of the last 

‘‘ON’’ period of the conventional oven before 

the block reaches TO. Measure the block 

temperature, TB, and the energy consumed, 

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

beginning of the next ‘‘ON’’ period. Measure 

the block temperature, TC, and the energy 

consumed, EC, or volume of gas consumed, 

VC, at the end of that ‘‘ON’’ period. Measure

EC, and ED should be expressed in watt-hours 

(kJ) for conventional electric ovens, and 

volume measurements for VA, VB, VC, and VD

should be expressed in standard cubic feet 

(L) of gas for conventional gas ovens. For a 

gas oven that can be operated with or without 

forced convection, measure in watt-hours (kJ)

mode is known, the watt-hours consumed 

may be measured for a period of 10 minutes

specified in section 2.9.1.1 of this appendix. 

Multiply this value by the time in minutes 

that the conventional oven remains in fanonly mode, tOF, and divide by 10,000 to

used only if the resulting EOF is 

representative of energy use during the entire 

fan-only mode.

consumption, ES, in watt-hours (kJ) of

1. Scope 

This appendix covers the test requirements 

used to measure the energy performance of 

dehumidifiers. 

2. Definitions 

2.1 ANSI/AHAM DH–1 means the test 

standard published by the American National 

Standards Institute and the Association of 

Home Appliance Manufacturers, titled 

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

(incorporated by reference; see § 430.3). 

2.2 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. 

2.3 Combined low-power mode means the 

aggregate of available modes other than 

active mode. 

2.4 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). 

2.5 IEC 62301 means the test standard 

published by the International 

Electrotechnical Commission, titled 

‘‘Household electrical appliances— 

Measurement of standby power,’’ Publication 

62301 (Edition 2.0 2011–01) (incorporated by 

reference; see § 430.3). 

2.6 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. 

2.7 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. 

2.8 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. 

2.9 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. 

2.10 Standby mode means any modes 

where the dehumidifier is connected to a 

mains power source and offers one or more 

of the following user-oriented or protective 

functions which may persist for an indefinite 

time: 

(1) To facilitate the activation of other 

modes (including activation or deactivation 

of active mode) by remote switch (including 

remote control), internal sensor, or timer; 

(2) Continuous functions, including 

information or status displays (including 

clocks) or sensor-based functions. A timer is 

a continuous clock function (which may or 

may not be associated with a display) that 

provides regular scheduled tasks (e.g., 

switching) and that operates on a continuous 

basis. 

3. Test Apparatus and General Instructions 

3.1 Active mode. The test apparatus and 

instructions for testing dehumidifiers shall 

conform to the requirements specified in 

Section 3, ‘‘Definitions,’’ Section 4, 

‘‘Instrumentation,’’ and Section 5, ‘‘Test 

Procedure,’’ of ANSI/AHAM DH–1 

(incorporated by reference, see § 430.3). 

Record measurements at the resolution of the 

test instrumentation. Round off calculations 

to the same number of significant digits as 

the previous step. Round the final minimum 

energy factor value to two decimal places as 

follows: 

(i) A fractional number at or above the 

midpoint between two consecutive decimal 

places shall be rounded up to the higher of 

the two decimal places; or 

(ii) A fractional number below the 

midpoint between two consecutive decimal 

places shall be rounded down to the lower 

of the two decimal places.

(incorporated by reference, see § 430.3). The 

electrical supply frequency shall be 

maintained ±1 percent. 

3.2.2.2 Supply voltage waveform. For the 

standby mode and off mode testing, maintain 

the electrical supply voltage waveform 

indicated in Section 4, Paragraph 4.3.2 of IEC 

62301, (incorporated by reference; see

section 3.2 of this appendix, ensuring that 

the dehumidifier does not enter active mode 

during the test. For dehumidifiers that take 

some time to enter a stable state from a 

higher power state as discussed in Section 5, 

Paragraph 5.1, Note 1 of IEC 62301, 

(incorporated by reference; see § 430.3), 

allow sufficient time for the dehumidifier to 

reach the lower power state before 

proceeding with the test measurement. 

Follow the test procedure specified in 

Section 5, Paragraph 5.3.2 of IEC 62301 for 

testing in each possible mode as described in 

sections 4.2.1 and 4.2.2 of this appendix. 

4.2.1 If the dehumidifier has an inactive 

mode, as defined in section 2.6 of this 

appendix, but not an off mode, as defined in 

section 2.7 of this appendix, measure and 

record the average inactive mode power of 

the dehumidifier, PIA, in watts. Otherwise, if 

the dehumidifier has an off mode, as defined 

in section 2.7 of this appendix, measure and 

record the average off mode power of the 

dehumidifier, POM, in watts. 

4.2.2 If the dehumidifier has an off-cycle 

mode, as defined in section 2.8 of this 

appendix, measure and record the average 

off-cycle mode power of the dehumidifier, 

POC, in watts. 

5. Calculation of Derived Results From Test 

Measurements 

5.1 Annual combined low-power mode 

energy consumption. Calculate the annual 

combined low-power mode energy 

consumption for dehumidifiers, ETLP,

expressed in kilowatt-hours per year, 

according to the following: 

ETLP = [(PIO × SIO) + (POC × SOC)] × K 

Where: 

PIO = PIA, dehumidifier inactive mode power, 

or POM, dehumidifier off 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. 

SIO = 1840,5 dehumidifier inactive mode or 

off mode annual hours. 

SOC = 1840,5 dehumidifier off-cycle 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 + ((ETLP × 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. 

ETLP = 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.
