Currently. under the existing lest

Recognizing thaI the utility of an al!·

with its fresh food storage capability.

Today's Dnnl rule includes these 

provisions. 

Delermination of Enersy 

Consumptjon Based on Fresh Food 

Compartment Temperature. Since the 

temperature in the freezer compartment 

of an 21!-refri"erator is no! a critical 

operating par;meter. the July 14. 1980 

proposal called for the determination of 

energy consumption to be based on the 

lemperuture in the fresh food 

compartment. The "standardized" fresh 

food r~mparlmen! temperature. 

proposed <'0 July 14. 1980. was 38'F 

(J.3·C). The July 14 notice also proposed 

that no temperature measurements be 

made in the freezer compartlTlenl. No 

comments were received regarding the 

proposed changes. Today's final rule 

incorporates these changes. The 

provisions for testing ell.refrigerators 

are the SGme as those for testing single 

control device refrigerators (described 

in Section 2. infra) with the exception 

that only fresh food compartment 

tcmperaturr. is used in determining per 

cycle energy consumption. 

(c) Calculation of Adjusted Tolal 

Volume. \\'hile the July 14. 1980. 

proposal broke oul all-refrigerators as a 

type of refrigerator. it did not provide for 

calculutlng the adjusled tolal volume of 

an ull.refrige:alor differently from that 

of a refrigerator. Adjusted total volume 

is a mensu:e of useful output of services 

for refrigerators and refrigerator. 

freezers. and, freezers and is necessary 

fcr compu!!ng Energy Factor tE.FJ. the 

meosure of Ihe ovcTnll efficiency of the 

product. The adjusted total volume III 

divided by the per cycle energy 

consumption of the unit 10 determine the 

F.F. (Per cycle energy consumption is a 

calculnted Villus e'lulvuirnt to the 

amount ol energy thol would be 

consumed by 8 unit over 8 24 hour 

period.) Af:cr actual freezer 

compartment Bnd fresh food 

comportment volume have been 

determined. the adjusted total volume of 

the unit is culcuiated by mul!iplying the 

freezer compartment volurr.e by an 

adjustment factur und adding the result 

to the fresh rood compartment volume. 

Included in the July 14 comments 

rela!lng 10 all·refrigerators were 

recommendations to change the 

ndjuslmenl factor from 1.44 (as yrovided 

for rcfrige"alors] to either 1.12 or 1.0. 

The 1.12 factor Wll9 based on the 

assumption trw! all·rd,igerelor freezer 

compartments would be at a 

temperature of 3Z'F [O'C) when the fresh 

food comparlment temperature was 38'F 

(3.3'C). The adjustment f;;eler of 1.0 wus 

recornmend("d on the basis lhal the 

volume of the freezer compartme::1 or un 

all.refrigerator. being small and of 

limited \,tiIily. should not he "adjusted," 

In other words. this eommenler 

recommended that the adjusted total 

....olume of an all·refrigerator be equal 10 

its bctua! tolal volume. DOE had no 

information 10 substantiate either claim. 

Lacking such data and considering thaI 

use of a 1.12 adjustment factor instead 

of a 1.0 adjnslment factor will mah a 

djfference of only 0.00 cubic feet at the 

most in the adjusted tolal volume of an 

all·refrigerator. DO::: believed that the 

adjustment factor shcJuld be 1.0. Thus. 

this value was proposed in the October

Delermination of Enersy 

Consumptjon Based on Fresh Food 

Compartment Temperature. Since the 

temperature in the freezer compartment 

of an 21!-refri"erator is no! a critical 

operating par;meter. the July 14. 1980 

proposal called for the determination of 

energy consumption to be based on the 

lemperuture in the fresh food 

compartment. The "standardized" fresh 

food r~mparlmen! temperature. 

proposed <'0 July 14. 1980. was 38'F 

(J.3·C). The July 14 notice also proposed 

that no temperature measurements be 

made in the freezer compartlTlenl. No 

comments were received regarding the 

proposed changes. Today's final rule 

incorporates these changes. The 

provisions for testing ell.refrigerators 

are the SGme as those for testing single 

control device refrigerators (described 

in Section 2. infra) with the exception 

that only fresh food compartment 

tcmperaturr. is used in determining per 

cycle energy consumption. 

(c) Calculation of Adjusted Tolal 

Volume. \\'hile the July 14. 1980. 

proposal broke oul all-refrigerators as a 

type of refrigerator. it did not provide for 

calculutlng the adjusled tolal volume of 

an ull.refrige:alor differently from that 

of a refrigerator. Adjusted total volume 

is a mensu:e of useful output of services 

for refrigerators and refrigerator. 

freezers. and, freezers and is necessary 

fcr compu!!ng Energy Factor tE.FJ. the 

meosure of Ihe ovcTnll efficiency of the 

product. The adjusted total volume III 

divided by the per cycle energy 

consumption of the unit 10 determine the 

F.F. (Per cycle energy consumption is a 

calculnted Villus e'lulvuirnt to the 

amount ol energy thol would be 

consumed by 8 unit over 8 24 hour 

period.) Af:cr actual freezer 

compartment Bnd fresh food 

comportment volume have been 

determined. the adjusted total volume of 

the unit is culcuiated by mul!iplying the 

freezer compartment volurr.e by an 

adjustment factur und adding the result 

to the fresh rood compartment volume. 

Included in the July 14 comments 

rela!lng 10 all·refrigerators were 

recommendations to change the 

ndjuslmenl factor from 1.44 (as yrovided 

for rcfrige"alors] to either 1.12 or 1.0. 

The 1.12 factor Wll9 based on the 

assumption trw! all·rd,igerelor freezer 

compartments would be at a 

temperature of 3Z'F [O'C) when the fresh 

food comparlment temperature was 38'F 

(3.3'C). The adjustment f;;eler of 1.0 wus 

recornmend("d on the basis lhal the 

volume of the freezer compartme::1 or un 

all.refrigerator. being small and of 

limited \,tiIily. should not he "adjusted," 

In other words. this eommenler 

recommended that the adjusted total 

....olume of an all·refrigerator be equal 10 

its bctua! tolal volume. DOE had no 

information 10 substantiate either claim. 

Lacking such data and considering thaI 

use of a 1.12 adjustment factor instead 

of a 1.0 adjnslment factor will mah a 

djfference of only 0.00 cubic feet at the 

most in the adjusted tolal volume of an 

all·refrigerator. DO::: believed that the 

adjustment factor shcJuld be 1.0. Thus. 

this value was proposed in the October 

14.1981. notice as the adjustment factor 

for cnlculaling the adjusted total volume 

of an all-refrigerator. No comments were 

received in response to the October 14 

propo!;al relaling 10 this issue. Today's 

final rule prescribes an adjustment 

factor of 1.0 for calculating the adjusted 

total \'olume of on all·refrigerator. 

[d) Calculation of Per Cycle Energy 

Consumption. Equations for calculating 

per cycle energy consumption are 

included in todav's final rule. These 

equnlions replace the graphical 

eniluulion proce~s of the existing 

procedure, When straight lines are used

calculated is taken as the per cycle

In reviewing the July 14 proposal. NBS

Although the likelihood of these cases

The £irst case would be a product ror

fresh food compartment temperature 

cannot be set above 4S'F (7.Z'C).

case. the per cycle energy consumption 

of the unit shuil be determined by

Today's final rule also incorporates an 

alternate lest method Ihat allows the

For refrigerators and refrigerator- .

calculated for both of these conditions. 

The reported value of per cycle energy 

consumption is then selected as the 

higher of the two calculated values. 

For freezers. per cycle energy 

cOllsumption is calculated by using one 

of the two formulas found in section 6.2 

of Appendix B1. If the compartment 

lemperllture cannot be set at or above

formulas. one of which determines

temperature control and a fresh food 

compartment temperature control·be 

. tested four times; once at each of the 

combinations of the extreme position 

settings of the controls (w8Jln/warm. 

warm/cold. cold/warm. and cold/cold). 

The test values obtained are: the 

average freezer compartment 

temperature, the average fresh food 

compartment temperature and thr. 

energy consumed during the test. If the 

unit has an anti-sweat heater switch. it 

must be tested another four times with 

the switch set in its other position. 

Under existing procedures. the first 

step in determining per cycle energy 

consumption after testing is completed 

is to plot two graphs. one above the 

other. The lower graph is a plot of 

freezer compartmentteroperalure test 

values versus fresh food compartment 

temperature lest values. l1JC upper 

graph is a plot of energy consumption 

test values versus fresh food 

compartment tcmperuture test vallies. 

(The axes of Ihe two graphs are oriented 

such that the freezer compartment 

temperature axis (lower graph) and the 

energy consumption axis (upper graph) 

lie on the same vertical line.) 

The freezer compartment and fresh 

food compartment temperature values of 

each test become the coordinates of the 

points to be plotted on the freezer 

compartment temperature versus fresh 

food compartment temperature graph. 

Once plolled. these four points are 

conr.ected by four straight lines to form 

a quadrilateral figure or envelope. 

(These Iincs denote the boundaries of 

attuinable freezer compartment and 

fresh food comportment temperatures 

for all possible combinations of sellings 

of tho temperature controls.) A 

horizontllillne 18 then drawn through the 

envelope at tho appropriate 

standardized frel'zer compartment 

temperature for the product be inS 'tesled 

(lS'F (-9.4'C) for refrigerators. 

excluding all-refrigerators. and S"F 

1-1S'C) for refrigerator-freezerll). Thl' 

two points where this line intenects the 

boundnry of the envelope rt'present the 

lowest and highest fresh fooo 

compartment temperaturt's attainable 

with tho freezer compartment at the 

standardized tempereture. 

The next step in the determination of 

per cycle energy consumption is to plot 

the energy consumption value5 from 

each test aa a point on the energy 

consumption versus fresh food 

comportment temperature graph. These 

four points are connected by four 

atTaigh! lines 10 form an energy use 

I envelope. Vertical lines are prujected 

upwarJs from the two points un the 

lower groph. tha t represent the highcst 

and lowest fresh food compartment 

temperatures ettaine.ble with the freezer 

compartment at the standardized 

temperature. to intersect the 

corresponding boundary lines of the 

energy use envelope in the upper graph. 

These two points of intersection 

correspond to the maximum and 

mininlUIn energy consumption values 

associated v.rith the freezer compartment 

at the standardized temperatcre. The 

average of these two values is taken as 

the per cycle energy consumption value. 

AHAM petitioned that a two point 

test rather than the existing four point 

lest be used for testing multiple control 

automatic defrost refrigerator-freezers. 

In accordance ..... ith the AHA..\.f proposal. 

a first test shall be conducted with each 

temperatures control set at the midpoint 

of its range [mid/mid). Fresh food and 

freezer compartment temperature and 

energy consumption are to be measured. 

If the midpoint control positions (midI 

mid) result in an average freezer 

compartment temperature grealer than 

S'F (-lS°C]. the standardized freezer 

compartment temperature for a 

refrigera tor-freezer. the controls are to 

be resel to their coldest positions (cold! 

cold) for the second test. If the midpoint 

controls positions (mid/mid) result in an 

average freezer compartment 

tempera ture less than S'F (-lS'C). the 

control Bre to be reselto their warmest 

positions (warm/warm) for the second 

test. The resulting compartment 

temperature lest values and the energy 

consumption lest values are plotted on a 

graph Bnd the per cycle energy 

consumption of the unit is determined at 

the S'F (-lS'C), standardized freezer 

compartment temperature. AHAM 

contended that the results of the two 

point lest would differ bUllllightly from 

the results of the four point test run on 

the 8ame units. 

DOE and ~BS carefully analyzed this 

request for a change in the test 

procedure and find \I an ecceptable 

approoch thot will reduce the 

burdensomeness of the testing process. 

On the freezer compartment 

temperature versus fresb food 

compartment temperature graph used in 

the current procedure. a midpoint setting 

or the temperature controls (mid/mid) as 

AllAM proposed. would p:oduce a point 

on the graph located ne:l1' the center or 

the envelope previously described. A 

line can be drawn from this mid/mid 

setting data point to either the cold/cold 

setting data point or the warm/warm 

selling dala pOint which will cross a 

horizontal line corresponding to a 

freezer compartment temperature of S"F 

(-15'C). The point of interseclion of 

these two lines will be about half way 

between the earlier described maximum 

and minimum fresh food compartment 

temperature values with the freezers 

compartment alS'F (-lS°C). Similarly. 

a mld/mid setting data point will 

produce a point near the center of the 

four point energy use envelope on the 

energy consumption versus fresh food 

compartment temperature graph. By 

projecting a vertical line upward from 

the 5'( {-lS'C) freezer compartment 

temperature Intersection point on the 

lower graph to intersect a line 

connecting the mid/mid setting data 

point and the cold/cold or lne warm! 

warm setting data point on the upper 

graph. the energy that the unit would 

consume to attain Ihis temperature can 

be found. 

In analyzing the AHAM proposal,' 

NBS determined thaI the approach of 

conducting 8 two point test inslead of a 

four point test could be applied to all 

multiple control refrigerators and 

refrigerator-freezers and was not iust 

applicable to multiple control automatic 

defrost referigerator-freezers. l\'lJS 

confirmed that both the grapbical and 

the mathematical method for 

determining per cycle energy 

consumption using only two lesls gave 

test results which varied no more than 

four percent from the existing test 

procedure. Part of this variation may be 

due to Inaccuracies in setting Ihe midI 

mid position on controls lhat have 

widely separated control setting 

markings. Some of Ihese controls also 

have detents al these markings that can 

result in large differences between the 

midpoint setting and the nenrest marked 

or detent setllng. Consequently. today's 

final rule prescribes a two-point lest for 

mutlple control refrigerators and 

refrigerator-freezers but requires that 

the controlll be set at the midpoint of 

their range for testing even If detente 

have to be mechanically overridden.

parameter. An air gap of .Il to 1;; inches 

(1.5104 cm) between the packages and 

the freezer walls is specified in the 

existing test procedure and the use of 

insulating spaces is permilled to 

maintain Ihis gap. Even with spacers. it 

is very difficult to arrange the load 

packages in a manner such that the gap 

is maintained. Also. normal vibrations 

such as those caused by the compressor 

motor slarling and stopping can cause 

the food packages to shift position Bnd 

the air gap to change. NBS concluded 

that tests with Bnd without a load in the 

freezer compartment will produce 

essentially the same test results if the 

load is arranged according to 

specifications. Blocking any of the air 

gaps uffects the results by producing 

different energy usage figures. The 

elimination of the test load should not 

onl\, reduce the burdensomeness of the 

lesi but should also provide a more 

repeatable lest. Consequently. today's 

final rule does not require a load in the 

compartment of automatic defrost 

refrigera tor-freezers. 

As a result of Ihis change. the existing 

method ur measuring freezer

concluded thai test procedures for nontime initiated defrost products are not 

currently needed. H such products are

existing test procedures do not 

accurately measnre the true energy

u. Long-time Automatic Defrost. One 

commenter. when reviewing the July 14. 

1980. proposed non-time initiated defrost 

procedures. noted that these procedures 

could be adapted very easily for testing 

newly-designed automatic defrost 

products which operate for unusually 

long time periods. i.e .. greater then 24 

hours. between defrost periods. NBS 

investigated this recommendation and 

found thot such a procedure could 

greatly reduce test time for such product 

designs. Blnee a test point that may 

currently require four days of testing 

might be obtained in less than 24 hOUfS 

of testing \vith almosl no loss of 

Llccurucy. Consequently. an optional 

procedure for testing long-time 

automatic defrost products. pallerned

procedure proposed on Juiy 14. 1980. 

was incorporaled into Ihe October 14,

Mound the piH:kil~f'~ is iJ \·ery important 

parameter. An air gap of .Il to 1;; inches 

(1.5104 cm) between the packages and 

the freezer walls is specified in the 

existing test procedure and the use of 

insulating spaces is permilled to 

maintain Ihis gap. Even with spacers. it 

is very difficult to arrange the load 

packages in a manner such that the gap 

is maintained. Also. normal vibrations 

such as those caused by the compressor 

motor slarling and stopping can cause 

the food packages to shift position Bnd 

the air gap to change. NBS concluded 

that tests with Bnd without a load in the 

freezer compartment will produce 

essentially the same test results if the 

load is arranged according to 

specifications. Blocking any of the air 

gaps uffects the results by producing 

different energy usage figures. The 

elimination of the test load should not 

onl\, reduce the burdensomeness of the 

lesi but should also provide a more 

repeatable lest. Consequently. today's 

final rule does not require a load in the 

compartment of automatic defrost 

refrigera tor-freezers. 

As a result of Ihis change. the existing 

method ur measuring freezer 

compartment temperature had 10 be 

moJified sbce the tempera lure sensors 

Hre specified 10 be located in the load 

packugcs. AHAM requested that freezer 

temperll t ures be measured in 

accordance with an existing industry 

method in which a thermal mass (wilh II 

heat capacity not to exceed that of 20 

gTums of wllter) is attached to the 

tcmperH lurc sensor. These sensors are 

then located in the freezer compartment 

in the posi!ion~ previously occupied by 

the instrumented frozen food packujjCS. 

r-,'lJS determined that Ihe physical 

dimensions of the thermlll mags cnn

compartmentlcmperature. A thermal 

mass is desirable on !cmperature 

sensors in the freezer uecause of the 

lurllc cyclic temperature vuriution and 

sharp ctllln!;es which make temperature

requircs the usc of wei!;hted

the incliision in the July 14. 19M. 

proposed rule of Il procedure for 

measuring the energy consumption of 

refrigeration products with non-time 

initialed (demnnd) defrost. They slated 

that this Iype of s}'stem. although 

technologically feasible. \s not currently 

marketed in the United Stales. After 

publication of the July 14.1980. proposed 

rule. the "Provisions for the Waiver of 

Consumer Product Test Procedures." 

which "How the Assistant Secretary for 

Conservation and Renewable Energy 

tempor,arily to waive lesl procedures for 

Ii particular covered product. became 

effective. (45 FR &n08. September 26. 

1980). Consequently. DOE has 

concluded thai test procedures for nontime initiated defrost products are not 

currently needed. H such products are 

produced in the future and the then 

existing test procedures do not 

accurately measnre the true energy 

consumption of these products. the 

manufacturer may petition for a waiver 

from the test procedures. (10 CFR 

430.27). Accordingly. loday's rule does 

not include lest I'rocedures for non-time 

initiated defro~: products. 

u. Long-time Automatic Defrost. One 

commenter. when reviewing the July 14. 

1980. proposed non-time initiated defrost 

procedures. noted that these procedures 

could be adapted very easily for testing 

newly-designed automatic defrost 

products which operate for unusually 

long time periods. i.e .. greater then 24 

hours. between defrost periods. NBS 

investigated this recommendation and 

found thot such a procedure could 

greatly reduce test time for such product 

designs. Blnee a test point that may 

currently require four days of testing 

might be obtained in less than 24 hOUfS 

of testing \vith almosl no loss of 

Llccurucy. Consequently. an optional 

procedure for testing long-time 

automatic defrost products. pallerned 

nrter the non-time initialed defrost lest 

procedure proposed on Juiy 14. 1980. 

was incorporaled into Ihe October 14, 

lD81. proposed rule. As proposed. this 

optional test method woulu only apply 

for testing automatic defrost 

rcfrigerutor-freezers and freezers 

designed such Ihat defrost cycles ure 

separated by 14 hours or more of 

compressor-operating time. Using this 

compressor·operuling time criteria. the 

t(ltallesl time required to arrive at a lest 

datu point should he less Ihlln 24 hours 

in most cases. In no case will the lolal 

le~t lime exceC!d 28 hours. A longer test

not result in significantly increased

when tests are in progress. DOE and 

NIlS agree this reguirement is advisable. 

The vertical ambient air temperature 

conditions during the testing process can 

acrect the measured energy use during 

the test. The existing DOE test 

procedt're requires that the operational 

conditions of the AHAM standard 

apply. This standard in turn refers to 

ANSI 838.1-1970 which. in section 6.2.1., 

specifil:'s the maximum allowed vertical 

ambient temperature gradient to be OSF 

per fool (0.geC per meIer). The standard 

docs not specifically stale Ihal this limit 

prevails during the test. The commenters 

poinled this out amI requested that this 

he stated in the final rule. Thus. in 

today"s rule a requirement that the 

,'erlir:al gradient be maintained during 

Ihe lest is included and the temperature 

measurement sensor locations are 

explicitly defined. 

9, fi'eezer Two-point Test. One 

commenler contended that the two-point 

freezer lesl procedure proposed on July 

14.1980. would cause a decrease in 

intraiaboralory repealability of lest 

resulls. which due 10 Ihe statistical 

sampling plnn. would increase the 

numver of lesls required to maintain the 

same Iltatistical confidence le\·el. Dala 

from a single lesl of a single product 

was provided by the commenter and 

was reviewed by NilS and DOE. The 

dula wus found 10 be in(lufficientto 

supporl thn commenter's contention. For 

exumple. the commenter supplied an 

energy consumplion versus freezer 

compartment lempetulure graph 

displaying the test resulls for the lest he 

conducted hut did not identify the 

lempl!rllture control knob settings 

corre!lponding to the duta points 

displrlyed. Also. it appeared that the 

"cold" test point was made with the 

lemperature control device shorlcircuited to clluse the compressor to run 

continuously. Testing in such a manner 

docs not conform to the DOE lesl 

procedures. Finully. any attempl 10 draw 

conc:lusions from a single test of a single 

product is unwise since no !llalislical 

confidence can be assigned to Ihe te~1 

resulls. Thus. no change was made 10 

the DOE test procedure. 

10. Freezer Performance. Storage

cost are the only measures of 

perfurmance for freezers if' the existing 

lesl procedures. One manufacturer 

requested Ihat DOE include anolher 

measure of performance in Ihe freezer 

test procedure. That mO::dsure would be 

the rale of freezing. It would quantify 

thn time it takes a freezer to lower the 

tempera lure of a load. The commenter 

noted thul Ihe p'oposed tesl procedure 

II~millto direct manufacturers towards 

smaller. lower cost refrigeration 

compressors to achieve favornble test 

results (high efficiency ratings and low 

estimated annual operating cost figures). 

Such units would be characterized by 

low freezing rates. The commenter was 

concerned that such units would not 

perform satisfactorily and may pose a 

health hazard since a large room 

temperature load placed in the unit 

might result in the thawing of the 

existing frozen load during the extended 

time period that a freezer with a low 

freezing rate would take to stabilize the 

entire load at a subfreezing temperature. 

By including a measure of freezing rate 

p(;rformance in the test procedure. the 

commenter hopes to discourage 

manufacturers from pursuing such a 

design option. DOE acknowledges that 

such freezer designs are technically 

possible but has no knowledge that such 

freezer designs currently exist. ' 

Therefore, DOE has not opted to include 

a measure of freezing performance in 

the freezer test procedure prescribed 

today. 

11. Accuracy of Tes! Measurements. 

While analyzing public comments to the 

July 14, 1980, proposal. NBS discovered 

that the new AHAM standard (AHAMHRF-1-1979) referenced did not clearly 

define the required accuracy of 

temperature measurements. Section 7.3.1 

of this stllndard states. "Temperature 

readings are to he accurate within 1"F 

(O.S'C)." II is uncleur whether this 

requirement means that the accuracy of 

temperature measurements should be 

±O.S'F (0.Z8'C) 01' ±1.0·F (O.S'C). 

Consequently. for the October 14. 1981. 

proposed rule. DOE added a 

temperllture measurement ar:curacy 

requirement (sections S.l. Appendices 

Al and (31) to specify the same accuracy 

liS thut specified in the e)<.\sling test 

procedure. i.e .. ±O.S'F (0.28'C). 

In response to this proposed rule. one 

commenter requested that this accuracy 

specification ue changed to ± 1.0·F 

(OSC). The commenter interpreted the 

tl'mperllture accuracy requirement of 

AIIAMIIRF-1-1979 to be ± 1.0'F 

(O.S'C). lie aS8P.rted thut even "Special 

Type "T' thermo-couple wire has a limit 

of error of ± O.7S'F (0.42'C) and that 

recorders with a scale fange of 1SO'P 

(83'C) have a limit of error of ± 0.37S'F 

(0.2l'C). It WilS c1uimed thllt these 

factors combine to limit the accuracy of 

temperature measurement to ± 1.13'F 

(0,63'C) which makes the proposed 

accuracy requirement of ± O.S'F (0.28'C) 

unduly burdensome. It is true that the 

conditions staled will not pro\'ide the 

acr:uracy specified by the proposed test 

procedure, However. there are steps 

which can ve tilken to overcome this 

problem. The first step is to qualify, i.e. 

to determine the limit of error 

associated with. the thermocouple wire 

used for the test. This can be done to . 

greater accuracy than a thermocouple' 

wire manufacturer can guarantee for 

large quantities of thermocouple wire. 

The next step is to usc recorders with 

scale ranges of less than lS0'P (83·C). 

The limit of error associated with 

recorders with scale ranges less than 

lS0'P (83'F) is less than for those with 

scale ranges of 1 SO' I-' (83'C) or more. 

Following these two steps. DOE and 

NBS find that temperature 

measurements can be made with an 

accuracy of ± OSF (0.28·C). 

12. Three- rear Period. The July 14. 

1980. proposal would have eliminated 

the existing test procedures for 

refrigerators and refrigerator-freezers. 

and freezers. Since the proposed and 

existing test procedures give almost 

identical results. several commenters 

requested that a three-year period be 

allowed during which the use of either 

test procedure would be allowed. The 

commenters stated that manufacturers 

should have the option to test their 

products under either test procedure 

during this three-year period so they will 

not have to retest immediately all 

models which are currently labeled. 

Since there will be little difference in 

test results between the two test 

procedures. DOE has provided for the 

use of either procedure during a threeyear period In today's final rule. After 

the three-year period. only the 

alternative uniform test methods for 

measureing the energy consumption of 

refrigerators and refrigerator-freezers. 

and freezers (Appendices A1 and B1) 

may be used. 

13. Miscellaneous. After careful 

consideration of all comments and 

further consulta'tion with NI3S. DOE hus 

Incorporated into the final rule some 

editorial and minor technical changes 

thut were not discussed above. For 

example. section 6.1.3 of Appendix A1 

as proposed is the method for 

clliculating the adjusted total volume of 

an all-refrigerator. However. an allrefrigerator is a special case of a 

refrigerator and the methods for 

determining the adjusted total volumes 

of these products differ only by the 

adjustment factors used in the 

calculations. Therefore. section 6.1.3 has 

been deleted and section 6.1.1. the 

method for calculating the adjusted total 

volume of a refrigerator has been 

modified to include the adjustment 

factor for an all-refrigerator and to 

specify that this particular adjustment 

factor be used when calculating the 

adjusted total volume of a refrigerator 

Federal Register I Vol. 47. No. 154 I Tuesday. August 10. 1982 I Rules and Regulations 34523 

when tests are in progress. DOE and 

NIlS agree this reguirement is advisable. 

The vertical ambient air temperature 

conditions during the testing process can 

acrect the measured energy use during 

the test. The existing DOE test 

procedt're requires that the operational 

conditions of the AHAM standard 

apply. This standard in turn refers to 

ANSI 838.1-1970 which. in section 6.2.1., 

specifil:'s the maximum allowed vertical 

ambient temperature gradient to be OSF 

per fool (0.geC per meIer). The standard 

docs not specifically stale Ihal this limit 

prevails during the test. The commenters 

poinled this out amI requested that this 

he stated in the final rule. Thus. in 

today"s rule a requirement that the 

,'erlir:al gradient be maintained during 

Ihe lest is included and the temperature 

measurement sensor locations are 

explicitly defined. 

9, fi'eezer Two-point Test. One 

commenler contended that the two-point 

freezer lesl procedure proposed on July 

14.1980. would cause a decrease in 

intraiaboralory repealability of lest 

resulls. which due 10 Ihe statistical 

sampling plnn. would increase the 

numver of lesls required to maintain the 

same Iltatistical confidence le\·el. Dala 

from a single lesl of a single product 

was provided by the commenter and 

was reviewed by NilS and DOE. The 

dula wus found 10 be in(lufficientto 

supporl thn commenter's contention. For 

exumple. the commenter supplied an 

energy consumplion versus freezer 

compartment lempetulure graph 

displaying the test resulls for the lest he 

conducted hut did not identify the 

lempl!rllture control knob settings 

corre!lponding to the duta points 

displrlyed. Also. it appeared that the 

"cold" test point was made with the 

lemperature control device shorlcircuited to clluse the compressor to run 

continuously. Testing in such a manner 

docs not conform to the DOE lesl 

procedures. Finully. any attempl 10 draw 

conc:lusions from a single test of a single 

product is unwise since no !llalislical 

confidence can be assigned to Ihe te~1 

resulls. Thus. no change was made 10 

the DOE test procedure. 

10. Freezer Performance. Storage 

\'olume and eslimated annual operating 

cost are the only measures of 

perfurmance for freezers if' the existing 

lesl procedures. One manufacturer 

requested Ihat DOE include anolher 

measure of performance in Ihe freezer 

test procedure. That mO::dsure would be 

the rale of freezing. It would quantify 

thn time it takes a freezer to lower the 

tempera lure of a load. The commenter 

noted thul Ihe p'oposed tesl procedure

temperature load placed in the unit 

might result in the thawing of the
