Clothes Washer Test

Procedure

Rulemaking (s) Overview

PEAL 11/15/95

Normal Cycle Temperature

Selection "lockout"

• Clothes washer prevents use of a

temperature selection in the normal cycle

that is available in another cycle (i.e. heavy

duty, delicate etc.).

• Energy consumption is only calculated in

the normal cycle, so energy representation

is understated.

• Main issue involves proration percentages

between cycles for energy calculations.

• Normal Cycle Temperature Selection

DOE Proposed Rule "Interim Test

Procedure" - Published March 23, 1995

• AHAM Recommended Test Procedure

"Future Test Procedure" - Submitted as comment to

DOE, July 5, 1995

Normal Cycle Temperature

Selection "lockout"

• Department's Reproposal of May 95

reduced credit, from 75% to 20%,

subjectively.

• Whirlpool submitted public data and

maintained 75% credit position with

ultimate low of 40%.

• DOE reviewed confidential data and has

gotten Whirlpool to agree to 32%.

1 Credit is obtained by using the appropriate percentage for the normal cycle when energy is not bang used (i.e.

warm rinse is actually a cold rinse)

DOE Proposed Rule

"Interim Test Procedure"

• Proposed rule will not effect energy

consumption of any existing model which

must meet a performance standard.

• Test procedure improved to add provisons

for testing innovative technologies.

• Revises certification report requirements to

ensure Energy Factors are provided for

Dishwashers, Clothes Washers and

Clothes Dryers.

AHAM Recommended Future

Test Procedure

"For 1999 Standards"

• DOE.interfaced with AHAM task force

leader for all of 1994.

• DOE attended and provided extensive

input at industry workshop in Feb. 95.

• Provided follow-up comment and got

industry to agree on revised Modified

Energy Factor.

DOE Proposed Rule

"Interim Test Procedure"

• Water-heating clothes washers

• Remaining Moisture Content (RMC)

• Automatic Fill Control

• Modified. Energy Factor

• Reduction of yearly cycles (416 to 392)

• Clarification for similarly labeled

temperature selections (auto-temp)

• General revisions (i.e. tolerances, typos,

electrical supply etc.)

AHAM Recommended Future

Test Procedure

"For 1999 Standards"

• Revises test procedure to reflect

consumer usage habits.

• Results in approximatley 25-30%

energy reduction.

• Changes approach for testing multiple

temperature selections to two (hottest

& coldest) and calculation for

intermediate if "uniformly distributed".

AHAM Recommended Future

Test Procedure

"For 1999 Standards"

• Develops test load table dependent upon

clothes washer capacity, including maximum,

minimum and average load size (current

procedure does not use a test load for

top-loaders).

• Provides Load Utilization Factor for automatic fill

control washers (i.e. 74% of consumers use

average load size).

• Provides field testing requirements for "'fuzzy

logic" machines which vary wash characteristics

based on soil condition.

Issues Discussed in Reopen of

Comment Period NOPR

• Annual Energy Consumption (cycles/yr)

• Capacity Measurement - Top-loading

methodology and potential horizontal-axis credit.

• Electrical Energy Supply - Disconnecting of

console lights.

• Remaining Moisture. Content - Dryer Utilization

Factor, Effect of RMC with change in load size,

Multiple RMC levels within Energy Test Cycle

(i.e. spin speed, spin duration)

Rulemaking Implementation

Strategy

• Issue Reopen of Comment Period Notice to

request comment on the AHAM procedure with

discussion of controversial issues.

• Issue one final rule for all three issues (i.e.

Lockout, Interim and Future).

• Final rule will issue two appendices "J" and "J1."

• Appendix "J" will become effective immediatley

upon issuance (i.e. March 95 with 180 day

reporting allowance window) and "J1" becoming

effective with the next round of standards (i.e.

2000)

Issues Discussed cont.

• Sodium Hypochlorite Bleach

• Temperature Use Factors - linear regression with and

without future projection, rinse TUFS

• Uniformly Distributed Temperature Selections

• Water Consumption Factor - (cubic feet/gallon/cycle or

gallon/cycle/cubic feet)

• Water heating clothes washers - Ambient conditions,

AHAM concern (possible line loss) and energy for gas

water heating labeling

• Reporting Requirements
