### 6. FIELD TESTING

6.1 Nonconventional Wash System Energy Consumption Test For washer controls or systems that cannot be adequately measured for energy consumption by the test procedure, or cannot be calculated using a procedure generally accepted by DOE and other manufacturers, a field test must be conducted. The field test shall consist of a minimum of 10 test units and 10 base units, with a minimum of 50 cycles per unit. The units shall be monitored in such a way as to accurately record the total energy consumption per cycle. At a minimum, the following must be measured and recorded throughout the test period for each test unit: Hot water usage in gallons, electrical energy in kilowatt-hours, and the cycles of usage.

Objective of Task Force: 1. Address whether dispensers or other removable parts are to remain in place. 2. Address void spaces which the clothes load would not occupy. 3. Remove confusion about sensor overrides. 4. Define a reasonable and safe water temperature to perform testing. Existing procedure suggests 140° F in density definition. 5. Provide density of water values to avoid potential confusion.

## Capacity

Objective #1: "Removable Parts" Addressed Verbiage employed: "All parts which occupy space within the clothes container and which are recommended for use with the energy test cycle shall be in place...."
Objective #2: "Void Spaces" Addressed Verbiage employed: "... and shall be lined with 2 mil. plastic sheet to prevent water from entering any void space."
Objective #3: Remove "Sensor Override Confusion Removed "(This filling procedure may require overriding the fill level control, or manually completing the fill to the top of the container after the fill sensor terminates the fill at maximum level.)"

Includes deep and spray rinses. Test maximum load size and maximum fill level. Test average load size and fill level (if adaptive). Test minimum load size and minimum fill level.
Additional procedure unique to water heating clothes washers: Measure the total electrical energy for a warm wash cycle and hottest rinse cycle: use maximum, minimum, and average (adaptive) load sizes. Subtract the total electrical energy for the warm wash cycle with cold rinse (previously determined in Section 3.5) from the warm wash and hottest rinse cycle to obtain the additional electrical energy for warm rinse.
