scope:

1.1 This test method covers the evaluation of the energy and water consumption of single-rack, door-type commercial dishwashers (hereafter referred to as dishwashers). Dishwashers may have a remote or self-contained booster heater. This test method does not address cleaning or sanitizing performance.

1.2 This test method is applicable to both hot water sanitizing and chemical sanitizing stationary rack machines, which include undercounter single rack machines; upright door-type machines; pot, pan, and utensil machines; fresh water rinse machines; and fill-and-dump machines. Dishwasher tank heaters are evaluated separately from the booster heater.

1.3 The following procedures are included in this test method:

1.3.1 Procedures to Confirm Dishwasher is Operating Properly Prior to Performance TestingMaximum energy input rate of the tank heaters (see ).

Maximum energy input rate of the booster heater, if applicable (see ).

Water consumption calibration (see ).

Booster temperature calibration, if applicable (see ).

Wash tank temperature calibration (see ).

1.3.2 Energy Usage and Cycle Rate Performance TestsWashing energy test ().

Tank heater idle energy rate (door(s) open and door(s) closed) (see ).

Booster idle energy rate, if provided (see ).

1.4 The values stated in inch-pound units are to be regarded as standard. The SI units given in parentheses are for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
