1. Scope

1.1 This test method covers the evaluation of the energy consumption of single-rack, hot water sanitizing, door-type commercial dishwashers (hereafter referred to as dishwashers). This includes under the counter single rack, hot water sanitizing, door type commercial dishwashing machines. This test method excludes single temperature door-type machines. Dishwasher tank heaters are evaluated separately from the booster heater. Dishwashers may have a remote or self-contained booster heater. This test method does not address cleaning or sanitizing performance.

1.2 The following procedures are included in this test method:

1.2.1 Procedures to Confirm Dishwasher is Operating Properly Prior to Performance Testing :

1.2.1.1 Maximum energy input rate of the tank heaters (see 10.2).

1.2.1.2 Maximum energy input rate of the booster heater, if applicable (see 10.3).

1.2.1.3 Water consumption calibration (see 10.4).

1.2.1.4 Booster temperature calibration, if applicable (see 10.5).

1.2.1.5 Wash tank temperature calibration (see 10.6).

1.2.2 Energy Usage and Cycle Rate Performance Tests Washing energy test (10.7).

1.2.2.2 Tank heater idle energy rate (door(s) open and door(s) closed) (see 10.8).

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

1.4 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.
