Standard Test Method for Performance of Rack Conveyor, Commercial Dishwashing Machines
SCOPE
1.1 This test method evaluates the energy and water consumption of rack conveyor, commercial dishwashing machines, hereafter referred to as dishwashers. Dishwashers may have remote or self-contained booster heater. This procedure does not address cleaning or sanitizing performance.
1.2 This test method is applicable to both hot water sanitizing and chemical sanitizing rack conveyor machines, which include both single tank and multiple tank 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 Testing Maximum energy input rate of the tank heaters ().
Maximum energy input rate of the booster heater, if applicable ().
Final sanitizing rinse water consumption calibration ().
Booster temperature calibration, if applicable ().
Wash tank temperature calibration ().
Wash tank pump and conveyor motor calibration ().
1.3.2 Energy Usage and Cycle Rate Performance Tests Washing energy performance test ().
Tank heater idle energy rate ().
Booster idle energy rate, if provided ().
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.

1. Scope
1.1This test method evaluates the energy consumption of rack conveyor, hot water sanitizing, commercial dishwashing
machines, hereafter referred to as dishwashers. It excludes rack conveyor, chemical sanitizing, commercial dishwashing machines,
