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. Rackless conveyors (i.e. flight type machines) are included. Dishwasher tank heaters are evaluated separately from the booster heater. Machines designed to be interchangeable in the field from high temp and low temp (i.e. Dual Sanitizing Machines) and vice versa, shall be tested at both settings. Machines should be set for factory settings. If a dishwasher includes a prewash tank heater as an option, energy should be submetered separately for the prewash tank heater. This test method may be used for dishwashers with steam coil tank or booster heat, but not dishwashers with steam injection tank or booster heat. When the test method specifies to use the data plate or manufacturer’s recommendations, instructions, specifications, or requirements, the information source shall be used in the following order of preference and documented in the test report: data plate, user manual, communication with manufacturer.
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:
220.127.116.11 Maximum energy input rate of the tank heaters ( ).
18.104.22.168 Maximum energy input rate of the booster heater, if applicable ( ).
22.214.171.124 Final sanitizing rinse water consumption calibration ( ).
126.96.36.199 Booster temperature calibration, if applicable ( ).
188.8.131.52 Wash tank temperature calibration ( ).
184.108.40.206 Wash tank pump and conveyor motor calibration ( ).
1.3.2 Energy Usage and Cycle Rate Performance Tests:
220.127.116.11 Washing energy performance test ( ).
18.104.22.168 Tank heater idle energy rate ( ).
22.214.171.124 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.
1.5 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.
