Standard Test Method for Energy Performance of Single-Rack, Door-Type Commercial Dishwashing Machines
 N F1696

Annotation

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.

This test method is applicable to both hot water sanitizing and chemical sanitizing stationary rack machines, which includes 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. Machines designed to be interchangeable in the field from high temp and low temp (that is, Dual Sanitizing Machines) and vice versa, shall be tested at both settings. Machines should be set for factory settings. If a dishwasher includes a booster heater as an option, energy should be sub metered separately for the booster heater. 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.

The following procedures are included in this test method:

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

Maximum energy input rate of the tank heaters (see 10.3).

Maximum energy input rate of the booster heater, if applicable (see 10.4).

Water consumption calibration (see 10.5).
