ASTM F1696-20

Standard Test Method for Energy Performance of Stationary-Rack, Door-Type Commercial Dishwashing Machines

SIGNIFICANCE AND USE
5.1 The maximum energy input rate test is used to confirm that the dishwasher is operating at the manufacturer's rated input prior to further testing. This test would also indicate any problems with the electric power supply, gas service pressure, or steam supply flow or pressure.  
5.2 The tank and booster temperature are verified and water consumption is adjusted to NSF specifications to ensure that the test is applied to a properly functioning dishwasher.  
5.3 Because much of a dishwasher's operating period is spent in the idle condition, tank heater and booster idle energy consumption rate is an important part of predicting an end user's energy consumption. The test is run with the door(s) open and with the door(s) closed, so that the energy use of both end-user behaviors can be characterized.  
5.4 A washing energy test generates an energy per rack usage. This is useful both as a measure for comparing the energy performance of one dishwasher to another and as a predictor of an end users energy consumption.  
5.5 Water-consumption characterization is useful for estimating water and sewage costs associated with dishwashing machine operation.
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 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.  
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:  
1.3.1.1 Maximum energy input rate of the tank heaters (see 10.3).
1.3.1.2 Maximum energy input rate of the booster heater, if applicable (see 10.4).
1.3.1.3 Water consumption calibration (see 10.5).
1.3.1.4 Booster temperature calibration, if applicable (see 10.2).
1.3.1.5 Tank temperature calibration (see 10.7.7.1 and 10.7.7.2).  
1.3.2 Energy Usage and Cycle Rate Performance Tests:  
1.3.2.1 Washing energy test (see 10.7).
1.3.2.2 Idle energy rate (door(s) open and door(s) closed) (see 10.8).  
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.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
