Summary of Test Method4.1 The booster temperature (for high temperature ma-chines) and wash tank temperature are calibrated and veri
42、fied.4.2 The maximum energy input rate of the tank heater andthe booster heater is determined to check whether the dish-washer is operating at the manufacturers rated input. If themeasured input rate is not within5%oftherated input or therating printed on the heating element, all further testing cea
43、ses.NOTE 1It is the intent of the testing procedure herein to evaluate theperformance of a dishwasher at its rated gas pressure or electric voltage.If an electric unit is rated dual voltage (that is, designed to operate at either208 or 240 volts (V) with no change in components), the voltage selecte
44、dby the manufacturer or tester, or both, shall be reported. If a dishwasher isdesigned to operate at two voltages without a change in the resistance ofthe heating elements, the performance of the unit (for example, recoverytime) may differ at the two voltages. Therefore the tests may be performedat
45、both voltages and results reported accordingly.4.3 The water consumption is adjusted to the manufactur-ers rated water consumption per NSF/ANSI Standard 3.Report the measured consumption and confirm that it is within5 % of the NSF rating. If the difference is greater than 5 %,terminate testing and c
46、ontact the manufacturer. The manufac-turer may make appropriate changes or adjustments to thedishwasher or provide another unit for testing.4.4 The dishwasher energy rate is determined at idle, that is,when the tank temperature(s) is being maintained, but nowashing is taking place. This test is run
47、with the door(s) closed(see 10.8).4.5 The booster heater idle energy rate is determined (see10.9).4.6 The dishwasher and booster energy consumption perrack of dishes or glasses is determined by washing racks loadedwith a specified quantity of dishes or glasses (see 10.7).4.7 Water consumption is mon
48、itored during testing to deter-mine the rate of water usage.5. Significance and Use5.1 The maximum energy input rate test is used to confirmthat the dishwasher is operating at the manufacturers ratedinput prior to further testing. This test would also indicate anyproblems with the electric power sup
49、ply, gas service pressure,or steam supply flow or pressure.5.2 The tank and booster temperature are verified and waterconsumption is adjusted to NSF specifications to ensure thatthe test is applied to a properly functioning dishwasher.5.3 Because much of a dishwashers operating period isspent in the idle condition, tank heater and booster idle energyconsumption rate is an important part of predicting an endusers energy consumption. The test is run with the door(s)open and with the door(s) closed, so that the energy use of bo
