Summary of Test Method4.1 The booster temperature (for high temperature ma-ch
44、ines) and wash tank temperature are calibrated and verified.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
45、printed on the heating element, all further testing ceases.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
46、 (V) with no change in components), the voltage selectedby 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 th
47、e two voltages. Therefore the tests may be performedat 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
48、 difference is greater than 5 %,terminate testing and contact 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 maint
49、ained, but nowashing is taking place. This test is run 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 monitored 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 th
