Testing Methods10.1 Temperature Control Accura
36、cy TestThis test is pre-formed if the induction cooktop includes a temperature settingcapability. The induction cooktop shall be connected to thespecified power source. A thermocouple is applied to thebottom center of a suitable cooking vessel partially filled withwater. The temperature is monitored
37、 as the unit is operated ateach selectable operating temperature (or at 10F (12C)intervals) until the temperature has stabilized. The measuredtemperature shall be within 610F (12C) of the set tempera-ture.10.2 Dry Pan TestThe induction cooktop shall be con-nected to the specified power source. Tempe
38、rature at the topcenter of the unit cooking/warming surface shall be monitoredwith a thermocouple. The unit shall be operated with a dry panload at full power and the temperature monitored. If thetemperature reaches 600F (316C), the unit shall shut downand stop providing power to the load.10.3 Minim
39、um Load Detection TestThe induction cooktopshall be connected to the specified power source. Place a lowcarbon sheet steel disc having a diameter of 2.0 in. (50 mm)and a thickness of 0.6 in. (1.5 mm) flat in the most unfavorableposition in the cooking zone and operate the unit at a full powersetting
40、. The disc shall not be heated in excess of 95F (35C)above the ambient starting temperature.10.4 Operating Power TestThe induction cooktop shall beconnected to the specified power source, using a suitablecalibrated power input measuring device. The cooktop shall beoperated with a pan specified by th
41、e manufacturer at themaximum power setting. The measured power input, correctedfor power factor, shall be within 610 % of the rated power.10.5 Induction Cooktop Effciency Test:10.5.1 Induction cooktop efficiency shall be measured usingTest Methods F1521, and shall be 85 %, power delivered tothe load
42、/input power. The test shall be performed in accordancewith 10.2, “Energy Input Rate”.10.5.2 The test shall be performed using a 20 quart induc-tion compatible stock pot. Examples are Polarware model 203,Vollrath model 77610, and Update International model SPS-20.11. Product Marking11.1 Each inducti
43、on cooktop shall be provided with anidentification plate or label in compliance withANSI Z83.11 orANSI/UL 197.12.
