For appliances having their thermostats and acceleration resistor connected to the mains, the same measurements shall be performed in addition with the switch in zero position.
When, in practice, the thermostat may be used together with inductive loads (e.g. relay,contactor) all measurements shall be performed using such a device, having the highest coil inductance used in practice.
In order to obtain a satisfactory measurement, it is essential that the contacts shall be operated for a sufficient number of times with a suitable load to ensure that the levels of disturbance are representative of those encountered in normal operation.
7.3.4.15 Rice cookers shall be tested with the rated capacity of tap water and with the lid closed. If there is no indication of the rated capacity, the cooker shall be filled with 80 % water of the maximum capacity of the inner pot.
In case of the rice cooker operating in induction heating function, measurement shall be made under the condition of maximum input power and the same conditions as specified in Annex B.
If the cooker automatically enters a “keep warm”-mode at the end of the cooking process, the cooking mode should be ended manually and the click measurement shall be started at the time of the first operation of the thermostat, which controls the “keep warm” temperature.
As far as continuous disturbance occurs no special operating conditions are to be observed; the appliance is to be operated according to the manufacturer's instruction for use.
In case of automatic machines, where individual switching processes are (directly or indirectly) manually operated, and whereby no more than two clicks per sales, dispensing or similar processes are produced, 4.2.3.1 is applicable.
