Question:
/ i& U' `$ @- aThe appliance for purifying water is equipped with an UV lamp (with its accessories). The unit can be used with or without a constant water flowing (in accordance with the manual instructions). What should be the temperature of the water during the thermal tests?
+ @! k1 ~$ R6 }8 ]6 J) p: t- vDecision:
The applicable standard is IEC/EN 60335-1. The thermal tests have to be carried out according to clause 11 (heating) and clause 19 (abnormal conditions) of IEC/EN 60335-1. If according to the manual instructions the appliance can be used without water flowing, we have to consider this situation as worst case: all tests have to be performed without water flowing. At the

If the appliance is provided for use with water flowing only, the heating test (clause 11) shall be started with water at room temperature (25°C) but flowing. For the abnormal conditions test (clause 19), the water flowing has to be stopped unless there is a monitoring circuit to switch off the appliance in case of water
