Endurance and thermal tests on apliances for purifying water usig an UV lamp

11-19 / 12

60335-1(ed.3) & 60335-1(ed.4) & 60598-1(ed.5) & EN 60335-1:1994 & EN 60335-1:2002 & EN 60598-1:2000

Question:
The 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?
Decision:
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
beginning of the tests, the water shall be at room temperature (25°C). 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
flow interruption. At the beginning of the test the water shall be at room temperature (25°C).
