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
# v- ^0 {6 x3 ~% u9 dappliance 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
% s$ E, q( l; K- e$ U7 L* m, Lbeginning 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
