0 I; `& S; p' W; mQuestion: The appliance for purifying water is equipped with an UV lamp (with its
3 G4 W* J7 W/ k- z" caccessories). The unit can be used with or without a constant water flowing (in
; x% T! w$ u3 q0 d8 G" M% l0 daccordance with the manual instructions). What should be the temperature of
the water during the thermal tests?
0 u; `. S$ X3 ~6 }, S4 f. PDecision: 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
! R: }7 D  H, m7 V2 Q, ~conditions) of IEC/EN 60335-1. If according to the manual instructions the
1 P% n( W3 m  f1 p0 ?appliance can be used without water flowing, we have to consider this situation
" a& I" p$ C* u! g4 _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
5 B5 \" j  m# y, O- f: m  _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).
