How to consider the case of a steam iron with boiler station concerning the test of discontinuous interferences CISPR14-1:2002? :* v8 P- a: H) {2 M6 H0 j& c' O
The clause 7.3.4.11 defines the testing conditions for irons (dry or steam), but there are no precisions regarding the boiler part actuated manually. ! d- f/ F/ x0 d; H2 QThe standard defines in clause 4.2.3.1 that individual switching operations are generally not taken into account for this test, and gives requirements in clauses 7.2.3 & 7.3.2.4 of specific apparatus for which repetitive switching manual operations are taken into consideration (sewing machines, calculating machines, soldering equipment, etc. ). But nothing is said about steam boiler station of iron.# B- _4 f* _# d+ d" U* a" O" [( n, G
Do we have to apply strictly the standard (only clause 7.3.4.11) or to test the boiler station with a cycle of manual operation for steam generation ?% x8 d3 ~' g3 ^: N& m' s3 u
Proposal: 9 g: n' w- ^* gThis appliance has to be test with iron settled at the max temperature (worst case and according sub-clause 7.3.4.11), boiler switched on and making 10 second of steam production and 10 second of stand by (according to normal use stated in IEC 60335.2.3).& z1 s1 i* z& @& G s3 D) e
