Question:
% D' s2 |% s1 p) C0 bHow to consider the case of a steam iron with boiler station concerning the test of discontinuous interferences CISPR14-1:2002? :
5 M/ U6 D/ C( g  R' tThe 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.3 t1 |( v/ z# t1 r# o. J* X  U3 L
The 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.; m4 N% I' K- T$ P% N3 i
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 ?# c1 f! R9 T% ?0 u$ \- H" s, l. ^+ S
Proposal:- q9 n! q! x( {
This 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).
