Question:
% `7 W, v- Y; [0 A5 X2 n8 F, QHow to consider the case of a steam iron with boiler station concerning the test of discontinuous interferences CISPR14-1:2002? :
5 t$ v* ?1 T. Y3 KThe 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.( g5 E- e4 @$ ^: z4 J4 ?% 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.
3 F/ O  l) G7 X9 HDo 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 ?
! H% L. s7 f# P- i6 sProposal:4 ]4 t4 o- o6 S) [" p$ H
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).3 `+ r( [5 n1 n7 r& a1 \
