Question:
# ]! T4 Z# l( E+ E7 M. m6 C$ ^+ lHow to consider the case of a steam iron with boiler station concerning the test of discontinuous interferences CISPR14-1:2002? :: G' n% X/ k( w6 W! j1 E2 a7 r2 I
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.7 a' G0 u4 p, @# B9 i8 ]$ k* H' @
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.
! C# y! w1 ^8 D5 j3 H9 ODo 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 ?
7 o- S! p, O) f! iProposal:/ n$ g/ d# U' o7 M( ^  \8 ]
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)./ g$ W# o, z: U+ q
