- C" g+ B$ R0 u! b s+ lHow to consider the case of a steam iron with boiler station concerning the test of discontinuous interferences CISPR14-1:2002? :
5 ?! H4 s ]* K% o& |/ zThe 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.: \* Q! r# B* m, S7 j+ o1 u/ {
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.
# P: Q! S, F$ G( _6 \5 Q, c) rDo 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 ?

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).
