DSH 594

Discontinuous disturbances producted by a steam iron with boiler station.

7.3.4.11

CISPR 14-1(ed.4);am1;am2

Question:
How to consider the case of a steam iron with boiler station concerning the test of discontinuous interferences CISPR14-1:2002? :
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.
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.
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 ?
Proposal:
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).
