This amendment has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances.
The text of this amendment is based on the following documents:
FDIS Report on voting
61/5364/FDIS 61/5392/RVD
Full information on the voting for the approval of this amendment can be found in the report
