Specifies general safety requiremetns for approval and test purposes for transformers for toys. This Standard is an adoption with national modifications and cotnains the full text of IEC 61558-2-7:1997.

Replacement:This part 2 of IEC 61558 AS/NZS 61558 applies to transformers for toys having a rated supply voltage not exceeding 250 V a.c., a rated frequency of 50/60 Hz, a rated output voltage not exceeding 24 V a.c. or 33 V ripple-free d.c. and a rated output not exceeding 200 VA and a rated output current not exceeding 10 A.This standard does not in general take into account playing with the transformer by children.
