Specifies safety requirements for electronic ballasts for tubular fluorescent lamps for use on a.c. supplies up to 1000 volt at 50 or 60 Hz with operating frequencies deviating from the supply frequency.

This standard specifies general and safety requirements for electronic ballasts for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz with operating frequencies deviating from the supply frequency, associated with tubular fluorescent lamps as specified in IEC 60081 and other tubular fluorescent lamps for high-frequency operation.Particular requirements for electronic ballasts with means of protection against overheating are given in annex B.Particular requirements for a.c./d.c. supplied electronic ballasts for maintained emergency lighting are given in annex C.
