Lamp controlgear. Particular requirements for ballasts for fluorescent lamps | Status: Current, Superseded

1 Scope This part of IEC 61347 specifies safety requirements for ballasts, excluding resistance types, for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with fluorescent lamps with or without pre-heated cathodes operated with or without a starter or starting device and having rated wattages, dimensions and characteristics as specified in IEC 60081 and 60901. This standard applies to complete ballasts and to their component parts such as reactors, transformers and capacitors. Particular requirements for thermally protected ballasts are given in annex B. Ballasts for conventional operation of lamps at mains frequency are covered, while a.c. supplied electronic ballasts for high frequency operation are excluded. These are specified in IEC 61347‑2‑3. Capacitors having a capacitance greater than 0,1 µF are covered by IEC 61048 and IEC 61049. Capacitors having a capacitance less than or equal to 0,1 µF are specified in IEC 60384‑14. Performance requirements are the subject of IEC 60921.
