This standard covers ballasts, excluding resistance types, for use on a.c. supplies up to 1000 V at 50 Hz or 60 Hz, associated with tubular 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 Publication 81. It applies to complete ballasts and to their component parts such as reactors, transformers and capacitors. Particular requirements for thermally protected ballasts are given in Appendix B. This standard also specifies ballasts for lamps which are not yet fully standardized. Ballasts for conventional operation of lamps at mains frequency are covered. A.C. supplied electronic ballasts for high frequency operation are excluded. These are specified in IEC Publication 928. Capacitors having a capacitance greater than 0.1 Âµ f are covered by IEC Publication 566. Capacitors having a capacitance less than or equal to 0.1 Âµ F are specified in IEC Publication 384-14.
