Ballasts for tubular fluorescent lamps. Performance requirements
适用范围：This standard specifies performance 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 tubular fluorescent lamps with 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. It applies to complete ballasts and their component parts such as resistors, transformers and capacitors. A.C. supplied electronic ballasts for tubular fluorescent lamps for high frequency operation specified in IEC 61347-2-3 are excluded from the scope of this standard. NOTE In some regions there are laws on EMC for luminaires. The controlgear also contributes to this EMC behaviour. See Bibliography for further references.
