This part of the IEC 61347 series specifies particular safety requirements for electromagnetic controlgear for discharge lamps such as high-pressure mercury vapour, low-pressure sodium vapour, high-pressure sodium vapour and metal halide lamps. The standard covers inductivetype electromagnetic controlgear for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with discharge lamps, having rated wattages, dimensions and characteristics as specified in IEC 60188, IEC 60192 and IEC 60662. This standard applies to complete electromagnetic controlgear and to their component parts such as reactors, transformers and capacitors. Particular requirements for thermally protected electromagnetic controlgear are given in Annex B. For certain types of discharge lamps, an ignitor is required. NOTE Electromagnetic controlgear for fluorescent lamps are covered by IEC 61347-2-8. Performance requirements are the subject of IEC 60923.
