This part of 61347 specifies particular safety requirements for starting devices (starters other than glow starters and ignitors) for fluorescent and other discharge lamps for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz which produce starting pulses not greater than 100 kV and which are used in combination with lamps and ballasts covered in IEC 60081, 60188, 60192, 60662, 60901, 61167, 61195, 61199, 61347-2-8 and 61347-2-9. It does not apply to glow starters or starting devices which are incorporated in discharge lamps or which are manually operated. Preheat transformers for fluorescent lamps are covered by IEC 61347-2-8. This standard refers only to starting devices for use with ballasts and lamps which are internationally the most in demand. Performance requirements are given in IEC 60927.
