This part of IEC 60598 applies to luminaires for cold cathode tubular discharge lamps and similar equipment@ operating on a no-load rated output voltage over 1 000 V but not exceeding 10 000 V@ mainly used for general lighting@ for indoor or outdoor applications and for supply voltages up to 1 000 V. NOTE In Japan@ the output voltage of 15 000 V is acceptable. It covers luminaires incorporating luminous-discharge tubes and supply units@ of fixed or portable type@ supplied by high@ mains or ELV voltages by transformers@ inverters or converters. This standard does not cover luminaires for luminous-discharge tubes operating at rated voltages not exceeding 1 000 V (pre-heated cathodes)@ for which reference is made to the relevant part 2 of IEC 60598@ and luminous discharge tube luminaires to be assembled in site as an electrical lighting system@ for which regional wiring rules apply. This standard is read in conjunction with those sections of Part 1 to which reference is made.
