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.
