Transformers for tubular discharge lamps having a no-load output voltage exceeding 1000 V (generally called neon-transformers) - General and safety requirements
Standards Australia
Specifies general and safety requirements for single-phase transformers with separate input and output windings, for use on an a.c. supply up to 1000 V at 50/60 Hz and having a no-load output voltage exceeding 1000 V but not exceeding 10 000 V and intended for the supply of cold cathode lighting for electric advertising signs, light signals and similar purposes. This Standard is identical with and has been reproduced from IEC 1050:1991, including Corrigendum 1:1992 and Amendment 1:1994.

This International Standard is applicable to independent and built-in single-phase transformers with separate input and output windings, for use on a.c. supply up to 1 000 V at 50 Hz or 60 Hz, to supply and stabilize cold cathode tubular lamps (or assemblies of such lamps) having a no-load rated output voltage exceeding 1 000 V but not exceeding 10 000 V (see notes 1 and 2) and intended for lighting and for electric advertising signs, light signals and similar purposes.
NOTE - Different requirements apply in Japan and North America, which will be the subject of a future annex to this standard.
In order to ensure the safety of these transformers, it is necessary to check their performance. But since no standardization of the characteristics of these lamps exists, reference loads are defined in this standard to ensure reproducible test results.
In locations where special conditions prevail, as in ships, vehicles and the like, and in dangerous locations, for example, where explosions are liable to occur, special constructions may be required.
This standard does not apply to transformers intended for the supply of lamps or tubes such as low-pressure or high-pressure sodium vapour lamps, high-pressure mercury vapour lamps, halogen lamps, xenon lamps, hot cathode tubular fluorescent lamps, special lamps for document copying machines, etc.
This standard does not apply to auto-transformers and electronic convertors.
This standard may, nevertheless, serve as a guide for transformers with applications other than those specified in the scope, for instance transformers for photographic lamps, as long as their characteristics remain within the framework of those specified in the scope and they are not the subject of a particular IEC standard.
Capacitors shall comply with IEC 1048, where applicable.
