    Abstract - (Show below) - (Hide below)

    Applies to built in and independent single phase transformers with separate input and output windings for use on a.c. supply up to 1,000 V to 50 Hz or 60 Hz, to stabilise and supply cold cathode tubular lamps (or assemblies of such lamps) having a no load rated output voltage over 1,000 V but not over 10,000 V and meant for electric advertising signs, lighting, light signals and similar purposes. Does not apply to auto transformers and electronic convertors. May serve as a guide for transformers with applications other than those specified in the scope, such as instance transformers for photographic lamps, as long as they are not the subject of a particular IEC standard and their characteristics remain within the framework of those specified in the scope.
