36、y and stabil- ize cold cathode tubular lamps (or assemblies of such lamps) having a no-load rated output voltage exceeding 1 o00 V but not exceeding 10 o00 V (see notes 1 and 2) and intended for lighting an for electric advertising signs, light signais and similar purposes. In order to ensure the sa
37、fety of these transformers, it is necessary to check their performance. But since no standardization of the character- istics 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
38、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
39、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 conver- tors. This standard may, nevertheless, serve as a guide for transformers with applications other
40、 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. BSI B
