scope:

This Standard specifies the performance requirements for single-capped fluorescent lamps for general lighting service. The requirements of this standard relate only to type testing. The following lamp types and modes of operation with external ballasts are included: a) lamps operated with an internal means of starting, having preheated cathodes, for operation on a.c. mains frequencies; b) lamps operated with an external means of starting, having preheated cathodes, for operation on a.c. mains frequencies with the use of a starter, and additionally operating on high frequency; c) lamps operated with an external means of starting, having preheated cathodes, for operation on a.c. mains frequencies without the use of a starter (starterless), and additionally operating on high frequency; d) lamps operated with an external means of starting, having preheated cathodes, for operation on high frequency; e) lamps operated with an external means of starting, having non-preheated cathodes, for operation on high frequency.
