This International Standard specifies the performance requirements for single-capped fluorescent lamps
for general lighting service.
The requirements of this standard relate only to type testing. Conditions of compliance, including methods
of statistical assessment, are under consideration.
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.
For some of the requirements given in this standard reference is made to “the relevant lamp data sheet”.
For some lamps these data sheets are contained in this standard. For other lamps, falling under the scope
of this standard, the relevant data are supplied by the lamp maunfacturer or responsible vendor.
