This International Standard states the technical and dimensional requirements for lampholders for tubular flourescent lamps and for starterholders, and the methods of test to be used in determining the safety and the fit of the lamps in the lampholders and the starters in the starterholders.


This standard covers independent lampholders and lampholders for building-in, used with tubular flourescent lamps provided with caps as listed in Annex A, and independent starterholders and starterholders for building-in, used with starters in accordance with IEC 60155, intended for use in a.c. circuits where the working voltage does not exceed 1000 V r.m.s.


This standard also covers lampholders for single-capped tubular flourescent lamps integrated in an shell and dome similar to Edison screw lampholders (e.g. for G23 and G24 capped lamps). Such lampholders are tested in accordance with the following clauses and sub clauses of IEC 60238: 8.4; 8.5; 8.6; 9.3; 10.7; 11; 12.2; 12.5; 12.6; 12.7; 13; 15.3; 15.4; 15.5 and 15.9.


This standard also covers lampholders which are integral with a luminaire or intended to be built into appliances. It covers the requirements for the lampholder only. For all other requirements, such as protection against electric shock in the area of the terminals, the requirements of the relevant appliance standard are to be observed and tested after building into the appropriate equipment, when that equipment is testes according to its own standard. Lampholder for use by luminarie manufacturers only are not for retail sale.


This standard also applies, as far as is reasonable, to lampholders and starterholders other than the types explicity mentioned above and to lamp connectors.


Where the term "holder" is used in the standard, both lampholders and starterholders are intended.
