scope:

States the technical and dimensional requirements for lampholders for tubular fluorescent 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 for building-in, used with tubular fluorescent lamps provided with caps as listed in annex A, and independent starterholders and starterholders for building-in, used with starters in accordance with IEC 155, 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 fluorescent lamps integrated in an outer shell and dome similar to Edison screw lampholders (e.g. for G23 and G24 capped lamps). As far it applies, this standard also covers combinations of lampholders and starterholders as well as lampholders or combinations which are wholly or partly integral with the luminaire . It also applies, as far as reasonable, to lampholders and starterholders other than the types explicitly mentioned above and to lamp connectors.
