This document 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 document covers independent lampholders and 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 60155, intended for use in AC circuits where the working voltage does not exceed 
1 000 V r.m.s. 
This document 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). Such lampholders are tested in accordance with the following clauses 
and subclauses of IEC 60238: 9.4; 9.5; 9.6; 10.3; 11.7; 12; 13.2; 13.5; 13.6; 13.7; 14; 16.3; 16.4; 16.5 and 16.9. 
This document 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 applicable and tested after building into the appropriate equipment, when that equipment is tested according to its own standard. Lampholders for use by luminaire manufacturers only are not for retail sale. 
This document also applies, as far as is reasonable, to lampholders and starterholders other than the types explicitly mentioned above and to lamp connectors. 
Where the term "holder" is used in this document, both lampholders and starterholders are 
intended. 
Where the term “bi-pin lampholder” is used, lampholders for wedged caps are also intended.dition 8.1 2020-02 CONSOLIDATED VERSION VERSION CONSOLIDéE colour inside Lampholders for tubular fluorescent lamps and starterholders Douilles pour lampes tubulaires à fluorescence et douilles pour starters IEC 60400:2017-06+AMD1:2020-02 CSV(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2020 IEC, Geneva, Switzerland All rights reserved.
