Lampholders for tubular fluorescent lamps and starterholders
IEC 60400:2017 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 eighth edition cancels and replaces the seventh edition published in 2008, Amendment 1:2011 and Amendment 2:2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- alignment with ISO/IEC drafting rules;
- renumbering of clauses, tables and figures.
This bilingual version (2017-12) corresponds to the monolingual English version, published in 2017-06.
The French version of this standard has not been voted upon.
Douilles pour lampes tubulaires à fluorescence et douilles pour starters
L'IEC 60400:2017 fixe les exigences techniques et dimensionnelles auxquelles doivent satisfaire les douilles pour lampes tubulaires à fluorescence et les douilles pour starters, ainsi que les méthodes d'essai à utiliser pour déterminer le degré de sécurité et le montage correct des lampes et des starters dans leurs douilles respectives.
Cette huitième édition annule et remplace la septième édition publiée en 2008, l’Amendement 1:2011 et l’Amendement 2:2014. Cette édition constitue une révision technique.
Cette édition comprend les changements techniques importants suivants par rapport à l'édition précédente:
- alignement avec les règles de rédaction ISO/IEC;
- renumérotation des articles, des tableaux et des figures.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
