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.
La présente version bilingue (2017-12) correspond à la version anglaise monolingue publiée en 2017-06.

LAMPHOLDERS FOR TUBULAR FLUORESCENT
LAMPS AND STARTERHOLDERS
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-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60400 has been prepared by subcommittee 34B: Lamp caps and

holders, of IEC technical committee 34: Lamps and related equipment.
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:
a) alignment with ISO/IEC drafting rules;
b) renumbering of clauses, tables and figures.

This bilingual version (2017-12) corresponds to the monolingual English version, published in

2017-06.
The text of this International Standard is based on the following documents:

LAMPHOLDERS FOR TUBULAR FLUORESCENT
LAMPS AND STARTERHOLDERS
1 Scope

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.
