Lampholders for tubular fluorescent lamps and starterholders (IEC 60400:2017)

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.

Douilles pour lampes tubulaires à fluorescence et douilles pour starters (IEC 60400:2017)

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. La version française de cette norme n'a pas été soumise au vote.

Okovi za cevaste fluorescenčne sijalke in starterski okovi (IEC 60400:2017)

Ta dokument podaja tehnične in dimenzijske zahteve za okove za cevaste fluorescenčne sijalke in starterske okove ter preskusne metode, ki se uporabljajo za določevanje varne uporabe in prileganja sijalk okovom za sijalke in starterjev starterskim okovom. Ta dokument zajema neodvisne okove in okove za vgradnjo, ki se uporabljajo s cevastimi fluorescenčnimi sijalkami, opremljenimi z vznožki, kot je opredeljeno v dodatku A, ter neodvisne starterske okove in starterske okove za vgradnjo, ki se uporabljajo s starterji v skladu s standardom IEC 60155, namenjenimi za uporabo v izmeničnih krogotokih, katerih delovna napetost ne presega 1000 V RMS.
V tem dokumentu so zajeti tudi okovi za fluorescenčne sijalke z enim vznožkom, ki so vgrajeni v zunanjo lupino in kupolo, podobno kot okovi z Edisonovim navojem (npr. za sijalke z enim vznožkom G23 in G24). Takšni okovi za sijalke in žarnice so preskušeni na podlagi naslednjih točk in podtočk standarda 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 in 16.9.
Ta dokument zajema tudi okove, ki so del sijalk ali bodo vgrajeni v naprave. Zajema samo zahteve za okove za sijalke in žarnice. Za vse druge zahteve, kot je zaščita pred električnim udarom v območju terminalov, se uporabijo zahteve zadevnega standarda za naprave, ki se preskusijo po vgradnji v ustrezno opremo, ta oprema pa je preskušena po lastnem standardu. Okovi, ki so namenjeni zgolj uporabi proizvajalcev svetilk, niso namenjeni prodaji na drobno. Ta dokument se, kadar je to smiselno, uporablja tudi za okove za sijalke in starterske okove, ki niso izrecno omenjeni zgoraj, in za konektorje sijalk.
Kadar se v tem dokumentu uporablja izraz »okov«, se ta nanaša tako na okove za sijalke kot starterske okove.
Če se uporablja izraz »dvopolni okov za sijalke«, se ta nanaša tudi na okove za sijalke s klinastimi vznožki.

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

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.
