(Main)Luminaires - Part 2-24: Particular requirements - Luminaires with limited surface temperatures
Luminaires - Part 2-24: Particular requirements - Luminaires with limited surface temperatures
IEC 60598-2-24:2013 series specifies requirements for luminaires intended for use where the necessity of limited temperature on the outer surface exists, due to the risk of thermal effects, combustion or degradation of materials but where the risk of explosion in the atmosphere does not exist. The luminaires are for use with electric light sources on supply voltages not exceeding 1 000 V. This standard specifically excludes requirements for luminaires for use in explosive gas atmospheres and explosive dust atmospheres. This second edition cancels and replaces the first edition published in 1997. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) change of required degree of protection from IP6X to IP4X to harmonize with the international wiring rules;
b) temperature limits introduced for glass surface of any light source exposed to risk of dust.
This publication is to be read in conjunction with IEC 60598-1:2008.
Luminaires - Partie 2-24: Exigences particulières - Luminaires avec surfaces à températures limitées
La CEI 60598-2-24:2013, spécifie les exigences applicables aux luminaires prévus pour une utilisation qui nécessite de limiter la température de leurs surfaces extérieures, en raison du risque d'effets thermiques, de combustion ou de dégradation de matériaux, mais où le risque d'explosion dans l'atmosphère n'existe pas. Ces luminaires sont équipés avec des sources lumineuses électriques, pour des tensions d'alimentation ne dépassant pas 1000 V. La présente norme exclut spécifiquement les exigences pour les luminaires à utiliser dans des atmosphères gazeuses explosives et dans des atmosphères à poussières explosives. Cette deuxième édition annule et remplace la première édition parue en 1997. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) remplacement du degré de protection requis de l'IP6X à l'IP4X pour harmoniser avec les règles de câblage international.
b) des températures limites ont été introduites pour les surfaces vitrées de toutes les sources lumineuses exposées au risque de la poussière.
Cette publication doit être lue conjointement avec la CEI 60598-1:2008.

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 60598-2-24 has been prepared by subcommittee 34D: Luminaires,
of IEC technical committee 34: Lamps and related equipment.
This publication is intended to be read in conjunction with IEC 60598-1: Luminaires – Part 1:
General requirements and tests.
This second edition cancels and replaces the first edition published in 1997. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) change of required degree of protection from IP6X to IP4X to harmonize with the
international wiring rules;
b) temperature limits introduced for glass surface of any light source exposed to risk of dust.

Part 2-24: Particular requirements –
Luminaires with limited surface temperatures
24.1 Scope
This part of the IEC 60598 series specifies requirements for luminaires intended for use where
the necessity of limited temperature on the outer surface exists, due to the risk of thermal
effects, combustion or degradation of materials but where the risk of explosion in the
atmosphere does not exist. The luminaires are for use with electric light sources on supply
voltages not exceeding 1 000 V.
This standard specifically excludes requirements for luminaires for use in explosive gas
atmospheres and explosive dust atmospheres.
24.2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments)
