EN 60598-2-24:2013

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.

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.

Overview

EN 60598-2-24:2013 (CLC adoption of IEC 60598-2-24:2013) is the European particular requirements standard for luminaires with limited surface temperatures. It applies to electric luminaires for supply voltages up to 1 000 V where restricting outer-surface temperature is necessary to avoid thermal effects, ignition or material degradation - excluding atmospheres where explosive gas or dust risks exist. This second edition replaces the earlier 1997/1998 edition and aligns with updated international wiring and dust-safety provisions.

Key topics and technical requirements

• Scope and exclusions: Covers luminaires intended to limit surface temperature; expressly excludes luminaires for explosive gas or dust atmospheres.
• Classification by dust environment: Defines suitability for locations with (a) no unusual dust accumulation, (b) accumulation of non‑conductive dust, and (c) accumulation of conductive dust.
• Degree of protection (IP rating):
  • Minimum enclosure protection IP4X as harmonized with wiring rules.
  • IP5X required where dust presence is expected.
  • IP6X required for environments with conductive dust (or where wiring rules demand higher protection).
• Temperature limits & tests:
  • Endurance and thermal tests reference EN/IEC 60598-1 test procedures with specific limits for normal, abnormal and fault conditions.
  • New in this edition: temperature limits for glass surfaces of light sources that could be exposed to dust.
• Construction and marking:
  • Surfaces likely to collect dust and any surface wider than 7.5 mm must meet horizontal-surface temperature limits; vertical surfaces have defined exceptions.
  • Luminaires must carry the specific symbol for “limited surface temperatures” and manufacturer literature must state intended location/classification.
• Referenced safety aspects: Creepage/clearances, earthing, terminals, insulation resistance and resistance to heat/fire/tracking as applied from EN/IEC 60598-1.

Practical applications and users

This standard is used by:

• Luminaire manufacturers and product designers seeking to design fixtures safe for heat-sensitive environments.
• Test laboratories and certification bodies performing endurance and thermal tests for compliance.
• Specifiers, installers and safety engineers selecting luminaires for areas where outer-surface temperature control is critical (e.g., near combustible materials or where dust accumulation may occur).
• Regulatory compliance teams responsible for CE marking and LVD conformity.

Keywords: EN 60598-2-24:2013, luminaires with limited surface temperatures, limited surface temperature standard, IEC 60598-2-24, IP4X IP5X IP6X, thermal limits for luminaires.

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 accur
