Luminaires - Part 1: General requirements and tests

IEC 60598-1:2014 specifies general requirements for luminaires, incorporating electric light sources for operation from supply voltages up to 1 000 V. The requirements and related tests of this standard cover: classification, marking, mechanical construction, electrical construction and photobiological safety. This eighth edition cancels and replaces the seventh edition published in 2008. This edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition:
a) requirements to support the construction methods for new LED luminaires entering the market;
b) photobiological requirements extended;
c) more precise requirements for insulation between different types of electrical circuit;
d) other general updates and improvements. The contents of the corrigenda of October 2015, of December 2015, of May 2017 and interpretation sheet 1 of May 2016 have been included in this copy.

Luminaires - Partie 1: Exigences générales et essais

L'IEC 60598-1:2014 spécifie pour les luminaires incorporant des sources lumineuses électriques, les exigences générales pour le fonctionnement à des tensions d'alimentation jusqu'à 1 000 V. Les exigences et les essais correspondants de cette norme concernent: la classification, le marquage, la construction mécanique et électrique. Cette huitième édition annule et remplace la septième édition parue en 2008. Cette édition constitue une révision technique et inclue les changements techniques significatifs suivants par rapport à l'édition précédente:
a) exigences pour aider aux méthodes de construction des nouveaux luminaires à LED entrant sur le marché;
b) exigences photobiologiques étendues;
c) exigences plus précises concernant l'isolation entre les différents types de circuits électriques;
d) autres mises à jour générales et améliorations. Le contenu des corrigendas d'octobre 2015, de décembre 2015, de mai 2017 et la feuille d'interprétation 1 de mai 2016 a été pris en considération dans cet exemplaire.

Full information on the voting for the approval of this interpretation sheet can be found in the

report on voting indicated in the above table.
___________
INTRODUCTION (not part of the proposal)

Changes introduced in IEC 60598-1 Ed.8.0 were made urgently to address completely new

designs of LED luminaire that are entering the market. Some further alignment with the

already existing previous requirements of the standard are still needed and this will be

addressed for Amendment 1 to Edition 8 that is now in preparation.
PROPOSAL

To publish Interpretation Sheet on Clause 4.31; Clause 10; Clause 11; Annex M and Annex X

of IEC 60598-1:2014 (Ed. 8.0), Luminaires – Part 1: General requirements and tests, as

INTERPRETATION SHEET
Clause 4.31; Clause 10; Clause 11; Annex M and Annex X of
IEC 60598-1:2014 (Ed. 8.0), Luminaires – Part 1: General requirements and tests

For insulation requirements between active (current carrying/live) parts and accessible parts,

Table X.1 of Annex X is to be taken as the definitive reference of the required insulation that

is to be provided. Furthermore, the details prescribed by Table X.1 are to be used as the

basis for establishing the ‘working voltage’ that is to be considered for application of the

electric strength tests of Clause 10 and Creepage and Clearance requirements of Clause 11.
