IEC 60598-2-20:2014
(Main)Luminaires - Part 2-20: Particular requirements - Lighting chains
Luminaires - Part 2-20: Particular requirements - Lighting chains
IEC 60598-2-20:2014 specifies requirements for lighting chains fitted with series, parallel or a combination of series/parallel connected light sources for use either indoors or outdoors on supply voltages not exceeding 250 V. For combinations where rope lights (also known as sealed lighting chains) are included, see IEC 60598-2-21. This fourth edition cancels and replaces the third edition (2010). This edition includes the following significant technical changes with respect to the previous edition, where the requirements for rope lights (sealed lighting chains) have been removed and are now dealt with in IEC 60598-2-21. The contents of the corrigendum of December 2016 have been included in this copy.
This publication is to be read in conjunction with IEC 60598-1:2014
Luminaires - Partie 2-20: Exigences particulières - Guirlandes lumineuses
L'IEC 60598-2-20:2014 spécifie les exigences applicables aux guirlandes lumineuses munies de sources lumineuses montées en série, en parallèle ou en combinaison série/parallèle pour emploi à l'intérieur ou à l'extérieur, pour des tensions d'alimentation ne dépassant pas 250 V. Pour les combinaisons contenant des cordons lumineux (également appelés guirlandes lumineuses scellées), voir l'IEC 60598-2-21. Cette quatrième édition annule et remplace la troisième édition (2010). Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente. La principale modification est le retrait des exigences concernant les cordons lumineux (guirlandes lumineuses scellées), ces exigences étant à présent traitées dans l'IEC 60598-2-21. Le contenu du corrigendum de décembre 2016 a été pris en considération dans cet exemplaire.
Cette publication doit être lue conjointement avec la CEI 60598-1:2014.

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 sub
