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.
IEC 60598-2-20 has been prepared by subcommittee 34D: Luminaires, of IEC technical
committee 34: Lighting. It is an International Standard.
This fifth edition cancels and replaces the fourth edition published in 2014. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) specific provisions for temporarily installed protected lighting (TPL) chains have been
added;
b) new terms and definitions have been added.

described in greater detail at www.iec.ch/standardsdev/publications.
This Part 2-20 is to be used in conjunction with the latest edition of IEC 60598-1 and its
amendment(s). It was established on the basis of the ninth edition (2020) of that standard.
NOTE 1 When "Part 1" is mentioned in this document, it refers to IEC 60598-1.

be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be

INTRODUCTION
This new edition includes the following technical changes:
a) Inclusion of specific provisions for temporarily installed protected lighting (TPL) chains.
This form of lighting chain was not previously addressed with specific provisions in previous
editions of the standard. A temporarily installed protected lighting chain is a physical impact
protected rough service lighting chain intended for temporary installation on building sites
during the construction or demolition phases of a building project.
b) Addition of terms and definitions
New terms and definitions have been added to include the expanded typology for lighting chains
and to include a connector with breaking capacity (CBC).
c) Inclusion of graphical depictions of lighting chains
Graphical depictions have been added to clarify and differentiate the construction and
installation configurations of the various different types of lighting chains. Word descriptions
alone had limitations in clearly and precisely defining the characteristics of the numerous
variants in this luminaire sector.
The illustrations show the three main types of lighting chains: permanently installed lighting
chains, temporarily installed lighting chains and temporarily installed protected lighting (TPL)
chains, as well as further differentiating by installation and/or fixing method where applicable.

LUMINAIRES –
Part 2-20: Particular requirements – Lighting chains

20.1 Scope
This part of IEC 60598 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.
Lighting chains provided with fixed or detachable attachments for example ornamental or
decorative, are considered to be covered by this document.
For lighting chains fitted with lampholders of the push-in type, the appropriate requirements of
this document applies.
This document covers the following lighting chains:
a) permanently installed lighting chains;
b) temporarily installed lighting chains;
c) temporarily installed protected lighting (TPL) chains.
NOTE 1 Festoon lighting chain – a lighting chain that is supported by the supply cable or fixed at the lampholder
and is permanently connected to the fixed wiring. Festoon lighting chains are primarily suitable for permanent indoor
or outdoor lighting applications.
NOTE 2 Decorative lighting chain – a lighting chain that is supported by the supply cable and is temporarily
connected to the fixed wiring. Decorative lighting chains are primarily suitable for domestic, indoor or indoor/outdoor
temporary lighting applications, see Figure 1 for examples.
NOTE 3 Temporarily installed protected lighting (TPL) chain – a lighting chain where each lampholder is fixed to
the building or structure and the light source is enclosed by a protective enclosure and is temporarily connected to
the fixed wiring. Temporarily installed protected lighting chains are primarily suitable for use in rough service lighting
applications.
For lighting chains with non-standardized lamps (e.g. lamps of the push-in type) the lamps are
regarded as a part of the lighting chain and consequently included in the testing.
NOTE 4 For products where the lighting chain is permanently fixed to a frame or pre-lit Christmas tree the relevant
clauses of IEC 60598-2-4 can also apply.
NOTE 5 In some countries the term "strings" is used instead of "chains".
NOTE 6 Candlestick luminaries are tested according to IEC 60598-2-4.
20.2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies.
For undated references, the latest edition of the referenced document (including any
amendments) applies.
