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 60598-2-20 has been prepared by subcommittee 34D: Luminaires,
of IEC technical committee 34: Lamps and related equipment
This third edition cancels and replaces the second edition published in 1996, its Amendment 1
(1998), its Amendment 2 (2002) and the interpretation sheets of March 2001 (1) and July 2003

changes relating to 20.7.15. This third edition constitutes a minor revision.
This publication is intended to be read in conjunction with IEC 60598-1: Luminaires – Part 1:
General requirements and tests. It was established on the basis of the seventh edition (2008)
of that standard.

Part 2-20: Particular requirements –
Lighting chains
20.1 Scope
This part of IEC 60598 specifies requirements for lighting chains fitted with series- or parallel-
or a combination of series/parallel-connected incandescent lamps for use either indoors or
outdoors on supply voltages not exceeding 250 V.
NOTE 1 A Christmas tree chain is an example of a lighting chain fitted with series or series/parallel connected lamps.
A chain for illuminating ski-tracks or promenades is an example of a lighting chain fitted with parallel connected
lamps.
NOTE 2 For lighting chains fitted with lampholders of the push-in type, the appropriate requirements of this part of
IEC 60598 apply.
NOTE 3 In some countries, the term "strings" is used instead of "chains".
NOTE 4 For lighting chains with non-standardised 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 (and thereby in the certificate, if any).
20.2 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest editi
