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 60598-2-21 has been prepared by subcommittee 34D: Luminaires,
of IEC technical committee 34: Lamps and related equipment.The text of this standard is based on the following documents:
FDIS Report on voting
34D/1146/FDIS 34D/1154/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

be found on the IEC website.In this standard, the following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
The committee has decided that the contents of this publication will remain unchanged until the
stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to
the specific publication. At this date, the publication will be• reconfirmed,

NOTE 2 For products where the rope light is fixed to a frame or the like as ornaments like Santa Claus, snowman
and similar, relevant clauses of IEC 60598-2-4 and/or IEC 60598-2-7 can also apply.
Rope lights provided with, fixed or detachable, extra attachments of different kinds, e.g.
ornamental element in temporary decorative configurations due to festivals, celebrations, etc.
or in two or three dimensional reproductions of persons or animals (real or imaginary) are
considered to be covered by this standard.21.2 Normative references

tests carried out in turn.1) A pull of 60 N, the stress being applied to the ends of the pipe, 45 times without jerks,
each time for 1 s.2) A torque of 0,15 Nm, the stress being applied to the ends of the pipe in the most
unfavorable direction (alternatively in cases of doubt) without jerks for 1 min.During and after the above test tests, the conductors shall not have moved noticeably in the
terminals and the pipe shall not be damaged.b) For flexible rope lights, compliance is checked by the tests of 1) and 2) above followed by
the additional tests 3) and 4) below.3) Wind the pipe in full test length (1 m) on a cylinder of 150 mm diameter with a pull of
60 N for the number of operations and at the ambient temperature given below:---------------------- Page: 11 ----------------------

mandrel of between 4 and 5 times the diameter of the test piece and then is placed in
the low temperature cabinet (-15 °C ± 2 °C) for 16 h.After this time period the sample is wound around the mandrel for two turns in the
cabinet.There shall be no cracks.

c) For rigid and flexible rope lights compliance is checked by subjecting the pipe to the
following impact test at low temperature.Three pieces of the complete rope light each having a length at least five times the
diameter of the rope light with a minimum of 150 mm is taken and subjected to the following
test.– The apparatus according to Figure 3 and the test pieces to be tested are placed side by
