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

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 ----------------------

10 times at 25 °C ± 2 °C
– for rope lights having an IP number over X0
10 times at 25 °C ± 2 °C followed by 10 times at –15 °C ± 2 °C

Before the low temperature tests the pipe is kept for 16 h in the low temperature cabinet

at a temperature of –15 °C ± 2 °C.

4) After test 3), with the test specimen at room temperature, the pipe is wound on a

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.

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

side in a suitable low temperature cabinet and maintained there for at least 16 h at a

temperature of –15 °C ± 5 °C.
