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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60189-3 has been prepared by subcommittee 46C: Wires and
symmetrical cables, of IEC technical committee 46: Cables, wires, waveguides, r.f.
connectors, r.f. and microwave passive components and accessories.
This fourth edition cancels and replaces the third edition published in 1988 and amendment 1
(1989). This edition constitutes a technical revision.
This edition includes an update of the technical characteristics.

LOW-FREQUENCY CABLES AND WIRES
WITH PVC INSULATION AND PVC SHEATH –
Part 3: Equipment wires with solid or stranded conductor wires,
PVC insulated, in singles, pairs and triples
1 Scope
This part of IEC 60189 is applicable to equipment wires with solid or stranded conductor,
polyvinyl chloride (PVC) insulated, in singles, pairs and triples to be used for internal wiring of
telecommunication equipment, industrial and consumer electronic equipment.
NOTE It is the responsibility of the manufacturer to establish quality assurance by quality control procedures which
will ensure that the product will meet the requirements of this standard. It is not intended that a complete testing
programme must be carried out on every length of conductor. When the purchaser wishes to specify acceptance
tests or other quality procedures, it is essential that agreement be reached between the purchaser and the
manufacturer by the time of ordering.
