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 60317-0-8 has been prepared by IEC technical committee 55:

3.2.1 Methods of test
All methods of test to be used for this standard are given in the IEC 60851 series.
The clause numbers used in this standard are identical with the respective test numbers in the
IEC 60851 series.
In case of inconsistencies between the IEC 60851 series and this standard, IEC 60317-0-8

to all nominal conductor dimensions covered by the specification sheet.
Unless otherwise specified, all tests shall be carried out at a temperature from 15 °C to 40 °C
and a relative humidity from 45 % to 75 %. Before measurements are made, the specimens

shall be preconditioned under these atmospheric conditions for a time sufficient to allow the
specimens to reach stability.
The wire to be tested shall be removed from the packaging in such a way that the wire will not
be subjected to tension or unnecessary bends. Before each test, sufficient wire should be
discarded to ensure that any damaged wire is not included in the test specimens.

When reference is made to a winding wire according to a standard in the IEC 60317 series,
the following information is included in the description:

___________
1)
For thicknesses over 5,60 mm up to and including 10 mm and for widths over 16 mm up to and including 25 mm
where, for technical reasons additional sizes may be needed, the R 40 series shall be used. The ratio
