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 60317-0-1 has been prepared by IEC technical committee 55:
Winding wires.
This third edition cancels and replaces the second edition published in 1997, its amendment 1
(1999), and its amendment 2 (2005) and constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
– addition of Grade 3 minimum insulation increases and maximum overall diameters for wires
up to 0,071 mm nominal conductor diameter in Tables 1 and A.1;
– revisions to minimum increase in bonding layer for wires up to 0,100 mm nominal conductor
diameter in Tables 2 and A.2;
– addition of Grade 3 dielectric breakdown requirements for wires up to 0,071 mm nominal
conductor diameter;

This standard is to be read in conjunction with the IEC 60851 series. The clause numbers used
in this part of IEC 60317 are identical with the respective test numbers of IEC 60851.
In case of inconsistencies between IEC 60851 and this part of IEC 60317, the latter shall
prevail.

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.
A list of all parts of the IEC 60317 series, under the general title Specifications for particular
types of winding wires, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result 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

INTRODUCTION
This part of IEC 60317 is one of a series which deals with insulated wires used for windings in
electrical equipment. The series has three groups describing:
1) winding wires – Test methods (IEC 60851);
2) specifications for particular types of winding wires (IEC 60317);
3) packaging of winding wires (IEC 60264).

3.2 General notes on methods of test
All methods of test to be used for this part of IEC 60317 are given in the IEC 60851 series.
Where no specific range of nominal conductor diameters is given for a test, the test applies to
all nominal conductor diameters covered by the specification sheet.
Unless otherwise specified, all tests shall be carried out at a temperature from 15 °C to 35 °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.
3.3 Appearance
The film coating shall be essentially smooth and continuous, free from streaks, blisters and
foreign material when examined with normal vision, as wound on the original spool or reel.
When agreed upon between the user and supplier, examination using 6× to 10× magnification
shall be used for wires with a nominal diameter less than 0,1 mm.
4 Dimensions
4.1 Conductor diameter
The series of preferred nominal conductor diameters shall correspond to series R 20 according
to ISO 3. The actual values and their tolerances are given in Tables 1 and 2.
The series of intermediate diameters from which the user may select intermediate nominal
conductor diameters, when required for technical reasons, shall correspond to series R 40
according to ISO 3. The actual values and their tolerances are given in Annex A.
The conductor diameter shall not differ from the nominal diameter by more than the limit given
in Tables 1 or 2.
NOTE For wires up to and including 0,063 mm nominal conductor diameter, see Table 3.
