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 60317-0-7 has been prepared by IEC technical committee 55:
Winding wires.
The text of this standard is based on the following documents:
FDIS Report on Voting

This International 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 the
IEC 60851 series.
In case of inconsistencies between IEC 60851 and this part of IEC 60317, the latter shall
prevail.
The numbering of clauses in this standard is not continuous from Clauses 21 and 30 in order
to reserve space for possible future wire requirements prior to those for wire packaging.
A list of all the parts in the IEC 60317 series, published 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 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,
• withdrawn,

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 series);
2) Specifications for particular types of winding wires (IEC 60317 series);
3) Packaging of winding wires (IEC 60264 series).

3.2 General notes
3.2.1 Methods of test
All test methods used in this standard shall be applied in accordance with the test methods of
the IEC 60851 series.
The clause numbers used in this standard are identical to the corresponding test numbers in
the IEC 60851 series.
In case of inconsistencies between the test methods standard and this standard, this standard
shall prevail.
Where no specific range of nominal diameter is given for a test, the test method shall apply to
all nominal dimensions covered by this standard.
Unless otherwise agreed, all tests shall be carried out at a temperature between 15 °C and
40 °C, and at a relative humidity of 45 % to 75 %. Before each test, the specimen shall be
preconditioned under these atmospheric conditions for a time sufficient to allow the
specimens to reach a stable state. These requirements do not affect the online high voltage
continuity test according to IEC 60851-5.
The wire to be tested shall be removed from the packaging in such a way that it is not
subjected to elongation or unnecessary bending. Before each test, sufficient wire shall be
discarded to ensure that no damaged wire is included in the test specimen.
3.2.2 Winding wire
Where a wire type is referenced to Clause 2, the following information shall be provided:
– Reference to the relevant standard;
– Nominal conductor diameter in mm;
– Grade of FIW;
– Example: IEC 60317-56 – 0,500 grade of FIW 5.
3.3 Appearance
The wire coating shall be essentially smooth and uniform, and free from streaks, blisters and
foreign material in accordance with good commercial practice when examined with normal
vision, as wound on the original spool or reel.
When agreed upon between the user and supplier, examination using 6× – 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 Table 1.
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 Table A.1 of Annex A.
The conductor diameter shall not differ from the nominal diameter by more than the tolerance
given in Table 1.

column 2 of Table 1 at any point.
4.3 Minimum overall diameter
The minimum overall diameter of enamelled wires without a bonding layer shall not be less

5 Electrical resistance
For nominal conductor diameters up to and including 0,063 mm, the resistance at 20 °C shall
be within the limits in Table 2.
No resistance values are specified for nominal conductor diameters over 0,063 mm.
By agreement between purchaser and supplier, resistance measurements may be made for
nominal conductor diameters over 0,063 mm up to and including 1,000 mm. In case of such
agreement, the resistance at 20 °C shall be within the limits given in IEC 60317-0-1:2008,
Annex C.
