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:
Winding wires.
This second edition cancels and replaces the first edition published in 2012. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) revision to the title of the standard indicating that the glass fibre covering is fused and
unvarnished;
b) revision to subclause 3.2 adding winding wire requirements for the fibrous covering and a
list of covering classifications;

c) revision to subclause 3.3 requirements for appearance;
d) revision to subclause 8.2, adherence test requirements.
The text of this standard is based on the following documents:
FDIS Report on voting
55/1784/FDIS 55/1796/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
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 numbering of clauses in this standard is not continuous from Clauses 21 through 30 in
order to reserve space for possible future wire requirements prior to those for wire packaging.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

3.2.1 Methods of test
All methods of test to be used for this document are given in the IEC 60851 series.
The clause numbers used in this document are identical with the respective test numbers in
the IEC 60851 series.
In case of inconsistencies between the IEC 60851 series and this document, IEC 60317-0-8
shall prevail.
Where no specific range of nominal conductor dimensions is given for a test, the test applies
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 25 % 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.
3.2.2 Winding wire
The fibre covering shall consist of a combination of polyester and glass fibres. The glass
fibres shall be electrical-grade continuous-filament glass yarn. The polyester fibre shall be a
high-grade yarn resulting from the linear polymerization of ethylene glycol and terephthalic
acid. The maximum content by weight of polyester fibre in the yarn shall not exceed 50 %.
The coating shall be characterized by the following different grades of thickness:
• PG1, bare conductor with 1 layer of polyester glass fibre or 2 layers of finer polyester
glass fibres that together, comply with the dimensional requirements in Table 1;
• PG2, bare conductor with 2 layers of polyester glass fibre;
• Grade 1 PG1, enamelled grade 1 (grade 1) with 1 layer of polyester glass fibre (PG1);
• Grade 1 PG2, enamelled grade 1 (grade 1) with 2 layers of polyester glass fibre (PG2);
• Grade 2 PG1, enamelled grade 2 (grade 2) with 1 layer of polyester glass fibre (PG1);
• Grade 2 PG2, enamelled grade 2 (grade 2) with 2 layers of polyester glass fibre (PG2).
When reference is made to a winding wire according to a standard of the IEC 60317 series,
the following information is given in the description:
• reference to IEC specification;
• nominal conductor dimensions in millimetres (width × thickness);
• grade.
EXAMPLE IEC 60317-60 – 4,00 × 1,00 Grade 2PG1.
3.3 Appearance
The fibrous covering shall be essentially smooth and uniform as agreed upon between
customer and supplier in accordance with good commercial practice, and free from physical
damage and foreign material when examined with normal vision, as wound on the original
spool or reel. Fibres shall be bound to the underlying enamelled or bare wire.
NOTE Evidence of physical damage includes gashes, broken fibre strands, and the like.
4 Dimensions
4.1 Conductor dimensions
The dimensions for widths and thicknesses of conductors of winding wires with rectangular
cross-section recommended in this part of IEC 60317 shall be in accordance with Table 1,

The minimum overall dimensions shall be calculated as the sum of the minimum bare
dimension and the minimum increase in dimension due to the insulation.
4.5.3 Maximum overall dimensions
The maximum overall dimensions shall be calculated as the sum of the maximum bare
dimension and the maximum increase in dimension due to the insulation.
5 Electrical resistance
The resistance of the wire shall be expressed as the DC resistance at 20 °C. The method
used shall provide an accuracy of 0,5 %.
The maximum value of resistance shall be not greater than the value calculated for the
minimum tolerated cross-sectional area of the conductor resulting from the minimum
dimensions in thickness and width and the maximum for the corner radius, and with a
–1
resistivity of 1/58 Ω mm² m .
One measurement shall be made.

30 Packaging
The kind of packaging may influence certain properties of the wire, for example springback.
Therefore the kind of packaging, for example the type of spool, shall be agreed between
purchaser and supplier.
The wire shall be evenly and compactly wound on spools or placed in containers. In order to
reduce the risk of wire damage, the spool with the wire shall be delivered and used with the
axis in horizontal position. No spool or container shall contain more than one length of wire
unless agreed between purchaser and supplier. Marking of the label when there is more than
one length and/or identification of the separate lengths in the package shall be agreed
between purchaser and supplier.
Where wires are delivered in coils, the dimensions and the maximum weights of such coils
shall be agreed between purchaser and supplier. Any additional protection for coils shall also
be agreed between purchaser and supplier.
Labels shall be attached to each packaging unit as agreed between supplier and user and
shall include the following information:
a) manufacturer’s name and/or trade mark;
b) type of wire and insulation, for instance trade name and/or IEC specification number;
c) net mass of wire;
d) nominal dimension(s) of wire and grade of insulation;
e) date of manufacture.
