SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES –

Part 0-2: General requirements – Enamelled rectangular copper wire

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 60317-0-2 has been prepared by IEC technical committee 55:
Winding wires.
This fourth edition cancels and replaces the third edition published in 2013. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) revision to Clause 2 to add new normative references for specifications for copper rods;
b) revision to 3.1 to add a new definition for the term “bonding layer”;
c) revision to 3.2.1 to the conditions specified for tests to be carried out;
d) revision to 4.5 to add requirements for minimal, nomimal and maximal overall dimensions
with a bonding layer;
e) revision to Clause 5 to reference specifications for rectangular and square copper rod;

f) revision to Clause 6 to take into account nominal proof strength;
g) revision to 8.2 to the adherence test requirement;
h) revision to Clause 18 to make reference to the relevant specification sheet
The text of this International Standard is based on the following documents:
FDIS Report on voting
55/1847/FDIS 55/1865/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.
This International standard is to be read in conjunction with IEC 60851 (all parts). The clause
numbers used in this part of IEC 60317 are identical with the respective test numbers of
IEC 60851 (all parts).
In case of inconsistencies between IEC 60851 and this part of IEC 60317, the latter prevails.
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 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 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 General notes
3.2.1 Methods of test
All methods of test to be used for this document are given in IEC 60851 (all parts).
The clause numbers used in this document are identical to the corresponding test numbers in
IEC 60851 (all parts).
In case of inconsistencies between the publication on methods of test and this document,
IEC 60317-0-2 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
When reference is made to a winding wire according to a standard of the IEC 60317 series
mentioned under Clause 2, the following information is given in the description:
– reference to IEC specification;
– nominal conductor dimensions in millimetres (width × thickness);
– grade;
– nominal proof strength minimum (and maximum) value.

EXAMPLE: IEC 60317-17 – 4,00 × 1,00 Grade 1 Rp = 120 N⋅mm
0.2
3.3 Appearance
The film coating shall be essentially smooth and continuous, free from streaks, blisters and
foreign material when examined with normal vision, in accordance with good commercial
practice, as wound on the original spool or reel.
4 Dimensions
4.1 Conductor dimensions
The dimensions for width and thickness of conductors of winding wires with rectangular cross-
section, recommended in this document, are taken from the R 20 series in ISO 3.
Preferred sizes are combinations of width and thickness, both in accordance with the R 20
series.
Intermediate sizes are combinations of width or thickness in accordance with the R 20 series
with the other dimension in accordance with the R 40 series.
This document covers:
– widths from 2,00 mm up to and including 31,50 mm;

The ratio width/thickness shall be within the specified limits. Combinations of R 40 and R 40
are not allowed in the case of additional sizes.
The ratio width/thickness shall be greater than or equal to 1,4:1 and shall not exceed 8:1.
The actual values of dimensions are given in Table 2.
The nominal cross-sectional areas for preferred sizes are given in Table 2, and the nominal
cross-sectional areas for intermediate sizes are given in Table A.1.
4.2 Tolerance on conductor dimensions
The conductor dimensions shall not differ from the nominal values by more than the tolerance
given in Table 1.
