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 60317-0-4 has been prepared by IEC technical committee 55:
Winding wires.
This third edition cancels and replaces the second edition published in 1997,
Amendment 1:1999 and Amendment 2:2005. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) addition of dimensional requirements for grade 1 enamelled wire in Table 4;
b) addition of dielectric breakdown requirements for grade 1 enamelled wire in Table 7.

The text of this standard is based on the following documents:
FDIS Report on voting
55/1550/FDIS 55/1565/RVD
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 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.
This standard is to be read in conjunction with the IEC 60851 series. The clause numbers
used in this standard are identical with the respective test numbers of the IEC 60851 series.
In case of inconsistencies between IEC 60851 and this standard, the latter prevails.
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 publication will remain unchanged until
the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

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).

impregnated, bare or enamelled rectangular copper wire.
The range of nominal conductor dimensions is given in the relevant specification sheet.

3.2 General notes
3.2.1 Methods of test
All methods of test to be used for this part of IEC 60317 are given in the IEC 60851 series of
standards.
The clause numbers used in this part of IEC 60317 are identical with the respective test
numbers in the IEC 60851 series of standards.
In case of inconsistencies between the publication on test methods and this part of
IEC 60317, the latter 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 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 it is not
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,
the following information is given in the description:
– reference of the IEC specification;
– nominal conductor dimensions in millimetres (width × thickness);
– grade.

3.3 Appearance
The fibrous covering shall be essentially smooth and continuous, and free from physical
damage and foreign material when examined with normal vision, as wound on the original
spool or reel.
NOTE Evidence of physical damage includes gashes, broken fibre strands, and the like.
4 Dimensions
4.1 Conductor dimensions
The dimensions for widths and thickness of conductors of winding wires with rectangular
cross-section recommended in this part of IEC 60317 shall be in accordance with Table 1,
and are taken from the R 20 series according to ISO 3.
Preferred and intermediate sizes are combinations of width and thickness both according to
the R 20 series.
This part of IEC 60317 covers:
– widths from 2,00 mm up to and including 16,00 mm;
– thicknesses from 0,80 mm up to and including 5,60 mm.
For thickness 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 width/thickness shall be within the specified limits and
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 1.
The nominal cross-sectional areas for preferred sizes are given in Table 1 and the nominal
cross-sectional areas for intermediate sizes are given in Annex A.

4.3 Rounding of corners
The arc shall merge smoothly into the flat surfaces of the conductor and the strip shall be free
from sharp, rough and projecting edges. The conductor shall have corner radii complying with
Table 3. The specified radii shall be maintained within ± 25 %.

The maximum increase in thickness or width due to the insulation may be exceeded, provided the overall thickness or width of the insulated wire does not exceed the sum of
the maximum thickness or width of the bare wire plus the maximum increase in dimension.
NOTE The minimum increases in dimensions apply only to the increase in thickness.
