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 fourth edition cancels and replaces the third edition published in 2015. 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.

c) addition of requirement for the adherence test in 8.2.1 and 8.2.2.

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

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 the 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.

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

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 in accordance with 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.
EXAMPLE IEC 60317-31 – 4,00 × 1,00 Grade 2GL1
3.3 Appearance

The fibrous covering shall be essentially smooth as agreed upon between the customer and the

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.

The fibres shall be wound evenly, bound to the copper or coating and not loose.

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 document, shall be in accordance with Table 1, and are

taken from the R 20 series in ISO 3.

Preferred and intermediate 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 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, the R 40 series shall be used when, for technical reasons, additional

sizes may be needed. 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.
