SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES –

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.

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

the IEC 60851 series of standards.

In the case of inconsistencies between the publication on methods of test and this document,

IEC 60317-0-4 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.
---------------------- Page: 10 ----------------------
IEC 60317-0-4:2020 © IEC 2020 – 9 –

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.

The conductor dimensions shall not differ from the nominal values by more than the tolerance

given in Table 2.

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 %.

If agreed between purchaser and supplier, the corner radii for wires with a width

greater than 4,8 mm may be:
0,5 mm × t, where t is the nominal thickness of the conductor;
0,8 mm.
4.4 Increase in dimensions due to the insulation

The increase in width or thickness due to the insulation shall be as specified in Table 4.
