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;
---------------------- Page: 10 ----------------------

IEC 60317-0-8:2019 © IEC 2019 – 5 –
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.

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,

and are taken from the R 20 series according to ISO 3.

Preferred sizes are combinations of width and thickness both according to the R 20 and R 40

series.
