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 60317-4 has been prepared by IEC technical committee 55:

Winding wires.

This fourth edition cancels and replaces the third edition published in 1990, Amendment

1:1997 and Amendment 2:1999. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

– new 3.2.2 containing general notes on winding wire, formerly a part of the scope;

– new 3.2.3 containing requirements for appearance;

– revision to references to IEC 60317-0-1:2013 to clarify that their application is normative;

– consolidation of 17.1 and 17.2 of the solderability requirements;
– revision to Clause 19, dielectric dissipation factor;
– new Clause 23, pin hole test.

CDV Report on voting
55/1459/CDV 55/1498/RVC

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.

This International Standard is to be read in conjunction with IEC 60317-0-1:2013.

The numbering of clauses in this standard is not continuous from Clauses 20 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 publication will remain unchanged until

the stability date indicated on the IEC web site 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 series);
2) Specifications for particular types of winding wires (IEC 60317 series);
3) Packaging of winding wires (IEC 60264 series).

SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES –
Part 4: Solderable polyurethane enamelled round copper wire, class 130
1 Scope

This part of IEC 60317 specifies the requirements of solderable enamelled round copper

winding wire of class 130 with a sole coating based on polyurethane resin, which may be

modified provided it retains the chemical identity of the original resin and meets all specified

wire requirements.

NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives to

enhance certain performance or application characteristics.
The range of nominal conductor diameters covered by this standard is:
– Grade 1: 0,018 mm up to and including 2,000 mm;
– Grade 2: 0,020 mm up to and including 2,000 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013.
2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and

are indispensable for its application. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any

The temperature in degrees Celsius corresponding to the temperature index is not necessarily

that at which it is recommended that the wire be operated and this will depend on many

factors, including the type of equipment involved.
