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 60317-0-7 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) reduction in the number of grades of FIW from 3 through 9 to 4, 6 and 8 only;

b) reduction of the wire diameter range from (0,040 to 1,000) mm to (0,090 to 0,900) mm for

several requirements;
c) revision of Clause 5 to delete the Table 2 resistance requirements;
---------------------- Page: 10 ----------------------

IEC 60317-0-7:2017 © IEC 2017 – 5 –

d) revision of Clause 13 to clarify that breakdown is determined when a calculated minimum

test voltage is reached, which can be less than 10 000 V;

e) expansion of Annex A to include requirements for FIW 3, 5, 7 and 9 and for all grades,

wire diameters below 0,090 mm and above 0,900 mm.
The text of this International Standard is based on the following documents:
FDIS Report on voting
55/1619/FDIS 55/1623/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 parts in the IEC 60317 series, published under the general title Specifications for

particular type 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

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,

all nominal dimensions covered by this document.

Unless otherwise agreed, all tests shall be carried out at a temperature between 15 °C and

40 °C, and at a relative humidity of 45 % to 75 %. Before each test, the specimen shall be

preconditioned under these atmospheric conditions for a time sufficient to allow the

specimens to reach a stable state. These requirements do not affect the online high voltage

continuity test according to IEC 60851-5.

The wire to be tested shall be removed from the packaging in such a way that it is not

subjected to elongation or unnecessary bending. Before each test, sufficient wire shall be

discarded to ensure that no damaged wire is included in the test specimen.
