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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

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 60317-0-6 has been prepared by IEC technical committee 55:

Winding wires.
This second edition cancels and replaces the first edition published in 2001 and
Amendment 1:2006. This edition constitutes a technical revision.

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

edition:
– revision to 3.3, Appearance;

– revision to Table 1, maximum overall diameter of grade 1 wire over single-glass fibre

covering for nominal conductor diameters 1,600 mm – 5,000 mm;

– revision to Table 2, maximum overall diameter of grade 1 wire over double-glass fibre

covering for nominal conductor diameters 1,600 mm – 5,000 mm;
– clarification in Table 3 measurement of elongation as “minimum elongation %”.

The text of this International Standard is based on the following documents:
FDIS Report on voting
55/1851/FDIS 55/1866/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.

This International standard is to be read in conjunction with IEC 60851 (all parts). The clause

numbers used in this part of IEC 60317 are identical with the respective test numbers of

IEC 60851 (all parts).

In case of inconsistencies between IEC 60851 (all parts) and this part of IEC 60317, the latter

prevails.

The numbering of clauses in this standard is not continuous from Clauses 21 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 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.

Where no specific range of nominal conductor diameters is given for a test, the test applies to

all nominal conductor diameters covered by the specification sheet.

Unless otherwise specified, all tests shall be carried out at a temperature ranging between

15 °C and 40 °C and a relative humidity between 25 % and 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.

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.

For intermediate nominal conductor diameters, the minimum increase figure corresponding to the next larger

nominal conductor diameter shall be taken.

NOTE 1 The dimensions of the intermediate nominal conductor diameters for the R40 series are given in

Annex A.

NOTE 2 Grade G2 is a double glass-fibre covering over bare wire. Grade 1G2 is a double glass-fibre covering

over grade 1 enamelled wire. Grade 2G2 is a double glass-fibre covering over grade 2 enamelled wire.

4.2 Out of roundness of the conductor

The difference between the minimum and maximum diameter, at any one point, shall not be

more than the figure given in column 2 of Table 1 or Table 2.
4.3 Minimum increase in diameter due to the covering

The minimum increase in diameter due to the covering shall not be less than the values given

in Table 1 or Table 2.
4.4 Maximum overall diameter

The maximum overall diameter shall not exceed the values given in Table 1 or Table 2.

5 Electrical resistance
No minimum and maximum resistance values are specified.
For nominal resistance values see Annex B.
6 Elongation
The minimum elongation shall not be less than the values given in Table 3. These
requirements shall apply to nominal conductor diameters over 0,630 mm.

7 Springiness
7.1 Nominal conductor diameters up to and including 1,600 mm
No requirements specified.
7.2 Nominal conductor diameters over 1,600 mm
The wire shall not exceed the maximum springback of:
– 5° for wires with a glass-fibre covering over a bare conductor;
– 5,5° for wires with a glass-fibre covering over an enamelled conductor.
8 Flexibility and adherence

The covering shall not open sufficiently to expose the bare or enamelled wire after bending on

a mandrel diameter of ten times the nominal conductor diameter.
9 Heat shock
Test inappropriate.
10 Cut-through
Test inappropriate.
11 Resistance to abrasion
Test inappropriate.
