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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

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.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

3.2 General notes on methods of test
3.2.1 Methods of test
All methods of test to be used for this document are given in the various parts to IEC 60851
(all parts).
The clause numbers used in this document are identical to the respective test numbers in
those parts of IEC 60851 (all parts).

In case of inconsistencies between the IEC 60851 parts concerning methods of test and this
document, IEC 60317-0-6 shall prevail.
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 35 40 °C and a relative humidity between 45 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.
3.2.2 Winding wire
When reference is made to a winding wire according to a standard of the IEC 60317 series
mentioned under Clause 2, the following information is given in the description:
• reference to IEC specification;
• nominal conductor diameter in millimetres;
• grade of coating and glass covering.
EXAMPLE IEC 60317-48 – 1,000 Grade 1 GL1

The type of packaging may can influence certain properties of the wire, for example
springback. Therefore, the type of packaging, for example the kind of spool, shall be agreed
between purchaser and supplier.
The wire shall be evenly and compactly wound on spools or placed in containers. No spool or
container shall contain more than one length of wire unless agreed to between purchaser and
supplier. The marking of the label when there is more than one length and/or identification of
the separate lengths in the package shall be agreed to between purchaser and supplier.
Where wires are delivered in coils, the dimensions and the maximum mass of such coils shall
be agreed between purchaser and supplier. Any additional protection for coils shall also be
agreed between purchaser and supplier.

Labels shall be securely attached to the flange of each spool and (where applicable) container
and shall include the following information:
a) manufacturer's name and/or trademark;
b) type of wire and insulation;
c) net mass of wire;
d) diameter(s) of wire and grade of insulation;
