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.
This International Standard has been prepared by IEC technical committee 55: Winding wires.
This third edition of IEC 60317-17 cancels and replaces the second edition issued in 1990, its
Amendment 1 (1997) and its Amendment 2 (2005). This edition constitutes a technical
revision.
The main change with respect to the previous edition is listed below:
– Clause 20: reference to the transformer oil resistance test method in IEC 60851-4.

– 4 – 60317-17 © IEC:2010
The text of this standard is based on the following documents:
FDIS Report on voting
55/1180/FDIS 55/1191/RVD
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 60317-0-2 (1997).
A list of all the parts in the IEC 60317 series, 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 amendment and the base 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 and test methods (IEC 60851);
2) specifications for particular types of winding wire (IEC 60317);
3) packaging of winding wires (IEC 60264).

SPECIFICATIONS FOR PARTICULAR
TYPES OF WINDING WIRES –
Part 17: Polyvinyl acetal enamelled rectangular
copper wire, class 105
1 Scope
This part of IEC 60317 specifies the requirements of enamelled rectangular copper winding
wire of class 105 with a sole coating based on polyvinyl acetal resin, which may be modified
providing 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.
Class 105 is a thermal class that requires a minimum temperature index of 105 and a heat
shock temperature of at least 155 °C.
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.
The range of nominal conductor dimensions covered by this standard is
– width: min.  2,00 mm max. 16,00 mm;
– thickness: min.  0,80 mm max.  5,60 mm.
Wires of grade 1 and grade 2 are included in this specification and apply to the complete
range of conductors.
The specified combinations of width and thickness as well as the specified ratio
width/thickness are given in IEC 60317-0-2.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
