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 60317-80 has been prepared by IEC technical committee 55:
Winding wires.
The text of this International Standard is based on the following documents:
FDIS Report on voting
55/1790/FDIS 55/1802/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 60317-0-2:2019.

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 numbering of clauses in this standard is not continuous from Clauses 21 through 30 in
order to reserve space for possible future wire requirements prior to those for wire packaging.
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.
INTRODUCTION
This part of IEC 60317 forms an element of a series of standards which deals with insulated
wires used for windings in electrical equipment. It is composed of the following series:
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 80: Polyvinyl acetal enamelled rectangular copper wire,
class 120, with a bonding layer

1 Scope
This part of IEC 60317 specifies the requirements of enamelled rectangular copper winding wire
of class 120 with a dual coating. The underlying coating is based on polyvinyl acetal resin,
which can be modified providing it retains the chemical identity of the original resin and meets
all specified wire requirements. The second coating is a bonding layer based on a thermoplastic
or thermosetting resin.
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 dimensions covered by this document 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 nominal width and thickness as well as the specified ratio
width/thickness are given in IEC 60317-0-2:2019.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies.
For undated references, the latest edition of the referenced document (including any
amendments) applies.

3.2 General notes
3.2.1 Methods of test
Subclause 3.2.1 of IEC 60317-0-2:2019 applies. In case of inconsistencies between IEC 60317-
0-2:2019 and this part of IEC 60317, this document IEC 60317-80 shall prevail.
3.2.2 Winding wire
Class 120 is a thermal class that requires a minimum temperature index of 120 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.
3.3 Appearance
Subclause 3.3 of IEC 60317-0-2:2019 applies.
4 Dimensions
4.1 Conductor dimensions
Subclause 4.1 of IEC 60317-0-2:2019 applies.
4.2 Enamel layer
Subclause 4.2 of IEC 60317-0-2:2019 applies.
4.3 Bonding layer
Clause 4.4.2 of IEC 60317-0-2:2019 applies.
5 Electrical resistance
Clause 5 of IEC 60317-0-2:2019 applies.
6 Elongation
Clause 6 of IEC 60317-0-2:2019 applies.
NOTE When the value of the proof strength of the copper is specified between minimum and maximum limits, the
requirements are agreed upon between the purchaser and supplier. The description of the term “proof strength” and
the method of determination are given in ISO 6892-1:2016.
7 Springiness
Clause 7 of IEC 60317-0-2:2019 applies.
