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 consolidated version of IEC 60317-44 consists of the first edition (1997) [documents
55/541/FDIS and 55/571/RVD] and its amendment 1 (2010) [documents 55/1182/FDIS and
55/1193/RVD]. It bears the edition number 1.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.

The committee has decided that the contents of the base publication and its amendments 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.

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 publication using a colour printer.

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. The series has three groups describing:
1) methods of test (IEC 60851);
2) specifications (IEC 60317);
3) packaging (IEC 60264).

SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES –

Part 44: Aromatic polyimide tape wrapped
rectangular copper wire, class 240



1 Scope
This part of IEC 60317 specifies the requirements of tape wrapped rectangular copper winding
wire of class 240. The insulation consists of one or two wrappings of aromatic polyimide tape.
Class 240 is a thermal class that requires a temperature index of 240 and a heat shock
temperature of at least 260 °C.
NOTE In some countries, e.g. Canada, Russia, USA, this product is assigned a class 220.
The tape is coated on one or both sides with a suitable adhesive, for instance, fluorinated
ethylene propylene. After wrapping, the tape is heat-sealed to form a continuous and adherent
sheath.
Specific requirements may be subject to contract.
The temperature in degrees Celsius corresponding to the temperature index is not necessarily
that at which the wire is recommended to be used and this will depend on many factors,
including the types 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.
The specified combinations of width and thickness as well as the specified ratio
width/thickness are given in IEC 60317-0-2.
When a reference is made to winding wire according to this standard, the following information
should be given:
– reference to IEC 60317-44;
– dimension of the nominal conductor (width x thickness);
– grade.
Example: 60317-44 IEC 4,00 mm x 1,00 mm grade A2
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 of
the referenced document (including any amendments) applies.

– 8 – 60317-44 © IEC:1997+A1:2010
Where no specific range of nominal conductor dimensions is given for a test, the test applies to
all nominal conductor dimensions covered by the specification sheet.
Unless otherwise specified, all tests shall be carried out at a temperature from 15 °C to 35 °C
and a relative humidity from 45 % to 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.
4 Dimensions
The dimensions due to the insulation depend upon an agreement between purchaser and
supplier. The dimensions in this standard shall be used as a guide in forming that agreement.
4.1 Conductor dimensions
See 4.1 of IEC 60317-0-2.
4.2 Tolerance on conductor dimensions
