FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the
form of standards, technical reports or guides and they are accepted by the National Committees in that
sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the
subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60317-43 has been prepared by IEC technical committee 55:
Winding wires.
The text of this standard is based on the following documents:
FDIS Report on voting
55/540/FDIS 55/570/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.
Annexes A and B are for information only.

INTRODUCTION
This part of IEC 317 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 851);
2) specifications (IEC 317);
3) packaging (IEC 264).

SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES –
Part 43: Aromatic polyimide tape wrapped round copper wire,
class 240
1 Scope
This part of IEC 317 specifies requirements of tape wrapped round 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 at least 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 diameters covered by this standard is:
1,600 mm up to and including 5,000 mm.
The nominal conductor diameters are given in table 1.
When reference is made to winding wire according to this standard, the following information
should be given:
– reference to IEC 60317-43;
– diameter of the conductor;
– grade.
Example: 60317-43 IEC 2,000 mm grade A2
