FOREWORD
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
1)
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation 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.
The documents produced have the form of recommendations for international use and are published in the
3)
form of standards, technical reports or guides and they are accepted by the National Committees in that
sense.
In order to promote international unification, IEC National Committees undertake to apply IEC International
4)
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.
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
5)
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. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 851-6 has been prepared by IEC technical committee 55:
Winding wires.
This second edition cancels and replaces the first edition published in 1985 and
constitutes a technical revision.
The text of this standard is based on the following documents:
Report on voting
FOIS
55/475A/FD IS 55/516/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.
Annex A is for information only.

INTRODUCTION
This part of IEC 851 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:
a) methods of test (IEC 851);
b) specifications (IEC 317);
packaging (IEC 264).

WINDING WIRES - TEST METHODS -
Part 6: Thermal properties
1 Scope
This part of IEC 851 specifies the following tests:
- Test 9: Heat shock;
- Test 10: Cut-through;
- Test 15: Temperature index;
- Test 12: Loss of mass.
For definitions, general notes on methods of test and the complete series of methods of
test for winding wires see IEC 851-1.
2 Normative references
The following normative documents contain provisions which, through reference in this
text, constitute provisions of this part of IEC 851. At the time of publication, the editions
indicated were valid. All normative documents are subject to revision, and pa rties to
agreements based on this pa rt of IEC 851 are encouraged to investigate the possibility of
applying the most recent editions of the normative documents indicated below. Members
of the IEC and ISO maintain registers of currently valid International Standards.
IEC 172: 1987, Test procedure for the determination of the temperature index of
enamelled winding wires
IEC 851-1: 1996, Winding wires - Test methods - Part 1: General
IEC 851-3: 1996, Winding wires - Test methods - Part 3: Mechanical properties
IEC 851-5: 1996, Winding wires - Test methods - Part 5: Electrical properties
3 Test 9: Heat shock (applicable to enamelled and tape wrapped wire)
Heat shock is the potential of the wire to withstand temperature exposure after the wire
has been stretched and/or wound or bent around a mandrel.
3.1 Specimen
3.1.1 Round wire
A specimen shall be prepared in accordance with:
- 5.1.1 of IEC 851-3 for enamelled wires with a nominal conductor diameter up to and
including 1,600 mm;

- 5.2 of IEC 851-3 for enamelled wires with a nominal conductor diameter over
1,600 mm;
- 5.1.1 of IEC 851-3 for tape wrapped wires with a nominal conductor diameter up to
and including 1,600 mm;
5.5.4 of IEC 851-3 for tape wrapped wires with a nominal conductor diameter over
-
1,600 mm.
3.1.2 Rectangular wire
A specimen shall be prepared in accordance with 5.1.2 of IEC 851-3, bent however, only
flatwise (on the thickness).
3.2 Procedure
The specimen is placed into an oven with forced air circulation for a period of 30 min and
±5
at a temperature °C specified in the relevant standard. After removal from the oven, the
specimen shall be allowed to cool to room temperature and shall then be examined for
cracks under a magnification according to table 1.
Table 1 - Magnification
Wire dimension Magnification
Round wire of nominal conductor diameter 10 to 15 times
up to and including 0,040 mm
Round wire of nominal conductor diameter 6 to 10 times
over 0,040 mm up to and including 0,500 mm
0 to 6 times
Round wire of nominal conductor diameter over 0,500 mm
Rectangular wire 6 to 10 times
