Part 1: General
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 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.
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
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. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 851-1 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:
FDIS Report on voting
55/470A/FDIS 55/511/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.

851-1 © IEC:1996 − 5 −
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);
c) packaging (IEC 264).

Part 1: General
1  Scope
This part of IEC 851 specifies the general notes on methods of test for winding wires. It
also gives the definitions for terms used in IEC 851. A survey of the contents of part 2 to
part 6 of IEC 851 is given in annex A.
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 parties to
agreements based on this part 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.
