IEC 60317-72:2020

Specifications for particular types of winding wires - Part 72: Polyester glass-fibre wound silicone resin/varnish impregnated, bare or enamelled round copper wire, temperature index 200

IEC 60317-72: 2020 specifies the requirements of polyester glass-fibre wound silicone resin/varnish impregnated, bare, grade 1 or grade 2 enamelled round copper winding wire, temperature index 200. NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot be specified. The nominal conductor diameters are specified in IEC 60317-0-10:2017, Clause 4. This second edition cancels and replaces the first edition published in 2017. The document 55/1768/CDV, circulated to the National Committees as Amendment 1, led to the publication of this new edition. This edition includes the following significant technical changes with respect to the previous edition:
- modification of the title;
- revision to the Scope;
- revision to 3.2.2.

Spécifications pour types particuliers de fils de bobinage - Partie 72: Fil de section circulaire en cuivre nu ou émaillé, guipé de fibres de verre polyester imprégnées de vernis ou de résine silicone, d'indice de température 200

IEC 60317-72:2020 spécifie les exigences relatives au fil de bobinage de section circulaire en cuivre nu ou émaillé de grade 1 ou de grade 2, guipé de fibres de verre polyester imprégnées de vernis ou de résine silicone, d’indice de température 200. NOTE Pour ce type de fil, l'essai de choc thermique n'est pas approprié et c'est la raison pour laquelle il n'est pas possible d'établir une température de choc thermique. Par conséquent, il n’est pas possible de spécifier une classe fondée sur les exigences d'indice de température et de température de choc thermique. Les diamètres nominaux du conducteur sont spécifiés à l’Article 4 de l’IEC 60317-0-10:2017. Cette deuxième édition de l'IEC 60317-72 annule et remplace la première édition parue en 2017. Le document 55/1768/CDV, circulé comme Amendement 1 auprès des Comités nationaux de l'IEC, a conduit à la publication de cette nouvelle édition. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- modification du titre;
- révision du Domaine d'application;
- révision du 3.2.2.

SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES –

Part 72: Polyester glass-fibre wound fused, silicone resin or /varnish
impregnated, bare or enamelled round copper wire, temperature index 200

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 redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

International Standard IEC 60317-72 has been prepared by IEC technical committee 55:
Winding wires.
This second edition cancels and replaces the first edition published in 2017. The document
55/1768/CDV, circulated to the National Committees as Amendment 1, led to the publication
of this new edition.
This edition includes the following significant technical changes with respect to the previous
edition:
– modification of the title;
– revision to the Scope;
– revision to 3.2.2.
The text of this standard is based on the first edition, its Amendment 1 and the following
documents:
CDV Report on voting
55/1768/CDV 55/1817/RVC
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.
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.
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 document 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) 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 72: Polyester glass-fibre wound fused, silicone resin or /varnish

1 Scope
This part of IEC 60317 specifies the requirements of polyester glass-fibre wound fused,
silicone resin or /varnish impregnated, bare, grade 1 or grade 2 enamelled round copper
winding wire, temperature index 200. The impregnating agent is a silicone containing resin or
varnish.
NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be
established. Consequently, a class based on the requirements for temperature index and heat shock temperature
cannot be specified.
The nominal conductor diameters are specified in IEC 60317-0-10:2017, Clause 4.
