IEC 60317-0-8:2019

Specifications for particular types of winding wires - Part 0-8: General requirements - Polyester glass-fibre wound unvarnished and fused, or resin or varnish impregnated, bare or enamelled rectangular copper wire

IEC 60317-0-8:2019 specifies the general requirements of polyester glass-fibre wound fused, unvarnished, or resin or varnish impregnated bare, or grade 1 or grade 2 or enamelled rectangular copper winding wires. The range of nominal conductor dimensions is given in 4.1 and in the relevant specification sheet. This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- revision to the title of the standard indicating that the glass fibre covering is fused and unvarnished;
- revision to subclause 3.2 adding winding wire requirements for the fibrous covering and a list of covering classifications;
- revision to subclause 3.3 requirements for appearance;
- revision to subclause 8.2, adherence test requirements.
Keywords: insulated wires used for windings in electrical equipment

Spécifications pour types particuliers de fils de bobinage - Partie 0-8: Exigences générales - Fil de section rectangulaire en cuivre nu ou émaillé, guipé de fibres de verre avec polyester fondues sans vernis, ou imprégnées de résine ou de vernis

L'IEC 60317-0-8:2019 spécifie les exigences générales pour les fils de bobinage de section rectangulaire en cuivre nus ou émaillés, soit de grade 1 soit de grade 2, guipés de fibres de verre avec polyester fondues, non vernies, ou imprégnées de résine ou de vernis. La gamme des dimensions nominales des conducteurs est donnée au 4.1 et dans la feuille de spécification correspondante. Cette deuxième édition annule et remplace la première édition parue en 2012. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- révision du titre de la norme indiquant que l'enveloppe de fibre de verre est fondue et sans vernis;
- révision du paragraphe 3.2 comprenant l'ajout d'exigences pour les fils de bobinage pour l'enveloppe fibreuse et une liste de classifications d'enveloppes;
- révision des exigences du paragraphe 3.3 relatives à l'aspect;
- révision du paragraphe 8.2, exigences portant sur l'essai d’adhérence.

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 60317-0-8 has been prepared by IEC technical committee 55:
Winding wires.
This second edition cancels and replaces the first edition published in 2012. This edition
constitutes a technical revision.
