(Main)Specifications for particular types of winding wires - Part 18: Polyvinyl acetal enamelled rectangular copper wire, class 120
Specifications for particular types of winding wires - Part 18: Polyvinyl acetal enamelled rectangular copper wire, class 120
IEC 60317-18:2020 specifies the requirements of enamelled rectangular copper winding wires of class 120 with a sole coating based on polyvinyl acetal or polyvinyl formal resin, which can be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements
NOTE 1 A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics.
NOTE 2 Polyvinyl acetate is a general name for a family of thermoplastic vinyl resins produced by the condensation of polyvinyl alcohol with an aldehyde. Examples are polyvinyl acetal, polyvinyl formal and polyvinyl butyral.
The range of nominal conductor dimensions covered by this document is:
- width: min. 2,0 mm max. 31,5 mm;
- thickness: min. 0,80 mm max. 10,0 mm.
Wires of grade 1 and grade 2 are included in this specification and apply to the complete range of conductors. The specified combinations of width and thickness as well as the specified ratio width/thickness are given in IEC 60317-0-2. This fourth edition cancels and replaces the third edition published in 2004 and Amendment 1:2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- modification of the Scope (Clause 1);
- revision to thermal class designation from 105 to 120 in 3.2.2;
- renaming of stretching test to adherence test, and modification to the requirements in 8.2;
- revision to the cut-through requirement in Clause 10.
Spécifications pour types particuliers de fils de bobinage - Partie 18: Fil de section rectangulaire en cuivre émaillé avec acétal de polyvinyle, classe 120
IEC 60317-18: 2020 spécifie les exigences relatives aux fils de bobinage de section rectangulaire en cuivre émaillés de classe 120 avec un revêtement simple à base de résine acétal de polyvinyle ou formal de polyvinyle qui peut être modifiée sous réserve qu'elle conserve l'identité chimique de la résine initiale et respecte l'ensemble des exigences spécifiées du fil.
NOTE 1 Une résine modifiée est une résine dont les propriétés chimiques ont été modifiées ou qui contient un ou plusieurs additifs visant à améliorer certaines performances ou caractéristiques d'application.
NOTE 2 L'acétate de polyvinyle est le nom générique désignant une famille de résines thermoplastiques vinyliques produites par la condensation de l'alcool polyvinylique avec un aldéhyde. Des exemples sont l'acétal de polyvinyle, le formal de polyvinyle et le butyral de polyvinyle.
La gamme des dimensions nominales des conducteurs couvertes par le présent document est:
largeur: min. 2,0 mm max. 31,5 mm;
épaisseur: min. 0,80 mm max. 10,0 mm.
Les fils de grades 1 et 2 sont couverts par la présente spécification et s'appliquent à toute la gamme de conducteurs. Les combinaisons largeur-épaisseur spécifiées ainsi que le rapport largeur/épaisseur spécifié sont indiqués dans l'IEC 60317-0-2. Cette quatrième édition annule et remplace la troisième édition parue en 2004, et l'Amendement 1: 2009. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
modification du domaine d’application (Article 1);
révision de la désignation de classe thermique de 105 à 120 en 3.2.2;
"essai d’étirement" renommé "essai d’adhérence", et modification des exigences en 8.2;
révision de l’exigence relative à la thermoplasticité à l’Article 10.

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.
