IEC 60317-55:2013

Specifications for particular types of winding wires - Part 55: Solderable polyurethane enamelled round copper wire overcoated with polyamide, class 180

IEC 60317-55:2013 specifies the requirements of solderable enamelled round copper winding wire of class 180 with a dual coating. The underlying coating is based on polyurethane resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is based on polyamide resin. NOTE - 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. The range of nominal conductor diameters covered by this standard is as follows:
- Grade 1: 0,020 mm up to and including 1,600 mm;
- Grade 2: 0,020 mm up to and including 1,600 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- revision to Clause 23, Pin hole test. Keywords: requirements of solderable enamelled round copper winding wire, class 180, dual coating
This publication is to be read in conjunction with IEC 60317-0-1:2013.

Spécifications pour types particuliers de fils de bobinage - Partie 55: Fil brasable de section circulaire en cuivre émaillé avec polyuréthane et avec surcouche polyamide, classe 180

La CEI 60317-55:2013 spécifie les exigences relatives au fil de bobinage brasable de section circulaire en cuivre émaillé de classe 180 avec un double revêtement. La sous-couche est à base de résine polyuréthane, qui peut être modifiée sous réserve de conserver l'identité chimique de la résine initiale et de répondre à toutes les exigences spécifiées pour le fil. La surcouche est à base de résine polyamide. NOTE - Une résine modifiée est une résine qui a subi une modification chimique, ou qui contient un ou plusieurs additifs pour améliorer certaines performances ou les caractéristiques d'utilisation. La gamme des diamètres nominaux des conducteurs couverte par la présente norme est la suivante:
- Grade 1: 0,020 mm jusques et y compris 1,600 mm;
- Grade 2: 0,020 mm jusques et y compris 1,600 mm. Les diamètres nominaux des conducteurs sont spécifiés à l'Article 4 de la CEI 60317-0-1:2013. Cette deuxième édition annule et remplace la première édition parue en 2007. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- révision de l'Article 23, Détection des microfissures en immersion. Mots clés: exigences relatives au fil de bobinage brasable de section circulaire en cuivre émaillé, classe 180, double revêtement
Cette publication doit être lue conjointement avec la CEI 60317-0-1:2013.

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.
International Standard IEC 60317-55 has been prepared by IEC technical committee 55:
Winding wires.
This second edition cancels and replaces the first edition published in 2007. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– revision to Clause 23, Pin hole test.
