Plastic films for electrical purposes - Part 3: Specifications for individual materials - Sheets 4: Polyimide films used for electrical insulation
This International Standard gives the requirements for polyimide films used for electrical purposes. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. Safety warning: it is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner.

IEC 60674-3-4:2022 spécifie les exigences pour les films de polyimide à usages électriques. Les matériaux conformes à la présente spécification satisfont à des niveaux établis de performance. Toutefois, le choix d’un matériau par un utilisateur pour une application spécifique repose sur les exigences réelles nécessaires pour obtenir des performances adéquates de l’application concernée, et non sur la seule présente spécification. Avertissement de sécurité: il incombe à l'utilisateur des méthodes contenues ou référencées dans le présent document de s'assurer que celles-ci sont utilisées en toute sécurité. Cette deuxième édition annule et remplace la première édition parue en 1993. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: le présent document a fait l'objet d'une révision rédactionnelle et technique complète, et a été intégré à la série de normes IEC 60674; de nouveaux types ont été ajoutés; les plages d'épaisseurs ont été étendues; des modifications ont été apportées aux exigences relatives à certains types existants.

49 FOREWORD
50 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
51 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
52 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
53 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
54 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
55 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
56 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
57 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
58 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
59 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
60 consensus of opinion on the relevant subjects since each technical committee has representation from all
61 interested IEC National Committees.62 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
63 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
64 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
65 misinterpretation by any end user.66 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
67 transparently to the maximum extent possible in their national and regional publications. Any divergence between
68 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
69 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
70 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
71 services carried out by independent certification bodies.72 6) All users should ensure that they have the latest edition of this publication.
73 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
74 members of its technical committees and IEC National Committees for any personal injury, property damage or
75 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
76 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
77 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
78 indispensable for the correct application of this publication.79 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
80 rights. IEC shall not be held responsible for identifying any or all such patent rights.
81 International Standard IEC 60674-3-4 has been prepared by IEC technical committee 15: Solid
82 electrical insulating materials.83 This Second edition cancels and replaces the first edition published in 1993. This edition
84 constitutes a technical revision.85 This edition includes the following significant technical changes with respect to the previous
86 edition:87 a) this document has been completely revised editorially and technically and included in the
88 IEC 60674 series of standards;89 b) new types have been included;
90 c) the ranges of thickness have been expanded;
91 d) changes have been made to the requirements of some existing types;
