Plastic films for electrical purposes - Part 3: Specifications for individual materials - Sheet 3: Polycarbonate (PC) films used for electrical insulation
IEC 60674-3-3: 2023 gives the requirements for polycarbonate films used for electrical insulation. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application can 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. This second edition cancels and replaces the first edition published in 1992. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the title of the standard has been changed to unify the name within the IEC 60674 series; b) update of the normative references.

IEC 60674-3-3: 2023 spécifie les exigences pour les films de polycarbonate utilisés dans l'isolation électrique. Les matériaux conformes à la présente spécification satisfont à des niveaux établis de performance. Toutefois, l'utilisateur peut choisir le matériau destiné à une application spécifique en se fondant sur les exigences réelles nécessaires pour assurer des performances adéquates dans le cadre de l'application considérée et non sur la présente spécification seule. 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 1992. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) le titre de la norme a été modifié pour harmoniser l'intitulé de la série IEC 60674; b) les références normatives ont été mises à jour.

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 certificati
