SIST EN IEC 60455-3-8:2021

Resin based reactive compounds used for electrical insulation - Part 3-8: Specifications for individual materials - Resins for cable accessories (IEC 60455-3-8:2021)

This part of IEC 60455 gives the requirements for resins for power cable accessories that
conform to this specification and meet established levels of performance. However, the
selection of a material by a user for a specific application will be based on the actual
requirements necessary for adequate performance in that application and not on this
specification alone.
These materials are designed to be used in low and medium voltage cable accessories and as
such, electrical performance is proven as part of the assembly. Examples of this are described
in EN 50393 and IEC 60502-4.

IEC 60455-3-8:2021 est disponible sous forme de IEC 60455-3-8:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

L'IEC 60455-3-8:2021 contient les exigences relatives aux résines pour accessoires de câble de puissance conformes à la présente spécification et satisfaisant aux niveaux de performances établis. Cependant, le choix d’un matériau, par un utilisateur, pour une application spécifique sera fondé sur les exigences réelles nécessaires pour une performance adéquate de cette application, et non fondé sur cette seule spécification. Ces matériaux sont conçus pour être utilisés avec des accessoires de câbles à basse et moyenne tension et, de fait, les performances électriques sont attestées en tant que partie intégrante de l’assemblage. Des exemples sont fournis dans l’EN 50393 et l’IEC 60502-4. Cette deuxième édition annule et remplace la première édition parue en 2013. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Article 1: un lien pour les assemblages conformément à l’IEC 60502-4 et à l’EN 50393 a été ajouté;
- désignation: les catégories, en particulier celles relatives à la mécanique, ont été redéfinies;
- essais de type: l’essai a été mis à jour en fonction de l’origine chimique du matériau;
- essais de type: des matériaux supplémentaires ont été ajoutés;
- Annexe A: une grille d’évaluation a été créée.

RESIN BASED REACTIVE COMPOUNDS USED
FOR ELECTRICAL INSULATION –

Part 3-8: Specifications for individual materials –
Resins for cable accessories

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 60455-3-8 has been prepared by IEC technical committee 15: Solid
electrical insulating materials.
This second edition cancels and replaces the first edition published in 2013. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Clause 1: a link to assemblies according to IEC 60502-4 and EN 50393 was introduced;
b) designation: the categories, especially the mechanical ones, were redefined;
c) type tests: the testing was updated based on the chemical basis of the material;
d) type tests: additional materials were introduced;
e) Annex A: an examination grid was established.

INTRODUCTION
This part of IEC 60455 is one of a series which deals with specifications for reactive compounds
and their components for electrical insulation. This series consists of three parts:
Part 1: Definitions and general requirements (IEC 60455-1);
Part 2: Methods of test (IEC 60455-2);
Part 3: Specifications for individual materials (IEC 60455-3)
IEC 60455-3-8 is one of the specification sheets comprising Part 3 as follows:
