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 is available as IEC 60455-3-8:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60455-3-8:2021 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. 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: - Clause 1: a link to assemblies according to IEC 60502-4 and EN 50393 was introduced; - designation: the categories, especially the mechanical ones, were redefined; - type tests: the testing was updated based on the chemical basis of the material; - type tests: additional materials were introduced; - Annex A: an examination grid was established.

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.

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 Nation
