Electric cables - Accessories - Material characterization - Part 1: Fingerprinting for resinous compounds
This document specifies the test methods and requirements of tests for fingerprinting (as defined in 3.9) of solvent-free polymerizable, reacting resinous compound intended to be used for electrical insulation and/or mechanical protection in cable accessories covered by EN 50393, HD 629.1 and HD 629.2, for low and medium voltage up to 20,8/36 (42) kV.
Fingerprinting testing of materials does not have a mandatory link to type testing of accessories. It is regarded as stand-alone tests, but it may be carried out in combination with the accessory type tests.
NOTE Information on health and safety is given in Annex A.

Câbles électriques - Accessoires - Caractérisation des matériaux - Partie 1: Essais d'identification pour les composés résineux
Le présent document spécifie les méthodes et les exigences d’essai pour les essais d’identification (tels qu’ils sont définis en 3.9) des composés résineux réactifs polymérisables sans solvant destinés à être utilisés pour l’isolation électrique et/ou la protection mécanique dans les accessoires de câbles couverts par l'EN 50393, le HD 629.1 et le HD 629.2, pour la basse et la moyenne tension jusqu’à 20,8/36 (42) kV.
Il n’existe pas de lien obligatoire entre les essais d’identification des matériaux et les essais de type des accessoires. Ils sont considérés comme des essais indépendants, mais ils peuvent être réalisés conjointement avec les essais de type des accessoires.
NOTE Des informations concernant la santé et la sécurité sont données à l'Annexe A.
