Annotation of standard text IEC 60667-2-ed.2.0 :
IEC 60667-2:2020 gives methods of test for vulcanized fibre sheets for electrical purposes. Material made by combining with an adhesive several thicknesses of vulcanized fibre is not covered by this document. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application is 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 1982. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) added Terms and definitions b) added General notes on tests c) added Thickness instead of dimension d) changed Apparent density from Density e) added Arc resistance f) deleted Sulphate content g) added method (Bending) for flexibility h) changed test method for internal ply adhesion i) added Shrinkage IEC 60667-2:2020 specifie les methodes d’essai pour les feuilles en fibres vulcanisees a usages electriques. Les materiaux composites constitues de plusieurs couches de fibre vulcanisee assemblees par un adhesif ne sont pas couverts par le present document. Les materiaux conformes a la presente specification satisfont aux niveaux de performance etablis. Cependant, le choix du materiau par un utilisateur pour une application specifique est fonde sur les exigences reellement necessaires pour une performance appropriee et non sur cette seule specification. Mise en garde: Il est de la responsabilite de l’utilisateur des methodes contenues ou mentionnees dans le present document de veiller a ce qu’elles soient utilisees en toute securite. Cette deuxieme edition annule et remplace la premiere edition parue en 1982. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) ajout de l’Article "Termes et definitions" b) ajouts dans l’Article "Remarques generales sur les essais" c) ajout du terme "epaisseur" en remplacement du terme "dimension" d) remplacement du terme "masse volumique" par "masse volumique apparente" e) ajout du contenu a l’Article "Resistance a l’arc" f) suppression de l’Article "Teneur en sulfate" g) ajout d’une methode d’essai (Courbure) pour la flexibilite h) modification de la methode d’essai pour l’adherence interne du feuilletage i) ajout de l’Article "Stabilite dimensionnelle".
