Annotation of standard text IEC 60667-3-1-ed.2.0 :
IEC 60667-3-1: 2020 gives requirements for vulcanized fibre sheets for electrical purposes. Materials made by combining with an adhesive several thicknesses of vulcanized fibre are not covered by this document. Materials that 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 1986. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: change to the range of thickness deviation in Table 1; addition of apparent density in Table 1; change to the range of thickness for tensile strength in Table 1; addition of flexibility and shrinkage in Table 1; change test method and property value of internal ply adhesion on Table 1. IEC 60667-3-1:2020 donne les exigences pour les feuilles en fibre vulcanisee 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 lutilisateur des methodes contenues ou mentionnees dans le present document de veiller a ce quelles soient utilisees de facon securisee. Cette deuxieme edition annule et remplace la premiere edition parue en 1986. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: modification de la plage decarts par rapport a lepaisseur dans le Tableau 1; ajout de masse volumique apparente dans le Tableau 1; modification de la plage depaisseur pour la resistance a la traction dans le Tableau 1; ajout de flexibilite et stabilite dimensionnelle dans le Tableau 1; modification de la methode dessai et de la valeur de propriete de ladherence interne du feuilletage dans le Tableau 1.
