BS EN IEC 60667-2:2020

Vulcanized fibre for electrical purposes. Methods of test

Status : Current   Published : July 2020



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
