Vulcanized fibre for electrical purposes - Specifications for individual materials. Sheet 1. Flat sheets Ingestion-build-232773 – Range of test levels1 Scope This part of IEC 60667 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
