BS EN IEC 60667-3-1:2020

What is BS EN IEC 60667-3-1 about?

This International Standard is one of a series which deals with vulcanized fibre sheets for electrical purposes. BS EN IEC 60667-3-1 is the third part in a multi-series 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 BS EN IEC 60667-3-1 . 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.

Who is BS EN IEC 60667-3-1 for?

BS EN IEC 60667-3-1 on vulcanized fibre sheets for electrical purposes is relevant to:

Vulcanized fibre manufacturer Manufacturers of electrical applications that use vulcanized fibre Electrical engineers Automobile industry Construction industry

Why should you use BS EN IEC 60667-3-1 ?

Vulcanized fibres are produced by laminating plies of 100% cellulose paper after saturation phases in zinc chloride and acid baths. This manufacturing process gives this insulating material superior mechanical, insulating and electrical characteristics. BS EN IEC 60667-3 covers requirements for vulcanized fibre sheets based on properties such as thickness, apparent density, specific gravity, tensile strength, flexural strength, arc resistance, water absorption, ash content, moisture content and shrinkage. Overall, adopting specifications for vulcanized fibre sheets in compliance with BS EN IEC 60667-3
