What is BS EN IEC 60667-2 about?
This International Standard is one of a series which deals with vulcanized fibre sheets for electrical purposes.
BS EN IEC 60667-2 is the second part in a multi-series of documents 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 BS EN IEC 60667-2.
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 60667-2 for?
BS EN IEC 60667-2 on vulcanized fibre for electrical purposes applied for the following:
- Vulcanized fibre manufacturer
- Manufacturers of electrical applications that use vulcanized fibre
- Electrical engineers
- Automobile industry
- Construction industry
Why should you use BS EN IEC 60667-2?
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 60667-2 covers requirements and conditions for density, thickness, tensile strength and elongation, flexural strength, water absorption, arc resistance, ash content, water content and bending, to conduct the tests.
Overall, adopting requirements and guidelines in compliance with BS EN IEC 60667-2 can help establish standardised production processes that impart credibility and reliability for your products. The use of high-quality vulcanized fibre for electrical purposes can enhance the performance and service-life of the end-use application. Regular testing helps in discovering potential future failures before they happen.
What’s changed since the last update?
BS EN IEC 60667-2:2020supersedes BS 6091‑2:1987, which is withdrawn. Some of the changes are:
- Added Terms and definitions
- Added General notes on tests
- Added Thickness instead of dimension
- Changed Apparent density from Density
- Added Arc resistance
