What is BS EN 60641-3-1 - Requirements for pressboard for electrical purposes about?
BS EN 60641-3-1 is the international standard that gives the requirements for pressboard for electrical purposes comprised of 100 % sulphate wood pulp or a mixture of sulphate wood pulp and cotton.
Materials that conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not
based on this specification alone.
