Laminated pressboard for electrical purposes - Part 3: Specifications for individual materials - Sheet 1: Requirements for laminated precompressed pressboard, Types LB3.1A.1 and LB3.1A.2
This sheet of IEC 60763-3 gives the requirements for laminated precompressed boards comprised of 100 % sulphate wood pulp. Materials which 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.
