- low bond with a resin content of (8 ± 3) %;
- medium bond with a resin content of (16 ± 3) %. 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. This second edition cancels and replaces the first edition, published in 1992, and constitutes a technical revision. The main changes with regard to the previous edition include adjustments needed to align this standard with changes included in the latest edition of IEC 60371-2. Keywords: electrical insulating materials, mica paper, glass fabric, vacuum pressure impregnation (VPI)
