25、95 BSI 2007 3Introduction!This International Standard is one of a series which deals with insulating materials for use in electrical equipment built up from mica splittings or mica paper, with or without reinforcement, and with mica paper in its pure state. The series consists of the following three

26、 parts: Part 1: Definitions and general requirements (IEC 60371-1) Part 2: Methods of test (IEC 60371-2)Part 3: Specifications for individual materials (IEC 60371-3)This standard contains one of the sheets comprising part 3, as follows: Sheet 6: Glass-backed mica paper with a B-stage epoxy resin bin

27、der.“ 1 ScopeThis International Standard gives requirements for electrical insulating materials made by combining mica paper with glass fabric and impregnating the mica paper with an epoxy resin. The material is supplied in a flexible state with the resin in the B-stage for final cure after applicat

28、ion. It may be supplied in the form of sheets or rolls.The specification covers material having nominal thickness from 0,09 mm to 0,28 mm.!Materials which conform to this specification meet established levels of performance. However, the selection of materials by a user for a specific application sh

29、ould be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. Safety warning: It is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner.“ 2 N
