19、inforcement, and with mica paper in its pure state for use in electrical equipment.IEC 60371 consists of three parts under the main title Insulating materials based on mica:Part 1: Definitions and general requirements Part 2: Methods of test Part 3: Specifications for individual materialsThis standa
20、rd contains one of the sheets comprising Part 3:Sheet 9: Moulding micanite.“1 ScopeThis International Standard specifies the requirements for different types of moulding micanite. They are composed of mica splittings or mica paper, with or without reinforcement, bonded with a suitable binder and may
21、 be supplied as sheets or rolls.Moulding micanites with B-stage resins are of a consistency ranging from rigid to soft. All types are mouldable when heated.This specification covers material having a nominal thickness from 0,10 mm to 7 mm.Materials which conform to this specification meet establishe
22、d levels of performance. However, the selection of a material 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.!Safety warning It is the responsibility of the user of the methods con
23、tained or referred to in this document to ensure that they are used in a safe manner.“2 Normative references!The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of
