20、out reinforcement, 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 requirementsPart 2: Methods of testPart 3: Specifications for individual materialsThis st
21、andard contains one of the sheets comprising Part 3: Sheet 8: Mica paper tapes for flame-resistant security cables.“1 ScopeThis International Standard specifies the requirements for an electrical insulating material containing mica paper with glass fabric or plastic film and impregnated with a suita
22、ble resin. The material is supplied in a flexible state. It may be supplied in the form of sheets or rolls. The product is designed for use in cables capable of operating after a fire.This specification covers material having a nominal thickness from 0,05 mm to 0,15 mm.Materials which conform to thi
23、s specification meet established 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
24、 of the user of the methods contained 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 ref
25、erences, the latest edition of the referenced document (including any amendments) applies.
