The components of the com

26、bined materials are plastic films and/or fibrous materials such as papers, woven or non-woven fabrics, impregnated or not impregnated. This series consist of three parts describing: Part 1: Definitions and general requirements (IEC 60626-1) Part 2: Methods of test (IEC 60626-2) Part 3: Specification

28、 flexible materials for electrical insulation. This standard does not include mica paper, as primary component, covered by IEC 60371, but mica paper may be used as complementary material. Materials which conform to this specification meet established levels of performance. However, the selection of

29、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. SAFETY WARNING It is the responsibility of the user of the methods contained or referred to in this document to e

30、nsure 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 the referenced document (including any amen

31、dments) applies. NOTE The list of normative references is extensive because, in order to obtain a combination of two or more materials for electrical insulation, it is necessary that those base materials (paper, film, etc) shall conform to the requirements set forth, in the appropriate specification

32、 of the base material alone, for that purpose. This rule shall be applied also in the development of new possible combinations; to this end, specifications of materials not actually used, but referenced, may be eligible for future developments.
