INTRODUCTION This International Standard is one of a series which deals with pressure-sensitive adhesive tapes, intended primarily for electrical purpos

21、es. The series consists of three parts: - Part 1: General requirements (IEC 60454-1). - Part 2: Methods of test (IEC 60454-2). - Part 3: Specifications for individual materials (IEC 60454-3).

23、1.1 Scope This sheet of IEC 60454-3 contains the requirements for pressure-sensitive adhesive tapes made with polyimide film. 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 base

24、d on the actual requirements necessary for adequate performance in that application, and not based on this specification alone. 1.2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this sheet of IEC 60454-3. At

25、the time of publication, the editions indicated were valid. All normative documents are subject to revision and parties to agreements based on this sheet of IEC 60454-3 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below11 .
