3、d is the English language version of EN60454-3-7:1998. It is identical with IEC60454-3-7:1998. The UK participation in its preparation was entrusted by Technical Committee GEL/15, Insulating materials, to Subcommittee GEL/15/3, Material specifications, which has the responsibility to: aid enquirers
4、to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represe
5、nted on this subcommittee can be obtained on request to its secretary. From1 January1997, all IEC publications have the number60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering system to the other, pu

The series consists of three parts: Part 1: General re
23、quirements (IEC60454-1); Part 2: Methods of test (IEC60454-2); Part 3: Specifications for individual materials (IEC60454-3). This standard contains one of the sheets comprising part3 as follows: Sheet7: Polyimide film tapes with pressure-sensitive adhesive. 1 General 1.1 Scope This sheet of IEC60454
24、-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 based on the actual requirements nece
25、ssary 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 IEC60454-3. At the time of publication, the editi
26、ons indicated were valid. All normative documents are subject to revision and parties to agreements based on this sheet of IEC60454-3 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below 1) .
