It is identical with IEC 60454-3-12:1998. The UK participation in its preparation was entrusted by Technical Committee
4、GEL/15, Insulating materials, to Subcommittee GEL/15/3, Material specifications, which has the responsibility to: aid enquirers 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
5、informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance
6、, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems.

7、 withdrawn after Sheets 1 to 19 (inclusive) of BS EN 60454-3 have been published. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding European publications. Th
8、e British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence “Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does
9、not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside

25、h deals with pressure-sensitive adhesive tapes, intended primarily for electrical purposes. 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). This standard contains one
26、 of the sheets comprising part 3 as follows: Sheet 12: Polyethylene film tapes with pressure-sensitive adhesive. 1 General 1.1 Scope This sheet of IEC 60454-3 contains the requirements for polyethylene film tapes with pressure-sensitive adhesive. Materials which conform to this specification meet es
27、tablished levels of performance. However, the selection of a 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. 1.2 Normative references The following normative do
28、cuments contain provisions which, through reference in the text, constitute provisions of this sheet of IEC 60454-3. At the time of publication, the editions indicated were valid1). All normative documents are subject to revision and parties to agreements based on this sheet of IEC 60454-3 are encou
