BRITISH STANDARD BS EN 60454-3-8:1998 IEC 60454-3-8:1998 Pressure-sensitive adhesive tapes for electrical purposes Part 3: Specifications for individual materials Sheet 8: Glass fabric with pressure-sensitive adhesive The European Standard EN 60454-3-8:1998 has the status of a British Standard ICS 29.035.30 Licensed Copy: sheffieldun sheffieldun, na, Thu Nov 09 15:34:04 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS EN 60454-3-8:1998 This British Standard, having been prepared under the direction of the Electrotechnical Sector Board, was published under the authority of the Standards Board and comes into effect on 15 October 1998 © BSI 05-1999 ISBN 0 580 30057 9 National foreword This British Standard is the English language version of EN 60454-3-8:1998. It is identical with IEC 60454-3-8:1998. 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 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 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, 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. NOTEBS 3924:1978, Specification for pressure-sensitive adhesive tapes for electrical insulating purposes, will be withdrawn after Sheets 1 to 19 (inclusive) of BS EN 60454-3 have been published.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. The 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 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 front cover, pages i and ii, the EN title page, pages 2 to 4, an inside back cover and a back cover.

This series consists of three parts: Part 1: General requirements (IEC 60454-1); Part 2: Method of test (IEC 60454-2); Part 3: Specifications for individual materials (IEC 60454-3). This standard contains one of the sheets comprising part 3 as follows: Sheet 8: Glass fabric with pressure-sensitive adhesive 1 General 1.1 Scope This sheet of IEC 60454-3 contains the requirements for pressure-sensitive adhesive tapes made with glass fabric. 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 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 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 below1).
