1、BRITISH STANDARD BS EN 60243-1:1998 IEC 60243-1: 1998 Electrical strength of insulating materials Test methods Part 1: Tests at power frequencies The European Standard EN 60243-1:1998 has the status of a British Standard ICS 17.220.99; 29.035.01 Licensed Copy: sheffieldun sheffieldun, na, Thu Nov 09
2、 04:00:48 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS EN 60243-1:1998 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 April 1998 BSI 05-1999 ISBN 0 580 29776 4
3、 National foreword This British Standard is the English language version of EN 60243-1:1998. It is identical with IEC 60243-1:1998. It supersedes BS 2918-1:1994 which is withdrawn. The UK participation in its preparation was entrusted by Technical Committee GEL/15, Insulating materials, to Subcommit
4、tee GEL/15/5, Methods of test, 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 Europe
5、an 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 60 000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. Fo
6、r a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publica
7、tions with their corresponding European publications. The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find
8、” 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
9、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 18 and a back cover.
