1、BRITISH STANDARD BS EN 60455-2:1999 IEC 60455-2: 1998 Resin based reactive compounds used for electrical insulation Part 2: Methods of test The European Standard EN 60455-2:1999 has the status of a British Standard ICS 29.035.20BSEN 60455-2:1999 This British Standard, having been prepared under the

2、directionof the Electrotechnical Sector Committee, was publishedunder the authorityofthe Standards Committee and comes into effect on 15 June 1999 BSI 04-2000 ISBN 0 580 32543 1 National foreword This British Standard is the English language version of EN60455-2:1999. Itis identical with IEC 60455-2

3、:1998. It supersedes BS5664-2.1:1979 which iswithdrawn. NOTEBS 5664-2.2:1988 Coating powders, (IEC 60455-2:1984) remains current at the date of this publication, although its future is being considered by the relevant IEC committee. The UK participation in its preparation was entrusted by Technical

4、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

5、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. Fo

6、r 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. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an anne

7、x 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 Correspo

8、ndence 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 o
