2、002+A2:2006 This British Standard, having been prepared under the direction of the Engineering Sector Policy and Strategy Committee, was published under the authority of the Standards Policy and Strategy Committee on 20 July 2002 BSI 2007 ISBN 978 0 580 59562 2 National foreword This British Standar
3、d is the UK implementation of EN 13445-4:2002 +A2:2006, incorporating corrigenda April 2003, November 2003 and July 2004. Numbered corrigenda are issued twice a year by CEN. An issue (of a page) may apply to only one of the language versions (English, French and German). Therefore the issue numbers
4、for each page in each language version may not be sequential. For future corrigenda, the index at http:/www.unm.fr/en/general/en13445 should be consulted to determine the latest edition of a page. When the reference to this European Standard has been published in the Official Journal of the European
5、 Communities (OJ), compliance with it will confer a presumption of conformity with the essential requirements covered by the standard in respect of the Pressure Equipment Directive (97/23/EC). The UK participation in its preparation was entrusted by Technical Committee PVE/1, Pressure vessels, to Su
6、bcommittee PVE/1/16, Fabrication and joining techniques. A list of organizations represented on this subcommittee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. C
