3、l foreword This British Standard is the official English language version of EN 13445-4:2002. 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 for each page in each langua
4、ge 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 Communities (OJ), complianc
5、e 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 Subcommittee PVE/1/16, Fabrica
