An issue (of a page) may apply to only one of the language versions (English, French and German). Therefore the issue number
4、s 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 Europe
5、an 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).
