10、Pressure Equipment Directive). Once the standard is cited in the Official Journal of the European Communities under that directive and has been implemented as a national standard in at least one Member State, compliance with the clauses of this standard given in Table ZA.1 confers, within the limits

11、 of the scope of this standard, a presumption of conformity with the corresponding essential requirements of that directive and associated EFTA regulations. Amendments This standard differs from DIN EN 1866:2006-03 as follows: a) the standard has been divided into three parts; b) the Foreword has be

12、en revised and references to the Pressure Equipment Directive, Directive 97/23/EC of the European Parliament and of the Council of 29 May 1997 on the approximation of the laws of the Member States concerning pressure equipment have been deleted; c) requirements for pressure-containing parts in accor

13、dance with the Pressure Equipment Directive (Directive 97/23/EEC) have been deleted and are now included in DIN EN 1866-2 (currently at draft stage) and DIN EN 1866-3, Annex ZA “Relationship between this European Standard and the essential requirements of EU Directive 97/23/EC”; d) some terms and de

14、finitions, as well as some symbols and abbreviations have been modified; e) specifications regarding characteristics and fire performance have been revised and are included in DIN EN 1866-1; f) requirements for mobile CO2extinguishers have been included; g) requirements for the pressure resistance o
