This European Standard shall be given
21、the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2014, and conflicting national standards shall be withdrawn at the latest by December 2014. Attention is drawn to the possibility that some of the elements of this document may
22、be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU
23、Directive(s). For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document. This European Standard consists of the following Parts: Part 1: General. Part 2: Materials. Part 3: Design. Part 4: Fabrication. Part 5: Inspection and testing. Part 6: Requirem
24、ents for the design and fabrication of pressure vessels and pressure parts constructed from spheroidal graphite cast iron.
