This European Standard shall be given the status of a national standard, either by publi
20、cation of an identical text or by endorsement, at the latest by December 2014, and conflicting national standards shall be withdrawn at the latest by December 2014.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 be the subject of patent rights. CEN and/or CENELE
21、C 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 Directive(s). For relationship with EU Directive(s
22、), 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: Requirements for the design and fabrication of pressure ve
23、ssels and pressure parts constructed from spheroidal graphite cast iron. CR 13445-7, Unfired pressure vessels Part 7: Guidance on the use of conformity assessment procedures. Part 8: Additional requirements for pressure vessels of aluminium and aluminium alloys. CEN/TR 13445-9, Unfired pressure vess
24、els Part 9: Conformance of EN 13445 series to ISO 16528 Although these Parts may be obtained separately, it should be recognised that the Parts are inter-dependant. As such the manufacture of unfired pressure vessels requires the application of all the relevant Parts in order for the requirements of
25、 the Standard to be satisfactorily fulfilled. Corrections to the standard interpretations where several options seem possible are conducted through the Migration Help Desk (MHD). Information related to the Help Desk can be found at http:/www.unm.fr (en13445unm.fr). A form for submitting questions ca
26、n be downloaded from the link to the MHD website. After subject experts have agreed an answer, the answer will be communicated to the questioner. Corrected pages will be given specific issue number and issued by CEN according to CEN Rules. Interpretation sheets will be posted on the website of the M
27、HD. This document supersedes EN 13445-2:2009. This new edition incorporates the Amendments which have been approved previously by CEN members, and the corrected pages up to Issue 5 without any further technical change. Annex Y provides details of significant technical changes between this European S
28、tandard and the previous edition.

32、ssure vessels and supports which are covered by EN 13445-1:2014 and manufactured from metallic materials; it is currently limited to steels with sufficient ductility but it is, for components operating in the creep range, also limited to sufficiently creep ductile materials . It specifies the requir
33、ements for the selection, inspection, testing and marking of metallic materials for the fabrication of unfired pressure vessels. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
