This European Standard shall

28、 be given 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of an identical text or by endorsement, at the latest by December 2014, and conflicting national standards shall be withdrawn at the latest by December 2014.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 doc

29、ument may 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 requireme

30、nts of EU 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

31、 Requirements for the design and fabrication of pressure vessels 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

32、 and aluminium alloys. CEN/TR 13445-9, Unfired pressure vessels 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 applicati

33、on of all the relevant Parts in order for the requirements of 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:/w

34、ww.unm.fr (en13445unm.fr). A form for submitting questions can 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.

35、 Interpretation sheets will be posted on the website of the MHD. This document supersedes EN 13445-4:2009. 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 det

36、ails of significant technical changes between this European Standard and the previous edition.
