EN 13445-8:2014 (E) Issue 1 (2014-09) 4 Foreword This document (EN 13445-8:2014) has been prepared by Technical Committee CEN/TC 54 “Unfired pressure vessels”, the secretariat of which is held by BSI. This European Standard shall 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of an identical text or by endorsement, at the latest by December 2014, and conflicting national standards shall be withdrawn at the latest by December 2014.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 document 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 requirements 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: 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 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 application 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://www.unm.fr (en13445@unm.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. Interpretation sheets will be posted on the website of the MHD. This document supersedes EN 13445-8:2009. 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 Standard and the previous edition. SIST EN 13445-8:2014

The 2nd paragraph of 4.2.2.1 of EN 13445-2:2014 is not applicable for aluminium and its alloys. The maximum design temperature shall not exceed that defined in Table 1 of EN 12392:2000 as the maximum working temperature. The mechanical properties used for design shall be taken from the tabulated values in EN 12392:2000 at room temperature for Rm/20 and at the highest design temperature for Re/T. For welded parts and heat treated parts after forming only the values equivalent to the O temper shall be used for design when 6 000 series flanges etc. are welded. These values are not quoted in EN 12392:2000 and so the tabulated values for f shown in Table 6.3-2 shall be used for design. The weld area shall be based on the O temper but the flange strength away from the weld (2t) may be based on the actual temper (T4 or T6). For aluminium and aluminium alloys values of 0,2 % proof strength (or 1 % proof strength for material group 21-1000 series aluminium) for temperatures above 20 °C shall be established by linear interpolation between two adjacent values in EN 12392:2000 except that for alloys 5083 and 5086 the respective value at 50 °C may be used for 65 °C. 6.3 Time-independent nominal design stress The design stress for aluminium and aluminium alloy materials shall be in accordance with the Table 6.3-1.
