14、67 “Industrial piping and pipelines”, the secretariat of which is held by AFNOR. 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 2012, and conflicting national standards shall be withdraw

15、n at the latest by December 2012. 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 give

16、n 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. In this European Standard Annex A is informative. This Eur

17、opean Standard EN 13480 for metallic industrial piping consists of eight interdependent and not dissociable Parts which are: Part 1: General; Part 2: Materials; Part 3: Design and calculation; Part 4: Fabrication and installation; Part 5: Inspection and testing; Part 6: Additional requirements for b

18、uried piping; CEN/TR 13480-7, Guidance on the use of conformity assessment procedures; Part 8: Additional requirements for aluminium and aluminium alloy piping. Although these Parts may be obtained separately, it should be recognised that the Parts are inter-dependant. As such the manufacture of met

19、allic industrial piping requires the application of all the relevant Parts in order for the requirements of the Standard to be satisfactorily fulfilled. This European Standard will be maintained by a Maintenance MHD working group whose scope of working is limited to corrections and interpretations r

20、elated to EN 13480. BS EN 13480-1:2012EN 13480-1:2012 (E) Issue 3 (2014-08) 4 The contact to submit queries can be found at http:/www.unm.fr (en13480unm.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 wi

21、ll 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 13480-1:2002+A1:2005+A2:2007. This new edition incorporates the Amendments/t

22、he corrigenda which have been approved previously by CEN members, and the corrected pages up to Issue 17 without any further technical change. Annex Y provides details of significant technical changes between this European Standard and the previous edition. Amendments to this new edition may be issu
