This Euro

30、pean 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of an identical text or by endorsement, at the latest by December 2017, and conflicting national standards shall be withdrawn at the latest by December 2017. Attention is drawn to the possibility that some of the e

31、lements 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

32、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 EN 13480 for metallic industrial piping consists of eight interdependent and not dissociable Parts which are: Part 1: General

33、; Part 2: Materials; Part 3: Design and calculation; Part 4: Fabrication and installation; Part 5: Inspection and testing; Part 6: Additional requirements for buried piping; CEN/TR 134807, Guidance on the use of conformity assessment procedures; Part 8: Additional requirements for aluminium and alum

34、inium alloy piping. Although these Parts may be obtained separately, it should be recognised that the Parts are interdependant. As such the manufacture of metallic industrial piping requires the application of all the relevant Parts in order for the requirements of the Standard to be satisfactorily

35、fulfilled. This European Standard will be maintained by a Maintenance MHD working group whose scope of working is limited to corrections and interpretations related to EN 13480. BS EN 134804:2017EN 134804:2017 (E) Issue 1 (201706) 6 The contact to submit queries can be found at http:/www.unm.fr (en1

36、3480unm.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. Interpretatio

37、n sheets will be posted on the website of the MHD. This document supersedes EN 134804:2012. This new edition incorporates the Amendments which have been approved previously by CEN members, and the corrected pages up to Issue 4 without any further technical change. Annex Y provides details of signifi

38、cant technical changes between this European Standard and the previous edition. Amendments to this new edition may be issued from time to time and then used immediately as alternatives to rules contained herein. According to the CENCENELEC Internal Regulations, the national standards organizations o

39、f the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Net
