27、h 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of an identical text or by endorsement, at the latest by December 2017, and conflicting national standards shall be withdrawn at the latest by December 2017. Attention is drawn to the p
28、ossibility 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 Tra
29、de 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 EN 13480 for metallic industrial piping consists of eight interdependent and not dissociable Par
30、ts 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 buried piping; CEN/TR 134807, Guidance on the use of conformity assessment procedures; Part 8: Additional requir
31、ements for aluminium and aluminium 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 S
32、tandard 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 related to EN 13480.

33、 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 will be communicated to the questioner. Corrected pages will be given specific issue number and issued by CEN according to
34、 CEN Rules. Interpretation sheets will be posted on the website of the MHD. This document supersedes EN 134808:2012. This new edition incorporates the Amendments/the corrigenda which have been approved previously by CEN members, and the corrected pages up to Issue 4 without any further technical cha
35、nge. Annex Y provides details of significant 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
36、, the national standards organizations of 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, L
