28、ocument (EN 13480-8:2012) has been prepared by Technical Committee CEN/TC 267 “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 la
29、test by December 2012, and conflicting national standards shall be withdrawn at the latest by December 2012.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 a
30、ll 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 o
31、f this document. This European 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: Addi
32、tional requirements for buried 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 su
33、ch 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 fulfilled. This European Standard will be maintained by a Maintenance MHD working group whose scope of working is limited to correcti
34、ons and interpretations related to EN 13480. 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 will be communicated to the questio
35、ner. 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. BS EN 13480-8:2012+A2:2015EN 13480-8:2012+A2:2015 (E) Issue 4 (2016-07) 6 This document supersedes EN 13480-8:2007+A1:2011. This new edit
36、ion incorporates the Amendments/the 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. Amendment
37、s to this new edition may be issued from time to time and then used immediately as alternatives to rules contained herein. It is intended to deliver a new Issue of EN 13480:2012 each year, consolidating these Amendments and including other identified corrections. Issue 4 (2016-07) consolidates Amend
38、ment EN 13480-8:2012/A2:2015; it includes the corrected pages listed in Annex Y. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republ
39、ic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
