This website is intended to facilitate use of the standard EN 13480 by providing, at European level, an accelerated process to give official answers to questions or modification requests regarding the application of this Standard.
Information about the update and evolutions of the standard are also provided.
This information can be found at national level, from the standardization body responsible for this standard.


In 2016:

 - Publication of amendment 2 to part 2 'Materials": Revision of Table B.2-11 “Austenitic stainless steels and their lowest minimum metal temperature TM” (EN 13480-2:2012/A2:2016)

 Publication of amendment 3 to part 4 “Fabrication and installation": Revision of clauses 9.1 "Welding personnel" and 9.14.6 "Local heat treatment" (EN 13480-4:2012/A3:2016)

 - Publication of amendment 1 to part 6 “Additional requirements for buried piping": Revision of clauses A.3.5 "Global stability of a buried piping system" (EN 13480-6:2012/A1:2016)

The Issues 4 and 5 to Edition 2012 of EN 13480 is available. To get this standard,contact your national standardization body. The list of the corrected pages compared to the previous Issue is available hereafter:

The second edition of EN 13480 "Metallic Industrial Piping" has been delivered in June 2012.

This standard provides one means of conforming to essential safety requirements of the Pressure Equipment Directive 2014/68/EU (so called PED). Through the publication of its reference in the Official Journal of European Union, it gives presumption of conformity to the essential safety requirements identified in Annex ZA of each Part. EN 13480 is therefore a very important reference document in the pressure equipment sector.

Significant changes between the 2012 edition and the 2002 edition are detailed within the Annexes Y in each Part of the new Edition.

The standard consists of the following Parts:

  • 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.
  • Part 8: Additional requirements for aluminium and aluminium alloy piping.

It is completed by one informative document:

  • CEN/TR 13480-7: Guidance on the use of conformity assessment procedures.
Work organisation

The process used to deal with questions and modification requests is shown on the following diagram:

EN 13480/MHD is the central point to collect any queries from users of the standard. EN 13480/MHD is composed of European experts who were involved in the preparation of EN 13480 and any other experts nominated by CEN members.

Questions to be asked shall be written in English using the Template available on this EN 13480/MHD website.

The scope of EN 13480/MHD is limited to corrections and interpretations related to EN 13480. If EN 13480/MHD cannot solve a question, it is sent back to the relevant Working Group of CEN/TC 267.

Questions may result in technical amendments to EN 13480 which are dealt with by CEN/TC 267 according to the CEN rules (i.e. registration in CEN/TC 267 work programme, submission to vote).

The questions on EN 13480 with a proposed answer are sent by email to EN 13480/MHD experts:

  • If the question results in a 'no action' or in an 'interpretation', the author of the question is informed.
  • If the question is technical, then it is sent back to the relevant Working Group of CEN/TC 267. The author of the question is informed.
  • If the question results in a 'correction', EN 13480/MHD secretary prepares the corrected pages to be sent to CEN, for circulation to NSBs (National Standardization Bodies) as a new "Issue" of the standard. The author of the question is informed.

When questions cannot be solved by email, they are discussed during meetings of EN 13480/MHD for final validation.

The list of questions registered on EN 13480:2012 is available by downloading MHD questions of 2013 , MHD questions of 2014 , MHD questions 2015 and CENTC267_MHD questions_2016. The questions are given in a chronologic order for each Part; for the questions still under discussion, no answer is shown.

A new issue of EN 13480:2012 is delivered each year; it includes the identified corrections and consolidates the Amendments adopted between two issues. The differences between the 2012 Edition and the successive "Issues" are indicated in Annex Y of each Part of EN 13480 and the changes are indicated in the relevant pages.

The log of the corrected pages for 2016 for E-F-D versions  is available hereafter:

Every five years a consolidated Edition is published with a new year. The new Edition (so called consolidated version) is foreseen to be published in June2017.
