Foreword

This document (EN 13480-3:2012) 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of an identical text or by endorsement, at the latest by December 2012, and conflicting national standards shall be withdrawn at the latest by December 2012.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 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 essential requirements of EC Directive(s).

For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this document.

In this European Standard the Annexes A, C, F, G, I, K, L, M, P and Q are informative and the Annexes B, D, E, H, J, N and O are normative.

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: Additional 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 interdependent. 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 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.

The contact to submit queries can be found at http://www.unm.fr (en13480@unm.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. Interpretation sheets will be posted on the website of the MHD.

Significant technical changes include:

� Addition in clause 2 of normative references related to the types of inspection documents for metallic products and qualification of welding procedures for metallic materials.

� Revision of 5.3.2.1 concerning the design conditions related to the time-dependent nominal design stress, of 6.6 related to the bolted flange connections, of clause 8 related to openings and branch connections, of clause 11 related to integral attachments and of clause 13 related to supports.

� Revision of the Annex B related to more accurate calculation of bends and elbows.

� Revision of the Annex H related to the flexibility characteristics, flexibility and stress intensification factors and section moduli of piping components and geometrical discontinuities.

� Revision of the Annex L related to the buckling of linear type supports.

� Revision of the Annex N related to the documentation of supports.

� Addition of the new Annex O related to the alternative method for checking branch connections.

� Addition of the new Annex P related to the bolted flange connections (application of the European Standard concerning the calculation method for the design rules for gasketed circular flange connections).

� Addition of the new Annex Q related to the simplified pipe stress analysis.

� Revision of the Annexe ZA in relation with the Pressure Equipment Directive 97/23/EC.
