    This European Standard was approved by CEN on 23 May 2002.

    CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this EuropeanStandard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Management Centre or to any CEN member.

    This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the officialversions.

    CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

    Foreword

    This document (EN 13480-2:2002) has been prepared by Technical Committee CEN/TC 267 "Industrial piping andpipelines", 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of an identical text orby endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latestby November 2002.

    This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree 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 of this document.

    In this standard the Annexes A, B and C are normative.

    This European Standard EN 13480 for metallic industrial piping consists of seven interdependent and not dissociableParts which are:

    Part 1: General.

    Part 2: Materials.

    Part 3: Design.

    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.

    According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.

    1 Scope

    This Part of this European Standard specifies the requirements for materials (including metallic clad materials) forindustrial piping and supports covered by EN 13480-1 manufactured from of metallic materials. It is currently limited tosteels with sufficient ductility.

    NOTE Other materials will be added later by amendments.

    It specifies the requirements for the selection, inspection, testing and marking of metallic materials for the fabricationof industrial piping.
