This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 267.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

European foreword
This document (prEN 13480-9:2018) has been prepared by Technical Committee CEN/TC 267
“Industrial piping and pipelines”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
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 of this
document.
This European Standard EN 13480, Metallic industrial piping, consists of nine 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;
— Part 7: Guidance on the use of conformity assessment procedures [CEN/TR];
— Part 8: Additional requirements for aluminium and aluminium alloy piping;
— Part 9: Additional requirements for nickel and nickel alloys piping.
Although these parts may be obtained separately, 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 European 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 the EN 13480 series.
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.
