European foreword
This document (CEN/TS 12007-6:2021) has been prepared by Technical Committee CEN/TC 234 “Gas
infrastructure”, the secretariat of which is held by DIN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
The basis if this document has been provided by an Ad Hoc group of interested parties consisting
variously of pipe manufacturers, material suppliers and gas network engineers. The aim is to support
the introduction of Polyamide pipe, PA-U, into Europe for use in natural gas pipe networks operating at
working pressures up to and including 16 bar. The Secretariat of the Ad Hoc group was held by NEN.
This document is part of the following series of standards, of which the parts 1 to 4 and this document
are in the responsibility of CEN/TC 234 Working Group 2, Secretariat held by BSI and of which part 5 is
in the responsibility of CEN/TC 234 Working Group 10, Secretariat held by NSAI:
— Part 1: General functional requirements
— Part 2: Specific functional requirements for polyethylene (MOP up to and including 10 bar)
— Part 3: Specific functional requirements for steel
— Part 4: Specific functional requirements for renovation
This document has been written in the style and form of the above functional EN standards, but at this
time has the status only of a CEN TS. This document will be amended under the authority of CEN/TC
234 as soon as more supporting evidence of the safe use of PA-U becomes available.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
