This document describes the specific functional requirements for polyamide (PA) pipelines in addition to the general functional requirements of EN 12007?1 for:

  1. a maximum operating pressure (MOP) up to and including 16 bar;

  2. an operating temperature between ?20 °C and +40 °C.

This document covers one type of pipe:

  1. PA pipes single layer solid wall.

This document specifies common basic principles for gas infrastructure.

NOTE 1

Users of this document are aware that more detailed national standards and/or code of practice can exist in the CEN member countries.
