Plastics piping systems for the supply of gaseous fuels for maximum operating pressures up to and including 2 MPa (20 bar) — Polyamide (PA) — Part 5: Fitness for purpose of the system

Systèmes de canalisations en matières plastiques pour la distribution de combustibles gazeux pour des pressions maximales de service inférieures ou égales à 2 MPa (20 bar) — Polyamide (PA) — Partie 5: Aptitude à l'emploi du système

Abstract / scope

ISO 22621-5:2010 specifies the requirements of fitness for purpose of the polyamide (PA) piping system, intended to be buried and used for the supply of gaseous fuels at maximum operating pressures (MOP) up to and including 20 bar (2 MPa).

It specifies the definitions of electrofusion and butt fusion joints.

It also specifies the method of preparation of test piece joints and the tests to be carried out on these joints for assessing the fitness for purpose of the system under normal and extreme conditions.

In addition, it specifies the test parameters for the test methods to which it refers.

In conjunction with the other parts of ISO 22621, it is applicable to PA fittings, their joints and to joints with components of PA.
