This document specifies the general properties of unplasticized polyamide (PA-U) compositions for the manufacture of tubes, fittings and valves made from the composition, intended to be buried and used for the distribution of gaseous fuels. It also specifies the test parameters for the test methods it refers to. The ISO 16486 series applies to PA-U pipeline systems whose components are connected by welding assemblies and/or by mechanical assemblies. This document establishes a calculation and design scheme on which to base the maximum working pressure (MOP) of a PA-U pipeline system.
