ISO 17467-3:2012 specifies the physical and mechanical characteristics of fittings made from unplasticized polyamide (PA-U) in accordance with ISO 17467-1, intended to be buried and used for the supply of gaseous fuels for maximum operating pressure up to and including 4 bar.
It also specifies the test parameters for the test methods to which it refers.
ISO 17467-3:2012 also lays down requirements for dimensions and the marking of fittings.
In conjunction with ISO 17467-1 and ISO 17467-2, ISO 17467-3 is applicable to PA-U fittings, their joints and to joints with components of PA-U.
