| Subject of the standard: | This document specifies the characteristics of valves made from unplasticized polyamide (PA-U) in accordance with ISO 16486-1, intended to be buried and used for the supply of gaseous fuels. NOTE 1 For the purpose of this document the term gaseous fuels include for example natural gas, methane, butane, propane, hydrogen, manufactured gas, biogas, and mixtures of these gases. Additional information about the suitability for 100 % hydrogen and its admixtures with natural gas is given by ISO 16486-1:2023, Annex C and Annex D. It is applicable to isolating unidirectional and bi-directional valves with spigot ends or electrofusion sockets intended to be fused with PA-U pipes conforming to ISO 16486-2 and PA-U fittings conforming to ISO 16486-3. This document also specifies the test parameters for the test methods it describes. In conjunction with ISO 16486-1, ISO 16486-2, ISO 16486-3 and ISO 16486-5, this document is applicable to PA-U valves and ... |
