Application Summary AI generated
This standard specifies the technical requirements, test methods, and inspection rules for pressure relief valves (PRVs) used in LNG fuel systems of road vehicles. It is applied to ensure that PRVs reliably vent excess pressure to prevent system rupture or explosion under overpressure conditions, such as during thermal expansion or regulator failure. The standard is relevant for manufacturers, testing laboratories, and regulatory bodies involved in the design, production, and certification of LNG-powered trucks, buses, and other commercial vehicles.
