AS 13984:2024 adopts and modifies ISO 13984:1999, which specifies the characteristics of liquid hydrogen refuelling and dispensing systems on land vehicles of all types. The document applies to the design and installation of such systems. It also describes the system intended for the dispensing of liquid hydrogen to a vehicle, including that portion of the system that handles cold gaseous hydrogen coming from the vehicle tank
