Pertains to: a. The mechanical and electrical features of newly manufactured systems that dispense compressed hydrogen gas for vehicles (HGV) where such systems are intended primarily to dispense the fuel directly into the fuel storage container of the vehicle; b. HGV dispensers that integrate in a single unit multiple dispensing functions (e.g., fuel metering, registering, control and management devices, vehicle fuel cylinder overfill and over pressure protection with listed hoses with nozzles); and c. The following service pressures are applicable, 25MPa, 35MPa, 50MPa, 70MPa: Each dispenser may have the capability of independently fueling more than one vehicle simultaneously.
