Full Description Preface This publication represents a standard for safe operation, substantial and durable construction and performance testing of the mechanical and electrical features of newly manufactured hydrogen gas dispensing systems for vehicles, intended primarily to dispense fuel directly into the vehicle fuel storage container. Scope This standard details mechanical and electrical features and construction of newly manufactured systems that dispense hydrogen gas for vehicles, intended primarily to dispense fuel directly into the vehicle fuel storage container. Each dispenser may have the capability of independently fueling more than one vehicle simultaneously. This standard does not apply to the nozzle; vehicle to station communication; compression and ancillary equipment; hydrogen gas storage containers; vehicle fueling appliances for HGV remote station or Kiosk consoles and remote sequencing equipment; and other remote equipment not supplied as part of the dispenser.
