CSA HGV 4.3-2012 Test Methods For Hydrogen Fueling Parameter Evaluation.
Part IV: Definitions
AMBIENT TEMPERATURE: The outside air temperature measured at or near the dispenser.
APPROVED: Acceptable to the authority having jurisdiction.
APPROVED STANDARD: A standard which is acceptable to the authority having jurisdiction
APPROVAL: Approved by, or approval of, the Regulatory Authority.
AUTHORITY HAVING JURISDICTION: The organization, Regulatory Authority, office or individual
responsible for approving equipment, an installation or a procedure.
BREAKAWAY DEVICE: A component installed downstream of the dispenser outlet connection to protect
the dispenser assembly from damage by vehicles driving away while still connected to the dispenser
BUFFER: storage buffers on a fueling station may be sequentially equalized with the vehicle during the
fueling process
CERTIFICATION AGENCY: An impartial body possessing the necessary competence and reliability to
operate a certification system and in which the interests of all parties concerned with the functioning of
the system are represented.
CERTIFIED: (With respect to any accessory, component, equipment, or manufacturer’s installation
instructions) investigated and identified by a nationally recognized testing and certification agency as
conforming to recognized standards or requirements or accepted test reports.
COMMUNICATION / NON-COMMUNICATION FUELING: SAE TIR J2601 compliant dispensers shall be
able to fuel vehicles with or without the optional SAE }-2799 hardware present or functional. The SAE TIR
J2601 non-communication fueling tables assume that the vehicle tank may be in a hot soak or cold soak
condition and may provide a slightly lower soc at the end of a fueling event than if the communication
link between the vehicle and dispenser is present and working correctly. If the communication link fails
during the fueling event, the dispenser shall end the fueling event at the non-communication fueling
Target Fill Pressure
DATA COMMUNICATION LINK: The optional data communication method specified by SAE |2799
consists of an infrared emitter that is mounted on the hydrogen surface vehicle (HSV) in close proximity to
the receptacle and infrared receivers that are located in the nozzle. The IRDA link allows the hydrogen
surface vehicle (HSV) to send data to the fuel dispensing system.CSA HGV 4.3 pdf download.
