Compressed hydrogen surface vehicle refuelling connection devices
This standard has been revised by ISO 17268:2012.
ISO 17268:2006 applies to design, safety and operation verification of Compressed Hydrogen Surface Vehicle (CHSV) refuelling connection devices hereinafter referred to as nozzle and receptacle. CHSV Refuelling nozzles and receptacles consist of the following components, as applicable:
- Receptacle and protective cap (mounted on vehicle); and
ISO 17268:2006 applies to devices which have working pressures of 25 MPa and 35 MPa, hereinafter referred to as the following:
- H25 - 25 MPa at 15 °C
- H35 - 35 MPa at 15 °C
ISO 17268:2006 applies to nozzles and receptacles which (1) prevent hydrogen fuelled vehicles from being refuelled by dispenser stations with working pressures higher than the vehicle; (2) allow hydrogen vehicles to be refuelled by dispenser stations with working pressures equal to or lower than the vehicle fuel system working pressure; (3) prevent hydrogen fuelled vehicles from being refuelled by other compressed gases dispensing stations; and (4) prevent other gaseous fuelled vehicles from being refuelled by hydrogen dispensing stations.
