ISO 17268:2012 defines the design, safety and operation characteristics of gaseous hydrogen land vehicle (GHLV) refuelling connectors consisting of, as applicable, a receptacle and a protective cap (mounted on vehicle), and a nozzle.
It applies to refuelling connectors which have working pressures of 11 MPa, 25 MPa, 35 MPa and 70 MPa, referred to as
H11 - 11 MPa at 15 °C,
H25 - 25 MPa at 15 °C,
H35 - 35 MPa at 15 °C,
H35HF - 35 MPa at 15 °C (high flow for commercial vehicle applications), and
H70 - 70 MPa at 15 °C.
Nozzles and receptacles that meet the requirements of ISO 17268:2012 will only allow GHLVs to be filled by fuelling stations dispensing hydrogen with nominal working pressures equal to or lower than the vehicle fuel system working pressure. They will not allow GHLV to be filled by fuelling stations dispensing blends of hydrogen with natural gas.
Refuelling connectors dispensing blends of hydrogen with natural gas are excluded from the scope of ISO 17268:2012.
