UNE-EN ISO 17268:2017

This International Standard defines the design, safety and operation characteristics of gaseous hydrogen land

vehicle (GHLV) refuelling connectors.

GHLV refuelling connectors consist of the following components, as applicable:

receptacle and protective cap (mounted on vehicle);

nozzle.

This International Standard applies to refuelling connectors which have working pressures of 11 MPa, 25 MPa,

35 MPa and 70 MPa, hereinafter referred to in this International Standard as the following:

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);

H70 70 MPa at 15 °C.

Nozzles and receptacles that meet the requirements of this International Standard 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 this

International Standard.

NOTE This International Standard can be used for certification purposes.
