scope:

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.
