DIN EN ISO 17268:2017-03

This European Standard defines the design, safety and operation characteristics of gaseous hydrogen landvehicle (GHLV) refuelling connectors.GHLV refuelling connectors consist of the following components, as applicable: receptacle and protective cap (mounted on vehicle); nozzle.This European Standard applies to refuelling connectors which have working pressures of 11 MPa, 25 MPa,35 MPa and 70 MPa, hereinafter referred to in this European 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 EuropeanStandard will only allow GHLVs to befilled by fuelling stations dispensing hydrogen with nominal working pressures equal to or lower than the vehiclefuel system working pressure. They will not allow GHLV to be filled by fuelling stations dispensing blends ofhydrogen with natural gas. Refuelling connectors dispensing blends of hydrogen with natural gas are excluded from the scope of this European Standard
