Gaseous hydrogen land vehicle refuelling connection devices
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:
(a) Receptacle and protective cap (mounted on vehicle);
(b) Nozzle;
(c) Communication hardware.
This document is applicable to refuelling connectors which have nominal working pressures or hydrogen service levels up to 70 MPa. It is not applicable to refuelling connectors dispensing blends of hydrogen with natural gas.
This standard was prepared by the P3652 Hydrogen Standards Committee and is identical to and has been reproduced from ISO 17268:2020, Gaseous hydrogen land vehicle refuelling connection devices.
