Abstract

ISO 17268:2012 defines the design, safety and operation characteristics of gaseous hydrogen land vehicle (GHLV) refueling connectors consisting of, as applicable, a receptacle and a protective cap (mounted on vehicle), and a nozzle.

It applies to refueling 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 fueling 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 fueling stations dispensing blends of hydrogen with natural gas.

Refueling connectors dispensing blends of hydrogen with natural gas are excluded from the scope of ISO 17268:2012.


Status

The 2nd edition was re-titled and published in 2012 as ISO 17268:2012. Available through ISO, ANSI and CGA.


The F
inal Draft International Standard for the 3rd edition has been approved.

 

The next edition will limit revisions to H70 high flow.
