ISO 17268 document is applicable to refuelling connectors that have nominal working pressures or hydrogen service levels up to 70 MPa. It details best practices for designing, safety and operation characteristics of gaseous hydrogen land vehicle (GHLV) refuelling connectors.
GHLV refuelling connectors consist of the following components, as applicable:
NOTE: ISO 17268 is not applicable to refuelling connectors dispensing blends of hydrogen with natural gas.
ISO 17268 on gaseous hydrogen land vehicle refuelling connection devices is useful for:
Nozzles and receptacles defined in ISO 17268 can be used to fuel different types of GHLVs.
The refuelling stations for these vehicles may have significantly different process limits and refuelling protocols.
ISO 17268 is beneficial for clear instructions on the required maintenance and required periodic inspection of components as well as the expected service life of the receptacle and nozzle including the expected service life of components, if different.
Overall, ISO 17268 provides a test procedure to verify that the nozzle, receptacle, receptacle check valve and connector can withstand durability cycling. This will help you to ensure the safety, design and operation characteristics of GHLV.
