Status and Path Forward
• ISO TR 19880-1 passed P-Member ballot in October, 2015. Published in first quarter 2016
• ISO WG 24 is working to harmonize fueling validation with CSA, SAE & ISO and is working with the state of California.
• International Standard ISO 19880-1 Planned to finish by the end of 2016.
• ISO IS 19880-1 to be used as a basis for the European CEN H2 StationStandard which is planned to be used in the Alternative Fuels Directive(replacing ISO TS 20100).
• ISO 19880-1 is to be used as a basis for infrastructure in Europe includingthe 400 recently announced in Germany and 50+ European fundedstations starting in 2017- and other countries such as Japan, China, andreference in the US.

Fueling Components Updated Cycle Requirements
A fueling assembly should consist of a breakaway device, a hose(s), a nozzle and connectors between these components.
Suitability of the fueling assembly components for the specified service conditions and cycle life should be demonstrated by type testing. Type testing to enable a rated pressure to MAWP could for example include:
• a hydrostatic pressure test to 375 % NWP;• 100,000 pressure cycles to 125 % NWP; • 190 pressure cycles to 150 % NWP.
ISO TS 20100ISO 19880-1
Different Direction from previous ISO TS 20100:
• Detailed guidance on hydrogen dispensing. Reference SAE J2601 as possible means of fueling.
• More detailed guidance on the acceptance process (both safety and performance aspects)
• Study into variation of existing safety distances used currently around the world
Issues trying to address:
• Interaction between vehicle and dispenser – what is the minimum acceptable reliability of fueling control (Risk Assessment Approach).
• Understanding of Limits on dispensing pressures internationally, specifically the EU – what is needed to enable station side component filling of a vehicle 125 % NWP (not possible in EU currently). Goal to raise PRV setting to 138% NWP.
• Hydrogen quality – how to control quality without burdening stations with excessive, unnecessary analysis requirements (leading to creation of new WG 28 in ISO TC 197)
• Safety distances – status and trying to find consensus on an approach that is suitable for countries where there are currently very different methodologies in place
Dispensing Components and Fueling Protocol Pressure Mismatch
• Some fueling protocols go to a pressure of 125% during filling, however European dispenser components only rated to 125 % NWP.
• PRV needs to be set at the so-called “rated pressure” in Europe
• In the EU, this precludes fueling to 125 % NWP where PRVs are used as the over-pressure protection in case of the dispenser basic control system failure
