Draft proposal for eventual submission to WP.29 for the further development of the GTR on hydrogen fuel-cell vehicle safety, including the following additional areas for consideration:

1. Scope revision to address additional vehicle classes;
2. Requirements for material compatibility and hydrogen embrittlement;
3. Requirements for the fuelling receptacle;
4. Evaluation of performance-based test for long-term stress rupture proposed in Phase 1;
5. Consideration of research results reported after completion of Phase 1 – specifically research related to electrical safety, hydrogen storage systems, and post-crash safety;
6. Consideration of 200 per cent NWP or lower as the minimum burst requirement;
7. Safety guard system for the case of isolation resistance breakdown.

Proposal for the Phase 2 development of GTR No. 13, including

1. Further consideration of items in the original authorization (document WP.29/AC.3/17);
2. Potential revision of the scope to address additional vehicle classes;
3. Requirements for material compatibility and hydrogen embrittlement;
4. Requirements for the fueling receptacle;
5. Evaluation of performance-based test for long-term stress rupture proposed in Phase 1 (including assessment of a procedure to evaluate the risk of long-term stress rupture of storage containers made from composite fiber reinforced polymers);
6. Consideration of research results reported after completion of Phase 1 – specifically research related to electrical safety, hydrogen storage systems, and post-crash safety;
7. Consideration of 200 per cent Nominal Working Pressure (NWP) or lower as the minimum burst requirement; and
8. Consider Safety guard system for the case of isolation resistance breakdown.
