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.
