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