8. The expert from Japan informed GRSP that the request for authorization (ECE/TRANS/WP.29/2017/56) had been endorsed by AC.3 at its March 2017 session and that AC.3 had invited all experts to contact the co-sponsors to participate in the activities of the IWG that would likely to start late 2017 with a completion expected by the end of 2020. The expert from EC underlined the importance of Phase 2 of the UN GTR to solve the lack of harmonization of material qualification of containers. He added that this legislative void would create bottlenecks to technical progress. The Chair of GRSP encouraged all Contracting Parties and technical experts to participate in the IWG and to share research data and testing on material compatibility as well as other technical items in phase 2 that would enable development of robust provisions.

Proposal for the Phase 2 development of GTR No. 13, including - Further consideration of items in the original authorization (document WP.29/AC.3/17);
- Potential revision of the scope to address additional vehicle classes;
- Requirements for material compatibility and hydrogen embrittlement;
- Requirements for the fueling receptacle;
- 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);
- 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 Nominal Working Pressure (NWP) or lower as the minimum burst requirement; and
- Consider Safety guard system for the case of isolation resistance breakdown.
