17. The expert from Japan, Chair of the informal working subgroup safety (SGS) and the expert from the United States introduced the most draft UN GTR on hydrogen and fuel cell vehicles ECE/TRANS/WP.29/GRSP/2012/23, superseding ECE/TRANS/WP.29/GRSP/2012/12 and the final status report (GRSP-52-08) of SGS. The expert from the United States of America stated that the application of the current proposal of the UN GTR addressing passenger vehicles and three main systems: (i) fuel system integrity, (ii) electrical safety and (iii) hydrogen storage systems. The expert from the United States clarified that Phase 2 of the UN GTR would address the performance requirements of containers of any kind (i.e. liquefied hydrogen, cryo-compressed hydrogen (CcH2)) and harmonized types of crash tests (rear, front and lateral). He clarified that Contracting Parties, adopting this first phase of the UN GTR may apply crash tests standards in use in their national legislations to verify post-crash integrity of the three vehicle systems mentioned above.

18. GRSP adopted the final progress report of SGS (GRSP-52-08), as reproduced in Annex III to this report. GRSP agreed to remove the square brackets from paras. 5.3.1.2.4.3. and 5.3.2.2.3. and to recommend ECE/TRANS/WP.29/GRSP/2012/23 not amended and the final progress report to AC.3 for consideration and vote at its June 2013 session.
