WP.29/2017/56
Proposal for authorization to develop Phase 2 of GTR No. 13

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.

Excerpts from session reports
GRSP | Session 61 | 8-12 May 2017

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.

GRSP | Session 60 | 13-16 Dec 2016

10. The expert from EC introduced GRSP-60-24, on behalf of the experts from Japan and the Republic of Korea which co-sponsoring the proposal for amendments to Phase 2 of the GTR. He explained that GRSP-60-24 was a draft request to develop Phase 2 and which listed the main items to complete GTR No. 13. GRSP endorsed GRSP-60-24, as reproduced in Annex III to the session report. The secretariat was requested to submit it as an official request to develop Phase 2 of GTR No. 13 at the March 2017 sessions of WP.29 and AC.3 (ECE/TRANS/WP.29/2017/56).

WP.29 | Session 171 | 14-17 Mar 2017

162. The representative of EU introduced the proposal for authorization to develop the Phase 2 of the global technical regulation. He explained the need to start the Phase 2 to address the development of remaining issues, amongst others material qualification testing. He clarified that Japan, Republic of Korea and the European Union would sponsor the Phase 2. However, he clarified that the contribution from the United States of America, China and other Contracting Parties was encouraged and expected and that the Joint Research Centre (JRC) of the European Commission is ready to provide further relevant input.

163. AC.3 adopted ECE/TRANS/WP.29/2017/56 and requested the secretariat to convert it into an AC.3 document.
