22. The expert from France introduced GRRF-73-03 proposing the technical report on the development of the tyre GTR. GRRF noted a number of comments. The expert from France volunteered to submit a revised proposal for consideration at the next session of GRRF as an official document.

23. The secretary of the tyre GTR informal group reported on the progress made. He presented the text of a draft GTR (ECE/TRANS/WP.29/GRRF/2012/22) which GRRF partially reviewed, taking into account the amendments proposed in GRRF-73-12, GRRF-73-13, GRRF-73-22 and GRRF-73-25. GRRF agreed that the informal group should continue to work on the draft GTR and to hold their next meeting immediately before GRRF on Monday 18 February 2013. From this meeting GRRF anticipate an updated final text for adoption during its 74th session.

21. The Secretary of the informal group for a tyre GTR reported on the progress made. He presented the latest version of the text of a draft GTR (GRRF-74-38) amending ECE/TRANS/WP.29/GRRF/2012/22. GRRF reviewed the document and agreed on the technical aspect of this proposal. GRRF noted that some decisions needed to be taken by WP.29 and AC.3. GRRF adopted ECE/TRANS/WP.29/GRRF/2012/22, as amended and reproduced in GRRF-74-38, keeping in square brackets the “Adhesion Performance on Wet Surfaces” provisions (paragraph 3.12.). GRRF requested the secretariat to submit the proposal as amended below to WP.29 and AC.3 for consideration at their June 2013 sessions and for vote at their November 2013 session. GRRF expected to review, during its September 2013 sessions any guidance received as necessary.

Paragraph 2.58., replace ASTM by ASTM International
Footnote 1, paragraph 3.14.1., amend to read:

1 Contracting Parties who utilize load ranges higher than E for LT may apply national requirements.

22. The expert from France introduced GRRF-74-09 proposing a status report on developing the tyre GTR. He volunteered to prepare an updated report as a final report for phase 1 of the development of the tyre GTR to be presented to WP.29 and AC.3 at their sessions in June 2013.

23. GRRF noted the completion of the work on the phase 1 by the informal group and acknowledged the work done by its experts.

100. The representative of the United Kingdom, Chair of the IWG on the UN GTR on Tyres, informed AC.3 that five questions were still unresolved. He confirmed that two Contracting Parties were still in the process of reviewing the text of the draft UN GTR. Referring to the final report on the development of the UN GTR (WP.29-160-09), he stated that, in the case of disagreement at the September 2013 session of GRRF, an optional test procedure should be included in addition to the two optional modules.

101. The representative of EU stated that a really long list of controversial provisions had been solved by March 2013 and, due to the five remaining unresolved questions, the UN GTR could not be adopted during the current session. He urged the Contracting Parties to make an effort to solve the pending issues at the September 2013 session of GRRF, thus allowing for voting on the draft UN GTR at the November 2013 session of AC.3.

102. The secretariat was requested to distribute WP.29-160-09 with an official symbol for consideration at the November 2013 session of AC.3.

92. The representative of the United Kingdom, Chair of the IWG on the Tyre GTR, informed AC.3 that the draft proposal ECE/TRANS/WP.29/2013/63 was not recommended for vote at this session because GRRF at its September 2013 session had not resolved the pending issues. He expressed his disappointment that it had not been possible to resolve these detailed points but remained optimistic that the GRRF session in February 2014 would finalise the GTR. He therefore, proposed to extend the mandate of IWG until June 2014. The representative of the United States of America clarified that some necessary research in his country had not be concluded on time and therefore supported the proposal to extend the mandate. AC.3 gave its consent for the extension of the mandate.

[US government shutdown delayed research on the proposed wet grip test procedures necessary before the United States can commit to the new GTR. As a result, US position should only be ready in time for discussion and finalization of draft GTR within GRRF in February 2014. This time-line suggests a vote on the GTR at the June 2014 WP.29 session.]</
