30. The Chair of GRRF, Mr. B. Frost, informed WP.29 about the results achieved by GRRF during its seventy-fifth session (for more details, see the report of the session ECE/TRANS/WP.29/GRRF/75).

31. The Chair of GRRF reported on the progress made by GRRF to completely redraft the transitional provisions of Regulations Nos. 13 and 13-H and to harmonize them with the corresponding guidelines.

32. The Chair of GRRF reported that GRRF was still seeking a consensus proposal on new wet grip limits for tyres of category C3 in ECE/TRANS/WP.29/2013/66 (Supplement 5 to the 02 series of amendments to UN Regulation No. 117) and proposed WP.29 and AC.1 to defer the vote.

33. The Chair of GRRF requested authorization for the informal working group on the Tyre GTR to hold an additional meeting for consideration of a proposal by the experts from China on the “bead unseating test” and of potential findings from research associated with the wet grip test performed by the United States of America. WP.29 gave its consent to that request, subject to the confirmation by AC.3 (see para. 92).

34. The World Forum noted that Mr. Frost (UK) and Mr. Kubota (Japan) had been re-elected Chair and Vice-Chair of GRRF for the sessions in 2014.
