WP.29/2013/55: Based upon a proposal from the ETRTO and the UK, this text was adopted by the Working Party on Noise (GRB) at its 57th session to update noise test-track requirements from ISO 19844:1994 to ISO 10844:2011 and incorporate transitional provisions to allow repaving of existing, non-compliant test tracks with the ISO 10844:2011 standards.

WP.29/2013/59: Text as adopted by the Working Party on Brakes and Running Gear (GRRF) at its 74th session based upon a European Tyre and Rim Technical Organisation (ETRTO) proposal to amend the snow test method for C3 tyres in order to prescribe the wider of the possible speed ranges (document GRRF/2012/19). Please note that this proposal was adopted at the November 2013 (161st) WP.29 session as Supplement 5, having originally been proposed as Supplement 4 during the June session.

[The World Forum agreed to keep this proposal on the agenda for consideration at its November 2013 session pending reconfirmation of the proposed limit values by GRRF at its September 2013 session.]
26. The expert from ETRTO presented GRRF-75-02, justifying the wet grip limit values for C3 tyres specified in ECE/TRANS/WP.29/2013/66. Following a tour de table, the Chair noted that half the experts were in favour of amending the proposed limits for normal and traction tyres whilst retaining the proposed limits for snow and special use tyres, while the other half were in favour of maintaining those proposed in ECE/TRANS/WP.29/2013/66. The GRRF Vice-Chair volunteered to lead a discussion with interested experts on a proposal for GRRF at its next session. GRRF preferred to postpone the vote by WP.29 and AC.1 on ECE/TRANS/WP.29/2013/66 until their June 2014 sessions.
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.
55. The World Forum considered the pending proposal for amendments to Regulation No. 117 listed under agenda item 4.12.3 (document ECE/TRANS/WP.29/2013/66) and recommended its submission to AC.1 for voting, subject to the correction of para. 47 below (see WP.29-162-05).
56. Page 1, the title, replace “Supplement 5” by “Supplement 6”. Page 2, paragraph 6.2.3, correct the wet grip index G for normal tyres other than traction tyres to read 0.80.
[The proposal was adopted as amended as “Supplement 6 to the 02 series of amendments to UN Regulation No. 117” by a vote of 36 in favor and none either opposed or abstaining.]
24. Recalling the purpose of ECE/TRANS/WP.29/2013/66, the Chair of GRRF stressed that WP.29 was expecting GRRF to conclude its deliberation about the wet grip limit values. The GRRF experts introduced their positions (GRRF-76-05, GRRF-76-07, GRRF-76-08, GRRF-76-11, GRRF-76-12, GRRF-76-26, GRRF-76-27, GRRF-76-28). The expert from the EC reported on the concerns expressed by the Directorate-General for Mobility and Transport of the European Commission (DG Move). GRRF confirmed the limit values proposed in para. 6.2.2. for Tyres of C2 category and agreed to amend the proposed limit values in para. 6.2.3. for Tyres of C3 category in ECE/TRANS/WP.29/2013/66. GRRF requested the secretariat to submit this amendment as reproduced in WP.29-162-05 to WP.29 and AC.1 for consideration at their March 2014 session.
24bis. The expert from the Russian Federation presented GRB-59-02 proposing a tyre rolling resistance test results evaluation using a mathematical algorithm, to be added as an alternative to the existing one in the text of the Regulation. He also presented the results of a validation study of the proposed algorithm for tyres of the C1 category performed in France, in cooperation with the Russian Federation (GRB-59-07 and GRB-59-08). GRRF noted that this proposal may be submitted by GRB to WP.29 as a supplement to UN Regulation No. 117. GRRF recommended further steps for a better understanding of the proposed method’s sensitivity, suggesting: (i) extending the validation study for tyres of categories C2 and C3 and (ii) verifying the application of the proposed alternative in the conditions of the conformity of production. The GRRF Chair invited the experts to provide their comments on the proposal to the GRB secretariat with a copy to the expert from the Russian Federation.

WP.29/2015/5: Proposal as approved by the GRB to introduce a “Deceleration Calculator” (dω/dt) for use in the UN R117 test procedures. This procedure was developed by Russia and validated by an ad hoc group (including NAMI, UTAC, and ETRTO). This proposal also includes clarifications concerning snow tire markings approved by the GRRF during its 78th session.
