7. | Regulation No. 117 (Tyre rolling noise and wet grip adhesion)

12. The expert from ERTRO introduced ECE/TRANS/WP.29/GRB/2014/8 to propose new time measurement accuracy for instrumentation involved in the rolling resistance method (Annex 6 to the UN Regulation). The expert from Japan reiterated his reservation that the proposed accuracy might be too strict and asked GRB to postpone the consideration of this item to the next session. The expert from the Russian Federation agreed with this suggestion. GRB recalled that this issue had already been discussed several times and felt that a final decision should be taken at the next session. Meanwhile, experts from Japan, Russian Federation, ETRTO, as well as from other Contracting Parties were invited to finalize their consultations.

9. | Exchange of information on national and international requirements on noise levels
10. | Influence of road surface on tyre rolling sound emissions
6. | Regulation No. 117 (Tyre rolling noise and wet grip adhesion)

16. The expert from ETRTO introduced GRB-58-02, proposing new time measurement accuracy for instrumentation involved in the rolling resistance method (Annex 6 of the UN Regulation). The expert from the Russian Federation introduced GRB-58-13, arguing that this change of accuracy was not needed for Annex 6. GRB agreed to resume discussion on this subject at its January 2014 session, awaiting a revised proposal jointly prepared by the experts from the Russian Federation and ETRTO.
