66. Agenda item 4.8.7, Regulation No. 117, ECE/TRANS/WP.29/2015/65, insert the following correction:
Annex 4, the title, footnote 1, shall read: “replace “paragraph 12.9” with “paragraph 12.8””

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

14. GRB continued its consideration of the revised proposal for new time measurement accuracy for the rolling resistance method (ECE/TRANS/WP.29/GRB/2014/8). The expert from Japan introduced several modifications to this proposal (GRB-61-06). GRB adopted the proposal, as contained in Annex V to this report, and mandated the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2015 sessions as a draft Supplement 8 to the 02 series of amendments to Regulation No. 117. GRB also noted that the Working Party on Brakes and Running Gear (GRRF), at its February 2015 session, would consider a corrigendum to Supplement 6 to the 02 series of amendments to Regulation No. 117 (ECE/TRANS/WP.29/GRRF/2015/9).

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
