8. Concerning the current 02 series of amendments to the UN regulation, GRB considered GRB-58-03, tabled by the expert from OICA updating the requirements on the noise test track from ISO 10844:1994 to ISO 10844:2011. GRB requested the secretariat to distribute GRB-58-03 with an official symbol at its next session.

11. GRB adopted ECE/TRANS/WP.29/GRB/2014/2, not amended, tabled by the expert from OICA to update the requirements on the noise test track from ISO 19844:1994 (i.e. Annex 8 of this Regulation) to ISO 10844:2011, as well as to incorporate transitional provisions to allow repaving of existing, non-complying test tracks with the ISO 10844:2011 standards. The secretariat was requested to submit ECE/TRANS/WP.29/GRB/2014/2 to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1), for consideration and vote at their June 2014 sessions as draft Supplement 10 to the 02 series of amendments to Regulation No. 51.

No objections to the proposal which is passed for consideration to adopt during the AC.1 session.

13. The expert from IMMA proposed to include the latest version of ISO 10844 on test tracks in UN Regulations Nos. 9, 41 and 63 and to introduce transitional provisions for passing from ISO 10844:1994 to ISO 10844:2011 (GRB-60-07). GRB supported the objective of this proposal and noted that new test tracks based on ISO 10844:2011 could also be used for extension of approvals granted under the previous series of amendments to UN Regulation No. 41. GRB invited IMMA, with the assistance of the secretariat, to revise this proposal using ECE/TRANS/WP.29/GRB/2014/2 as an example and to re-submit it as an official proposal to the January 2015 session of GRB.
