6. See also, para. 20, concerning the updating of the requirements on the noise test track from ISO 10844:1994 to ISO 10844:2011, GRB agreed to defer discussion on ECE/TRANS/WP.29/GRB/2012/16 and ECE/TRANS/WP.29/GRB/2012/17 to its February 2013 session.

7. The expert from OICA introduced ECE/TRANS/WP.29/GRB/2012/8, consolidating a proposal of 03 series of amendments to UN Regulation No. 51. The proposal received comments from the expert of ETRTO (GRB-56-16) proposing to change the vehicle test conditions of Annex 10 of UN Regulation No. 51. GRB noted that the proposed changes (GRB-56-16) have already been adopted as Supplement 8 to the 02 series of amendments and agreed to amend ECE/TRANS/WP.29/GRB/2012/8 accordingly. Moreover, the expert from the Netherlands introduced GRB-56-12 proposing a new layout for the communication form. GRB agreed to resume consideration at its February 2013 session on ECE/TRANS/WP.29/GRB/2012/8 on the basis of a revised document prepared by the expert from the Netherlands in cooperation with the experts from CLEPA and OICA. GRB recommended experts to provide detailed comments.

8. GRB considered and adopted GRB-56-03 as reproduced in Annex II to this report, amending the figure for measuring positions of vehicles in motion. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration at their March 2013 session as Supplement 9 to the 02 series of amendments to UN Regulation No. 51.

9. Finally GRB considered GRB-56-06, tabled by the expert from China, introducing amendments to the test method. He introduced GRB-56-09 for information, showing the difference among the test methods in UN Regulation No. 51, ISO 362 and the Chinese standard (GBI1495-2002) and GRB-56-22 as a justification to the proposed amendments to the test. The expert from OICA suggested that such relevant outcome of research should be brought together with those from other Contracting Parties to the 1958 Agreement (i.e. European Union) to keep UN Regulation No. 51 relevant worldwide. GRB agreed to resume discussion at the February 2013 session on a possible official proposal (based on GRB-56-06) tabled by the expert from China in cooperation with the expert from ISO.
