GRB | Session 66 | 4-6 Sep 2017

13. On behalf of IWG ASEP, the expert from France presented its status report to GRB (GRB-66-14). In particular, IWG ASEP had agreed to propose some improvements in the current Annex 7 as soon as possible, as laid down in ECE/TRANS/WP.29/GRB/2017/5, and then to develop a more general and strategic approach of revising Annex 7. The expert from the Russian Federation commented on ECE/TRANS/WP.29/GRB/2017/5 (GRB-66-06). GRB agreed to merge these proposals with the other proposed amendments to the 03 series of amendments to Regulation No. 51 (see para. 9 above).
