The expert from the Russian Federation reported on the work done by the group of interested experts dealing with this amendment, introducing the draft amendment 1 to GTR No.16 in ECE/TRANS/WP.29/2016/2 as well as the report contained in ECE/TRANS/WP.29/2016/3.

30. The Chair of GRRF recalled the establishment of GTR No. 16 (Tyres) in the Global Registry, the authorization to develop an amendment to GTR No. 16 (see ECE/TRANS/WP29/AC.3/42) and the sponsorship of the Russian Federation for this activity. The expert from ETRTO reported (GRRF-80-04, GRRF-80-05) and presented the status of the work done by the group of interested experts dealing with this amendment (GRRF-80-20, GRRF-80-21 and GRRF-80-22).

GRRF experts agreed to send written comments to the group of interested experts and to have a webex meeting in October, so that a formal proposal can be submitted for consideration at the February 2016 session of GRRF.
