29. The expert from EC recalled WP.29-160-27 and WP.29-160-33, introduced at the June 2013 session of WP.29 and showing the scope for changes in the 1958 Agreement and UN Regulation No. 0, aiming at establishing an IWVTA. The expert from EC asked GRB if changes on the objectives were needed, especially, concerning UN Regulations Nos. 51 and 117. He informed GRB about the forthcoming subgroups (Subgroup on the 1958 Agreement and Subgroup on UN Regulation No. 0) meetings on IWVTA, scheduled from 11 to 13 September 2013 in Paris. The experts from ETRTO and OICA endorsed UN Regulation No. 51 inclusion at the IWVTA without splitting its provisions. The expert from ETRTO expressed concern that actually a new UN Regulation dedicated to tyre installation was still missing. GRB agreed to resume consideration on this subject at its January 2013 session awaiting the outcome of IWVTA informal group.
