11. The expert from the Netherlands recalled his earlier proposals on strengthening the tyre noise limits and reported on new developments in this field (GRB-68-27), including a proposal for the new European Regulation on General Safety. Finally, he sought consent of GRB for transforming GRB-66-03, which had proposed stricter noise limits, into a working document for the next session of GRB. The experts of Norway and CAETS generally supported the idea of reducing noise limits in UN Regulation No. 117. The expert of ETRTO recalled their comments presented at the previous session (GRB-67-08). The expert from EC pointed out that the proposal for the new European Regulation was still under discussion. For this reason, the Chair felt that it would be premature to submit an official document with the new tyres limits to the next session.
