Proposal of transitional provisions for the 03 series of UN R51 on vehicle noise. Importantly, the proposal seeks to address the handling of transitions and extensions between the 02 and 03 series, perhaps offering a template for transitional provisions in general.
9. The expert from OICA presented GRB-55-18 introducing draft transitional provisions of the 03 series of amendments to the UN Regulation No. 51 (GRB-55-09). However, GRB did not support the proposal because it was not in line with the Revision 2 to UN Regulation No. 51 and with the general guidelines on transitional/administrative provisions (ECE/TRANS/WP.29/2011/152). The expert from OICA withdrew GRB-55-09 and GRB offered to make a proposal based on Revision 2 of Regulation 51 and the general guideline at its September 2012 session.
