Proposals to modify the draft Supplement 5 to UN R28:
On new para. 14.3.6.: editorial clarification. (The purpose of fixing the height should be restricted for taking measurement in a particular test.)
On para. 188.8.131.52. and para. 184.108.40.206.: Since sound level meters on the market don’t meet the latest standard yet, IMMA proposes to use same IEC standard as in ECE R51.03: IEC 61672-1:2002.
3. The expert from the Russian Federation introduced a revised proposal for amendments to Regulation No. 28 (ECE/TRANS/WP.29/GRB/2016/2, GRB-63-01 and GRB-63-04). The proposal received comments from the experts of China, France and IMMA (GRB-63-17, GRB-63-16 and GRB-63-15, respectively). The experts from Japan and Spain indicated that they would need more time to study the proposal and its consequences and requested that its adoption be postponed to the next session. GRB invited all experts to transmit their comments, before the end of March 2016, to the expert from the Russian Federation who would update the proposal for consideration at the next session.
