3. Through a presentation (GRB-60-16), the expert from OICA introduced ECE/TRANS/WP.29/GRB/2014/4 proposing amendments to UN Regulation No. 28, in particular, a reduction the prescribed sound level of the audible warning device from 93 to 87 dB(A). While the expert from the Republic of Korea supported this proposal, the experts from India and IMMA requested a study reservation. GRB agreed to revert to this issue at its January 2015 session. |
