| Summary | The current UN R28 test procedures specify voltages that cannot be reached by many vehicles' internal battery charges alone; however, the provisions can be met if the vehicle is warmed up and run at idle. Therefore, OICA proposes to allow vehicles to be run at idle during the test procedure. OICA also proposes to change the minimum sound level requirement for vehicles of category M and N and motorcycles of a power greater than 7 kW from 93 dB to 87 dB. | ||||||||

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. |
