Meeting Session(s)

31. The expert from Germany proposed amendments to UN Regulation No. 138 with the aim to introduce a maximum sound level for the acoustic vehicle alerting system (AVAS) at speeds greater than 20 km/h (GRBP-70-04). Following a brief discussion, the Chair invited the expert to submit a working document for consideration at the next session.


Proposal to reconcile UN R138 with UN R51 with regard to maximum sound pressure levels at speeds greater than 20 km/h by clarifying that the 75 dB(A) limit for AVAS under UN R138 concerns only the 0-20 km/h speed range.
