UN R138: Proposal for Supplement 2 to the 01 series of amendments
Reference Number: GRBP-70-04
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.
