UN R51: Proposal for a Supplement 10 to the 02 series of amendments
Reference Number: WP.29/2014/44
Proposal originally by OICA (document GRB/2014/2) to update requirements for the noise test track from ISO 19844:1994 (i.e. Annex 8 of this Regulation) to ISO 10844:2011 and to allow for repaving of existing, non-compliant test tracks to meet the ISO 10844:2011 standards as adopted by the Working Party on Noise (GRB) at its 59th session. This change concerns the measurement of vehicle passing noise.
