GRB-67-01/Rev.1
UN R51: Proposal for additional amendments regarding indoor test methods (Russia)
25 Jan 2018 Working Party Informal Documents Vehicle Noise Emissions Vehicle Noise Uniform Provisions Concerning the Approval of Motor Vehicles having at least Four Wheels with regard to their Noise Emissions Proposal of amendments for inclusion with the proposals on indoor testing in document GRB/2018/3. GRB-67-0001/Rev.1
GRB-67-02
UN R92: Proposal for a Supplement 3 to the 01 series (Germany)
16 Jan 2018 Working Party Informal Documents Replacement Exhaust Silencing Systems for Motorcycles Motorcycle RESS Uniform Provisions Concerning the Approval of Non-Original Replacement Exhaust Silencing Systems (RESS) for Motorcycles, Mopeds and Three-wheeled Vehicles Proposal to introduce provisions for non-original replacement silencing systems (NORESS, independent aftermarket muffler systems) with multiple, manually or electronically adjustable, rider-selectable operating modes or variable geometries (NORESS with “flexibilities”). These "flexibilities enable the replacement systems to meet the requirements of Annex 3 (i.e., during testing) while producing much higher noise (sound pressure) outside the Annex 3 conditions. This amendment would require such NORESS to meet the ASEP requirements of UN R9 and UN R41. The amendment further introduces language taken from UN R51. In effect, NORESS with flexibilities performance under normal driving conditions would not be permitted to deviate from its performance under testing. GRB-67-0002
