Possible amendments to the Consolidated Resolution on the Construction of Vehicles
17 Jan 2014 Working Party Informal Documents Consolidated Resolution on the Construction of Vehicles Consolidated Resolution RE3 Consolidated Resolution on the Construction of Vehicles (R.E.3) Vehicle Noise Emissions Vehicle Noise Uniform Provisions Concerning the Approval of Motor Vehicles having at least Four Wheels with regard to their Noise Emissions Motorcycle Noise Motorcycle Noise Uniform Provisions Concerning the Approval of Motor Cycles with regard to Noise Two-wheeled Moped Noise Moped Noise Uniform Provisions Concerning the Approval of Two-wheeled Mopeds with regard to Noise Proposal by the WP.29 secretariat to consider amending the Consolidated Resolution to adhere with provisions of the UN Regulations concerning noise limits. Presently, the resolution (which provides a framework and general reference for UN Regulations) permits a 5 db(A) tolerance in measuring noise levels while the UN Regulations 51, 41 and 63 referred to in the resolution permit narrower margins of 1 db(A) or 3 db(A).

Proposal for Supplement 5 to the 02 series of amendments to UN Regulation No. 117 (Russia)
17 Jan 2014 Working Party Informal Documents Tire Rolling Sound Emissions, Adhesion on Wet Surfaces, and Rolling Resistance Tire Noise, Wet Adhesion, and Rolling Resistance Uniform provisions concerning the approval of tyres with regard to rolling sound emissions and/or to adhesion on wet surfaces and/or to rolling resistance The Russian Federation has developed a "Deceleration Calculator" for use in the UN R117 procedures. Following work by an ad hoc group (including NAMI, UTAC, and ETRTO) formed to review and validate this tool, Russia has prepared this new proposal, modifying the version (document GRB/2013/10) submitted at the last GRB session. The changes primarily concern the explanation of the tool rather than the basic mathematical equations. GRB-59-0002
GRB-59-03
Proposal for amendments to Regulation No. 117 (ETRTO and Russia)
22 Jan 2014 Working Party Informal Documents Tire Rolling Sound Emissions, Adhesion on Wet Surfaces, and Rolling Resistance Tire Noise, Wet Adhesion, and Rolling Resistance Uniform provisions concerning the approval of tyres with regard to rolling sound emissions and/or to adhesion on wet surfaces and/or to rolling resistance Regulation 117, Annex 6 specifies several time duration values while Annex 6, Appendix 1 gives only one control accuracy value for time in its paragraph 4 (d): plus or minus 0.02 second. This means that this accuracy value applies to all the time durations specified in Regulation 117, Annex 6 and quoted above. This is not realistic for durations of more than one minute and not well fitted to the need of data acquisition for deceleration method. Therefore, Russia and ETRTO propose to introduce two accuracy sets of values in paragraphs 4 and 5 of Regulation 117, Annex 6, Appendix 1:<ol><li>a control accuracy of +/- 0.2 % s and a corresponding instrumentation accuracy of +/- 0.1 % s for the time increments specified in Annex 6 paragraph 3.5.a for the data acquisition in the deceleration method, both in ∆ω/∆t or dω/dt form, and</li><li>a control accuracy of +/- 5% and an instrumentation accuracy of maximum +/-10 sec for the other time durations specified in Annex 6.</li></ul> GRB-59-0003
