Working Party Informal 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>
