Based upon a proposal from the ETRTO and the UK, this text was adopted by the Working Party on Noise (GRB) at its 57th session to update noise test-track requirements from ISO 19844:1994 to ISO 10844:2011 and incorporate transitional provisions to allow repaving of existing, non-compliant test tracks with the ISO 10844:2011 standards.

Project timeline envisioning submission of final recommendations to the GRB in September 2014 followed by adoption of the new minimum-noise GTR by WP.29 in March 2015.

Text as adopted by the Working Party on Brakes and Running Gear (GRRF) at its 75th session based upon a proposal by the European Commission, France and ETRTO to introduce wet grip provisions and testing procedures for tyres of categories C2 and C3.

Text as adopted by the Working Party on Brakes and Running Gear (GRRF) at its 74th session based upon a European Tyre and Rim Technical Organisation (ETRTO) proposal to amend the snow test method for C3 tyres in order to prescribe the wider of the possible speed ranges (document GRRF/2012/19). Please note that this proposal was adopted at the November 2013 (161st) WP.29 session as Supplement 5, having originally been proposed as Supplement 4 during the June session.

Clarification submitted by the GRB chair of the transition provisions in the proposal to update noise test-track requirements from ISO 19844:1994 to ISO 10844:2011 and incorporate transitional provisions to allow repaving of existing, non-compliant test tracks with the ISO 10844:2011 standards.
