Proposal for Supplement 4 to the 02 series of amendments to Regulation No. 117

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.
