Presentation on the tire industry position concerning the implementation of new minimum requirements for wet grip on C2 and C3 tyres

Proposal submitted by ETRTO and prepared with the Netherlands, UK, and Poland to amend UNECE Regulation 117 in order to allow the use of test tracks complying to ISO 10844:2011, including transitional provisions.

Updated GRB revisions to the proposal for Supplement 2 to the 02 series of amendments to Regulation No. 117 adopted by the Working Party on Brakes and Running Gear (GRRF) at its seventy-second session in order to add specific performance requirements for C2 snow tires.

Document WP.29/2012/54 is the GRRF proposal for Supplement 2 to the 02 series of amendments to Regulation No. 117 in order to add specific performance requirements for C2 snow tires. The GRB has subsequently revised the proposal with regard to its noise provisions.

Table showing the status of the revisions to selected UN Regulations, including the new UN R127 (LED lighting) and R128 (Pedestrian safety). Revisions consolidate and update regulations as a single text.

(Duplicate version of the previous WP.29-158-09 removing some tracking marks.)
GRRF-edited version of the GRB amendments to document WP.29/2012/54 – Proposal for Supplement 2 to the 02 series of amendments to Regulation No. 117 (Tyres – Rolling resistance, rolling noise and wet grip).

Proposal to update noise test-track requirements from ISO 19844:1994 to ISO 10844:2011 and incorporates transitional provisions to allow repaving of existing, non-compliant test tracks with the ISO 10844:2011 standards. This supersedes document GRB/2012/9.

Proposal by the Chair and Vice-Chair of GRB to allow the use of the test track complying with ISO 10844:2011 in a new series of amendments to the UN R117. This is based upon document GRB-56-20 from the previous GRB session.

Proposal from the Russian Federation to elaborate on the concept of tyre deceleration (dω/dt) in the test technology. The proposal is based on informal document GRB-56-02 from the previous GRB session.

Proposed revisions to the Annex 3 test procedures and interpretation of resulting data. This is based upon informal document GRB-56-06.

Text prepared by the European Commission (EC), France and European Tyre and Rim Technical Organisation (ETRTO) in order 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 73rd session to align the definition of the temperature correction coefficient “K” in UN R117:02 series of amendments with ISO 28580.

Text adopted by the Working Party on Noise (GRB) at its fifty-sixth session as a consolidated version of the Regulation and aligning the test methods with those introduced into Regulation No. 41.

Text adopted by the Working Party on Noise (GRB) at its fifty-sixth session as a consolidated version of the Regulation and aligning the test methods with those introduced into Regulation No. 41.

Text adopted by the Working Party on Noise (GRB) at its fifty-sixth session to revise the figure for the measuring positions of the vehicles in motion.

Corrections to the proposal from the Russian Federation to elaborate on the concept of tyre deceleration (dω/dt) in the test technology.

Response to the proposal to update references to the permissible test tracks (document GRB/2013/2), arguing that the change from ISO 10844:1994 to ISO 10844:2011 is unnecessary since it does not change the test method to measure the tyre rolling noise.
