GRB
Session 61 | Geneva | 27-29 Jan 2015
7. Regulation No. 117 (Tyre rolling noise and wet grip adhesion)
GRB/2014/8 | Proposal for Supplement 7 to the 02 series of amendments to Regulation No. 117 At the 58th GRB session, the expert from ETRTO introduced GRB-58-02, proposing new time measurement accuracy for instrumentation involved in the rolling resistance method (Annex 6 of the UN Regulation). The expert from the Russian Federation introduced GRB-58-13, arguing that this change of accuracy was not needed for Annex 6. This present revised proposal has been prepared the ETRTO and approved by Russia.
GRB-61-06 | Proposal for amendments to Regulation No. 117 Proposal from Japan, pursuant to the discussion of document GRB/2014/8 during the previous GRB session, to correct perceived inconsistencies in time measurement accuracy in annex 6.
GRB-61-09 | Method of deceleration measuring and data processing for tyre rolling resistance determination Pursuant to the introduction of the deceleration method for measuring tire rolling resistance using the dω/dt approach (“Deceleration Calculator”) proposed by NAMI and accepted by GRB, UTAC (France) provides information on the results of tests conducted to confirm repeatability and reproducibility of the new method using different machines.
GRB-61-14 | Proposal for amendments to Regulation No. 117 Proposal to update the test-track references to the recently published ISO 10844:2014.
GRRF/2015/9 | Proposal for a corrigendum of Supplement 6 to the 02 series of amendments to Regulation No. 117 Proposal to restore transitional provisions incorrectly deleted by Supplement 6 to the 02 series of amendments.
GRB-60-17 | ISO 10844: Comparison of 2014 version against 2011 version
9. Exchange of information on national and international requirements on noise levels
GRB-60-03 | Potential benefits of Triple-A tyres in the Netherlands "Quick scan" study prepared for the Dutch Ministry of Infrastructure and Environment to evaluate the potential of "triple A" tyres to improve vehicle safety, noise emssions, fuel consumption, and CO2 emissions. Tyres in the EU are labeled to convey information on their energy efficiency, safety, and noise performance. Triple A refers to tyres receiving the highest ratings across these three criteria.
GRB-60-08 | Tyre noise limits of EC/661/2009 and ECE R117: Evaluation based on sold tyres in the Netherlands Memorandum to the Netherlands Ministry of Infrastructure and the Environment in response to its request for research into<ul><li>the effect of the present tyre Regulations on the exterior noise levels of tyres</li><li>comparison of the tyre noise levels in the present distribution with the limit values defined in the tyre Regulations</li><li>definition of the levels of "present-day technology and ambitious technology on base of the distribution of levels found in the present tyre population".</li></ul>
GRB-60-08/Add.1 | Shifts in tyre sound levels between 2007 and 2013 (Addendum)
GRB-60-13 | Presentation on "quiet road surfaces" and their impact on rolling noise
GRB-60-14/Rev.1 | Triple-A tyres – benefits for environment, noise, safety and economy Tyres in the EU are labeled to convey information on their energy efficiency, safety, and noise performance. Triple A refers to tyres receiving the highest ratings across these three criteria. This presentation reviews data collected on the advantages demonstrated by such triple-A tyres.
