Text from the European Association of Automotive Suppliers (CLEPA) and from the International Organization of Motor Vehicle Manufacturers (OICA) to align the braking performance requirements for M1 vehicles in Annex 3 of UN R79 with those of UN R13-H (light vehicle braking).

Updated working paper (succeeding document GRRF-73-19) proposing to revise the transitional provisions of UN R13-H based on a review undertaken pursuant to the discussions at the last GRRF session.

Proposal to define the relief depth of tire markings and an editorial correction concerning the permissible tire marking fonts.

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.

Agenda for the GRRF Spetember session without annotations. The annotated agenda will be issued before the session as an addendum to this document.

CLEPA and OICA proposal to harmonize Regulations Nos. 13 and 13-H with the Federal Motor Vehicle Safety Standard FMVSS 135 on electric vehicle requirements with regard to the regenerative braking system (RBS).

Proposal to allow the use of test tracks constructed according to the new ISO 10844:2011.

Proposal to align the definition of the temperature correction coefficient “K” in UN Regulation No. 117: 02 series of amendments with ISO 28580. The issue is linked to tire categories: ISO refers only to load index while UN R117: 02 series refers to class C1, C2 and C3 tires.

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.

Proposal to correct the omission of the rim-diameter code 25 for the calculation of metric-designated tyres (this rim code appears in Annex 5, Table 7 for code designated tyres).

This document seeks to correct a “copy and paste” mistake concerning a signature requirement made when copying text from Annex 11 into Annex 12, Appendix 4. This proposal would delete the superfluous passages.

Proposed text and supporting report for the establishment of a global technical regulation on light vehicle tires, submitted to the Working Party on Brakes and Running Gear for approval by the Informal Group on the Tyre GTR.

Text prepared by Japan to clarify requirements on electromagnetic compatibility in Regulations Nos. 13 and 13-H via reference to Regulation No. 10.

Text prepared by the Federation of European Manufacturers of Friction Materials (FEMFM) proposing to exclude brake linings and/or lining assemblies that are chemically and physically identical to the original part from the requirements (as is currently the practice for brake discs and drums).

Proposal to align M1 vehicle braking performance requirements with UN R13-H provisions and clarify those for N1 vehicles in Annex 3 of UN R79.

Proposal to establish an expert group with a mandate to prepare new harmonized regulations for lane-keeping and parking-assist systems.

Text prepared by the International Motorcycle Manufacturers Association (IMMA) in order to introduce amendments to clarify the current text for the use of Combined Braking Systems (CBS).

Text prepared by the International Motorcycles Manufacturer Association (IMMA) clarifying the current text of the GTR regarding the use of combined braking systems (CBS).

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 prepared by the informal group on Alternative Method to assess the Electronic Vehicle Stability Control system (AMEVSC) clarifying the requirements in Annex 21 of UN Regulation No. 13 on the use of simulation, specifically in the Appendices 1, 2 and 3 of Annex 21.
