Changes agreed upon during the speciall GRRF session to finalize the draft global technical regulation on tires, especially in response to the amendments proposed by the United States (document GRRF-77-01).

Proposal based on informal document GRRF-76-21 to remove all references to Annex 10 from Annex 13 by transferring the provisions concerning vehicles with and without anti-lock braking systems to Annex 10.

Text prepared by the informal group of experts on Regulation No. 55 to introduce amendments on requirements for movable couplings, increased range of application of remote controls to couplings similar to C50-X and G50-X, possible increase of characteristic values of standard couplings and to include of further requirements on the mounting of couplings.

Proposal based upon informal document GRRF-76-45 to clarify provisions on the use of Combined Braking Systems (CBS) and make some additional editorial improvements.

Proposal to clarify provisions concerning the use of Combined Braking Systems (CBS) and for a series of amendments to clarify a variety of requirements, notably concerning test surface requirements, ABS cycling, and peak braking coefficient measurements. The proposal clarifies the terms “inoperative” and “disconnected”, introduces the “K-method”.

Proposal by Italy to introduce requirements for the approval of replacement brake discs for L-category (motorcycle and related) vehicles.

Proposal for amendments as adopted during the 77th GRRF session specially devoted to the finalization of the draft GTR text.

Proposed changes from the ETRTO to clarify the communication form in Annex 1.

Proposal to alter the marking requirements after November 2016 to replace the PSI Index by indicating the inflation pressure in kilopascals (“kPa”) and to add the possibility to put the “LT” marking as a prefix or suffix to align the requirements with current practice for C2 tyres with metric size designation

IMMA counter-proposal to the ETRTO proposal to amend Regulation No. 75 with regard to ATV tyres and replaces documents GRRF/2013/22 and GRRF/2013/20 taking into consideration the comments made at the last GRRF session in February 2014.

Proposal to clarify braking requirements and to align them with UN R13-H on light vehicle braking.

Proposal to add classifications covering agricultural trailers and towed agricultural machinery in the Consolidated Resolution on the Construction of Vehicles (R.E.3).

List of terms defined in regulations under the purview of the Working Party on Brakes and Running Gear presented to facilitate discussions on the harmonization of such terms and definitions.

Proposal to introduce a definition and provisions for lane-keeping assist systems (LKAS).

Proposal to clarify the provision for permissible deactivation of ABS systems under the proposal to clarify the use of Combined Braking Systems (CBS) under UN R78.

Proposal to clarify the provision for permissible deactivation of ABS systems under the proposal to clarify the use of Combined Braking Systems (CBS) under GTR No. 3.

Supplementary agenda including references to all documents received prior to 9 September.

Change to the proposed text pursuant to agreement within the “LKAS Small Drafting Group” concerning the “means of detecting that the driver is likely to be no longer in primary control of the steering system” and related driver warning method(s).

Clarifications and corrections to document GRRF/2014/26 which proposes to alter the marking requirements of UN R54 to replace the PSI Index by the inflation pressure in kilopascals (“kPa”) and to add the possibility to put the “LT” marking as a prefix or suffix to align the requirements with current practice for C2 tyres with metric size designation.
