Proposal to delete references to tire-pressure monitoring systems under UN R64 (with the intention to establish them as a stand-alone regulation). This document presents only the amendments and complements the earlier document GRRF-78-38 that presented the consolidated version of UN R64 amended as proposed here.

CLEPA proposed a framework for relating independent regulations on electronic subsystems of braking or steering systems to the primary braking/steering regulations. This proposal revises the wording, focusing on ESC systems with relation to the requirements for complex electronic control systems under Regulation 13-H.

For testing purposes, UN R90 defines a “test group” as a grouping of parts having the same characteristics. The regulation then defines a “variant” as a part within a “test group”. However, the approval numbers under the rule stipulate the identification of each variant certified. As a result, the text technically requires certification of each individual part (variant) which was not the intention of the drafters. CLEPA raises this for information purposes with the intention to put forward a proposal at the next GRRF session.

IMMA comments on the suggestion to include a cross reference to UN R10 in UN R78 in order to ensure that electromagnetic interference does not affect electronic brake modules in a way that causes unsafe brake operation as was adopted for UN R13.

Correction to document GRRF/2015/8 (Proposal to remove certain design restrictions that impede the application of new technologies, especially related to trailer power steering systems and the use of energy from the towing vehicle), updating a reference to a paragraph number that has changed.

Agenda for the special GRRF session planned during the week of the June 2014 World Forum session and organized to resolve the remaining open issues of the draft global technical regulation on tyres.

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

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

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.

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.

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

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.

Annotations to the provisional agenda (document GRRF/2015/1).

Text prepared by the experts from the LKAS small drafting group to introduce new definitions and the related LKAS requirements in to the text of UN Regulation No. 79.

European countries are considering new requirements to require the fitment of snow tyres for use in severe snow conditions on specific axles of heavy duty vehicles. New tyres are approved under UN R117; however, a large percentage of heavy duty vehicles are fitted with retreaded tyres which are outside the scope of UN R117. This proposal would transpose the relevant requirements for new snow tyres into UN R109 in order of avoid the exclusion of retreaded tyres from such applications/markets.

Revised proposal to introduce general performance guidelines into the annex on automated driver assistance systems in order to set initial safety considerations to guide the commercialization of this emerging technology. Specifically addresses remote-controlled parking systems (RCP).

Proposal from the European Tyre and Rim Technical Organisation (ETRTO) in order to add new tyres for light commercial vehicles (high flotation tyres) in Annex 5 of UN Regulation No. 54.

Proposal to permit the “LT” marking as a prefix or suffix to align the requirements with the current practice for C2 tyres with metric size designation. The proposed text for a prefix is in line with the latest draft of the gtr on tyres. The proposed text for a suffix is necessary for tyres designed to Japan Automobile Tyre Manufacturers Association (JATMA) standards.

Proposal to add a maximum supply line pressure of 900kPa when the compressor is at cut-out during testing of electronic braking systems (EBS). The aim is to prevent trailer EBS failure warnings/shut downs when detecting excessive supply line pressure.

Proposal to remove certain design restrictions that impede the application of new technologies, especially related to trailer power steering systems and the use of energy from the towing vehicle.

Proposal to restore transitional provisions incorrectly deleted by Supplement 6 to the 02 series of amendments.

Proposal to clarify the definition of a “variant” in order to avoid unintended interpretations of the certification requirements that could result in additional financial and administrative costs. As currently worded the approval of a Test Group requires individual certification for each part contained within the Test Group. Some Test Groups can contain in the region of 30 part numbers. This would align the practice for brake discs and drums with that for brake linings.

Pursuant to the addition of a new speed symbol for forestry tyres, this proposal would add a bonus loads column for A6-rated tyres to Annex 7-Part D.

Proposal to separate provisions for tire-pressure monitoring systems from UN R64.

Proposed text for a new UN Regulation that would comprise all the tyre-pressure monitoring system (TPMS) provisions presently contained in UN Regulation No. 64. This separation is proposed to facilitate the use of UN R64 in the international whole vehicle type approval system under development.

Proposal draft by the informal group on UN Regulation No. 55 to update this regulation with respect to:
a) Requirements on remote indication;
b) Availability of information on coupling fixing points for A50X couplings;
c) On lateral strength of drawbars; and
d) a new class definition for fully automatic drawbar couplings.

Corrections to the tables concerning “Agricultural implement tyres – Normal section sizes”.

Deletion of a paragraph (concerning UN R90) inadvertently inserted into the justification for the this proposal.
