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 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 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.

Revised proposal by Italy to introduce requirements for the approval of replacement brake discs for L-category (motorcycle and related) vehicles pursuant to comments received at the September 2014 GRRF session.

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 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.
