Annotations to the provisional agenda for the February 2014 GRRF session.

Proposal by the European Tyre and Rim Technical Organisation (ETRTO) to insert a new marking provision and, under “categories of use”, a definition for construction application (Industrial tractor) tyres into UN R106.

Updated proposal 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” and the use of a representative vehicle based on UN R13-H.

Proposal from Italy to clarify provisions concerning the use of Combined Braking Systems (CBS) in GTR No. 3.

Proposal from the International Motorcycles Manufacturer Association (IMMA) to introduce amendments clarifying the current text on the use of Combined Braking Systems (CBS) into UN R78.

Updated proposal for a series of amendments to clarify a variety of requirements, notably concerning test surface requirements, ABS cycling, and peak braking coefficient measurements under UN R78.

Proposal of the ad hoc expert group on transitional provisions to clarify and update these terms within the heavy braking regulation, including provisions for extensions of type approvals granted according to the antecedent requirements of the original approval. These amendments also relate to the transfer of brake-related telltale provisions to UN R121.

Proposal to enable the approval of positive steering of trailers using energy supply and electrical control from the towing vehicle because standards applicable to energy supply connectors and digital information interchange have not been established.

Proposal to improve the definition of “identical” parts as applied to replacement brake discs and drums and to introduce an “identical” part definition for brake linings. This documents supersedes document GRRF-75-18.

Proposal for amendments to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations.

Proposal to transfer brake assist system systems provisions out of UN Regulation 13-H and into a new stand-alone regulation. The proposal arises from a perceived need to simplify UN R13-H to facilitate its application within the proposed international whole vehicle type approval. This document supersedes document GRRF-75-14.

Proposal to transfer electronic stability control systems provisions out of UN Regulation 13-H and into a new stand-alone regulation. The proposal arises from a perceived need to simplify UN R13-H to facilitate its application within the proposed international whole vehicle type approval. This document supersedes document GRRF-75-15.

Proposal for a new regulation for the approval to tires installed on a vehicle. This regulations is proposed for use within the International Whole Vehicle Type Approval system in order to ensure proper tire fitment on a vehicle under IWVTA evaluation. This document supersedes GRRF-75-20.

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.
