Under the International Whole Vehicle Type Approval (IWVTA) program, brake assist systems (BAS) and electronic stability controls (ESC) would be separated from UN R 13-H into new stand-alone regulations. This document has been prepared by an ad hoc group in order to ensure adequate transitional provisions to enable Contracting Parties to adapt to the new approach.

Proposal for a new annex concerning “special additional requirements for trailers of category O₂ without pneumatic connections and equipped with service braking systems with pneumatic energy storage devices”.

Proposal for a separate TPMS regulation, removing the Tyre Pressure Monitoring System provisions out of UN R64, in order to facilitate the establishment of the International Whole Vehicle Type Approval system. It is based on document GRRF/2015/13 taking into account the comments received at GRRF-78.

Draft proposal for a revised UN R64, removing the type-pressure monitoring systems provisions, in order to facilitate its use in the International Whole Vehicle System.

IMMA presentation regarding the intention to propose emergency stop signal (ESS) provisions to UN R78 and GTR No. 3. ESS, which automatically activates hazard warning lights during forceful braking situations, already exists under UN R13-H for cars and trucks. IMMA has submitted document GRE-2015-40 to similarly amend UN R53.

Proposal to introduce a new Annex 7: “Special provisions for the powering of trailer steering systems from the towing vehicle” and otherwise amend the regulation to enable the approval of such trailer steering systems which the current text prohibits.

Text as approved by the GRRF and prepared by the UN R55 informal group 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.

Proposal is to align GTR 16 with technical progress, incorporating new provisions for wet grip performance, rolling resistance and qualification for use at severe snow conditions both for passenger car (PC) and light truck / commercial (LT/C) tyres (as were recently adopted within UN Regulation No. 117). The proposal also includes updates from relevant FMVSS and UN Regulations Nos. 30 and 54.

Explanatory report on the development and contents of the amendment concerning wet grip, rolling resistance, and other updated provisions for GTR 16 on tyres.

Proposal for a revised UN R64 that removes the provisions for tyre-pressure monitoring systems (TPMS) (to be reproduced in a new separate regulation) in order to facilitate the application of UN R64 within the International Whole Vehicle Type Approval system.

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

Proposed new stand-alone UN Regulation comprised of the brake assist systems provisions of UN Regulation 13-H.

Proposal for a new stand-alone UN Regulation on electronic stability control systems comprising the ESC provisions removed from UN R13-H.

Proposed text for a new regulation on tire installation for use within the International Whole Vehicle Type Approval system.

Proposal for revised transitional provisions under the regulation.
