Proposed corrections and clarifications to the draft text of the new regulation to separate ESC provisions from Regulation No. 13-H (document GRRF/2014/12).

Proposal to clarify the intent of the selected paragraphs to ensure that systems with with one service brake meet braking performance requirements using only that brake system (i.e, without any assistance from the secondary brake system). There had been an interpretation that for systems with two service brakes each brake had to meet the requirements which would result in higher stringency levels than intended by the requirement for single brake systems.

The proposal also clarifies the parts of the braking system that should be considered with respect to hydraulic brake and mechanical transmissions and further clarifies that the test procedures are designed to simulate a brake failure rather than produce one.

Agenda updated by the GRRF secretariat with the latest informal document additions.

Presentation on definitions, applications, and regulatory options for the type approval of L-category vehicle all-terrain tires.

Amendments to the draft new regulation for the approval to tires installed on a vehicle in order to avoid overlap with UN R64 on spare tires.

Explanation of three options developed for handling the approval of electronic stability controls (ESC) and brake-assist systems (BAS) under regulaitons separate from UN R13-H (light vehicle braking) while fulfilling the requirements of complex electronic systems (CEL).

Editorial corrections by the ETRTO to its proposal to insert a new marking provision and under “categories of use”, a definition for construction application (industrial tractor) tyres into UN R106.

Proposal to clarify that like original brake discs and drums, original brake lining assemblies & drum brake linings are also not subject to this regulation and to refine the definition of “m_axle” as the “maximum technically” permitted mass of the axle in alignment with the definition in Annex 11-Appendix 1, Table 1 of UN R13.

Presentation by the head of the EU-funded COMPANION project to test and validate heavy-duty vehicle-to-vehicle platooning technologies. The program is aimed at gathering real-world experience with heavy vehicles formation of and interaction with connected vehicle platoons.

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 to clarify provisions on the use of Combined Braking Systems (CBS) and make some additional editorial improvements. This document contains GRRF/2014/05, GRRF/2014/06, GRRF-76-36 Rev 1 and updated by the comments raised at the seventy-sixth GRRF session.
