This proposal was prepared by OICA and is based on the existing UN Regulation No. 64. It is aimed at moving the Tyre Pressure Monitoring System provisions into a separate Regulation.

Status report, including the current state of the draft text, on efforts to reach agreement on the introduction of provisions for electro-hydraulic systems into the test conditions for trailers with electrical braking systems.

Presentation discussing the framework for relating independent regulations on electronic subsystems of braking or steering systems to the primary braking/steering regulations.

Supporting explanation for the proposal to align UN R79 with UN R13-H concerning cases where the braking and steering systems have the same energy source. This proposal would clarify and reaffirm that where there is “a failure in the energy supply, the steering system shall have priority”.

Amendments to document GRRF/2013/20 (proposal to include ATV tires in the motorcycle and moped tire regulation in order to enable the type approval of tires designed to equip quadricycles covered by the new Regulation (EU) No. 168/2013).

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.
