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.

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”.

Correction to document GRRF/2015/8 (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), updating a reference to a paragraph number that has changed.

Deletion of a paragraph (concerning UN R90) inadvertently inserted into the justification for the this proposal.
