UN R90 unintentionally omits the bedding procedure for the brake drum high load test for M2, M3, N2 and N3 vehicles. CLEPA proposes using the same bedding procedure as already adopted for the thermal fatigue test for such vehicles and for the high load tests for trailers.

Draft agenda for the sixth session of the informal group on Automated Connections between Vehicles.

The use of test reports in Regulation No.13 was first introduced in Annex 11 of UN R13 in 1984. CLEPA proposes this amendment to support the proposal to permit the use of an Annex 19 test report as an alternative method in meeting the vehicle stability function requirements as detailed in Annex 21.

Denmark submitted document GRRF-71-19 (subsequently integrated into GRRF/2012/12) proposing to narrow the compatibility bands for control line pressure versus brake rate. This document challenges the proposed changes as effectively mandating electronic braking and imposing unwarranted costs.

Denmark submitted Document GRRF-71-18 (subsequently integrated into GRRF/2012/12) proposing to narrow the limits for coupling force control systems which are allowed to override the compatibility bands. This document argues against the proposed changes.

Denmark submitted GRRF-71-19 (subsequently in GRRF/2012/12) proposing a new paragraph to require a test point between the coupling head and the trailer relay emergency valve. This document argues that the requirement is already implicit within UN R13 and therefore, that the change is unnecessary.

This document addresses the ramifications of introducing the proposals outlined in GRRF-72-07 (superceded by GRRF-72-07/Rev.1) specifically associated with semi-trailers.

The extension of UN R90 to include brake drums and discs introduced the concept of a part “identical” to the OE part. Because such parts would have been approved under UN R13/13-H, they were exempted from redundant approval under R90. This proposal would similarly define and exempt brake linings.
