AMEVSC secretary’s final version of the proposed amendments to Appendices 2 of Annex 21 to clarify the use of test reports for the validation of the simulation tool in order to avoid making test reports issued prior to entry into force of Supplement ¹⁰ to Series 11 of UN R13 invalid.

Proposed amendments to Appendix 2 of Annex 21 to clarify the use of test reports for the validation of the simulation tool in order to avoid making test reports issued prior to entry into force of Supplement ¹⁰ to Series 11 of ECE R13 invalid.

Amendment prepared by the Informal Working Group on Automated Connections between Vehicles to enable the use of automatic coupling systems.

Presentation to accompany Danish, et. al. proposal on heavy-duty vehicle and trailer brake system compatibility.

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.

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.

This document addresses the ramifications of introducing the proposals outlined in GRRF-72-07 (superceded by GRRF-72-07/Rev.1) specifically associated with semi-trailers.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

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

This proposal aims to improve brake distribution between truck and trailer of heavy vehicle combinations at everyday low decelerations, to enhance uniform use of all wheel brakes and thereby to counteract loss of full brake performance. The proposal is based on ISO 20918 and supercedes GRRF-72-07.
