Proposals by Germany and the Netherlands to clarify trailer requirements under UN Regulation Nos. 13 and 13-H, including the removal of design restrictions that prevent the use of electro-hydraulic and electro-pneumatic braking systems.

Proposal from Germany to introduce a new Annex 23 into UN Regulation No. 13 covering special additional requirements for trailers of category O2 without pneumatic connections and equipped with service braking systems with pneumatic energy storage devices. In addition, the document proposes to further amend braking requirements for trailers under Regulation No. 13 and 13-H to address these new braking systems.

Proposal for collective amendments of amendments to Regulations Nos. 13 (Heavy vehicle braking), 13-H (Brakes of M1 and N1 vehicles), 79 (Steering equipment) and 89 (Speed limitation devices) and the new Regulations on LDWS and AEBS to clarify the references to Regulation No. 10 into the UN Regulations mentioned above.

Proposal to correct errors and remove inconsistencies in the current regulatory text, including a correction to the formula used in Annex 12, Appendix 4 “Test report on the compatibility of the inertia brake control device, the transmission and the brakes on the trailer”.

This supplement would introduce provisions for fully automatic coupling systems and clarify references in the regulation to Regulation No. 10 on electromagnetic compatibility. This proposal combines two distinct proposals (document GRRF/2013/12 as amended by Annex II to the GRRF 75th session report and document GRRF/2013/13 not amended) approved by the GRRF at its September 2013 session.

Proposal for a new annex concerning “special additional requirements for trailers of category O₂ without pneumatic connections and equipped with service braking systems with pneumatic energy storage devices”.

Proposal to add a trigger threshold requirement and to modify the sampling rate, deceleration limit and data selection criteria for category B brake-assist systems.
