Proposal that would correct and clarify provisions within Annex 10 that apply not only to category O2 and O3 trailers, but also, as intended, to category O4 trailers.

Text prepared by the Netherlands to suggest improvements and simplifications of the transitional provisions in UN Regulations 13 and 13H.

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.

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 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”.

Proposal for corrections to the text and equations.

Proposal to delete a redundant requirement. The paragraphs 2.2. and 2.2.1. are superfluous since paragraph 5.2.2.13. already requires all O4 trailers to be equipped with Anti-lock Braking Systems (ABS) of Category A.

Proposal to clarify the need to apply, when relevant, the Type IIA test in Annex 15 for alternative brake lining purposes (e.g., in the case of vehicles with regenerative braking for Type IIA endurance test purposes to use the friction brake as an alternative to the regular endurance brake).

Proposal to clarify the need to apply, when relevant, the Type II test as required by Annex 4 paragraph 1.8.2.5 (b) in Annex 15 for alternative brake lining purposes.

Proposal to clarify the need to apply, when relevant, the Type II test as required by Annex 4 under paragraph 1.8.2.5 (b) in Annex 15 for alternative brake lining purposes.
