Proposal to introduce new requirements for trailers braked by an inertia (overrun) braking system.

Text prepared by Germany to clarify that an electromechanical transmission device is allowed in addition to an electrical or a hydraulic transmission device within electrical braking systems.

Knott TrailerTechnik proposal to update the wording of Annex 14, para. 1.1 to cover “electromechanical or electrohydraulical” brake transmission devices. Primarily in German language.

This document seeks to correct a “copy and paste” mistake concerning a signature requirement made when copying text from Annex 11 into Annex 12, Appendix 4. This proposal would delete the superfluous passages.

Text prepared by Germany to clarify electrical braking system and energy supply line requirements with regard to towed trailers, including proposals for voltage specifications and inclusion of electro-hydraulic transmission devices within such systems. The text also seeks to align terminology with comparable paragraphs in other UN Regulations.

Proposal to require an automatic adjustment of the service brakes for trailers of class O1 and O2.

Supporting document to explain Germany’s proposal for mandatory automatic adjustment of brakes for class 01 and 02 trailers.

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 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 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 simplify the verification of sufficient movement on the balancer (of the compensator) without having to take measurements underneath the trailer in an potentially unsecured position and to correct the text of Annex 12 (Conditions governing the testing of vehicles equipped with inertia (overrun) braking systems). Intention to provide an objective calculation method as part of setting requirements for permissible “differential travel” or swivel.

Proposal to simplify the verification of the sufficient movement on the balancer without having to take measurements underneath the trailer in a potentially unsafe position.

Proposal to clarify the intent and rationale behind the proposal to simplify the verification of sufficient movement on the balancer without having to take measurements underneath the trailer in a potentially unsafe position.

Proposal to introduce requirements for endurance braking systems for vehicles equipped with an electric regenerative endurance braking system. This proposal is an alternative to the text proposed in document GRVA/2020/37.

Proposal to require electrically operated parking brake systems to automatically activate when the driver leaves the vehicle cabin and/or the motor is stopped.

Proposal to establish requirements for automatic activation of the parking brake to address safety of drivers leaving the occupant cabin.

Proposal to clarify provisions concerning the type-IIA test and the test mass of vehicles authorized to tow trailer(s).

Proposal to clarify provisions concerning the type-IIA test and the test mass of vehicles authorized to tow trailer(s).

Proposal to ensure that endurance braking is assessed in the context of the Type II-A test based on the maximum mass of the vehicle or vehicle combination.
