GRRF-83-22 | Proposal for amendments to Regulation No. 13-H Supplement 16 to 00 series of amendments, Regulation No. 13 Supplement 14 to 11 series of amendments and Regulation No. 140 original version Proposal to amend provisions on electronic stability control warnings under braking regulations to allow for activation of the ESC visual warning during a stability-assistance intervention of an electronic steering control. The aim is to avoid separate requirements for brake-actuated and steering-actuated stability assistance that would lead to two visual warnings where only one is appropriate.

GRRF-83-22/Rev.1 | Revised proposal for amendments to Regulation No. 13-H Supplement 16 to 00 series of amendments, Regulation No. 13 Supplement 14 to 11 series of amendments and Regulation No. 140 original version Revised proposal pursuant to GRRF discussions to enable activation of the ESC optical symbol in cases of a corrective steering function intervention when the CSF intervention is activated under the control of an ESC system. The aim is to avoid separate requirements for brake-actuated and steering-actuated vehicle stability functions (VSF) that would lead to two optical warnings where only one is appropriate.

GRRF-83-07 | Proposal for amendments to Regulation No. 13, Annex 12 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.

GRRF/2013/13 | Proposal for collective amendments - Regulation Nos. 13, 13-H, 79, 89, and the LDWS and AEBS regulations 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.

WP.29-168-16 | Proposal from WP.15 to amend Regulation No. 13 Proposal from the Working Party on Dangerous Goods to delete paragraph 2.2.1 and 2.3.2 in Annex 5 of Regulation No. 13 permitting the use of an endurance braking system on a trailer to compensate for insufficient performance of the endurance braking system of the motor vehicles. Such systems have been prohibited by WP.15 such that alignment of the vehicle technical requirements is needed.

GRRF/2016/27 | Proposal for amendments to Regulation No. 13 UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls. This proposal seeks to clarify the scope of the exemptions to include any special purpose vehicle with a non-standard chassis. The change was prompted by a modified vehicle where use of ESC was not feasible, but where the current UN R13 language left doubt as to whether the ESC requirement was applicable. This revised proposal takes into account comments received during the February 2016 GRRF session.

GRRF-82-03 | Proposal for amendments to Regulations No. 13 UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls. This proposal seeks to clarify the scope of the exemptions to include any special purpose vehicle with a non-standard chassis.

This revised proposal takes into account comments received during the February 2016 GRRF session.

GRRF/2016/26 | Proposal for amendments to Regulation No. 13 Proposal to clarify paragraph 8.1.2. The paragraph aimed to verify that the compensator can accept a difference of the travel when one brake operates in forward direction and the other in rearward direction with a margin of twenty per cent.

GRRF/2017/2 | Proposal for an amendment of Regulation No. 13 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.

GRRF-83-07 | Proposal for amendments to Regulation No. 13, Annex 12 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.

GRRF-83-31 | Proposal for amendments to Footnote 12 in Regulation No. 13 UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls (footnote 12). This proposal (following proposals GRRF/2016/27 and GRRF-82-03) seeks to clarify the scope of the exemptions to include any special purpose vehicle with a non-standard chassis. The change was prompted by a modified vehicle where use of ESC was not feasible, but where the current UN R13 language left doubt as to whether the ESC requirement was applicable.

GRRF-83-09 | Proposal for Amend. [3] to GTR No. 3 Proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78.

GRRF-83-10 | Proposal for amendments to GRRF-83-09 on amending GTR No. 3 Proposal to delete passages under paragraph 3.1.15.2. referring to the “prediction of the vehicle deceleration” since no method for doing so is described in the regulation. Moreover, in a self-certification system, the requirement would have to be met for the actual vehicle deceleration. The proposal also substitutes switching between ABS modes for the terms "disable" and "deactivate" for greater clarity. Lastly, the proposal recommends the use of a clearly specified telltale design to signal the ABS operating status rather than to leave this function open to “…any other equivalent unequivocal indication of the disabled antilock brake system state.”
