| 8. (a) | Electronic Stability Control |
GRVA agreed to resume consideration of the proposal to amend UN Global Technical Regulation (UN GTR) No. 8, aimed at introducing the testing provisions to accommodate the latest innovations for steering systems. GRVA agreed to resume consideration of the two alternative amendment proposals to UN Regulation No. 13, tabled by the experts from France and from the Organisation Internationale des Constructeurs d’Automobiles (OICA), aimed at including all four axles with two power-driven rear axles in the scope of the mandatory installation of a vehicle stability function. |
WP.29/2020/99 | GTR 8: Request for authorization to develop an amendment
Request to develop an amendment to the GTR 8 testing provisions to accommodate the latest innovations for steering systems which have significantly low steering gear ratio (i.e. quick steering characteristics).
GRVA-13-23 | UN R13: Proposal to amend document GRVA/2022/14
GRVA-13-39 | UN R13: Proposal to amend document GRVA/2022/14
Proposal to ensure that N<sub>3</sub> category four-axle chassis, regardless of bodywork in second stage production (e.g., concrete mixer), will be included within the scope of the vehicle stability provisions.
GRVA-14-27 | UN R140: Proposal for amendments
Proposal for a provision to address use of a steering robot with mechanical power greater than 1200 W to enable testing of certain direct (low) steering gear ratio systems due to the given 0.7 Hz sine frequency.
GRVA-14-30 | UN R140: Supporting information on proposal for amendments
GRVA/2022/14 | UN R13: Proposal for amendments
Proposal to equip four-axle commercial vehicles over 25 tons with vehicle stability function due to their specific use.

| 8. (c) | Clarifications |
GRVA agreed to resume consideration of the amendment proposal to UN Regulation No. 140 prepared by the expert from OICA with the aim to ensure the continuity of the American Society for Testing and Materials (ASTM) Method E1337 for the measurement of the Peak Braking Coefficient (PBC) in UN Regulation No. 140, by introducing a reference to the new ASTM Standard Reference Test Tyre F2493.
GRVA-14-55/Rev.1 | UN R13-H: Proposal for amendments to the original version
Proposal to update the text with the American Society for Testing and Materials (ASTM) F2493-20 standard reference test tyre.
GRVA/2022/25 | UN R140: Proposal for amendment
Proposal to ensure the continuity of the American Society for Testing and Materials (ASTM) Method E1337 for the measurement of the Peak Braking Coefficient (PBC) in UN Regulation No. 140, by introducing a reference to the new ASTM Standard Reference Test Tyre F2493.
GRVA may wish to review amendments to UN Regulations No. 13, 13-H, 139 or 140, if available.
GRVA-14-32 | UN R13: Working draft for amendments
At the 13th session of GRVA the UK presented an informal document (GRVA-13-19) with the purpose of starting discussion on the content of UN Regulation 13, Annex 18. The proposal was made in recognition of the inconsistent understanding of the current text, identified during the discussions leading to the 03 series of amendments to UN R79 which shared common language. It is intended that using harmonised text between Regulations, as far as is practicable, will deliver more consistent application of the requirements and avoid unnecessary changes in procedures and documentation for different vehicle systems.
