UN R13: Proposal for a Supplement to the 11 series of amendments
Reference Number: GRVA/2021/24
Introduces requirements for the type approval of Electro-Mechanical Braking (EMB) systems as state-of-the-art braking systems. This document supersedes ECE/TRANS/WP.29/GRVA/2020/21 and informal document GRVA-09-05.
UN R78: Proposal for a Supplement to the 05 series of amendments
Reference Number: GRVA/2021/26
Proposes to align UN Regulation No. 78 with the latest amendments to UN Regulation No. 13-H regarding the deceleration thresholds for the activation of the stop lamp(s) under regenerative braking
Proposal allows discs with a different geometry to be included in the same group as long as the disc itself is subject to lower thermal and mechanical stresses than the reference disc. Aims at simplifying the definition of disk groups, reducing their number, while providing the same guarantees from a technical point of view.
Clarifies the regulation and its scope, by specifying the grouping criteria of the brake lining assemblies. It provides clear instructions about grouping criteria for brake shoes to allow brake shoes manufacturers to proceed with the homologation
