This document is based on document GRB/2012/8 including documents GRB-57-17 (OICA amendments to the transitional provisions), GRB-2013-05 (modified ETRTO amendments for the use of the ISO 10844:2011 test track specifications), and the latest decisions of the EU Council.

Proposal from the International Organization of Vehicle Manufacturers to update the requirements on the noise test track to the latest stage of the applicable standards (from ISO 19844:1994 (i.e. Annex 8 of this Regulation) to ISO 10844:2011) and to incorporate transitional provisions to allow repaving of non-compliant test tracks to the ISO 10844:2011 standards.

Proposal to amend the classifications of vehicle type in the consolidated version of the proposal for draft 03 series of amendments to Regulation No. 51.

There are two types of N1 having GVM<2.5t. One is front engine type. The other is a flat front vehicle with the engine under the seat and typical in Asian countries. Japan proposes that the sound limit of the latter type should be considered since the sound characteristics of the vehicles are same as that of the N1 having GVM<2.5t.

Discussion paper concerning acceleration test border lines.

China comments on Japanese proposal concerning vehicle categories and noise-limit values.

Discussion paper towards defining vehicle subcategories capable of addressing range of vehicles found in Chinese market, including high‐performance coupes, sports cars, saloon cars, SUV, MPV, Kei‐cars, Kei‐trucks, mini‐buses, mini‐trucks and so on.

Presentation in support of document GRB-58-06 proposing amendments to UN R51 with regard to the categorization of flat-front light (kei) commercial vehicles.

Japan opposes the inclusion of specifications for Acoustic Vehicle Alerting Systems (AVAS) as contained within the consolidated proposal for the 03 series of amendments to UN R51 (GRB-58-04). AVAS specifications are actively under development as a new GTR and therefore, Japan cannot accept their definition under UN R51 until the GTR deliberations have been concluded.
