Text prepared by the European Tyre and Rim Technical Organisation (ETRTO) in order to correct inconsistencies in time measurement accuracy in annex 6.

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.

Consolidated proposal for the 03 series of amendments to UN Regulation No. 51, prepared by the expert group on UN R51 pursuant to their fourth meeting on 4 July.

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 pursuant to GRB discussions (55th session, para. 12) and document GRB/2013/8 to insert the amendments concerning the ASEP provisions as soon as Regulation No. 51 has been accordingly amended (in line with the draft proposal (Reference 2011/XXXX (COD)) of the European Commission “Proposal of the European Parliament and of the Council on the sound level of motor vehicles and of their exhaust systems”).

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.

Further background as requested at the last GRB meeting on the recommended use of a “deceleration calculator” software for the deceleration test method in the test procedure for measuring rolling resistance.

Proposal to revise the European Tyre and Rim Technical Organisation (ETRTO) proposals (documents GRB-58-02 and GRRF/2013/30) to correct inconsistencies in time measurement accuracy in annex 6 of the regulation.

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.

Proposal to include provisions on maximum noise emissions from audible vehicle alerting systems (AVAS) under development for low-sound vehicles.

Amendments agreed to document GRB-58-04 during the 58th session of GRB.
