Working Party on Noise | Session 68 | 12-14 Sep 2018
Geneva

The deadline for the submission of official working documents is 18 June 2018.

This session will address a major change in GRB responsibilities pursuant to the WP.29 decision to establish a Working Party on Automated Vehicles (GRVA) by a “conversion” of GRRF. As a result, WP.29 anticipates transforming GRB into GRBP (Groupe de Rapporteurs pour le Bruit et les Pneumatiques") with responsibility for tyre regulations. Please see agenda item 14 for further information.

Agenda Item 4. (b)
UN R51: Additional sound emission provisions

7. On behalf of IWG ASEP, the expert from Germany presented their status report to GRB (GRB-68-20) and updated Terms of Reference (ToR) (GRB-68-21). GRB adopted the revised Terms of Reference, as laid down in Annex III, and requested the Chair of GRB to invite WP.29, at its November 2018 session, to extend the mandate of IWG ASEP until September 2020.

8. The expert from IWG ASEP presented GRB-68-03 on interpreting the general ASEP provisions in the last sentence of paragraph 6.2.3. of the 03 series of amendments to UN Regulation No. 51. IWG ASEP was of the view that the developed definitions and specifications were adequate and valid enough to satisfy the intention of this sentence. Outside the specified control range, IWG ASEP deemed it difficult to provide viable specifications. IWG ASEP suggested that the provided interpretation be used as guidance for manufacturers, technical services, and type approval authorities for the practical application during type approval, conformity of production, and market surveillance.

9. GRB endorsed GRB-68-03 and requested the secretariat to publish it as a reference document under a special folder on the GRB website. GRB also recommended IWG ASEP to keep this document for further consideration within the ongoing revision process of ASEP.
