UN R9: Proposal for the 08 series of amendments
Document GRB-68-22
13 September 2018

Proposal to align ASEP for high powered L4 and L5 vehicles, used for passenger transport, is proposed in line with UN Regulation No 41.04 due to comparable sound emissions levels of L4 and L5 vehicles with the ones of L3 vehicles and the possibility of applying similar measurement methods for sound emissions for those vehicle categories. This is also supported by the Commission study on enhanced sound requirements for mopeds, quads and replacement silencers of L-category vehicles which resulted in amendments to UN Regulation Nos 9, 63 and 92 (ref. document WP.29/2017/2).

4. The expert from IMMA proposed to correct an inconsistency in the exemption conditions applicable to the additional sound emission provisions (ASEP) for vehicles with variable gear ratios or automatic transmission with non-lockable gear ratios (GRB-69-14 and GRB-69-16). The expert from Germany made a study reservation. GRB invited IMMA to convert the proposal into an official document for consideration at the next session.

3. The expert from the European Commission proposed to introduce additional sound emission provisions (ASEP) for L4 and L5 category vehicles with the power-to-mass ratio (PMR) of more than 50 W/kg (ECE/TRANS/WP.29/GRB/2018/7 and GRB-68-22). GRB adopted the proposals, as amended (Annex II), and requested the secretariat to submit them to WP.29 and to the Administrative Committee (AC.1) for consideration and vote at their March 2019 sessions as draft 08 series of amendments to UN Regulation No. 9.

34. The expert from EC proposed amendments to Regulation No. 9 with the aim to introduce ASEP requirements for L4 and L5 category vehicles with the power-to-mass ratio (PMR) of more than 50 W/kg (GRB-66-10). The Chair and the expert from Poland raised questions on referencing Global Technical Regulations (GTR) No. 15. The Chair also pointed out that the proposals should be accompanied with transitional provisions and invited the expert form EC to submit updated proposals to the next GRB session as an official document.
