GRB
Session 62 | Geneva | 1-3 Sep 2015
3. Regulation No. 41 (Noise emissions of motorcycles): Development
GRB/2015/8 | Proposal for Supplement 4 to the 04 series of amendments to Regulation No. 41 In response to concerns that approval agencies may not grant manufacturers the additional 1dB for L(wot) on conformity of production tests as changes had been made to Annex 6 of R41-04, GRB issued an interpretation recorded in the report of its 56th session. The proposal formalizes the interpretation as an explicit provision of the regulation.
GRB-62-05 | Proposal to correct Supplement 2 to the 04 series of amendments to Regulation No. 41 Correction of two minor reference errors contained in the proposal for Supplement 2 to the 04 series of amendments to Regulation No. 41 which was adopted during the March 2015 session of WP.29.
GRB-62-15 | Proposal for a supplement to UN Regulation No. 41 The current text of UN R41 provides an allowance that increases the noise limit value by 1 dB(A) for motorcycles tested only in second gear under Annex 3. This allowance expires on 1 January 2017. IMMA proposes to extend this allowance until 1 January 2018 in response to the delayed implementation of UN R41-04 in the EU (2016 instead of planned 2014).
8. Collective amendments
GRB-62-06/Rev.1 | Proposals to clarify provisions in Regulations Nos. 9, 41, 63 and 92 Proposal to specify that conditioning of exhaust or silencing systems is required only in cases where the fibrous materials are in contact with exhaust gases because there is no possibility for the dispersion of fibrous materials under any other condition.
