GRB-62-15
Proposal for a supplement to UN Regulation No. 41 (IMMA)
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).
GRB/2015/8
Proposal for Supplement 4 to the 04 series of amendments to Regulation No. 41 (IMMA)
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.
