Proposal to introduce requirements for non-original replacement exhaust silencing systems with multiple, manually or electronically adjustable, rider-selectable operating modes or variable geometries (NORESS with “flexibilities”). This is a consolidated version of the amended regulation with the changes marked in bold and strikethrough text.
10. The expert from Germany presented a new series of amendments to UN Regulation No. 92 which introduce requirements for non-original replacement exhaust silencing systems (NORESS). GRB adopted the proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their March 2019 sessions as a draft 02 series of amendments to UN Regulation No. 92.
29. The expert from Germany presented an overview of issues with noise emissions of non-original replacement exhaust silencer systems (NORESS) for L-category vehicles (GRB-67-03), as well as a possible solution in the form of a Supplement 3 to the 01 series to UN Regulation No. 92 (GRB-67-02). Following a brief exchange of views, GRB generally supported the approach and agreed that the proposed modifications should become a new series of amendments. GRB experts were invited to transmit their comments, if any, directly to the expert of Germany, so that he would be able to submit an official document for consideration at the next session.
