3. The expert from Italy, chairing the informal group on Regulation No. 41, recalled the discussion of GRB at its previous session (ECE/TRANS/WP.29/GRB/2009/3 and GRB-51-16) and reported on the progress of work made by the informal group during its meeting on 1 June 2010. Referring to the working papers available on the website http://www.unece.org/trans/main/wp29/wp29wgs/wp29grb/R41-14th.html, he informed GRB that the informal group could find an agreement on:
(a) an additional or enlarged plate;
(b) the new type approval test method for measuring the noise levels including provisions for anti-tampering; and
© the Additional Sound Emission Provisions (ASEP) including the so called mystery points.

4. He announced the informal group’s intention to finalize the draft 04 series of amendments to Regulation No. 41 and to submit the proposal, as an official document, to GRB for a detailed consideration at its next session in February 2011. For this purpose, all GRB experts were invited to send their comments at latest by the end of September 2010 to the Secretary of the informal group (erwin.segers@honda-eu.com).

5. On the new limit values for the noise emissions of motorcycles, GRB welcomed the initiative of the informal group to set up a data base to collect type approval data on current noise levels.

6. The expert from ISO introduced ECE/TRANS/WP.29/GRB/2010/7 proposing a clarification to the stationary noise testing provisions with regard to vehicles in which the internal combustion engine does not operate during the stationary conditions. GRB adopted the proposal and agreed to submit it to WP.29 and AC.1 for consideration at their June 2011 sessions, together with the draft 04 series of amendments to Regulation No. 41 (see para. 4 above).
