Correction to paragraph 6.2.2. “Sound level limits” to add a reference specifically to paragraph 3.1 of Annex 3 in order to ensure interpretation of the sound limit values as application only “noise in motion” and not to “stationary noise”. This aligns the 02 and 03 series texts.

Proposal for clarifications, including the applicability of certain provisions, in Annex 3: Methods and instruments for measuring the sound made by motor vehicles.

Presentation for discussion of specific technical questions concerning the application of UN 51 test procedures.

Proposal to clarify the wording of the 03 series of amendments to UN R51 as adopted by the World Forum in June 2015 (document WP.29/2015/62). The adopted wording could lead to the interpretation that sound levels measured on the left side of the vehicle are to be averaged with levels measured on the right side of the vehicle. The proposed new wording clarifies that the overall sound emission is assessed individually per vehicle side.

Proposal including indoor testing as an alternative to type approval tests of Annex 3 to Regulation No. 51 in accordance with ISO 26101:2012 and ISO 362-3.
