UN R51: Draft proposal for Supplement 9 to the 03 series of amendments

Reference Number: IWGMU-22-08/Rev.1

Draft proposal to introduce a new Annex 10 (“Estimation of the calculation of the expanded measurement uncertainties for sound measurements of Annex 3 for vehicles of category M and N”) to provide tables showing the measurement uncertainties when performing type-approval, Conformity of Production, and/or field testing (e.g. market surveillance). This work is associated with the “Document for Reference” which describes a general approach to estimating measurement uncertainties (GRBP/2022/9/Rev.1 pending consideration of Revision 2).
