| UN R51: Proposal for a Supplement 9 to the 03 series of amendments |
| Reference Number: GRBP-77-09 |
|
Proposal from the Informal Working Group on Measurement Uncertainties (IWG MU) to amend UN R51 with tables showing the measurement uncertainties when performing type-approval, COP, or field testing (e.g. market surveillance). The measurement uncertainties developed in this Appendix are based the IWG MU work and its Document for Reference which describes a general approach to estimate measurement uncertainties (GRBP/2022/9/Rev.2). The impact of the quantities on the expanded uncertainty has been evaluated separately for run-to-run, day-to-day, vehicle-to-vehicle and site-to-site variations. Some of the different impacts are based on calculations from tolerances in Annex 3, while others are based on experiences. |
