UN R51: Proposal to introduce a Temperature Correction for the Tyre Rolling Sound Component of Pass-by Tests

Reference Number: GRBP-74-13

IWG on Measurement Uncertainties identified the temperature behaviour of tyre rolling sound component as a contributor to the measurement uncertainty of pass-by noise tests. Since in UN Reg. No.117 a temperature correction of tyre rolling sound is already established the group investigated an adoption of the existing calculation procedure. Due to the different testing conditions in UN Reg. No.117, new scientific investigations and industry data in pass-by testing the group worked out a temperature correction, which is adopted to the requirements of UN Reg. No.51.

Meeting Sessions: 74th GRBP session (15-17 Sep 2021), 10th UNR51-DG session (21 Sep 2021), and 13th TFMU session (13 Jul 2021)
