The purpose is to ensure that the target test speed is either 10 km/h, or 20 km/h, in forward motion, or 6 km/h in reverse motion and that the tolerances given by the regulation are linked to the testing and not used for more favorable testing speed. |

| 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. |
