The μ peak coefficient of variation is calculated as follows:
(Standard Deviation / Average) x 100
For the reference tyre (R) For the candidate tyre(s) (T)
If the coefficient of variation of the peak braking force coefficient ( μ peak ) of the reference tyre is higher than 5 %, all data should be discarded and the test repeated for all test tyres (the candidate tyre(s) and the reference tyre).
The coefficient of variation of the peak braking force coefficient ( μ peak ) is calculated for each candidate tyre. If one coefficient of variation is higher than 5 %, the data should be discarded and the test repeated for this candidate tyre.
