Validation of results. The AD coefficient of variation is calculated as follows: (Standard deviation / Average) x 100. For the reference tyres (R): If the AD coefficient of variation of any two consecutive groups of three tests runs of the reference tyre set is higher than 3 per cent, all data should be discarded and the test repeated for all test tyres (the candidate tyres and the reference tyres). For the candidate tyres (T): The AD coefficients of variation are calculated for each candidate tyre set. If one coefficient of variation is higher than 3 per cent, the data should be discarded and the test repeated for that candidate tyre set.

Validation of results. The AD For the reference tyre: If the coefficient of variation is calculated as follows: (Standard deviation / Average) x 100. For the reference tyres (R): If the AD coefficient of variation "AD" of any two consecutive groups of three tests 3 runs of the reference tyre set is higher than 3 per cent, discard all data should be discarded and repeat the test repeated for all test tyres (the candidate tyres and the reference tyrestyre). The coefficient of variation is calculated by the following relation: standard deviation  100 average For the candidate tyres (T): tyres: The AD coefficients of variation are calculated for each all the candidate tyre settyres. standard deviation  100 average If one coefficient of variation is higher greater than 3 per cent, discard the data should be discarded and the test repeated for that this candidate tyre setand repeat the test.
