Common use of Validation of results Clause in Contracts

Validation of results. For the reference tyre: If the coefficient of variation of the peak braking coefficient CVµ of the reference tyre, which is calculated by the formula given in 4.2.8.2. of part (A) of this Annex, is higher than five per cent, discard all data and repeat the test for this reference tyre. For the candidate tyres: The coefficients of variation CVµ are calculated for all the candidate tyres according to the formula in 4.2.8.2. of part (A) of this Annex. If one coefficient of variation is greater than five per cent, discard the data for this candidate tyre and repeat the test. If R1 is the average of the peak braking coefficient in the first test of the reference tyre, R2 is the average of the peak braking coefficient in the second test of the reference tyre, the following operations are performed, according to the following table:
