Common use of Validation of results Clause in Contracts

Validation of results. For the candidate tyres: The coefficient of variation CVAA of the average acceleration is calculated according to the formula in 4.7.5.4. of this Annex for all the candidate tyres. If one coefficient of variation is greater than 6 per cent, discard the data for this candidate tyre and repeat the test. For the reference tyre: If the coefficient of variation CVAA of the average acceleration calculated according to the formula in 4.7.5.4. of this Annex for each group of min 6 runs of the reference tyre is higher than 6 per cent, discard all data and repeat the test for all tyres (the candidate tyres and the reference tyre). In addition and in order to take in account possible test evolution, the coefficient of validation CValAA(SRTT) is calculated on the basis of the average values of any two consecutive groups of minimum 6 runs of the reference tyre according to If the coefficient of validation is greater than 6 per cent, discard the data for all the candidate tyres and repeat the test.
