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.

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 receiving institution shall communicate the sending institution the results of each student at the end of each academic year. The parties agree that exams/courses shall be graded and awarded credits according to the rules of the institution where the exam/course is taken.
Validation of results. To validate the ReaxFF model it is compared to an electronic structure model (GFN1-xTB) as reference. To test the limits of our approach to compute activation free energies, the metadynamics free energies are compared to the potential energies for the gas phase system. Due to the small number of degrees of freedom in this test system, the difference between potential energy and free energy results is expected to be minimal, so that the two can be readily compared.
