  "text": "In order to establish a measured evolution coefficient with a run-in vehicle the procedure shall be as follows:\n(a)the pollutants/CO2 shall be measured at a mileage of at most 80 km and at ‘x’ km of the first tested vehicle;\n(b)the evolution coefficient (EvC) of the pollutants/CO2 between 80 km and ‘x’ km shall be calculated as:\nEvCmeas=values at‘x’ km∕values at 80 km\n(c)the other vehicles in the COP family shall not be run in, but their zero km emissions/EC/CO 2 shall be multiplied by the evolution coefficient of the first run-in vehicle. In this case, the values to be taken for testing as in Appendix 1 shall be:\n(i)the values at ‘x’ km for the first vehicle;\n(ii)the values at zero km multiplied by the relevant evolution coefficient for the other vehicles.",
