follows:
               (a) The pollutant emissions (type I) will be measured at zero and at "x"   km on the first tested vehicle;
               (b) The evolution coefficient of the emissions between zero and "x" km   will be calculated for each of the pollutants:

               This may be less than 1,
               (a) The other vehicles will not be run in, but their zero km emissions will   be multiplied by the evolution coefficient.
               In this case, the values to be taken will be:
               (a) The values at "x" km for the first vehicle;
               (b) The values at zero km multiplied by the evolution coefficient for the   other vehicles.
