a batch being accepted with 75 per cent of the production defective is 0,15 (consumer's risk = 15 per cent).
              4.2. For each of the pollutants given in the Table 1of paragraph 5.3.1.4. of this Regulation, the following procedure is used (see Figure 4/2 below).
 Where:
 L       =  the limit value for the pollutant,
 xi      =  the value of the measurement for the i-th vehicle of the sample,
 n       =  the current sample number.

              4.3. The test statistic quantifying the number of non-conforming vehicles, i.e. xi > L, is computed for the sample.
              4.4. Then:
                  (i) If the test statistic does not exceed the pass decision number for the sample size given in the following table, a pass decision is reached for the pollutant;
                  (ii) If the test statistic equals or exceeds the fail decision number for the sample size given in the following table, a fail decision is reached for the pollutant;
                  (iii) Otherwise, an additional vehicle is tested and the procedure is applied to the sample with one extra unit.
               In the following table the pass and fail decision numbers are computed in  accordance with the International Standard ISO 8422:1991.
              5.  A sample is regarded as having passed the test when it has passed both the requirements of paragraphs 3. and 4. of this appendix.
