of the production defective is 0.l (consumer's risk
              = 10 per cent).
              3. For each of the pollutants given in Table 1 of paragraph 5.3.1.4. of this Regulation, the following procedure is used (see Figure 2 of this Regulation).
                Taking:
               L = the natural logarithm of the limit value for the pollutant,
               xi = the natural logarithm of the measurement for the i-th vehicle of the   sample,
               s = an estimate of the production standard deviation (after taking the   natural logarithm of the measurements),
               n = the current sample number.
              4.  Compute for the sample the test statistic quantifying the sum of the standard deviations from the limit and defined as:
5.  Then:
              5.1.  If the test statistic is greater than the pass decision number for the sample size given in Table 1/1 below, the pollutant is passed;
              5.2.  If the test statistic is less than the fail decision number for the sample size given in Table 1/1 below, the pollutant is failed; otherwise, an additional vehicle is tested and the calculation reapplied to the sample with a sample size one unit greater.
