Regarding the vehicles or engines applying TCVN 6785:2015 or TCVN 6567:2015, the manufacturer shall determine the size n of the vehicles or engines; such vehicles or engines shall include those specified in paragraph 7.4 above. The arithmetical mean of the results obtained with the sample and the standard deviation S of the sample shall then be determined for each gaseous pollutant. The production of the series shall then be deemed to conform if the following condition is met:

Where:

L is the limit value for each gaseous pollutant, particulate and smoke considered;

 is any of the individual results obtained with the sample n;

The standard deviation S² = , x_i  is the result obtained with the sample i; k is a statistical factor depending on n and given in Table 11 below:
