I princip utförs utsläppsberäkningen så här: Partiets provkoncentrationer multipliceras med den totala avgasmassan eller massflödet (outspätt eller utspätt) från vilket de togs ut under provcykeln. ###>In principal the method of emission calculation is done as follows: the batch sampled concentrations are multiplied by the total mass or mass flow (raw or dilute) from which it was extracted during the test cycle.
