EN Regulation 715/2007 determines two levels of requirements as regards emission of pollutants: Euro 5 and Euro 6. In its Regulation 692/2008 the European Commission divided each of those levels into two subsets marked with the letters “a” and “b” (Euro 5a, Euro 5b, Euro 6a, Euro 6b). This further division was introduced in connection with the change of the measurement methodology of PM emissions. The letter “a” denotes a method identical to the one used in Euro 4, while the letter “b” denotes a new method, suitable for measuring low PM values in exhaust gases. The first method was valid until 31.09.2011 for NTA and until 31.12.2012 for ANR, while the other one took effect thereafter.
