1.1 ,This test method covers a high performance liquid chromatographic test method for the determination of mono-aromatic, di-aromatic, tri+-aromatic, and polycyclic aromatic hydrocarbon contents in diesel fuels and petroleum distillates boiling in the range from 150 ,°,C to 400 ,°,C. The total aromatic content in % m/m is calculated from the sum of the corresponding individual aromatic hydrocarbon types.
Note 1: ,Aviation fuels and petroleum distillates with a boiling point range from 50 ,°,C to 300 ,°,C are not determined by this test method and should be analyzed by Test Method D6379 or other suitable equivalent test methods.
