Scope: This standard specifies the mass spectrometry analysis method, quantitative calculation process and analysis precision of aromatic hydrocarbons in heavy fraction petroleum. This standard is applicable to the quantitative analysis of the hydrocarbon group composition of 18 aromatic hydrocarbons and 3 aromatic thiophenes in the aromatic fraction of heavy distillate petroleum (boiling range 300°C to 540°C). There should be no olefins in the sample, the total sulfur content must be less than 1% of the total weight, and the non-aromatic content should be <5%.
