Significance and Use
Accurate quantitative information on aromatic hydrocarbon types can be useful in determining the effects of petroleum processes on production of various finished fuels. This information can also be useful for indicating the quality of fuels and for assessing the relative combustion properties of finished fuels.
1.1 This test method covers a high performance liquid chromatographic test method for the determination of mono-aromatic and di-aromatic hydrocarbon contents in aviation kerosines and petroleum distillates boiling in the range from 50 to 300°C, such as Jet A or Jet A-1 fuels. The total aromatic content is calculated from the sum of the individual aromatic hydrocarbon-types.
Note 1—Samples with a final boiling point greater than 300°C that contain tri-aromatic and higher polycyclic aromatic compounds are not determined by this test method and should be analyzed by Test Method D6591 or other suitable equivalent test methods.
1.2 This test method is calibrated for distillates containing from 10 to 25 % m/m mono-aromatic hydrocarbons and from 0 to 7 % m/m di-aromatic hydrocarbons.
1.3 The precision of this test method has been established for kerosine boiling range distillates containing from 10 to 25 % m/m mono-aromatic hydrocarbons and from 0 to 7 % m/m di-aromatic hydrocarbons.
1.4 Compounds containing sulfur, nitrogen, and oxygen are possible interferents. Mono-alkenes do not interfere, but conjugated di- and poly-alkenes, if present, are possible interferents.
1.5 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
