Scope

1.1 This test method covers a high performance liquid chromatographic test method for the determination of monoaromatic and di-aromatic hydrocarbon contents in aviation kerosenes and petroleum distillates boiling in the range from 50 °C 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 applicable to distillates containing from 0.8 % to 44.0 % by mass mono-aromatic hydrocarbons, 0.23 % to 6.20 % by mass di-aromatic hydrocarbons, and 0.7 % to 50 % by mass total aromatics. Although this method generates results in m/m, results may also be quoted in v/v. 1.3 The precision of this test method has been established for kerosene boiling range distillates containing from 0.40 % to 44.0 % by mass mono-aromatic hydrocarbons, 0.02 % to 6.20 % by mass di-aromatic hydrocarbons, and 0.40 % to 50.0 % by mass total aromatics. If results are quoted in volume, the precision is 0.3 % to 41.4 % by volume mono-aromatics, 0.01 % to 5.00 % by volume di-aromatics, and 0.30 % to 46.3 % by volume total aromatics. As calculated by IP 367-1. 1.4 Compounds containing sulfur, nitrogen, and oxygen are possible interferents. Mono-alkenes do not interfere, but conjugated diand poly-alkenes, if present, are possible interferents. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. 1 This test method is under the jurisdiction of ASTM Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants and is the direct responsibility of Subcommittee D02.04.0C on Liquid Chromatography. The technically equivalent standard as referenced is under the jurisdiction of the Energy Institute Subcommittee SC-G-2. Current edition approved July 15, 2021. Published September 2021. Originally approved in 1999. Last previous edition approved in 2019 as D6379 – 11 (2019). DOI: 10.1520/D6379-21E01. 2 This test method has been developed through the cooperative effort between ASTM and the Energy Institute, London. ASTM and IP standards were approved by ASTM and EI technical committees as being technically equivalent but that does not imply both standards are identical. *A Summary of Changes section appears at the end of this standard Copyright © ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959.
