Designation:D6379211Designation:436/20Standard Test Method forDetermination of Aromatic Hydrocarbon Types in AviationFuels and Petroleum DistillatesHigh Performance LiquidChromatography Method with Refractive Index Detection1,2This standard is issued under the fixed designation D6379;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEEditorially corrected 9.4.3.1 in October 2021.INTRODUCTIONThis test method is intended to be technically equivalent to IP 436-20 with an identical title.TheASTM format for test methods has been used,and where possible,equivalent ASTM test methodshave replaced the IP or ISO standards.The test method is intended to be used as one of several possible alternative instrumental testmethods that are aimed at quantitative determination of hydrocarbon types in fuels.This does notimply that a correlation necessarily exists between this and any other test method intended to give thisinformation,and it is the responsibility of the user to determine such correlation if necessary.1.Scope*1.1 This test method covers a high performance liquidchromatographic test method for the determination of mono-aromatic and di-aromatic hydrocarbon contents in aviationkerosenes and petroleum distillates boiling in the range from50 C to 300 C,such as Jet A or Jet A-1 fuels.The totalaromatic content is calculated from the sum of the individualaromatic hydrocarbon-types.NOTE1Samples with a final boiling point greater than 300 C thatcontain tri-aromatic and higher polycyclic aromatic compounds are notdetermined by this test method and should be analyzed by Test MethodD6591 or other suitable equivalent test methods.1.2 This test method is applicable to distillates containingfrom 0.8%to 44.0%by mass mono-aromatic hydrocarbons,0.23%to 6.20%by mass di-aromatic hydrocarbons,and0.7%to 50%by mass total aromatics.Although this methodgenerates results in m/m,results may also be quoted in v/v.1.3 The precision of this test method has been establishedfor kerosene boiling range distillates containing from 0.40%to44.0%by mass mono-aromatic hydrocarbons,0.02%to6.20%by mass di-aromatic hydrocarbons,and 0.40%to50.0%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%to46.3%by volume total aromatics.As calculated by IP 367-1.1.4 Compounds containing sulfur,nitrogen,and oxygen arepossible interferents.Mono-alkenes do not interfere,but con-jugated di-and poly-alkenes,if present,are possible interfer-ents.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.04.0C on Liquid Chromatography.The technically equivalentstandard as referenced is under the jurisdiction of the Energy Institute SubcommitteeSC-G-2.Current edition approved July 15,2021.Published September 2021.Originallyapproved in 1999.Last previous edition approved in 2019 as D6379 11(2019).DOI:10.1520/D6379-21E01.2This test method has been developed through the cooperative effort betweenASTM and the Energy Institute,London.ASTM and IP standards were approved byASTM and EI technical committees as being technically equivalent but that does notimply both standards are identical.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.12.Referenced Documents2.1 ASTM Standards:3D4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD6591 Test Method for Determination of Aromatic Hydro-carbon Types in Middle Distillate
