Designation:D836822Standard Test Method forDetermination of Totals of Aromatic,Polyaromatic and FattyAcid Methyl Esters(FAME)Content of Diesel Fuel UsingGas Chromatography with Vacuum Ultraviolet AbsorptionSpectroscopy Detection(GC-VUV)1This standard is issued under the fixed designation D8368;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.1.Scope*1.1 This test method covers a standard procedure for thedetermination of group type totals of aromatic,polyaromatic,and FAME content in diesel fuel using gas chromatographyand vacuum ultraviolet absorption spectroscopy detection(GC-VUV).1.1.1 Polyaromatic totals are the result of the summation ofdiaromatic and tri-plus aromatic group types.Aromatics are thesummation of monoaromatic and polyaromatic group types.FAME content is the result of summation of individual fattyacid methyl esters.1.1.2 This test method is applicable for renewable dieselfuels from hydrotreated vegetable oil(HVO)or animal fat,gasto liquid(GTL)diesel,light cycle oil,wide boiling rangearomatic solvents and biodiesel blends.1.2 Concentrations of group type totals are determined bypercent mass or percent volume.The applicable workingranges are as follows:Total Aromatics%Volume0.088 to 77.000Total Aromatics%Mass0.104 to 79.451MonoAromatics%Mass0.076 to 67.848Diaromatics%Mass0.027 to 34.812Tri-plus aromatics%Mass0.45 to 6.77PAH%Mass0.028 to 41.586FAME%Volume1.08 to 21.671.3 Diesel fuel containing biodiesel,(FAME,that is,fattyacid methyl esters including soy methyl esters,rapeseedmethylesters,tallow methylesters and canola methylesters)canbe analyzed by this test method.The FAME componentcompletely elutes from the analytical column independent offeedstock.1.4 Individual hydrocarbon components are not reported bythis test method;however,any individual component determi-nations are included in the appropriate summation of the totalsof aromatic,polyaromatic,monoaromatic,diaromatic,tri-plusaromatic,or FAME groups.1.4.1 Individual components are typically not baseline-separated by the procedure described in this test method.Thecoelutions are resolved at the detector using VUV absorbancespectra and deconvolution algorithms.1.5 This test method may apply to other hydrocarbonstreams boiling between heptane(98 C)and triacontane(450 C),but has not been extensively tested for such applica-tions.1.6 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.1.7 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.1.8 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.2.Referenced Documents2.1 ASTM Standards:2D4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4307 Practice for Preparation of Liquid Blends for Use asAnalytical StandardsD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System Performance1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.04.0L on Gas Chromatography Methods.Current edition approved Feb.1,2022.Published March 2022.Originallyapproved in 2021.Last previous edition approved in 2021 as D8368 21.DOI:10.1520/D8368-22.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*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.1D6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products,Liquid Fuels,and LubricantsD6730 Test Method for Determination of Individual Com-ponents in Spark Ignition Engine Fuels by 100-MetreCapillary(with Precolumn)Hig
