Designation:D131918Standard Test Method forHydrocarbon Types in Liquid Petroleum Products byFluorescent Indicator Adsorption1This standard is issued under the fixed designation D1319;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This test method covers the determination of hydrocar-bon types over the concentration ranges from 5%to 99%byvolume aromatics,0.3%to 55%by volume olefins,and 1%to 95%by volume saturates in petroleum fractions that distillbelow 315 C.This test method may apply to concentrationsoutside these ranges,but the precision has not been determined.Samples containing dark-colored components that interfere inreading the chromatographic bands cannot be analyzed.NOTE1For the determination of olefins below 0.3%by volume,othertest methods are available,such as Test Method D2710.1.2 This test method is intended for use with full boilingrange products.Cooperative data have established that theprecision statement does not apply to narrow boiling petroleumfractions near the 315 C limit.Such samples are not elutedproperly,and results are erratic.1.3 This test method includes a relative bias section basedon Practice D6708 accuracy assessment between Test MethodD1319 and Test Method D5769 for total aromatics in spark-ignition engine fuels as a possible Test Method D1319 alter-native to Test Method D5769 for U.S.EPA spark-ignitionengine fuel regulations reporting.The Practice D6708 derivedcorrelation equation is only applicable for fuels in the totalaromatic concentration range from 3.3%to 34.4%by volumeas measured by Test Method D1319 and the distillationtemperature T95,at which 95%of the sample has evaporated,ranges from 149.1 C to 196.6 C(300.3 F to 385.8 F)whentested according to Test Method D86.1.3.1 The applicable Test Method D5769 range for totalaromatics is 3.7%to 29.4%by volume as reported by TestMethod D5769 and the distillation temperature T95values,atwhich 95%of the sample has evaporated,when testedaccording to Test Method D86 is from 149.1 C to 196.6 C(300.3 F to 385.8 F).1.4 The applicability of this test method to products derivedfrom fossil fuels other than petroleum,such as coal,shale,ortar sands,has not been determined,and the precision statementmay or may not apply to such products.1.5 This test method has two precision statements depictedin tables.The first table is applicable to unleaded fuels that donot contain oxygenated blending components.It may or maynot apply to automotive gasolines containing lead antiknockmixtures.The second table is applicable to oxygenate blended(for example,MTBE,ethanol)automotive spark ignition fuelsamples with a concentration range of 13%to 40%by volumearomatics,4%to 33%by volume olefins,and 45%to 68%by volume saturates.1.6 The oxygenated blending components,methanol,ethanol,methyl-tert-butylether(MTBE),tert-amylmethylether(TAME),and ethyl-tert-butylether(ETBE),do not interferewith the determination of hydrocarbon types at concentrationsnormally found in commercial blends.These oxygenatedcomponents are not detected since they elute with the alcoholdesorbent.Other oxygenated compounds shall be individuallyverified.When samples containing oxygenated blending com-ponents are analyzed,correct the results to a total-sample basis.1.7 WARNINGMercury has been designated by manyregulatory agencies as a hazardous substance that can causeserious medical issues.Mercury,or its vapor,has been dem-onstrated to be hazardous to health and corrosive to materials.Use Caution when handling mercury and mercury-containingproducts.See the applicable product Safety Data Sheet(SDS)for additional information.The potential exists that sellingmercury or mercury-containing products,or both,is prohibitedby local or national law.Users must determine legality of salesin their location.1.8 The values stated in SI units are to be regarded asstandard.The values given in parentheses after SI units areprovided for information only and are not considered standard.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.Current edition approved Oct.1,2018.Published December 2018.Originallyapproved in 1954.Last previous edition approved in 2015 as D1319 15.DOI:10.1520/D1319-18.*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 theDevelopme
