Designation:D545319aStandard Test Method forDetermination of Total Sulfur in Light Hydrocarbons,SparkIgnition Engine Fuel,Diesel Engine Fuel,and Engine Oil byUltraviolet Fluorescence1This standard is issued under the fixed designation D5453;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 the determination of total sulfurin liquid hydrocarbons,boiling in the range from approxi-mately 25 C to 400 C,with viscosities between approxi-mately 0.2 cSt and 20 cSt(mm2/s)at room temperature.1.2 Three separate interlaboratory studies(ILS)onprecision,and three other investigations that resulted in anASTM research report,have determined that this test method isapplicable to naphthas,distillates,engine oil,ethanol,FattyAcid Methyl Ester(FAME),and engine fuel such as gasoline,oxygen enriched gasoline(ethanol blends,E-85,M-85,RFG),diesel,biodiesel,diesel/biodiesel blends,and jet fuel.Samplescontaining 1.0 mgkg to 8000 mg kg total sulfur can be ana-lyzed(Note 1).NOTE1Estimates of the pooled limit of quantification(PLOQ)for theprecision studies were calculated.Values ranged between less than1.0 mg kg and less than 5.0 mg kg(see Section 9 and 16.1).1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 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.For warning statements,see 3.1,7.3,7.4,Section 8,and 9.1.1.5 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:2D1250 Guide for Use of the Petroleum Measurement TablesD1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD4052 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 ProductsD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System Performance3.Summary of Test Method3.1 A hydrocarbon sample is either directly injected orplaced in a sample boat.The sample or boat,or both,is insertedinto a high temperature combustion tube where the sulfur isoxidized to sulfur dioxide(SO2)in an oxygen rich atmosphere.Water produced during the sample combustion is removed andthe sample combustion gases are next exposed to ultraviolet(UV)light.The SO2absorbs the energy from the UV light andis converted to excited sulfur dioxide(SO2*).The fluorescenceemitted from the excited SO2*as it returns to a stable state,SO2,is detected by a photomultiplier tube and the resultingsignal is a measure of the sulfur contained in the sample.(WarningExposure to excessive quantities of ultraviolet(UV)light is injurious to health.The operator must avoidexposing any part of their person,especially their eyes,notonly to direct UV light but also to secondary or scatteredradiation that is present.)4.Significance and Use4.1 Some process catalysts used in petroleum and chemicalrefining can be poisoned when trace amounts of sulfur bearing1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.03 on Elemental Analysis.Current edition approved July 1,2019.Published August 2019.Originallyapproved in 1993.Last previous edition approved in 2019 as D5453 19.DOI:10.1520/D5453-19A.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.1 materials are contained in
