Designation:D155216(Reapproved 2021)Standard Test Method forSulfur in Petroleum Products by High TemperatureCombustion and Infrared(IR)Detection or ThermalConductivity Detection(TCD)1This standard is issued under the fixed designation D1552;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.Scope1.1 This test method covers procedures for the determina-tion of total sulfur in petroleum products including lubricatingoils containing additives,and in additive concentrates.This testmethod is applicable to samples boiling above 177 C(350 F)and containing a mass fraction of sulfur between 0.22%and24.2%.Other sulfur concentrations may be analyzed,but theprecision stated may or may not apply.These procedures useIR detection or TCD following combustion in a furnace.1.2 Petroleum coke containing a mass fraction of sulfurbetween 2.53%to 3.79%sulfur may be analyzed.Other sulfurconcentrations may be analyzed,but the precision stated mayor may not apply.NOTE1The D1552 08(2014)version of this standard contained twoother procedures using iodate titrations.Since these procedures are nolonger being used in the industry laboratories based on a survey ofD02.SC 3 laboratories conducted in September 2014,they are beingdeleted.For earlier information on the deleted procedures,D1552 08(2014)may be perused.1.3The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.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.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:2D4057 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 PerformanceD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products,Liquid Fuels,and LubricantsD6792 Practice for Quality Management Systems in Petro-leum Products,Liquid Fuels,and Lubricants TestingLaboratories3.Summary of Test Method3.1 The sample is weighed and placed into a furnace havingan oxygen atmosphere sufficient to combust the entire sampleand a temperature between 1150 C and 1450 C for ProcedureA or 1150 C for Procedure B.Most sulfur present is com-busted to SO2,which is then measured with a detector aftermoisture and dust are removed by traps.The instrumentcalculates the mass percent sulfur from the sample mass,theintegrated detector signal,and a predetermined calibrationfactor.The calibration factor is determined using standardsapproximating the material to be analyzed.3.1.1 Procedure AAfter combustion of the sample andsubsequent moisture/dust removal,SO2is measured usinginfrared(IR)detection.3.1.2 Procedure BAfter combustion of the sample andsubsequent moisture/dust removal,SO2is measured usingthermal conductivity detection.An apparatus utilizing TCDmay require the sample gas to pass an oxygen scrubber and1This 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 1,2021.Published July 2021.Originally approvedin 1958.Last previous edition approved in 2016 as D1552 161.DOI:10.1520/D1552-16R21.2For 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.Copyright 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.1adsorption/desorption traps to allow passing of contaminantsprior to measuring SO2.4.Significance and Use4.1 This test me
