Designation:D126613Designation:107/86Standard Test Method forSulfur in Petroleum Products(Lamp Method)1This standard is issued under the fixed designation D1266;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 total sulfurin liquid petroleum products in concentrations from 0.01 to 0.4mass%(Note 1).A special sulfate analysis procedure isdescribed in Annex A1 that permits the determination of sulfurin concentrations as low as 5 mg/kg.NOTE1The comparable lamp method for the determination of sulfurin liquefied petroleum gas is described in Test Method D2784.For thedetermination of sulfur in heavier petroleum products that cannot beburned in a lamp,see the high pressure decomposition device method(Test Method D129)the quartz tube method(IP 63),or the high-temperature method(Test Method D1552).1.2 The direct burning procedure(Section 9)is applicable tothe analysis of such materials as gasoline,kerosine,naphtha,and other liquids that can be burned completely in a wick lamp.The blending procedure(Section 10)is applicable to theanalysis of gas oils and distillate fuel oils,naphthenic acids,alkyl phenols,high sulfur content petroleum products,andmany other materials that cannot be burned satisfactorily by thedirect burning procedure.1.3 Phosphorus compounds normally present in commercialgasoline do not interfere.A correction is given for the smallamount of acid resulting from the combustion of the leadanti-knock fluids in gasolines.Appreciable concentrations ofacid-forming or base-forming elements from other sourcesinterfere when the titration procedure is employed since nocorrection is provided in these cases.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D129 Test Method for Sulfur in Petroleum Products(Gen-eral High Pressure Decomposition Device Method)D1193 Specification for Reagent WaterD1552 Test Method for Sulfur in Petroleum Products(High-Temperature Method)D2784 Test Method for Sulfur in Liquefied Petroleum Gases(Oxy-Hydrogen Burner or Lamp)D6299 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 andLubricantsD6792 Practice for Quality System in Petroleum Productsand Lubricants Testing LaboratoriesE11 Specification for Woven Wire Test Sieve Cloth and TestSieves2.2 Energy Institute Standard:3IP 63 Sulfur ContentThe Quartz Tube Method3.Summary of Test Method3.1 The sample is burned in a closed system,using asuitable lamp(Fig.1)and an artificial atmosphere composed of70%carbon dioxide and 30%oxygen to prevent formation ofnitrogen oxides.The oxides of sulfur are absorbed and oxi-dized to sulfuric acid by means of hydrogen peroxide solutionwhich is then flushed with air to remove dissolved carbondioxide.Sulfur as sulfate in the absorbent is determined1This 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 June 15,2013.Published August 2013.Originallyapproved in 1969.Last previous edition approved in 2007 as D1266 07.DOI:10.1520/D1266-13.2For 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.3Available from Energy Institute,61 New Cavendish St.,London,WIG 7AR,U.K.,http:/www.energyinst.org.uk.*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 States1 acidimetrically by titration with standard sodium hydroxidesolution,or gravimetrically by precipitation as barium sulfate(see Annex A2).3.2 Alternatively,the sample may be burned in air,thesulfur as sulfate in the absorbent being determined by precipi-tation as barium sulfate for weighing(see Annex A2).NOTE2In the absence of acid-forming or base-forming elements,other than sulfur,results by the volumetric and gravimetric finishesdescribed are equivalent within the
