1、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
2、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 sul
3、furin 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
4、 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 k
5、g 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
6、 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 applic
