Designation:D745519Standard Practice forSample Preparation of Petroleum and Lubricant Productsfor Elemental Analysis1This standard is issued under the fixed designation D7455;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 practice covers different means by which petro-leum product and lubricant samples may be prepared before themeasurement of their elemental content using different analyti-cal techniques.1.2 This practice includes only the basic steps for generallyencountered sample types.Anything out of the ordinary mayrequire special procedures.See individual test methods forinstructions to handle such situations.1.3 This practice is not a substitute for a thorough under-standing of the actual test method to be used,caveats the testmethod contains,and additional sample preparation that maybe required.1.4 The user should not expand the scope of the testmethods to materials or concentrations outside the scope of thetest methods being used without thoroughly understanding theimplications of such deviations.1.5 This practice may also be applicable to sample prepa-ration of non-petroleum based bio-fuels for elemental analysis.Currently,work is ongoing inASTM Subcommittee D02.03;asinformation becomes available,it will be added to this stan-dard.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 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.1.8 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:2C1234 Practice for Preparation of Oils and Oily WasteSamples by High-Pressure,High-Temperature Digestionfor Trace Element DeterminationsD86 Test Method for Distillation of Petroleum Products andLiquid Fuels at Atmospheric PressureD129 Test Method for Sulfur in Petroleum Products(Gen-eral High Pressure Decomposition Device Method)D482 Test Method for Ash from Petroleum ProductsD808 Test Method for Chlorine in New and Used PetroleumProducts(High Pressure Decomposition Device Method)D874 Test Method for Sulfated Ash from Lubricating Oilsand AdditivesD1018 Test Method for Hydrogen In Petroleum FractionsD1091 Test Methods for Phosphorus in Lubricating Oils andAdditivesD1266 Test Method for Sulfur in Petroleum Products(LampMethod)D1318 Test Method for Sodium in Residual Fuel Oil(FlamePhotometric Method)D1548 Test Method for Vanadium in Heavy Fuel Oil1(Withdrawn 1997)3D1552 Test Method for Sulfur in Petroleum Products byHigh Temperature Combustion and Infrared(IR)Detec-tion or Thermal Conductivity Detection(TCD)D2622 Test Method for Sulfur in Petroleum Products byWavelength Dispersive X-ray Fluorescence SpectrometryD2784 Standard Test Method for Sulfur in Liquefied Petro-leum Gases(Oxy-Hydrogen Burner or Lamp)(Withdrawn2016)3D3120 Test Method for Trace Quantities of Sulfur in LightLiquid Petroleum Hydrocarbons by Oxidative Microcou-lometry1This practice is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.03 on Elemental Analysis.Current edition approved May 1,2019.Published May 2019.Originallyapproved in 2008.Last previous edition approved in 2014 as D7455 14.DOI:10.1520/D7455-19.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.*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 D3228 Test Method for Total Nitrogen in Lubricating Oilsand Fuel Oils by Modified Kjeldahl MethodD3230 Test Method for Salts in Crude Oil(ElectrometricMethod)D3231 Test Method for Phosphoru
