Designation:D757818Standard Guide forCalibration Requirements for Elemental Analysis ofPetroleum Products and Lubricants1This standard is issued under the fixed designation D7578;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 guide covers different ways by which the testmethods used for elemental analysis of petroleum product andlubricant samples are calibrated before the sample analysis.1.2 Uniform practice for test method calibration is benefi-cial in standardizing the procedures,and obtaining consistentresults across different laboratories.1.3 This guide includes only the basic steps for generallyencountered instrument types.Anything out of the ordinarymay require special procedures.See individual test methods forinstructions to handle such situations.1.4 This guide is not a substitute for a thorough understand-ing of the actual test method to be used,caveats it contains,andadditional instrument preparation that may be required.1.5 The user should not expand the scope of the testmethods to materials or concentrations outside the scope of thetest methods being used.1.6 This guide should also be applicable to sample prepa-ration of non-petroleum based bio-fuels for elemental analysis.Work is underway on these aspects in Subcommittee D02.03.As more information becomes available,it will be added to thisstandard.1.7 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.8 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.1.9 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:2D129 Test Method for Sulfur in Petroleum Products(Gen-eral High Pressure Decomposition Device Method)D445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)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 AdditivesD892 Test Method for Foaming Characteristics of Lubricat-ing OilsD1018 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)D1839 Test Method for Amyl Nitrate in Diesel FuelsD2622 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)31This guide 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 June 1,2018.Published June 2018.Originallyapproved in 2010.Last previous edition approved in 2015 as D7578 15.DOI:10.1520/D7578-18.2For 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 D3120 Test Method for Trace Quantities of Sulfur in LightLiquid Petroleum Hydrocarbons by Oxidative Microcou-lometryD3228 Test Method for Total Nitrogen in Lubricating Oilsand Fuel Oils by Modified Kjeldahl MethodD3230 Test Method for Sal
