Designation:D734320Designation:558/07Standard Practice forOptimization,Sample Handling,Calibration,and Validationof X-ray Fluorescence Spectrometry Methods for ElementalAnalysis of Petroleum Products and Lubricants1This standard is issued under the fixed designation D7343;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 information relating to sampling,calibration and validation of X-ray fluorescence instrumentsfor elemental analysis,including all kinds of wavelengthdispersive(WDXRF)and energy dispersive(EDXRF)tech-niques.This practice includes sampling issues such as theselection of storage vessels,transportation,and sub-sampling.Treatment,assembly,and handling of technique-specificsample holders and cups are also included.Technique-specificrequirements during analytical measurement and validation ofmeasurement for the determination of trace elements insamples of petroleum and petroleum products are described.For sample mixing,refer to Practice D5854.Petroleum prod-ucts covered in this practice are considered to be a single phaseand exhibit Newtonian characteristics at the point of sampling.1.2 Applicable Test MethodsThis practice is applicable tothe XRF methods under the jurisdiction of ASTM Subcommit-tee D02.03 on Elemental Analysis,and those under thejurisdiction of the Energy Institutes Test Method Standardiza-tion Committee(Table 1).Some of these methods are techni-cally equivalent though they may differ in details(Table 2).1.3 Applicable FluidsThis practice is applicable to petro-leum and petroleum products with vapor pressures at samplingand storage temperatures less than or equal to 101 kPa(14.7 psi).Use Practice D4057 or IP 475 to sample thesematerials.Refer to Practice D5842 when sampling materialsthat also require Reid vapor pressure(RVP)determination.1.4 Non-applicable FluidsPetroleum products whose va-por pressure at sampling and sample storage conditions areabove 101 kPa(14.7 psi)and liquefied gases(that is,LNG,LPG,etc.)are not covered by this practice.1.5 Sampling MethodsThe physical sampling and meth-ods of sampling from a primary source are not covered by thisguide.It is assumed that samples covered by this practice area representative sample of the primary source liquid.Refer toPractice D4057 or IP 475 for detailed sampling procedures.1.6 The values stated in SI units are to be regarded asstandard.The values given in parentheses after SI units areprovided for information only and are not considered standard.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.1This 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 July 1,2020.Published July 2020.Originally approvedin 2007.Last previous edition approved in 2018 as D7343 18.DOI:10.1520/D7343-20.This practice was jointly prepared by ASTM International and the EnergyInstitute.*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.1.8 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:2D2622 Test Method for Sulfur in Petroleum Products byWavelength Dispersive X-ray Fluorescence SpectrometryD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4294 Test Method for Sulfur in Petroleum and PetroleumProducts by Energy Dispersive X-ray Fluorescence Spec-trometryD4927 Test Methods for Elemental Analysis of LubricantandAdditiveComponentsBarium,Calcium,Phosphorus,Sulfur,and Zinc by Wavelength-DispersiveX-Ray Fluorescence SpectroscopyD4929 Test Method for Determination of Organic ChlorideContent in Crude OilD5059 Test Methods for Lead and Manganese in Gasolineby X-Ray SpectroscopyD5842 Practice for Sampling and Handling of Fuels forVolatility Mea
