Designation:D734312Designation: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(14.7psi).Use Practice D4057 or IP 475 to sample these materials.Refer to Practice D5842 when sampling materials that alsorequire 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 as thestandard.The values given in parentheses are for informationonly.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 and health practices and determine the applica-bility of regulatory limitations prior to use.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 SpectroscopyD5059 Test Methods for Lead in Gasoline by X-Ray Spec-troscopyD5842 Practice for Sampling and Handling of Fuels forVolatility Measurement1This practice is under the jurisdiction of ASTM Committee D02 on PetroleumProducts and Lubricants and is the direct responsibility of Subcommittee D02.03 onElemental Analysis.Current edition approved Dec.1,2012.Published December 2012.Originallyapproved in 2007.Last previous edition approved in 2007 as D734307.DOI:10.1520/D7343-07.This practice was jointly prepared by ASTM International and the EnergyInstitute.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.*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 D5854 Practice for Mixing and Handling of Liquid Samplesof Petroleum and Petroleum ProductsD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceD6334 Test Method for Sulfur in Gasoline by WavelengthDispersive X-Ray FluorescenceD6443 Test Method for Determination of Calcium,Chlorine,Copper,Magnesium,Phosphorus,Sulfur,and Zinc inUnused Lubricating Oils and Additives by WavelengthDispersive X-ray Fluorescence Spectrometry(Mathemati-cal Correction Procedure)D6445 Test
