Designation:D832220Standard Test Method forDetermination of Elements in Residual Fuels and Crude Oilsby Microwave Plasma Atomic Emission Spectroscopy(MP-AES)1This standard is issued under the fixed designation D8322;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.Scope1.1 This test method covers the determination of metals andother elements in residual fuel and crude oil by microwaveplasma atomic emission spectroscopy(MP-AES).The specificelements within the scope of this method are V,Ni,Ca,Na,Al,Si,Zn,P,and S for residual fuel oil and Fe,V,Ni,Ca,Na,K,and S for crude oils.1.2 Method working range:high expected concentration limit=highest ILS sample meanlow expected concentration limit=lowest ILS sample mean if:(1)lowest ILS sample mean Rlowest ILS sample mean 0;otherwise it is determined by solving for X using the followingequation:(2)X RX=coarsest resolution,determined by0.5*r lowest ILS sample meanCrude Oil:ElementMethod Working Range(expected mg/kg)Iron0.70 to 161.02Vanadium2.88 to 417.50Nickel0.36 to 107.66Calcium5.41 to 96.78Sodium1.18 to 97.13Potassium7.01 to 63.83Sulfur1059 to 35194Residual Fuel Oil:ElementMethod Working Range(expected mg/kg)Vanadium3.88 to 370.09Nickel1.47 to 96.68Calcium4.41 to 102.01Sodium2.80 to 112.67Aluminum4.13 to 154.12Silicon5.99 to 237.56Zinc2.75 to 102.46Sulfur1314 to 301341.3 This test method uses soluble metals in organic solventsfor calibration and does not purport to quantitatively determineinsoluble particulates.Analytical results are particle sizedependent,and particles larger than a few micrometers maycause results to appear low1.4 Elements present at mass fractions above the upper limitof the calibration curves can be determined with additionalappropriate dilutions.Elements shall be measured at thewavelengths presented in Table 1.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.6 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.1.7 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:2D1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD1548 Test Method for Vanadium in Heavy Fuel Oil1(Withdrawn 1997)3D4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4175 Terminology Relating to Petroleum Products,LiquidFuels,and LubricantsD5708 TestMethodsforDeterminationofNickel,Vanadium,and Iron in Crude Oils and Residual Fuels by1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.03 on Elemental Analysis.Current edition approved June 1,2020.Published July 2020.DOI:10.1520/D8322-20.2For 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.Copyright 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.1Inductively Coupled Plasma(ICP)Atomic EmissionSpectrometryD6021 Test Method for Measurement of Total HydrogenSulfide in Residual Fuels by Multiple Headspace Extrac-tion and Sulfur Specific DetectionD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products,Liquid Fuels,and LubricantsD6792 Practice for Quality Management Systems in Petro-leum Products,Liquid Fuels,and Lubricants TestingLaboratoriesD7372 Guide for Analysis and Interpretation of ProficiencyTest Program Results2.2 ISO Standard:4ISO 85731 C
