Designation:D711116(Reapproved 2021)Standard Test Method forDetermination of Trace Elements in Middle Distillate Fuelsby Inductively Coupled Plasma Atomic EmissionSpectrometry(ICP-AES)1This standard is issued under the fixed designation D7111;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 selectedelements in middle distillate fuels by inductively coupledplasma atomic emission spectrometry(ICP-AES).The specificelements are listed in Table 1.The concentration range of thistest method is approximately 0.1 mg kg to 2.0 mg/kg.The testmethod may be used for concentrations outside of this range;however,the precision statements may not be applicable.Middle distillate fuels covered in this test method have alldistillation fractions contained within the boiling range of150 C to 390 C.This includes,but is not limited to,dieselfuels and aviation turbine fuels.1.2 This test method is not intended to analyze insolubleparticulates.However,very small particulate matter(smallerthan a micrometre)will be carried into the plasma and beincluded in the quantitative analysis.1.3 This test method may give a result that is higher than thetrue value if an analyte is present in the sample in a form whichis sufficiently volatile.For example,hexamethyldisiloxane willgenerate a biased high result for silicon.1.4 The values stated in SI units are to be regarded asstandard.1.5 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.1.6 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:2D2880 Specification for Gas Turbine Fuel OilsD3605 Test Method for Trace Metals in Gas Turbine Fuelsby Atomic Absorption and Flame Emission SpectroscopyD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4306 Practice for Aviation Fuel Sample Containers forTests Affected by Trace ContaminationD5185 Test Method for Multielement Determination ofUsed and Unused Lubricating Oils and Base Oils byInductively Coupled Plasma Atomic Emission Spectrom-etry(ICP-AES)D6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceD6792 Practice for Quality Management Systems in Petro-leum Products,Liquid Fuels,and Lubricants TestingLaboratoriesD7260 Practice for Optimization,Calibration,and Valida-tion of Inductively Coupled Plasma-Atomic EmissionSpectrometry(ICP-AES)for Elemental Analysis of Petro-leum Products and Lubricants2.2 Military Standard:MIL-DTL-16884 Fuel,Naval Distillate33.Terminology3.1 Definitions:3.1.1 calibration,nthe determination of the values of thesignificant parameters by comparison with values indicated bya set of reference standards.3.1.2 calibration curve,nthe graphical or mathematicalrepresentation of a relationship between the assigned(known)values of standards and the measured responses from themeasurement system.1This 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 July 1,2021.Published August 2021.Originallyapproved in 2005.Last previous edition approved in 2016 as D7111 16.DOI:10.1520/D7111-16R21.2For 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.3Available online at http:/quicksearch.dla.mil or http:/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.3.1.3 calibration standard,na standard having an ac-cepted value(reference value)for use in calibrating a measure-ment instrument or system.3.1.4 detection limit,na stated limiting value that desig-nates the lowest concentration that can be determined withconfidence an
