Designation:D831520Standard Test Method forDetermination of Wear Metals and Contamination Elementsin Used Industrial Oils by Sweeping Flat Electrode AtomicEmission Spectrometry1This standard is issued under the fixed designation D8315;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 wearmetals and contaminants in used industrial oils by sweepingflat electrode atomic emission spectroscopy(SFE-AES).21.2 Industrial oil includes lubricant oil,gear box oil,hy-draulic fluid,compressor oil,turbine oil,synthetic oils,andother petroleum oils.1.3 Method working range for every element is evaluated byequations in 15.2.1 and tabulated in Table 6.1.4 Though this technique is designed to analyze non-suspended particles in lubricant samples,the precision state-ments published here were established solely from homoge-neous oil samples per Practice D6300 requirements.Non-suspended particles,which are inhomogeneous by nature,werenot sampled and evaluated for deriving precision statements forthis test method(see Annex A1).1.5 This test method provides a quick indication for abnor-mal wear and the presence of contamination in new or usedindustrial oils by immediately reporting:1.5.1 Normal fine particles of specific wear metals;1.5.2 Non-suspendable particles of specific wear metals andof contamination elements;1.5.3 Less populated large particles(10 m to 50 m)ofspecific wear metals;1.5.4 Contamination elements;and1.5.5 Additive elements.1.6 This test method uses oil-soluble elements for calibra-tion and does not purport to relate quantitatively the valuesdetermined as insoluble particles to the dissolved metals.Analytical results are particle size dependent and low resultsmay be obtained for those elements present in used oil samplesas large particles(referenced by Test Methods D5185 andD6595).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:3D4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD5185 Test Method for Multielement Determination ofUsed and Unused Lubricating Oils and Base Oils byInductively Coupled Plasma Atomic Emission Spectrom-etry(ICP-AES)D6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products,Liquid Fuels,and LubricantsD6595 Test Method for Determination of Wear Metals andContaminants in Used Lubricating Oils or Used HydraulicFluids by Rotating Disc ElectrodeAtomic Emission Spec-trometry1This 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/D8315-20.2The sole source of supply of the apparatus(COA Oil&Grease Analyzer andaccessories)known to the committee at this time is CYCP Oil Analyzers,LLC.,7Beths Rd,Shrewsbury,MA01545,www.cycp-.If you are aware ofalternative suppliers,please provide this information to ASTM InternationalHeadquarters.Your comments will receive careful consideration at a meeting of theresponsible technical committee,1which you may attend.3For 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.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.Terminology3.1 Definitions:3.1.1 burn,vtin emission spectroscopy,to vaporize andexcite a specimen with sufficient energy to generate spectralradiation.3.1.2 cali
