Designation:D741717Standard Test Method forAnalysis of In-Service Lubricants Using Particular Four-PartIntegrated Tester(Atomic Emission Spectroscopy,InfraredSpectroscopy,Viscosity,and Laser Particle Counter)1This standard is issued under the fixed designation D7417;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 test method covers the quantitative analysis ofin-service lubricants using an automatic testing device thatintegrates these varied technologies:atomic emissionspectroscopy,infrared spectroscopy,viscosity,and particlecounting.1.2 This is suited for in-service lubricating oils havingviscosities in the range between ISO 10 and ISO 320 andproperties in the ranges given in Tables 1 and 2.1.3 This test method may be used to establish trends in wearand contamination of in-service lubricants and may not giveequivalent numerical results to current ASTM test methods.1.4 This test method is not intended for use with crude oil.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.(Specific hazard statements are given in Section 9 and 11.3.)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:2D445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D2270 Practice for Calculating Viscosity Index from Kine-matic Viscosity at 40 C and 100 CD2896 Test Method for Base Number of Petroleum Productsby Potentiometric Perchloric Acid TitrationD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4739 Test Method for Base Number Determination byPotentiometric Hydrochloric Acid TitrationD6595 Test Method for Determination of Wear Metals andContaminants in Used Lubricating Oils or Used HydraulicFluids by Rotating Disc ElectrodeAtomic Emission Spec-trometryD7042 Test Method for Dynamic Viscosity and Density ofLiquids by Stabinger Viscometer(and the Calculation ofKinematic Viscosity)E2412 Practice for Condition Monitoring of In-Service Lu-bricants by Trend Analysis Using Fourier TransformInfrared(FT-IR)Spectrometry2.2 ISO Standards:3ISO 4406:99 Hydraulic Fluid Power Solid ContaminationsCodeISO 11171 Automatic Particle Counter Calibration Proce-dures3.Terminology3.1 Definitions:1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.96.07 on Integrated Testers,Instrumentation Techniques forIn-Service Lubricants.Current edition approved Oct.1,2017.Published October 2017.Originallyapproved in 2010.Last previous edition approved in 2010 as D7417 10.DOI:10.1520/D7417-17.2For 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 from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.*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 3.1.1 electrode,nin an integrated tester,set of two(upperand lower)used in excitation of wear metals during emissionspectroscopic testing.3.1.2 emission spectrometer,ncomponent used to reportelements in parts per million in lubricants.This processmeasures 20 different wear/additive metals that can be presentin the used lubricant after the oil has been in service for aperiod of time.Test Method D6595 can be used for referenceor definition.3.1.3 infrared spectrometer,ncomponent used to reportcondition and contamination of the lubricant(for example,water,oxidation,fuel dilution(gasoline and diesel),nitration,glycol,soot,calculated viscosity,and
