Designation:D584607(Reapproved 2017)Standard Test Method forUniversal Oxidation Test for Hydraulic and Turbine OilsUsing the Universal Oxidation Test Apparatus1This standard is issued under the fixed designation D5846;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 a procedure for evaluating theoxidation stability of petroleum base hydraulic oils and oils forsteam and gas turbines.1.2 This test method was developed to evaluate the oxida-tion stability of petroleum base hydraulic oils and oils forsteam and gas turbines.1.2.1 Rust and oxidation inhibited hydraulic,anti-wear hy-draulic and turbine oils of ISO 3268 viscosity were used todevelop the precision statement.This test method has beenused to evaluate the oxidation stability of fluids made withsynthetic basestock and in-service oils;however,these fluidshave not been used in cooperative testing to develop precisiondata.1.3 The values stated in SI units are to be regarded asstandard.1.3.1 ExceptionThe values given in parentheses are forinformation only.1.4 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.Identified hazardous chemicals are listed in 7.3,7.6,and 7.8.Before using this test method,refer to suppliers safety labels,Material Safety Data Sheets,and other technical literature.1.5 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:2A510 Specification for General Requirements for Wire Rodsand Coarse Round Wire,Carbon SteelB1 Specification for Hard-Drawn Copper WireD664 Test Method for Acid Number of Petroleum Productsby Potentiometric TitrationD943 Test Method for Oxidation Characteristics of InhibitedMineral OilsD974 Test Method for Acid and Base Number by Color-Indicator TitrationD3339 Test Method forAcid Number of Petroleum Productsby Semi-Micro Color Indicator TitrationD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4740 Test Method for Cleanliness and Compatibility ofResidual Fuels by Spot TestD4871 Guide for Universal Oxidation/Thermal StabilityTest ApparatusD5770 Test Method for Semiquantitative Micro Determina-tion of Acid Number of Lubricating Oils During Oxida-tion Testing2.2 Energy Institute Standard:3IP 2546Practice for Sampling of Petroleum Products;alternate to Practice D40572.3 British Standard:4BS 1829 Specification for Carbon Steel Wire;alternate toSpecification A5102.4 ASTM Adjuncts:Reference Spot Sheet53.Terminology3.1 Definitions of Terms Specific to This Standard:1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.09.0D on Oxidation of Lubricants.Current edition approved Oct.1,2017.Published November 2017.Originallyapproved in 1995.Last previous edition approved in 2012 as D584607(2012).DOI:10.1520/D5846-07R17.2For 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 Energy Institute,61 New Cavendish St.,London,WIG 7AR,U.K.,http:/www.energyinst.org.uk.4Available from British Standards Institute(BSI),389 Chiswick High Rd.,London W4 4AL,U.K.,http:/www.bsi-.5Available from ASTM International Headquarters.Order Adjunct No.ADJD4740.Original adjunct produced in 2000.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.1 3.1.1 inhibited mineral oil,na petroleum oil containingadditives to retard oxidation.3.1.2 oxidation life,nof an oil,the time in hours requiredfor degradation of the oil under test.3.1.3 universal oxidation test,nthe apparatus and proce-dures described in Guide D4871.4.Summary of Test Method4.1 An oil sample is contacted with air at 135 C in thepresence of copper and iron metals.The acid number and spotforming tendency of
