Designation:D570422Standard Test Method forEvaluation of the Thermal and Oxidative Stability ofLubricating Oils Used for Manual Transmissions and FinalDrive Axles1This standard is issued under the fixed designation D5704;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.INTRODUCTIONPortions of this test method are written for use by laboratories that make use of ASTM TestMonitoring Center(TMC)2services(see Annex A1 Annex A4).The TMC provides reference oils,and engineering and statistical services to laboratories that desireto produce test results that are statistically similar to those produced by laboratories previouslycalibrated by the TMC.In general,the Test Purchaser decides if a calibrated test stand is to be used.Organizations such astheAmerican Chemistry Council require that a laboratory utilize the TMC services as part of their testregistration process.In addition,the American Petroleum Institute and the Gear Lubricant ReviewCommittee of the Lubricant Review Institute(SAE International)require that a laboratory use theTMC services in seeking qualification of oils against their specifications.The advantage of using the TMC services to calibrate test stands is that the test laboratory(andhence the Test Purchaser)has an assurance that the test stand was operating at the proper level of testseverity.It should also be borne in mind that results obtained in a non-calibrated test stand may notbe the same as those obtained in a test stand participating in the ASTM TMC services process.Laboratories that choose not to use the TMC services may simply disregard these portions.1.Scope*1.1 This test method is commonly referred to as the L-60-1test.2It covers the oil-thickening,insolubles-formation,anddeposit-formation characteristics of automotive manual trans-mission and final drive axle lubricating oils when subjected tohigh-temperature oxidizing conditions.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.2.1 ExceptionsThe values stated in SI units for catalystmass loss,oil mass and volume,alternator output,and air floware to be regarded as standard.1.2.2 SI units are provided for all parameters except wherethere is no direct equivalent such as the units for screw threads,or where there is a sole source supply equipment specification.1.3 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 warning information is given in Sections 7 and 8 andAnnex A7.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for the1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.B0.03 on Automotive Gear Lubricants&Fluids.Current edition approved April 1,2022.Published April 2022.Originallyapproved in 1995.Last previous edition approved in 2020 as D5704 20.DOI:10.1520/D5704-22.2Until the next revision of this test method,the ASTM Test Monitoring Centerwill update changes in the test method by means of information letters.Informationletters may be obtained from the ASTM Test Monitoring Center,203 ArmstrongDrive,Freeport,PA 16229.Attention:Director.This edition incorporates revisionsin all information Letters through No.22-1.*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.1Development of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:3B224 Classification of CoppersD235 Specification for Mineral Spirits(Petroleum Spirits)(Hydrocarbon Dry Cleaning Solvent)D445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D664 Test Method for Acid Number of Petroleum Productsby Potentiometric TitrationD893 Test Method for Insolubles in Used Lubricating OilsD6984 Test Me
