1、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
2、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
3、 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 gene
4、ral,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
5、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 th
