1、Designation:D596613Standard Test Method forEvaluation of Engine Oils for Roller Follower Wear in Light-Duty Diesel Engine1This standard is issued under the fixed designation D5966;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the y
2、ear 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.INTRODUCTIONThis test method is continually undergoing changes to reflect refinements in procedure,obsoles-cence of parts or re
3、agents.These changes or updates,as well as general information regarding the testmethod,are issued as information letters by the ASTM Test Monitoring Center(TMC).Copies ofinformation letters pertaining to the test method may be obtained by contacting the ASTM TestMonitoring Center.2The test method c
4、an be used by any properly equipped laboratory,without assistance of anyone notassociated with that laboratory.However,TMC provides reference oils and an assessment of the testresults obtained on those oils by the laboratory.By this means,the laboratory will know whether theiruse of the test method
5、gives results statistically similar to those obtained by other laboratories.Furthermore,various agencies require that a laboratory utilize the TMC services in seekingqualification of oils against specifications.For example,the U.S.Army imposes such a requirement,in connection with several military l
6、ubricant specifications.Accordingly,this test method is written for use by laboratories which utilize the TMC services.Laboratories that choose not to use these services may simply ignore those portions of the testprocedure which refer to the TMC.1.Scope*1.1 This engine lubricant test method is comm
7、only referredto as the Roller Follower Wear Test.Its primary result,rollerfollower shaft wear in the hydraulic valve lifter assembly,hasbeen correlated with vehicles used in stop-and-go deliveryservice prior to 1993.It is one of the test methods required toevaluate lubricants intended to satisfy the
