3、in procedure, obsoles-cence of parts or reagents. 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 th
4、e ASTM TestMonitoring Center.2The test method can 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 labor
5、atory will know whether theiruse of the test method 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
6、such a requirement,in connection with several military lubricant 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
7、TMC.1. Scope1.1 This engine lubricant test method is commonly 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 1993.3It is one of the test m
8、ethods required toevaluate lubricants intended to satisfy the API CG-4 perfor-mance category. This test has also been referred to as the 6.2 LTest.1.2 The values of units used in this test method are stated ineither inch-pound units or SI units and are to be regardedseparately as the standard.1.3 Th
9、is 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 and health practices and determine the applica-bility of regulatory limitations prior to use.1.4 Table of Contents

Summary of Test Method4.1 A pre-assembled GM V8 diesel test engine is installedon a test stand and operated for 50 h.4.2 The test engine operating conditions are generally moreextreme than typical service operating conditions. These con-ditions provide high soot loading and accelerated roller f
38、ol-lower shaft wear while maintaining correlation with wearlevels found in the field.34.3 At the end of the test, the performance of the engine oilis determined by measuring the level of wear on the rollerfollower shafts.5. Significance and Use5.1 This test method is used to determine the ability of
39、 anengine crankcase oil to control wear that can develop in thefield under low to moderate engine speeds and heavy engineloads. Side-by-side comparisons of two or more oils in deliveryvan fleets were used to demonstrate the field performance ofvarious oils.3The specific operating conditions of this
40、testmethod were developed to provide correlation with the fieldperformance of these oils.5.2 This test method, along with other test methods, definesthe minimum performance level of the Category API CG-4 forheavy duty diesel engine lubricants. Passing limits for thiscategory are included in Specific
41、ation D 4485.5.3 The design of the engine used in this test method is notrepresentative of all modern diesel engines. This factor, alongwith the specific operating conditions used to accelerate wear,shall be considered when extrapolating test results.6. Apparatus6.1 A listing and complete descriptio
