1、Designation: D 5966 09Standard Test Method forEvaluation of Engine Oils for Roller Follower Wear in Light-Duty Diesel Engine1This standard is issued under the fixed designation D 5966; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision

2、, 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.INTRODUCTIONThis test method is continually undergoing changes to reflect refinements in procedure, obsoles-cence of

3、 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 the ASTM TestMonitoring Center.2

4、The 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 laboratory will know whether theiru

5、se 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 such a requirement,in connecti

6、on 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 TMC.1.

7、bricant 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 methods required toevaluate lub

8、ricants 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 stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.2.1 ExceptionsWhere there is no direct SI equivalent,such

9、 as pipe fittings, thermocouple diameters, and NPT screwthreads. Also, roller follower wear is measured in mils.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 saf
