4、nter.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 laboratory will know whether
5、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 such a requirement,in co
6、nnection 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. Scope*1.1 This en
7、gine lubricant test method is commonly referred to as the Roller Follower Wear Test. Its primary result, rollerfollower shaft wear in the hydraulic valve lifter assembly, has been correlated with vehicles used in stop-and-go delivery serviceprior to 1993. It is one of the test methods required to ev
8、aluate lubricants intended to satisfy the API CG-4 performance category.This test has also been referred to as the 6.2 L Test.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.2.1 ExceptionsWhere there is no direct SI equi
9、valent, such as pipe fittings, thermocouple diameters, and NPT screw threads.Also, roller follower wear is measured in mils.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

Summary of Test Method4.1 A pre-assembled GM V8 diesel test engine is installed on a test stand and operated for 50 h.4 Available from American National Sta
37、ndards Institute (ANSI), 25 W. 43rd St., 4th Floor, New York, NY 10036.D5966 1334.2 The test engine operating conditions are generally more extreme than typical service operating conditions. These conditionsprovide high soot loading and accelerated roller follower shaft wear while maintaining correl
38、ation with wear levels found in thefield.4.3 At the end of the test, the performance of the engine oil is determined by measuring the level of wear on the roller followershafts.5. Significance and Use5.1 This test method is used to determine the ability of an engine crankcase oil to control wear tha
39、t can develop in the field underlow to moderate engine speeds and heavy engine torques. Side-by-side comparisons of two or more oils in delivery van fleets wereused to demonstrate the field performance of various oils. The specific operating conditions of this test method were developedto provide co
40、rrelation with the field performance of these oils.5.2 This test method, along with other test methods, defines the minimum performance level of the Category API CG-4 forheavy duty diesel engine lubricants. Passing limits for this category are included in Specification D4485.5.3 The design of the en
41、gine used in this test method is not representative of all modern diesel engines. Consider this factor,along with the specific operating conditions used to accelerate wear, when extrapolating test results.6.
