3、bed inthis test method.However,the ASTM Test Monitoring Center(TMC)2provides reference oils and anassessment of the test results obtained on those oils by the laboratory.By these means,the laboratorywill know whether their use of the test method gives results statistically similar to those obtained
4、byother laboratories.Furthermore,various agencies require that a laboratory utilize the TMC services inseeking qualification of oils against specifications.For example,the U.S.Army imposes such arequirement in connection with several Army engine lubricating oil specifications.Accordingly,this test m
5、ethod is written for use by laboratories that utilize the TMC services.Laboratories that choose not to use those services may simply ignore those portions of the test methodthat refer to the TMC.This test method may be modified by means of information letters issued by the TMC.3In addition,the TMC m

7、eration Test(EOAT).The test is conducted using a specified 7.3 L,direct-injection,turbocharged diesel engine on a dynamometer teststand.This test method was developed as a replacement forTest Method D892 after it was determined that this bench testdid not correlate with oil aeration in actual servic
8、e.The EOATwas first included in API Service Category CG-4 in 1995.NOTE1Companion test methods used to evaluate engine oil perfor-mance for specification requirements are discussed in the latest revision ofSpecification D4485.1.2 The values stated in SI units are to be regarded asstandard.No other un
