1、Designation: D6984 15D6984 15aStandard Test Method forEvaluation of Automotive Engine Oils in the Sequence IIIF,Spark-Ignition Engine1This standard is issued under the fixed designation D6984; the number immediately following the designation indicates the year oforiginal adoption or, in the case of
2、revision, 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 Portions of this test method described can be used by any properly equipped laboratory; it
3、doesnot require the assistance of anyone outside that laboratory. However, theare written for use bylaboratories that make use of ASTM Test Monitoring Center (TMC)2 provides reference oils and anassessment of the test results obtained on those oils by the laboratory services (see Annex A1). Bythese
4、means, the laboratory will know whether their use of the test method gives results statisticallysimilar to those obtained by other laboratories. Furthermore, various agencies require that a laboratoryutilize the TMC services in seeking qualification of oils against specifications. For example, the U
5、.S.Army imposes such a requirement in connection with several Army engine lubricating oilspecifications.The TMC provides reference oils, and engineering and statistical services to laboratories that desireto produce test results that are statistically similar to those produced by laboratories previo
6、uslycalibrated by the TMC.In general, the Test Purchaser decides if a calibrated test stand is to be used. Organizations such astheAmerican Chemistry Council require that a laboratory utilize the TMC services as part of their testregistration process. In addition, the American Petroleum Institute an
7、d the Gear Lubricant ReviewCommittee of the Lubricant Review Institute (SAE International) require that a laboratory use theTMC services in seeking qualification of oils against their specifications.The advantage of using the TMC services to calibrate test stands is that the test laboratory (andhenc
8、e the Test Purchaser) has an assurance that the test stand was operating at the proper level of testseverity. It should also be borne in mind that results obtained in a non-calibrated test stand may notbe the same as those obtained in a test stand participating in the ASTM TMC services process.Accor
9、dingly, this test method is written for use by laboratories that utilize the TMC services.Laboratories that choose not to use those the TMC services may simply ignore those portions of thetest method that refer to the TMC.disregard these portions.This test method may be modified by means of Informat
10、ion Letters issued by the TMC. In addition,the TMC may issue supplementary memoranda related to the test method (see A1.8).1. Scope*1.1 This test method covers an engine test procedure for evaluating automotive engine oils for certain high-temperatureperformance characteristics, including oil thicke
11、ning, varnish deposition, oil consumption, as well as engine wear. Such oilsinclude both single viscosity grade and multiviscosity grade oils that are used in both spark-ignition, gasoline-fueled engines, aswell as in diesel engines.NOTE 1Companion test methods used to evaluate engine oil performanc
12、e for specification requirements are discussed in SAE J304.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1 This test method is under the jurisdiction ofASTM Committee D02 on Petroleum Products, Liquid Fuels, and Lubrican
