1、Designation: D6984 16aStandard 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 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.INTRODUCTIONPortions of this test method are written for use by laboratories that make use of ASTM TestMonitoring Ce
3、nter (TMC)2services (see Annex A1 Annex A4).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 previouslycalibrated by the TMC.In general, the Test Purchaser dec
4、ides 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 and the Gear Lubricant ReviewCommittee of the Lubricant Review
5、 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 (andhence the Test Purchaser) has an assurance that the test stand w

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.Laboratories that choose not to use the TMC services may simply d
7、isregard these portions.1. Scope*1.1 This test method covers an engine test procedure forevaluating automotive engine oils for certain high-temperatureperformance characteristics, including oil thickening, varnishdeposition, oil consumption, as well as engine wear. Such oilsinclude both single visco
