1、Designation: D7320 16aD7320 17Standard Test Method forEvaluation of Automotive Engine Oils in the Sequence IIIG,Spark-Ignition Engine1This standard is issued under the fixed designation D7320; 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.INTRODUCTIONPortions of this test method are written for use by laboratories that make use of ASTM TestMonit

3、oring Center (TMC)2 services (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 Purc

4、haser 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 and the Gear Lubricant ReviewCommittee of the Lubrica

5、nt 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 (andhence the Test Purchaser) has an assurance that the tes

6、t 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.Laboratories that choose not to use the TMC services may

7、 simply disregard these portions.1. Scope*1.1 This test method covers an engine test procedure for evaluating automotive engine oils for certain high-temperatureperformance characteristics, including oil thickening, varnish deposition, oil consumption, as well as engine wear. Such oilsinclude both s

8、ingle viscosity grade and multiviscosity grade oils that are used in both spark-ignition, gasoline-fueled engines, aswell as in diesel engines.1.1.1 Additionally, with nonmandatory supplemental requirements, a IIIGA Test (Mini Rotary Viscometer and Cold CrankingSimulator measurements), a IIIGVS Test

9、 (EOT viscosity increase measurement), or a IIIGB Test (phosphorous retentionmeasurement) can be conducted. These supplemental test procedures are contained in Appendixes Appendix X1, Appendix X2,and Appendix X3, respectively.NOTE 1Companion test methods used to evaluate engine oil performance for s
