1、Designation: D 7320 07An American National StandardStandard Test Method forEvaluation of Automotive Engine Oils in the Sequence IIIG,Spark-Ignition Engine1This standard is issued under the fixed designation D 7320; the number immediately following the designation indicates the year oforiginal adopti

2、on or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe test method described in this standard can be used by any properly eq

3、uipped laboratory; it doesnot require the assistance of anyone outside that laboratory. However, the ASTM Test MonitoringCenter (TMC)2provides reference oils and an assessment of the test results obtained on those oils bythe laboratory (see Annex A1). By these means, the laboratory will know whether

4、 their use of the testmethod gives results statistically similar to those obtained by other laboratories. Furthermore, variousagencies require that a laboratory utilize the TMC services in seeking qualification of oils againstspecifications. For example, the U.S. Army imposes such a requirement in c

5、onnection with severalArmy engine lubricating oil specifications.Accordingly, this test method 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

6、 may be modified by means of Information Letters issued by the TMC. In addition,the TMC may issue supplementary memoranda related to the test method (see A1.8).1. Scope1.1 This test method covers an engine test procedure forevaluating automotive engine oils for certain high-temperatureperformance ch

7、aracteristics, including oil thickening, varnishdeposition, oil consumption, as well as engine wear. Such oilsinclude both single viscosity grade and multiviscosity gradeoils that are used in both spark-ignition, gasoline-fueledengines, as well as in diesel engines.NOTE 1Companion test methods used

8、to evaluate engine oil perfor-mance for specification requirements are discussed in SAE J304.1.2 The values stated in SI units shall be regarded as thestandard. The values given in parentheses are provided forinformation purposes only. The only exception is where thereis no direct SI equivalent such

9、 as screw threads, national pipethreads/diameters, and tubing size.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the ap

10、plica-bility of regulatory limitations prior to use.
