Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis test method described can be used by any properly equipped laboratory; it does not require

3、 theassistance of anyone outside that laboratory. However, the ASTM Test Monitoring Center (TMC)2provides reference oils and an assessment of the test results obtained on those oils by the laboratory(see Annex A1). By these means, the laboratory will know whether their use of the test method givesre

Furthermore, various agenciesrequire that a laboratory utilize the TMC services in seeking qualification of oils against specifications.For example, the U.S. Army imposes such a requirement in connection with several Army enginelub

6、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
