2、ear oforiginal adoption 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.INTRODUCTIONAny properly equipped laboratory, without outside as

3、sistance, can use the test procedure describedin this test method. The ASTM Test Monitoring Center (TMC)2provides calibration oils and anassessment of the test results obtained on those oils by the laboratory. By this means, the laboratorywill know whether their use of the test method gives results

4、statistically similar to those obtained byother laboratories. Furthermore, various agencies require that a laboratory utilize the TMC services inseeking qualification of oils against specifications. For example, the U.S.Army has such a requirementin some of its engine oil specifications. Accordingly

5、, this test method is written for those laboratoriesthat use the TMC services. Laboratories that choose not to use these services should ignore thoseportions of the test method that refer to the TMC. Information Letters issued periodically by the TMCmay modify this test method.3In addition, the TMC

6、may issue supplementary memoranda related tothe test method.1. Scope1.1 This test method covers stressing an engine oil undermodern high-speed diesel operating conditions and measuresthe oils deposit control, lubrication ability, and resistance tooil consumption. It is performed in a laboratory usin

7、g astandardized high-speed, single-cylinder diesel engine.41.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is ther

8、esponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use. Being an enginetest method, this test method does have definite hazards thatrequire safe practices (see Appendix X2 on Safety).1.
