3、RODUCTIONThe test method described in this standard can be used by any properly equipped laboratory,withoutthe assistance of anyone not associated with that laboratory.However,the ASTM Test MonitoringCenter(TMC)2provides reference oils and an assessment of the test results obtained on those oils byt
4、he laboratory(see Annex A1).By this means,the laboratory will know whether 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 againstsp
5、ecifications.For example,the U.S.Army imposes such a requirement,in connection with severalArmy engine lubricating oil specifications.Accordingly,this test method is written for use by laboratories which utilize the TMC services.Laboratories which choose not to use those services may simply ignore t
6、hose portions of the testmethod which refer to the TMC.This test method 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 Annex A1).Users ofthis test method shall contact the ASTM Test Monitoring Cen

8、clude both single viscosity grade andmultiviscosity grade oils which are used in both spark-ignition,gasoline-fueled engines,as well as in diesel engines.2NOTE1Companion test methods used to evaluate engine oil perfor-mance for specification requirements are discussed in SAE J304.1.2 The values stat
9、ed in either acceptable SI units or in otherunits shall be regarded separately as standard.The values statedin each system may not be exact equivalents;therefore,eachsystem must be used independently of the other,withoutcombining values in any way.1.3 This standard does not purport to address all of
10、 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 applica-bility of regulatory limitations prior to use.1.4 This test method is arranged as follows:SubjectSectionIntroduction
