1、Designation:D754915aStandard Test Method forEvaluation of Heavy-Duty Engine Oils under High OutputConditionsCaterpillar C13 Test Procedure1This standard is issued under the fixed designation D7549;the number immediately following the designation indicates the year oforiginal adoption or,in the case
2、of 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.INTRODUCTIONAny properly equipped laboratory,without outside assistance,can use the test procedure describedin
3、 this test method.The ASTM Test Monitoring Center(TMC)2provides calibration and anassessment of the test results obtained on those oils by the laboratory.By this means the laboratorywill know whether its use of the test method gives results statistically similar to those obtained byother laboratorie
4、s.Furthermore,various agencies require that a laboratory utilizes the TMC servicesin seeking qualification of oils against specifications.For example,the U.S.Army has such arequirement in some of its engine oil specifications.Accordingly,this test method is written for thoselaboratories that use the
5、 TMC services.Laboratories that choose not to use these services shouldignore those portions of the test method that refer to the TMC.Information letters2issued periodicallyby the TMC may modify this test method.In addition the TMC may issue supplementary memorandarelated to the test method.1.Scope*
6、1.1 The test method covers a heavy-duty engine test proce-dure under high output conditions to evaluate engine oilperformance with regard to piston deposit formation,pistonring sticking and oil consumption control in a combustionenvironment designed to minimize exhaust emissions.This testmethod is c
