1、Designation: D8074 16Standard Test Method forEvaluation of Diesel Engine Oils in DD13 Diesel Engine1This standard is issued under the fixed designation D8074; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisio
2、n. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONPortions of this test method are written for use by laboratories that make use of ASTM TestMonitoring Center (TMC)2services (see A
3、nnex A1).The TMC provides reference oils, and engineering and statistical services to laboratories that desireto produce test results that are statistically similar to those produced by laboratories previouslycalibrated by the TMC.In general, the Test Purchaser decides if a calibrated test stand is
4、to be used. Organizations such astheAmerican Chemistry Council require that a laboratory utilize the TMC services as part of their testregistration process. In addition, the American Petroleum Institute and the Gear Lubricant ReviewCommittee of the Lubricant Review Institute (SAE International) requ
5、ire that a laboratory use theTMC services in seeking qualification of oils against their specifications.The advantage of using the TMC services to calibrate test stands is that the test laboratory (andhence the Test Purchaser) has an assurance that the test stand was operating at the proper level of
6、 testseverity. It should also be borne in mind that results obtained in a non-calibrated test stand may notbe the same as those obtained in a test stand participating in the ASTM TMC services process.Laboratories that choose not to use the TMC services may simply disregard these portions.1. Scope1.1
7、 This test method covers an engine test procedure forevaluating diesel engine oils for performance characteristics,including adhesive wear between an uncoated piston ring andcylinder liner. This test method is commonly referred to as theDD13 Scuffing Test.1.2 The values stated in SI units are to be
8、regarded asstandard. No other units of measurement are included in thisstandard.1.2.1 ExceptionWhere there is no direct SI equivalent,such as the units for screw threads, National Pipe Threads/diameters, tubing size, and single source supply equipmentspecifications.1.3 This standard does not purport
9、 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 applica-bility of regulatory limitations prior to use. See Annex A2 forspecific safety precautions.2. R
