Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONPortions of this test method are wr
3、itten for use by laboratories that make use of ASTM TestMonitoring Center (TMC)2 services (see Annex A1 Annex A4).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 laborator
4、ies previouslycalibrated by the TMC.In general, the Test Purchaser decides if a calibrated test stand is 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 In
5、stitute and the Gear Lubricant ReviewCommittee of the Lubricant Review Institute (SAE International) require 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 laborator
6、y (andhence the Test Purchaser) has an assurance that the test stand was operating at the proper level of 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 pro
7、cess.Laboratories that choose not to use the TMC services may simply disregard these portions.1. Scope*1.1 These test methods cover the performance of engine oils intended for use in certain diesel engines. They are performed ina standardized high-speed, single-cylinder diesel engine by either the 1
8、K (0.4 % mass fuel sulfur) or 1N (0.04 % mass fuel sulfur)procedure.3 The only difference in the two test methods is the fuel used. Piston and ring groove deposit-forming tendency and oilconsumption are measured.Also, the piston, the rings, and the liner are examined for distress and the rings for m
9、obility. These testmethods are required to evaluate oils intended to satisfy API service categories CF-4 and CH-4 for 1K, and CG-4 for 1N ofSpecification D4485.1.2 These test methods, although based on the original Caterpillar 1K/1N procedures,3 also embody TMC information lettersissued before these
10、 test methods were first published. These test methods are subject to frequent change. Until the next revisionof these test methods, TMC will update changes in these test methods by the issuance of information letters which shall be obtainedfrom TMC (see Annex A1 Annex A4).1.3 The values stated in S
11、I units are to be regarded as standard. No other units of measurement are included in this standard.1.3.1 ExceptionWhere there is no direct SI equivalent such as screw threads, national pipe threads/diameters, tubing size, orsingle source equipment specified. Also Brake Specific Fuel Consumption is
