3、ring Center (TMC)2 services (see Annex 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 deci
4、des 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 Institute and the Gear Lubricant ReviewCommittee of the Lubricant Review
5、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 laboratory (andhence the test purchaser) has an assurance that the test stand wa
6、s 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 process.1. Scope Scope*1.1 This test method covers an engine test procedur
7、e for evaluating automotive engine oils for certain high-temperatureperformance characteristics, including oil thickening (as measured by kinematic viscosity increase), piston deposits, ring sticking,oil consumption, and phosphorus retention. Such oils include both single-viscosity and multiviscosit
8、y grade oils that are used inboth spark-ignition, gasoline-fueled engines, as well as in diesel engines.1.1.1 Additionally, with nonmandatory supplemental requirements, a Sequence IIIHA Test (Mini Rotary Viscometer and ColdCranking Simulator measurements), or a Sequence IIIHB Test (phosphorus retent
9、ion measurement) can be conducted. Thesesupplemental test procedures are contained in Appendix X1 and Appendix X2, respectively.NOTE 1Companion test methods used to evaluate engine oil performance for specification requirements are discussed in SAE J304.1.2 The values stated in SI units are to be re
