Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONPortions of this test method are written for use
3、by laboratories that make use of ASTM TestMonitoring Center (TMC)3services (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 laboratories previouslyca
4、librated 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 Institute (API) an
5、d the Gear LubricantReview Committee of the Lubricant Review Institute (SAE International) require that a laboratory usethe TMC 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 (andhenc
6、e 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 process.Labor
7、atories that choose not to use the TMC services may simply disregard these portions.1. Scope1.1 This test method covers an engine test procedure for themeasurement of the effects of automotive engine oils on thefuel economy of passenger cars and light-duty trucks withgross vehicle weight 3856 kg or
8、less. The tests are conductedusing a specified spark-ignition engine with a displacement of3.6 L (General Motors)4on a dynamometer test stand. Itapplies to multi-viscosity oils used in these applications.1.2 The values stated in SI units are to be regarded asstandard. No other units of measurement a
