3、for use by laboratories that make use of ASTM TestMonitoring Center (TMC)3 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 laboratories pre

4、viouslycalibrated 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

5、 (API) and 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

6、 (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 proc

7、ess.Laboratories that choose not to use the TMC services may simply disregard these portions.1. Scope Scope*1.1 This test method covers an engine test procedure for the measurement of the effects of automotive engine oils on the fueleconomy of passenger cars and light-duty trucks with gross vehicle
