Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis test method can be used by an
3、y properly equipped laboratory without outside assistance.However, the ASTM Test Monitoring Center (TMC)3 provides reference oils and assessment of thetest results obtained on those oils by the laboratory (see AnnexA1). By this means, the laboratory willknow whether their use of this test method giv
4、es results statistically similar to those obtained by otherlaboratories. Furthermore, various agencies require that a laboratory utilize the TMC services inseeking qualification of oils against specifications. For example, the American Petroleum Institute(API) imposes such a requirement, in connecti
5、on with several U.S. Army engine lubricating oilspecifications. Accordingly, this test method is written for use by laboratories that utilize the TMCservices. Laboratories that choose not to use those services may simply ignore those portions of thistest method that refer to the TMC. This test metho
6、d may be modified by means of Information Lettersissued by the TMC. In addition, the TMC may issue supplementary memoranda related to this testmethod. Users of this test method shall contact the TMC, Attention: Administrator, to obtain the mostrecent of these information letters.1. Scope*1.1 This te
7、st 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 weight 3856 kg or less. The tests are conducted using aspecified spark-ignition engine with a displacement of 3.6 L (Ge
8、neral Motors)4 on a dynamometer test stand. It applies to multiviscosity grade oils used in these applications.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.2.1 ExceptionsWhere there is no direct equivalent such as the
9、 units for screw threads, National Pipe threads/diameters,tubing size, and single source supply equipment specifications. Additionally, Brake Fuel Consumption (BSFC) is measured inkilograms per kilowatthour.1.3 This standard does not purport to address all of the safety concerns, if any, associated
10、with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.1.4 This test method is arranged as follows:Subject SectionIntroductionScope 1Referenced Documents 21 This tes
