Designation:D 5533 98e1An American National StandardStandard Test Method forEvaluation of Automotive Engine Oils in the Sequence IIIE,Spark-Ignition Engine1This standard is issued under the fixed designation D 5533;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.e1NOTEFigure 15 was deleted and Figs.14 and 17 were corrected editorially in March 1999.INTRODUCTIONThe test method described in this standard can be used by any properly equipped laboratory,withoutthe assistance of anyone not associated with that laboratory.However,the ASTM Test MonitoringCenter(TMC)2provides reference oils and an assessment of the test results obtained on those oils bythe laboratory(see Annex A1).By this means,the laboratory will know whether their use of the testmethod gives results statistically similar to those obtained by other laboratories.Furthermore,variousagencies require that a laboratory utilize the TMC services in seeking qualification of oils againstspecifications.For example,the U.S.Army imposes such a requirement,in connection with severalArmy engine lubricating oil specifications.Accordingly,this test method is written for use by laboratories which utilize the TMC services.Laboratories which choose not to use those services may simply ignore those portions of the testmethod which refer to the TMC.This test method may be modified by means of Information Letters issued by the TMC.In addition,the TMC may issue supplementary memoranda related to the test method(see Annex A1).Users ofthis test method shall contact the ASTM Test Monitoring Center to obtain the most recent of these.1.Scope1.1 This test method covers an engine test procedure forevaluating automotive engine oils for certain high-temperatureperformance characteristics,including oil thickening,sludgeand varnish deposition,and oil consumption,as well as enginewear.Such oils include both single viscosity grade andmultiviscosity grade oils which are used in both spark-ignition,gasoline-fueled engines,as well as in diesel engines.2NOTE1Companion test methods used to evaluate engine oil perfor-mance for specification requirements are discussed in SAE J304.1.2 The values stated in either acceptable SI units or in otherunits shall be regarded separately as standard.The values statedin each system may not be exact equivalents;therefore,eachsystem must be used independently of the other,withoutcombining values in any way.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.4 This test method is arranged as follows:SubjectSectionIntroductionScope1Referenced Documents2Terminology3Summary of Test Method4Significance and Use5Apparatus6Laboratory6.1Drawings6.2Specified Equipment6.3Test Engine6.4Engine Parts6.4.1Hold-Back Fixture6.4.2Engine Speed and Load Control6.5Engine Cooling System6.6Flushing Tank6.7Coolant Mixing Tank6.8Jacketed Rocker Cover,Intake Manifold Crossover,andBreather Tube Cooling Systems6.9External Oil-Cooling System6.10Fuel System6.111This test method is under the jurisdiction of ASTM Committee D-2 onPetroleum Products and Lubricants and is the direct responsibility of SubcommitteeD02.B0.01 on Passenger Car Engine Oils.The multi-cylinder engine test sequences were originally developed in 1956 byanASTM Committee D-2 group.Subsequently,the procedures were published in anASTM special technical publication.The Sequence IIIE method was published asResearch Report RR:D02-1225,dated April 1,1988.Current edition approved Dec.10,1998.Published February 1999.Originallypublished as D 5533 97a.Last previous edition D 5533 96.2ASTM Test Monitoring Center,6555 Penn Ave.,Pittsburgh,PA 15206-4489.For other information,refer to Research Report RR:D02-1225 Multicylinder TestSequences for Evaluating Automotive Engine OilsPart 2 Sequence IIIE.Thisresearch report and this test method are supplemented by Information Letters andmemoranda issued by the ASTM Test Monitoring Center.This edition incorporatesrevisions in all information letters through No.981.1Copyright ASTM,100 Barr Harbor Drive,West Conshohocken,PA 19428-2959,United States.NOTICE:This standard has either been superceded and replaced by a new version or discontinued.Contact ASTM International(www.astm.org)for the latest information.SubjectSectionCarburetor Air Supply Humidity,Temperature,and Pressure6.12Temperature Measurement6.13Thermocouple Location6.13.1Air-to-Fuel Ratio Determination6.14Exhaust and Exhaust Back Pressure Systems6.15Blowby Flow Rate Measurement6.16Pressure Measurement and Pressure Sensor Location6.17Reagents and Materials7Test Fu
