Designation:D689413Standard Test Method forEvaluation of Aeration Resistance of Engine Oils in Direct-Injected Turbocharged Automotive Diesel Engine1This standard is issued under the fixed designation D6894;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()indicates an editorial change since the last revision or reapproval.INTRODUCTIONAny properly equipped laboratory,without outside assistance,can use the procedure described inthis test method.However,the ASTM Test Monitoring Center(TMC)2provides reference oils and anassessment of the test results obtained on those oils by the laboratory.By these means,the laboratorywill know whether their use of the test method gives results statistically similar to those obtained byother laboratories.Furthermore,various agencies require that a laboratory utilize the TMC services inseeking qualification of oils against specifications.For example,the U.S.Army imposes such arequirement in connection with several Army engine lubricating oil specifications.Accordingly,this test method is written for use by laboratories that utilize the TMC services.Laboratories that choose not to use those services may simply ignore those portions of the test methodthat refer to the TMC.This test method may be modified by means of information letters issued by the TMC.3In addition,the TMC may issue supplementary memoranda related to the method.For other information,refer tothe research report for this test method.41.Scope*1.1 This test method was designed to evaluate an engineoils resistance to aeration in automotive diesel engine service.It is commonly referred to as the Engine Oil Aeration Test(EOAT).The test is conducted using a specified 7.3 L,direct-injection,turbocharged diesel engine on a dynamometer teststand.This test method was developed as a replacement forTest Method D892 after it was determined that this bench testdid not correlate with oil aeration in actual service.The EOATwas first included in API Service Category CG-4 in 1995.NOTE1Companion test methods used to evaluate engine oil perfor-mance for specification requirements are discussed in the latest revision ofSpecification D4485.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.2.1 ExceptionWhere there is no direct SI equivalent,forexample,screw threads,national pipe threads/diameters,andtubing size.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:SectionScope1Referenced Documents2Terminology3Summary of Test Method4Significance and Use5Apparatus6Reagents and Materials7Preparation of Apparatus8Calibration9Test Procedure10Determination of Test Results111This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.B0.02 on Heavy Duty Engine Oils.Current edition approved May 1,2013.Published May 2013.Originallyapproved in 2003.Last previous edition approved in 2011 as D6894 11.DOI:10.1520/D6894-13.2ASTM Test Monitoring Center(TMC),6555 Penn Avenue,Pittsburgh,PA152006-4489.3Until the next revision of this test method,the ASTM Test Monitoring Centerwill update changes in the test method by means of information letters.Informationletters may be obtained from the ASTM Test Monitoring Center(TMC),6555 PennAvenue,Pittsburgh,PA 152006-4489.Attention:Administrator.www.astmtmc.cm-u.edu.This edition incorporates revisions contained in all information lettersthrough 12-1.4Supporting data have been filed at ASTM International Headquarters and maybe obtained by requesting Research Report RR:D02-1379.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Report12Precision and Bias13Keywords14Engine System DrawingsAnnex A12.Referenced Documents2.1 ASTM Standards:5D86 Test Method for Distillation of Petroleum Products atAtmospheric PressureD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD97 Test Method for Pour Point of Petroleum ProductsD130 Test Method for Corrosiveness to Copper from Petro-leum Products by Copper Strip TestD287 Test Method for API Gravity of Crude Petroleum andPetroleum Products(Hydrometer Method)D445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D482 Test Method for Ash from Petroleum ProductsD524 Test Method for Ramsbottom Carbon Residue ofPetroleum ProductsD613 Test Method for Cetane Number of Diesel Fuel
