Designation:D6594201Standard Test Method forEvaluation of Corrosiveness of Diesel Engine Oil at 135 C1This standard is issued under the fixed designation D6594;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.1NOTEEditorially updated TMC governance information in June 2022.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(see AnnexA1).By these means,the laboratory will know whether their use of the test method gives results statistically similar to thoseobtained by other laboratories.Furthermore,various agencies require that a laboratory utilize the TMCservices in seeking qualification of oils against specifications.For example,the U.S.Army imposessuch a requirement 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.In addition,the TMC may issue supplementary memoranda related to the method(see Annex A1).For otherinformation,refer to the research report of this test method.31.Scope*1.1 This test method covers testing diesel engine lubricantsto determine their tendency to corrode various metals,specifi-cally alloys of lead and copper commonly used in camfollowers and bearings.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:4D130 Test Method for Corrosiveness to Copper from Petro-leum Products by Copper Strip TestD5185 Test Method for Multielement Determination ofUsed and Unused Lubricating Oils and Base Oils byInductively Coupled Plasma Atomic Emission Spectrom-etry(ICP-AES)D5844 Test Method for Evaluation of Automotive EngineOils for Inhibition of Rusting(Sequence IID)(Withdrawn2003)5D6557 Test Method for Evaluation of Rust Preventive Char-acteristics of Automotive Engine Oils1This 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 1,2020.Published May 2020.Originallyapproved in 2000.Last previous edition approved in 2019 as D6594 19a.DOI:10.1520/D6594-20E01.2The ASTM Test Monitoring Center will update changes in this test method bymeans of Information Letters.This edition incorporates revisions contained in allInformation Letters through 19-2.Information Letters may be obtained from theASTM Test Monitoring Center,203 Armstrong Drive,Freeport,PA 16229,Attention:Director.3Supporting data have been filed at ASTM International Headquarters and maybe obtained by requesting Research Report RR:D02-1443.ContactASTM CustomerService at serviceastm.org.4For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.5The last approved version of this historical standard is referenced onwww.astm.org.*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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.13.Terminology3.1 Definitions:3.1.1 corrosion,nthe chemical or electrochemical reac-tion between a material,usually a metal surface,and itsenvironment that can produce a deterioration of the materialand its properties.D58443.
