Designation:D8034/D8034M17Standard Test Method forSimulated Service Corrosion Testing of Non-AqueousEngine Coolants1This standard is issued under the fixed designation D8034/D8034M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method evaluates the effect of a circulatingengine coolant on metal test specimens and automotive coolingsystem components under controlled,essentially isothermallaboratory conditions.1.2 This test method specifies test material,cooling systemcomponents,type of coolant,and coolant flow conditions thatare considered typical of current automotive use.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.Some values have only SI units because theinch-pound equivalents are not used in practice.1.4 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.Specific precau-tionary statements are given in Section 6.1.5 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:2D1121 Test Method for Reserve Alkalinity of Engine Cool-ants and AntirustsD1123 Test Methods for Water in Engine Coolant Concen-trate by the Karl Fischer Reagent MethodD1176 Practice for Sampling and Preparing Aqueous Solu-tions of Engine Coolants orAntirusts for Testing PurposesD1193 Specification for Reagent WaterD1287 Test Method for pH of Engine Coolants andAntirustsD2570 Test Method for Simulated Service Corrosion Testingof Engine CoolantsD7935/D7935M Test Method for Corrosion Test for Non-Aqueous Engine Coolants in GlasswareE203 Test Method for Water Using Volumetric Karl FischerTitration2.2 SAE Standard:3SAE J20e Standard for Coolant System Hoses2.3 ASTM Adjuncts:Coolant reservoir(1 drawing)4Framework for test equipment(3 drawings and B/M)53.Summary of Test Method3.1 An engine coolant is circulated for 1064 h at 96.1 C205 F in a flow loop consisting of a metal reservoir,anautomotive coolant pump,an automotive radiator,and connect-ing rubber hoses.Test specimens representative of enginecooling system metals are mounted inside the reservoir,whichsimulates an engine cylinder block.At the end of the testperiod,the corrosion-inhibiting properties of the coolant aredetermined by measuring the mass losses of the test specimens,and by visual examination of the interior surfaces of thecomponents.4.Significance and Use4.1 This test method,by a closer approach to engine coolingsystem conditions,provides better evaluation and selectivescreening of engine coolants than is possible from glassware1This test method is under the jurisdiction of ASTM Committee D15 on EngineCoolants and Related Fluids and is the direct responsibility of SubcommitteeD15.22 on Non-Aqueous Coolants.Current edition approved April 1,2017.Published April 2017.Originallyapproved in 2016.Last previous edition approved in 2016 as D8034/D8034M-16.DOI:10.1520/D8034_D8034M-17.2For 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.3Available from SAE International(SAE),400 Commonwealth Dr.,Warrendale,PA 15096,http:/www.sae.org.4Detail drawings are available from ASTM International Headquarters.OrderAdjunct No.ADJD257001.Original adjunct produced in 1982.Reservoirs of castiron or cast aluminum,made in accordance with these drawings may be obtainedfrom Commercial Machine Service,1099 TouhyAve.,Elk Grove Village,IL 60007.5Detail and assembly drawings of a suitable framework and arrangement ofcomponents thereon are available from ASTM International Headquarters.OrderAdjunct No.ADJD257002.Original adjunct produced in 1982.*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
