Designation:D751719Standard Specification forFully-Formulated 1,3 Propanediol(PDO)Base EngineCoolant for Heavy-Duty Engines1This standard is issued under the fixed designation D7517;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.1.Scope*1.1 This specification covers the requirements for fully-formulated glycol base coolants for cooling systems of heavy-duty engines.When concentrates are used at 40 to 60%PDOconcentration by volume in water of suitable quality,(seeAppendix X1),or when prediluted PDO base engine coolants(50 volume%minimum)are used without further dilution,they will function effectively during both winter and summer toprovide protection against corrosion,cavitation,freezing,andboiling.1.2 The coolants governed by this specification are catego-rized as follows:Coolant TypeDescriptionI-FF1,3 Propanediol base concentrateII-FF1,3 Propanediol predilute(50 vol%)1.3 Coolant concentrates meeting this specification do notrequire any addition of Supplemental Coolant Additive(SCA)until the first maintenance interval when a maintenance dose ofSCA is required to continue protection in certain heavy-dutyengine cooling systems,particularly those of the wet cylinderliner-in-block design.The SCA additions are defined by andare the primary responsibility of the engine manufacturer orvehicle manufacturer.If they provide no instructions,followthe SCA suppliers instructions.1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses after SI units areprovided for information only and are not considered standard.1.5 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.1.6 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:2D512 Test Methods for Chloride Ion In WaterD516 Test Method for Sulfate Ion in WaterD1126 Test Method for Hardness in WaterD1287 Test Method for pH of Engine Coolants andAntirustsD1293 Test Methods for pH of WaterD4327 Test Method for Anions in Water by Suppressed IonChromatographyD4725 Terminology for Engine Coolants and Related FluidsD5827 Test Method for Analysis of Engine Coolant forChloride and Other Anions by Ion ChromatographyD5828 Test Method for Compatibility of SupplementalCoolant Additives(SCAs)and Engine Coolant Concen-tratesD6130 Test Method for Determination of Silicon and OtherElements in Engine Coolant by Inductively CoupledPlasma-Atomic Emission SpectroscopyD7518 Specification for 1,3 Propanediol(PDO)Base EngineCoolant for Automobile and Light-Duty ServiceD7583 Test Method for John Deere Coolant Cavitation TestE394 Test Method for Iron in Trace Quantities Using the1,10-Phenanthroline Method2.2 Other Document:3Federal Method 2540B Total Dissolved Solids Dried at103-105C1This specification is under the jurisdiction ofASTM Committee D15 on EngineCoolants and Related Fluids and is the direct responsibility of SubcommitteeD15.07 on Specifications.Current edition approved April 1,2019.Published April 2019.Originallyapproved in 2009.Last previous edition approved in 2014 as D751709(2014).DOI:10.1520/D751719.2For 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.3Standard Methods for the Examination of Water and Wastewater.AmericanPublic Health Association,et al,800 I Street,NW,Washington,DC 20001,http:/www.apha.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.1 3.Terminology3.1 Definitions:3.1.1 supplemental coolant additive(SCA),nan additiveused in conventionally inhibited heavy-duty engine coolantsrequired to maintain protection against general corrosion,cylinder liner pitting,and scaling in heavy-duty engines.3.1.2 For other definitions used in this specificati
