Designation:D771411Standard Specification forGlycerin Base Engine Coolant for Automobile and Light-Duty Service1This standard is issued under the fixed designation D7714;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.Scope1.1 This specification covers the requirements for glycerinbase engine coolants used in automobiles or other light dutyservice cooling systems.When concentrates are used at 50 to60%concentration by volume in water,or when predilutedglycerin base engine coolants(50 volume%minimum)areused without further dilution,they will function effectively toprovide protection against freezing,boiling,and corrosion.1.2 The coolants governed by this specification are catego-rized as follows:Coolant TypeDescriptionIGlycerin base concentrateIIGlycerin predilute(50 to 60 volume%)NOTE1This specification is based on the knowledge of the perfor-mance of engine coolants prepared from new or virgin ingredients thatcomply with Specification D7640.1.3 The values stated in SI units are to be regarded as thestandard.The values in parentheses are for information only.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.See X1.5 forspecific caution statement.NOTE2This specification applies to automobiles and light dutyservice.A glycerin based specification for heavy duty engine service isunder development.2.Referenced Documents2.1 ASTM Standards:2D512 Test Methods for Chloride Ion In WaterD516 Test Method for Sulfate Ion in WaterD1119 Test Method for Percent Ash Content of EngineCoolantsD1120 Test Method for Boiling Point of Engine CoolantsD1121 Test Method for Reserve Alkalinity of Engine Cool-ants and AntirustsD1122 Test Method for Density or Relative Density ofEngine Coolant Concentrates and Engine Coolants By TheHydrometerD1123 Test Methods for Water in Engine Coolant Concen-trate by the Karl Fischer Reagent MethodD1126 Test Method for Hardness in WaterD1177 Test Method for Freezing Point of Aqueous EngineCoolantsD1287 Test Method for pH of Engine Coolants andAntirustsD1293 Test Methods for pH of WaterD1384 Test Method for Corrosion Test for Engine Coolantsin GlasswareD1881 Test Method for Foaming Tendencies of EngineCoolants in GlasswareD1882 Test Method for Effect of Cooling System ChemicalSolutions on Organic Finishes for Automotive VehiclesD2570 Test Method for Simulated Service Corrosion Testingof Engine CoolantsD2809 Test Method for Cavitation Corrosion and Erosion-Corrosion Characteristics of Aluminum Pumps With En-gine CoolantsD3321 Test Method for Use of the Refractometer for FieldTest Determination of the Freezing Point of AqueousEngine CoolantsD3634 Test Method for Trace Chloride Ion in Engine Cool-antsD4327 Test Method for Anions in Water by Suppressed IonChromatographyD4340 Test Method for Corrosion of Cast Aluminum Alloysin Engine Coolants Under Heat-Rejecting ConditionsD4725 Terminology for Engine CoolantsD5827 Test Method for Analysis of Engine Coolant forChloride and Other Anions by Ion ChromatographyD5931 Test Method for Density and Relative Density ofEngine Coolant Concentrates and Aqueous Engine Cool-ants by Digital Density Meter1This 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 Oct.1,2011.Published October 2011.DOI:10.1520/D7714-11.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 D6130 Test Method for Determination of Silicon and OtherElements in Engine Coolant by Inductively CoupledPlasma-Atomic Emission SpectroscopyD6660 Test Method for Freezing Point of Aqueous EthyleneGlycol Base Engine Coolants by Automatic Phase Tran-sition MethodD7640 Specification for Engine Coolant Grade GlycerinE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with SpecificationsE394 Test Method for Iron in Trace Quantities Using the1,10-Phenanthroline Method2.2 Other Standards:3Federal Method 2540B Total Dissolved Solids Dried at103-105C3.Terminology3.1 Definitions:3.1.1 other glycols,nin ethylene glycol base enginecoolant,diethylene glycol,triethylene glycol,tetraethyleneglycol,propylene glycol,dipropylene glycol,tripropyleneglycol,and 1,3-propanediol.3.1.2 other glycols,nin propyle
