Designation:D647110Standard Specification forRecycled Prediluted Aqueous Glycol Base Engine Coolant(50 Volume%Minimum)for Automobile and Light-DutyService1This standard is issued under the fixed designation D6471;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 a recycledprediluted aqueous ethylene glycol(50 volume%minimum)base engine coolant and recycled prediluted aqueous propyleneglycol(50 volume%minimum)base engine coolant for use inautomobiles and light-duty vehicles.Committee D15 hasdeveloped this specification using experience,knowledge andresearch from recycling used aqueous base engine coolant andblends of used aqueous base engine coolant and virgin glycol.This standard does not apply to coolant produced from otherglycol sources such as medical waste,distillation bottoms,airplane/airport deicers and polyester production waste.Thisspecification provides a procedure for evaluating engine cool-ant recycling technologies through the recycling of a referencesynthetic used engine coolant.It also specifies the chemical,physical,and performance requirements for the recycled pre-diluted aqueous glycol base engine coolant that is producedfrom that procedure.When used without further dilution,thisproduct functions effectively during both winter and summer.This material is intended to provide protection against freezing,boiling,and corrosion in automobile or other light-duty servicecooling systems.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are approximateequivalents and provided for information only.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.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 TheHydrometerD1126 Test Method for Hardness in WaterD1176 Practice for Sampling and Preparing Aqueous Solu-tions of Engine Coolants orAntirusts for Testing PurposesD1177 Test Method for Freezing Point of Aqueous EngineCoolantsD1193 Specification for Reagent WaterD1287 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 CoolantsD2847 Practice for Testing Engine Coolants in Car and LightTruck Service1This specification is under the jurisdiction ofASTM Committee D15 on EngineCoolants and is the direct responsibility of Subcommittee D15.15 on RecycledEngine Coolant.Current edition approved April 1,2010.Published May 2010.Originallyapproved in 1999.Last previous edition approved in 2006 as D647106.DOI:10.1520/D6471-10.2For 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.*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 D3306 Specification for Glycol Base Engine Coolant forAutomobile and Light-Duty ServiceD3634 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 ConditionsD5827 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 MeterD6129 Test Method for Silicon in Engine Coolant Concen-trates by Atomic Absorption SpectroscopyD6130 Test Method for Determination of Silicon and OtherElements in Engine Coolant by Inductively CoupledPlasma-Atomic Emission SpectroscopyD6208 Test Method for Repassivati
