Designation:D330614Standard Specification forGlycol Base Engine Coolant for Automobile and Light-DutyService1This standard is issued under the fixed designation D3306;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 ethyleneglycol or propylene glycol base engine coolants used inautomobiles or other light duty service cooling systems.Whenconcentrates are used at 40 to 70%concentration by volume inwater,or when prediluted glycol base engine coolants 50volume%or higher engine coolant concentrate are usedwithout 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 TypeDescriptionIEthylene glycol base concentrateIIPropylene glycol base concentrateVEthylene glycol base concentratecontaining glycerinIIIEthylene glycol predilute 50 volume%or higherengine coolant concentrateIVPropylene glycol predilute 50 volume%or higherengine coolant concentrateVIEthylene glycol base predilutecontaining glycerin 50 volume%or higher enginecoolant concentrateNOTE1This specification is based on the knowledge of the perfor-mance of engine coolants prepared from new or virgin ingredients.Thisspecification shall also apply to engine coolants prepared using glycolgenerated from recycled or reprocessed used coolant or reprocessedindustrial-source glycol,provided that said glycol meets the requirementsof Specification E1177.Separate specifications(D6471 and D6472)existfor engine coolants prepared from recycled or reprocessed used coolant orreprocessed industrial-source glycol that does not meet the requirementsestablished in Specification E1177.This specification shall also apply toglycol based engine coolants prepared using fully refined glycerinprovided that said glycerin meets the requirements for SpecificationD7640.1.3 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.NOTE2This specification applies to glycol base engine coolant forautomobiles and light duty service.Specifications D4985 and D6210 existfor heavy duty engine service.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 Coolants1This 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 15,2014.Published May 2014.Originallyapproved in 1974.Last previous edition approved in 2011 as D3306 11.DOI:10.1520/D3306-14.2For 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 D2809 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 fo
