Designation:D811618Standard Specification forFully-Formulated Non-Aqueous Engine Coolant forHeavy-Duty Engines1This standard is issued under the fixed designation D8116;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 A non-aqueous engine coolant is a glycol,diol,triol,ormixtures thereof,based heat transfer fluid containing less than1.0%water when formulated and intended for final usewithout dilution with water.(Definition from TerminologyD4725.)1.2 This specification covers the requirements for fullyformulated non-aqueous glycol base coolants for coolingsystems of heavy-duty engines.These coolants will functioneffectively during both winter and summer to provide protec-tion against corrosion,cavitation,freezing,boiling,and exces-sive viscosity.1.3 This specification is intended to cover the requirementsfor non-aqueous engine coolants prepared from virgin glycols,diols,or triols,or mixtures thereof.1.4 Coolants meeting this specification exhibit very lowvapor pressures under all operating conditions,thereby avoid-ing the creation and collapse of coolant vapor,the primarycause of pump and cylinder liner cavitation erosion.They mayadditionally contain additives that provide traditional anti-cavitation erosion coatings but there is no requirement that theymust.Non-aqueous engine coolants usually contain one ormore carboxylates and do not normally contain nitrites.It issuggested that coolant testing be undertaken at normal manu-facturers recommended intervals to monitor degradation prod-ucts.The low vapor pressures inherent in coolants that meetthis specification also provide protection from hot surfacescaling,as liquid coolant is in contact with all hot metalsurfaces of the engine cooling system at all times.1.5 Water is a contaminant to non-aqueous engine coolantsand it is suggested that water content be tested periodicallywith test strips to ideally keep water content of the coolant at3%or less.Increases in water cause an undesirable drop in theboiling point.It is instructive that the glassware corrosiontesting per this specification is conducted at 6%corrosivewater.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 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.1.8 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:2D4725 Terminology for Engine Coolants and Related FluidsD5827 Test Method for Analysis of Engine Coolant forChloride and Other Anions by Ion ChromatographyD6210 Specification for Fully-Formulated Glycol Base En-gine Coolant for Heavy-Duty EnginesD7583 Test Method for John Deere Coolant Cavitation TestD8085 Specification for Non-Aqueous Engine Coolant forAutomobile and Light-Duty Service3.Requirements3.1 The non-aqueous coolant shall meet all the physical,chemical,and performance requirements of SpecificationD8085,Tables 1,2,and 3.3.2 The non-aqueous coolant shall be suitable for use in aproperty maintained cooling system in normal service for aminimum of two years(see Appendix X1).3.3 The non-aqueous coolant shall not contain more than 50g/g sulfate ion(Test Method D5827).3.4 The non-aqueous coolant shall conform to the require-ments of Annex A1.1This specification is under the jurisdiction ofASTM Committee D15 on EngineCoolants and Related Fluids and is the direct responsibility of SubcommitteeD15.22 on Non-Aqueous Coolants.Current edition approved April 1,2018.Published April 2018.DOI:10.1520/D8116-18.2For 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 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 4.Keywords4.1 cavitation;heavy-duty engine coolant;non-aqueouscoolantANNEX(Mandator
