Designation:D804621Standard Guide forPumpability of Heat Transfer Fluids1This standard is issued under the fixed designation D8046;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 guide covers general information,without specificlimits,for selecting and evaluating pumpability characteristicsof heat transfer fluids at both low and high temperature.Thisguide is a compendium of information and does not recom-mend a specific course of action.This guide provides addi-tional information on pumpability topics found in companionguides for evaluating heat transfer fluids,Guides D5372 andD7665.1.2 Pumpability of heat transfer fluids is dependent on bothfluid properties and the design of the fluid handling system thatstores and transports the fluid,and therefore presents a numberof pumping options.This guide is considered particularlyuseful for identifying pumpability options.The listing of teststandards and guides is not all-inclusive and additional stan-dards and guides may be useful.1.3 The values stated in SI units are to be regarded asstandard.1.3.1 ExceptionOther units are provided for informationonly.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.Users of heat transfer fluids should be especially mindful ofpotential fire and explosion hazards.1.5 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:2D92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD97 Test Method for Pour Point of Petroleum ProductsD445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D891 Test Methods for Specific Gravity,Apparent,of LiquidIndustrial ChemicalsD2161 Practice for Conversion of Kinematic Viscosity toSaybolt Universal Viscosity or to Saybolt Furol ViscosityD2270 Practice for Calculating Viscosity Index from Kine-matic Viscosity at 40 C and 100 CD2879 Test Method for Vapor Pressure-Temperature Rela-tionship and Initial Decomposition Temperature of Liq-uids by IsoteniscopeD2887 Test Method for Boiling Range Distribution of Pe-troleum Fractions by Gas ChromatographyD2983 Test Method for Low-Temperature Viscosity of Au-tomatic Transmission Fluids,Hydraulic Fluids,and Lubri-cants using a Rotational ViscometerD4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4175 Terminology Relating to Petroleum Products,LiquidFuels,and LubricantsD5372 Guide for Evaluation of Hydrocarbon Heat TransferFluidsD6304 Test Method for Determination of Water in Petro-leum Products,Lubricating Oils,and Additives by Cou-lometric Karl Fischer TitrationD7042 Test Method for Dynamic Viscosity and Density ofLiquids by Stabinger Viscometer(and the Calculation ofKinematic Viscosity)1This guide is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.L0.06 on Non-Lubricating Process Fluids.Current edition approved Dec.1,2021.Published January 2022.Originallyapproved in 2016.Last previous edition approved in 2016 as D8046 16a.DOI:10.1520/D8046-21.2For 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 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.1D7665 Guide for Evaluation of Biodegradable Heat TransferFluidsE794 Test Method for MeltingAnd Crystallization Tempera-tures By Thermal Analysis3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 For definitions of terms used in this guide,refer toTerminology D4175.3.1.2 cavitation,na process of dropping the local liquidpr
