Designation:C147006(Reapproved 2013)Standard Guide forTesting the Thermal Properties of Advanced Ceramics1This standard is issued under the fixed designation C1470;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 guide covers the thermal property testing of ad-vanced ceramics,to include monolithic ceramics,particulate/whisker-reinforced ceramics,and continuous fiber-reinforcedceramic composites.It is intended to provide guidance andinformation to users on the special considerations involved indetermining the thermal properties of these ceramic materials.1.2 Five thermal properties(specific heat capacity,thermalconductivity,thermal diffusivity,thermal expansion,andemittance/emissivity)are presented in terms of their definitionsand general test methods.The relationship between thermalproperties and the composition,microstructure,and processingof advanced ceramics(monolithic and composite)is brieflyoutlined,providing guidance on which material and specimencharacteristics have to be considered in evaluating the thermalproperties of advanced ceramics.Additional sections describesampling considerations,test specimen preparation,and report-ing requirements.1.3 Current ASTM test methods for thermal properties aretabulated in terms of test method concept,testing range,specimenrequirements,standards/referencematerials,capabilities,limitations,precision,and special instructions formonolithic and composite ceramics.1.4 This guide is based on the use of current ASTMstandards for thermal properties where appropriate and on thedevelopment of new test standards where necessary.It is notthe intent of this guide to rigidly specify particular thermal testmethods for advanced ceramics.Guidance is provided on howto utilize the most commonly available ASTM thermal testmethods,considering their capabilities and limitations.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.See IEEE/ASTM SI 10.1.6 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:22.1.1 Specific Heat:C351 Test Method for Mean Specific Heat of ThermalInsulation(Withdrawn 2008)3D2766 Test Method for Specific Heat of Liquids and SolidsE1269 Test Method for Determining Specific Heat Capacityby Differential Scanning Calorimetry2.1.2 Thermal Conductivity:C177 Test Method for Steady-State Heat Flux Measure-ments and Thermal Transmission Properties by Means ofthe Guarded-Hot-Plate ApparatusC182 Test Method for Thermal Conductivity of InsulatingFirebrickC201 Test Method for Thermal Conductivity of RefractoriesC202 Test Method for Thermal Conductivity of RefractoryBrickC408 Test Method for Thermal Conductivity of WhitewareCeramicsC518 Test Method for Steady-State Thermal TransmissionProperties by Means of the Heat Flow Meter ApparatusC767 Test Method for Thermal Conductivity of CarbonRefractoriesC1044 Practice for Using a Guarded-Hot-Plate Apparatus orThin-Heater Apparatus in the Single-Sided ModeC1045 Practice for Calculating Thermal Transmission Prop-erties Under Steady-State ConditionsC1113 Test Method for Thermal Conductivity of Refracto-ries by Hot Wire(Platinum Resistance ThermometerTechnique)C1114 Test Method for Steady-State Thermal TransmissionProperties by Means of the Thin-Heater ApparatusC1130 Practice for Calibrating Thin Heat Flux TransducersE1225 Test Method for Thermal Conductivity of Solids1This guide is under the jurisdiction of ASTM Committee C28 on AdvancedCeramics and is the direct responsibility of Subcommittee C28.03 on PhysicalProperties and Non-Destructive Evaluation.Current edition approved Feb.1,2013.Published March 2013.Originallyapproved in 2000.Last previous edition approved in 2006 as C1470 06.DOI:10.1520/C1470-06R13.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Using the Guarded-Comparative-Longitudinal Heat FlowTechniqueE1530 Test Method for Evaluating the Resistance to Ther-mal Transmission of Materials by the Guarded Heat FlowMeter Technique2.1.3 Thermal Expansion:C372 Test Method for Linear Thermal Expansion of Porce-lain Enamel and Glaze Frits and Fired Ceramic WhitewarePro
