Designation:C113017Standard Practice forCalibration of Thin Heat Flux Transducers1This standard is issued under the fixed designation C1130;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 practice,in conjunction with either Test MethodC177,C518,C1114,or C1363,establishes procedures for thecalibration of heat flux transducers that are dimensionally thinin comparison to their planar dimensions.1.1.1 The thickness of the heat flux transducer shall be lessthan 30%of the narrowest planar dimension of the heat fluxtransducer.1.2 This practice describes techniques for determining thesensitivity,S,of a heat flux transducer when subjected to onedimensional heat flow normal to the planar surface or wheninstalled in a building application.1.3 This practice shall be used in conjunction with PracticeC1046 and Practice C1155 when performing in-situ measure-ments of heat flux on opaque building components.Thispractice is comparable,but not identical,to the calibrationtechniques described in ISO 9869-1.1.4 This practice is not intended to determine the sensitivityof heat flux transducers used as components of heat flow meterapparatus,as in Test Method C518,or used for in-situindustrial applications,as covered in Practice C1041.1.5 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of the standard.1.6 UnitsThe values stated in SI units are to be regardedas standard.The values given in parentheses are provided forinformation only and are not considered standard.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:2C168 Terminology Relating to Thermal InsulationC177 Test Method for Steady-State Heat Flux Measure-ments and Thermal Transmission Properties by Means ofthe Guarded-Hot-Plate ApparatusC518 Test Method for Steady-State Thermal TransmissionProperties by Means of the Heat Flow Meter ApparatusC1041 Practice for In-Situ Measurements of Heat Flux inIndustrial Thermal Insulation Using Heat Flux Transduc-ersC1044 Practice for Using a Guarded-Hot-Plate Apparatus orThin-Heater Apparatus in the Single-Sided ModeC1046 Practice for In-Situ Measurement of Heat Flux andTemperature on Building Envelope ComponentsC1114 Test Method for Steady-State Thermal TransmissionProperties by Means of the Thin-Heater ApparatusC1155 Practice for Determining Thermal Resistance ofBuilding Envelope Components from the In-Situ DataC1363 Test Method for Thermal Performance of BuildingMaterials and Envelope Assemblies by Means of a HotBox Apparatus2.2 ISO Standards:3ISO 9869-1 Thermal insulation Building elements In-situmeasurement of thermal resistance and thermal transmit-tance Part 1:Heat flow meter method3.Terminology3.1 DefinitionsFor definitions of terms relating to thermalinsulating materials,see Terminology C168.3.2 Definitions of Terms Specific to This Standard:1This practice is under the jurisdiction of ASTM Committee C16 on ThermalInsulation and is the direct responsibility of Subcommittee C16.30 on ThermalMeasurement.Current edition approved Sept.1,2017.Published October 2017.Originallyapproved in 1989.Last previous edition approved in 2012 as C1130 07(2012).DOI:10.1520/C1130-17.2For 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.3Available from International Organization for Standardization(ISO),ISOCentral Secretariat,BIBC II,Chemin de Blandonnet 8,CP 401,1214 Vernier,Geneva,Switzerland,http:/www.iso.org.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 3.2.1 maskmaterial(or materials)having the same,orne
