Designation:C148212Standard Specification forPolyimide Flexible Cellular Thermal and Sound AbsorbingInsulation1This standard is issued under the fixed designation C1482;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 specification covers the composition and physicalproperties of lightweight,flexible open-cell polyimide foaminsulation intended for use as thermal and sound-absorbinginsulation for temperatures from-328F up to+572F(-200Cand+300C)in commercial and industrial environments.1.1.1 Annex A1 includes faced polyimide foam as specifiedby the U.S.Navy for marine applications.1.1.2 This standard is designed as a material specificationand not a design document.Physical property requirementsvary by application and temperature.No single test is adequatefor estimating either the minimum or maximum use tempera-ture of polyimide foam under all possible conditions.Consultthe manufacturer for specific recommendations and physicalproperties for specific applications.1.1.3 The use of an appropriate vapor retarder is required inall applications where condensation could occur and cause adecrease in thermal performance or affect other system prop-erties.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard is used to measure and describe theresponse of materials,products,or assemblies to heat and flameunder controlled conditions,but does not by itself incorporateall factors required for fire-hazard or fire-risk assessment of thematerials,products,or assemblies under actual fire conditions.1.4 This standard does not purport to address all of thesafety concerns associated with its use.It is the responsibilityof the user to establish appropriate safety and health practicesand determine the applicability of regulatory requirementsprior to use.NOTE1The subject matter of this material specification is not coveredby any other ASTM specification.There is no known ISO standardcovering the subject of this standard.2.Referenced Documents2.1 ASTM Standards:2C165 Test Method for Measuring Compressive Properties ofThermal InsulationsC168 Terminology Relating to Thermal InsulationC177 Test
