Designation:C149716Standard Specification forCellulosic Fiber Stabilized Thermal Insulation1This standard is issued under the fixed designation C1497;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 spray-applied cellulosic fiber stabilized thermalinsulation applied to open or closed ceiling spaces,regardlessof slope,where temperatures range from 49 to 194F(45 to90C).1.2 Stabilized cellulosic fiber thermal insulation is producedby the addition of adhesive(s)to loose-fill cellulosic fiberinsulation.The adhesive(s)are either added to the insulation attime of manufacture and,if necessary,activated by the additionof water when installed or the adhesive(s)are otherwise addedto the insulation at the time of installation.1.3 This is a material specification that is not intended todeal with methods of application that are supplied by themanufacturer.1.4 The values stated in inch-pound units are to be regardedas standard.The SI units given in parentheses are for informa-tion only.1.5 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:2C167 Test Methods for Thickness and Density of Blanket orBatt Thermal InsulationsC168 Terminology Relating to Thermal InsulationC177 Test Method for Steady-State Heat Flux Measure-ments and Thermal Transmission Properties by Means ofthe Guarded-Hot-Plate ApparatusC739 Specification for Cellulosic Fiber Loose-Fill ThermalInsulationC1149 Specification for Self-Supported Spray Applied Cel-lulosic Thermal InsulationC1304 Test Method for Assessing the Odor Emission ofThermal Insulation MaterialsC1338 Test Method for Determining Fungi Resistance ofInsulation Materials and FacingsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE970 Test Method for Critical Radiant Flux of ExposedAtticFloor Insulation Using a Radiant Heat Energy Source3.Terminology3.1 DefinitionsFor definitions of terms used in thisspecification,see Terminology C168.3.2 Definitions of Terms Specific to This Standard:3.2.1 shrinkagedecrease in thickness that occurs from thetime of installation until the insulation is dry(see 7.2.5).3.2.2 stabilized cellulosea cellulosic insulation producttreated to resist,after drying,further settling of no more than5%.4.Materials and Manufacture4.1 The basic material shall be recycled cellulosic fibermade from selected paper or paperboard stock.Additives areintroduced to affect different performance characteristics,in-cluding those related to fire performance,processing,andhandling.An adhesive is added to the insulation product toresist long-term settling of the insulation after installation andcuring.4.2 The materials are processed into a form suitable forinstallation by a pneumatic method.4.3 The adhesive is added to the product either at the time ofmanufacture or at the time of installation by means of a liquidspray.5.Physical and Chemical Properties5.1 DensityThe density of conditioned stabilized insula-tion in lb/ft3(kg/m3)shall be determined in accordance withSection 7.5.2 CorrosivenessThe loose-fill insulation material shallbe tested for corrosiveness in accordance with Section 8.The1This specification is under the jurisdiction of ASTM Committee C16 onThermal Insulation and is the direct responsibility of Subcommittee C16.23 onBlanket and Loose Fill Insulation.Current edition approved Oct.1,2016.Published October 2016.Originallyapproved in 2001.Last previous edition approved in 2012 as C1497 12.DOI:10.1520/C1497-16.2For 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 States1 composition of the insulation material shall be such that aftertesting,no perforation of the 0.003 in.(0.076 mm)metalspecimens shall be evident when the specimens are observedover a 40-W appliance light bulb.Notches extending into thecoupon 0.1 in.(3 mm)or less from any edge shall be ignored.5.3 Critical Radiant FluxWhen tested in accordance withSection 9,the critical radiant flux shall be equal to or greaterthan 0.11 Btu/ft2s(0.12 W/cm2).All values shall be reported totwo significant digits.5.4 Fungi ResistanceThe loose-fill insulation materialshall be tested and pass fungi resistance as specified in Section10.
