Designation:C139314Standard Specification forPerpendicularly Oriented Mineral Fiber Roll and SheetThermal Insulation for Pipes and Tanks1This standard is issued under the fixed designation C1393;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,dimensions,and physical properties of compression-resistant,perpendicu-larly oriented mineral fiber(rock,slag,or glass)roll and sheetinsulation intended for use on flat,curved,or round surfacesoperating at temperatures between 0F(18C)and 1000F(538C).This product(pipe and tank insulation)is typicallyused on nominal 24 in.(610 mm)or greater diameter surfaces.For specific applications,the actual use temperatures anddiameters shall be agreed upon between the manufacturer andthe purchaser.1.2 The orientation of the fibers within the roll or sheetinsulation is essentially perpendicular to the heated/cooledsurface(parallel to heat flow).This specification does not applyto flat block,board,duct wrap,or preformed pipe mineral fiberinsulation where the insulation fiber orientation is generallyparallel to the heated/cooled surface(across the heat flow).1.3 For satisfactory performance,properly installed protec-tive vapor retarders must be used in below ambient temperatureapplications to reduce movement of moisture/water vaporthrough or around the insulation towards the colder surface.Failure to use a vapor retarder can lead to insulation and systemdamage.Refer to Practice C921 to aid material selection.Although vapor retarders properties are not part of thisspecification,properties required in Specification C1136 arepertinent to application or performance.1.4 When the installation or use of thermal materials,accessories,and systems may pose safety or health problems,the manufacturer shall provide the user-appropriate currentinformation regarding any known problems associated with therecommended use for the products of the company and shallalso recommend protective measures to be employed in theirsafe utilization.The user shall establish appropriate safety andhealth practices and determine the applicability of regulatoryrequirements prior to use.1.5 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.1.6 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:2C165 Test Method for Measuring Compressive Properties ofThermal 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 ApparatusC303 Test Method for Dimensions and Density of Pre-formed Block and BoardType Thermal InsulationC390 Practice for Sampling and Acceptance of ThermalInsulation LotsC411 Test Method for Hot-Surface Performance of High-Temperature Thermal InsulationC447 Practice for Estimating the Maximum Use Tempera-ture of Thermal InsulationsC518 Test Method for Steady-State Thermal TransmissionProperties by Means of the Heat Flow Meter ApparatusC665 Specification for Mineral-Fiber Blanket Thermal Insu-lation for Light Frame Construction and ManufacturedHousingC680 Practice for Estimate of the Heat Gain or Loss and theSurface Temperatures of Insulated Flat,Cylindrical,andSpherical Systems by Use of Computer ProgramsC795 Specification for Thermal Insulation for Use in Con-tact with Austenitic Stainless SteelC921 Practice for Determining the Properties of Jacketing1This specification is under the jurisdiction of ASTM Committee C16 onThermal Insulation and is the direct responsibility of Subcommittee C16.20 onHomogeneous Inorganic Thermal Insulations.Current edition approved Jan.1,2014.Published February 2014.Originallyapproved in 2000.Last previous edition approved in 2011 as C139311.DOI:10.1520/C1393-14.2For 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 Materials for Thermal InsulationC1045 Practice for Calculating Thermal Transmission Prop-erties Under Steady-State ConditionsC1058 Practice for Selecting Temperatures for Evaluatingand Reporting Thermal Properties of Thermal InsulationC1104/C1104M T
