Designation:C55313Standard Specification forMineral Fiber Blanket Thermal Insulation for Commercialand Industrial Applications1This standard is issued under the fixed designation C553;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.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This specification covers the classification,composition,physical properties,and dimensions of mineral fiber(rock,slag,or glass)blanket intended for use as thermal insulation onsurfaces operating at temperatures between 0F(-18C)and1200F(649C).For specific applications,the actual tempera-ture limits shall be agreed upon between the supplier and thepurchaser.1.2 The orientation of the fibers within the blanket isprimarily parallel to the principal surface(face).This specifi-cation does not cover fabricated pipe and tank wrap insulationwhere the insulation has been cut and fabricated to provide afiber orientation that is perpendicular to the surface(face).1.3 For satisfactory performance,properly installed protec-tive vapor retarders must be used in below ambient temperatureapplications to reduce movement of water vapor through oraround the insulation towards the colder surface.Failure to usea vapor retarder can lead to insulation and system damage.Refer to Practice C921 to aid material selection.Althoughvapor retarders are not part of this specification,propertiesrequired in Specification C1136 are pertinent to application orperformance.1.4 This standard does not purport to provide the perfor-mance requirements of hourly-rated fire systems.Consult themanufacturer for the appropriate system.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 associated with its use.It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations 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 ApparatusC390 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 JacketingMaterials 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 InsulationC1101/C1101M Test Methods for Classifying the Flexibilityor Rigidity of Mineral Fiber Blanket and Board InsulationC1104/C1104M Test Method for Determining the Water1This 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 Nov.1,2013.Published December 2013.Originallyapproved in 1964.Last previous edition approved 2011 as C553 11.DOI:10.1520/C0553-13.2For 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 Vapor Sorption of Unfaced Mineral Fiber InsulationC1114 Test Method for Steady-State Thermal TransmissionProperties by Means of the Thin-Heater ApparatusC1136 Specification for Flexible,Low Permeance VaporRetarders for Thermal InsulationC1304 Test Method for Assessing the Odor Emission ofThermal Insulation MaterialsC1335 Test Method for Measuring Non-Fibrous Content ofMan-Made Rock and Slag Mineral Fiber InsulationC1338 Test Method for Determining Fungi Resistance ofInsulation Materials
