Designation:C55216aStandard Specification forCellular Glass Thermal Insulation1This standard is issued under the fixed designation C552;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 U.S.Department of Defense.1.Scope1.1 This specification covers the composition,sizes,dimensions,and physical properties of cellular glass thermalinsulation intended for use on surfaces operating at tempera-tures between 450 and 800F(268 and 427C).It is possiblethat special fabrication or techniques for pipe insulation,orboth,will be required for application in the temperature rangefrom 250 to 800F(121 to 427C).Contact the manufacturerfor recommendations regarding fabrication and applicationprocedures for use in this temperature range.For specificapplications,the actual temperature limits shall be agreed uponbetween the manufacturer and the purchaser.1.2 It is anticipated that single-layer pipe insulation in halfsections or the inner layer of a multilayer system have thepotential to exhibit stress cracks above 250F(122C).1.3 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.1.4 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 ApparatusC203 Test Methods for Breaking Load and Flexural Proper-ties of Block-Type Thermal InsulationC240 Test Methods of Testing Cellular Glass InsulationBlockC302 Test Method for Density and Dimensions of Pre-formed Pipe-Covering-Type Thermal InsulationC303 Test Method for Dimensions and Density of Pre-formed Block and BoardType Thermal InsulationC335/C335M Test Method for Steady-State Heat TransferProperties of Pipe InsulationC390 Practice for Sampling and Acceptance of ThermalInsulation LotsC411 Test Method for Hot-Surface Performance of High-Temperature Thermal InsulationC450 Practice for Fabrication of Thermal Insulating FittingCovers for NPS Piping,and Vessel LaggingC518 Test Method for Steady-State Thermal TransmissionProperties by Means of the Heat Flow Meter ApparatusC585 Practice for Inner and Outer Diameters of ThermalInsulation for Nominal Sizes of Pipe and TubingC692 Test Method for Evaluating the Influence of ThermalInsulations on External Stress Corrosion Cracking Ten-dency of Austenitic Stainless SteelC795 Specification for Thermal Insulation for Use in Con-tact with Austenitic Stainless SteelC871 Test Methods for Chemical Analysis of Thermal Insu-lation Materials for Leachable Chloride,Fluoride,Silicate,and Sodium IonsC1045 Practice for Calculating Thermal Transmission Prop-erties Under Steady-State ConditionsC1058/C1058M Practice for Selecting Temperatures forEvaluating and Reporting Thermal Properties of ThermalInsulationC1114 Test Method for Steady-State Thermal TransmissionProperties by Means of the Thin-Heater ApparatusC1617 Practice for Quantitative Accelerated LaboratoryEvaluation of Extraction Solutions Containing IonsLeached from Thermal Insulation on Aqueous Corrosionof MetalsC1639 Specification for Fabrication Of Cellular Glass PipeAnd Tubing Insulation1This 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 Sept.1,2016.Published September 2016.Originallyapproved in 1965 to replace C381 58 and C343 56.Last previous editionapproved in 2016 as C552 16.DOI:10.1520/C0552-16A.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 D226/D226M Specification for Asphalt-Saturated OrganicFelt Used in Roofing and WaterproofingD312/D312M Specification for Asphalt Used in RoofingE84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE96/E96M Test Methods for Water Vapor Transmission ofMaterials2.2 ISO Documents:3ISO 3951 Sampling Procedure and Charts for Inspection byVar
