Designation:C534/C534M16Standard Specification forPreformed Flexible Elastomeric Cellular Thermal Insulationin Sheet and Tubular Form1This standard is issued under the fixed designation C534/C534M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers preformed flexible elastomericcellular thermal insulation in sheet and tubular form.Grade 1covers materials to be used on commercial or industrialsystems with operating temperatures from 183 to 104C297 to 220F,Grade 2 covers material used on industrialsystems with operating temperatures from 183 to 175C297 to 350F,and Grade 3 covers material used onindustrial systems with operating temperatures from 183 to120C 297 to 250F where halogens are not permitted.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 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:2C168 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 LotsC335 Test Method for Steady-State Heat Transfer Propertiesof Pipe InsulationC411 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 ApparatusC534 Specification for Preformed Flexible Elastomeric Cel-lular Thermal Insulation in Sheet and Tubular FormC585 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 Practice for Selecting Temperatures for Evaluatingand Reporting Thermal Properties of Thermal InsulationC1114 Test Method for Steady-State Thermal TransmissionProperties by Means of the Thin-Heater ApparatusC1304 Test Method for Assessing the Odor Emission ofThermal Insulation MaterialsC1427 Specification for Extruded Preformed Flexible Cel-lular Polyolefin Thermal Insulation in Sheet and TubularFormC1763 Test Method for Water Absorption by Immersion ofThermal Insulation MaterialsD883 Terminology Relating to PlasticsD1622 Test Method for Apparent Density of Rigid CellularPlasticsD1667 Specification for Flexible Cellular MaterialsPoly(Vinyl Chloride)Foam(Closed-Cell)E84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE96/E96M Test Methods for Water Vapor Transmission ofMaterialsE177 Practice for Use of the Terms Precision and Bias inASTM Test Methods1This specification is under the jurisdiction of ASTM Committee C16 onThermal Insulation and is the direct responsibility of Subcommittee C16.22 onOrganic and Nonhomogeneous Inorganic Thermal Insulations.Current edition approved Oct.1,2016.Published October 2016.Originallyapproved in 1964.Last previous edition approved in 2014 as C0534/C534M 14.DOI:10.1520/C0534_C0534M-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 E456 Terminology Relating to Quality and StatisticsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE2231 Practice for Specimen Preparation and Mounting ofPipe and Duct Insulation Materials to Assess SurfaceBurning Characteristics2.2 Other Standards:3CAN/ULC-S102 Standard Method of Test for Surface Burn-ing Characteristics of Building Materials and Assemblies3.Terminology3.1 DefinitionsTerms used in this specification are definedin Terminology C168 and in Ter
