Designation:C172817Standard Specification forFlexible Aerogel Insulation1This standard is issued under the fixed designation C1728;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 classification and perfor-mance of flexible aerogel thermal insulation.This will coverthe range of continuous exposure operating temperatures from321F(196C)up to 1200F(649C).1.2 For satisfactory performance,properly installed protec-tive vapor retarders or barriers shall be used on below ambienttemperature applications to reduce movement of moisturethrough or around the insulation to the colder surface.Failureto use a vapor retarder or barrier could lead to insulation andsystem non-performance.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 The following safety hazards caveat pertains only to thetest methods described in this specification.This standard doesnot purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of thisstandard to establish appropriate safety and health practicesand determine the applicability of regulatory limitations priorto use.2.Referenced Documents2.1 ASTM Standards:2C165 Test Method for Measuring Compressive Properties ofThermal InsulationsC167 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 ApparatusC303 Test Method for Dimensions and Density of Pre-formed Block and BoardType Thermal InsulationC335 Test Method for Steady-State Heat Transfer Propertiesof Pipe InsulationC356 Test Method for Linear Shrinkage of Preformed High-Temperature Thermal Insulation Subjected to SoakingHeatC390 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 ApparatusC795 Specification for Thermal Insulation for Use in Con-tact with Austenitic Stainless SteelC1045 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 WaterVapor Sorption of Unfaced Mineral Fiber InsulationC1114 Test Method for Steady-State Thermal TransmissionProperties by Means of the Thin-Heater ApparatusC1338 Test Method for Determining Fungi Resistance ofInsulation Materials and FacingsC1617 Practice for Quantitative Accelerated LaboratoryEvaluation of Extraction Solutions Containing IonsLeached from Thermal Insulation on Aqueous Corrosionof MetalsC1763 Test Method for Water Absorption by Immersion ofThermal Insulation MaterialsE84 Test Method for Surface Burning Characteristics ofBuilding Materials1This 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 Feb.1,2017.Published February 2017.Originallyapproved in 2012.Last previous edition approved in 2013 as C1728 13.DOI:10.1520/C1728-17.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 E2231 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 Definitions:For definitions used in this specification,seeTerminology A3.3.1.1 flexible aerogel insulation,na flexible insulationcontaining a composit
