Designation:C169616Standard Guide forIndustrial Thermal Insulation Systems1This standard is issued under the fixed designation C1696;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 guide covers information on selection of insulationmaterials,systems design,application methods,protectivecoverings,guarantees,inspection,testing,and maintenance ofthermal insulation primarily for industrial applications in atemperature range of 320 to 1200F(195.5 to 648.8C).1.2 This guide is intended to provide practical guidelines,by applying acceptable current practice while indicating thebasic principles by which new materials can be assessed andadapted for use under widely differing conditions.Designengineers,the general contractors,the fabricators,and theinsulation contractors will find this guide helpful.1.3 Although some insulation system designs can serve asfire protection,this guide does not address the criteria specificto that need.API 521 Guide for Pressure-Relieving andDepressuring Systems is recommended as a reference for fireprotection.This guide will however address the fire propertiesof insulation materials.1.4 This guide is not intended for commercial,architectural,acoustical,marine,vehicle transport,or military use.1.5 This guide does not address insulation system design forrefractory linings or cold boxes whereby these are typicallypackage units and of a proprietary insulation design.1.6 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.1.7 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:2A167 Specification for Stainless and Heat-ResistingChromium-Nickel Steel Plate,Sheet,and Strip(With-drawn 2014)3A240/A240M Specification for Chromium and Chromium-Nickel Stainless Steel Plate,Sheet,and Strip for PressureVessels and for General ApplicationsA653/A653M Specification for Steel Sheet,Zinc-Coated(Galvanized)or Zinc-Iron Alloy-Coated(Galvannealed)by the Hot-Dip ProcessA792/A792M SpecificationforSteelSheet,55%Aluminum-Zinc Alloy-Coated by the Hot-Dip ProcessB209 Specification for Aluminum and Aluminum-AlloySheet and PlateC165 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 ApparatusC195 Specification for Mineral Fiber Thermal InsulatingCementC203 Test Methods for Breaking Load and Flexural Proper-ties of Block-Type Thermal InsulationC209 Test Methods for Cellulosic Fiber Insulating BoardC240 Test Methods of Testing Cellular Glass InsulationBlockC272/C272M Test Method for Water Absorption of CoreMaterials for Sandwich ConstructionsC302 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 Transfer1This guide is under the jurisdiction of ASTM Committee C16 on ThermalInsulation and is the direct responsibility of Subcommittee C16.40 on InsulationSystems.Current edition approved March 1,2016.Published March 2016.Originallyapproved in 2012.Last previous edition approved in 2015 as C1696 15.DOI:10.1520/C1696-16.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Properties of Pipe InsulationC351 Test Method for Mean Specific Heat of ThermalInsulation(Withdrawn 2008)3C356 Test Method for Linear Shrinkage of Preformed High-Temperature Thermal Insulation Subjected to SoakingHeatC411 Test Method for Hot-Surface Performance of High-Temperature Thermal InsulationC446 Test Method for Breaking Load and Calculated Modu-lus of Rupture of Preformed Insulation for Pipes(With-drawn 2002)3C447 Practice for Estimating the Maximum Use Tempera-ture of Thermal InsulationsC449 Specification for Mineral Fiber Hydraulic-SettingThermal Insulating and F
