Designation:C171016Standard Guide forInstallation of Flexible Closed Cell Preformed Insulation inTube and Sheet Form1This standard is issued under the fixed designation C1710;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 recommended installation techniquesfor flexible closed cell pre-formed insulation in tube or sheetform.This guide is applicable to materials manufactured inaccordance with Specification C534(Elastomeric based insu-lation)or Specification C1427(polyolefin based insulation).The materials covered in this guide encompass a servicetemperature of 297 to 300F(183 to 150C)as indicated inthe material specifications referenced above.Many of therecommendations made are specific to below ambient applica-tions only.1.2 The purpose of this guide is to optimize the thermalperformance and longevity of installed closed cell flexibleinsulation systems.By following this guide,the owner,anddesigner can expect to achieve the energy savings expected andprevention of condensation under the specified design condi-tions.This document is limited to installation procedures anddoes not encompass system design.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:2C168 Terminology Relating to Thermal InsulationC534 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 TubingC1427 Specification for Extruded Preformed Flexible Cel-lular Polyolefin Thermal Insulation in Sheet and TubularForm2.2 Other Standards:National Commerical,Industrial Insulation Standards(MICA Manual)3ASHRAE Handbook(Fundamentals Chapter 26)4ASHRAE Handbook(Refrigeration Chapter 33)43.Terminology3.1 DefinitionsTerminology C168 shall be considered asapplying to the terms in this specification.3.2 Definitions of Terms Specific to This Standard:3.2.1 seamsLongitudinal or horizontal cross-sectionswhere insulation meets and must be adhered to itself or othersystem components.3.2.2 butt jointsCross-sections where two pieces of tubu-lar or sheet insulation must be adhered to itself or other systemcomponents.3.2.3 vapor(water)stopsLocations/methods to preventwater or water vapor from traveling from one pipe insulationsection to an adjacent insulation and prevent water travelingdown the annular space between the pipe insulation and thetubular pipe.3.2.4 sleeving/multi layeringApplying another layer ofinsulation over the first layer.This process is used when theinsulation thickness required is greater than that which iscommercially available.This technique is also employed whenproper installation practice requires multiple layers and orstaggered joint application,even if a single layer thickness isavailable.1This 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 Sept.1,2016.Published October 2016.Originallyapproved in 2009.Last previous edition approved in 2015 as C1710 15.DOI:10.1520/C1710-16.2For 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.3Available from MICA(Midwest Insulation ContractorsAssociation)16712 ElmCircle,Omaha,NE 68130.http:/www.micainsulation.org.4Available from American Society of Heating,Refrigerating,and Air-Conditioning Engineers,Inc.(ASHRAE),1791 Tullie Circle,NE,Atlanta,GA30329,http:/www.ashrae.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.Summary of Guide4.1 Proper insulation thickness shall be installed as specifiedand not compromised.The integrity of the insulation systemshall be maintained throughout the application.Never pull orstretch insulation,always push or over-size insulation.4.2 All seams,butt joints,cutouts and termination pointsshall be sealed with a manufacturers approved adhesive toprevent air/moisture intrusion.For below ambient applications,installvaporstopsatallinsulationterminationsorinterruptions,such as at supports,valves and flanges This canbe accomplishe
