Designation:C177514Standard Specification forLaminate Protective Jacket and Tape for Use over ThermalInsulation for Outdoor Applications1This standard is issued under the fixed designation C1775;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 addresses the minimum performancefor flexible laminate protective jacket and a pressure sensitiveadhesive tape for use over thermal insulation on pipes,duct,and equipment operating at both above and below ambienttemperatures and installed outdoors,above ground.It does notinclude the following:protective metal jacket,homogenousplastic film jacket materials,modified asphalt jacket materials,and butyl rubber membranes.1.2 This type of material shall consist of multiple layers ofpolymer film and aluminum foil laminated to one another withlayer(s)of reinforcement as an option.1.3 Jacket and tape materials covered by this specificationshall have low water vapor permeance values;however,theyare not necessarily always used as vapor retarders.The watervapor transmission tests address the jacket and tape materialsonly and do not address overlaps or taped joints.All materialsshall be weather resistant and intended to have sufficientstrength to provide protection for mechanical insulation.1.4 Materials covered under this specification shall have ahigh,medium,or low surface emittance.1.5 The top layer shall be on of the following:aluminumfoil,a polymer film,or a polymer coating.1.6 This specification includes jacket materials both withand without factory applied,pressure sensitive adhesives.Thetape materials covered by this specification always have afactory applied,pressure sensitive adhesive.1.7 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.1.8 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 InsulationC1136 Specification for Flexible,Low Permeance VaporRetarders for Thermal InsulationC1263 Test Method for Thermal Integrity of Flexible WaterVapor RetardersC1338 Test Method for Determining Fungi Resistance ofInsulation Materials and FacingsC1371 Test Method for Determination of Emittance ofMaterials Near Room Temperature Using Portable Emis-sometersD774 Test Method for Bursting Strength of PaperD882 Test Method for Tensile Properties of Thin PlasticSheetingD1000 Test Methods for Pressure-Sensitive Adhesive-Coated Tapes Used for Electrical and Electronic Applica-tionsD1204 Test Method for Linear Dimensional Changes ofNonrigid Thermoplastic Sheeting or Film at ElevatedTemperatureD3330 Test Method for Peel Adhesion of Pressure-SensitiveTapeD3759 Test Method for Breaking Strength and Elongation ofPressure-Sensitive TapeE96 Test Methods for Water Vapor Transmission of Materi-alsF1249 Test Method for Water Vapor Transmission RateThrough Plastic Film and Sheeting Using a ModulatedInfrared SensorG154 Practice for Operating Fluorescent Ultraviolet(UV)Lamp Apparatus for Exposure of Nonmetallic Materials1This specification is under the jurisdiction of ASTM Committee C16 onThermal Insulation and is the direct responsibility of Subcommittee C16.40 onInsulation Systems.Current edition approved Oct.15,2014.Published November 2014.Originallyapproved in 2013.Last previous edition approved in 2013 as C1775 13.DOI:10.1520/C1775-14.2For 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 3.Terminology3.1 Definitions:3.1.1 Definitions in Terminology C168 apply to terms usedin this specification.3.1.2 laminate jacket,na thin,flexible sheet materialintended for use as a jacket over thermal insulation on pipe,duct,or equipment,and consisting of multiple layers of plasticfilm and foil bonded together.3.1.2.1 DiscussionA laminate jacket is available with orwithout a factory applied pressure sensitive adhesive.3.1.2.2 DiscussionWhile laminate jacket is commerciallyavailable in different widths,it typically is provided commer-cially in approximately the same width as pipe insulationsections.3.1.3 laminate tape,na thin,flexible sheet material in-tended for use as a tape to seal and secure a comp
