Designation:C 1094 01(Reapproved 2006)Standard Guide forFlexible Removable Insulation Covers1This standard is issued under the fixed designation C 1094;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(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide recommends the criteria to be considered inspecifying removable insulation covers for surfaces operatingin air at temperatures above ambient.1.2 A removable insulation cover is fabricated from afibrous insulation material encased in a tailored fabric or wiremesh enclosure,or both.The fabric seams are typically heldtogether with thread,metal rings,or staples,or combinationthereof.These covers must be designed and fabricated to allowa close fit with tight joints over piping,elbows,flanges,valves,and tanks.They are intended to be easily removed and replacedto allow for periodic access to the surfaces they cover.1.3 In addition to thermal performance,there are otherperformance requirements of removable covers.These mayinclude,but are not limited to:1.3.1 Temperature exposure,1.3.2 Chemical and weather exposure,1.3.3 Acoustical,and1.3.4 Fire endurance.1.4 The materials from which the cover is made mayinclude,but are not limited to:1.4.1 Insulation media,1.4.2 Fabric,metal mesh enclosure,or foil enclosure,1.4.3 Seam materials(thread,metal hooks,etc.),and1.4.4 Attachment system(hook and loop attachment,straps,wire,etc.).1.5 The shape,size,and physical design of the cover variesdepending on the object to be covered.The cover may consistof more than one piece.Pipes,valves,pumps,and flanges aretypical objects to be covered.In many cases,on-site measure-ments need to be made to ensure an acceptable fit.1.6 The values stated in SI units shall be regarded as thestandard.The values given in parentheses are provided forinformation only.1.7 This guide does not intend to establish the criteriarequired in the design of the equipment over which removableinsulation covers are used,nor does this guide establish orrecommend the applicability of removable insulation coversover all surfaces.1.8 It is the responsibility of the user,users agent,or both,to determine applicability of this guide to their specificapplication and to inform the equipment designer of the intentto insulate so that appropriate design criteria can be estab-lished.1.9 This standard does not purport to address all of thesafety problems,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 use1.10 This standard should be used to measure and describethe properties of materials,products,or assemblies in responseto heat and flame under controlled laboratory conditions andshould not be used to describe or appraise the fire hazard orfire risk of materials,products,or assemblies under actual fireconditions.However,results of this test may be used aselements of a fire risk assessment which takes into account allof the factors which are pertinent to an assessment of the firehazard of a particular end use2.Referenced Documents2.1 ASTM Standards:C 165 Test Method for Measuring Compressive Propertiesof Thermal InsulationsC 167 Test Methods for Thickness and Density of Blanketor Batt Thermal InsulationsC 177 Test Method for Steady-State Heat Flux Measure-ments and Thermal Transmission Properties by Means ofthe Guarded-Hot-Plate ApparatusC 335 Test Method for Steady-State Heat Transfer Proper-ties of Pipe InsulationC 411 Test Method for Hot-Surface Performance of High-Temperature Thermal InsulationC 423 Test Method for Sound Absorption and Sound Ab-sorption Coefficients by the Reverberation Room MethodC 547 Specification for Mineral Fiber Pipe Insulation1This 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 April 1,2006.Published April 2006.Originallyapproved in 1988.Last previous edition approved in 2001 as C 1094 01.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.Copyright by ASTM Intl(all rights reserved);Thu Apr 16 08:20:46 EDT 2009Downloaded/printed byLaurentian University pursuant to License Agreement.No further reproductions authorized.C 553 Specification for Mineral Fiber Blanket ThermalInsulation for Commercial and Industrial ApplicationsC 592 Specification for Mineral Fiber Blanket Insulationand Blanket-Type Pipe Insulation(Metal-Mesh Covered)(Industrial Type)C 795 Specification for Thermal Insulation for Use in Con-tact with Austenitic Stainless SteelC 892 Specification for High-Temperature Fiber BlanketThermal InsulationC 1393 Specification for Perpendicularly Oriented
