Designation:C54717Standard Specification forMineral Fiber Pipe Insulation1This standard is issued under the fixed designation C547;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This specification covers mineral fiber insulation pro-duced to form hollow cylinders for standard pipe and tubingsizes.Use mineral fiber pipe insulation that has been eithermolded or precision v-grooved,with one or more walls splitlongitudinally for use on pipe temperatures up to 1400F(760C).1.2 For satisfactory performance,use properly installedprotective vapor retarders or barriers on sub-ambient tempera-ture applications to reduce movement of moisture through oraround the insulation to the colder surface.Failure to use avapor barrier can lead to insulation and system damage.Referto Practice C921 to aid material selection.1.3 Flexiblemineralfiberwrapproductssuchasperpendicular-oriented fiber insulation rolls,non-precision ormanually scored block or board,or flexible boards or blanketsused as pipe insulation,are not covered by this specification.1.4 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.1.5 ForNavalSeaSystemsCommand(NAVSEA)acceptance,materials must also comply with SupplementalRequirements.See Annex A1 of this standard.1.6 The following safety hazards caveat applies to the testmethods portion,Section 11,only:This standard does notpurport to address all of the safety concerns,if any,associatedwith its use.It is the responsibility of the user of this standardto establish appropriate safety and health practices anddetermine the applicability of regulatory limitations prior touse.1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2C167 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 ApparatusC302 Test Method for Density and Dimensions of Pre-formed Pipe-Covering-Type Thermal InsulationC335/C335M Test Method for Steady-State Heat TransferProperties of 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 InsulationsC585 Practice for Inner and Outer Diameters of ThermalInsulation for Nominal Sizes of Pipe and TubingC680 Practice for Estimate of the Heat Gain or Loss and theSurface Temperatures of Insulated Flat,Cylindrical,andSpherical Systems by Use of Computer ProgramsC795 Specification for Thermal Insulation for Use in Con-tact with Austenitic Stainless SteelC921 Practice for Determining the Properties of JacketingMaterials for Thermal InsulationC1045 Practice for Calculating Thermal Transmission Prop-erties Under Steady-State ConditionsC1058/C1058M Practice for Selecting Temperatures for1This specification is under the jurisdiction of ASTM Committee C16 onThermal Insulation and is the direct responsibility of Subcommittee C16.20 onHomogeneous Inorganic Thermal Insulations.Current edition approved Sept.1,2017.Published September 2017.Originallyapproved in 1964.Last previous edition approved in 2015 as C547 15.DOI:10.1520/C0547-17.2For 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 Evaluating and Reporting Thermal Properties of ThermalInsulationC1104/C1104M Test Method for Determining the WaterVapor Sorption of Unfaced Mineral Fiber InsulationC1335
