Designation:E223118An American National StandardStandard Practice forSpecimen Preparation and Mounting of Pipe and DuctInsulation Materials to Assess Surface BurningCharacteristics1This standard is issued under the fixed designation E2231;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 practice describes procedures for specimen prepa-ration and mounting when testing pipe and duct insulationmaterials to assess flame spread and smoke development assurface burning characteristics using Test Method E84.1.2 If the pipe or duct insulation materials to be tested arereflective insulation materials(see 3.2.10 and 3.2.11),thematerials shall be tested using the procedures for specimenpreparation and mounting described in Practice E2599 and notthe procedures described in 6.1 through 6.6.1.3 Testing is conducted with Test Method E84.1.4 This practice does not provide pass/fail criteria that canbe used as a regulatory tool.1.5 Use the values stated in inch-pound units as thestandard,in referee decisions.The values in the SI system ofunits are given in parentheses,for information only;seeIEEE/ASTM SI-10 for further details.1.6 This fire standard cannot be used to provide quantitativemeasures.1.7 Fire testing of products and materials is inherentlyhazardous,and adequate safeguards for personnel and propertyshall be employed in conducting these tests.Fire testinginvolves hazardous materials,operations,and equipment.Thisstandard gives instructions on specimen preparation andmounting,but the fire-test-response method is given in TestMethod E84.See also Section 8.1.8 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredrequirements of the standard.1.9 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.10 This fire standard cannot be used to provide quantita-tive measures.1.11 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:2A390 Specification for Zinc-Coated(Galvanized)SteelPoultry Fence Fabric(Hexagonal and Straight Line)C168 Terminology Relating to Thermal InsulationC1136 Specification for Flexible,Low Permeance VaporRetarders for Thermal InsulationC1224 Specification for Reflective Insulation for BuildingApplicationsC1396/C1396M Specification for Gypsum BoardE84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE176 Terminology of Fire StandardsE2599 Practice for Specimen Preparation and Mounting ofReflective Insulation,Radiant Barrier and Vinyl StretchCeiling Materials for Building Applications to AssessSurface Burning CharacteristicsIEEE/ASTM SI-10 International System of Units(SI)TheModernized Metric System2.2 UL Standards:UL 181 Standard for Safety for Factory-Made Air Ducts andConnectors31This practice is under the jurisdiction of ASTM Committee E05 on FireStandards and is the direct responsibility of Subcommittee E05.22 on SurfaceBurning.Current edition approved March 1,2018.Published April 2018.Originallyapproved in 2002.Last previous edition approved in 2015 as E2231-15.DOI:10.1520/E2231-18.2For 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 Underwriters Laboratories(UL),Corporate Progress,333Pfingsten Rd.,Northbrook,IL 60062.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 3.Terminology3.1 DefinitionsFor definitions of terms used in this prac-tice refer to the terminology contained in Terminology E176.3.2 Definitions of Terms Specific to This Standard:3.2.1 composite,nas related to a pipe or duct insulation,see duct insulation system or pipe insulation system.3.2.2 duct,nas related to heating ventilating,air condi-t
