Designation:E132113An American National StandardStandard Test Method forDetermining Material Ignition and Flame Spread Properties1This standard is issued under the fixed designation E1321;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 fire test response standard determines materialproperties related to piloted ignition of a vertically orientedsample under a constant and uniform heat flux and to lateralflame spread on a vertical surface due to an externally appliedradiant-heat flux.1.2 The results of this test method provide a minimumsurface flux and temperature necessary for ignition(q o,ig,Tig)and for lateral spread(q o,s,Ts,min),an effective materialthermal inertia value(kc),and a flame-heating parameter()pertinent to lateral flame spread.1.3 The results of this test method are potentially useful topredict the time to ignition,tig,and the velocity,V,of lateralflame spread on a vertical surface under a specified externalflux without forced lateral airflow.Use the equations inAppendix X1 that govern the ignition and flame-spread pro-cesses and which have been used to correlate the data.1.4 This test method is potentially useful to obtain results ofignition and flame spread for materials.Data are reported inunits for convenient use in current fire growth models.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.6 This standard is used to measure and describe theresponse of materials,products,or assemblies to heat andflame under controlled conditions,but does not by itselfincorporate all factors required for fire hazard or fire riskassessment of the materials,products,or assemblies underactual fire conditions.1.7 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.For specific hazardstatements,see Section 7.1.8 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.2.Referenced Documents2.1 ASTM Standards:2E84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE162 Test Method for Surface Flammability of MaterialsUsing a Radiant Heat Energy SourceE176 Terminology of Fire StandardsE286 Test Method for Surface Flammability of BuildingMaterials Using an 8-ft(2.44-m)Tunnel Furnace(With-drawn 1991)3E648 Test Method for Critical Radiant Flux of Floor-Covering Systems Using a Radiant Heat Energy SourceE970 Test Method for Critical Radiant Flux of ExposedAtticFloor Insulation Using a Radiant Heat Energy SourceE1317 Test Method for Flammability of Marine SurfaceFinishes2.2 ASTM Adjuncts:ASTMDetailed drawings(19),construction information,and partslist(Adjunct to E1317)43.Terminology3.1 DefinitionsFor definitions of terms used in this testmethod,refer to Terminology E176.3.2 Definitions of Terms Specific to This Standard:3.2.1 backing board,na noncombustible insulating board,mounted behind the specimen during actual testing to satisfythe theoretical analysis assumption of no heat loss through thespecimen.It shall be roughly 25 6 5 mm thick with a densityno greater than 200 6 50 kg/m3.3.2.2 dummy specimen,na noncombustible insulatingboard used for stabilizing the operating condition of theequipment,roughly 20 6 5 mm in thickness with a density of750 6 100 kg/m3.1This test method is under the jurisdiction of ASTM Committee E05 on FireStandards and is the direct responsibility of Subcommittee E05.22 on SurfaceBurning.Current edition approved Oct.1,2013.Published October 2013.Originallyapproved in 1990.Last previous edition approved in 2009 as E1321 09.DOI:10.1520/E1321-13.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from ASTM Headquarters.Order ADJE1317.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.2.1 DiscussionThe dummy specimen is mounted inthe apparatus in the position of the test specimen and removedonly when a test specimen is to be inserted.For the ignitiontests,the dummy specimen board shall have a hole at the50-mm position,for mounting the fluxmeter.3.2.3 effective thermal property,nthermal properties de-rived from heat-conduction theory applied to ignition/flame-spread data treating the material as homogenous in structure.3.2.4
