Designation:E265212An American National StandardStandard Test Method forBehavior of Materials in a Tube Furnace with a Cone-shapedAirflow Stabilizer,at 750C1This standard is issued under the fixed designation E2652;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 test method covers the determi-nation under specified laboratory conditions of combustioncharacteristics of building materials.1.2 Limitations of this fire-test response test method areshown below.1.2.1 This test method does not apply to laminated or coatedmaterials.1.2.2 This test method is not suitable or satisfactory formaterials that soften,flow,melt,intumesce or otherwiseseparate from the meeasuring thermocouple.1.2.3 This test method does not provide a measure of anintrinsic property.1.2.4 This test method does not provide a quantitativemeasure of heat generation or combustibility;it simply servesas a test method with selected(end point)measures ofcombustibility.1.2.5 This test method does not measure the self-heatingtendencies of materials.1.2.6 In this test method materials are not being tested in thenature and form used in building aplications.The test specimenconsists of a small,specified volume that is either(1)cut froma thick sheet;(2)assembled from multiple thicknesses of thinsheets;or(3)placed in a container if composed of grarnularpowder or loose fiber materials.1.2.7 Results from this test method apply to the specific testapparatus and test conditions and are likely to vary whenchanges are made to one or more of the following:(1)the size,shape,and arrangement of the specimen;(2)the distribution oforganice content;(3)the exposure temperature;(4)the airsupply;(5)the location of thermocouples.1.3 This test method references notes and footnotes thatprovide explanatory information.These notes and footnotes,excluding those in tables and figures,shall not be considered asrequirements of this test method.1.4 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.1.5 This test method is technically equivalent to ISO 1182.1.6 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 FIre testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.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:2E136 Test Method for Behavior of Materials in a VerticalTube Furnace at 750CE176 Terminology of Fire Standards2.2 ISO Standards:3ISO 1182 Reaction to Fire Tests for Building Products Non-combustibility TestISO 13943 Fire Safety VocabularyISO 5725-2:1994 Accuracy(trueness and precision)of Mea-sured Methods and Results Part 2:Basic Method for theDetermination of Repeatability and Reproducibility of aStandard Measurement Method2.3 Other Standards:4IMO Fire Test Procedures Code1This test method is under the jurisdiction of ASTM Committee E05 on FireStandards and is the direct responsibility of Subcommittee E05.23 on Combustibil-ity.Current edition approved July 1,2012.Published August 2012.Originallyapproved in 2009.Last previous edition approved in 2009 as E265209a.DOI:10.1520/E2652-12.2For 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 American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.4Available from International Maritime Origanization,55 Victoria St.,London,SWIH0EU,United Kingdom,http:/www.imo.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.Terminology3.1 DefinitionsFor definitions of terms found in this testmethod,refer to Terminology E176 and ISO 13943.In case ofconflict,the definitions given in Terminology E176 shallprevail.3.2 Definitions of Terms Specific to This Standard:3.2.1 homogeneous product,na product with nominallyuniform density and composition.3.2.2 non-homogeneous product,na product that does notsatisfy the requirements of a homogeneous product.3.2.2.1 DiscussionNon-homogeneous products are oftencomposed of more th
