Designation:D301411Standard Test Method forFlame Height,Time of Burning,and Loss of Mass of RigidThermoset Cellular Plastics in a Vertical Position1This standard is issued under the fixed designation D3014;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 is a fire-test-response standard.This test methodcovers a small-scale laboratory screening procedure for com-paring relative extent and time of burning and loss of mass ofrigid thermoset cellular plastics.This test method is to be usedsolely to establish relative burning characteristics and shall notbe considered or used as a fire-hazard classification.1.1.1 This test method shall not be used for materials thatdrip or melt under the test conditions.1.2 During the course of combustion,gases or vapors,orboth,are evolved which are potentially hazardous to personnel.Adequate precautions shall be taken to protect the operator.1.3 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.A specific precau-tionary statement is given in 1.2.1.4 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 materials,products,or assemblies under actualfire conditions.1.5 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.NOTE1There is no known ISO equivalent to this standard.2.Referenced Documents2.1 ASTM Standards:2D883 Terminology Relating to PlasticsD1622 Test Method for Apparent Density of Rigid CellularPlasticsD5025 Specification for Laboratory Burner Used for Small-Scale Burning Tests on Plastic MaterialsE176 Terminology of Fire StandardsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method3.Terminology3.1 DefinitionsFor terms relating to plastics,the defini-tions in this test method are in accordance with TerminologyD883.For terms relating to fire,the definitions in this testmethod are in accordance with Terminology E176.4.Summary of Test Method4.1 The specimen is mounted in a vertical chimney with aglass front and ignited with a bunsen burner for 10 s.Theheight and duration of flame and the mass percent retained bythe specimen are recorded.5.Significance and Use5.1 Tests made on rigid cellular materials in accordancewith the conditions described by this test method can be ofconsiderable value in comparing their burning characteristics.5.2 This test method has been applied to flexible cellularmaterials and other plastics,but no detailed studies have beenconducted to determine its general applicability to thesematerials.5.3 In this procedure,the specimens are subjected to one ormore specific sets of laboratory test conditions.If different testconditions are substituted or the end-use conditions arechanged,it is not always possible by or from this test to predictchanges in the fire-test-response characteristics measured.Theresults are therefore valid only for the fire-test-exposureconditions described in this procedure.6.Apparatus6.1 Test Chimney,conforming to the dimensions in Fig.1,Fig.2,and Fig.3.The body of the chimney shall be made ofnon-corroding metal.Fastened into the chimney is an insertmade of 0.025-mm aluminum foil.The insert is held in placeby a stainless steel channel that carries three pins to support the1This test method is under the jurisdiction of ASTM Committee D20 on Plasticsand is the direct responsibility of Subcommittee D20.30 on Thermal PropertiesCurrent edition approved Feb.1,2011.Published February 2011.Originallyapproved in 1973.Last previous edition approved in 2004 as D3014-04a.DOI:10.1520/D3014-11.2For 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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 specimen.A heat-resistant glass panel forms the front wall ofthe chimney.A scale,in millimetres,graduated at 10-mmintervals shall be provided at one side of the glass panel fordetermining flame height(see Fig.1 and Fig.4).The scale shallbegin 51 mm above the bottom of the chimney.6.2 Timer,capable of measuring to the nearest 0.1 s fordetermining the duration of burning.6.3 BurnerA
