Designation:D301419aStandard 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.Scope*1.1 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.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.Aspecific precautionary 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.1.6 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: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 StandardsE456 Terminology Relating to Quality and StatisticsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE2935 Practice for Conducting Equivalence Testing inLaboratory Applications2.2 ISO Standard:3ISO 13943 Fire SafetyVocabulary3.Terminology3.1 DefinitionsFor definitions of terms relating to plastics,the definitions in this test method are in accordance withTerminology D883.For terms relating to fire,the definitions inthis test method are in accordance with Terminology E176 andISO 13943.In case of conflict,the definitions given in Termi-nology E176 shall prevail.For terms relating to precision andbias and associated issues,the terms used in this test methodare in accordance with the definitions in Terminology E456.4.Summary of Test Method4.1 The specimen is mounted by positioning the specimenin a vertical chimney with a glass front and ignited with abunsen burner for 10 s.The height and duration of flame andthe mass percent retained by the 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.1This 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 Dec.1,2019.Published January 2020.Originallyapproved in 1973.Last previous edition approved in 2019 as D3014-19.DOI:10.1520/D3014-19A.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.*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 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.5.2 This test method has been applied to flexible cellularmaterials and other plastics,but no detailed studies have been
