Designation:D498220Standard Test Methods forFlammability Potential Screening Analysis of Waste1This standard is issued under the fixed designation D4982;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 These test methods are used to indicate the fire-producing or fire-sustaining potential of wastes.The followingtest methods can be applied to waste liquids,sludges,or solids:SectionsTest Method ATest Specimen Exposed to Heat andFlame8 10Test Method BTest Specimen Exposed to Spark Source11 and 121.2 This standard is used to measure and describe theresponse of materials,products,or assemblies to heat and flameunder controlled conditions,but does not by itself incorporateall factors required for fire hazard or fire risk assessment of thematerials,products,or assemblies under actual fire conditions.1.3 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.1.4 These test methods are designed and intended as pre-liminary tests to complement quantitative analytical techniquesthat are useful to determine flammability.These test methodsoffer the option and the ability to screen waste for hazardousflammability potential when the analytical techniques are notavailable or the total waste composition is unknown.1.5 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard.Thevalues stated in each system are not necessarily exact equiva-lents;therefore,to ensure conformance with the standard,eachsystem shall be used independently of the other,and valuesfrom the two systems shall not be combined.1.6 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.Specific hazard information is given in Section 6,9.3.1,and10.4.3.1.7 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:2D5681 Terminology for Waste and Waste ManagementD8174 Test Method for Finite Flash Point Determination ofLiquid Wastes by Small-Scale Closed Cup TesterD8175 Test Method for Finite Flash Point Determination ofLiquid Wastes by Pensky-Martens Closed Cup Tester3.Terminology3.1 For definitions of terms used in these test methods,referto Terminology D5681.3.2 Definitions of Terms Specific to This Standard:3.2.1 screening analysisa preliminary qualitative or semi-quantitative test that is designed to efficiently give the userspecific information about a waste that will aid in determiningwaste identification,process compatibility,and safety in han-dling.4.Summary of Test Methods4.1 Method AA test specimen is exposed to heat andflame.The sample is reported as having a positive or negativeflammability potential as described in the test procedure.4.2 Method BSparks from a flint lighter are introduced tothe vapor space immediately above a representative specimenof a waste,and observation is made for a flash in the vaporspace or ignition of the specimen.A flash in the vapor space orignition and burning of the waste indicates a positive flamma-bility potential at ambient temperature.5.Significance and Use5.1 These test methods are intended for use by those in thewaste management industries to aid in identifying the flamma-bility potential or waste materials.In addition to the test1These test methods are under the jurisdiction of ASTM Committee D34 onWaste Management and is the direct responsibility of Subcommittee D34.01.05 onScreening Methods.Current edition approved Dec.1,2020.Published January 2021.Originallyapproved in 1989.Last previous edition approved in 2012 as D4982 12.DOI:10.1520/D4982-20.2For 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 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 Tec
