1、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 numb
2、er 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
3、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
4、 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 Thes
5、e 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 notavaila
