Designation:E263912Standard Test Method forBlast Resistance of Trash Receptacles1This standard is issued under the fixed designation E2639;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 test method provides a procedure for characterizingthe performance of a trash receptacle when an explosive isdetonated within the receptacle.1.1.1 The procedure determines the extent and location offragments produced during the explosion,and whetherbreaches are created in the exterior surfaces of the trashreceptacle.1.1.2 Appendix X1 provides guidance for determining themagnitude of blast waves(that is,external overpressures)developed.1.1.3 Effects due to a fireball resulting from the detonationof an explosive within a trash receptacle are beyond the scopeof the test method.1.2 This test method is intended to be performed in open-airtest arenas.1.3 The values stated in SI units are to be regarded as thestandard.The values stated in parentheses are for informationonly.1.4 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:2D638 Test Method for Tensile Properties of PlasticsD747 Test Method for Apparent Bending Modulus of Plas-tics by Means of a Cantilever BeamD790 Test Methods for Flexural Properties of Unreinforcedand Reinforced Plastics and Electrical Insulating Materi-alsD882 Test Method for Tensile Properties of Thin PlasticSheetingD883 Terminology Relating to PlasticsE2740 Specification for Trash Receptacles Subjected toBlast Resistance Testing2.2 Government Standards:DOD 4145.26 M Department of Defense:DOD ContractorsSafety Manual for Ammunition and Explosives3DOD 6055.9 STD Department of Defense:DOD Ammuni-tion and Explosives Safety Standards4Voluntary Product Standard PS 1 Structural Plywood53.Terminology3.1 For terminology generally associated with explosives,refer to the glossaries given in DOD 4145.26 M and DOD6055.9 STD.3.1.1 Some of the definitions in this standard(3.2)are eitheradopted as exact copies,or are adapted,from DOD 4145.26 M.Where adapted,changes to the DOD definitions were madeonly to clarify the meaning or to incorporate related terms thatalso are defined in this terminology section.3.1.2 The DOD source is identified parenthetically at theright margin following the definition.3.2 Definitions:3.2.1 alias,na false low-frequency component that ap-pears when reconstructing analog data that are sampled at aninsufficient rate.3.2.2 detonation,n(1)a violent chemical reaction within achemical compound or mechanical mixture resulting in heatand pressure;(2)a reaction that proceeds through the reactedmaterial toward the unreacted material at a supersonic velocity.3.2.2.1 DiscussionThe result of the chemical reaction isexertion of extremely high pressure on the surrounding me-dium forming a propagating shock wave that is originally ofsupersonic velocity.DOD 4145.26 M1This test method is under the jurisdiction of ASTM Committee E54 onHomeland Security Applications and is the direct responsibility of SubcommitteeE54.08 on Operational Equipment.Current edition approved Feb.15,2012.Published March 2012.Originallyapproved in 2009.Last previous edition approved in 2009 as E2639 09a.DOI:10.1520/E2639-12.2For 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 the Defense Technical Information Center,8725 John J.Kingman Road,Suite 0944,Ft.Belvoir,VA 22060 6128.4Available from the worldwide web at:http:/www.ddesb.pentagon.mil/DoD6055.9-STD%205%20Oct%202004.pdf.5Available from the worldwide web at http:/ts.nist.gov/Standards/Conformity/upload/PS%201%20final%20complete%20w%20cover.pdf.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.3 explosion,na chemical reaction of any chemicalcompound(or mechanical mixture)that,when initiated,under-goes a very rapid combustion or decomposition releasing largevolumes of highly heated gases that exert pressure on thesurrounding medium.DOD 4145.26 M3.2.4 explosive,nany chemical compound(or mechanicalmixture)that,when subjected to heat,impact,friction,detonation,or other suitable initiation,undergoes a very rapidchemical change with the evolution of large volumes of highlyheated gases that exert pressures in the surrounding medium.DOD 4145.26 M3.2.5 fireball,na highly luminous,intensely hot cloud ofdust,gas,and or v
