27、nce with the manufacturers writteninstructions subject to the requirements of Test Method E2639,paragraph 13.1.9. Test Method9.1 TestingThe trash receptacle test specimens shall betested according to the requirements of Test Method E2639.Each test specimen shall be tested separately from the others

28、inthe group submitted with the charge at one of three differentlocations. The testing laboratory shall randomly select theindividual test specimen for each test from the group submit-ted.9.1.1 Trash receptacles shall be tested as supplied by themanufacturer for in-use service. For example, if the tr

The lid shall be secured to the receptacleas recommended by the manufacturer.9.2 The Explosive ChargeThe mass of the explosivecharge shall be agreed upon between the manufacturer and thebuyer.NOTE 1In practi

30、ce, the buyer is expected to have knowledge of theforce protection level required of the trash receptacles being consideredfor purchase. Based on this knowledge, the manufacturer and buyer areexpected to discuss the availability of products meeting the required forceprotection level, which in turn w

31、ould lead to agreement on the mass ofcharge to be used in the testing.9.2.1 The mass of the explosive charge shall be the same forall test specimens in the group submitted.9.2.1.1 The force protection level of the trash receptaclespecimen group submitted shall be the numerical mass of theexplosive c

33、Bare Charge Test 1This test shall be conducted byplacing the explosive charge at location 2, as described in TestMethod E2639, paragraph 10.1.2 and Figures 1A and 1B.E2740 1029.3.3 Bare Charge Test 2This test shall be conducted byplacing the explosive charge at location 4, as described in TestMethod

34、 E2639, paragraphs 10.1.4 and 10.1.5 or 10.1.6, andFigures 1A, 1B, and 2.9.4 Testing LaboratoryTesting shall be performed at anindependent commercial or government explosive testing labo-ratory following conformance with applicable safety standardsand laws. The testing laboratory shall have all requ

35、ired licensesand permits for explosive testing.10. Performance Requirements10.1 Trash receptacle specimens conforming to this speci-fication shall meet the following performance requirements:10.1.1 Requirement Specific to the Fragmentation ChargeTest:10.1.1.1 There shall be no perforation of the ver

36、tical exte-rior wall of the trash receptacle test specimen from a primaryfragment. In addition, there shall be no perforation of silhou-ettes that are located 3 m (10 ft) and further from the center ofthe test platform.NOTE 2The requirement regarding no perforation of silhouetteslocated 3 m (10 ft)

37、and further from the center of the test platform is basedon considerations associated with existing technology and costs ofproducing trash receptacles that provide blast resistance. These productsmitigate the effects of an explosion; in general they are not vessels thatprovide total containment of a

38、n explosion.10.1.2 Requirements for Either Fragmentation or BareCharge Tests:10.1.2.1 The test specimen shall remain on the test platformand in the vertical position in which it was mounted or attachedprior to detonation.10.1.2.2 There shall be no release of metallic secondaryfragments from either t

39、he interior surfaces of the test specimenor from the exterior surfaces including the top of the testspecimen, as evidenced by examination of:(1) the witness panels, which shall show no impingementor perforation by metallic fragments,(2) the grounds within the 76 m (250 ft) diameter of the testarena,

40、 which shall show no metallic fragments due to theexplosion, and(3) the high speed photography, which shall show norelease of metallic fragments.10.1.2.3 There shall be no visible fissure in the outer surfaceof the trash receptacle specimen exterior wall that is eithergreater than 15 mm (0.6 in.) in

41、 width, or greater than 100 mm(4 in.) in length.10.1.2.4 There shall be no more than three separate visiblefissures of any size in the outer surface of the exterior wall.10.1.2.5 There shall be no direct opening from the exteriorto the interior of the test specimen, as evidenced by probing allvisibl

42、e fissures in the exterior wall with a round, straight 4 mm(316 in.) steel rod. A direct opening is present if the steel rodpenetrates all the way through from the exterior to the interiorof the specimen.10.2 BulgingBulging of the exterior wall of a test speci-men that conforms to the requirements i

43、n 10.1.1 and 10.1.2does not constitute failure.10.3 Pressure Data:10.3.1 Pressure data shall be collected in accordance withTest Method E2639 and recorded in the testing laboratoryreport. Pressure data are not used as the basis of a performancerequirement of this standard specification. Pressure dat

44、a maybe useful when considering alternative locations for placementof trash receptacles in service.10.3.2 See Appendix X1 for a discussion of pressure data.11. Product Marking11.1 Each trash receptacle shall be marked with the manu-facturers name and contact information, and with a uniqueserial numb

45、er, unless otherwise agreed upon by the manufac-turer and buyer. The serial number shall be marked in a durablemanner, such as with a metallic plate riveted to the trashreceptacle.NOTE 3For security purposes force protection levels of trash recep-tacles meeting this standard specification are not pr

46、ovided in publiclydisseminated marketing materials or marked on units sold commercially.12.

47、 Information)X1. COLLECTION OF PRESSURE DATAX1.1 IntroductionX1.1.1 The referenced ASTM Test Method requires thecollection of pressure data. However, this specification doesnot contain performance requirements associated with thepressure data. The primary use for the pressure data is to assistin det

48、ermining proper in service placement. There are tworeasons that performance requirements are not placed on thepressure field recorded during the test. Both are based on datafor the lethality of blast pressures and impulses. In the first, thedistances for 90 % and 99 % survivability of blasts in free

49、 airare calculated. In the second, data collected from tests ofcommercially available trash receptacles which are advertisedas blast resistant are examined. Finally, an overall discussion isoffered.X1.2 Test DataX1.2.1 In 2005, the Naval Explosive Ordnance DisposalTechnology Division tested eleven commercially availabletrash receptacles that are sold as blast resistant. All tests wereE2740 103conducted in an open arena. It is likely that the test resultswould have differed widely if the tests were conducted in anenclosed structure. The results are
