Number of Tests and Retests7.1 Test SpecimensEach explosive test shall be performed on a new, undamaged trash receptacle.7.2 Num
33、ber of Test SpecimensThe minimum number of test specimens submitted for each force protection level test shall bethree. The manufacturer shall provide all three test specimens at one time.7.3 RetestsOnly one retest is allowed per group of submitted test specimens.7.3.1 If upon testing, one of the tr

35、ncluding test specimens that may or may not have been tested shall be rejected. The group shall be considered not tomeet the requirements of this specification. The manufacturer shall provide three new specimens for retesting.7.3.2 If upon testing, two or more trash receptacle specimens in the group
36、 submitted do not meet the requirements of thisspecification, the manufacturer shall provide three new specimens, all of which shall be subject to retesting.8. Specimen Mounting8.1 The trash receptacle test specimen shall be placed on the test platform in accordance with the manufacturers writtenins
37、tructions subject to the requirements of Test Method E2639, paragraph 13.1.9. Test Method9.1 TestingThe trash receptacle test specimens shall be tested according to the requirements of Test Method E2639. Each testspecimen shall be tested separately from the others in the group submitted with the cha
38、rge at one of three different locations. Thetesting laboratory shall randomly select the individual test specimen for each test from the group submitted.9.1.1Trash receptacles shall be tested as supplied by the manufacturer for in-use service. For example, if the trash receptacle isintended to have
39、a lid in service, it shall be tested with the lid in place. The lid shall be secured to the receptacle as recommendedby the manufacturer.9.1.1 Trash receptacles including accessory components shall be tested as supplied by the manufacturer for in-use service. Forexample, if the trash receptacle is i
40、ntended to have a lid in service, it shall be tested with the lid in place. The lid shall be securedto the receptacle as recommended by the manufacturer.9.1.1.1 Typical trash receptacle accessory components supplied by manufacturers for in-use service include lids, trash receptacleliners, and trash
41、receptacle rubbish bags.9.2 The Explosive ChargeThe mass of the explosive charge shall be agreed upon between the manufacturer and the buyer.NOTE 1In practice, the buyer is expected to have knowledge of the force protection level required of the trash receptacles being considered forpurchase. Based
42、on this knowledge, the manufacturer and buyer are expected to discuss the availability of products meeting the required force protectionlevel, which in turn would lead to agreement on the mass of charge to be used in the testing.9.2.1 The mass of the explosive charge shall be the same for all test s
43、pecimens in the group submitted.9.2.1.1 The force protection level of the trash receptacle specimen group submitted shall be the numerical mass of the explosivecharge expressed in kilograms (pounds) of TNT.9.3 Explosive Charge Locations (for purposes of this specification):9.3.1 Fragmentation Charge
44、 TestThis test shall be conducted by placing the explosive charge at location 1, as described inTest Method E2639, paragraph 10.1.1 and Figures 1A and 1B.9.3.2 Bare Charge Test 1This test shall be conducted by placing the explosive charge at location 2, as described in TestMethod E2639, paragraph 10
45、.1.2 and Figures 1A and 1B.9.3.3 Bare Charge Test 2This test shall be conducted by placing the explosive charge at location 4, as described in TestMethod E2639, paragraphs 10.1.4 and 10.1.5 or 10.1.6, and Figures 1A, 1B, and 2.9.4 Testing LaboratoryTesting shall be performed at an independent commer

47、meet the following performance requirements:10.1.1 Requirement Specific to the Fragmentation Charge Test:10.1.1.1 There shall be no perforation of the vertical exterior wall of the trash receptacle test specimen from a primary fragment.In addition, there shall be no perforation of silhouettes that a
48、re located 3 m (10 ft) and further from the center of the test platform.NOTE 2The requirement regarding no perforation of silhouettes located 3 m (10 ft) and further from the center of the test platform is based onconsiderations associated with existing technology and costs of producing trash recept
49、acles that provide blast resistance. These products mitigate theeffects of an explosion; in general they are not vessels that provide total containment of an explosion.10.1.2 Requirements for Either Fragmentation or Bare Charge Tests:10.1.2.1 The test specimen shall remain on the test platform and in the vertical position in which it was mounted or attachedprior to detonation.E2740 12310.1.2.2 There shall be no release of metallic secondary fragments from either the interior surfaces of the test specimen or fromthe exterior surfaces incl
