29、rs (gallons) along with desiredfinishes and other requirements associated with the physicalattributes of the trash receptacle.5. Materials and Manufacture5.1 The materials and method of manufacture shall be at thediscretion of the manufacturer sufficient to meet the perfor-mance requirements of this
30、 specification.6. Workmanship6.1 The trash receptacles shall have no defects that willadversely affect their service qualities.7. Number of Tests and Retests7.1 Test SpecimensEach explosive test shall be performedon a new, undamaged trash receptacle.7.2 Number of Test SpecimensThe minimum number oft
31、est specimens submitted for each force protection level testshall be three. The manufacturer shall provide all three testspecimens at one time.7.3 RetestsOnly one retest is allowed per group of sub-mitted test specimens.7.3.1 If upon testing, one of the trash receptacle specimensin the group submitt
32、ed does not meet the requirements of thisspecification, the manufacturer shall provide a new specimenfor retesting.7.3.1.1 If this retest specimen does not meet the require-ments of this specification, the entire force protection levelgroup of specimens including test specimens that may or maynot ha
33、ve been tested shall be rejected. The group shall beE2740 1212considered not to meet the requirements of this specification.The manufacturer shall provide three new specimens forretesting.7.3.2 If upon testing, two or more trash receptacle speci-mens in the group submitted do not meet the requiremen

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 inthe group submitted with the charge at one of three differentlocations. Th
36、e testing laboratory shall randomly select theindividual test specimen for each test from the group submit-ted.9.1.1 Trash receptacles including accessory componentsshall be tested as supplied by the manufacturer for in-useservice. For example, if the trash receptacle is intended to havea lid in ser
37、vice, it shall be tested with the lid in place. The lidshall be secured to the receptacle as recommended by themanufacturer.9.1.1.1 Typical trash receptacle accessory components sup-plied by manufacturers for in-use service include lids, trashreceptacle liners, and trash receptacle rubbish bags.9.2
38、The Explosive ChargeThe mass of the explosivecharge shall be agreed upon between the manufacturer and thebuyer.NOTE 1In practice, the buyer is expected to have knowledge of theforce protection level required of the trash receptacles being consideredfor purchase. Based on this knowledge, the manufact
39、urer and buyer areexpected to discuss the availability of products meeting the required forceprotection level, which in turn would 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.
