【 摘 要 】

There are many factors which affect the performance of a drum closure during drop tests. Important test conditions are: weight of package, height of drop, and angle of impact. Structural characteristics of the package determine its ability to withstand the test conditions imposed. These characteristics include: package diameter, shell material and thickness, strength of internal fill material (e.g., fiberboard), and configuration of closure (clamp-ring, bolted flange, etc.). For the clamp-ring closure configuration a study of published drop test results has shown that packages having a weight ratio of less than 50 per cent were typically able to retain their lids in hypothetical accident condition, 30-ft drop tests. Those having weight ratios greater than 50 per cent typically failed. Prior testing over the integrity of the clamp-ring closure, consistently demonstrated that the clamp-ring is unable to retain the drum lid in thirty foot drop tests of packages containing the maximum allowed weight (640 lb), which confirms the previous studies. To determine if the clamp-ring closure is adequate for packages with lower weight contents, a series of tests were performed on packages weighing around 325 lb (i.e., a typical shipping weight for DOE packages) at a range of impact angles as detailed in this report. The test results consistently demonstrated that the standard clamp-ring closure is unable to retain the drum lid of standard 6M packages weighing 325 lb.
