Abstract

Abstract: According to the standard “Explosive Test Method”, the test for shock sensitivity of explosives is much consumptive, inconvenient, and the results are affected by personal factors easily. Combining small cardboard test with underwater explosion experiment, an underwater cardboard test method for shock sensitivity was proposed, which could be much safer, less consumptive, environment-friendly and fairly worthwhile. The underwater explosion device, components and materials, test system, operation procedure and data processing of the experiment method were also given. Five common explosives, including TNT, were tested. The results show that the new method can acquire abundant information, needs only less samples, and has better accuracy. It can be used for test of high sensitivity explosives, and can be carried out under general experiment circumstance.

Key words: mechanics of explosion, high sensitivity explosive, underwater explosion, shock sensitivity, small cardboard test
