Explanation

Under the direct action of primary explosive, booster explosive or other heavy explosives. The degree of difficulty of detonation of explosive, also known as detonation sensitivity. Generally, it is expressed by the minimum initial charge (limit charge), which refers to the minimum initial charge required to fully detonation the heavy explosive under certain test conditions. The smaller this amount is, the higher the detonation sensitivity of the heavy explosive is. The minimum amount of primary explosive is also related to the test conditions (such as explosive particle size and density of charge, etc.). The minimum detonating charge is also used to measure the detonating ability of primary explosive. The smaller the value, the greater the detonating ability of primary explosive.
