Military Explosives Chapter 12

Explosives are classified as low or high explosives accord-ing to their rates of decomposition. Low explosives burn rapidly (or deflagrate). High explosives ordinarily deton-ate. There is no sharp line of demarcation between low and high explosives. The chemical decomposition of an explosive may take years, days, hours, or a fraction of a second.
