Up to now civil used explosives were characterized by describing their original state before ignition and their end products after detonation and also by describing their physical properties, e.g. the velocity of detonation. The dynamics of detonation in the civil sector is barely investigated whereas in the military field the explosives are thoroughly described. For this a so-called cylinder test is used, which take advantage of a time-depended measurement method for describing the explosives. The explosive is filled in a copper cylinder and initiated by a booster. The expansion of the cylinder is measured during the detonation as a function of time. The Gurney energy is evaluate by the radial expansion of the copper tube over the time.
