Critical Diameter of
Energetic Material

The critical diameter determination of any explosive formulation or commercial product is of utmost importance. This test establishes the minimum physical size a charge of a specific explosive must be to sustain its own detonation wave. The procedure involves the detonation of a series of charges of different diameters until difficulty in detonation wave propagation is observed. This is to ensure confidence and reliability that the explosive will perform under all conditions as it was intended upon manufacture.

UTEC routinely performs this crucial test under end user defined conditions as well as identifying and recommending the best parameters for a particular products end use within the industry.
