What is the detonation velocity range considered low?

The detonation velocity range that is classified as low is defined by values from 400 to 1,300 feet per second (FPS). This range indicates the speed at which the shock wave travels through an explosive material during detonation, and it is generally associated with less powerful and slower explosives compared to those with higher detonation velocities.

Explosives in this low range are typically classified as deflagrants or low-order explosives, which tend to burn rather than detonate. Their lower detonation velocities result in a different behavior when used in applications, influencing their effectiveness and suitability for specific engineering tasks. Understanding these velocities is crucial in applications such as demolition, where the characteristics of the explosive can impact the safety and effectiveness of the operation.
