High explosives detonate at what rate?

High explosives are characterized by their ability to detonate and produce a shock wave at a velocity that exceeds the speed of sound in air, typically at rates of at least 3300 meters per second, which is where the threshold for being classified as high explosives lies. This high detonation rate is essential for creating the immense pressure and temperature needed to cause significant destructive effects.

The classification of an explosive as a high explosive relies on this measurement, as the speed of detonation is a key determinant of its effectiveness in various applications, including military, demolition, and industrial uses. Explosives that detonate at rates below this threshold fall into the category of low explosives, which usually deflagrate rather than detonate, meaning they burn at a slower rate and do not create the same level of shockwave or destructive force.

Understanding these rates and classifications is crucial for law enforcement and emergency responders dealing with explosives, as it influences safety protocols and responses to incidents involving explosive materials.
