Is gunpowder considered an explosive?

Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn) at subsonic speeds, whereas high explosives detonate producing a supersonic shockwave.

Is black powder explosive?
