The Maximum Explosion Pressure (Pmax) characterizes the destructive force of a dust explosion. It is the maximum overpressure exerted on the inner wall of a container when the dust explodes at various concentrations. The Explosion Index (KSt) is the maximum rate of pressure rise per unit volume. Together, these two parameters serve as fundamental data for the design of explosion venting, explosion isolation, explosion suppression, and explosion-resistant containment.
