Largely defined by the maximum explosion temperature. The maximum explosion overpressure, P max, is the difference between the pressure at the time of ignition and that at the highest pressure attained in the dynamic pressure curve during a dust explosion. Maximum rate of pressure rise or d P d t max: Generally measured from initial condition.
