The invention discloses an explosion impulse and pneumatic pressure load combined testing comprising a pressure bearing plate 1, a pressure transmission rod 2, a sensor 3, a fixed bolt 4, a test wire5 and a fixed frame 6; the pressure bearing plate 1 is a rectangular steel plate, and flush with an opening plane of the fixed frame 6; one end of the sensor 3 is fixedly connected with the pressure bearing plate 1 through the pressure transmission rod 2, and the other end is arranged on the fixed frame 6 through the fixed bolt 4; the test wire 5 outputs test signals of the sensor 3. The one set of device can simultaneously test the shock wave impulse load and the pneumatic pressure load, thus solving the impulse load and the pneumatic pressure load dynamic testing problems, providing technical supports for the ammunition damage explosive strength tests and assessments, reducing testing workloads, and reducing test costs.
