In order to study the explosive safety under heat and bullet impacting multiple environment，the mode of adding heating system on the base of bullet impacting test was used to simulate multiple effect. The multiple environment tests for PBX2 of 150 long with a diameter of 75mm were made. The processes of temperature changing for different positions in the sample were measured by use of thermocouples, and the reaction degree of different size explosives was analyzed by the measurement of shockwave overpressure. The reaction characteristics for PBX2 were gained under heat and bullet impacting multiple environment. The results show that reaction degree for PBX2 is essential accord under multiple test,the test method can provide a new means to evaluate explosive safety under exceptional environment.
