To cooperate the identification and evaluation of suspected hazardous materials for public security department, the national standards including "Guidelines for physical hazard testing of chemicals" and "GB/T13226-1991 lead plate test for industrial detonator" issued by country were systematically applied to the identification and evaluation of explosiveness test for hazardous materials. Among them, the UN gap test 1(a), Koenen test 1(b) and time/pressure test 1(c) were applied to identify whether the hazardous materials had explosiveness or not. The cap sensitivity test 5(a) was applied to determine the sensitivity of hazardous materials on strong mechanical stimulation. The lead plate test was applied to identify whether the electric detonator, safety fuse and flash detonator had explosiveness or not. With above-mentioned test methods, the identification and evaluation of combustibility or explosiveness for hazardous materials including ammonium nitrate (AN), ammonium perchlorate (AP), suspected black powder, fuse, suspected AN explosive, suspected electric detonator and flash detonator obtained from public security department were performed. Results show that the AN can not be initiated with industrial detonator, while the AP and AP/AN mixture have explosiveness and can be initiated with industrial detonator, the effectiveness of the identification and evaluation standard of the explosiveness test is verified. Whether or not suspected AN explosive has explosiveness can be identified using UN gap test 1(a). Whether or not suspected black powders and safety fuse have combustibility can be qualitatively identified using combustion test. Whether or not suspected electric and flash detonators have explosiveness can be identified using lead plate test.
