The impact sensitivity,friction sensitivity,thermal sensitivity (explosion point) and sensitivity to electrostatic spark of HNIW were measured according to the Chinese National Military Standard (GJB). The obtained results are as follows： H₅₀=20～27cm (5kg hammer); friction sensitivity 100% (90±1°，3.92±0.07MPa) or 92% (80±1°，2.45±0.07MPa)，explosion point 283.9℃(5s delay time); V₅₀=4.61kV，E₅₀=0.106J.
