撞击感度，炸药（火药）的一种属性，即在一定的冲撞下，炸药或火药发生爆炸或燃烧的程度。一般采用撞击感度仪测得。

量测数据一般为 x%(ykg,zm)，意义为质量y千克的落锤在z米落下时炸药爆炸率为x% 。

Shock sensitivity is a comparative measure of the sensitivity to sudden compression (by impact or blast) of an explosive chemical compound. Determination of the shock sensitivity of a material intended for practical use is one important aspect of safety testing of explosives. A variety of tests and indices are in use, of which one of the more common is the Rotter Impact Test with results expressed as FoI (Figure of Insensitivity.) At least four other impact tests are in common use, while various "gap tests" are used to measure sensitivity to blast shock. Julius-Peters KG is a notable German company which manufactures testing apparatus for these tests.
