Impact Sensitivity
15 mm length; 19 g) and varying their velocity. They are accelerated in
a gun by means of compressed air or gunpowders. The front of them
is plane, the back concave for better flight stability. A pendulum bearing
a shock acceptance plate, hanging at about one yard from the
shooting line, and the observation of the appearance of light and of
smell are used to determine reaction of the explosive sample.
