An experimental program was conducted to establish the sensitivity of molten and solid Amatex to impact by non-spinning, primary steel fragments weighing 14 to 42 grams 0.5 to 1.5 oz and traveling at velocities of 533 to 2, 105 msec 1, 748 to 6,907 fps. Parameters that were varied included the absence or presence of steel acceptor plates of different thicknesses, fragment mass per unit impact area and the molten vs solid physical state of the Amatex. Results of this program indicate that molten Amatex charges are significantly more sensitive to fragment impact than solid Amatex charges. Molten Amatex is also more sensitive than molten Composition B while solid Composition B is more sensitive to fragment impact than solid Amatex. In addition, it appears that a relationship exists between the kinetic energy of the fragment, its impact area and the threshold detonation velocity.
