Fundamental jet performance tests of linear shaped charges (LSC) were conducted to evaluate their jet penetration behavior. The criteria used for these tests were based on penetration tests for conical shaped charges (CSC). Photos of the aluminum-sheathed LSC jet taken by using flash X-ray confirmed the jet velocities to be about 2,400 m·s-1. The steel plate penetration tests uses steel plates, insulated sheets, a pulse generator and a digital oscilloscope. The penetration velocities of aluminum- and lead-sheathed LSC against steel plates were calculated to be less than 1,000 m·s-1 at a maximum region. These proposed testing methods are very useful for improving the performance of LSC.
