The Stab Tester is a self-supporting structure that permits the testing of soft and hard body armour to be evaluated to the stab standards of the National Institute of Justice (NIJ) and the Home Office Scientific Development Branch (HOSDB). This system can test samples up to an energy of 90 J using a wide assortment of threat simulators. The custom designed software will indicate the necessary drop height and will calculate the impact energy upon completion of the test.
