The appearance on the Polish market of new and innovative propellant devices, difficult to classify in accordance withthe Act on weapons and ammunition, drives the need for a continuous process of assessing their threat to human life and health.This is related to the lack of measurable tools for assessing the impact of the use of such devices. Research on this topic is beingundertaken by a group of scientists and partner research centres who have formed a consortium and have won funding throughthe competition for research and development in relation to national defence and security announced by the National Centre forResearch and Development (NCRD). The consortium has created a development project entitled Velocity testing of lowenergy projectiles. The project is led by the Police Central Forensic Laboratory in Warsaw, and also includes the PoliceAcademy, Szczytno, the Military Institute of Armament Technology, Zielonka, the Institute of Security Technologies “Moratex”,Łódź, and the Research and Development Centre of Research and Didactic Equipment COBRABiD Ltd., Warsaw. The aim of thisproject is to develop a special device for measuring the velocity of low energy projectiles, to conduct velocity tests and ricochettests on the most commonly occurring low energy projectiles, as well as to provide an assessment of their impact on humanbody. Preparation of the test bench prototype for measuring velocity of low energy projectiles, and the development of researchmethodology adequate for the diagnostic equipment used, will enable ballistics experts and other potential buyers and usersto thoroughly evaluate the trajectory of a projectile, energy at the point of impact, and to assess the effects of hitting a selectedtarget. The authors discuss the project objectives and present the partial results of the studies conducted so far, focusing on the tasksplanned for implementation by the Police Academy, Szczytno.
