The goal of theoretical research is to establish parameters, which have to be given in standards for percussive tests of products. Those parameters are essential for each user to be able to construct identical (equivalent) testing equipment. This would ensure identical results for identical products. The paper presents a detailed analysis of the distribution and the value of the forces generated during percussive collisions of two bodies. Elastic, plastic, and elastoplastic collisions are considered. Parameters determining the coefficient of restitution, the courses of energy, momenta, and the values of the forces in colliding elements are determined. The dynamic force acting on a product during a percussive test was studied.
