Abstract: The work is statistically substantiated by the use of methods of qualimetry for assessing the quality of materials in conditions of high-speed loads. The results of theoretical and statistical researches concerning estimation of quality level of speed-loaded metal materials with the help of methods of qualimetry are given. It is established that in order to increase the reliability of their evaluation, it is necessary to propose acceptable qualitative characteristics of metal materials, which, in the case of quality evaluation in conditions of high-speed loads, are represented by dynamic parameters. The following material parameters are defined such as: loading speed, longitudinal and transverse shear rates, along with the deformation rate and the strength of the slit, are critical in assessing the quality level of loaded materials, since they are least varied in the area of loading of metal materials. The mathematical calculation of statistical data presented in the form of dynamic characteristics of loaded materials is proposed. It is established that the mean square deviation of statistical data is within the limits of the permissible variation coefficient. It is shown that increasing the reliability of the assessment of the quality of materials is permissible due to some adaptation of the methods of qualimetry due to the specific conditions in which the studied list of metal materials works.
