Metrological Aspects of Forensic Ballistic Reserch

Introduction. Conducting forensic ballistic investigations often involve changes to the results of which depend on the findings in many ways. According to local legislation, these measurements must meet certain requirements. Theoretical analysis. Analyzed compliance with the diagnostic techniques of forensic ballistic investigations homemade firing device for assigning it to firearms requirements of the Federal Law «On ensuring the uniformity of measurements». It is shown that the existing methodology is flawed, since it is in contradiction with the current metrological rules are not determined by random and systematic errors. Conclusions. It is proposed to either abandon the statistical processing of the measurement results and not to use the concept of the mean value, or increase the number of measurements for correct statistical treatment of results.
