摘要

This paper deals with high explosive projectile reproduction process over several years of monitoring and testing its fragmentation characteristics. Experimental data used in analy-sis were obtained using PIT tests in our country.Many fragmentation tests were conducted with 19 different production series of projectile mortar projectile 120mm M62, in a time span of over three years.Number, mass and fragments shape of each fragment mass group are determined using the PIT test. In PIT test, warhead is detonated in closed space, filled with sand. After the fragmentation of warhead, fragments are obtained from the sand. Mass and shape of fragments are determined, and fragments are classified by their mass groups. Number of methods is available for prediction of fragment mass distribution, and one of these is method introduced by M. Held.Authors tried to find variations in reproduction process of projectile, using statistical pa-rameters of given tests.In order to analyze possible significant differences between tests, Student t-test was intro-duced.
