This paper presents a design process of ballistic chamber for certification tests of crushers, including all design’s steps from conceptual design to shooting tests. This issue has been raised, because so far, all certification tests were carried out only by shooting tests, which was associated with high costs and large amount of effort. Therefore design of ballistic chamber for certification tests of crushers was aimed at reducing costs, including the reduction of the amount of necessary equipment. Design process of ballistic chamber for certification tests of crushers consists of a few steps, which were thoroughly described in the article. In the first step basic parameters of the ballistic chamber was calculated and in the second step, based on obtained results, 100 mm BS-3 barrel gun was adapted to carrying certification tests of crushers. In the third step the charge was fired in the ballistic chamber and the pressure graph was obtained. Next the pressure graphs from the ballistic chamber have been compared to analogous pressure graphs from the 100 mm BS-3 barrel gun (in which certification tests of crushers were usually carried out). Comparison has shown that the ballistic chamber can be used for certification tests of crushers and also for the ballistic tests of charges in the dynamic conditions, as in real shooting process.
