The aim of the paper is to show a type of the round-Robin test on the example of experiments at a high strain rate using various split Hopkinson pressure bar test stands located at different locations in Warsaw – a scientific-technical center and a university. The results of the conducted experiments in the form of a circumferential stress and radial stress were shown for each analyzed SHPB test stand, using an identical research specimen. A comparison was made, and the obtained results were compared on the graphs of the stress-strain curve for various SHPB test stands and on the strain rate – strain graphs for the selected SHPB test stand.
