Definitive conclusions about high and low order reactions can be drawn from individual framing‐mode pictures of a rotating mirror camera record, when both the vellocity of the axial propagation of the reaction along the outer contour and the velocity of radial expansion of the reaction products are analysed at various distances from the plane of initiation. In this, the intensity of the reaction can be assessed quantitatively from the radial expansion velocites, even when, for example, a penetrating shaped charge jet induces an axial drag wave in the test charge. A detailed description is given of the test set‐up and of the test results obtained with charges exposed to the impact of a shaped charge jet.
