Measuring the blast contour method of the horizontal displacement of momentum gauges made of cylinders with 70 rum diameter and 50 mm, respectively 100 mm length or rectangular cross section of 25 mm width and 50 mm height with the Held momentum method gives very well corresponding results with regard to the measured impulse densities in the four selected radii of 0.25 m, 0.5 m, 0.75 m and 1.00 m. This confirms the validity of the selected test method.
