ABSTRACT:
A tester for testing the strength (wall stiffness) of a tubular sleeve applies axial pressure to the sleeve via a pair of sealing platens closing the open ends of the sleeve and holding the sleeve in the desired configuration. With the sleeve so held air pressure is applied to the inside of the sleeve and the deflection of at least one of the walls is measured and correlated with the applied air pressure applied thereby to obtain an indication of the strength and stiffness characteristics of the container. Generally with a rectangular cross section sleeve deflection of all four sides of the sleeve are measured.
