PCT No. PCT/CH86/00121 Sec. 371 Date May 4, 1987 Sec. 102(e) Date May 4, 1987 PCT Filed Aug. 26, 1986 PCT Pub. No. WO87/01449 PCT Pub. Date Mar. 12, 1987.The test device (7) serves in particular for testing bottle-shaped containers (4), and is in the form of a piston/cylinder assembly. It has two pistons (41, 53) in order to test simultaneously or consecutively two properties of the container (4), while the position of the container (4) and cylinders (30, 31) remains the same. The two pistons (41, 53) can be operationally connected by a piston rod (42). The piston strokes are different. Containers which are to be filled with a liquid material and are preferably made of plastic can be tested in this way before they are filled with the material thus making it possible to locate quickly and unambiguously any containers which are to be rejected owing to their dimensions, resistance to crushing, sealing property and so on, before the filling process takes place.
