ABSTRACT:
A vessel for holding the atmosphere in which a test piece is tested has a test atmosphere chamber and an auxiliary chamber intercommunicably formed in a casing and a piston disposed freely slidably in the casing with the upper portion inside the auxiliary chamber and the lower portion protruding into the test atmosphere chamber. A test piece has one end thereof connected to the lower portion of the piston and the other end thereof fastened to a stay fixed in the test atmosphere chamber. A test gas is introduced under pressure into the test atmosphere chamber. The interior of the test atmosphere chamber and that of the auxiliary chamber are placed under an identical pressure. The surface areas of the piston are equal so that the strength of the test piece under a specific atmospheric condition can be accurately measured without subjecting the loading shaft to the otherwise possible effect of the pressure of the test atmosphere.
