An apparatus for testing articles such as can ends and the like is described. A lid for a can is placed to cover a pressurizable test chamber in a lower platen. An upper platen is brought down over the lid to firmly clamp the lid against the test chamber and submerge the platens below the surface of a body of liquid such as water. The upper platen is provided with a gas bubble capturing chamber to prevent gas bubbles trapped in and about the submerged structure from interfering with the observation of articles through ports in the upper platen. A transparent liquid damper is employed over the upper platen and is selectively spaced to be partially submerged in the liquid over the viewing ports for clear viewing of articles under test.
