ABSTRACT:
A method and apparatus for leak testing a first and a second cavity of a part. A fixture is provided for engaging and individually sealing the cavities of the part. Pressurized fluid from a pressure source is introduced into each of the cavities. The first cavity is allowed to stabilize and its leak rate is measured using a pressure-measuring device. The first cavity is then vented. Upon stabilization of the second cavity, the leak rate thereof is similarly measured. The second cavity is then also vented. The leak rates are then evaluated to determine if a leak is present in either of the cavities.
