ABSTRACT:
Device for testing the imperviousness of a flexible membrane (8) used for communications between the outside world and a volume (2) closed by a wall (1). The membrane is seal-connected to a movable box (13), the contents of which may be evacuated. Evolution of the pressure or the concentration of a gas derived from the volume (2) in the box (13) makes it possible to measure any leaks through the membrane (8).
