Abstract
The leaky or non-leaky condition of a flexible, closed container is tested by increasing the pressure within the container (by causing motion of a wall of the container), and monitoring the resulting rate of change of a predetermined parameter (wall position or force exerted by the wall); the monitored rate of change indicates the leaky or non-leaky condition. In another aspect the time-varying net force on a container is the basis for determining the leaky or non-leaky condition.
