ABSTRACT:
To test a closed container having at least one flexible wall area in order to determine a leakage by an increasing of the inner volume of the container and a measuring of a correspondingly caused changed measured value, at least one outer wall area of the container is exposed to a medium having a pressure which is greater than a pressure produced by the increase of the volume of the container if such has no leakage. The increase of the volume can be made by a pneumatic or mechanical application of a force at a flexible wall area. The arrangement is specifically suitable when the wall of the container or its contents strive to self-seal a leakage spot in a wall area.
