Abstract
The present invention is directed to a method of leak testing a container with a flexible wall portion. The container is introduced into a test cavity so that the flexible wall portion and an adjacent wall portion of the cavity form an intermediate space. A pressure difference is applied from the inside of the container into the space and a signal, dependent on the pressure difference is evaluated as a leak indicative signal, and wherein bending outwards of the flexible wall portion of the container is stabilized by at least one abutment surface in the space. The invention is further directed to a test chamber suitable for use in the method.
