Abstract:
A method for leak testing at least one closed and filled container, whereby the content of said container comprises at least one liquid component and wherein a pressure difference is applied across at least a part of the wall of the container, which part is to be tested, said pressure difference being directed towards the surrounding of said container and wherein the pressure in said surrounding is monitored as a leak indicative signal, further comprising that siad pressure difference is established by lowering said pressure in said surrounding and further comprising the step of comparing a signal derived from said pressure monitored with a dynamic threshold value for identifying leak condition of said container and enabling a further signal derived from said pressure monitored to be averaged with similar further signals of other containers previously tested as unleaky if said identifying of the container now under test reveals an unleaky container and further deriving said threshold value from the result of said averaging.
