Abstract
A method for conducting an integrity test on a flexible test container () includes arranging the test container () in an examination container () that is sealable in a fluid-tight manner, providing negative pressure in the interior of the sealed examination container (), filling examination fluid into the test container () arranged in the examination container (), detecting examination fluid present in the interior of the examination container (), and providing negative pressure in the test container () arranged in the examination container () prior to filling the examination fluid. Prior to filling the examination fluid, the negative pressure in the test container () is lower than the negative pressure in the interior of the examination container (), and the pressure difference between the negative pressure in the test container () and the negative pressure in the interior of the sealed examination container () is more than 0 mbar and a maximum of 100 mbar.
