ABSTRACT:
A method and apparatus for leak testing a hollow body wherein the hollow body is placed in a test chamber. The hollow body is exposed to one of a positive or negative differential pressure between an internal pressure of the hollow body and a pressure in the test chamber. A pressure prevailing in the test chamber is tapped off from the test chamber at two points in time, with a signal being generated of a pressure differential between the values of the prevailing pressure in the test chamber at the two points of time. The tightness or change in volume of the hollow body is determined in dependence upon the generated pressure differential signal.
