A process and device are disclosed for testing the tightness of hollow bodies by means of a test gas. For that purpose, the hollow body is subjected to a differential pressure, so that the gas may stream towards the side of the lower pressure when the hollow body is not tight. The particular advantage of this process is that air may be used as test gas, which according to the test specifications may be decomposed into a test gas portion and a venting portion. |
