Claim:
1. A method for testing a leakage detection system using a test leak device that is located in a test chamber of the leakage detection system, wherein the test leak device is provided with a test leak and has a cavity that can be filled with a gas, having the steps: a) filling the cavity of the test leak device with ambient air until an interior pressure in the interior of the cavity corresponds to ambient atmospheric pressure, b) establishing an exterior pressure in the test chamber in the area surrounding the test leak device that is lower than the interior pressure in the cavity, c) measuring of the leakage rate of the air flowing from the cavity into the test chamber through the test leak of the test leak device, and d) establishing an exterior pressure in the test chamber in the area surrounding the test leak device using an atmosphere consisting of ambient air with an ambient atmospheric pressure.
