The invention relates to an improved method for testing a leak detector by means of a test leak device (10), which is provided with a test leak (16) and which has a cavity (12) that can be filled with gas. The method is characterized by the following steps: a) filling the cavity (12) with ambient air up to an internal pressure (P1) inside the cavity (12) that corresponds to atmospheric ambient pressure, b) producing an external pressure (P2) in the region surrounding the test leak device (10), said external pressure being lower than the internal pressure (P1), c) measuring the leak rate of the air flowing through the test leak device (10) from the inside out through the test leak (16), and d) producing an atmosphere composed of ambient air and having atmospheric ambient pressure as the external pressure (P2) in the region surrounding the test leak device (10). |
