1. A leak test arrangement (1) for testing a structural component (2) or a closed package/object (2″+21″, 2″*) having a wall to be tested for tightness, comprising:
a test chamber (3), in which the structural component (2) or the packaging/object (2″+21″, 2″*) is placed during the leak testing; a test gas space (4) which is formed on a first side of the wall of the structural component (2) and of the test chamber (3) or which corresponds to the interior of the package/of the object (2″, 2″); a testing space (5) which is formed on a second side of the wall of the structural component (2) and the test chamber (3) or is formed between the wall of the package/object (2″+21″, 2″*) and the test chamber (3); a test gas supply (6) for supplying compressed air (DL) and/or a test gas (TG) into the testing space (5); a test gas measuring arrangement (7) for measuring or detecting the test gas (TG) in the testing space (5) with a sensor system (72); a testing space vacuum arrangement (51) for evacuating the testing space (5); wherein the sensor system (72) comprises a mass spectrometer, a quadrupole mass spectrometer (72) and/or at least two single test gas sensors (721, 722), wherein the sensor system (72, 721, 722) of the test gas measuring arrangement (7) can detect at least two test gasses (TG I and TG II), the test gas supply (6) can be charged with at least two different test gases (TG I, TG II), wherein either the first test gas (TG I), the second test gas (TG II) or a combination of the first (TG I) and the second test gas (TG II) can be introduced into the test gas space (4) and a mixing arrangement (61) is provided upstream of the test gas space (4) for mixing the test gas(es) (TG I, TG II) with compressed air (DL), wherein the mixing arrangement (61) comprises means for the homogeneous mixture of the test gas (TG I, TG II) with the compressed air, and wherein the test gas supply (6) comprises at least three individual introduction means, which extend directly into the test gas space (4) or are located there, wherein a first introduction means is supplied with compressed air (DL), a second introduction means is supplied with a first test gas (TG I) and a third introduction means is supplied with a second test gas (TG II). |
