Abstract
A leak detection method using a specimen filled with a test gas positioned in front of a suction opening. Air is suctioned along the entire surface of the specimen and takes up test gas in the case of a leak. The test gas is recognized by a test gas detector. According to the invention, full mobility of the specimen is ensured during the testing process so that the leak detection method can be carried out while the specimens are moving past the suction opening.
