A device for evacuating a film chamber using a pump system that comprises at least two vacuum pumps, designed to evacuate the film chamber alternately. A suction capacity of the first vacuum pump is greater than that of the second vacuum pump and the final pressure achievable by the first vacuum pump is less than that of the second vacuum pump.

Evacuation of a film chamber

The invention relates to a film chamber for receiving a test object to be tested for the presence of a leak, including at least two film layers and at least two frame elements, each of which has a sealing surface so that the two frame elements lie against each other in a gas-tight manner in order to hermetically seal the film chamber. Each of the two film layers has at least one retaining profile in a wall region, and each of the two frame elements has at least one retaining groove in the frame element sealing surface in order to receive a retaining profile such that the two film layers are held between the two frame elements substantially by a formfitting connection.

Film chamber with retaining profile

A method for testing a leak detector by using a leak detection device having a test leak and which is provided with a cavity that can be filled with gas, including the following steps:

Method for testing a leakage detection system

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.
