Abstract (en)
[origin: WO2013072173A2] The invention relates to a device for leak detection on a test specimen 12, having an evacuable test chamber 14 for the test specimen 12. The test chamber is provided with at least one wall area made of a flexible, in particular elastic material. For more precise leakage detection, the progression of the total pressure increase inside the test chamber is measured.
