摘要： The invention relates to a device for leak detection on a test specimen, having an evacuable test chamber for the test specimen. 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.

摘要： The invention relates to a test device for carrying out load tests on flexible, elongated test objects, including a first suspension which is movably guided along a closed circulating path for a first end of the test object, a drive for moving the first suspension along the path, a second suspension for fastening another end of the test object, and a mass body that can be attached to the test object between the two suspensions in such a manner that the mass body is movable along the test object.

摘要： A method for leak detection of a test specimen includes providing an evacuable film test chamber which is operatively coupled to a pressure measuring device, and at least one processor operatively coupled to the pressure measuring device; measuring a pressure within the evacuable film test chamber by the pressure measuring device at predetermined times during a measurement period of time; calculating by the processor, a first or higher order derivative of a pressure change with respect to time at a first predetermined time, and a first or higher order derivative of a pressure change with respect to time at least at a second predetermined time during the measurement period of time, to provide at least a pair of derivative values; and categorizing by the processor a leaky or tight state of the specimen under test by a pattern recognition process based on the pair of derivative values.
