摘要： A method for performing a leak-tightness test on a test object (16) in a foil chamber (10) which has at least one flexible wall region (12, 14), having the steps: using a gas or gas constituent contained in the test object as test gas for the leak-tightness test, introducing the test object into the foil chamber, evacuating the foil chamber to a pressure lower than the test gas pressure within the test object and than atmospheric pressure, introducing a carrier gas into the foil chamber into the region outside the test object, and measuring the test gas concentration of the gas mixture that forms in the foil chamber in the region outside the test object.

摘要： Current can/end growth/buckle tester use inside the dome area of the can for location of the can during test, therefore cans with different height have the same vertical position during the test and do not depend from height of the can. Using flanged long bushing for locating the can with different height and holding expandable plug and distribution parts for air pressure permitted reduce outside dimensions of the tester and reduce weight. Use the position of the testing can on top of expandable rubber bushing by inside the dome area of the can, permitted using almost the same volume of the growth/buckle air for any can, therefore reduce dispersion of measurement values. Area for growth/buckle tests is sealed by expandable rubber bushing with the special internal shape and durometer, which has ability to sealed by inflation any diameter of the testing can and holding growth/buckle pressure during the test. The body of sectional clamps made as I-beam with placing turning cams inside sectional clamps and top holding plates on top of body reduce size and increase rigidity of the tester. Turning pins connect inside turning cams and top holding plates. This connection permit the wall of testing can control rotation both parts. Sectional clamps with turning cams and middle central part hold the testing can in vertical and horizontal positions permitted create uniform holding and clamping force during the tests. Turning cams with rubber plates and middle rubber plate installed on the middle of the sectional clamps permit contact the testing can around and relieve thin-walled can partially from inflation pressure of expandable rubber bushing. Angle of rotation turning cams depend and control by outside diameter of testing can. Extension springs control initial opening position of turning cams. Using Belleville spring and sectional clamps with top holding plates with chamfers for holding testing cans any diameter and height during the test, created stable vertical position of the testing can during growth/buckle tests. Cuts around Bellville spring make path for delivering testing air pressure for the growth/buckle tests. Edges of top holding plates hold testing can around the outside area of the testing can by their chamfers and create necessary space around the stand for growth/buckle tests. sectional clamps pressure hold the can against of the top holding plates and work at the same direction as Belleville spring making fixed vertical position of the testing can that increase tolerance of the tests. Pressure for inflation is coming directly to expandable rubber bushing, movement sectional clamps and growth/buckle tests deliver from the same manifold.

摘要： A method for testing the sealing tightness of a specimen, containing a gas, in a film chamber made from flexible material. The film chamber is evacuated by a vacuum pump and the gas flow flowing out of the film chamber and generated by the vacuum pump is measured during the evacuation and is examined with respect to a possible leak of the specimen.

摘要： The invention relates to a method for determining the rate of leakage on a non-rigid specimen, wherein the specimen is introduced to a film chamber which can be evacuated, having at least one wall region made of a flexible material and the pressure in the film chamber is reduced outside of the specimen. The pressure gradient within the film chamber outside of the specimen is measured. In order to increase the accuracy of the leak detection, an outer over-pressure is exerted on the flexible wall region during pressure measurement which exceeds the pressure in the film chamber and outside of the specimen and the pressure inside the specimen.

摘要： The invention relates to a method and an arrangement for detecting a leak in a sealed package containing a product in the form of a foodstuff or a pharmaceutical. The leak detecting arrangement comprises a testing station, in which a package is placed by the transporting means and a pressure applying means arranged to apply a predetermined amount of pressure on the package located in the testing station. The arrangement further comprises a continuously operated suction means arranged to draw ambient air past a seal on the packet to be tested and a gas sensor located in the flow of ambient air drawn off by the suction means and arranged to transmit a signal dependent on the test gas concentration detected in the ambient air.
