摘要： A method for leak testing includes a leak testing step and a reference leak step. In the leak testing step, a hollow work 20 as a test object is encapsulated in a work capsule 11. A test pressure is supplied to the work capsule 11 through a path 2a connected to the work capsule. A variation of pressure inside the work capsule 11 is detected in a condition in which the path 2a is shut-off, and a judgment is made whether a leakage through the work is generated based on the detected output. In the reference leak step, a reference leak device 30 having a known pinhole 31a is mounted on a work 20′ for reference leakage that is same as the work 20 as the test object. The work 20′ for reference leakage is encapsulated in the work capsule 11. The test pressure is supplied to the work capsule 11 via the path 2a, and a reference leakage is generated in the work 20′ for reference leakage via the reference leak device 30 in a condition in which the path 2a is shut-off. A variation of pressure inside the work capsule 11 accompanying the reference leakage is detected.

摘要： The growth/buckle tester relates to a device for testing strength of metal cans. Using the position of the can on top of Belleville spring and expandable rubber bushing, holding by sectional clamps with turning cams and middle central part from outside, permitted create uniform holding and clamping force in horizontal direction. Using chamfers on holding plates and turning cams for holding the testing can vertically create necessary space around the stand for growth/buckle tests. The chamber created inside the can with almost the same volume of volume of air for the test reducing dispersion of measurement values. Cuts around of Bellville spring make path for delivering testing air pressure for the growth/buckle tests. Angle of rotation turning cams depend and control by outside diameter of testing can.

摘要： A leak rate testing system for pressured containers such as inhalers includes a test chamber holding the pressurized containers and accumulating compounds leaking from the containers. A sample cell receives the compounds from the chamber and a spectroscopy system obtains spectral responses of compounds in the sample cell so that a controller can determine leak rates over time.

摘要： A method and apparatus for leak testing of liquid and non-liquid filled rigid and semi-rigid nonporous containers wherein a container is enclosed in a conforming test chamber and subjected to vacuum while the pressure within the chamber is monitored by an absolute pressure transducer, alone or in combination with a second differential transducer, to determine if leaks are present in the container and wherein the test apparatus or system remains under low pressure or vacuum conditions while leak tests are not actively in progress such that the system is maintained at an at-rest low vacuum condition to minimize pressure sensor drift and to eliminate build-up of vapors or gases within the apparatus or test system between tests that may hinder the speed and sensitivity of the leak tests.

摘要： A dustproof and waterproof performance detection device for a user to observe a dustproof and waterproof performance detection process of an object by naked eyes is described. The detection device includes a box with at least one transparent side, a carrier, and a gauge. The carrier is movable in the box in a depth direction of the box. The box carries water for a tester to perform the dustproof and waterproof performance detection, such that the tester uses the carrier to carry the object, so as to move the object to a detection position and compare with scales of the gauge. Therefore, the tester is able to participate in the whole detection process.

摘要： A method of detecting oxygen leakage. Firstly, a detection wafer with a first color positioned on the substrate is provided. Then, the detection wafer is loaded into a reaction tube from a loading chamber, and subsequently, the detection wafer is unloaded from the reaction tube. Finally, the detection wafer is observed to obtain a second color, wherein if oxygen leaks into the loading chamber, the second color is different from the first color.

摘要： For leak testing closed containers (9) which are filled with a filling product containing at least one liquid component the container is introduced in a test cavity (1) which is evacuated at least down to vapor pressure of that liquid component. The pressure in the surrounding of the container (9) and thus within test cavity (1) is monitored. Monitoring is performed by a vacuum pressure sensor (7), whereas lowering pressure surrounding the container (9) is performed by a vacuum pump (5). Leakage is detected by monitoring a pressure change in the surrounding of the container which is due to evaporation of liquid emerging from a leak and being evaporated in the low pressure surrounding.
