Abstract

A method and apparatus of testing the integrity of a hollow article 12 having an opening 22 therein, by a leak detection procedure. The article 12 is placed in a test chamber 1 with the opening exposed and the chamber sealed. The chamber 1 is then evacuated (6). A closure device 13, 21 mounted on the wall 4 of the test chamber is then operated from outside the chamber to close the opening 22 in a vacuum-tight manner. Evacuation is then continued of either the interior of the article or the space within the chamber surrounding the article to produce a pressure differential across the wall of the article. A test gas 19 is admitted to the region of higher pressure and a test gas detector 8 is connected to the region of lower pressure. Connections to the interior of the article may be made through the closure device 13. If the article is substantially cylindrical i.e. has a second opening opposite the first opening 22, a seal 43 on the floor of the test chamber can be used to seal the second opening. <IMAGE>
