초록

A method and apparatus are provided which are especially useful for leak testing seams such as an end closure or joint in an article. The test does not require an enclosed pressurized volume within the article or joint section to be leak checked. A flexible impervious membrane is disposed over an area of the seamed surfaces to be leak checked and sealed around the outer edges. A preselected vacuum is applied through an opening in the membrane to evacuate the area between the membrane and the surface being leak checked to essentially collapse the membrane...

청구항

A method for leak testing a seam in an article, comprising the steps of: covering said seam and the surfaces adjacent thereto with an impervious, flexible membrane readily conformable to said surfaces adjacent said seam; sealing the outer edges of said membrane to said surfaces; evacuating the volume between said membrane and said surfaces to collapse said membrane into a conforming contact with said surfaces and to concentrate at a small space between said surface and said membrane at said seam a pressure differential only across said seam; and checking...
