This paper shows the result of the mechanical loading tests, the leakage tests and FEM simulation of a glovebox window specimen to secure safety of the glovebox containment. The leakage tests were conducted for test specimens that represent one full-scale glovebox resin window panel and panel to flame sealing. In leakage tests, pressure difference and temperature were observed after three deformation mode of frame and two deformation mode of window panel were applied to the test specimens. In numerical simulation, the large deformation FEM analysis was applied to evaluate sealing mechanism of glovebox window. As the results, the glovebox window constructed with the rubber seal and the resin panel shows no leakage lager than 0.1vol%/h with large static deformation. In numerical simulation, two small rips of the rubber seal plays important role on the containment of the glovebox.
