Firstly submerge the specimen in the water within the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The leakage property could be obtained by observing the steady progression of bubbles from the specimen and how the specimen expands and restores to its original shape after vacuum release.
