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