 Test Principle

1) By evacuating the vacuum chamber, a pressure difference is created between the inside and outside of the sample immersed in water. The escape of gas from the sample is observed to determine the sample's sealing performance.

2) By evacuating the vacuum chamber, a pressure difference is created between the inside and outside of the sample. The expansion of the sample and its shape recovery after the vacuum is released are observed to determine the sample's sealing performance.
