Standards of Sealing Tester
GB/T-15171-1994, ASTM-D3078-94
Professional Sealing Tester Principle
By evacuating the vacuum chamber, the sample immersed in water generates a pressure difference between inside and outside, and determine the sealing performance of the sample by observing the gas outgoing and how the sample expands and restore to its original shape after vacuum release.
