Principle and Standards


Firstly, the specimen must be submerged in the water within the vacuum chamber, and then the vacuum chamber should be evacuated to form differential pressure between the outside and inside of specimen. The leakage property could be acquired by observing the steady progression of bubbles from the specimen and how the specimen expands and returns back to its original shape after vacuum release.


This test instrument complies with the standards: GB/T 15171, ASTM D3078


The MFY-01 Leak Tester is applicable to the determination of leakage property of:
