Test Principle

The pre-conditioned specimen is mounted in the test cell as to form a sealed barrier between two chambers. The lower-pressure chamber (lower chamber) is firstly evacuated, followed by the evacuation of the entire cell. A flow of gas is thereafter introduced into the evacuated higher-pressure chamber (upper chamber) and a constant pressure (adjustable) difference is generated between the two chambers. The gas permeates through the specimen from higher pressure side into the lower pressure side. The gas permeability of the specimen can be obtained by analyzing the pressure changes in the lower chamber.
