The pre-conditioned specimen is mounted in the gas diffusion cell to form a sealed barrier between two chambers. The lower-pressure chamber is first evacuated, followed by the evacuation of the entire cell. Gas is then introduced into the evacuated higher-pressure chamber, creating a constant pressure difference between the two chambers. The gas permeates through the specimen from the higher-pressure side to the lower-pressure side. By monitoring the pressure changes in the lower chamber, the gas permeability and other barrier properties of the specimen can be determined.
