AB - Temperature plays an important role in the gas permeability test. A small  temperature variation still exists in the experimental process since the  temperature control device cannot strictly maintain a constant temperature.  This can further affect the accuracy of the gas permeability. To solve this  problem, a simple method based on the ideal gas equation of state is  introduced to calibrate the gas pressure variation because of the  temperature effect. We verified the calibration results through sever­al  examples, and the results proved the feasibility and effectiveness of the  method. In particular, this method is particularly effective for low  permeability materials in long-term gas permeation tests.
