Rapid air permeability test using vacuum chamber was examined in testing conditions and the validity as the evaluation method of scaling resistance. The testing condition of rapid air permeability test was decided based on the outcome of an experiment. For the rapid air permeability test, the sealing width of 60mm was secured around the chamber and a distance of 150 mm was secured from the specimen edge to the center of the chamber. These test conditions reduced the coefficient of variation to 15% in the air permeability test. Rapid air permeability factor was found to be in good compatibility with Torrent air permeability factor. Also, this factor was found to be compatible with the amount of scaling by the ASTM C672 method. As a result, the usefulness of the rapid air permeability test method was proven.
