Test Principle
Method A
Providing a constant air flux going through the specimen vertically, the air permeability could be obtained by measuring the pressure difference.
Method B
Providing the constant pressure difference between two sides of the specimen, the air permeability could be obtained by measuring the air flux through specific area in the certain time.
