Principle

A. Adjust the system to produce a constant air flux passes through the specimen vertically, then test the deferential pressure between the two sides of the specimen under this condition and calculate the ventilation resistance.

B. Adjust the system to produce a constant pressure, then test the air flux that passes through the given area vertically within definite time and calculate air permeation.
