Product Description
Paper Air Permeability Test Machine is used to determine the air permeability of paper
Test standard: ISO5636-2
Test principle
Using the differential pressure method, the pre-treated sample is placed between the upper and lower measuring faces to form a constant pressure difference on both sides of the sample. Under the action of the pressure difference, the gas flows from the high-pressure side through the sample to the low-pressure side, and the gas permeability of the sample is calculated according to the area, pressure difference and flow rate flowing through the sample.
