Application of Air Permeability Tester

Air permeability Tester is calculated by measuring the flow rate of air flow perpendicular to the given area of the sample within a certain time under the specified pressure difference condition. It conforms to various test standards of GB, ISO and ASTM, and can set pressure difference to meet different requirements.

Electronic measurement principle:  built-in high-precision electronic flowmeter, inlet pressure sensor. The pressure sensor is used to test the pressure difference on both sides of the sample, and the transmission data is calculated by the central processing unit.

 Conditioning: Specimen should be conditioning in the environment of 20±2℃, 65±2%RH.

Testing times: According to the related standards GB/5453 requires at least 10 times in different place in one sample. And DIN 53887 requires at least 5 times.

Specimen size :In general, sample needn’t be cut, it can be tested directly. If you need to cut, size of sample at least 25cm × 25cm (ASTM D737) or 20cm × 20cm (DIN53887).
