Air Permeability Test Procedure For Fabric

Fabric air permeability is a nature of air passing through fabric normally under the situation that two sides of fabric exist pressure difference that is to say it is speed that airflow vertically goes through fabric in a prescribed test area pressure drop and time whose unit is mm s or m s.

Air permeability test procedure for fabric.

Now tighten the specimen clamp securely. 1 first of all open the specimen clamp j. Fabric air permeability test. Read and record the individual test results in si units or in.

The volume of air passed per second through per unit area of the fabric is called air permeability of fabric. How the test works. The whole testing procedure gets completed in below steps. When you do air permeability testing for fabric there is different air permeability test method.

Air permeability tester of textile fabrics complies with astm d737 iso 9237 7231 bs 5636 etc. Air tightness also known as air leakage air infiltration or air permeability testing is a quick non invasive procedure put in place to measure the total air lost through leaks in the building fabric. A circle of fabric is clamped into the tester and through the use of a vaccum the air pressire is made. Place the specimen on the specimen fixing plate i.

It is used to test the resistance of the flow of air through fabrics. Air permeability tester price is competitive. Air permeability testing apparatus circular test head with a test area of 5 93 square inches 15 07 cm. Air permeability can be measured by using distinct test protocols for example astm d 737 and iso 9237.

To minimize air edge leakage.
