BS 5636, JIS L1096-A, DIN 53887, ASTM D737, ASTM D3574, EN ISO 9237, GB/T 5453, EDANA 140.2, TAPPI T251, EDANA 140.1, ASTM D737, AFNOR G07-111, ISO 7231


The Air Permeability Tester accurately and swiftly determines the resistance of fabrics (woven, knitted and nonwoven textile) to the passage of air (air flow) under constant pre-set air pressure while firmly clamped in the test rig of selected test head/area. The air permeability of the fabric is calculated automatically within a short time.
