Air Permeability Apparatus to determine air permeability of decorating materials used in cars, e.g. polyurethane, expanded plastics, PVC, leather, textiles, nonwovens and other materials.
Air Permeability Tester of textile fabrics complies with ASTM D737, ISO 9237/7231, BS 5636, etc. It is used to test the resistance of the flow of air through fabrics. There is different air permeability test method to do air permeability testing for textiles, we can offer all the test methods and competitive price.
Testing Standards:
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
Applications:
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.

ASTM D737 Frazier air permeability test method：
1.Air permeability definition
What is air permeability? The air permeability is the volume of air passing a fabric under pressure. There are two types of air permeability tester for textiles, Frazier air permeability tester and Shirley air permeability tester. In ASTM D737 test method, we take Frazier air permeability tester as example.
2.Test Objectives:
To determine the air permeability of textile fabrics by calculating the air permeability value.
3.Test Materials:
Woven, knitted and non woven textile mat
