TQD-G1 Air Permeability Tester

This equipment is designed and manufactured according to  GB/T 10655-2003 which is equal to ISO4638-1984, and compatible with GB/T5453-1997, ISO9237-1995, ASTM D737-96, GB/T4689.22-1996, GB/T13764-92 and other related standards. We also refer to standards and criterions of many international famous automotive manufactures. This equipment is applicable for air permeability test and air resistance test for auto seat materials like PVC, foam, leather, textile, non-woven cloth, and so on. Users can control materials’ properties trough test, then to meet the actual requirements.

1. Principle
A. Adjust the system to Produce a constant air flux passes through the specimen vertically, then test the deferential pressure between the two sides of the specimen under this condition and calculate the ventilation resistance.
B. Adjust the system to produce a constant pressure, then test the air flux that passes through the given area vertically within definite time and calculate air permeation.
C. Other test function.
