Product Brief
The N600P Paper & Paperboard Air Permeability Tester is designed and developed in accordance with standards such as GB/T 458-2008 and ISO 5636. Adopting the differential pressure method as its testing principle, it integrates three testing methods (Gurley method, Schopper method, and Bendtsen method) into one machine. It is suitable for testing the air permeability of various types of paper and paperboard, and can measure indicators including air permeability, air resistance, transmission rate, and transmission volume of materials.
Testing Principle
Gurley Method: Measure the time required for 100 mL of gas to pass through the sample under a constant differential pressure of 1.23 kPa.
Schopper Method: Under a constant differential pressure of 1.00 kPa±0.01 kPa or 2.50±0.01 kPa, select an appropriate test duration and determine the gas flow rate through the sample by measuring the volume.
Bendtsen Method: After clamping the sample for 5 seconds under a constant differential pressure of 1.47 kPa, test the gas flow rate through the test surface.
Executed Standards
