Product Brief The N600P Paper & Paperboard Air Permeability Tester is custom-developed to align with standards like GB/T 458-2008 and ISO 5636. It adopts the differential pressure method as its core testing principle, and innovatively integrates three industry-common testing approaches (Gurley, Schopper, and Bendtsen) into a single device.   This tester is applicable to air permeability detection of various paper and paperboard materials, and can measure key indicators including: material air permeability, air resistance, gas transmission rate, and total gas transmission volume. Testing Principle Gurley Method   Under a constant differential pressure of 1.23 kPa, measure the time required for 100 mL of gas to pass through the sample. Schopper Method   Select a suitable test duration under a constant differential pressure (1.00 kPa±0.01 kPa or 2.50±0.01 kPa), and calculate the gas flow rate through the sample by measuring the gas 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 surface of the sample.

Product Brief The N600C Carbon Paper Air Permeability Rate Tester is designed and developed in accordance with GB/T 20042.7-2014. Adopting the differential pressure method as its testing principle, it is professionally used for measuring the air permeability rate of various types of carbon paper for proton exchange membrane fuel cells (PEMFC). Testing Principle Based on the differential pressure method, the sample is placed between two fixtures, forming a constant differential pressure on both sides of the sample. Driven by the differential pressure, gas flows from the high-pressure side through the sample to the low-pressure side. The air permeability rate of the carbon paper is calculated based on the transmission flow rate, sample thickness, test area, and test differential pressure.
