Battery Diaphragm Air Permeability Tester N600E

The Battery Diaphragm Air Permeability Tester N600E has been designed and developed in accordance with GB/T 36363-2018 and various other standards. Utilising the differential pressure method, this tester is specialised for assessing the air permeability of battery separators, breathable membranes, and relevant polymer materials.

Test Principle In an environment with specified test temperature, humidity, and normal pressure, the instrument applies a pressure of 1.21 kPa, measuring the time it takes for 100 mL of air to pass through the diaphragm with an area of 6.45 cm2.

Standard ISO 5636-5, TAPPI T460, GB/T 36363
