The ToronAPT™ 5636 securely clamps the specimen over the selected test head, applies a controlled differential pressure, and directs air through the material. The standard Gurley test pressure is 1.22 kPa, while the test-head area determines the exposed specimen area during measurement.\u003c\/p\u003e\n\u003cp\u003eAir resistance is expressed in Gurley seconds, representing the time required for a specified volume of air, typically 100 cm³, to pass through the specimen. Materials with lower air permeability generally require more time and produce higher Gurley values. Air permeance, expressed in µm\/Pa·s, indicates how readily air passes through a material under a given pressure difference and test area. The instrument calculates the relevant measurement from the recorded pressure and airflow data.\u003c\/p\u003e\n\u003cp\u003eHigh-accuracy pressure and flow sensors continuously monitor test conditions, while the automatic pressure-control system maintains the required differential pressure throughout the measurement. This helps minimize variations caused by changing test conditions and supports repeatable results.\u003c\/p\u003e\n\u003cp\u003eInterchangeable test heads and adjustable pressure settings allow the ToronAPT™ 5636 air permeability tester to accommodate materials with different permeability levels, from relatively dense battery separator membranes to highly air-permeable nonwoven fabrics, using a single testing platform.\u003c\/p\u003e\n\u003ch2\u003eAir Permeability Tester - ToronAPT™ 5636 Technical Specifications\u003c\/h2\u003e\n\u003ctable class=\"table\" border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eTest Range (Gurley)\u003c\/td\u003e\n\u003ctd\u003e30 to 60,000 Gurley seconds (standard);
