The test principle of the hydraulic method is to clamp a certain area of the sample on an extendable diaphragm, and apply liquid pressure under the diaphragm. Then increase the volume of the liquid at a constant speed to expand the diaphragm and the sample until the sample ruptures, and the bursting strength and bursting expansion are measured. Commonly used hydraulic bursting strength tester is GESTER Bursting Strength Tester GT-C12A, Standards: ISO 13938.1, FZ/T 60019, FZ/T 01030, ASTM D3786, BS 4768, WOOLMARK TM 29, WSP 30.1, JIS L 1018.6. 17.
The test principle of the Pneumatic method is: clamp the sample on an extensible diaphragm, and apply gas pressure under the diaphragm. Then, increase the gas volume at a constant speed to expand the diaphragm and the sample until the sample ruptures, and the bursting strength and bursting expansion are measured. Commonly used pneumatic fabric bursting strength tester is GESTER Pneumatic Bursting Strength Tester GT-C12B, standards: FZ/T60019, ISO2960, ASTM D3786, M&S P27, JIS L-1096, ISO 13938-2.
