Textile burst strength test
The bursting strength of the fabric refers to the phenomenon that when the fabric is partially subjected to an external force perpendicular to its plane, it expands and ruptures, which is called the bursting strength of the fabric. Commonly used bursting strength test methods are: hydraulic method, Pneumatic method, and steel ball method.
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.
Steel ball method
The testing principle of the steel ball method is: The sample of a certain area is clamped in the ring sample fixed on the base, the round spherical push rod at a constant moving speed vertically against the sample, so that the sample deformation until the rupture, measured breaking strength. GESTER Ball Burst Strength Tester GT-C02-2, standard:
