Textile Diaphram Bursting Testeralso as a kind of textile testing equipmenta multidirectional force generated by hydrostatic pressure is applied on fabric to check the strength of that fabric this phenomenon is called bursting strength testingAutomatic Hydraulic Diaphram Bursting Tester is specially designed to perform the bursting strength testing of kitted fabrics with pneumatic controlIt can also be used for leather paper card Boards etc
Smith Barney Inc are now able to offer a technically advanced machine that is easy to use and inexpensive to own

The Textile Burst Tester is designed for measuring the bursting strength of fabric materials subjected to an increasing hydrostatic pressure This pressure is applied to a circular region of the specimen via an elastic diaphragm The specimen is firmly held round the edge of this circular region by a pneumatic clamping device When the pressure is applied the specimen deforms together with the diaphragm The bursting strength corresponds to the maximum pressure supported by the specimen before failure Identical in the principle to the multidirectional tensile test Ball Burst Method for Fabrics this textile testing equipment is independent from the cutting direction of the sample machine or cross since the failure naturally occurs in the least resistance direction
Procedure
The fabric sample is clamped over the rubber diaphragm
The pressure in the fluid increases at such a rate that the specimen bursts within 20 3 sec P1
The height extension of the diaphragm is noted
Another test is carried out without a specimen
The pressure to do this is noted and then deducted from the earlier reading
P1 P2 is the actual bursting strength of the specimen
