The Bursting Strength Tester is designed to find bursting strength of geotextile/fabric/leather/paper/paper board. A test specimen is held between two annular clamps under sufficient pressure to minimize slippage. The upper clamping surface which is in contact with the test specimens has a continuous spiral grooves. A circular diaphragm of rubber is clamped between the lower clamping plate & pressure cylinder so that before the diaphragm is stretched by pressure underneath it the center of its upper surface is below the plane of the clamping surface. The equipment is fitted with a motor driven cam mechanism, which increases fluid displacement on the lower side of the diaphragm at a specified rate. The equipment is fitted with an arrangement, which automatically brings down the pressure and stops the motor on completion of the test cycle. A maximum reading type pressure gauge gives the bursting pressure. The equipment is raggedly designed to give a long & trouble free life.
