Bursting Strength Tester

Bursting strength of any material such as fabric, leather, paper etc. is its strength under action of a multi-directional force and is defined as the hydrostatic pressure required to produce rapture of the material when pressure is applied on one of its surfaces at a controlled increasing rate through a rubber diaphragm.

"Innolab" Bursting Strength Tester is designed to find bursting strength of fabric / leather / paper / paperboard. 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 specimen has a continuous spiral groove and the lower clamping surface has a number of concentric grooves. A circular diaphragm of pure gum rubber is clamped between the lower clamping plate and the 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 increased fluid displacement on the lower side of the diaphragm at a specified rate. The equipment is also provided 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 Tester is finished in off white stoving enamel paint and bright chrome / zinc plating to give it a corrosion resistant finish.
For conducting tests on material where one pressure gauge does not cover the full range of loads encounted with the desired accuracy in measurement, a special model fitted with two pressure gauges with isolating valves is also available.
