Bursting strength of any material such as fabric, leather, paper etc. is its strength under multi-directional force and is defined as the hydrostatic pressure required to produce rapture of the material when pressure is applied at a controlled increasing rate through a rubber diaphragm. The GLOBE 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 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 a pressure cylinder so that before the diaphragm is stretched by pressure underneath it the centre of its upper surface is below the plane of the clamping surface.
