Bursting Strength Tester

Listing ID #3668953

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.
