|Opening In Lower Clamp||38.1 mm diameter|
|Opening In Upper Clamp||35.5 mm diameter|
|Rate Of Fluid Displacement||95 to 170 cc/minute|
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 producing rapture of the material when pressure is applied at a controlled increasing rate through a rubber diaphragm. It 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.
