The instrument is used to determine the bursting strength of textile fabrics. Bursting strength of a material is defined as the hydrostatic pressure required to produce rupture of a material when the pressure is applied at a controlled increasing rate through a rubber diaphragm. It is actually strength of a material under multi-directional force. The instrument is used for testing bursting strength of materials like leather, paper, etc.

Salient Features

• The specimen to be tested is held between two annular locks or clamps under optimum pressure to eliminate chances of slippage.
• There is a continuous spiral groove at the upper clamping surface. There are a number of concentric grooves on the lower clamping surface.
• There is a circular diaphragm made of gum rubber that is fixed between the lower clamping plate and a pressure cylinder.
• There is a motor driven cam mechanism in the machine which increases fluid displacement on the lower side of the diaphragm at a specific rate.
• Provided with a digital pressure gauge with peak memory that indicates the maximum pressure achieved before failure of the test specimen.

Applications

Some of the application area of the bursting strength tester are:

• Textile Industry
• Paper Industry
• Leather Industry
