Key Features of Bursting Strength Tester with Upper Clamping Surface

• Bursting Strength of any material such as fabric, leather, paper, etc.
• Is its strength under multidirectional 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.
• The 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 minimise 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 & 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.
• The equipment is fitted with a motor driven cam mechanism which increases fluid displacement on the lower side of the diaphragm at a specified rate.
• The equipment is fitted 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 equipment is ruggedly designed to give a long & trouble free life.
• The components are either chrome plated or painted in hammertoe finish to give the tester an aesthetic appearance.
• For conducting tests on material where one pressure gauge does not cover the full range of loads encountered with the desired accuracy in measurement, a special model fitted with two pressure gauges with an isolating valve can be offered.
