Using the ‘push to burst’ switch to apply the hydraulic pressure on the sample. The pressure is applied via a rubber diaphragm which inflates when hydraulic pressure is increased. The point at which sample burst, the machine notes down the pressure applied. Using this bursting strength, bursting factor and bursting index can be determined.A test piece, placed over a circular elastic diaphragm, is rigidly clamped at the periphery but free to bulge with the diaphragm. Hydraulic fluid is pumped at a constant rate, bulging the diaphragm until the test piece ruptures. The bursting strength of the test piece is the maximum value of the applied hydraulic pressure.
