Corrugated Board Bursting Strength Tester Principle:
A test piece placed over a circular elastic diaphragm, it is rigidly clamped at the periphery but free to bulge with the diaphragm. Hydraulic fluid is pumped at a constant rate, and bulged the diaphragm until the test piece ruptures. The bursting strength of the test piece is the maximum value of the applied hydraulic pressure.
