ISO 2759 board burst strength tester is for the bursting strength of corrugated boards, which is designed in accordance with ISO2759 'Board-Determination of bursting strength'.
Board burst strength tester principle:
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 diaphram until the test piece rutures. The bursting strength of the test piece is the maxium value of the applied hydraulic pressure.
