 The Maximum uniformly distributed pressure, applied at right angles to is surface, that a test
piece will stand under the conditions of the this test (SCAN P 24/25)
A test piece, placed over a circular elastic diaphragm, is redigly clamped at the periphery but free to bulge with the diaphragm. Hydraulic fuild is pumped at the constant rate, bulging the diaphragm until the test piece is the maximum value of the applied hydraulic pressure. For determining the bursting strength of paper and paperboard. Designed with pneumatic clamping of samples to avoid samples slippage under adjustable clamping force
A test piece is clamped between two concentric plates, each having circular opening in the center. Pressure is applied to the underside of a test piece by a rubber diaphragm, which is expanded by hydrostatic.The bursting strength is the maximum pressure required to burst a test piece and can be measured either by Bourdon Pressure Gauge or by Pressure Transducer in a Digital Readout.
