Full Description

TAPPI T 807 om-16 describes a procedure for measuring the bursting strength of linerboard using a disk shaped diaphragm. Basis weights for this method should be 98 g/m2 (20#/MSF) and higher. The minimum burst should be 350 kPa (51 psi). This method may also be used to test paperboard.

A specimen is clamped between two platens with circular openings in their centers. An expansiblediaphragm is distended through the lower platen by means of hydraulic pressure until the specimen ruptures. The maximum hydraulic pressure when the specimen ruptures is recorded.

For the bursting strength of paper with basis weights below 98 g/m2, use TAPPI T 403 "Bursting Strengthof Paper." For corrugated combined board, see TAPPI T 810 "Bursting Strength of Corrugated Board."
