Bursting strength of linerboard
1.1 This method describes a procedure for measuring the bursting strength of linerboard using a disk shaped diaphragm. Basis weights for this method should be 20#/MSF and higher. The minimum burst should be 350 kPa (51 psi). Paperboard can also be tested using this method
1.1.1 A specimen of linerboard is clamped between two platens with circular openings in their centers. An expansible diaphragm 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.
1.2 For the bursting strength of paper with basis weights below the 20#/MSF use TAPPI T 403 "Bursting Strength of Paper,." For corrugated combined board and solid fiberboard, see TAPPI T 810 "Bursting Strength of Corrugated and Solid Fiberboard."
