Full Description

This method describes a procedure for measuring the bursting strength of paperboard, includinglinerboard having a bursting strength of approximately 350 kPa (or 250 kPa by doubling the test specimens) or greater, employing a disk-shaped, molded diaphragm type instrument.

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

For the bursting strength of paper, see TAPPI T 403 Bursting Strength of Paper, for that of corrugated and solid fiberboard, see TAPPI T 810 Bursting Strength of Corrugated and Solid Fiberboard.
