This test method describes the measurement of the bursting strength of paper. This method applies to paper products having a bursting strength of 50 kPa up to 1200 kPa (7 psi up to 175 psi) and in the form of flat sheets with a maximum thickness of 0.6 mm (0.025 in.). Materials that can be tested using this method include newsprint, bag paper, fine paper, packaging paper, and printing papers. It is not intended for use in testing corrugated, fiberboard, linerboard, or hardboards that tend to cut the thin rubber diaphragm of the bursting tester. For testing paperboard and linerboard, see TAPPI T 807 “Bursting Strength of Paperboard and Linerboard”; for testing corrugated and solid fiberboard, see TAPPI T 810 “Bursting Strength of Corrugated and Solid Fiberboard.”
