Burst strength

The burst strength , formerly also burst resistance , is a measure of the resistance of flat materials (paper, cardboard, foils, textiles) to pressure applied perpendicular to the surface. It is given in kilopascals .

To determine the bursting strength, a sample of the material is clamped in a ring-shaped holder and loaded evenly from above until it bursts. The corresponding standards are: for paper DIN EN ISO 2758; for cardboard DIN EN ISO 2759.

The ratio of bursting strength to weight per unit area gives the bursting index for papers .
