The burst test is frequently used as a general guide to the strength of paper, solid board and corrugated board. Bursting strength is usually quoted in kPa. We determine bursting strength using a digital hydraulic paper or digital hydraulic board burst tester.
Burst index (kPa.m2/g) = burst strength/basis weight
