Bursting strength - Board burst and paper burst

At Pira, bursting strength is determined using a Messmer digital hydraulic paper or digital hydraulic board burst tester. 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.
