Explain a method for measuring the bursting strength of board submitted to increasing hydraulic pressure.

This International Standard specifies a method for measuring the bursting strength of board submitted to increasing hydraulic pressure. It is applicable to all types of board (including corrugated and solid fibreboard) having bursting strengths within the range 350kPa to 5500kPa. It is also applicable to papers or boards having bursting strengths as low as 250kPa if the paper or board is to be used to prepare a material of higher bursting strength, such as corrugated board. In such cases, the measurements will not necessarily have the accuracy or precision stated for this method and it is necessary to include a note in the test report stating that the test gave results that were below the minimum value required by the method.

In the absence of any commercial agreement as to which method should be used for materials with bursting strengths between 350kPa and 1400kPa, all materials with bursting strengths below 600kPa, except components of solid and corrugated fibreboard, should be tested by ISO2758 and the remainder by this International Standard.
