During the test, the sample is pressurised with uniform pressure until the seal or weakest point of the box or paper burst. This method is designed to measure the maximum bursting strength of paper and paper products having a bursting strength of 50 kPa up to 1200 kPa (7 psi up to 157 psi) and in the form of flat sheets of up to 0.6 mm (0.025 in.)

Usually, bursting strength depends on the type, proportion, and amount of fibers present in the sheet, their method of preparation, their degree of beating and refining, upon sheet formation, and the use of additives. burst strength: Pressure at which a film or sheet (of paper or plastic, for example) will burst. Bursting strength of paper. Bursting Strength of the materials is a major property that defines the strength and quality of the packaging products. The bursting strength of the paper changes with the change in the weight of the paper. This property of the packaging helps to measure the strength and quality of the materials and helps to determine the suitability of the material for different applications. The paper burst test is different from cartons burst test because the high-capacity of bursting strength testers has large rubber diaphragm and is used to measure the bursting of cardboard, fiberboards, corrugated boxes, heavy paper boards, etc. ISO 2758:2014 specifies a method for measuring the bursting strength of paper submitted to increasing hydraulic pressure. Significance and Use 4.1 Bursting strength is widely used as a measure of the resistance to rupture in many kinds of paper.

Paper’s bursting strength is a vital strength property that is affected by many other properties of the sample, principally tensile strength and stretch. To test the bursting strength of the multi-layered papers and paperboards, high-quality of bursting strength testers with the superior quality of diaphragm is used. Determined by procedures such as Mullen burst test, it is expressed commonly in pounds per square inch (psi). Used as a measure of resistance to rupture, burst strength depends largely on the tensile strength and extensibility of the material. thick. Terminology 3.1 Definitions: Definitions shall be in accordance with Terminology D 1968 and the Dictionary of Paper.4 4. ISO 2758 Paper—Determination of bursting strength 3 2.3 TAPPI Standard: TAPPI T 403 Bursting strength of paper4 3. bursting strength of paper, in kilopascals, divided by the grammage of the paper determined in accordance with ISO 536 Only informative sections of standards are publicly available. It is applicable to paper having bursting strengths within the range 70 kPa to 1 400 kPa. The BS of paper can be measured by applying the maximum amount of hydrostatic pressure on the material which is required to burst the paper.

The bursting strength of a paper material explains the amount of pressure that a material can tolerate before it ruptures.
