Cell Instruments’ Bursting strength tester – Digital Pneumatic with Printer is designed to measure the bursting strength of the paper, cloth, corrugated fibre, etc. This high-end model is designed with pneumatic clamping to ensure that there is no slippage of the sample. The hydraulic pressure is applied to the sample via rubber diaphragm. The medium of pressure is glycerin. The pressure is applied on the test sample until it ruptures. The pressure required to burst the sample is considered as the bursting strength. It is represented in kg/cm². It is equipped with a small thermal printer alongside to immediately print the test results.
Bursting strength is an important factor to determine the quality of the raw material. Many industries cannot approve a bit of sample until testing it for its bursting strength.
Cell Instruments Bursting Strength Tester is manufactured under various Test Standards ASTM D3786-01, ASTM D 3786 – 80A, ISO 1060 PART-1 1987.
