1. INTRODUCTION
Laboratory Mullen Burst Tester for bursting strength testing is a new type testing instrument to test the bursting strength of corrugated boards, which is designed to be in accordance with related ISO standards and on the principle of modern mechanical design concept and design criterion of human-machine engineering.
PN-BSM600 Bursting Strength Tester belongs to electromechanical product which is with novel design, convenience for use, excellent performance and elegant appearance.
PN-BSM600 Bursting Strength Tester has multi functions, such as, parameter testing, parametric transformation, parameter adjusting, parameter memory and parameter print. All are in accordance with related national standards. PN-BSM600 Bursting Strength Tester has data processing function which can directly output result of data statistics with convenient operation, easy regulation and stable performance.
2. PRINCIPE:
A test piece placed over a circular elastic diaphragm, it is rigidly clamped at the periphery but free to bulge with the diaphragm. Hydraulic fluid is pumped at a constant rate, and bulged the diaphragm until the test piece ruptures. The bursting strength of the test piece is the maximum value of the applied hydraulic pressure.
