INTRODUCTION:
PN-BSM600 Bursting Strength Tester is a new type testing apparatus to test the bursting strength of corrugated boards, which is designed to be in accordance with related national 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 abundant 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.
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.
APPLICATIONS:
Corrugated cardboard, Corrugated Package.
