Hydraulic Bursting Strength Tester
The Hydraulic Bursting Strength Tester measures the bursting strength and bursting distension of woven, knitted, and nonwoven fabrics, paper, paperboard, and other suitable sheet materials. It applies hydraulic pressure beneath an elastic rubber diaphragm until the specimen bursts, recording the pressure and deformation at the point of failure.
To determine the bursting strength and distension at burst of woven, knitted and non woven fabrics, papers and boards by the application of hydraulic loading under a rubber diaphragm. The intelligent control algorithm gives accurate control of the burst time. Manual or automatic mode. Windows based software could analyze the test results and print, easy to operate. Different test areas can be accommodated allowing testing to corresponding standards.
