Auto Pneumatic Bursting Strength Tester

Determination pressure for a variety of fabrics, including knits, woven fabric, non-woven fabric, laminated fabric and other craft-made variety of fabrics, in standard conditions or under wet bursting strength and bursting dilation.

Standards ISO13938-2, ASTM D3786, IWS Tm29

Test principle:

Through the circular clamping the sample holder can be extended in the diaphragm, the gas pressure applied below the diaphragm, the diaphragm and the sample expansion. Rate of increase has been constant pressure until the sample burst, measured burst strength and burst dilation.

Instrument features:
1,Computer control, automatic burst test, automatic calibration, automatic data processing, experimental form of a report output.
2,Air power, high cleanliness.
