Burst Testers are used as a multi-directional tensile test to identify failure in the direction of least resistance for evaluating physical burst strength and fiber bond in textile and nonwoven materials. Models are available to test a variety of materials. These models can also be fitted with a device to measure the deflection of the sample prior to burst.

The Burst Tester is designed to meet international standards for tests on paper, foils, paper boards, corrugated board, textiles etc.

Textile and Non-Wovens Testing
Nonwoven and Textiles
The Burst Tester is designed for measuring the bursting strength of fabric materials subjected to an increasing hydrostatic pressure. This pressure is applied to a circular region of the specimen via an elastic diaphragm. The specimen is firmly held round the edge of this circular region by a pneumatic clamping device. When the pressure is applied, the specimen deforms together with the diaphragm. The bursting strength corresponds to the maximum pressure supported by the specimen before failure. Identical, in the principle to the multi-directional tensile test, Ball Burst Method for Fabrics, this measurement is independent from the cutting direction of the sample (machine or cross) since the failure naturally occurs in the least resistance direction.
