Fabric Ball-bursting Strength Tester, used for testing the ball-bursting strength and expansion rate of high elongation strength material i.e. cotton fabrics, elastic fabrics, sock and glove products.

In this test a 25mm diameter steel ball is pushed through the stretched fabric and the force required to do so is recorded. The advantage of the test is that it can be carried out on a standard universal strength tester with a suitable attachment. There is also no limit to the amount a sample can be extended as there is with the diaphragm test.
