Scope and Principle

To determine the strength of knitted fabrics, by means of distending the fabric to a point where it either ruptures or fully fills the dome.

Bursting Strength – Distending force which is applied at right angles to the plane of the fabric, under specified conditions, which will result in the rupture of a textile.

This test is used to determine the resistance of textile materials to bursting using

Test Procedure

Refer to BS EN ISO 13938-2: 1999 (using a diameter dome)
Hydraulic Diaphragm bursting tester –
Diaphragm Burst

The area of sample of fabric to test is clamped over an elastic diaphragm by means of a flat annular clamping ring, and an increasing fluid pressure is applied to the underside of the diaphragm until the specimen bursts.
Diaphragm Bursting
