Bursting Strength is a superlative method which is performed on fabrics to measures the strength of the materials. Fabrics are usually stressed in all directions during service hence it is necessary to apply realistic stress on the materials to ascertain the strength of the fabrics in uneven conditions. Fabrics are usually failed due to bursting during the service or transportation.

When fabric fails due to continuous bursting strength, the material gets burst from the place where there are lowest breaking extensions. This happens when the stress is applied to the fabrics in all the directions, the material with low strength get burst first.


Diaphragm of Bursting Strength Tester

One of the highly standardized regularity describes a test in which the fabric is tested by clamping it over a rubber diaphragm by means of an angular clamping mechanism and increasing rate of pressure is applied through a purified lab grade liquid glycerin from below the diaphragm until the sample burst or ruptured. After the test is completed, the readings are recorded from the display. This explains the maximum pressure that a sample can bear to its maximum before it burst.

Presto Stantest offers a wide assortment of Bursting Strength Testers with customized specifications to fulfill the testing requirements that arises in different production verticals. The result that displayed on the device on completion of the test is considered as Bursting Strength of material. In addition to this, the next stage is to calculate the Burst Factor and Burst Index of the material using formulas:

Burst Index = Bursting Strength (KPa) x 0.10197 / Grammage (g/m2)

Bursting Factor = Bursting Strength (Kg/cm2) x 1000 / Grammage(g/m2)

Where, Grammage is the base weight.
1 KPa = 101.97162 Kgf/m2
