Burst Strength

Pressure at which the prothesis bursts.

Test Procedure

The sample is distended by filling the prosthesis directly with fluid at a measured rate of pressure change until bursting of the sample takes place.

Scope

Only possible for devices with low permeability which are able to hold pressure. Otherwise see the Balloon Method of determining burst strength
