  1. Mullen Burst Strength is the bursting strength of a coated fabric under a test method used to meet ASTM test standard D751. In the Mullen Burst Test, a circular material sample is clamped over a diaphragm and inflated with oil. Pressure is applied until the fabric bursts. The failure pressure (measured in pounds per square inch) is the bursting strength.
