Mullen Burst Testing

The Mullen burst test was initially conceived as a method of determining the ability of fabric to resist penetration by human elbows. A 1 inch diameter of material was pressurized from one side by means of a hydraulically driven membrane. The pressure necessary to force the membrane through the test material was referred to as its “burst strength”.

The testing and procedure were adopted by the paper and corrugated box manufacturing business and became a widely used test specification that is still common today. This procedure is closely related to a number of tensile test procedures.
