Burst Test

What is the goal of a burst test?

The aim of a burst test in the area of medical device testing is to determine the maximum pressure load at which a packaging (sterile barrier) fails under internal pressure. The pressure is gradually increased until the packaging bursts to evaluate the sealing force.

The test is designed to ensure that the packaging opens at the seal seam and that no material rupture occurs. The burst pressure can be used as a parameter for further tests, such as in-process control.

What happens during a burst test?

A burst pressure test is a test in which the internal pressure of a package is increased to determine at what pressure it bursts and whether the failure point is at the seal, or if the material breaks.

The ability of a package to withstand increased internal pressure can be investigated. With this strength test, the entire seal area can be evaluated, thus identifying the weakest area.

In which area are burst tests used?

The burst pressure test on packaging, in particular sterile barrier systems, is used as part of packaging validation in accordance with DIN EN ISO 11607-1 or as an in-process control in packaging production.
Standards: ASTM F1140/F1140M, DIN EN ISO 11607-1, DIN EN ISO 11607-2
