Hydraulic Burst Test
The evaluation of bursting strength in dry and wet state test (ISO 13938) uses a hydraulic method for determining bursting strength and distension in textiles. The test is performed on materials such as gowns, drapes, and clean air suits, and is part of the test suite required by the EN 13795 guidance. This guidance determines performance requirements and performance levels for gowns, drapes, and clean air suits when used as medical devices. Nelson Laboratories can perform all EN 13795 testing.

Study OutlineFor burst testing, specimens nee to be large enough to allow for at least 5 tests to be performed on each specimen. Specimens are conditioned for wet and/or dry testing, and clamped in the burst tester. The pressure is increased at a constant rate until the sample bursts. The pressure at burst, time to burst, and height at burst are recorded.
