The Penetration Test Cell, designed in accordance with ASTM F903 and ISO 13994 standards, securely holds the test specimen during exposure to a pressurized challenge fluid. The cell body accommodates approximately 60 ml of synthetic blood or bacteriophage test fluid. This test method is widely used to assess the liquid barrier performance of materials, seams, closures, and other planar assemblies used in protective clothing and safety apparel, ensuring reliable resistance to liquid penetration under controlled conditions.
