US Patent 7274447 Material porosity pressure impulse testing system

A system and method for determining porosity of a material enables rapid testing of materials by detecting test particle penetration. The material is held by a test chamber wherein a test particle solution covers a surface of the material. The test chamber is pressurized to a predetermined pressure, predetermined temperature and for a predetermined time. After the pressure is released the test particle penetration/diffusion into the material is then detected through differential fluorescence of the test particle.
