The specimen is put into the test chamber, clamped with suitable flanges with central screw and round gaskets. A known water pressure is applied on the specimens surface for a known time, as requested by Standard using a suitable air compressor having at least 5 bar pressure. Concrete Water Impermeability Apparatus Six Place apparatus is used to determine the depth of penetration of the water into the concrete (impermeability) under known time and pressure. The unit accepts concrete cubic, cylindrical or prismatic specimens having max. dimensions of 200x200x200 mm. A manometer checks constantly the applied water pressure. The water penetrated is measured by breaking the specimen, or by reading the water permeated through the graduated burette. The apparatus is supplied complete with graduated burettes fixed on the front panel.
