The most accurate permeability measurement technique involves laboratory constant head testing per ASTM D2434 standards using specialty columnar chambers allowing water flows through compacted or undisturbed soil samples under controlled hydraulic gradients.. Here is a comparison of the constant head and . The common water vapour permeability tester. Four methods to test the water vapour permeability. Method 1: method of moisture absorption (desiccant) First, expose the desiccant (anhydrous calcium chloride) particles (0.63~2.5 mm) to an oven at 160℃ for 3 hours to make them completely dry. The Water Permeability Test is performed following standards such as BS EN 12390-8 and DIN 1048 Part 5. These involve measuring the depth of water penetration into concrete samples under specific hydrostatic pressure for a set period. The water permeability testing process includes: Casting and curing concrete samples for 28 days
