BS EN ISO 22282-2 an international standard that specifies requirements for determining the local water permeability of soils and rocks in an open borehole

  1. Setup: Assemble the rigid-wall permeameter. Ensure it is clean and free of leaks.
  2. Sample Mounting: Place the soil sample (either undisturbed from a core barrel or remolded) into the permeameter cylinder.
  3. Saturation: De-air water and saturate the sample from the bottom up to remove trapped air.
  4. Test Selection:

    Current Status: The 2012 version remains current and was last reviewed and confirmed by the International Organization for Standardization (ISO) in 2023. Primary Test Methods bs en iso 22282-2 pdf

    2. The Falling Head Method

    • Best for: Silts, sandy silts, low-permeability soils.
    • Procedure: A standpipe is filled with water, and the time taken for the water level to fall from a starting head to a final head is recorded.
    • Typical k value range: 10⁻⁷ to 10⁻⁵ m/s

    A very specific request!

    Test Environment: Applicable for stable and non-stable soil/rock, as well as unsaturated conditions. BS EN ISO 22282-2 an international standard that
