, where water is injected into or withdrawn from an isolated section of a borehole without the use of permanent seals or closed-loop pressure monitoring typical of Part 6. It applies to both saturated and unsaturated conditions , above and below the groundwater level. cdn.standards.iteh.ai Primary Test Methods bs en iso 22282-2 pdf
Engineers and geologists rely on these tests to predict how water moves through the ground. This information is critical for: The standard follows a structured format common to
This part specifically focuses on performed in boreholes or test pits, excluding laboratory tests on soil samples (which are covered in other standards like ISO 17892-11). This information is critical for: This part specifically
: Water is introduced or extracted to maintain a fixed, unchanging hydraulic head within the test zone. The varying flow rate required to maintain this head is tracked precisely over time. Technical and Equipment Requirements
