This part of ISO 22282 establishes requirements for pumping tests as part of geotechnical investigation service in accordance with EN 1997-1 and EN 1997-2. A pumping test consists in principle of: - drawing down the piezometric surface of the groundwater by pumping from a well (the test well); - measuring the pumped discharge and the water level in the test well and piezometers, before, during and after pumping, as a function of time. This part of ISO 22282 applies to pumping tests performed on aquifers whose permeability is such that pumping from a well can create a lowering of the piezometric head within hours or days depending on the ground conditions and the purpose. It covers pumping tests carried out in soils and rock.
