This part of is 22282 covers the requirements for pumping tests carried out as part of a geotechnical reconnais ance mis ion in accordance with EN 1997-1 and EN 1997-2. In principle, a pumping test consis s of lowering the piezometric level of the water table by pumping from a well (test well), and measuring the pumped flow and the water level in the test well and the piezometers, before, during and after pumping, as a function of time. This part of is 22282 applies to pumping tests carried out on aquifer formations whose permeability is such that pumping from a well can create a r
