ISO 22282-4:2012 PDF Download

ISO 22282-4:2012 is a standard that establishes requirements for conducting pumping tests as part of geotechnical investigations. It is aligned with the European standards EN 1997-1 and EN 1997-2, which deal with geotechnical design and safety considerations.

The standard specifically applies to pumping tests conducted on aquifers with permeability levels that allow for a quick change in the piezometric head (the level at which water stands in a well or borehole) within a few hours or days. This timeframe depends on the characteristics of the ground and the objectives of the test. The standard covers pumping tests performed in both soil and rock formations.

The primary objective of the tests outlined in ISO 22282-4:2012 is to evaluate the hydrodynamic parameters of an aquifer, such as its permeability and porosity, along with the parameters related to the well itself. These tests play a crucial role in assessing the groundwater flow characteristics and providing valuable information for geotechnical analysis and design considerations.
