ISO 22282-6:2012 PDF

Scope: This part of ISO 22282 specifies requirements for the determination of the local permeability in soils and rocks below or above the groundwater table in a closed system by the water permeability tests as part of the geotechnical investigation services according to EN 1997-1 and EN 1997-2. The tests are used to determine the permeability coefficient k in low permeability soil and rock lower than 10 −8 m/s. It can also be used to determine the transmissivity T and the storage coefficient S. NOTE The water pressure test in rock is covered by ISO 22282-3.
