ISO 22282-6

Description / Abstract: 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 i n l ow p ermeability s oil a nd r ock l ower t han 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.
