DESCRIPTION
BS EN ISO 22282-6:2012
This standard BS EN ISO 22282-6:2012 Geotechnical investigation and testing. Geohydraulic testing is classified in these ICS categories:
- 91.010.30 Technical aspects
- 93.020 Earthworks. Excavations. Foundation construction. Underground works
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.
