Geotechnical investigation and testing. Geohydraulic testing - Water permeability tests in a borehole using closed systems

BS EN ISO 22282-6:2012 Geotechnical investigation and testing. Geohydraulic testing. Water permeability tests in a borehole using closed systems

BS EN ISO 22282-6:2012 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 BS EN ISO 22282-3:2012

BS EN ISO 22282 consists of the following parts, under the general title Geotechnical investigation and testing — Geohydraulic testing:

Part 1: General rules

Part 2: Water permeability tests in a borehole using open systems

Part 3: Water pressure tests in rock

Part 4: Pumping tests

Part 5: Infiltrometer tests

Part 6: Water permeability tests in a borehole using closed systems
