DIN EN ISO 22475-1:2007-01

This part of ISO 22475 deals with the technical principles of sampling of soil, rock and groundwater, and with groundwater measurements in the context of geotechnical investigation and testing, as described in EN 1997-1 and EN 1997-2. The aims of such ground investigations are: a) to recover soil and rock samples of a quality sufficient to assess the general suitability of a site for geotechnical engineering purposes and to determine the required soil and rock characteristics in the laboratory; b) to obtain information on the sequence, thickness and orientation of strata and joint system and faults; c) to establish the type, composition and condition of strata; d) to obtain information on groundwater conditions and recover water samples for assessment of the interaction of groundwater, soil, rock and construction material.
