NF EN ISO 22475-1

<p>This document deals with principles of sampling of soil, rock and groundwater as part of the programme of geotechnical investigation and testing.</p> <p>NOTE 1    This document fulfils the requirements for sampling of soil, rock and groundwater, and groundwater measurements as part of the programme of geotechnical investigation and testing according to EN 1997-1 and EN 1997-2.</p> <p>The aims of such ground investigations are:</p> <p>a) to recover soil, rock and water samples of a quality appropriate to assess the general suitability of a site for geotechnical engineering purposes and to determine the required ground characteristics in the laboratory;</p> <p>b) to obtain information on the sequence, thickness and orientation of strata and discontinuities;</p> <p>c) to establish the type, composition and condition of strata;</p> <p>d) to obtain information on groundwater conditions and recover water samples for assessment of the interaction of groundwater, soil, rock and construction material.</p> <p>Soil sampling for the purposes of agricultural and environmental soil investigation is not covered.</p> <p>NOTE 2    Guidance on soil sampling for these purposes including of contaminated or potentially contaminated sites is provided in the ISO 18400 series. ISO 18400-204 provides in addition guidance on sampling and measurement of soil (ground) gas.</p> <p>NOTE 3    The sampling methods, presented in this document may not be suitable for all types of soil e.g. peat with strong fibrous structure.</p> <p>NOTE 4    Some of the sampling methods presented in this document are suitable for both soil and rock.</p> <p>Water sampling for the purposes of quality control, quality characterisation and identification of sources of pollution of water, including bottom deposits and sludges, is not covered.</p> <p>NOTE 5    Water sampling for these purposes can be found in the ISO 5667 series.</p>
