Description of BS EN ISO 22475-1:2021 2021
This document deals with principles of sampling of soil, rock
and groundwater as part of the programme of geotechnical
investigation and testing.
NOTEÂ 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
ENÂ 1997-1 and
ENÂ 1997-2 .
The aims of such ground investigations are:
-
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;
-
to obtain information on the sequence, thickness and
orientation of strata and discontinuities;
-
to establish the type, composition and condition of
strata;
-
to obtain information on groundwater conditions and recover
water samples for assessment of the interaction of groundwater,
soil, rock and construction material.
Soil sampling for the purposes of agricultural and environmental
soil investigation is not covered.
NOTEÂ 2
Guidance on soil sampling for these purposes including of
contaminated or potentially contaminated sites is provided in the
ISOÂ 18400 series.
ISOÂ 18400-204 provides in addition guidance on
sampling and measurement of soil (ground) gas.
NOTEÂ 3
The sampling methods, presented in this document may not be
suitable for all types of soil e.g. peat with strong fibrous
structure.
NOTEÂ 4
Some of the sampling methods presented in this document are
suitable for both soil and rock.
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.
NOTEÂ 5
Water sampling for these purposes can be found in the
ISO 5667 series .
