Description / Abstract:

This part of ISO 18400 provides guidance on techniques for taking samples so that these can subsequently be examined for the purpose of providing information on soil quality. It gives information on equipment that is typically applicable in particular sampling situations to enable correct sampling procedures to be carried out and representative samples to be collected. Guidance is given on the selection of the equipment and the techniques to use to enable both disturbed and undisturbed samples to be correctly taken at different depths.

The techniques for sampling stockpiles differ to some extent from those used to sample in-situ soils. The sampling of stockpiles is therefore dealt with separately in ISO 18400-20X.

This part of ISO 18400 does not cover:

— investigations for geotechnical purposes, though where redevelopment of a site is envisaged the soil quality investigation and the geotechnical investigation may sometimes be beneficially combined;

— sampling of hard strata such as bedrock;

— methods for the collection of information on soil quality without taking samples, such as geophysical methods;

— collection of water samples (these should be collected in accordance with appropriate International Standards on ground or surface water sampling - for further information see the ISO 5667 series of standards);

— investigations of soil gas about which guidance is provided in ISO 18400-204;

— investigation of radioactively contaminated sites.

NOTE 1 "Sampling technique" is defined in ISO 11074 as "all appropriate procedures and sampling devices to obtain and describe samples of soil or soil material, either in the field or during transportation or in the laboratory".

NOTE 2 ISO 22475-1 specifies the technical principles for the execution of sampling and groundwater measurements for geotechnical purposes. It describes and provides guidance on the application of many of the sampling techniques included in this standard albeit in a different context. Many contractors engaged to carry out work in connection with environmental studies will be familiar with its, often prescriptive, requirements. It includes detailed design information for some equipment.

NOTE 3 Guidance on the investigation and assessment of radioactivity in soils is provided in the ISO 18589 series of standards.
