DANSK DSF/ISO/FDIS 18400-104 PDF

This International Standard provides general guidance on the development of site investigation strategies and detailed guidance on the development of sampling strategies, when information is required about: − the average properties of soil, – the variability of soil properties, and – the spatial distribution of soil properties. It is applicable when soil samples are required for chemical testing and determination of a variety of other properties (e.g. physical). Although the discussion is largely in terms of collection of material (field samples) for transfer to a laboratory for testing, this standard is also applicable when measurements are made directly in the field. NOTE 1 – This International Standard also provides information on the statistical principles underlying the development of appropriate sampling strategies and statistical methodologies that may be used. NOTE 2 – Guidance on other forms of related sampling activities are given in other International Standards (e.g. for soil gas ISO 18400-204) and biological testing purposes (ISO 10381-6). Guidance on sampling groundwater is provided in ISO 5667-11 and ISO 5667-22 and on sampling methods and groundwater measurements in geotechnical investigations in ISO 22475-1.
