DIN ISO 18400-104:2016-12

This Draft 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 draft standard is also applicable when measurements are made directly in the field. This Draft International Standard also provides information on the statistical principles underlying the development of appropriate sampling strategies and statistical methodologies that may be used.
