NF ISO 10381-1

<p>ISO 18400-107:2017 specifies the minimum information required for a sampling report independent of the purpose of the investigation.</p> <p>The preparation of the overall investigation report is not covered by this document (see ISO/IEC 17025:2005, 5.10.3).</p>

<p>This document gives general guidance on the development of site investigation strategies and detailed guidance on the development of sampling strategies, when collecting information on</p> <p>— the average properties of soil,</p> <p>— the variability of soil properties, and</p> <p>— the spatial distribution of soil properties.</p> <p>It is applicable to soil samples intended for chemical testing and determination of a variety of other properties (e.g. physical).</p> <p>Although the main focus of this document is the collection of material (field samples) for transfer to a laboratory for testing, it is also applicable when measurements are made directly in the field.</p> <p>NOTE 1 This document also provides information on the statistical principles underlying the development of appropriate sampling strategies and statistical methodologies.</p> <p>NOTE 2 Guidance on other forms of related sampling activities are given in other International Standards [for soil gas (ISO 18400-204) and for biological testing purposes (ISO 18400-206)]. 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.</p>
