土壤质量. 取样. 第102部分: 取样技术的选择和应用

[中文适用范围]： 本文件提供了采样技术指南，以便随后对采样进行检查，从而提供土壤质量信息。它提供了在特定采样情况下通常适用的设备信息，以便能够执行正确的采样程序并收集代表性样本。它提供了有关选择设备和使用的技术的指南，以便能够在不同深度正确采集受干扰和未受干扰的样本。本文件不涵盖： — 为岩土工程目的进行的调查，尽管在设想重新开发场地的情况下，土壤质量调查和岩土工程调查有时可以有益地结合起来； — 基岩等硬地层的采样； — 无需采样即可收集土壤质量信息的方法，例如地球物理方法； — 水样采集（这些水样应根据有关地下水或地表水采样的国际标准进行采集；有关更多信息，请参阅 ISO 5667 系列）； — 土壤气体调查，有关指南在 ISO 18400-204 中提供； — 放射性污染场地调查。注 1：“采样技术”在 ISO 11074 中定义。 注 2 ISO 18589 系列提供了有关土壤放射性调查和评估的指导。 [外文原描述]： ISO 18400-102:2017 gives guidelines for 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. ISO 18400-102:2017 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 are to be collected in accordance with appropriate International Standards on ground or surface water sampling; for further information, see the ISO 5667 series); - 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. NOTE 2 Guidance on the investigation and assessment of radioactivity in soils is provided in the ISO 18589 series.
