ISO 18400-102:2017给出了采样技术指南，以便随后可以对这些技术进行检查，以提供土壤质量信息。它提供了通常适用于特定采样情况的设备信息，以便执行正确的采样程序并采集代表性样本。提供了选择设备和使用技术的指南，以便在不同深度正确采集扰动和未扰动样品。 ISO 18400-102:2017不包括: -出于岩土工程目的进行的调查，尽管在设想重新开发现场的情况下，土壤质量调查和岩土工程调查有时可能会有益地结合起来； -基岩等坚硬地层的取样； -在不采集样本的情况下收集土壤质量信息的方法，如地球物理方法； -水样的采集（这些水样将根据有关地下水或地表水采样的适当国际标准进行采集；有关更多信息，请参阅ISO 5667系列）； -ISO 18400-204中提供了指导的土壤气体调查； -放射性污染场所的调查。 注1:ISO 11074中定义了“取样技术”。 注2:ISO 18589系列中提供了土壤放射性调查和评估指南。

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.
