本文件为现场调查策略的制定提供了一般指导，并在收集相关信息时为采样策略的制定提供了详细指导 -土壤的平均性质， -土壤性质的可变性，以及 -土壤性质的空间分布。 它适用于用于化学测试和各种其他性质（如物理性质）测定的土壤样品。 尽管本文件的主要重点是收集材料（现场样品），以便转移到实验室进行测试，但当直接在现场进行测量时，本文件也适用。 注1:本文件还提供了有关制定适当抽样策略和统计方法所依据的统计原则的信息。 注2:其他国际标准[土壤气体（ISO 18400-204）和生物测试（ISO 18400-206）]中给出了有关其他形式相关取样活动的指南。ISO 5667-11和ISO 5667-22提供了地下水采样指南，ISO 22475提供了岩土工程勘察中的采样方法和地下水测量指南- 1.

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 — the average properties of soil, — the variability of soil properties, and — the spatial distribution of soil properties. It is applicable to soil samples intended for chemical testing and determination of a variety of other properties (e.g. physical). 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. NOTE 1 This document also provides information on the statistical principles underlying the development of appropriate sampling strategies and statistical methodologies. 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.
