土壤质量.取样.第104部分：策略

[中文适用范围]： 本文档提供了关于开发场地调查策略的一般性指导，以及在收集土壤平均特性、土壤特性变异性和土壤特性空间分布信息时的采样策略的详细指导。它适用于旨在进行化学测试和测定各种其他特性（例如物理特性）的土壤样本。虽然本文档的主要重点是收集用于转移到实验室进行测试的现场材料，但它也适用于直接在现场进行的测量。 [外文原描述]： 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.
