本国际标准旨在实现土壤样品现场记录、取样、现场样品分析和实验室分析报告结果的高度统一。为此，它提供了正确指定用于表示分析结果的数量和单位、所用方法及其精度的说明。本国际标准还提供了允许在现场和实验室环境中对样品进行唯一引用的信息，以确保结果的可追溯性。

The purpose of this International Standard is to achieve a high degree of harmonization in reporting results of on-site recording, sampling, on-site sample analyses and laboratory analyses of soil samples. To this end, it provides instructions for correctly specifying the quantities and units used to express results of analyses, the methods used and their precision. This International Standard also provides information to allow unique referencing of the sample, in both field and laboratory contexts, in order to ensure the traceability of the results.
