ISO 17892-1:2014规定了测定土壤含水量的方法。 本标准适用于在岩土工程勘察范围内通过烘箱干燥对土壤试样的含水量（也称为水分）进行实验室测定。要求将含水量作为天然土壤分类指南和再压实土壤的控制标准，并在大多数现场和实验室试验中使用的样品上进行测量。烘箱干燥法是通常实验室实践中使用的最终程序。 测定土壤含水量的实用程序是测定在给定温度下控制的干燥箱中将试样干燥至恒定质量时的质量损失。 假设质量损失是由自由水引起的，并参考固体颗粒的剩余干质量。

ISO 17892-1:2014 specifies a method of determining the water content of soils. It is applicable to the laboratory determination of the water (also known as moisture) content of a soil test specimen by oven-drying within the scope of geotechnical investigations. The water content is required as a guide to the classification of natural soils and as a control criterion in re-compacted soils, and is measured on samples used for most field and laboratory tests. The oven-drying method is the definitive procedure used in usual laboratory practice. The practical procedure for determining the water content of a soil is to determine the mass loss on drying the test specimen to a constant mass in a drying oven controlled at a given temperature. The mass loss is assumed to be due to free water and is referenced to the remaining dry mass of solid particles.
