标准范围

ISO/TS 17892-1:2004规定了根据prEN 1997-1和prEN 1997-2，在岩土工程勘察范围内，通过烘箱干燥对土壤试样的水（水分）含量进行实验室测定。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，并在用于大多数现场和实验室试验的样品上进行测量。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，在给定温度下控制的干燥箱中，通过将潮湿土壤（试样）干燥至恒定质量来测定去除的水质量，并将该值用作与固体颗粒质量相关的试样中的水质量。烘箱干燥后剩余的土壤质量用作固体颗粒的质量。

ISO/TS 17892-1:2004 specifies the laboratory determination of the water (moisture) content of a soil test specimen by oven-drying within the scope of the geotechnical investigations according to prEN 1997-1 and prEN 1997-2. The water content is required as a guide to 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 of water removed by drying the moist soil (test specimen) to a constant mass in a drying oven controlled at a given temperature, and to use this value as the mass of water in the test specimen related to the mass of solid particles. The mass of soil remaining after oven-drying is used as the mass of the solid particles.
