ISO/TS 17892-11:2004用于土方工程和基础工程。它规定了确定水通过饱和土壤渗透系数的实验室试验方法。在拟定的实验室试验中，土壤样本经受流经样本的水流。测量通过试样的水压条件和水量，以评估渗透性。所得结果可用于计算地下水流量，并评估人造防渗层和过滤层的渗透性。

ISO/TS 17892-11:2004 is intended for use in earthworks and foundation engineering. It specifies laboratory test methods to establish the coefficient of permeability of water through water-saturated soils. In the proposed laboratory tests soil specimens are subjected to a flow of water passing through the specimen. The water pressure conditions and volume of water passing through the specimens are measured for evaluation of the permeability.The results obtained serve to calculate groundwater flow and to assess the permeability of man-made impervious layers and filter layers.
