ISO 17313:2004规定了使用柔性壁渗透计在实验室测量水饱和多孔材料的水力传导率的测试方法。 ISO 17313:2004适用于水力传导率在1 × 10-5米/秒（1 × 10-3厘米/秒）和1 × 10-11米/秒（1 × 10-9厘米/秒）之间的未扰动或压实试样。属于这一类的典型土壤类型有粘土、粘土和沙壤土、淤泥、泥炭、淤泥等。

ISO 17313:2004 specifies a test method for laboratory measurement of the hydraulic conductivity of water-saturated porous materials using a flexible wall permeameter. ISO 17313:2004 is applicable to undisturbed or compacted specimens that have a hydraulic conductivity between 1 x 10^-5 m/s (1 x 10^-3 cm/s) and 1 x 10^-11 m/s (1 x 10^-9 cm/s). Typical soil types falling in this category are clay, clay and sand tills, silt, peat, mud, etc.
