This International Standard specifies a laboratory method for the simultaneous determination in soils of the
unsaturated hydraulic conductivity and of the soil water-retention characteristic. It is applicable only to
measurement of the drying or desorption curve. Application of the method is restricted to soil samples which
are, as far as possible, homogeneous. The method is not applicable to soils which shrink in the range of matric
head h(m)=0 to h(m)= -800 cm.
The range of the determination of the conductivity depends on the soil type. It lies between matric heads of
approximately h(m)= -50 cm and h(m)= -700 cm.
The range of the determination of the water-retention characteristic lies between matric heads of approximately
h(m)=0 and h(m)= -800 cm.
