ABSTRACT
This subdivision has been made to describe accurately the desorption isotherm at high moisture potentials. The equivalent pore radius indicates up to which size the capillary pores are filled with water. The transition of definition of the moisture potential is at 0.9, which corresponds with an equivalent pore radius of 10"^ m. The relative humidity is defined as:
CP - ^ (4) Pa
where p: vapour pressure in Pa, Pg: saturated vapour pressure in Pa.
