This International Standard specifies laboratory methods for determination of the soil water-retention characteristic. This International Standard applies only to measurements of the drying or desorption curve. Four methods are described to cover the complete range of soil water pressures as follows: method using sand, kaolin or ceramic suction tables for determination of matric pressures from 0 kPa to - 50 kPa; method using a porous plate and burette apparatus for determination of matric pressures from 0 kPa to - 20 kPa; method using a pressurized gas and a pressure plate extractor for determination of matric pressures from - 5 kPa to - 1 500 kPa; method using a pressurized gas and pressure membrane cells for determination of matric pressures from - 33 kPa to - 1 500 kPa. Guidelines are given to select the most suitable method in a particular case.
