This International Standard specifies a basic method of determining the particle size distribution applicable to a wide range of mineral soil materials, including the mineral fraction of organic soils. It also offers procedures to deal with the less common soils mentioned in the introduction. This International Standard has been developed largely for use in the field of environmental science, and its use in geotechnical investigations is something for which professional advice might be required.A major objective of this International Standard is the determination of enough size fractions to enable the construction of a reliable particle-size-distribution cu
