This standard is used in earthworks, waterworks and road works and serves as a basis for the identification and classification of soils (see DIN EN ISO 14688-1 and DIN 18196). This standard specifies 3 methods for determination of the grain-size distribution of soils. The grain-size distribution describes the soil on the basis of geometric expansion of its components and its mass fractions. It serves as a foundation for the assessment and application criteria of soils. It allows conclusions to be drawn about certain soil-mechanical characteristics. The Committee responsible for the standard is NA 005-05-03 AA "Baugrund; Laborversuche (SpA zu CEN/TC 341/WG 6)" ("Laboratory tests on soils (Mirror Committee of CEN/TC 341/WG 6)") at DIN.
