It is intended that th

37、is part of ISO 17892 presents broad good practice throughout the world and significant differences with national documents is not anticipated. It is based on international practice (see Reference 2).DIN EN ISO 17892-4:2017-04 EN ISO 17892-4:2016 (E)5 1 ScopeThis part of ISO 17892 specifies a method

38、of determining the particle size distribution of soils.This part of ISO 17892 is applicable to the laboratory determination of the particle size distribution of a soil test specimen by sieving, or sedimentation, or a combination of both within the scope of geotechnical investigations.The particle si

39、ze distribution is one of the most important physical characteristics of soil. Classification of soils is mainly based on the particle size distribution. Many geotechnical and geohydrological properties of soil are related to the particle size distribution.The particle size distribution provides a d

40、escription of soil based on a subdivision in discrete classes of particle sizes. The size of each class can be determined by sieving and/or sedimentation. Coarse soils are usually tested by sieving, but fine and mixed soils are usually tested by a combination of sieving and sedimentation, depending

41、on the composition of the soil.The sieving method described is applicable to all non-cemented soils with particle sizes less than 125 mm. Two sedimentation methods are described: the hydrometer method and the pipette method.NOTE This part of ISO 17892 fulfils the requirements of the particle size di
