Geotechnical investigation and testing. Laboratory testing of soil - Determination of particle size distribution1 Scope This part of ISO 17892 specifies a method 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 size distribution is one of the most important physical characteristics of soil. Classification of soils

the pressure loss coefficient inaccuracy is higher than the pressure loss caused by the test tubes

product specific standards

BS 4655 is primarily intended for plain velvets or patterned velvets containing a pile of uniform height

The data given in PD CEN/TR 16435 are based on the properties of pure chemical products and demonstrate the relationship between the concentration of oxygenated blending components and oxygen content in petrol

the methodology may be used correspondingly for any single- or multi-phase equipment covered by this technical report

The descriptions are from a functional point of view and not including requirements

The scope is limited to soils that exhibit free-draining behaviour during and after placement

EN 352-2 deals with requirements for ear-plugs
