DIN EN ISO 14688-2:2013-12

This part of ISO 14688, together with ISO 14688-1, establishes the basic principles for the identification and description and classification of soils on the basis of those material and mass characteristics most commonly used for soils for engineering purposes. The relevant characteristics can vary and therefore, for particular projects or materials, more detailed subdivisions of the descriptive and classification terms can be appropriate. Identification and description of soil are covered by ISO 14688-1. The classification principles established in this part of ISO 14688 permit soils to be grouped into classes of similar composition and geotechnical properties and, with respect to their suitability for geotechnical engineering purposes, for example - foundations; - ground improvements; - roads; - dams; and - drainage systems. This part of ISO 14688 is applicable to natural soil and similar man-made material in situ and redeposited, but it is not a classification of soil by itself. Identification and description of rock are covered by ISO 14689-1. The committee responsible for this standard is NA 005-05-02 AA "Benennung, Beschreibung und Klassifizierung von Boden und Fels (SpA zu ISO/TC 182, ISO/TC 182/WG 1 und CEN/TC 341)" ("Identification, description and classification of soil and rock (SpA to ISO/TC 182, ISO/TC 182/WG 1 and CEN/TC 341)") at DIN.
