BS EN ISO 14688-2:2004+A1:2013

This standard BS EN ISO 14688-2:2004+A1:2013 Geotechnical investigation and testing. Identification and classification of soil is classified in these ICS categories:

• 93.020 Earthworks. Excavations. Foundation construction. Underground works

This part of ISO 14688, together with ISO 14688-1, establishes the basic principles for the identification and classification of soils on the basis of those material and mass characteristics most commonly used for soils for engineering purposes. The relevant characteristics may vary and therefore, for particular projects or materials, more detailed subdivisions of the descriptive and classification terms may 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 c omposition and geotechnical p roperties and, with respect to t heir s uitability f or geotechnical engineering purposes, such as

• foundations,

• ground improvements,

• roads,

• embankments,

• 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.
