ISO 14688-2:2004 PDF Download

ISO 14688-2:2004 is a standard that provides the principles for the identification and classification of soil based on its characteristics and properties commonly used in engineering projects. This standard, together with ISO 14688-1, establishes a framework that allows for the grouping of soils into classes based on their composition, geotechnical properties, and suitability for geotechnical engineering purposes.

The standard acknowledges that the characteristics of soil may vary, and therefore, more detailed subdivisions of descriptive and classification terms may be necessary for specific projects or materials. It is important to note that ISO 14688-2:2004 is not a classification of soil in itself, but rather provides the principles for classification.

This standard is applicable to natural soil as well as man-made materials found in situ or redeposited. Its purpose is to provide a consistent and standardized approach to the identification and classification of soil, ensuring that engineers and researchers have a common language and understanding of soil properties for geotechnical purposes.
