Geotechnical investigation and testing -- Identification and classification of rock -- Part 1: Identification and description
ISO 14689-1:2003 relates to the identification and description of rock material and mass on the basis of mineralogical composition, genetic aspects, structure, grain size, discontinuities and other parameters. It also provides rules for the description of other characteristics as well as for their designation.
ISO 14689-1:2003 applies to the description of rock for geotechnics and engineering geology in civil engineering. The description is carried out on cores and other samples of natural rock and on rock masses.
Rock mass classification systems using one or more descriptive parameters to suggest likely rock mass behaviour are not covered in ISO 14689-1:2003.
