Part 1 of BS EN ISO 14689 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.
It also 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 beyond the scope of this standard. Identification and classification of soil for engineering purposes is covered in BS EN ISO 14688-1 and BS EN ISO 14688-2.
