This document specifies a method of determining the water content of rocks.

This document is applicable to the laboratory determination of the water content of a rock test specimen by oven-drying within the scope of geotechnical investigations. The oven-drying method is the definitive procedure used in usual laboratory practice.

The practical procedure for determining the water content of a rock is to determine the mass loss on drying the test specimen to a constant mass in a drying oven controlled at a given temperature. The mass loss is assumed to be due to free water and is referenced to the remaining dry mass of the test specimen.

NOTE - This document fulfils the requirements of the determination of water content of rock for geotechnical investigation and testing according to EN 1997-2
