Geotechnical investigation and testing - Laboratory testing of rock - Part 1: Determination of water content (ISO 16383-1:2025)
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.
Geotechnische Erkundung und Untersuchung - Laborversuche an Felsproben - Teil 1: Bestimmung des Wassergehalts (ISO 16383-1:2025)
Dieses Dokument legt ein Verfahren zur Bestimmung des Wassergehalts von Gesteinen fest.
Dieses Dokument ist anwendbar für die Bestimmung des Wassergehalts von Gesteinsproben durch Ofentrocknung im Labor im Rahmen geotechnischer Untersuchungen. Die Ofentrocknung ist das in der Laborpraxis übliche Verfahren.
Die Bestimmung des Wassergehalts von Gestein besteht in der Ermittlung des Masseverlusts, der beim Trocknen der Probe bis zur Massenkonstanz bei festgelegter Temperatur im Trocknungsofen eintritt. Der Masseverlust wird dem freien Wasser zugeschrieben und in Bezug zur verbleibenden Trockenmasse der Probe gesetzt.
ANMERKUNG Dieses Dokument erfüllt die Anforderungen an die Bestimmung des Wassergehalts von Gestein im Rahmen von geotechnischen Erkundungen und Untersuchungen nach EN 1997 2.
Reconnaissance et essais géotechniques - Essais de laboratoire sur les roches - Partie 1: Détermination de la teneur en eau (ISO 16383-1:2025)
Le présent document traite du mode opératoire pour déterminer la teneur en eau des roches.
Le présent document spécifie les conditions pour la détermination en laboratoire de la teneur en eau d'une éprouvette de roche par séchage à l'étuve dans le domaine de la reconnaissance géotechnique. La méthode de séchage à l'étuve est la méthode de référence utilisée dans la pratique courante des laboratoires.
Le mode opératoire permettant de définir la teneur en eau d'une roche consiste à déterminer la perte de masse par dessiccation de l'éprouvette jusqu'à l’obtention d'une masse constante dans une étuve de séchage asservie à une température donnée. On considère que la perte de masse est due à l'eau libre, et elle est mise en relation avec la masse sèche restante de l'éprouvette.
NOTE Le présent document est conforme aux exigences relatives à la détermination de la teneur en eau des roches dans le cadre de la reconnaissance et des essais géotechniques, spécifiées dans la norme EN 1997-2.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
