Foreword
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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
patent declarations received (see www.iso.org/patents).

Introduction
This document covers areas in the international field of geotechnical engineering never previously
standardized internationally. It is intended that this document presents broad good practice throughout the
world and significant differences with national documents is not anticipated. It is based on international
practice (see Reference [1]).

DRAFT International Standard ISO/DIS 16383-1:2024(en)
Geotechnical investigation and testing — Laboratory testing

Part 1:
Determination of water content
1 Scope
This International Standard specifies a method of determining the water content of rocks.
This International Standard 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 in accordance with PrEN 1997-2 (2023).
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content constitutes
requirements of this document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

ratio of the mass of free water to the mass of the dry test specimen
3.2
constant mass
constant mass is regarded as the point at which there is less than 0.1 % further change in mass of the dry
rock test specimen when dried for a further period of at least 1 h, over three consecutive measurements (m’,
m’’, m’’’ according to Figure 1). When the sample is weighed in hot state, an insulation shall be provided between
the sample and the scale. The weight of the insulation device shall be accounted for.
