This Technical Specification (CEN/TS) was approved by CEN on 20 October 2003 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,
Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Introduction
This document covers areas in the international field of geotechnical engineering never previously standardised. 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 [1]).
1 Scope
This document specifies the laboratory determination of the water (moisture) content of a soil test specimen by
oven-drying within the scope of the geotechnical investigations according to prEN 1997-1 and prEN 1997-2. The
water content is required as a guide to classification of natural soils and as a control criterion in re-compacted soils
and is measured on samples used for most field and laboratory tests. The oven-drying method is the definitive
procedure used in usual laboratory practice.
The practical procedure for determining the water content of a soil is to determine the mass of water removed by
drying the moist soil (test specimen) to a constant mass in a drying oven controlled at a given temperature, and to
use this value as the mass of water in the test specimen related to the mass of solid particles. The mass of soil
remaining after oven-drying is used as the mass of the solid particles.
2 Normative references
The following referenced documents are indispensable for the application 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.
prEN 1997-1, Eurocode 7 - Geotechnical design — Part 1: General rules.
prEN 1997-2, Eurocode 7 - Geotechnical design — Part 2: Ground investigation and testing.
3 Terms and definitions
For the purposes of this document, the following term and definition apply.
3.1
water (moisture) content
w
the ratio of the mass of 'pore' or 'free' water in a given mass of soil material to the mass of the 'dry' solid soil
particles
NOTE In this context a soil is 'dry' when no further water can be removed at a temperature within the interval of
105 °C ± 5 °C.
4 Equipment
4.1 Drying oven
The drying oven shall be preferably of the forced-draft type, and capable of maintaining a uniform temperature of
105 °C ± 5 °C throughout the drying chamber. For ovens of the forced-draft type, the air circulation may not be so
strong that any transport of particles can take place.
4.2 Balance
The balance shall have an accuracy of
 ± 0,03 g for test specimens having a mass of 200 g or less,
 ± 0,3 g for test specimens having a mass of between 200 g and 1 000 g, or
 ± 3 g for specimens having a mass greater than 1 000 g.
NOTE The accuracy of the water content determined on balances conforming to above specifications corresponds to 3
significant digits.
4.3 Test specimen containers
4.3.1 Test specimen containers shall be made of material resistant to corrosion and change in mass upon
repeated heating, cooling and cleaning. A suitable number of the containers shall have close fitting lids. One
contain
