Geotechnical investigation and testing — Laboratory testing of soil — Part 3: Determination of particle density
ISO 17892-3:2015 specifies methods for the determination of the particle density of soils. ISO 17892-3:2015 is applicable to the laboratory determination of the particle density of soil within the scope of geotechnical investigations, and describes two methods, a pycnometer method by fluid displacement and a pycnometer method by gas displacement. The fluid pycnometer method described in this part of ISO 17892 applies to soil types with particle sizes under about 4 mm, or soils crushed to meet this requirement. Larger pycnometers are used for coarser materials. The particle size of soils suitable for testing in the gas pycnometer is limited by the dimensions of the specimen container of the particular gas pycnometer being used. NOTE 1 ISO 17892-3:2015 fulfils the requirements of the determination of particle density of soils for geotechnical investigation and testing in accordance with EN 1997-1 and EN 1997-2. NOTE 2 The presence of dissolved salts in the pore water can affect the results of these tests. Techniques for compensating for dissolved salts are available but are beyond the scope of this standard.
Reconnaissance et essais géotechniques — Essais de laboratoire sur les sols — Partie 3: Détermination de la masse volumique des particules solides
Cette partie de l'ISO 17892 spécifie des méthodes de détermination de la masse volumique des grains des sols. La présente partie de l'ISO 17892 s'applique à la détermination en laboratoire de la masse volumique des grains dans le cadre d'investigations géotechniques, et décrit deux méthodes : une méthode avec un pycnomètre à déplacement de liquide et une méthode avec un pycnomètre à déplacement de gaz. La méthode du pycnomètre à déplacement de liquide décrite dans la présente partie de l'ISO 17892 s'applique aux sols dont la dimension des particules est inférieure à environ 4 mm, ou aux sols broyés pour répondre à cette exigence. Des pycnomètres de plus grande taille sont utilisés pour les matériaux plus grossiers. La taille des particules de sols qui convient pour les essais réalisés dans le pycnomètre à gaz est limitée par les dimensions du récipient du pycnomètre à gaz en question. NOTE 1 La présente partie de l'ISO 17892 satisfait aux exigences de détermination de la masse volumique des particules de sols à des fins de reconnaissance et d'essais géotechniques, conformément aux normes EN 1997-1 et EN 1997-2. NOTE 2 La présence de sels dissous dans l'eau interstitielle peut affecter les résultats de ces essais. Des techniques de compensation des sels dissous existent, mais elles n'entrent pas dans le domaine d'application de la présente norme.

Introduction
This document covers areas in the international field of geotechnical engineering never previously standardised
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 [1]).
EN ISO 17892-3:2013(E)
1 Scope
This International Standard specifies methods for the determination of the particle density in soils.
This International Standard is applicable to the laboratory determination of the particle density of soil within the
scope of geotechnical investigations, and describes two methods, a pycnometer method by fluid displacement and
a pycnometer method by gas displacement.
The fluid pycnometer method is based on the determination of the difference in the volume of liquid required to fill
the pycnometer with and without the sample being present. The density of solid particles is calculated from the dry
mass of the soil particles and the volume difference. The described fluid pycnometer method applies to soil types
with particle sizes under about 4 mm, or soils crushed to meet this requirement. Larger pycnometers are used for
coarser materials.
The gas pycnometer method is based on the determination of the difference in the change in gas pressure, within
the apparatus, between tests with the sample present and a reference test without a sample. The pressure
difference is converted to a volume difference using Boyle’s Law. The density of the particles is calculated from the
dry mass of the sample and the volume difference. Particle size is limited by the dimensions of the specimen
container of the particular gas pycnometer being used.
NOTE This document fulfils the requirements of the determination of particle density of soils for geotechnical
investigation and testing in accordance with EN 1997-1 and EN 1997-2.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable
for its application. 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.
density of solid particles
ρ
s
mass of the particles divided by their volume.
4 Equipment
See Annex A for calibration requirements of the following equipment.
4.1 General
4.1.1 Balance
The balance shall have an accuracy of 0,01 g or 0,1% of the weighed soil mass, whichever is the greater.
EN ISO 17892-3:2013(E)
4.1.2 Dessicator
The desiccator, if used, shall be of suitable size and contain dry, self indicating desiccant such as silica gel. It is
not required if test specimen containers with close-fitting lids are used.
NOTE The purpose of the desiccator is to prevent absorption of moisture from air
4.1.3 Riffle box
A riffle box should be used to obtain a representative part of the specimen. Distribution by hand (quartering) is
also acceptable, if this results in a representative part of the specimen.
4.1.4 Drying oven
The drying oven should be of the forced-draft type and shall be capable of maintaining a uniform temperature
throughout the drying chamber. Any air circulation shall not be so strong that any transport of particles can take
place.
4.1.5 Sample crushing equipment
A mortar and soft-ended pestle (eg a pestle with a rubber or wooden tip) shall be used to break up dried soil
specimens. More substantial sample crushing equipment may be required to crush gravel sized rock particles.
4.2 Fluid displacement equipment
4.2.1 Fluid pycnometer
A fluid pycnometer shall have a volume of at least 50 ml, a glass stopper which has been ground to fit precisely,
and a capillary rising tube (see Figure 1).

EN ISO 17892-3:2013(E)
4.2.2 Water bath or temperature controlled enclosure or cabinet
A thermostatically controlled water bath, or a temperature controlled room or cabinet, with temperature variation
not exceeding ±0,5°C during the test shall be used.
4.2.3 Temperature measurement
A temperature measuring device accurate to 0,1°C shall be used. The temperature measuring device should
preferably be included in the glass stopper of the pycnometer. Alternatively, a temperature measuring device
may be placed in the water bath or in the temperature controlled enclosure/ room, as close to the pycnometer
as possible.
4.2.4 Apparatus to remove entrapped air
A vacuum pump or water aspirator that is capable of producing a partial vacuum may be used to remove air
from the sample during the test.
4.2.5 Control liquid
A control liquid of known or measured density is required to fill the pycnometer bottle. Distilled, demineralised or
deionised water is often the most suitable liquid. Alternatively a suitable organic solvent such as hexane or
kerosene may be used. Control liquids with a surface tension lower than that of water may be found to be
preferable to rapidly saturate fine soils.
NOTE Use of liquids other than water may cause health or safety hazards, or contravene national laws.
4.3 Gas displacement equipment
4.3.1 Gas pycnometer
A gas pycnometer system with sample and expansion chambers, isolation valves and a pressure gauge (see
Figure 2). Other equipment arrangements are permitted, with pressure measurement being on either chamber.
The pressure in the specimen chamber may be either increased or decreased on opening the isolation valve.
The chambers and valves shall be pressure-tight at the instrument’s working pressures.
The system shall be fitted with a pressure gauge with an accuracy of 0,1 kPa or 0,1% of the working pressure of
the gas pycnometer, whichever value is the greater.
For improved accuracy the sample chamber should have a volume not more than about two times that of the
sample, and the volumes of the sample and expansion chambers should not differ by more than a factor of
about three.

4.3.2 Compressed gas
Helium is preferred as the measurement gas. Other gasses that give good diffusion into soil pores may be used,
but this should be stated in the report. Unless otherwise specified as being acceptable by the gas pycnometer
equipment manufacturer, research grade (>99,5% purity) helium should be used in conjunction with the
instrument.

5 Test procedures
5.1 Fluid pycnometer method
5.1.1 Reference measurements
5.1.1.1 Determine the dry mass of the clean and dry pycnometer to the nearest 0,01 g or 0,1% of the
weighed soil mass, whichever is the greater (m ).
5.1.1.2 Fill the pycnometer with the control fluid so that no air shall be left in the pycnometer or capillary
tube.
5.1.1.3 Place the pycnometer in the water bath, or in the temperature controlled room or cabinet. Record
the temperature. If using a water bath, only the neck, the stopper and the capillary rising tube of the
pycnometer should emerge above the surface of the water in the bath. Leave the pycnometer in the water
bath until the control fluid temperature has become equal to that of the water bath – a

Introduction
Cette partie de l’ISO 17892 couvre des sujets n’ayant jusqu’alors pas été normalisés au niveau
international dans le domaine de la géotechnique. L’objectif de la présente partie de l’ISO 17892 est de
présenter la pratique généralement appliquée et il n’est pas indiqué les différences significatives avec
les documents nationaux. Celle-ci s’appuie sur une pratique internationale (voir la référence [1]).

Partie 3:
Détermination de la masse volumique des particules solides
1 Domaine d’application
Cette partie de l’ISO 17892 spécifie des méthodes de détermination de la masse volumique des grains
des sols.
La présente partie de l’ISO 17892 s’applique à la détermination en laboratoire de la masse volumique
des grains dans le cadre d’investigations géotechniques, et décrit deux méthodes : une méthode avec un
pycnomètre à déplacement de liquide et une méthode avec un pycnomètre à déplacement de gaz.
La méthode du pycnomètre à déplacement de liquide décrite dans la présente partie de l’ISO 17892
s’applique aux sols dont la dimension des particules est inférieure à environ 4 mm, ou aux sols broyés
pour répondre à cette exigence. Des pycnomètres de plus grande taille sont utilisés pour les matériaux
plus grossiers. La taille des particules de sols qui convient pour les essais réalisés dans le pycnomètre à
gaz est limitée par les dimensions du récipient du pycnomètre à gaz en question.
NOTE 1 La présente partie de l’ISO 17892 satisfait aux exigences de détermination de la masse volumique des
particules de sols à des fins de reconnaissance et d’essais géotechniques, conformément aux normes EN 1997-1 et
EN 1997-2.
NOTE 2 La présence de sels dissous dans l’eau interstitielle peut affecter les résultats de ces essais. Des
techniques de compensation des sels dissous existent, mais elles n’entrent pas dans le domaine d’application de la
présente norme.
