Geotechnical investigation and testing - Laboratory testing of soil - Part 3: Determination of particle density (ISO 17892-3:2015, Corrected version 2015-12-15)

This document describes a test method for determining the particle density by the pycnometer method.
The pycnometer method is based on the determination of the volume of a known mass of soil by the fluid displacement method. The density of solid particles is calculated from the mass of the soil and the volume. The pycnometer method applies to soil types with particle sizes under 4 mm.

Geotechnische Erkundung und Untersuchung - Laborversuche an Bodenproben - Teil 3: Bestimmung der Korndichte (ISO 17892-3:2015)

Diese Internationale Norm legt Verfahren zur Bestimmung der Korndichte von Böden fest.
Diese Internationale Norm ist im Rahmen geotechnischer Untersuchungen auf die labortechnische Bestimmung der Korndichte von Boden anwendbar und beschreibt zwei Verfahren: ein Pyknometer-Verfahren mittels Flüssigkeitsverdrängung und ein Pyknometer-Verfahren mittels Gasverdrängung.
Das Pyknometer-Flüssigkeitsverfahren beruht auf der Bestimmung des Volumenunterschieds der zum Füllen des Pyknometers erforderlichen Flüssigkeit bei enthaltenem und bei nicht enthaltenem Prüfmuster. Die Korndichte wird aus der Trockenmasse der Bodenteilchen und dem Volumenunterschied berechnet. Das beschriebene Pyknometer-Flüssigkeitsverfahren ist anwendbar bei Bodenarten mit einem Korndurchmesser von weniger als etwa 4 mm oder auf Böden, die zerkleinert wurden, um den Anforderungen zu entsprechen. Bei gröberen Materialien werden größere Pyknometer eingesetzt.
Das Pyknometer-Gasverfahren beruht auf der Bestimmung des Unterschieds bei der Änderung des Gasdrucks innerhalb des Geräts zwischen Versuchen mit Prüfmuster und einem Referenzversuch ohne  Prüfmuster. Unter Anwendung des Boyle-Mariott-Gesetzes wird der Druckunterschied in einen Volumenunterschied umgerechnet. Die Korndichte wird aus der Trockenmasse des Prüfmusters und dem Volumenunterschied berechnet. Die Korngröße wird durch die Maße des Probenbehälters des speziellen Gaspyknometers, der verwendet wird, begrenzt.
ANMERKUNG   Dieses Dokument erfüllt die Anforderungen an die Bestimmung der Korndichte von Böden bei der geo¬technischen Erkundung und Untersuchung nach EN 1997-1 und EN 1997-2.

Reconnaissance et essais géotechniques - Essais de laboratoire sur les sols - Partie 3: Détermination de la masse volumique des grains (ISO 17892-3:2015)

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.

Geotehnično preiskovanje in preskušanje - Laboratorijsko preskušanje zemljin - 3. del: Ugotavljanje gostote zrn (ISO 17892-3:2015)

Ta dokument opisuje preskusno metodo za ugotavljanje gostote zrn z metodo piknometra.
Metoda piknometra temelji na ugotavljanju volumna znane mase zemljine z metodo izpodrivanja tekočin. Gostota trdnih delcev se izračuna iz mase zemljine in volumna. Metoda piknometra velja za vse vrste zemljin z velikostjo zrn manj kot 4 mm.

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).

Introduction
This part of ISO 17892 covers areas in the international field of geotechnical engineering never
previously standardized internationally. It is intended that this part of ISO 17892 presents broad
good practice and significant differences with national documents is not anticipated. It is based on
international practice (see Reference [1]).

Part 3:
Determination of particle density
1 Scope
This part of ISO 17892 specifies methods for the determination of the particle density of soils.
This part of ISO 17892 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 This part of ISO 17892 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.

4.2 General
4.2.1 Balance, shall have an accuracy of 0,01 g or 0,1 % of the weighed soil mass, whichever is greater.
4.2.2 Dessicator, 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.
4.2.3 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.
4.2.4 Drying oven, of the forced-draught 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.
4.2.5 Sample crushing equipment, a mortar and soft-ended pestle (e.g. 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.
4.3 Fluid displacement equipment
4.3.1 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).
