Soil quality - Determination of dry bulk density (ISO 11272:2017)
This document specifies three methods for the determination of dry bulk density of soils calculated
from the mass and the volume of a soil sample. The methods involve drying and weighing a soil sample,
the volume of which is either known [core method (see 4.1)] or determined [excavation method (see 4.2)
and clod method (see 4.4)].
Bodenbeschaffenheit - Bestimmung der Trockenrohdichte (ISO 11272:2017)
Dieses Dokument legt drei Verfahren für die Bestimmung der Trockenrohdichte von Böden, berechnet aus der Masse und dem Volumen einer Bodenprobe, fest. Diese Verfahren umfassen die Trocknung und Wägung einer Bodenprobe, deren Volumen entweder bekannt ist (Stechzylinderverfahren [siehe 4.1]) oder bestimmt wird (Aushubverfahren [siehe 4.2], und Klumpenverfahren [siehe 4.4]).
Qualité du sol - Détermination de la masse volumique apparente sèche (ISO 11272:2017)
ISO 11272:2017 spécifie trois méthodes de calcul de la masse volumique apparente sèche des sols à partir de la masse et du volume d'un échantillon de sol. Les méthodes consistent à sécher et peser un échantillon de sol, de volume connu [méthode du cylindre, (voir 4.1)] ou dont le volume est déterminé [(méthode par excavation (voir 4.2) et méthode des mottes (voir 4.4)].
Kakovost tal - Določevanje prostorninske gostote suhih vzorcev (ISO 11272:2017)
Ta dokument določa tri metode za določevanje prostorninske gostote suhih vzorcev, ki se izračuna iz mase in prostornine vzorca tal. Metode vključujejo sušenje in tehtanje vzorca tal, čigar prostornina je znana (metoda jedra (glej 4.1)) ali določena (metoda z izkopavanjem (glej 4.2) ali metoda grude (glej 4.4)).

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.

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
The dry bulk density is used together with the particle density (see ISO 11508) for the calculation of the
solids content and porosity of soil for the evaluation of soil structure and conversion of concentrations
of substances in soil from mass/volume to mass/mass and vice versa.

Soil quality — Determination of dry bulk density
1 Scope
This document specifies three methods for the determination of dry bulk density of soils calculated
from the mass and the volume of a soil sample. The methods involve drying and weighing a soil sample,
the volume of which is either known [core method (see 4.1)] or determined [excavation method (see 4.2)
and clod method (see 4.4)].

4 Test procedures
4.1 Core method
4.1.1 Principle
This method is applicable to stoneless and slightly stony soils. Core samples of known volume are taken
with a metal sampling tool. The sample is dried in an oven and weighed, and the dry bulk density is
calculated.
4.1.2 Apparatus
3 3
4.1.2.1 Core sample holders, thin-walled metal cylinders with a volume of 100 cm to 400 cm , a
steel cap for driving into the soil, and a driver.
4.1.2.2 Oven, heated and ventilated, capable of maintaining a temperature of (105 ± 2) °C.
4.1.2.3 Desiccator, sealed chamber in which the air is kept dry with the aid of silica gel or other
desiccant.
4.1.2.4 Laboratory balance, capable of weighing to an accuracy of 1/1 000 of the measured value.
4.1.3 Sampling and drying
Press or drive a core sample holder (4.1.2.1) of known volume without deflection and compaction into
either a vertical or horizontal soil surface far enough to fill the sampler. Carefully remove the sample
holder and its contents to preserve the natural structure, and trim the soil extending beyond each end
of the sample holder with a straight-edged knife or sharp spatula. The soil sample volume is thus equal
to the volume of the sample holder. Take at least six core samples from each soil layer. Place the holders
containing the samples in an oven (4.1.2.2) at 105 °C until constant mass is reached.
NOTE 1 In most cases, constant mass is reached after 48 h drying.
Remove the samples from the oven and allow them to cool in the desiccator (4.1.2.3). Weigh the samples
on the balance (4.1.2.4) immediately after removal from the desiccator (m ). Control mass is reached
t
when the differences in successive weighings of the cooled sample, at intervals of 4 h, d
