Soil quality - Determination of dry bulk density (ISO 11272:1998)
EN-ISO 11272 describes 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 has to be determined (excavation method, see 4.2, and clod method, see 4.3).
Bodenbeschaffenheit - Bestimmung der Trockenrohdichte (ISO 11272:1998)
Diese Internationale Norm beschreibt drei Verfahren für die Bestimmung der Trockenrohdichte von Böden, berechnet aus der Masse und dem Volumen einer Bodenprobe. Diese drei Verfahren umfassen die Trocknung und Wägung einer Bodenprobe, deren Volumen entweder bekannt ist (Stechzylinderverfahren, siehe 4.1) oder bestimmt werden muss (Aushubverfahren, siehe 4.2, und Klumpenverfahren, siehe 4.3).
Qualité du sol - Détermination de la masse volumique apparente sèche (ISO 11272:1998)
La CEI 61300-2-7:2013 décrit une méthode destinée à déterminer l'aptitude d'un dispositif à fibres optiques à supporter des conditions environnementales dans lesquelles peut intervenir un moment de flexion en cours d'utilisation, de stockage et/ou de transport. Cet essai a pour principal objectif de permettre l'observation des effets d'un moment de flexion. Le moment de flexion peut provoquer des effets de nature à affecter de manière importante le bon fonctionnement, à provoquer une perte de résistance physique et à causer des modifications d'autres propriétés mécaniques importantes. Une dégradation des propriétés optiques peut également se produire. Le spécimen peut être un composant, un jeu de connecteurs, une épissure ou une autre combinaison de dispositifs destinée à être utilisée avec des fibres optiques. Cette deuxième édition annule et remplace la première édition parue en 1995. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- un ré-examen complet de l'ensemble du document, y compris l'addition de nouvelles références normatives;
- la clarification du dispositif en essai (DUT);
- la clarification de la relation entre sévérités, les catégories de performance et le DUT.

Kakovost tal - Določevanje prostorninske gostote suhih vzorcev (ISO 11272:1998)
Standard EN-ISO 11272 opisuje 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 pa jo je treba določiti (metoda z izkopavanjem, glej točko 4.2, ali metoda grude, glej 4.3).

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.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 11272 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee
SC 5, Physical methods.
Annexes A and B of this International Standard are for information only.

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.

1 Scope
This International Standard describes 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 has to be determined (excavation method, see 4.2, and clod
method, see 4.3).
2 Normative reference
The following standard contains provisions which, through reference in this text, constitute provisions of this Inter-
national Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision,
and parties to agreements based on this International Standard are encouraged to investigate the possibility of
applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of
currently valid International Standards.
1)
ISO 10381-1: – , Soil quality — Sampling — Part 1: Guidance on the design of sampling programmes.
3 Definition
For the purposes of this International Standard, the following definition applies.
3.1 dry bulk density
Ratio of the oven-dry mass of the solids to the volume of the soil.
NOTE 1 The bulk volume includes the volume of the solids and of the pore space.
-3
NOTE 2 The preferred SI unit of measurement is kilograms per cubic metre (kg { m ) but grams per cubic centimetre
-3 -3 -3
(g { cm ) is also very common. Note that x g { cm = 1000 x kg { m .
4 Test procedure
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, weighed and the dry bulk density is calculated.

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 1/1000 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 (minimum 48 h). 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).
