Soil quality - Determination of particle density (ISO 11508:2017)
ISO 11508:2017 specifies two methods for the determination of particle density of soils calculated from the mass and the volume of soil particles.
The first method (4.1) is applicable to fine soil (<2 mm diameter) and the second method (4.2) is applicable to both porous and nonporous gravel and stones (>2 mm diameter).
The particle density can be used for the calculation of the proportion of solids and of the porosity of soil layers in combination with the procedure given in ISO 11272.
Bodenbeschaffenheit - Bestimmung der Kornrohdichte (ISO 11508:2017)
Diese Internationale Norm legt zwei Verfahren zur Bestimmung der Kornrohdichte von Böden mittels Berechnung aus der Masse und dem Volumen von Bodenpartikeln, fest.
Das erste Verfahren (4.1) ist anwendbar auf Feinboden (< 2 mm Durchmesser), und das zweite Verfahren (4.2) ist anwendbar auf Böden, mit porösen und nichtporösen Kies- und Steinanteil (> 2 mm Durchmesser).
Die Kornrohdichte kann zur Berechnung des Anteils fester Substanz und der Porosität von Bodenschichten in Verbindung mit dem Verfahren nach ISO 11272 verwendet werden.
Qualité du sol - Détermination de la masse volumique des particules (ISO 11508:2017)
ISO 11508:2017 spécifie deux méthodes permettant de déterminer la masse volumique des particules qui constituent les sols, à partir de la masse et du volume de ces dernières.
La première méthode (4.1) est utilisable pour la terre fine (de diamètre <2 mm), et la seconde méthode (4.2) est utilisable pour les graviers et cailloux (de diamètre >2 mm) poreux ou non poreux.
La masse volumique des particules peut être utilisée, conjointement avec le mode opératoire spécifié dans l'ISO 11272, pour calculer la fraction de matière solide et la porosité des couches de sol.
Kakovost tal - Določevanje gostote delcev (ISO 11508:2017)
Ta dokument določa dve metodi za določevanje gostote delcev tal, ki se izračuna iz mase in prostornine delcev tal.
Prva metoda (4.1) se uporablja za drobnozrnata tla (premer < 2 mm), druga (4.2) pa se uporablja za porozen in neporozen gramoz ter kamenje (premer > 2 mm).
Gostota delcev se v kombinaciji s postopkom iz standarda ISO 11272 lahko uporabi za izračun deleža trdih delcev in poroznosti plasti tal.

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).
