Soil quality - Determination of the water-retention characteristic - Laboratory methods (ISO 11274:2019)

This document specifies laboratory methods for determination of the soil water-retention characteristic.
This document applies only to measurements of the drying or desorption curve.
Four methods are described to cover the complete range of soil water pressures as follows:
a)    method using sand, kaolin or ceramic suction tables for determination of matric pressures from 0 kPa to −50 kPa;
b)    method using a porous plate and burette apparatus for determination of matric pressures from 0 kPa to −20 kPa;
c)    method using a pressurized gas and a pressure plate extractor for determination of matric pressures from −5 kPa to −1 500 kPa;
d)    method using a pressurized gas and pressure membrane cells for determination of matric pressures from −33 kPa to −1 500 kPa.
Guidelines are given to select the most suitable method in a particular case.

Bodenbeschaffenheit - Bestimmung des Wasserrückhaltevermögens - Laborverfahren (ISO 11274:2019)

Dieses Dokument legt Laborverfahren für die Ermittlung des Wasserrückhaltevermögens des Bodens fest.
Dieses Dokumentgilt nur für Messungen der Trocknungs- oder Desorptionskurve.
Vier Verfahren sind beschrieben, damit der gesamte Bereich der Bodenwasserdrücke wie folgt abgedeckt wird:
a) Verfahren, bei dem Sand-, Kaolin- oder Keramiksaugtische für die Ermittlung von Matrixdrücken von 0 kPa bis −50 kPa verwendet werden;
b) Verfahren, bei dem eine poröse Platte und Büretten-Apparatur für die Ermittlung von Matrixdrücken von 0 kPa bis −20 kPa verwendet werden;
c) Verfahren, bei dem ein Druckgas und Druckplattenextraktor für die Ermittlung von Matrixdrücken von −5 kPa bis −1 500 kPa verwendet werden;
d) Verfahren, bei dem ein Druckgas und Druckmembranzellen für die Ermittlung von Matrixdrücken von −33 kPa bis −1 500 kPa verwendet werden.
Anleitungen für die Auswahl des für den Einzelfall am besten geeigneten Verfahrens sind enthalten.

Qualité du sol - Détermination de la caractéristique de la rétention en eau - Méthodes de laboratoire (ISO 11274:2019)

Le présent document décrit les méthodes de laboratoire permettant de déterminer la caractéristique de rétention en eau du sol.
Le présent document s'applique uniquement aux mesurages effectués pour établir les courbes de séchage et de désorption.
Il existe quatre méthodes pour prendre en compte l'ensemble du domaine des pressions de l'eau des sols, à savoir:
a)    méthode utilisant des tables à succion à sable, kaolin ou céramique permettant de déterminer des pressions matricielles comprises entre 0 kPa et −50 kPa;
b)    méthode associant une plaque poreuse à un appareillage à burette permettant de déterminer des pressions matricielles comprises entre 0 kPa et −20 kPa;
c)    méthode utilisant un gaz sous pression et un extracteur à plaque poreuse permettant de déterminer des pressions matricielles comprises entre −5 kPa et −1 500 kPa;
d)    méthode utilisant un gaz sous pression et des cellules à membrane sous pression permettant de déterminer des pressions matricielles comprises entre −33 kPa et −1 500 kPa.
Des lignes directrices sont données pour faciliter le choix de la méthode la mieux adaptée à chaque cas particulier.

Kakovost tal - Določevanje karakteristik zadrževanja vode - Laboratorijske metode (ISO 11274:2019)

Ta standard določa laboratorijske metode za določevanje karakteristik zadrževanja vode v tleh. Ta dokument se uporablja samo za merjenje sušilne ali desorpcijske krivulje. Za zajem celotnega spektra vodnega tlaka v tleh so v standardu opisane naslednje štiri metode: a) metoda z uporabo sesalnih tabel iz peska, kaolina ali keramike za določanje matričnih tlakov od 0 do –50 kPa; b) metoda z uporabo porozne plošče in birete za določanje matričnih tlakov od 0 do –20 kPa; c) metoda z uporabo stisnjenega plina in tlačnega ekstraktorja za določanje matričnih tlakov od –5 kPa do –1500 kPa; d) metoda z uporabo stisnjenega plina in celic tlačne membrane za določanje matričnih tlakov od –33 do –1500 kPa. Podane so smernice za izbiro najprimernejše metode v posameznem primeru.
