Soil quality - Leaching procedures for subsequent chemical and ecotoxicological testing of soil and soil materials - Part 3: Up-flow percolation test (ISO/TS 21268-3:2007)
ISO/TS 21268-3:2007 specifies a test, which is aimed at determining the leaching behaviour of inorganic and organic constituents from a soil and soil material. The method is a once-through percolation test with water (0,001 mol/l CaCl2) under standardized conditions of flow rate. The material is leached under dynamic hydraulic conditions. The eluates obtained can be used to determine the ecological properties of the soil with respect to micro-organisms, flora and fauna. The test results enable the distinction between different release patterns, for instance wash-out and release under the influence of interaction with the matrix, when approaching local equilibrium between material and leachant.
This test method produces eluates, which can subsequently be characterised by physical, chemical and ecotoxicological methods in accordance with existing standard methods. The results of eluate analysis are presented as a function of the liquid/solid ratio. The test is not suitable for species that are volatile under ambient conditions.
The application of this test method alone is not sufficient for the determination of the leaching behaviour of a material under specified conditions different to those from the test procedure, since this generally requires the application of several test methods, behavioural modelling and model validation. ISO/TS 21268-3:2007 does not address issues related to health and safety. It only determines the leaching properties as outlined in Clause 4.
Bodenbeschaffenheit - Eluierungsverfahren für die anschließende chemische und ökotoxikologische Untersuchung von Boden und von Bodenmaterialien - Teil 3: Perkolationstest im Aufwärtsstrom (ISO/TS 21268-3:2007)
Dieser Teil von ISO/TS 21268 legt eine Prüfung fest, deren Ziel die Bestimmung des Auslaugungsverhaltens von anorganischen und organischen Bestandteilen aus Böden und Bodenmaterialien ist. Bei dem Verfahren handelt es sich um eine Perkolationsprüfung mit einmaligem Durchlaufen von Wasser (0,001 mol/l CaCl2) unter genormten Bedingungen der Fließgeschwindigkeit. Das Material wird unter hydraulisch dynamischen Bedingungen ausgelaugt. Die erhaltenen Eluate können zur Bestimmung der ökologischen Eigenschaften des Bodens in Bezug auf Mikroorganismen, Fauna und Flora verwendet werden. Die Prüfergebnisse ermöglichen die Unterscheidung zwischen verschiedenen Freisetzungsmustern, wie z. B. Auswaschung und Freisetzung unter Einfluss einer Wechselwirkung mit der Matrix, wenn eine Annäherung an das örtliche Gleichgewicht zwischen Material und Auslaugungsmittel erfolgt.
Durch das vorliegende Prüfverfahren werden Eluate hergestellt, die anschließend mit physikalischen, chemi-schen und ökotoxikologischen Verfahren nach bestehenden Standardverfahren charakterisiert werden kön-nen. Die Ergebnisse der Eluatanalyse werden als Funktion des Flüssigkeits /Feststoffverhältnisses darge-stellt. Die Prüfung ist nicht geeignet für Spezies, die unter Umgebungsbedingungen flüchtig sind.
ANMERKUNG 1 Zu den flüchtigen organischen Bestandteilen gehören niedermolekulare Komponenten in Mischun¬gen, wie z. B. Mineralöl.
ANMERKUNG 2 Es ist nicht immer möglich, die Prüfbedingungen gleichzeitig für anorganische und organische Bestandteile zu optimieren und die optimalen Prüfbedingungen können sich auch für unterschiedliche Gruppen von organischen Bestandteilen unterscheiden. Die Prüfanforderungen für organische Bestandteile sind im Allgemeinen stren¬ger als für anorganische Bestandteile. Die Prüfbedingungen, die für die Messung der Freisetzung von organischen Bestandteilen geeignet sind, sind im Allgemeinen auch auf anorganische Bestandteile anwendbar.
ANMERKUNG 3 Für ökotoxikologische Untersuchungen sind Eluate erforderlich, die die Freisetzung sowohl von anorganischen als auch von organischen Schadstoffen widerspiegeln. Im vorliegenden Dokument umfasst die öko¬toxikologische Untersuchung auch die gentoxikologische Untersuchung.
Die Anwendung dieses Prüfverfahrens ist allein nicht ausreichend, um das Auslaugungsverhalten eines Mate¬rials unter festgelegten Bedingungen, die sich von denen in diesem Prüfverfahren unterscheiden, zu bestim¬men, da das im Allgemeinen die Anwendung mehrerer Prüfverfahren, die Aufstellung von Verhaltens-modellen und deren Validierung erfordert. Dieser Teil von ISO/TS 21268 befasst sich nicht mit gesund-heitlichen und sicherheitstechnischen Belangen. Er dient nur der Bestimmung der in Abschnitt 4 dargestellten Auslaugungs¬eigenschaften.
Qualité du sol - Modes opératoires de lixiviation en vue d'essais chimiques et écotoxicologiques ultérieurs des sols et matériaux du sol - Partie 3: Essai de percolation à écoulement ascendant (ISO/TS 21268-3:2007)
L'ISO/TS 21268-3:2007 spécifie un essai destiné à déterminer le comportement à la lixiviation de constituants inorganiques et organiques issus de sols et de matériaux du sol. La méthode est un essai de percolation mené en une fois avec de l'eau (0,001 mol/l CaCl2) dans des conditions de débit normalisées. Le matériau est lixivié dans des conditions hydrauliques dynamiques. Les éluats obtenus peuvent être utilisés pour déterminer les propriétés écologiques du sol par rapport aux microorganismes, à la flore et à la faune. Les résultats de l'essai permettent de faire la distinction entre différents relargages type, tels que le lessivage ou le relargage sous l'effet de l'interaction avec la matrice, à l'approche de l'équilibre local entre le matériau et le lixiviant.
Cette méthode d'essai produit des éluats qui peuvent ensuite être caractérisés par des méthodes physiques, chimiques et écotoxicologiques selon des méthodes normalisées existantes. Les résultats de l'analyse des éluats sont présentés en fonction du rapport liquide/solide. Cet essai n'est pas adapté aux espèces qui sont volatiles dans des conditions ambiantes.
L'application de la présente méthode d'essai seule ne suffit pas pour déterminer le comportement à la lixiviation d'un matériau dans des conditions spécifiées différentes de celles applicables au mode opératoire, car cela nécessite généralement l'application de plusieurs méthodes d'essai, d'une modélisation comportementale et d'une validation du modèle. L'ISO/TS 21268-3:2007 ne traite pas des questions liées à la santé et à la sécurité. Elle permet uniquement de déterminer les propriétés de lixiviation.
Kakovost tal - Postopki izluževanja za nadaljnje kemijsko in ekotoksikološko preskušanje tal in talnih (zemeljskih) materialov - 3. del: Preskus v koloni s tokom navzgor (ISO/TS 21268-3:2007)
Ta del ISO/TS 21268 opredeljuje preskus, katerega cilj je določiti odziv neorganskih in organskih sestavin iz tal in talnih (zemeljskih) materialov na izluževanje. Ta metoda je enkratno izveden preskus v koloni z vodo (0,001 mol/l CaCl2) pod standardiziranimi pogoji pretoka. Material se izlužuje pod dinamičnimi hidravličnimi pogoji. Pridobljeni izlužki se lahko uporabijo za določevanje ekoloških lastnosti tal v zvezi z mikroorganizmi, floro in favno. Preskusni rezultati omogočajo razlikovanje med različnimi vzorci sproščanja, na primer izpiranje in sproščanje pod vplivom interakcije z matrico pri približevanju lokalnemu ravnovesju med materialom in lugom. Ta preskusna metoda prinaša izlužke, ki so lahko nadalje določeni s fizičnimi, kemičnimi in z ekotoksiološkimi metodami v skladu z obstoječimi standardnimi metodami. Rezultati analize izlužka so predstavljeni kot funkcija razmerja tekoče/trdno. Preskus ni primeren za vrste, ki so hlapne pod okoljskimi pogoji. Uporaba zgolj te preskusne metode ni zadostna za določevanje odziva materialov na izluževanje pod določenimi pogoji, ki se razlikujejo od pogojev iz preskusnega postopka, saj ta običajno zahteva uporabo več preskusnih metod, modeliranje odziva in validacijo modela. Ta del ISO/TS 21268 ne naslavlja vprašanj glede zdravja in varnosti. Kot je navedeno v Klavzuli 4, zgolj določa lastnosti izluženega.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 21268-3 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 7, Soil
and site assessment.
ISO/TS 21268 consists of the following parts, under the general title Soil quality — Leaching procedures for
subsequent chemical and ecotoxicological testing of soil and soil materials:
⎯ Part 1: Batch test using a liquid to solid ratio of 2 l/kg dry matter
⎯ Part 2: Batch test using a liquid to solid ratio of 10 l/kg dry matter
⎯ Part 3: Up-flow percolation test
⎯ Part 4: Influence of pH on leaching with initial acid/base addition
