Plastics - Determination of the ultimate aerobic biodegradability of plastic materials in soil by measuring the oxygen demand in a respirometer or the amount of carbon dioxide evolved (ISO 17556:2019)

This document specifies a method for determining the ultimate aerobic biodegradability of plastic materials in soil by measuring the oxygen demand in a closed respirometer or the amount of carbon dioxide evolved. The method is designed to yield an optimum degree of biodegradation by adjusting the humidity of the test soil.
If a non-adapted soil is used as an inoculum, the test simulates the biodegradation processes which take place in a natural environment; if a pre-exposed soil is used, the method can be used to investigate the potential biodegradability of a test material.
This method applies to the following materials:
—          natural and/or synthetic polymers, copolymers or mixtures of these;
—          plastic materials which contain additives such as plasticizers or colorants;
—          water-soluble polymers.
It does not necessarily apply to materials which, under the test conditions, inhibit the activity of the microorganisms present in the soil. Inhibitory effects can be measured using an inhibition control or by another suitable method. If the test material inhibits the microorganisms in the soil, a lower test material concentration, another type of soil or a pre-exposed soil can be used.

Kunststoffe - Bestimmung der vollständigen aeroben Bioabbaubarkeit von Kunststoffmaterialien im Boden durch Messung des Sauerstoffbedarfs in einem Respirometer oder der Menge des entstandenen Kohlendioxids (ISO 17556:2019)

Dieses Dokument legt ein Verfahren zum Bestimmen der vollständigen aeroben biologischen Abbaubarkeit von Kunststoffmaterialien im Boden durch Messen des Sauerstoffbedarfs in einem geschlossenen Respiro-meter oder durch Messen der Menge des entwickelten Kohlendioxids fest. Das Verfahren ist entwickelt worden, um einen bestmöglichen Grad des biologischen Abbaus durch Einstellen der Feuchtigkeit des Prüfbodens zu erhalten.
Wenn ein nicht angepasster Boden als Inokulum verwendet wird, simuliert die Prüfung den biologischen Abbauprozess, der in einer natürlichen Umgebung abläuft; wird ein vorexponierter Boden verwendet, kann das Verfahren zum Untersuchen der potenziellen biologischen Abbaubarkeit eines Prüfmaterials ange¬wendet werden.
Dieses Verfahren gilt für folgende Materialien:
—   natürliche und/oder künstliche Polymere, Copolymere oder deren Gemische;
—   Kunststoffmaterialien, die Zusatzstoffe wie Weichmacher oder Farbmittel enthalten;
—   wasserlösliche Polymere.
Dieses Verfahren gilt nicht notwendigerweise für Materialien, die unter Prüfbedingungen die Aktivität der im Boden vorhandenen Mikroorganismen beeinträchtigen. Inhibierungseffekte können durch Anwendung eines Inhibierungskontrollversuchs oder durch ein anderes geeignetes Verfahren gemessen werden. Wenn das Prüfmaterial die Mikroorganismen im Boden hemmt, kann eine geringere Konzentration des Prüfmate-rials, ein anderer Bodentyp oder ein vorexponierter Boden eingesetzt werden.

Plastiques - Détermination de la biodégradabilité aérobie ultime des matériaux plastiques dans le sol par mesure de la demande en oxygène dans un respiromètre ou de la teneur en dioxyde de carbone libéré (ISO 17556:2019)

Le présent document spécifie une méthode de détermination de la biodégradabilité aérobie ultime des matériaux plastiques dans le sol en mesurant la demande en oxygène dans un respiromètre fermé ou la quantité de dioxyde de carbone libéré. La méthode est conçue pour produire un taux de biodégradation optimal en ajustant l'humidité du sol d'essai.
Si un sol non modifié est utilisé comme inoculum, l'essai simule les processus de biodégradation qui ont lieu dans un environnement naturel; si un sol pré-exposé est utilisé, la méthode peut être utilisée pour étudier la biodégradabilité potentielle d'un matériau d'essai.
Cette méthode est applicable aux matériaux suivants:
—          polymères, copolymères naturels et/ou synthétiques ou leurs mélanges;
—          matériaux plastiques contenant des additifs tels que plastifiants ou colorants;
—          polymères solubles dans l'eau.
Elle ne s'applique pas nécessairement aux matériaux qui, dans les conditions de l'essai, ont un effet inhibiteur vis-à-vis de l'activité des micro-organismes présents dans le sol. Les effets inhibiteurs peuvent être déterminés au moyen d'un contrôle de l'inhibition ou par une autre méthode appropriée. Si le matériau d'essai a un effet inhibiteur vis-à-vis des micro-organismes présents dans le sol, il est possible d'utiliser une concentration de matériau d'essai plus faible, un autre type de sol ou un sol pré-exposé.

Polimerni materiali - Ugotavljanje končne aerobne biorazgradljivosti polimernih materialov v zemlji z merjenjem porabe kisika v respirometru ali količine nastalega ogljikovega dioksida (ISO 17556:2019)

Ta dokument opisuje metodo za ugotavljanje končne aerobne biorazgradljivosti polimernih materialov v zemlji z merjenjem porabe kisika v zaprtem respirometru ali količine nastalega ogljikovega dioksida. Namen metode je doseči čim večjo stopnjo biorazgradljivosti s prilagoditvijo vlažnosti preskusne zemlje.
Če se kot inokulum uporabi neprilagojena zemlja, preskus simulira postopke biorazgraditve, ki potekajo v naravnem okolju; če se uporabi predhodno izpostavljena zemlja, se lahko metoda uporabi za preiskavo potencialne biorazgradljivosti preskusnega materiala.
Ta metoda zadeva naslednje materiale:
– naravne in/ali sintetične polimere, kopolimere ali njihove mešanice;
– polimerne materiale, ki vsebujejo dodatke, kot so mehčala ali barvila;
– polimere, topne v vodi.
Ne nanaša se nujno na materiale, ki pod preskusnimi pogoji zavirajo delovanje mikroorganizmov, prisotnih v zemlji. Zaviralne učinke je mogoče meriti na podlagi nadzora zaviranja ali z drugo ustrezno metodo. Če preskusni material zavira delovanje mikroorganizmov v zemlji, se lahko uporabi manjša koncentracija preskusnega materiala, druga vrsta zemlje ali predhodno izpostavljena zemlja.
