Determination of the ultimate aerobic biodegradability of plastic materials under controlled composting conditions - Method by analysis of evolved carbon dioxide - Part 2: Gravimetric measurement of carbon dioxide evolved in a laboratory-scale test (ISO 14855-2:2018)

This document specifies a method for determining the ultimate aerobic biodegradability of plastic materials under controlled composting conditions by gravimetric measurement of the amount of carbon dioxide evolved. The method is designed to yield an optimum rate of biodegradation by adjusting the humidity, aeration and temperature of the composting vessel.
The method applies to the following materials:
—          natural and/or synthetic polymers and copolymers, and mixtures of these;
—          plastic materials that contain additives such as plasticizers or colorants;
—          water-soluble polymers;
—          materials that, under the test conditions, do not inhibit the activity of microorganisms present in the inoculum.
If the test material inhibits microorganisms in the inoculum, another type of mature compost or pre-exposure compost can be used.

Bestimmung der vollständigen aeroben Bioabbaubarkeit von Kunststoff-Materialien unter den Bedingungen kontrollierter Kompostierung - Verfahren mittels Analyse des freigesetzten Kohlenstoffdioxides - Teil 2: Gravimetrische Messung des freigesetzten Kohlenstoffdioxides im Labormaßstab (ISO 14855-2:2018)

Dieses Dokument legt ein Verfahren zur Bestimmung der vollständigen aeroben Bioabbaubarkeit von Kunststoff-Materialien unter den Bedingungen kontrollierter Kompostierung durch gravimetrische Messung der Menge des freigesetzten Kohlenstoffdioxids fest. Das Verfahren ist dafür ausgelegt, eine optimale Geschwindigkeit des Bioabbaus durch Anpassung von Feuchte, Begasung und Temperatur des Kompostiergefäßes zu erreichen.
Das Verfahren ist auf folgende Substanzen anwendbar:
—   natürliche und/oder synthetische Polymere und Copolymere sowie Gemische aus diesen;
—   Kunststoffe, die Additive, wie z. B. Weichmacher oder Farbstoffe, enthalten;
—   wasserlösliche Polymere;
—   Substanzen, die unter Prüfbedingungen die Aktivität der im Inokulum vorhandenen Mikroorganismen nicht inhibieren.
Wirkt die Prüfsubstanz inhibierend auf die Mikroorganismen im Inokulum, kann eine andere Art von ausge¬reiftem Kompost oder voradaptierter Kompost verwendet werden.

Détermination de la biodégradabilité aérobie ultime des matériaux plastiques dans des conditions contrôlées de compostage - Méthode par analyse du dioxyde de carbone libéré - Partie 2: Mesurage gravimétrique du dioxyde de carbone libéré lors d'un essai de laboratoire (ISO 14855-2:2018)

Le présent document spécifie une méthode de détermination de la biodégradabilité aérobie ultime des matériaux plastiques, dans des conditions de compostage contrôlées, par mesurage gravimétrique de la teneur en dioxyde de carbone libéré. Cette méthode est conçue pour produire un taux de biodégradation optimal en ajustant l'humidité, l'aération et la température du récipient de compostage.
La méthode s'applique aux matériaux suivants:
—          polymères et copolymères naturels et/ou synthétiques, et mélanges des deux;
—          matériaux plastiques contenant des additifs tels que plastifiants ou colorants;
—          polymères solubles dans l'eau;
—          matériaux qui, dans les conditions d'essai, n'inhibent pas l'activité des micro-organismes présents dans l'inoculum.
Si le matériau d'essai inhibe les micro-organismes dans l'inoculum, il est possible d'utiliser un autre type de compost mature ou un compost de pré-exposition.

Določanje končne aerobne biorazgradljivosti in razkroja polimernih materialov pod nadzorovanimi pogoji kompostiranja - Metoda z analizo sproščenega ogljikovega dioksida - 2. del: Gravimetrične metode za določevanje sproščenega ogljikovega dioksida v laboratorijskem merilu (ISO 14855-2:2018)

Ta dokument opisuje metodo za ugotavljanje končne aerobne biorazgradljivosti polimernih materialov pod nadzorovanimi pogoji kompostiranja z gravimetričnim merjenjem količine nastalega ogljikovega dioksida. Namen metode je doseči čim večjo stopnjo biorazgradljivosti s prilagoditvijo vlažnosti, zračenja in temperature posode za kompostiranje.
Ta metoda se uporablja za naslednje materiale:
– naravni in/ali sintetični polimeri in kopolimeri ter njihove mešanice;
– polimerni materiali, ki vsebujejo dodatke, kot so mehčala ali barvila;
– polimeri, topni v vodi;
– materiali, ki v preskusnih pogojih ne zavirajo delovanja mikroorganizmov, prisotnih v
inokulumu.
Če preskusni material zavira mikroorganizme v inokulumu, se lahko uporabi druga vrsta zrelega komposta ali vnaprej izpostavljenega komposta.

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).
