Plastics - Determination of the aerobic biodegradation of non-floating materials exposed to marine sediment - Method by analysis of evolved carbon dioxide (ISO 22404:2019)
This document specifies a laboratory test method to determine the degree and rate of aerobic biodegradation level of plastic materials. This test method can also be applied to other materials.
Biodegradation is determined by measuring the CO2 evolved by the plastic material when exposed to marine sediments sampled from a sandy tidal zone and kept wet with salt-water under laboratory conditions.
This test method is a simulation under laboratory conditions of the habitat found in sandy tidal zone that, in marine science, is called eulittoral zone.
The conditions described in this document might not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.
Deviations from the test conditions described in this document are justified in the test report.
Kunststoffe - Bestimmung des aeroben Bioabbaus von nicht-schwimmenden Materialien, die marinem Sediment ausgesetzt sind - Verfahren mittels Analyse des freigesetzten Kohlenstoffdioxids (ISO 22404:2019)
Dieses Dokument legt ein Laborprüfverfahren für die Bestimmung des Grads und der Geschindigkeit des aeroben Bioabbaus von Kunststoffmaterialien fest. Dieses Prüfverfahren kann darüber hinaus auch auf andere Materialien angewendet werden.
Bioabbau wird durch die Messung des durch das Kunststoffmaterial erzeugten CO2 bestimmt, wenn das Material Meeressediment ausgesetzt war, das einer sandigen Gezeitenzone entnommen und mit Salzwasser unter Laborbedingungen aufbewahrt wurde.
Dieses Prüfverfahren ist eine Simulation unter Laborbedingungen des in der sandigen Gezeitenzone ange¬troffenen Habitats, das in der Meereswissenschaft als eulitorale Zone bezeichnet wird.
Die in diesem Dokument beschriebenen Bedingungen entsprechen möglicherweise nicht immer den Optimal¬bedingungen, unter denen der höchste Grad an biologischem Abbau möglich ist.
Abweichungen von den in diesem Dokument beschriebenen Prüfbedingungen werden in dem Prüfbericht begründet.
Plastiques - Détermination de la biodégradation aérobie des matériaux non flottants exposés aux sédiments marins - Méthode par analyse du dioxyde de carbone libéré (ISO 22404:2019)
Le présent document spécifie une méthode d’essai en laboratoire permettant de déterminer le taux et le niveau de biodégradation aérobie des matériaux plastiques. Cette méthode d’essai peut également être appliquée à d’autres matériaux.
La biodégradation est déterminée en mesurant le CO2 libéré par le matériau plastique lorsqu’il est exposé à des sédiments marins prélevés dans une zone tidale sableuse et maintenus humides dans de l’eau salée, dans des conditions de laboratoire.
Cette méthode d’essai est une simulation, dans des conditions de laboratoire, de l’habitat présent dans la zone tidale sableuse, connue sous le nom de «zone eulittorale» en sciences marines.
Les conditions décrites dans le présent document ne correspondent pas nécessairement aux conditions optimales permettant d’obtenir le taux maximal de biodégradation.
Les écarts par rapport aux conditions d’essai décrites dans le présent document sont justifiés dans le rapport d’essai.
Polimerni materiali - Določanje aerobne biorazgradljivosti neplavajočih materialov, izpostavljenih morskim sedimentom - Metoda z analizo sproščenega ogljikovega dioksida (ISO 22404:2019)
Ta dokument določa laboratorijsko preskusno metodo za določevanje stopnje in hitrosti aerobne biorazgradnje polimernih materialov. To preskusno metodo je mogoče uporabiti tudi za druge materiale.
Biorazgradljivost se določi z merjenjem CO2, ki se sprošča iz polimernega materiala ob izpostavljenosti morskim sedimentom, vzorčenim iz peščenega območja plimovanja in vlaženim s slano vodo pod laboratorijskimi pogoji.
Ta preskusna metoda je simulacija habitata v peščenem območju plimovanja, ki se v morski znanosti imenuje eulitoralno območje, pod laboratorijskimi pogoji.
Pogoji, ki so opisani v tem dokumentu, morda niso vedno enaki idealnim pogojem, pri katerih pride do največje stopnje biorazgradnje.
Odstopanja od preskusnih pogojev, opisanih v tem dokumentu, so utemeljena v poročilu o preskusu.
