EN ISO 14855-1:2012

Determination of the ultimate aerobic biodegradability of plastic materials under controlled composting conditions - Method by analysis of evolved carbon dioxide - Part 1: General method (ISO 14855-1:2012)

ISO 14855-1:2012 specifies a method for the determination of the ultimate aerobic biodegradability of plastics, based on organic compounds, under controlled composting conditions by measurement of the amount of carbon dioxide evolved and the degree of disintegration of the plastic at the end of the test. This method is designed to simulate typical aerobic composting conditions for the organic fraction of solid mixed municipal waste. The test material is exposed to an inoculum which is derived from compost. The composting takes place in an environment wherein temperature, aeration and humidity are closely monitored and controlled. The test method is designed to yield the percentage conversion of the carbon in the test material to evolved carbon dioxide as well as the rate of conversion.
Also specified is a variant of the method, using a mineral bed (vermiculite) inoculated with thermophilic microorganisms obtained from compost with a specific activation phase, instead of mature compost. This variant is designed to yield the percentage of carbon in the test substance converted to carbon dioxide and the rate of conversion.

Bestimmung der vollständigen aeroben Bioabbaubarkeit von Kunststoff-Materialien unter den Bedingungen kontrollierter Kompostierung - Verfahren mittels Analyse des freigesetzten Kohlenstoffdioxides - Teil 1: Allgemeines Verfahren (ISO 14855-1:2012)

Dieser Teil der ISO 14855 legt ein Verfahren fest, mit dem unter geregelten Kompostierbedingungen durch Messung der Menge des gebildeten Kohlendioxids und des Grades des Zerfalls des Kunststoffs am Ende der Prüfung die vollständige aerobe Bioabbaubarkeit von Kunststoffen, die auf organischen Verbindungen beruhen, bestimmt wird. Dieses Verfahren ist dafür ausgelegt, typische aerobe Kompostierbedingungen für den organischen Anteil in festem gemischtem städtischem Abfall zu simulieren. Die Prüfsubstanz wird einem Inokulum ausgesetzt, das aus Kompost gewonnen wird. Die Kompostierung erfolgt in einer Umgebung, in der Temperatur, Begasung und Feuchte genau überwacht und geregelt werden. Das Prüfverfahren dient der Feststellung der prozentualen Umwandlung des Kohlenstoffs in der Prüfsubstanz in freigesetztes Kohlendioxid sowie der Geschwindigkeit dieser Umwandlung.
Die Unterabschnitte 8.6 und 8.7 legen eine Variante des Verfahrens fest, bei der anstelle des ausgereiften Kompostes ein mineralisches Festbett (Vermiculit) mit thermophilen Mikroorganismen, die aus dem Kompost innerhalb einer spezifischen Aktivierungsphase gewonnen werden, beimpft wird. Diese Variante wurde entwickelt, um den prozentualen Anteil des in Kohlendioxid umgewandelten Kohlenstoffs in der Prüfsubstanz und die Geschwindigkeit dieser Umwandlung festzustellen.
Die in diesem Teil der ISO 14855 beschriebenen Bedingungen entsprechen möglicherweise nicht immer den optimalen Bedingungen, unter denen der maximale Grad an Bioabbau erreicht wird.

Določanje končne aerobne biorazgradljivosti in razkroja polimernih materialov pod nadzorovanimi pogoji kompostiranja - Metoda z analizo sproščenega ogljikovega dioksida - 1. del: Splošna metoda (ISO 14855-1:2012)

Ta del standarda ISO 14855 določa metodo za določanje končne aerobne biorazgradljivosti in razkroja polimernih materialov, ki temeljijo na organskih sestavinah, pod nadzorovanimi pogoji kompostiranja z merjenjem količine sproščenega ogljikovega dioksida in stopnje razkroja polimernih materialov na koncu preskusa. Ta metoda je izdelana za simulacijo značilnih aerobnih pogojev kompostiranja organskega deleža trdnih mešanih komunalnih odpadkov. Preskusni material je izpostavljen inokulumu, ki izhaja iz komposta. Kompostiranje poteka v okolju, kjer so temperatura, zračnost in vlaga natančno spremljane in nadzorovane. Preskusna metoda je izdelana tako, da proizvede odstotek pretvorbe ogljika iz preskusnega materiala v sproščeni ogljikov dioksid ter tudi stopnjo pretvorbe. V točkah 8.6 in 8.7 je navedena različica metode, ki uporablja vermikulit z vcepljenimi termofilnimi mikroorganizmi, ki se namesto iz zrelega komposta pridobijo iz komposta z določeno fazo aktiviranja. Ta metoda je izdelana tako, da proizvede odstotek ogljika v preskusni snovi, ki se pretvori v ogljikov dioksid, in stopnjo pretvorbe. Pogoji, ki so opisani v tem delu standarda ISO 14855 niso vedno enaki idealnim pogojem, kjer pride do največje stopnje biorazgradljivosti.
