Annotation of standard text ÖNORM EN ISO 23977-2 :

Dieses Dokument legt ein Laborprüfverfahren für die Bestimmung des Grads und der Geschwindigkeit des aeroben Bioabbaus von Kunststoffmaterialien fest. Der Bioabbau von Kunststoffmaterialien wird durch die Messung des Sauerstoffbedarfs in einem geschlossenen Respirometer bei Kontakt mit Meerwasser aus Küstenbereichen unter Laborbedingungen bestimmt. Die in diesem Dokument beschriebenen Bedingungen entsprechen möglicherweise nicht immer den optimalen Bedingungen für den maximalen Grad des Bioabbaus, jedoch ist dieses Prüfverfahren dafür ausgelegt, einen Hinweis auf die potentielle Bioabbaubarkeit von Kunststoffmaterialien zu liefern.
