Plastics - Determination of the degree of disintegration of plastic materials in marine habitats under real field conditions (ISO 22766:2020)

This document specifies test methods for the determination of the degree of disintegration of plastic materials exposed to marine habitats under real field conditions.
The marine areas under investigation are the sandy sublittoral and the sandy eulittoral zone where plastic materials can either be placed intentionally (e.g. biodegradable fishing nets) or end up as litter due to irresponsible human behaviour. This depends on their physical characteristics, form and size of the materials, and on water currents and tidal movements.
This document specifies the general requirements of the apparatus, and the procedures for using the test methods described.
The determination of the level of disintegration of plastic materials exposed to pelagic zones such as the sea surface or the water column above the seafloor are not within the scope of this document.
This document is not suitable for the assessment of disintegration caused by heat or light exposure.
The described field test is a disintegration test and not a biodegradation test. Therefore, it cannot be used for demonstrating biodegradation or for making unqualified claims such as "biodegradable in marine environment" and similar.

Kunststoffe - Bestimmung des Zersetzungsgrades von Kunststoff-Materialien in marinen Lebensräumen unter realen Feldbedingungen (ISO 22766:2020)

Dieses Dokument legt Prüfverfahren für die Bestimmung des Grads der Zersetzung von Kunststoffmaterialien, die Meereshabitaten ausgesetzt sind, unter realen Feldbedingungen fest.
Die untersuchten Meeresbereiche umfassen die sandige sublitorale und sandige eulitorale Zone, wo Kunststoffmaterialien entweder absichtlich (z. B. biologisch abbaubare Fischernetze) platziert werden oder als Abfall aufgrund von verantwortungslosem menschlichem Verhalten enden können. Dies hängt von ihren physikalischen Eigenschaften, der Form und Größe der Materialien sowie von Wasserströmungen und Gezeitenbewegungen ab.
Dieses Dokument legt allgemeine Anforderungen an die Prüfeinrichtung und die Verfahrensanweisungen zur Verwendung der beschriebenen Prüfverfahren fest.
Die Bestimmung des Zersetzungsgrads von Kunststoffmaterialien, die Pelagialzonen wie etwa der Meeresoberfläche oder der Wassersäule über dem Meeresboden ausgesetzt sind, ist nicht vom Anwendungsbereich dieses Dokuments umfasst.
Dieses Dokument ist nicht für die Beurteilung von Zersetzung durch Wärme- oder Lichtexposition geeignet.
Die beschriebene Feldprüfung ist eine Zersetzungsprüfung und keine Bioabbauprüfung. Sie kann daher nicht für den Nachweis des Bioabbaus oder unqualifizierte Aussagen wie „bioabbaubar in Meeresumgebung“ oder Ähnliches verwendet werden.

Plastiques - Détermination du degré de désintégration des matériaux plastiques dans les habitats marins en conditions réelles (ISO 22766:2020)

Le présent document spécifie des méthodes d’essai pour la détermination du degré de désintégration des matériaux plastiques exposés à des habitats marins en conditions réelles.
Les zones marines étudiées sont la zone sublittorale sableuse et la zone eulittorale sableuse, dans lesquelles des matériaux plastiques peuvent soit être placés intentionnellement (par exemple filets de pêche biodégradables), soit se retrouver sous forme de déchets en raison d’un comportement humain irresponsable. Cela dépend de leurs caractéristiques physiques, de leur forme et de leur taille, et des courants et mouvements de marées.
Le présent document spécifie les exigences générales relatives à l’appareillage et les modes opératoires permettant d’utiliser les méthodes d’essai décrites.
La détermination du niveau de désintégration des matériaux plastiques exposés à des zones pélagiques, telles que la surface de la mer ou la colonne d’eau au-dessus du fond océanique, n’entre pas dans le domaine d’application du présent document.
Le présent document ne convient pas pour évaluer la désintégration causée par une exposition à la chaleur ou à la lumière.
L’essai sur le terrain décrit est un essai de désintégration et non un essai de biodégradation. Par conséquent, il ne peut pas être utilisé pour démontrer la biodégradation ou pour émettre des affirmations générales de type «biodégradable en milieu marin» ou autres assertions similaires.

Polimerni materiali - Ugotavljanje stopnje razpada polimernih materialov v morskih habitatih v realnih terenskih pogojih (ISO 22766:2020)

Ta dokument določa preskusne metode za ugotavljanje stopnje razpada polimernih materialov, izpostavljenih morskim habitatom v realnih terenskih pogojih.
Morska območja, ki se preiskujejo, so peščena sublitoralna in peščena eulitoralna območja, kjer se lahko polimerni materiali odlagajo namerno (npr. biorazgradljive ribiške mreže) ali zaradi neodgovornega človekovega vedenja tam končajo kot smeti. To je odvisno od njihovih fizičnih lastnosti, oblike in velikosti materialov ter vodnih tokov in plimovanja.
Ta dokument določa splošne zahteve naprave in postopke za uporabo opisanih preskusnih metod.
Ugotavljanje stopnje razpada polimernih materialov, izpostavljenih pelagičnim območjem, kot je morska gladina ali vodni steber nad morskim dnom, ne spada na področje uporabe tega dokumenta.
Ta dokument ni primeren za ocenjevanje razpada zaradi izpostavljenosti toploti ali svetlobi.
Opisani terenski preskus je preskus razpadanja in ne preskus biorazgradljivosti, zato ga ni mogoče uporabiti za dokazovanje biorazgradljivosti ali podajanje neustreznih trditev, kot je »biorazgradljivo v morskem okolju«, in podobno.
