Plastiques — Détermination de la biodégradation aérobie des matériaux plastiques exposés à l'eau de mer — Partie 2: Méthode par mesure de la demande en oxygène dans un respiromètre fermé

Abstract / scope

This document specifies a laboratory test method for determining the degree and rate of the aerobic biodegradation level of plastic materials. Biodegradation of plastic materials is determined by measuring the oxygen demand in a closed respirometer when exposed to seawater sampled from coastal areas under laboratory conditions.

The conditions described in this document might not always correspond to the optimum conditions for the maximum degree of biodegradation, however this test method is designed to give an indication of the potential biodegradability of plastic materials.

NOTE This document addresses plastic materials but can also be used for other materials.
