Application Summary AI generated

This standard specifies a test method for measuring the aerobic biodegradation of non-floating plastic materials under conditions simulating the seawater/sediment interface. It is applied in marine environmental testing to evaluate the ultimate biodegradability of plastics that sink to the seafloor, such as fishing gear or packaging debris, by analyzing the carbon dioxide they release. The method is relevant for research, product development, and regulatory assessment of plastic materials intended for use in marine environments.
