Plastics. Methods for the preparation of samples for biodegradation testing of plastic materials Ingestion-build-81500 This latest revision reflects recent1 Scope This International Standard describes methods for the preparation of test samples used in the determination of the ultimate aerobic and anaerobic biodegradability of plastic materials in an aqueous medium, soil, controlled compost or anaerobic digesting sludge. The methods described are designed to provide dimensional consistency of test samples, resulting in improved reproducibility of test results during the determination of the ultimate
