Application Summary AI generated

This standard specifies laboratory test methods for measuring the degradation rate and disintegration degree of plastic materials when exposed to marine environmental matrices, such as seawater and sediment. It is applied in the plastics industry for evaluating the environmental fate of plastic products, particularly for materials marketed as biodegradable in marine environments. The testing context supports research, quality control, and regulatory assessments of plastic pollution and marine biodegradability claims.
