Application Summary AI generated

This standard specifies a pilot-scale test method for measuring how much a plastic material physically breaks down (disintegrates) into small fragments when exposed to controlled composting conditions. It is applied in the plastics industry and waste management sector to evaluate the compostability of biodegradable plastics, particularly for products like compostable bags or packaging intended for industrial composting facilities. The test provides data on physical disintegration, distinct from biodegradation, to assess material behavior under realistic, larger-scale composting environments.
