Application Summary AI generated

This standard specifies a laboratory test method for determining the ultimate aerobic biodegradability of plastic materials by measuring the carbon dioxide they release under controlled composting conditions. It is applied in the plastics industry to evaluate whether products like packaging, bags, or disposable items are capable of biodegrading in industrial composting facilities. The method is used for quality control, certification, and regulatory compliance to confirm that materials meet compostability claims.
