Application Summary AI generated

This standard specifies a laboratory test method for determining the inherent biodegradability of chemical substances under aerobic conditions, using a modified MITI (Ministry of International Trade and Industry) procedure. It is applied in environmental risk assessment and regulatory compliance for industrial chemicals, particularly to evaluate whether a substance can undergo significant biodegradation in wastewater treatment plants or natural aquatic environments. The test is relevant for chemical manufacturers, environmental agencies, and product safety evaluators in China.
