Application Summary AI generated
This standard specifies a laboratory test method to determine the ready biodegradability of organic chemicals by measuring the dissolved organic carbon (DOC) removed from an aqueous solution over 28 days. It is applied in environmental risk assessment and regulatory compliance for industrial chemicals, detergents, and pharmaceuticals to evaluate their potential for rapid degradation in aerobic aquatic environments. The test is used by chemical manufacturers, environmental agencies, and testing laboratories to classify substances for hazard labeling and wastewater treatment planning.
