Scope
This document describes the test principles of the simulation test for the biodegradability of chemical substances discharged into wastewater in chemical evaluation, the applicability and limitations of five test methods, the information of the test objects, reference substances, quality assurance and quality control, data and reports.
This document is applicable to water-soluble or weakly water-soluble and non-volatile test objects, and can also be used for the determination of volatile test objects.
This series of documents is not applicable to the determination of nitrogen and phosphorus removal in sewage.
