Scope
This standard specifies the test method for measuring the biochemical oxygen demand in chemical biodegradation screening tests.
This standard is applicable to water-soluble solid or liquid organic substances, and can also be used for volatile and low-water-soluble organic substances.
This standard is applicable to organic substances that have no inhibitory effect on bacteria at the test concentration.
This standard provides a method for screening the biodegradation capacity of the test substance.
