Specifies a method, by analysis of biochemical oxygen demand, for the evaluation in an aqueous medium of the "ultimate" biodegradability of organic compounds. Applies to all organic compounds that are sufficiently water soluble to prepare a stock solution or poorly water soluble when using special dosing techniques. Coverage includes: reagents, apparatus and procedure. Also gives detailed definitions and annexes. BS AMD 9903 RENUMBERS STANDARD
