Also numbered BS EN 29439 & BS ISO 9439 Specifies a method, by analysis of released carbon dioxide, for the evaluation in an aqueous medium of the "ultimate" biodegradability of organic compounds at a given concentration by aerobic micro-organisms. Applies to organic compounds which are: insoluble in the test conditions; non-volatile or which have a negligible vapour pressure under the conditions of the test; soluble in the test conditions; not inhibitory to the test micro-organisms at the concentration chosen for the test. Coverage includes definitions, reagents, procedure and apparatus. Also includes detailed annexes.
