Also numbered BS EN 29408 Specifies a method, by determination of the oxygen demand in a closed respirometer, 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: do not reach and react with the CO2 absorbent; are soluble in the test conditions; are volatile provided that a suitable respirometer is used; are insoluble in the test conditions; are not inhibitory to the test micro-organisms at the concentration chosen for the test. Coverage includes definitions, reagents, procedure and apparatus. Includes detailed annexes.
