Also numbered BS 6068:Part 5:Sec 5.11 (1993) and ISO 9408. 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: are insoluble in the test conditions; do not react and react with CO2 absorbent; are volatile, provided that a suitable respirometer is used; are soluble 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. Also includes detailed annexes.
