Water quality. Evaluation of ultimate aerobic biodegradability of organic compounds in aqueous medium by determination of oxygen demand in a closed respirometer not-for-sale and to chip carrier circuits1 Scope This International Standard specifies a method, by determination of the oxygen demand in a closed respirometer, for the evaluation in aqueous medium of the ultimate biodegradability of organic compounds and waste waters at a given concentration by aerobic microorganisms. The method applies to organic compounds which a) are water soluble under the conditions of the test; b) are poorly water soluble under the conditions of the test, in which
