ISO 9408 is an International Standard that 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 wastewaters at a given concentration by aerobic microorganisms. The method applies to organic compounds which: Are water soluble under the
