This International Standard specifies a method, by analysis of released carbon dioxide, for the evalu-ation in an aqueous medium of the "ultimate" biodegradability of organic compounds at a given concentration by aerobic micro-organisms. The method applies to organic compounds which are a) soluble in the test conditions; b) insoluble in the test conditions, in which case special measures may be necessary to achieve good dispersion of the compound; c) non-volatile or which have a negligible vapour pressure under the conditions of the test; d) not inhibitory to the test micro-organisms at the concentration chosen for the test. The presence of an inhibitory effect can be determined as specified in 8 3 , or by using any other method for determining the inhibitory effect of a compound on bacteria (see, for example, ISO 8192).
