DS/EN 29439:1993 Water quality. Evaluation in an aqueous medium of the "ultimate" aerobic biodegradability of organic compounds. Method by analysis of released carbon dioxide
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).
