Abstract
What is ISO 9439 - Evaluation of ultimate aerobic biodegradability of organic compounds about?
ISO 9439 specifies a method, by determination of carbon dioxide (CO2), for the evaluation in an aqueous medium of the ultimate biodegradability of organic compounds at a given concentration by aerobic microorganisms. ISO 9439 applies to organic compounds which are:
water-soluble under the conditions of the test, in which case removal of DOC may be determined as additional information (see annex D)
