Sets out a method for the evaluation of the 'inherent' biodegradability of organic compounds. Determination of the percentage removal of dissolved organic carbon (DOC) or chemical oxygen demand (COD) at regular intervals allow evaluation of the 'inherent' biodegradability of the test compound. The method generally applies to compounds which are soluble in the test medium, non-volatile, not lost by foaming of the test medium and not inhibitory to the test microorganisms at the concentration chosen for the test. Technically equivalent to ISO 9888:1991.
