Sets out a method for the evaluation of the 'ready' biodegradability of organic compounds by aerobic microorganisms using a test medium. Determination of the biochemical oxygen demand at regular intervals allows evaluation of the biodegradability of the test compound. The method generally applies to compounds which are soluble in the test medium. Technically equivalent to ISO 10707:1994.

This Standard specifies a method for the evaluation of the 'ready' biodegradability of organic compounds at a given concentration by aerobic microorganisms.The conditions described in this Standard do not necessarily always correspond to the optimal conditions allowing the maximum value of biodegradation to occur.The method applies to all organic compounds which are sufficiently water soluble to prepare a stock solution or poorly water soluble using special dosing techniques.WARNING AND SAFETY PRECAUTIONS: ACTIVATED SLUDGE AND SEWAGE MAY CONTAIN POTENTIALLY PATHOGENIC ORGANISMS. THEREFORE APPROPRIATE PRECAUTIONS SHOULD BE TAKEN WHEN HANDLING THEM. TOXIC TEST COMPOUNDS AND THOSE WITH UNKNOWN PROPERTIES SHOULD BE HANDLED WITH CARE.
