Proposes the adoption of ISO 9888:1991 as a Joint Australian/New Zealand Standard. This proposed Standard specifies a method for the determination of the 'inherent' biodegradability of an organic compound at a given concentration by aerobic microorganisms. Determination of the percentage removal of dissolved organic carbon or chemical oxygen demand allows evaluation of the biodegradability of the compound. Copies of ISO 9888:1991 may be purchased from or viewed at any Standards Australia office.
