This standard specifies a procedure for determining the degree of aerobic degradation of fully formulated lubricants. The organic material in a fully formulated lubricant is exposed in a synthetic aqueous medium under laboratory conditions to an inoculum from activated sludge. Biodegradation resulting in mineralisation of the organic material is determined by measuring the oxygen consumption in a closed respirometer. The above mentioned method applies to fully formulated lubricants which a) are water-soluble, non-water soluble or emulsifiable b) are not toxic and not inhibitory to the test microorganisms at the test concentration. The presence of inhibitory effects can be determined as specified in this European standard.
