Resumen:
This European 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 can be determined by measuring released CO2 in a total organic carbon (TOC-) analyser.
