Lubricants. Determination of aerobic biological degradation of fully formulated lubricants in an aqueous solution. Test method based on CO2-productionWhat is this standard about? This document 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)
