FTM 3013 (FED-STD-791C method 3013) Determination of Particulate Contamination in Synthetic Turbine Engine Lubricants
Turbine engines rely on lubricating oils to dissipate heat and safeguard moving parts. To avoid damage to sensitive system components, the lubricating fluids must be clean, without significant levels of particulate matter. This test gravimetrically determines the amount of particulate matter in synthetic turbine oils.
The oil is filtered through a membrane filter which is then solvent rinsed, dried and reweighed. Reported is the mg of particulate matter per liter of oil.
