|OELCHECK test instrument:||Millipore filter system, scale, desiccator|
|Sample quantity:||10 ml|
|Test result:||solid contaminants|
|Analysis for:|| |
Gear, motor and hydraulic oils, insulating oils, circulation oils
|Brief description:|| |
The oil sample is diluted with solvent and drawn through a filter with a pore width of 0.8 µm. The difference in filter weight resulting from the "solid contaminants" is converted into mg/kg by weight.
The quantity of "solid contaminants" provides information on the overall pollution of the oil for investigation. The particles on the filter paper can be investigated further using a microscope.
Sometimes conclusions can subsequently be drawn on the origin of these residues.
|Underlying test standard:||OELCHECK test method OPM 080|
