|OELCHECK test instrument: ||Millipore filter system, scale, desiccator |
|Sample quantity:||10 ml |
|Unit: ||mg/kg (weight) |
|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.
|Statement: || |
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 |
