|OELCHECK test instrument: ||Millipore filter system, scale, desiccator |
|Sample quantity:||20 ml |
|Unit: ||% (weight) |
|Test result: ||solid contaminants |
|Analysis for: ||hydraulic and gear oils experiencing specific problems, circulating 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 % by weight.
|Statement: || |
The quantity of "solid contaminants" provides information on the overall pollution of the oil for investigation. The particles on the scaled 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 |
