| OELCHECK test instrument: | Anton Paar rheometer Physica MCR 301 cone/plate measuring system |
| Sample quantity: | Approx. 1 - 5 grams |
| Unit: | Pa·s |
| Test result: | Shear viscosity |
| Analysis for: | Lubricating greases |
| Brief description: | The measuring system is filled with approximately 2 g of the homogenised and deaerated grease, adjusted and tempered. In a standardised testing procedure, the (apparent) dynamic viscosity at a set shear rate is determined and the shear viscosity at the beginning and the end of the testing procedure and the shear viscosity decrease in percentage terms are displayed. |
| Statement: | Based on the shear viscosity and its stability following shear stress, the rheological properties of a lubricating grease and its changes under shear load are diagnosed. This figure allows conclusions to be drawn on the grease's suitability for speeds. |
| Underlying test standard: | DIN 51810-1 |
