Drop point
| OELCHECK test instrument: | Automatic drop point test device Mettler Toledo FP83HT, FP90 |
| Sample quantity: | approx. 5 g |
| Unit: | °C |
| Test result: | temperature at which the lubricating grease liquefies as a result of the disintegration of the soap structure (thickening agent) |
| Analysis for: | lubricating greases |
| Brief description: | The drop point is the temperature at which the lubricating grease liquefies as a result of the disintegration of the soap structure (thickening agent), i.e. when the liquefied grease drop falls through the opening in a nipple onto the bottom of the test tube. |
| Statement: | The drop point is mainly an indicator of quality control for manufacturers. Its significance as a measure of operating temperature limit is minimal, as there is no reliable formula based on which the upper temperature limit can be calculated. |
| Underlying test standard: | IP 396, ASTM D566, ASTM D2265 |
