In-page menu
Evaluation of endurance of metallic tibial trays used in artificial knee joint replacement.
Outline of Measurement Technology
Fatigue testing of the tibial tray is performed under laboratory conditions using an artificial knee joint in accordance with ISO 14879-1 or ASTM F1800.
Outline of Test
| Corresponding standards | ISO 14879-1, ASTM F1800 |
|---|---|
| Test environment | Constant temperature, constant humidity, in atmosphere |
| Test method | Compression bending fatigue test |
| Max. load | Dynamic test: 10 kN |
| Load ratio (min. load/max. load) | 10 |
| Loading frequency | ≤ 10Hz * |
| Max. number of cycles | 5 x 106 (ISO 14879-1) or 1 x 107 (ASTM F1800) |
* Please consult with JFE-TEC for loading frequencies exceeding 10 Hz.
