ASTM WK51649 Femoral knee component fatigue testing system - Fatigue Testing of Total Knee Femoral Components Under Closing Conditions
ASTM WK51649 is a draft standard (work item) under development by ASTM Committee F04.22 on Arthroplasty . It proposes a test method for evaluating the fatigue resistance of total knee femoral components under closing conditions, similar in scope to ASTM F3210. (ASTM F3210-22e1 Standard Test Method for Fatigue Testing of Total Knee Femoral Components Under Closing Conditions)
ASTM WK51649 Fatigue testing of the metal femoral component of a total knee joint prosthesis is conducted to establish the F-N curve at different load levels and to determine the fatigue limit of the sample under 10 million cycles.
Test Methodology:
![]() | ![]() |
| Aspect | ASTM F3210 | ASTM WK51649 |
|---|---|---|
| Status | Approved standard (F3210-22e1). | Draft work item. |
| Cycle Count | 5 million cycles. | Proposed 10 million cycles. |
| Scope | Fatigue testing under closing conditions. | Similar scope, potential additional features. |
| Recognition | FDA/CE recognized. | Not yet recognized. |
| Documentation. | Complete standard with detailed procedures. | Limited public documentation available. |
At this time, ASTM F3210 remains the only recognized standard for this testing purpose. ASTM WK51649 should be considered a work in progress that may eventually lead to an updated or alternative standard once fully developed and approved through ASTM's consensus process.
