ISO 14879-1, ASTM F1800 Knee Tibial tray Fatigue testing machine

ASTM F1800 Cyclic Fatigue Testing of Metal Tibial Tray Components of Total Knee Joint Replacements, covers a procedure for the fatigue testing of metallic tibial trays used in knee joint replacements using a cyclic, constant-amplitude force. It applies to tibial trays that cover both the medial and lateral plateaus of the tibia. This practice may require modifications to accommodate other tibial tray designs.

Applicable to tibial braces covering both the inner and outer sides of the tibia. 

Cantilever loading, 

with a frequency not exceeding 10Hz, 

R=0.1, 

for a period of 5 million cycles or until specimen failure in fatigue testing.

UnitedTest UTDS series electromagnetic equipment provides precise sine wave load control, offering comprehensive testing tooling to meet the experimental condition requirements in the standards, as well as accurate and effective experimental plans (SOP), helping in the mechanical performance analysis of tibial braces.
