ASTM F2068, ISO 7206 Cyclic Fatigue Testing of Artificial Hip Implant Prostheses, Hip Joint Prosthesis Testing

ISO 7206, ASTM F2068 is a testing standard designed to measure the durability of the metaphyseal bone components of hip implants. This testing procedure is applicable to implants with symmetrical planes, anterior or hyperbolic shapes of the epiphyseal bone, as well as prostheses used for restorative surgery. This test requires a dynamic testing machine and ISO 7206, ASTM F2068 fixtures. The lower part of the test sample is first embedded into a solid medium. Apply a cyclic load to the head of the sample, causing double-sided bending and twisting until the sample fractures or reaches the selected number of cycles.

The ISO 7206, ASTM F2068 standard specifies the test methods and performance requirements to determine the fatigue performance of the neck of the femoral components in partial and total hip arthroplasty under specific test conditions. The fatigue test is conducted with a frequency of 1 to 30 Hz, R=0.1, a maximum load of 5340N, for 10 million cycles or until sample failure occurs.

UnitedTest electromagnetic UTDS series fatigue testing devices provide precise sine wave load control with stable peaks, allowing you to obtain professional testing tools that meet the test condition requirements in the standard, as well as accurate and effective testing protocols (SOP), assisting in the mechanical performance analysis of femoral stems.
