ISO 12108 Fatigue Testing of Metallic Implants involves a series of tests that evaluate the durability and reliability of metallic implants under cyclic loading conditions. The test procedure includes:
1. Specimen Preparation: Prepare specimens according to ISO 6892-1:2018 (Metallic materials -- Tensile testing -- Part 1: Method of test at room temperature).
2. Loading Conditions: Apply a cyclic load to the specimen, as specified in ISO 12108:2015.
3. Fatigue Testing: Conduct fatigue testing using an axial force-controlled method, with a loading frequency and amplitude as specified in ISO 12108:2015.
4. Test Duration: Test for a duration of at least 100,000 cycles or until failure occurs.
5. Data Analysis: Analyze test data to determine the number of cycles to failure (Nf) and calculate the fatigue strength (σf).
