The tests according to ISO 7206-4 and ISO 7206-6 focus on the stem and neck regions of the femoral component of hip replacements. Under specified cyclic loads and numbers of cycles, the fatigue strength of the hip stem is evaluated. The fixation method and applied loads vary depending on the design and length of the stem, which is classified as short stem, standard stem, or revision stem.

Additional requirements arise depending on whether the design is anatomical or straight. If the product features taper connections in the stem or neck area, the tests are performed in a saline bath at 37°C.

Beyond the prescribed standard conditions, we offer, in consultation with our customers, testing with higher loads, increased cycle numbers, and load increments.
