ASTM F2582: Standard test method for impingement of acetabular prostheses

This test method describes a procedure to evaluate the acetabular component fatigue, deformation, and wear as well as femoral head assembly dislocation of a total hip replacement system under dynamic impingement conditions. The EndoLab® hip joint simulator is used for this type of testing. According to ASTM F2582 all UHMWPE acetabular components have to be artificially aged prior to testing (see ASTM F2003 ). All three in-vivo angular displacements (flexion/extension, abduction/adduction and internal/external rotation) are simulated and a constant joint reaction force is applied. The specimens are inspected every 200,000 cycles up to 1.0 million cycles are reached or failure of the system.
