Standard Practice for Cyclic Fatigue Testing of Metallic Stemmed Hip Arthroplasty Femoral Components Without Torsion (Withdrawn 2012)

ASTM F1440 – Standard Practice for Cyclic Fatigue Testing of Metallic Stemmed Hip Arthroplasty Femoral Components Without Torsion (Withdrawn 2012)

1.1 This practice describes a method for the fatigue testing of metallic stemmed femoral components used in hip arthroplasty. Thedescribed method is intended to be used to evaluate the comparison of variousdesigns and materials used for stemmed femoral components used in the arthroplasty.This practice covers procedures for the performance of fatigue tests using(as a forcing function) a periodic constant amplitude force.

1.2 This practice applies primarily to one-piece prostheses and modular components, with head in place such that prostheses should nothave an anterior/posterior bow, and should have a nearly straight sectionon the distal 50 mm of the stem. This practice may require modifications toaccommodate other femoral stem designs.

1.3 The values stated in SI units are to be regarded as the standard.
