Test Method for Measuring the Torsional Properties of Metallic Bone Screws (Withdrawn 2001)
1.1 This test method covers the testing of stainless steel, cobalt-based, and titanium-based bone screws for the determination of torsional yield strength, maximum torque, breaking angle, and torque versus angle of rotation.
The described test method is intended to be used as a means of evaluating the mechanical properties of bone screws.
