Information on the most widely used ASTM standards within the materials testing industry
Model: UT1050, ASTM F543 torsion test
ASTM F543 standard specifies the torque required to measure the insertion and extraction of metal bone screws from standard materials, in order to confirm the consistency of the tested product. Load maintains 11.17N and rotates at a rate of 3r/min for 4 turns, followed by 4 turns.
UnitdTest UT1050 series Metal bone screw torsion testing equipment has a lightweight body, easy operation, and precise control, making it suitable for bone nail testing. We provide you with professional testing fixtures to meet standard requirements, as well as precise and effective test plans (SOP), and optional data post-processing software to reduce the difficulty of data processing and assist in the mechanical performance analysis of metal bone screws.
