Disassembly tests - ASTM F1820

Standard test method for determining the forces for disassembly of modular acetabular devices


The ASTM F1820 test method describes the methodology used to measure the attachment strength between a modular acetabular shell and liner.

Disassembly tests are carried out in the following loading directions:

  • Axial disassembly
  • Offset pull-out or lever-out disassembly
  • Torque-out disassembly
