1 Scope
This document specifies methods of determining the compressive (fracture) or the tension (disassembly) loads required, under specific laboratory conditions, to cause failure of a modular head system.
This document applies to components made of metallic and non-metallic materials, such as femoral heads of partial or total hip-joint replacements of modular construction (i.e. a head/neck conical taper connection).
This document excludes methods of examining and reporting the test specimens.
NOTE The method for determining the compressive (fracture) load to failure utilizes quasi-static loading of the modular femoral heads. ASTM F2345 can be used for dynamic compressive loading of ceramic modular femoral heads and utilizes the same test set-up, assembly and loading procedure described in this method.
