本文件规定了在特定实验室条件下确定导致模块化头部系统故障所需的压缩（断裂）或拉伸（拆卸）载荷的方法。 本文件适用于由金属和非金属材料制成的部件，例如模块化结构的部分或全部髋关节置换术的股骨头（即头部/颈部锥形连接）。 本文件不包括检验和报告试样的方法。

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.
