标准摘要
[中文适用范围]： 本部分描述了在实验室条件下确定髋关节假体头固定松开所需扭矩的方法。它适用于通过锁定锥形配合或其他方式固定的股骨部分，其中头和锥体是分开的组件，由金属或非金属材料制成。本部分不涉及试样检测方法；这些应由测试实验室与提交试样的方协商确定。 [外文原描述]： ISO 7206-13:2016 describes a method of determining the torque required, under specified laboratory conditions, to loosen the fixation of the head of hip joint prostheses in which the head is not intended to rotate relative to the neck. It applies to the femoral component of total or partial hip joint replacements in which the head and neck/stem (in the following referred to as cone) are secured together by a locking conical taper or any other means and in which the head and cone are separate components, and which are made of metallic or non-metallic materials. It does not cover methods of examining the test specimens; these should be agreed between the test laboratory and the party submitting the specimen for test.
