1 Scope
This part of ISO 7206 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.
This part of ISO 7206 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.
