This part of ISO 7206 describes a method of deter-
mining 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 arm are secured together by a
locking conical taper or any other means and in which
the head and neck are separate components, and
which are made of metallic and non-metallic materials.
This part of ISO 7206 does not cover methods of ex-
amining the test specimens; these should be agreed
between the test laboratory and the party submitting
the specimen for test.
