This part of ISO 7206 specifies requirements for the articulating surfaces of those types of total and partial hip
joint prostheses that provide a joint replacement of ball and socket configuration, as follows:
a) sphericity and surface finish requirements for metallic and ceramic femoral prostheses for partial hip joint
replacement that are in accordance with classification a) of ISO 7206-1;
b) sphericity and surface finish requirements for bipolar heads with plastics inner surfaces which articulate
on femoral components that are in accordance with classification a) of ISO 7206-1 and with metallic or
ceramic outer surfaces which articulate on the biological acetabulum;
c) sphericity and surface finish requirements and dimensional tolerances for plastics acetabular components
that are in accordance with classification b) of ISO 7206-1;
d) sphericity and surface finish requirements and dimensional tolerances for metallic or ceramic femoral
components of total hip joint prostheses that are in accordance with classification c) of ISO 7206-1, designed
to articulate on plastics acetabular components.
