BS 7251-8:1990

This standard BS 7251-8:1990 Orthopaedic joint prostheses is classified in these ICS categories:

• 11.040.40 Implants for surgery, prosthetics and orthotics

This Technical Report gives guidance on the methods available for the measurement of change of form (wear, creep, plastic deformation, etc.) of the bearing surfaces of hip joint prostheses when tested in hip joint simulators.

It highlights the strengths and weaknesses of the methods in an attempt to unify experimental technique and to increase the accuracy, precision and comparability of "wear test" data.

NOTE Attention is drawn to ISO/TR 9325 regarding hip joint simulators.

Methods available for measurement of wear, creep and plastic deformation of bearing surfaces of hip prostheses when tested in a hip joint simulator. Highlights strengths and weaknesses of methods.
