ISO 14243-2 - Implants for surgery — Wear of total knee-joint prostheses — Part 2: Methods of measurement
The ISO 14243-1 standard specifies the flexion/extension relative angular movement, the pattern of the applied force, the speed and duration of testing, the sample configuration and the test environment to be used for wear testing of total knee-joint prostheses in wear-testing machines under load control.
The ISO 14243-2 standard specifies a method of assessment of wear of the tibial component of total knee-joint prostheses using a gravimetric technique.
